Background and Purpose
The Pinellas Bayway Structure ‘‘C’’
bridge has a vertical clearance of 25 feet
in the closed position and the Corey
Causeway bridge has a vertical
clearance of 23 feet in the closed
position.
The current operating regulations per
33 CFR 117.287(e), the draw of the
Pinellas Bayway Structure ‘‘C’’ bridge,
mile 114, at St. Petersburg Beach shall
open on signal; except that from 7 a.m.
to 7 p.m., the draw need open only on
the hour, twenty minutes past the hour,
and forty minutes past the hour. Per 33
CFR 117.287(f), the draw of the Corey
Causeway (SR 693) bridge, mile 117.7 at
South Pasadena, shall open on signal;
except that, from 8 a.m. to 7 p.m.
Monday through Friday, and 10 a.m. to
7 p.m. Saturdays and Sundays and
Federal holidays, the draw need to open
only on the hour, twenty minutes after
the hour, and forty minutes after the
hour.
The local mayor has requested that
the Coast Guard evaluate a twice an
hour schedule. The Florida Department
of Transportation, the bridge owner, has
a concern related to the length of time
during bridge openings on the weekends
due to the accumulation of vessels
between openings which may directly
PO 00000
Frm 00030
Fmt 4700
Sfmt 4700
impact vehicle traffic. For this reason,
FDOT will be monitoring the traffic flow
through the area during this test and
may recommend that the test be
terminated at any point that vehicle
traffic patterns show a detriment rather
than an improvement in traffic flow.
This test may have a minor impact on
vessel traffic as there will be two
openings an hour rather than three
during these same time periods.
This deviation will start on 7 a.m. on
January 26 and will continue until 7
p.m. on April 25, 2009, unless otherwise
terminated/cancelled due to heavier
than normal traffic patterns. The
Pinellas Bayway Structure ‘‘C’’ and
Corey Causeway bridges will open on
demand except that from 7 a.m. to 7
p.m. daily both bridges will open on the
hour and half-hour, seven days a week.
Vessels able to pass under the bridges
without an opening may do so at any
time. Public vessels of the United States
and tugs with tows must be passed at
any time.
In accordance with 33 CFR 117.35(e),
the drawbridge must return to its regular
operating schedule immediately at the
end of the designated time period. This
deviation from the operating regulations
is authorized under 33 CFR 117.35.
Dated: January 15, 2009.

Summary of the Report and Order and
Memorandum Opinion and Order
1. On May 13, 2004, the Commission
adopted a Notice of Proposed Rule
Making (NPRM), 71 FR 66897,
November 17, 2006, in this proceeding
in which it proposed to allow
unlicensed operation in the TV bands at
locations where frequencies are not in
use by licensed services. To ensure that
no harmful interference will occur to TV
stations and other authorized users of
the spectrum, the Commission proposed
to define the conditions under which a
TV channel is unused and to require
unlicensed devices to incorporate
‘‘smart radio’’ features to identify the
unused TV channels in the area where
they are located. For the purpose of
minimizing interference, the
Commission proposed to classify
unlicensed TVBDs in two general
functional categories. The first category
would consist of lower power
‘‘personal/portable’’ unlicensed devices,
such as Wi-Fi-like cards in laptop
computers or wireless in-home local
area networks (LANs). The second
category would consist of higher power
‘‘fixed’’ unlicensed devices that would
operate from a fixed location and could
be used to provide commercial services
such as wireless broadband Internet
access. It proposed to require that
personal/portable devices operate only
when they receive a control signal from
a source such as a TV station or FM
radio station that identifies the vacant
TV channels in that particular area. The
Commission also requested comments
on an approach that would require that
fixed devices incorporate a geo-location
method such as a Global Positioning
System (GPS) receiver or be
professionally installed, and that they
access a database system to identify
vacant channels at their location. The
Commission further sought comment on
the use of spectrum sensing to identify
vacant TV channels, but did not propose
any specific technical criteria for
spectrum sensing.
2. The comments received in response
to the NPRM were divided between the
prospective manufacturers and users of
unlicensed devices who believe
adequate safeguards can be put in place
to prevent harmful interference to
authorized services, and the existing
users of the TV bands who are
concerned about potential interference.
A number of broadband equipment
manufacturers, trade associations and
PO 00000
Frm 00031
Fmt 4700
Sfmt 4700
7315
other parties supported allowing
unlicensed operation in the TV bands.
These parties generally stated that
unlicensed devices could operate in the
TV bands without causing interference
to authorized services. They further
stated that allowing such operation in
the TV bands could improve access to
broadband communications by taking
advantage of the favorable propagation
characteristics of the TV spectrum and
that this would result in more efficient
use of this spectrum.
3. Full service and low power TV
broadcasters generally opposed allowing
unlicensed operation in the TV bands,
expressing concern that unlicensed
devices operating under the proposed
rules would cause interference to TV
reception, particularly in weak signal
areas. Several parties also expressed
concern that unlicensed devices
operating in close proximity to TV
receivers would cause direct pick-up
interference potentially affecting all
channels. Manufacturers and users of
wireless microphones and other
broadcast auxiliary services submitted
that unlicensed devices would cause
harmful interference to those services.
Those parties recommended that the
Commission take a number of steps to
protect auxiliary services. Land mobile
interests expressed concern about
allowing unlicensed operation on
channels 14–20 in any part of the
country because devices could be
transported into areas where those
channels are used for PLMRS/CMRS
operations.
4. On October 12, 2006, the
Commission adopted the First R&O/
Further NPRM, 71 FR 66897, November
17, 2006, in this proceeding. In that
action, the Commission determined that
the record received in response to the
NPRM did not contain sufficient
information for it to adopt final rules for
unlicensed TVBDs. The Commission
did, however, make a number of initial
decisions regarding TVBDs. It decided
to permit fixed unlicensed power
devices to operate in the TV bands at
times and locations where the spectrum
is not already being used by other
authorized services. It also decided not
to permit operation of unlicensed
TVBDs on channel 37, which is used by
radio astronomy and wireless medical
telemetry services, and on TV channels
52–69, as that spectrum has been
reallocated for other services and will
no longer be part of the TV bands after
the DTV transition. The Commission
further decided to prohibit operation of
personal/portable TV band devices on
TV channels 14–20 to avoid potential
conflicts with public safety services on
those channels. In addition, the
E:\FR\FM\17FER1.SGM
17FER1
jlentini on PROD1PC65 with RULES
7316
Federal Register / Vol. 74, No. 30 / Tuesday, February 17, 2009 / Rules and Regulations
Commission stated that it will not
permit marketing of TV band devices to
commence until February 18, 2009, the
date on which all primary, full service
TV stations will be in operation on their
permanent DTV channels.
5. In the First R&O/Further NPRM, the
Commission also asked questions and
set forth additional proposals with
regard to the provisions necessary to
implement complete and final rules for
unlicensed TV band devices. While the
Commission continued to focus on
devices operating on an unlicensed
basis, it also sought comment on
whether such devices should instead
operate on a licensed or hybrid basis.
The Commission recognized the
importance of conducting testing to
ensure that whatever standards are
ultimately adopted will protect
incumbent radio services from
interference and indicated that it
intended to conduct extensive testing to
assess the potential interference from
low power devices operating in the TV
bands. It also requested further
comment and information on the means
that TVBDs, both fixed and personal/
portable, should be required to use to
determine the availability of unused
spectrum. It specifically requested
comment on whether it should allow
personal/portable devices to rely on
spectrum sensing and, if so, the
technical features and parameters of the
sensing capability to be required. The
Commission observed that IEEE 802.22
is considering different sensing
threshold detection levels depending on
the nature of the source signal, with
levels as low as ¥116 dBm, and invited
comment on this value or alternative
values for the detection threshold. It
also made specific proposals for
additional parameters of spectrum
sensing capabilities and other technical
requirements. The Commission sought
comment on whether TV band devices
should be permitted to operate on TV
channels 2–4, and whether fixed TV
band devices should be permitted to
operate on TV channels 14–20. The
Commission also sought additional
comments on several issues relating to
the geo-location/database access and
control signal approaches discussed in
the NPRM.
6. The comments responding to the
First R&O/Further NPRM are again
divided on certain of the major issues in
this proceeding. Two groups, one a
coalition of hardware and software
companies consisting of Dell, Google,
HP, Intel, Microsoft and Phillips (the
White Space Coalition) and the other a
group of public interest/consumer
organizations and wireless internet
service providers (WISPs), led by the
VerDate Nov<24>2008
16:58 Feb 13, 2009
Jkt 217001
NAF, strongly support low power,
unlicensed use of the TV bands. In
addition, some other manufacturers and
a number of WISPs express support for
that approach separately from these
groups. Proponents of unlicensed
devices believe that the Commission
should allow both fixed and personal/
portable devices. They also support
allowing personal/portable devices to
rely solely on spectrum sensing to
determine the available channels at
their location. The White Space
Coalition supports limiting unlicensed
operation to channels 21–51 (excluding
37), while the group led by the NAF
believes that operation should be
permitted on as many channels as
possible, including channels 2–4 and
channels 14–20 in locations where
public safety and land mobile services
are not using them.
7. Full service and low power TV
broadcasters and cable TV interests
generally state that any new services in
the TV bands should be licensed to
reduce the likelihood of interference to
incumbent services. They oppose the
introduction of personal/portable
devices at this time and believe that any
new services should be limited to fixed
operation. Broadcasters contend that
spectrum sensing alone is inadequate to
protect against interference to broadcast
operations and that sensing must be
combined with geo-location/database
access to ensure that low power devices
do not operate inside the protected
service contours of co-channel or
adjacent-channel TV stations. Low
power TV and translator operators
express concern that low power
unlicensed devices would cause
interference to viewers who rely on
reception outside their stations’
protected service contours, while cable
interests express concern about possible
interference to reception of TV signals
by cable headends that are located
outside TV stations’ protected contours.
Both broadcast and cable interests
express concern about direct pick-up
interference to TV receivers, particularly
from personal/portable devices.
8. Wireless microphone
manufacturers and users again
recommend that the Commission adopt
a number of requirements to prevent
interference to wireless microphones,
including: (1) Limiting new low power
devices to fixed operation, (2)
prohibiting new low power devices
from operating on channels adjacent to
occupied TV channels and/or reserving
six vacant TV channels in each market
for wireless microphones to ensure that
spectrum is available for their use, (3)
requiring new low power devices to
incorporate spectrum sensing to detect
PO 00000
Frm 00032
Fmt 4700
Sfmt 4700
wireless microphones, and (4) requiring
new low power devices to sense for the
presence of a ‘‘smart beacon’’ that
would be operated when wireless
microphones are in use in an area
(Shure has since repudiated its support
for a beacon requirement). Public safety/
land mobile interests believe that new
low power devices should not be
allowed to operate on channels 14–20
anywhere in the country because of the
difficulties in enforcing geographic
restrictions on operation.
9. On March 30, 2007, the
Commission’s Office of Engineering and
Technology released a report on the
results of its DTV receiver testing
program, see DA 07–3457, 22 FCC Rcd
13846 (2007). This testing program
examined the out-of-channel
interference rejection performance of a
representative sample of eight DTV
receivers with fifth generation tuners
that were available in 2005 and 2006. A
total of 2055 individual measurements
were performed on these receivers. Each
test involved feeding a desired signal to
the television under test and injecting
an interfering signal on a different
channel or combination of channels.
The different tests varied the level of the
desired signal and interfering signal(s).
In these tests, no receiver appeared to
fully achieve the Advanced Television
Systems Committee’s (ATSC)
recommended guidelines for
interference rejection performance—
guidelines that are generally more
stringent than the receiver performance
assumptions on which current DTV
interference protection criteria are
based. However, the tests did show that
the performance of digital television
receivers exceeds the performance
levels on which the Commission’s
digital television service and
interference rules are based.
10. On July 31, 2007, the Office of
Engineering and Technology released a
technical report on an initial study of
prototype TV band devices that were
submitted to the Commission’s
Laboratory for testing. This report
evaluated the performance of two
samples of prototype devices; one
device had both sensing and
transmitting capabilities (although the
two functions were not linked) and the
other had only sensing capability. This
testing found that one of the two devices
was generally able to reliably detect TV
signals in the laboratory bench tests at
the claimed ¥114 dBm sensing level,
but did not perform well sensing
wireless microphones. This device was
not tested in the field at the
manufacturer’s request. The other
device was not able to reliably sense
either TV or wireless microphone
E:\FR\FM\17FER1.SGM
17FER1
jlentini on PROD1PC65 with RULES
Federal Register / Vol. 74, No. 30 / Tuesday, February 17, 2009 / Rules and Regulations
signals at the ¥114 dBm level in either
the Laboratory bench tests or in field
tests. The builder of this device
subsequently determined that the
device’s sensing function was not
operating properly. In an anecdotal
observation, the transmitter of the
second device was found to cause cochannel and adjacent channel
interference to TV service at distances of
87 meters and 47–50 meters,
respectively.
11. Also on July 31, 2007, the Office
of Engineering and Technology released
a second technical report describing
direct pick-up interference tests of three
digital cable ready television receivers.
In these tests, three digital cable ready
(DCR) receivers connected directly to
cable service were examined for their
susceptibility to interference from
devices such as might operate within
the TV white spaces. Tests were
performed with the interfering signal
source separated from the DCR receiver
by distances of 2 meters or ten meters
and, in most observations, by a
residential wall. These tests showed that
a signal as low as 6.3 dBm EIRP could
cause interference at a distance of two
meters and that a signal as low as 15.3
dBm could cause interference at a
distance of 10 meters. While these tests
were limited in scope (only three
receivers were tested), they nonetheless
provide an empirical demonstration of
the potential for such interference at
relatively low power levels.
12. On October 15, 2008, the Office of
Engineering and Technology issued a
technical report on a second phase of its
study of sample prototype TV band
devices. This second phase study
examined the performance of prototype
devices from five parties. All of these
devices had capabilities for sensing TV
signals, three had capabilities for
sensing wireless microphones and one
(that of Adaptrum) had a transmit
capability (this transmit capability was
not linked to the device’s sensing
capabilities). One of the devices (that of
Motorola) also had a geolocation/
database access capability.
13. In the laboratory tests of TV
signals, the Phase II prototype devices
were able to detect a ‘‘clean,’’ i.e.,
unfaded, DTV signal on a single channel
at levels in the range of ¥116 dBm to
¥126 dBm. The detection threshold
sensitivity of the devices varied from
¥106 dBm to ¥128 dBm when
recorded off-air DTV signals, which
included multi-path fading and other
‘‘real-world’’ distortion, were used.
When the devices were tested with DTV
signals present in adjacent channels, the
staff found that in the presence of
moderate-to-strong signals in a first
VerDate Nov<24>2008
16:58 Feb 13, 2009
Jkt 217001
adjacent channel, the detection
threshold sensitivity of all of the devices
was severely impacted. For some of the
devices, the degradation in the detection
sensitivity was as much as 60–70 dB. In
some cases, the degradation was such
that the detection threshold could not
be measured. The Phase II Measurement
Report indicates that this could impact
significantly the ability of the devices to
reliably detect TV signals within
stations’ service areas.
14. TV sensing field tests were
performed at nine locations with four of
the prototype devices. In most cases, the
devices correctly reported channels as
occupied when the device was operated
within the service contour of the
stations broadcasting on those channels
and viewable signals were observed on
the channels. In some instances,
however, three of the devices
incorrectly reported channels as
unoccupied (available) when the device
was operated within a station’s service
contour and the signal was viewable.
All of the devices reported some
channels as occupied when the WSD
was operated outside of the service
contours of stations broadcasting on
those channels whether the signal was
viewable or not. In addition, one device
generally reported most channels
occupied, whether the device was
operating inside or outside any service
contours and whether the signal was
viewable or not. During the field tests,
the Motorola device’s geolocation/
database access feature was used in
combination with its sensing
capabilities. In those tests, the Motorola
device correctly reported all occupied
channels used by stations within whose
contours the WSD was operated.
15. The second phase study also
examined the ability of devices to sense
wireless microphones designed to
operate under part 74 of our rules. The
two operating devices with wireless
microphone sensing capability, those of
Philips and I2R, were tested in the
laboratory for their ability to detect
wireless microphones (models using
both FM/analog and digital) operating
within UHF TV channels. With no other
signals present, the devices were able to
detect wireless microphones at levels
ranging from ¥103 dBm to ¥129 dBm
depending on the type of microphone,
and the device. However, in the
presence of DTV signals in adjacent
channels, the detection threshold of
both devices was degraded such that it
affected the ability of the devices to
reliably detect the microphone signals.
16. Finally, the second phase study
conducted tests with the Adaptrum
device’s transmitter. The device’s
transmitter was characterized in the
PO 00000
Frm 00033
Fmt 4700
Sfmt 4700
7317
laboratory and then used to investigate
interference potential to DTV signal
reception. Anecdotal tests demonstrated
that co-channel interference would
occur at line-of-sight distances of up to
360 meters at an EIRP level of
approximately +7 dBm when the DTV
set was receiving a weak signal off-theair using a receive antenna at a height
of 9.3 meters. No interference was
observed when the device transmitted
on an immediate adjacent channel even
with the transmitter in close proximity
to the receiver with a roof-top antenna.
No other configurations were tested for
interference. Anecdotal tests with the
Adaptrum transmitter were performed
at two field sites to assess the
interference potential from a TVBD
transmitter to cable television reception
via direct pick-up of signals by cable
system components. These tests showed
that under certain circumstances, when
the transmit antenna was placed in
close proximity to a cable connected
TV, direct pick-up interference
occurred. The report indicated that the
direct pick-up interference potential
appears to be highly dependent on the
interconnection among the various
receive system components (e.g., cable
amplifiers, splitters and set-top boxes)
being used.
17. In the Second Report and Order,
the Commission adopted rules to allow
unlicensed radio transmitters to operate
in the broadcast television spectrum at
locations where that spectrum is not
being used by licensed services (this
unused TV spectrum is often termed
‘‘white spaces’’). This action will open
for use a significant amount of spectrum
with very desirable propagation
characteristics that has heretofore lain
fallow. These new rules will allow the
development of new and innovative
types of unlicensed devices that provide
broadband data and other services for
businesses and consumers without
disrupting the incumbent television and
other authorized services that operate in
the TV bands. In addition, because
transmissions on frequencies in the TV
bands are less subject to propagation
losses than transmissions in the
spectrum bands where existing low
power broadband unlicensed operations
are permitted, i.e., the 2.4 GHz and 5
GHz bands, the Commission anticipates
that allowing unlicensed operation in
the TV bands will benefit wireless
Internet service providers (WISPs) by
extending the service range of their
operations. This will allow wireless
broadband providers that use
unlicensed devices to reach new
customers and to extend and improve
their services in rural areas. We

jlentini on PROD1PC65 with RULES
7318
Federal Register / Vol. 74, No. 30 / Tuesday, February 17, 2009 / Rules and Regulations
anticipate that allowing use of the TV
white spaces by unlicensed devices will
have significant benefits for both
businesses and consumers and thereby
promote more efficient and effective use
of the TV spectrum.
18. The Commission adopted a plan
that will allow both fixed and personal/
portable unlicensed devices to operate
on unused television channels in
locations where such operations will
not result in harmful interference to TV
services (including reception by cable
headends and low power TV stations,
i.e., TV translator, low power TV, TV
booster, and Class A TV stations) and
other services that use the TV bands.
The Commission recognizes the
importance of protecting licensed
services from harmful interference and
the novel challenges involved in
reliably identifying unused TV
channels. Therefore, it is taking a
cautious and conservative approach in
this plan, balancing the need to provide
sufficient opportunities for proponents
to develop viable unlicensed TV band
devices (TVBDs) with measures to
ensure that such devices fully protect
the important licensed services that
operate in the TV bands. In allowing the
introduction of unlicensed TVBDs, the
Commission also believes it is important
to avoid the possibility of disrupting or
causing uncertainty in the DTV
transition, the current ongoing process
whereby TV stations are changing from
analog to digital (DTV) operation. As set
forth in the First Report and Order and
Further NPRM of Proposed Rulemaking
(First R&O/Further NPRM) in this
proceeding, the Commission addressed
this concern with regard to the DTV
transition by restricting the marketing of
unlicensed TVBDs until February 18,
2009, the date when the DTV transition
will end and all full-power TV stations
will be operating on a single channel,
and only with digital signals.
19. The Commission anticipates that
the capabilities of products for operating
in this spectrum will develop and
evolve over time and that much will be
learned about the potential for
unlicensed TVBDs to cause interference
to licensed services and how to avoid
that interference. Therefore, the
Commission may need to revisit these
rules to make adjustments both to
provide more flexibility for unlicensed
devices and to refine the protections for
licensed services. Consistent with our
objective to allow unlicensed TVBDs to
operate with the most flexibility and
capabilities possible consistent with
protection of licensed services, the
Commission has directed its staff to
conduct a review and report to the
Commission in two years from the date
VerDate Nov<24>2008
16:58 Feb 13, 2009
Jkt 217001
of this Second Report and Order on the
state of these devices, including the
types of devices on the market, the
extent of their implementation,
technical developments, any
interference problems that may have
arisen, and aspects of the rules that
should be altered to increase features
and opportunities for use or to address
conflicts.
20. The Commission also denied all
aspects of a petition for reconsideration
submitted by the New America
Foundation and the Champaign Urbana
Wireless Network (NAF/CUWN). In
particular, the Commission denied their
request that it (1) Not re-open the issue
of whether to permit new uses of the TV
bands on a licensed or unlicensed basis;
(2) allow personal/portable devices on
channels 14–20; and (3) allow marketing
of new unlicensed TV band devices
prior to the end of the DTV transition.
21. Overview of Rules for Unlicensed
TV Band Devices. The new rules
provide for operation of two types of
unlicensed TVBDs that may provide
broadband data and other types of
communications services: (1) Fixed
devices, which will operate from a fixed
location with relatively higher power
and could be used to provide a variety
of services including wireless
broadband access in urban and rural
areas, and (2) personal/portable devices,
which will use lower power and could,
for example, take the form of devices
such as Wi-Fi-like cards in laptop
computers or wireless in-home local
area networks (LANs). In order to
operate without causing interference to
licensed services, both types of devices
will be required to be able to reliably
determine which channels are occupied
by licensed operations at their location
at any given time and to avoid
interfering with services on those
channels using the following methods.
Devices will be required to identify
unused channels as follows:
(a) A fixed device must employ both
geo-location/database access and
spectrum sensing capabilities that
enable the device to listen for and
identify the presence of signals from
other transmitters; the geo-location
function for a fixed device may also be
performed by a professional installer;
(b) A personal/portable device must
either (1) be under the control of a fixed
device or a personal/portable device
that employs geo-location/database
access and spectrum sensing or (2)
employ geo-location/database access
and spectrum sensing itself.
22. In addition, the Commission
adopted rules that will allow for
certification of personal/portable
devices that do not include geo-location
PO 00000
Frm 00034
Fmt 4700
Sfmt 4700
and database access capabilities and are
not controlled by another device but
rather determine available channels
using spectrum sensing, perhaps in
combination with some other
techniques. These devices will be
required to meet a ‘‘proof of
performance’’ standard that they will
not cause harmful interference to
incumbent radio services. Such devices
will be subject to all of the other
requirements for personal/portable
devices but would be limited to 50
milliwatts (mW) EIRP rather than the
100 mW authorized for personal/
portable devices for which available
channels are determined based on the
geo-location and database method. The
certification process will require
submittal of a sample for testing in our
laboratory and in the field similar to the
process that the FCC Laboratory
followed for testing of TV band devices.
The sample device must be a fully
functioning pre-production prototype,
identical to the device that will be
marketed except for cosmetics. The
testing will be open to the public. The
application must also show how the
device will protect the various
incumbent radio services discussed. The
determination of whether to certify the
device will be based on a demonstrated
ability to avoid causing harmful
interference with an extremely high
degree of reliability. If the device is
certificated, the Commission will permit
routine certification of other devices
that have identical characteristics (i.e.,
have the identical electrical
characteristics and antenna system). It
will endeavor to complete the
certification process within 180 days of
submittal of the device for testing,
barring any unforeseen circumstances.
23. Fixed Devices. Fixed devices will
be allowed to communicate with other
fixed devices and with personal
portable devices. These devices will be
required to determine their geographic
location through an incorporated geolocation capability or from a
professional installer and to access and
register with a database system that
contains records of protected services
and receive back a list of the available
channels at their location. In addition,
fixed devices will be required to operate
with antennas mounted outdoors and to
use spectrum sensing to identify any
wireless microphone operations and any
other protected signals that might be
present at their location but do not
appear in the database. These devices
will be required to sense, at levels as
low as ¥114 dBm, TV signals (digital
and analog), wireless microphone
signals, and signals of other services
E:\FR\FM\17FER1.SGM
17FER1
jlentini on PROD1PC65 with RULES
Federal Register / Vol. 74, No. 30 / Tuesday, February 17, 2009 / Rules and Regulations
that operate in the TV bands on
intermittent basis. Fixed devices will be
allowed to operate at up to 1 watt (W)
transmitter output power and with a
gain antenna to achieve 4 W equivalent
isotropically radiated power (EIRP), and
to communicate with other fixed
devices and personal/portable devices,
except that they may not communicate
with personal/portable devices when
operating on channels in the range 2–20.
The plan for fixed devices is similar to
the provisions of the draft standard for
TVBDs under consideration by IEEE
802.22.
24. Personal/portable Devices.
Personal/portable devices will be
allowed to communicate with fixed
devices and with other personal/
portable devices. These devices will be
allowed to operate in two different
modes: (1) Mode I—client, whereby a
personal/portable device is controlled
by a fixed or a personal/portable device
operating in Mode II that has
determined the available channels in
the area and/or (2) Mode II—
independent, whereby a personal/
portable device determines the available
channels using its own internal geolocation/database access capabilities.
Personal/portable operations will be
permitted at up to 100 mW EIRP, with
no antenna gain, except that when
operating on a channel adjacent to a TV
station or other licensed station/service
and within the protected coverage area
of that service, operations will be
limited to 40 milliwatts. A device
operating in Mode II using its own
internal geo-location and database
access capabilities will be allowed to
communicate with other personal/
portable devices and function as the
master device in a master/client link
with another personal/portable device.
Devices operating in either mode will be
required to sense TV signals, wireless
microphone signals, and signals of other
services that operate in the TV bands,
including those that operate on an
intermittent basis, at levels as low as
¥114 dBm. Personal portable devices
will not be required to register with the
database system.
25. All Devices. All unlicensed TV
band fixed and personal/portable TV
band devices will be permitted to
operate on TV channels 21–51,
excluding channel 37. In addition, fixed
TVBDs that only communicate with
other fixed TVBDs will be permitted to
operate on channels 2 and 5–20, except
that they must avoid operation on
channels used by private land mobile
radio service (PLMRS), i.e., public
safety, and commercial mobile radio
service operations on channels in
certain markets and areas adjacent to
VerDate Nov<24>2008
16:58 Feb 13, 2009
Jkt 217001
them. Also, in individual markets where
there are Private Land Mobile Radio
Service or Commercial Mobile Radio
Service (PLMRS/CMRS) operations on
channels 14–20, two channels in the
range 21–51 will be reserved for
operation by wireless microphones such
that TVBDs will not be permitted on
those channels. This plan for channel
use is consistent with the requests of the
various white space proponents and
would reserve channels for a ‘‘safe
harbor’’ for operation of wireless
microphones and ensure protection of
the public safety and other land mobile
services that use channels 14–20. At this
time, we are only permitting fixed
TVBDs to operate on channels that are
not immediately next to (first adjacent
on either side of) the channel of a TV
station; personal portable devices will
be allowed to operate on first adjacent
channels to a TV station subject to the
power limitation indicated. All
unlicensed TV band devices will be
required to limit their out-of-band
emissions in the first adjacent channel
to a level 55 dB below the power level
in the channel they occupy, as
measured in a 100 kHz bandwidth. In
addition, all TVBDs will be required to
comply with a more stringent out-ofband emissions band at the edges of
channels 36 and 38 that are adjacent to
channel 37 in order to protect medical
telemetry devices on that channel 37.
Fixed devices will also be required to
periodically transmit a signal with their
identification when they are operating.
This will facilitate identification of
sources of interference. The database
system for fixed stations and personal/
portable devices with geo-location and
database access capability will be
managed by a database manager or
managers selected by our Office of
Engineering and Technology. The
specific provisions of this plan are
presented below.
TV Bands Database System
Requirements
26. All unlicensed fixed TV band
devices and all personal/portable
devices, except for those that operate in
Mode I under control of a fixed or Mode
II personal/portable device, will be
required to access a TV bands database
to obtain information on the available
channels at their location and all
unlicensed fixed TVBDs will be
required to register their operations. In
the NPRM and the First R&O/Further
NPRM, the Commission made proposals
and asked for comment on a number of
specific provisions relating to this
database system. In particular, the
Commission requested comment on the
information about authorized stations
PO 00000
Frm 00035
Fmt 4700
Sfmt 4700
7319
that should be in a database, such as
geographic coordinates, type and class
of station, transmit power level, antenna
height and other antenna characteristics,
the means by which an unlicensed
device would access the database, and
how often the database would need to
be updated. The Commission addresses
the specific plan for operation of the
database system, including the
information to be stored in the database,
the requirements that apply to
unlicensed TVBDs for accessing the
database system, the responsibilities of
a database administrator, and database
administrator selection.
27. Database system plan and
operation: The Commission has adopted
a database plan that will provide for
efficient and effective management of
licensee and TVBD records and the
identification of available channels for
TVBDs. As an initial matter, it will
consider authorizing more than one
entity to operate a TV bands database.
Thus, depending on expressed interest
to a solicitation for database managers,
the Commission could select multiple
database administrators that could offer
services on a competitive basis. In this
regard, the Commission is mindful that
sufficient safeguards must be put in
place to ensure that a TVBD would
receive the same set of available
channels regardless of which database it
queries such that entities compete solely
on the basis of cost and speed and
efficiency of service. The database(s)
will be a privately owned and operated
service that unlicensed TV band devices
must contact to obtain information on
channel availability at the locations
where they are operated and, in the case
of fixed devices, to register their
operation at those locations. The
Commission will permit database
administrators to charge fees for
registration of fixed devices and the
provision of lists of available channels
to fixed devices and personal/portable
devices. It believes that third parties
will be in the best position to develop
and manage a database in a fair and
equitable manner and to address the
day-to-day operational demands. Any
TV bands database will be required to
contain information on: (1) All of the
authorized services that operate in the
TV bands using fixed transmitters with
designated service areas, including full
service and low power TV stations, (2)
the service paths of broadcast auxiliary
point-to-point facilities, (3) the
geographic regions served by PLMRS/
CMRS operations on channels 14–20, (4)
regions served by the Offshore
Radiotelephone Service, and (5) the
locations of cable headends and low
E:\FR\FM\17FER1.SGM
17FER1
jlentini on PROD1PC65 with RULES
7320
Federal Register / Vol. 74, No. 30 / Tuesday, February 17, 2009 / Rules and Regulations
power TV receive sites that are outside
the protected contours of the TV
stations whose signals they receive. In
addition, a TV bands database will be
required to contain the locations of
registered sites where wireless
microphones and other low power
auxiliary devices are used on a regular
or scheduled basis. A TV bands
database will be required to register
unlicensed TV band devices in
accordance with the rules and to
provide such devices with a list of the
available channels at the specific
locations where they are operating.
28. Unlicensed TV band devices,
except for those operating as a client to
a either a fixed device or a personal/
portable device operating in Mode II,
will be required to contact a TV bands
database through the Internet to obtain
a list of available channels at their
location in accordance with the rules set
forth herein. Database administrator(s)
will define protocols so that TV band
devices can access a database
automatically without human
intervention. A TV bands database will
calculate the television channels that
are available for use by unlicensed TV
band devices at their individual
locations based on the information in
the database and consistent with the
separation distances set forth in the
rules and then return a list of those
channels to the TV band device on an
approximately real-time basis. A device
may then transmit only on those
channels which the database indicates
are available for its use. The database
system will also record registration
information from each fixed TV band
device. The registration information will
include the device’s location
(geographic coordinates) and contact
information for its user/operator. This
registration information will assist TV
band device users in coordinating
efficient use of the available television
channels at a particular location. In
addition, should any interference to
licensed services occur, the registration
information will assist in the
identification of the source of any such
interference. Finally, a TV bands
database will include provisions for
sharing registration data with any other
Commission authorized TV bands
database.
29. In considering a minimum
interval for re-contacting the database
system, it is important to note that
protection is afforded not only to TV
and other fixed facilities that do not
change often, but also to mobile/
portable facilities such as wireless
microphones. As already described, the
Commission will allow venues where
wireless microphones and other low
VerDate Nov<24>2008
16:58 Feb 13, 2009
Jkt 217001
power auxiliary devices are used on a
regular or scheduled basis to register
such usage in the TV bands database.
Because such usage could change on a
daily basis, the Commission will require
that fixed and mode II TVBDs to recheck
the database, at a minimum, on a daily
basis. Rechecking in this manner will
also provide for timely protection of
new or modified licensed facilities. This
approach accounts for the continual
changes that will occur over time as
new licenses are issued or inaccuracies
are corrected. The Commission believes
that because database access will be
performed automatically over the
Internet, rechecking the available
channels will not be burdensome. If a
device fails to contact a TV bands
database on any given day, it will be
required to cease transmitting after a
one-day grace period. That is, it must
cease operating at 11:59 PM on the day
following a day when it does not contact
a TV bands database. This grace period
will allow for situations where there has
been a sustained power loss, an Internet
outage, or other circumstances that
disrupt a device’s ability to contact a TV
bands database. In accessing a TV bands
database to update its list of available
channels, a device will only need to
provide its identification information,
current location and, for fixed devices,
any changes in its registration
information.
30. In addition to the daily database
update requirement, personal/portable
devices operating in Mode II will be
required to re-establish their location
coordinates and to access a TV bands
database for a list of available channels
each time they are activated, i.e.,
powered on, or move. If such a device
maintains a powered on state for one
day or more, the device will then be
required to re-check a TV bands
database as described above. The
Commission finds that these measures
will ensure that both fixed and
personal/portable devices properly
maintain a current list of available
channels.
31. Database information. To ensure
that a TV bands database contains
sufficient elements to both determine
available TV channels for a given
location and to register fixed TVBDs, the
Commission must define the set of data
elements for the database. The elements
for the various types of systems that will
be in the database are described herein.
Additionally, the Commission notes that
for all coordinates it will require that
they be referenced to the North
American Datum of 1983 (NAD 83) and
as described, it will require accuracy to
within 50 meters.

32. The information collected from
fixed unlicensed TV band devices will
include:
(1) FCC Identifier (FCC ID) of the
device;
(2) Manufacturer’s serial number of
the device;
(3) Device’s coordinates (latitude and
longitude);
(4) Name of the individual or business
that owns the device;
(5) Name of a contact person
responsible for the device’s operation;
(6) Address of the contact person;
(7) E-mail address of the contact
person;
(8) Phone number of the contact
person.
33. The information collected from
personal/portable unlicensed TV band
devices, which will not be registered
and only access the database for
available channels, will include:
(1) FCC Identifier (FCC ID) of the
device;
(2) Manufacturer’s serial number of
the device;
(3) Device’s coordinates (latitude and
longitude).
34. The FCC ID and serial number of
the TV band device will uniquely
identify individual fixed unlicensed TV
band devices. This information will
assist the Commission if compliance
issues concerning devices arise. A fixed
TV band device will be required to
update any information that has
changed when it makes its daily check
with a TV bands database to determine
if the list of available channels at its
location has changed. If a fixed device
does not check the database for three
months, its registration will be removed
from the database.
35. A database administrator will not
be responsible for resolving claims of
interference from TVBDs. If there is a
claim of interference, a database
administrator, upon request from the
Commission, must provide TVBD
identifying information. If a device is
found to be causing interference, the
Commission may then require that the
party responsible for the unlicensed
device take corrective actions or cease
operating the device until the
interference is resolved. In addition, if
a representative of the Commission
attempts and is unable to contact the
person responsible for a device that is
determined to be causing interference,
the Commission may require the TV
bands database to return a message of
‘‘no channels available’’ to the device at
its next scheduled re-check. This will
effectively shut down the device until
contact is made with the responsible
party so that the interference can be
resolved. The database administrator
E:\FR\FM\17FER1.SGM
17FER1
jlentini on PROD1PC65 with RULES
Federal Register / Vol. 74, No. 30 / Tuesday, February 17, 2009 / Rules and Regulations
will rescind a ‘‘no channels available’’
status for that device only upon
authorization by the Commission.
36. Now, regarding services that will
be protected, a TV bands database will
contain the following information on
full-power television stations, digital
and analog Class A stations, low-power
television stations (LPTV), television
translator stations, and television
booster stations:
(1) Transmitter coordinates (latitude
and longitude);
(2) Effective radiated power (ERP);
(3) Height above average terrain of the
transmitter (HAAT);
(4) Horizontal transmit antenna
pattern (if the antenna is directional);
(5) Channel number;
(6) Station call sign.
A TV bands database will also be
required to include data on the
distributed transmission system (DTS)
facilities of stations using that
technology and to use that data in
determining the protected service areas
of such stations. The information for full
service TV stations is available on the
Media Bureau’s Consolidated Data Base
System (CDBS).
37. A TV bands database will also
include information on Broadcast
Auxiliary Service (BAS) facilities,
which use vacant television channels
for fixed point-to-point links. For
permanent links, this information is
available from the Commission’s
Universal Licensing System (ULS). For
temporary BAS links, the party
authorized to operate the link may
voluntarily submit this information to a
TV bands database. For each BAS link
the TV bands database will contain:
(1) Transmitter coordinates (latitude
and longitude);
(2) Receiver coordinates (latitude and
longitude);
(3) Channel number;
(4) Call sign.
38. In some geographic regions,
certain television channels from
channel 14 through channel 20 are set
aside for use by PLMRS and CMRS
operations. These regions are specified
in the Commissions rules. A TV bands
database will contain the center
coordinates (latitude and longitude) for
each of these regions and the television
channels used in each region. For each
of these regions, a TV bands database
will include the following data
elements:
(1) Region name;
(2) Channel(s) reserved for use in the
region;
(3) Geographic center of the region
(latitude and longitude);
(4) Call sign.
VerDate Nov<24>2008
16:58 Feb 13, 2009
Jkt 217001
39. In addition, numerous PLMRS and
CMRS licenses have been granted in
these channels outside of the identified
geographic regions under waivers to the
Commission’s rules. These ‘‘waiver’’
licenses are specified in various ways
such as, for example, by allowing a
particular transmitted power and
antenna height for a base station at a
specified location or by specifying a
geographic area of coverage, such as the
boundaries of a local county
administrative area. The database can be
populated by information pertaining to
facilities authorized by the Commission
via an extract from the Wireless
Telecommunication Bureau’s ULS
database. This database contains
information on license holders, facility
operation parameters (frequency,
location, etc.), and any special
conditions that apply. For each of these
waiver licenses the following
information will be placed into a TV
bands database:
(1) Transmitter location (latitude and
longitude) or geographic area of
operations;
(2) Effective radiated power;
(3) Transmitter height above average
terrain (if specified);
(4) Antenna height above ground level
(if specified);
(5) Call sign.
In cases where the operator of a PLMRS/
CMRS system licensed under a waiver
operates multiple transmitters (not
including systems that are licensed to
operate in a coverage area), information
on each transmitter will be required to
be maintained in a TV bands database.
40. The Offshore Radiotelephone
Service uses channels 15–18 along the
coast of the Gulf of Mexico. The
Commission’s rules designate four
regions to protect this service. For each
of the four regions a TV bands database
will contain the following information:
(1) Geographic boundaries of the
region (latitude and longitude for each
point defining the boundary of the
region;
(2) Channel(s) used by the service in
that region.
41. As noted, cable television systems
often use antennas at their headends to
receive broadcast television signals and
then retransmit those signals to
subscriber households throughout the
cable system. In many cases, cable
systems are able to receive broadcast TV
signals at locations outside a stations’
protected service contour by using high
gain antennas mounted on top of
buildings or tall towers. Records
identifying cable systems that receive
TV stations outside of their service areas
are not currently maintained in the
PO 00000
Frm 00037
Fmt 4700
Sfmt 4700
7321
Commission’s databases. As indicated,
the Commission is extending protection
to the reception of TV signals by such
cable headends. Therefore, we are
allowing cable operators to register,
with a TV bands database, their
headends that receive TV signals
outside of a station’s protected contour
and requiring that a TV bands database
afford protection to those facilities in
accordance with the provisions
indicated. A TV bands database will
collect the following information to
register a cable headend:
(1) Name and address of cable
company;
(2) Location of the headend receiver
(latitude and longitude);
(3) Channel number of each television
channel received, subject to the
following condition: channels for which
the cable headend is located within the
protected contour of that channel’s
transmitting station are not eligible for
registration in the database;
(4) Call sign of each television
channel received and eligible for
registration;
(5) Location (latitude and longitude)
of the transmitter of each television
channel received.
42. Television translator and low
power stations, including Class A TV
stations, rebroadcast the signal of a full
service station or another low power
station. Like many cable headends, TV
translators/low power stations often
receive the signal of the station they
retransmit outside the retransmitted
station’s protected contour. The TV
translators and low power stations that
currently receive the signal they
retransmit off-the-air at locations
beyond the originating station’s
protected service contour are not
currently recorded in the Commission’s
databases. To protect the reception of
signals at the receive sites of these
stations, the Commission will allow the
licensees of such translators and low
power stations to register their receive
sites with a TV bands database and
require the database to afford those sites
protection in the same manner as
similarly situated cable headends. A TV
bands database will collect the
following information to register a
translator/low power receive site:
(1) Call sign of the TV translator or
low power TV station;
(2) Location of the TV translator or
low power station receive site (latitude
and longitude);
(3) Channel number of the
retransmitted television station, subject
to the following condition: a channel for
which the television translator receive
site is located within the protected
contour of that channel’s transmitting

station is not eligible for registration in
the database;
(4) Call sign of the retransmitted
television station;
(5) Location (latitude and longitude)
of the transmitter of the retransmitted
television station.
43. As discussed, low power auxiliary
stations such as wireless microphones
and wireless assist video devices
operate in the television bands on a
secondary basis under part 74 of the
Commission’s rules. These devices are
usually licensed to operate over a broad
geographic area and a wide range of
television channels. The use of these
devices is sometimes sporadic and
nomadic and registration of the
locations of such operations’ locations
in a TV bands database would not be
practical. However, in many cases
wireless microphones and wireless
assist video devices are used regularly
and predictably, such as at major
sporting events facilities, movie studio
lots, and television studios. For these
situations, the low power auxiliary
device users will be allowed to register
in a TV bands database, the location
where the devices are used to aid in
avoiding interference from TV band
devices. In the case of large event
facilities such as race tracks and golf
courses, the Commission will allow
multiple registrations with different
geographic coordinates to enable
protection of the entire site. The
Commission will require that requests
for registration of low power auxiliary
devices that operate on a seasonal basis,
only on certain days within a week or
only at specific times include such
information; TVBDs will be restricted
from operation in the channels used at
registered sites only on days and at
times when low power auxiliary devices
at the sites are in operation. Low power
auxiliary registrations will be valid for
no longer than a year, after which they
may be renewed. The database will
collect the following information on
registered sites that use low power
auxiliary devices:
(1) Name of the individual or business
that owns the low power auxiliary
device(s);
(2) The name of a contact person;
(3) An address for the contact person;
(4) An e-mail address for the contact
person (optional);
(5) A phone number for the contact
person (optional);
(6) Coordinates where the device(s)
are used (latitude and longitude);
(7) Channels used by the low power
auxiliary devices operated at the site;
(8) Specific months, days and times
when the device(s) are used.

44. Database Administration. The
Commission does not maintain a
database of all TV and other stations
and operations in the TV bands that
could be accessed regularly in real-time
by a large number of TVBDs dispersed
throughout the country. It will designate
one or more database administrators
from the private sector to create and
operate a TV bands database or
databases. The Commission recognizes
the interests of Google and other TVBD
proponents in ensuring that database
services be made available on a fair and
low cost (or no cost) basis and believes
that providing for authorization of more
than one party to operate a TV bands
database will serve that purpose. The
Commission will issue a public notice
requesting proposals from entities
desiring to administer a TV bands
database. Any entity that ultimately
administrators such a database must
make its services available to all TV
band device users on a nondiscriminatory basis. In addition, to
ensure stability for these new devices,
the Commission will require each
database administrator to provide
services for a five-year term, which, at
the Commission’s discretion, may be
renewed. In the event that there is only
a single a database administrator and
that entity does not wish to continue at
the end of its term, it will be required
to transfer its database along with the IP
address(es) and URL(s) used to access
the database to another designated
entity and would be allowed to charge
a reasonable price for conveyance of
that resource.
45. If the Commission chooses
multiple entities to administer TV bands
databases, it must ensure that each
database contains consistent
information so that regardless of which
database a TVBD queries, it receives the
same list of available channels in an
area. Because a TVBD will only be
required to contact a single TV bands
database, there is a need for the TV
bands databases to share accurate and
timely registration information so that
each database has a timely view of the
radio environment and can make the
best channel availability determinations
possible. Therefore, the Commission
will require that each TV bands
database, at a minimum on a daily basis,
provide to each other TV bands
database, all registration information it
receives during the previous day. This
data sharing requirement extends only
to registrations of fixed devices and
protected facilities that are not
otherwise captured in Commission
databases, including wireless
microphone and wireless assist video
PO 00000
Frm 00038

device locations, cable headends, and
TV translator/low power receive sites.
The databases can obtain information on
other services, such as full service TV,
land mobile licenses, etc. directly from
Commission databases. The
Commission believes that this sharing
requirement is extremely important to
the success of TVBDs as it decreases the
burden on any one database and also
fosters cooperation between the various
database administrators. Although, the
Commission is requiring the TV bands
databases to share information daily, it
will leave the actual implementation
details up to the database
administrators. Once the specific
entities are selected, they will need to
agree on a specific protocol and data
format requirement so that
manufacturers can build standard
devices that can work with any of the
databases and each database can easily
transmit and receive data from each
other database. In addition, the database
administrators may agree whether to
share on a more frequent timeframe than
daily.
46. A TV bands database will obtain
much of the information on licensed use
of the television bands for populating
the database from the existing
Commission databases. The TV bands
database will be required to synchronize
itself with the existing Commission
databases at least once a week so that
the information in the TV bands
database remains current. Entities
operating facilities that are entitled to
protection but that are not licensed by
the Commission, e.g., cable headends
and TV translator/low power TV station
receivers, will register their facilities
through a process established by the
database administrators. The
Commission will allow the TV bands
databases to charge fees necessary to
support the creation and operation of
the database. These fees may be
imposed on the operators of the TV
band devices for access to the database
and/or on the manufacturers of TV band
devices, but not generally on users of
the television bands who are not
currently in the Commission’s database
and desire to be included in the
database. The Commission does not
believe it is appropriate to charge
operators of licensed service for
protection of their operations from
unlicensed devices. It believes that
competition among databases will serve
to keep fees low and reasonable.
However, if parties believe that the fees
charged by a TV bands database are
excessive, they may petition the
Commission for relief.
47. The Commission recognizes that
there is potential for inaccurate

information to be entered into the
database, for omissions to occur, and for
records to be present for licensed
facilities that are no longer operating.
Such inaccuracies could be introduced
in several ways. For example, any errors
that might inadvertently be present in a
Commission database could be
transferred to a TV bands database. In
addition, the fact that we are permitting
information on certain services in the
TV bands to be voluntarily provided
introduces another potential for error.
Parties submitting such information
could inadvertently provide inaccurate
coordinates, channel or other
information, and there is also the
potential that a party could knowingly
provide false information on channel
use at a location. The database
administrators will be expected to
respond quickly to verify and/or correct
data in the event that a party brings
claims of inaccuracies in the database to
its attention, including advising the
Commission of any errors that may
appear in the Commission’s records.
Further, the Commission reserves the
right to request the removal of
voluntarily submitted information from
a TV bands database in the event that
such information is determined to be
inaccurate or not in compliance with
the rules.

Final Regulatory Flexibility Analysis
52. As required by the Regulatory
Flexibility Act (RFA),1 an Initial
Regulatory Flexibility Analysis (IRFA)
was incorporated in the Notice of
Proposed Rule Making (NPRM) in ET
Docket No. 04–186 2 and an additional
IRFA was incorporated in the First
Report and Order and Further Notice of
Proposed Rule Making (Further NPRM)
in ET Docket No. 04–186.3 The
Commission sought written public
comment on the proposals in the NPRM
and in the Further NPRM, including
comment on the IRFAs. No comments
were received in response to either
IRFA. This Final Regulatory Flexibility
Analysis (FRFA) conforms to the RFA.4
A. Need for, and Objectives of, the
Second Report and Order
53. The Second Report and Order
allows low power unlicensed
transmitters to operate in the TV
broadcast bands at locations where
spectrum is not being used by
authorized services. The new rules
provide for operation of two types of
unlicensed devices that may provide
broadband data and other types of
communications services: (1) fixed
devices, which will operate from a fixed
location with relatively higher power
and could be used to provide a variety
of services including wireless
broadband access in urban and rural
areas, and (2) personal/portable devices,
which will use lower power and could,
for example, take the form of devices
such as Wi-Fi-like cards in laptop
computers or wireless in-home local
area networks (LANs). In order to
operate without causing interference to
licensed services, both types of devices
will be required to be able to reliably
determine which channels are occupied
by licensed operations at their location
at any given time and to avoid

interfering with services on those
channels. The specific compliance
requirements are described in Section D
of this RFA.
54. The actions in this Second Report
and Order will open for use a significant
amount of spectrum with very desirable
propagation characteristics that has
heretofore lain fallow. These new rules
will allow the development of new and
innovative types of unlicensed devices
that provide broadband data and other
services for businesses and consumers
without disrupting the incumbent
television and other authorized services
that operate in the TV bands. In
addition, because transmissions on
frequencies in the TV bands are less
subject to propagation losses than
transmissions in the spectrum bands
where existing low power broadband
unlicensed operations are permitted,
i.e., the 2.4 GHz and 5 GHz bands, the
Commission anticipates that allowing
unlicensed operation in the TV bands
will benefit wireless internet service
providers (WISPs) by extending the
service range of their operations. This
will allow wireless broadband providers
that use unlicensed devices to reach
new customers and to extend and
improve their services in rural areas.
The Commission anticipates that
allowing use of the TV white spaces by
unlicensed devices will have significant
benefits for both businesses and
consumers and thereby promote more
efficient and effective use of the TV
spectrum.
B. Summary of Significant Issues Raised
by Public Comments in Response to the
IRFA
55. No comments were received in
response to either the IRFA in the
NPRM or the IRFA in the Further NPRM.
C. Description and Estimate of the
Number of Small Entities to Which
Rules Will Apply
56. The RFA directs agencies to
provide a description of, and, where
feasible, an estimate of, the number of
small entities that may be affected by
the rules adopted herein.5 The RFA
generally defines the term ‘‘small
entity’’ as having the same meaning as
the terms ‘‘small business,’’ ‘‘small
organization,’’ and ‘‘small governmental
jurisdiction.’’ 6 In addition, the term
‘‘small business’’ has the same meaning
as the term ‘‘small business concern’’

‘‘small business concern’’ is one which:
(1) Is independently owned and
operated; (2) is not dominant in its field
of operation; and (3) satisfies any
additional criteria established by the
Small Business Administration (SBA).8
57. Radio and Television
Broadcasting and Wireless
Communications Equipment
Manufacturing. The Census Bureau
defines this category as follows: ‘‘This
industry comprises establishments
primarily engaged in manufacturing
radio and television broadcast and
wireless communications equipment.
Examples of products made by these
establishments are: transmitting and
receiving antennas, cable television
equipment, GPS equipment, pagers,
cellular phones, mobile
communications equipment, and radio
and television studio and broadcasting
equipment.’’ 9 The SBA has developed a
small business size standard for Radio
and Television Broadcasting and
Wireless Communications Equipment
Manufacturing, which is: all such firms
having 750 or fewer employees.10
According to Census Bureau data for
2002, there were a total of 1,041
establishments in this category that
operated for the entire year.11 Of this
total, 1,010 had employment of under
500, and an additional 13 had
employment of 500 to 999.12 Thus,
under this size standard, the majority of
firms can be considered small.
58. Wireless Service Providers. The
SBA has developed a small business
601(3), the statutory definition of a small business
applies ‘‘unless an agency, after consultation with
the Office of Advocacy of the Small Business
Administration and after opportunity for public
comment, establishes one or more definitions of
such term which are appropriate to the activities of
the agency and publishes such definition(s) in the
Federal Register.’’

‘‘establishments’’ is a less helpful indicator of small
business prevalence in this context than would be
the number of ‘‘firms’’ or ‘‘companies,’’ because the
latter take into account the concept of common
ownership or control. Any single physical location
for an entity is an establishment, even though that
location may be owned by a different establishment.
Thus, the numbers given may reflect inflated
numbers of businesses in this category, including
the numbers of small businesses. In this category,
the Census breaks-out data for firms or companies
only to give the total number of such entities for
2002, which was 929.

size standard for wireless firms within
the two broad economic census
categories of ‘‘Paging’’ 13 and ‘‘Cellular
and Other Wireless
Telecommunications.’’ 14 Under both
categories, the SBA deems a wireless
business to be small if it has 1,500 or
fewer employees. For the census
category of Paging, Census Bureau data
for 2002 show that there were 807 firms
in this category that operated for the
entire year.15 Of this total, 804 firms had
employment of 999 or fewer employees,
and three firms had employment of
1,000 employees or more.16 Thus, under
this category and associated small
business size standard, the majority of
firms can be considered small. For the
census category of Cellular and Other
Wireless Telecommunications, Census
Bureau data for 2002 show that there
were 1,397 firms in this category that
operated for the entire year.17 Of this
total, 1,378 firms had employment of
999 or fewer employees, and 19 firms
had employment of 1,000 employees or
more.18 Thus, under this second
category and size standard, the majority
of firms can, again, be considered small.
D. Description of Projected Reporting,
Recordkeeping, and Other Compliance
Requirements
59. Unlicensed transmitters are
currently required to be authorized
under the Commission’s certification
procedure as a prerequisite to marketing
and importation, and TV band devices
would be subject to a certification
requirement. The existing certification
procedure in the Commission’s rules
will be used for TV band devices, except
that TV band devices that rely on
spectrum sensing as the sole method of
determining whether a channel is
available will have additional
certification requirements which are
described below. The compliance
requirements for TV band devices are as
follows.

60. The purpose of the TV bands
database system for fixed and Mode II
personal/portable devices is to identify
all services in the TV bands that are
eligible for protection. A TV band
device will send its geographic
coordinates to the database, which will
return a list of channels available at that
location. The Commission will issue a
Public Notice to solicit interested
parties in administering the database.

The database will contain information
about licensed services operating in the
TV bands obtained from the
Commission’s databases, including full
service and low power TV stations,
Broadcast Auxiliary Service (BAS) links,
and PLMRS operations under waivers.
In addition, the database will contain
voluntarily submitted information on
services in the TV bands that are either
not in the Commission’s databases or
are not licensed by specific coordinates,
such as wireless microphones.
61. The Second Report and Order
provides for certification of devices that
rely on sensing alone based on a proof
of performance standard. The
manufacturer may submit an
application for certification of a device
that meets all of the requirements for a
TV band device except for geo-location
and database access. The application
would be available to the public, except
for information that may qualify as a
trade secret under our rules. A fully
functioning pre-production prototype
would need to be submitted to the
Commission for laboratory and field
testing. The testing will be open to the
public. The determination of whether to
certify the equipment will depend on
whether the device is shown to provide
a high level of confidence that it will
not interfere with incumbent radio
services. It must perform at least as well
as a device that uses geo-location and
database access for interference
avoidance. Once a device is certified
under these provisions, the Commission
would certify other devices that are
electrically identical under the usual
certification process.
62. The Second Report and Order
imposes new reporting requirements on
parties operating fixed TV band devices.
Operators of fixed TV band devices will
be required to register their location and
information about the operator with a
TV bands database. When a fixed TV
band device queries the database the
first time, the device will be registered
in the database system. Operators of
fixed TV band devices must supply the
following registration information and
update this information, as necessary,
when performing the daily database
queries to verify continued channel
availability. The Commission may ask a
database administrator for this
information in the event that a device is
found to be causing interference.
(1) FCC identifier (FCC ID) of the
device.
(2) Manufacturer’s serial number of
the device.
(3) Device’s coordinates (latitude and
longitude accurate to within 50 m).

(4) Name of the entity, whether an
individual or business, responsible for

(5) Name of a contact person
responsible for the device’s operation.
(6) Address for the contact person.
(7) E-mail address for the contact
person.
(8) Phone number for the contact
person.
63. As noted in the Second Report
and Order, the Commission’s Office of
Engineering and Technology will
designate a party or parties to
administer the database of authorized
services in the TV bands. Much of this
information will be obtained from the
Commission’s databases, including
information on full service and low
power TV stations, Broadcast Auxiliary
Service (BAS) links, and PLMRS
operations under waivers. However, the
database will also contain information
submitted voluntarily by parties
operating services in the TV bands that
are either not listed in the Commission’s
databases or are not licensed by specific
coordinates. These services include BAS
links authorized on a temporary basis,
receive sites for TV translators and cable
TV systems, and sites where wireless
microphones are used regularly and
predictably, such as major sporting
events. The purpose of this voluntarily
submitted information is to prevent TV
band devices from causing interference
to services that do not appear in the
Commission’s database. The submission
of such information is strictly voluntary,
but services operated by parties that do
not submit this information may not be
protected against interference from TV
band devices.
E. Steps Taken To Minimize Significant
Economic Impact on Small Entities and
Significant Alternatives Considered
64. The RFA requires an agency to
describe any significant alternatives that
it has considered in developing its
approach, which may include the
following four alternatives (among
others): ‘‘(1) The establishment of
differing compliance or reporting
requirements or timetables that take into
account the resources available to small
entities; (2) the clarification,
consolidation, or simplification of
compliance and reporting requirements
under the rule for such small entities;
(3) the use of performance rather than
design standards; and (4) an exemption
from coverage of the rule, or any part
thereof, for such small entities.’’ 19
65. The rules adopted in the Second
Report and Order may have a significant
economic impact on a substantial
number of small entities. For an entity
that chooses to manufacture or import
equipment for the subject bands, the
rules would impose costs for
compliance with equipment technical
requirements. The costs for fixed and
Mode II personal/portable devices
include incorporating a geo-location
method to determine the geographic
coordinates and the ability to access a
database of authorized services in the
TV bands, for which a fee may be
charged by the database administrator.
The costs for all TV band devices
include incorporating the ability to
detect TV and wireless microphone
signals. However, the burdens for
complying with these rules would be
the same for both large and small
entities. Therefore, no disproportionate
burden of compliance would be
sustained by small entities. Further, the
rules adopted in the Second Report and
Order are ultimately beneficial for both
large and small entities because they
will provide for more efficient and
effective use of the TV spectrum and
allow the development of new and
innovative types of wireless devices and
communication services for businesses
and consumers. Also, because
transmissions in the TV band are subject
to less propagation attenuation than
transmissions in other bands where
lower power operations are permitted
(such as unlicensed operations in the
2.4 GHz band), operations in the TV
bands can improve the service range of
wireless operations, thereby allowing
operators to reach new customers.
F. Report to Congress
66. The Commission will send a copy
of the Second Report and Order,
including this FRFA, in a report to be
sent to Congress pursuant to the
Congressional Review Act.20 In
addition, the Commission will send a

jlentini on PROD1PC65 with RULES
§ 15.709
General technical requirements.
(a) Power limits for TVBDs are as
follows: (1) For fixed TVBDs, the
maximum conducted output power over
the TV channel of operation shall not
exceed one watt. Transmitter power will
be measured at the antenna input to
account for any cable losses between the
transmitter and the antenna. If
transmitting antennas of directional gain
greater than 6 dBi are used, the
maximum conducted output power
shall be reduced by the amount in dB
that the directional gain of the antenna
exceeds 6 dBi.
(2) For personal/portable TVBDs, the
maximum conducted output power over
the TV channel of operation shall not
exceed 100 milliwatts; except that for
personal/portable TVBDs that do not
meet the adjacent channel separation
requirements in § 15.712(a), the
maximum conducted output power
shall not exceed 40 milliwatts. If
transmitting antennas of directional gain
greater than 0 dBi are used, the
maximum conducted output power
shall be reduced by the amount in dB
that the directional gain of the antenna
exceeds 0 dBi.
(3) TVBDs shall incorporate transmit
power control to limit their operating
power to the minimum necessary for
successful communication. Applicants
for certification shall include a
description of a device’s transmit power
control feature mechanism.
(4) Maximum conducted output
power is the total transmit power in the
entire emission bandwidth delivered to
all antennas and antenna elements
averaged across all symbols in the
signaling alphabet when the transmitter
VerDate Nov<24>2008
16:58 Feb 13, 2009
Jkt 217001
is operating at its maximum power
control level. Power must be summed
across all antennas and antenna
elements. The average must not include
any time intervals during which the
transmitter is off or is transmitting at a
reduced power level. If multiple modes
of operation are possible (e.g.,
alternative modulation methods), the
maximum conducted output power is
the highest total transmit power
occurring in any mode.
(b) Antenna requirements. (1) For
personal/portable TVBDs, the antenna
shall be permanently attached.
(2) The receive antenna used with
fixed devices shall be located outdoors
at least 10 meters above the ground. The
antenna system shall be capable of
receiving signals of protected services
equally in all directions. The transmit
antenna used with fixed devices may
not be more than 30 meters above the
ground.
(3) For both fixed and personal/
portable TVBDs, the provisions of
§ 15.204(c)(4) do not apply to an
antenna used for transmission and
reception/spectrum sensing.
(4) For both fixed and personal/
portable TVBDs with a separate sensing
antenna, compliance testing shall be
performed using the lowest gain
antenna for each type of antenna to be
certified.
(c) Undesirable emission limits for
TVBDs are as follows:
(1) In the 6 MHz channels adjacent to
the operating channel, emissions from
TVBD devices shall be at least 55 dB
below the highest average power in the
band in which the device is operating.
(2) The above emission measurements
shall be performed using a minimum
resolution bandwidth of 100 kHz with
an average detector. A narrower
resolution bandwidth may be employed
near the band edge, when necessary,
provided the measured energy is
integrated to show the total power over
100 kHz.
(3) At frequencies beyond 6 MHz from
the edge of the operating channel,
radiated emissions from TVBD devices
shall meet the requirements of § 15.209.
(4) Emissions in the band 602–620
MHz must also comply with the
following field strength limits at a
distance of one meter.

(5) TVBDs connected to the AC power
line are required to comply with the
conducted limits set forth in § 15.207.
(d) Compliance with radio frequency
exposure requirements. To ensure
compliance with the Commission’s
radio frequency exposure requirements
in §§ 1.1307(b), 2.1091 and 2.1093 of
this chapter, fixed TVBDs shall be
accompanied by instructions on
measures to take to ensure that persons
maintain a distance of at least 40 cm
from the device, as well as any
necessary hardware that may be needed
to implement that protection. These
instructions shall be submitted with the
application for certification. Personal/
portable TVBDs that meet the definition
of portable devices under § 2.1093 of
this chapter and that operate with a
source-based time-averaged output of
less than 20 mW will not be subject to
routine evaluation for compliance with
the radio frequency exposure
guidelines, while devices that operate
with a source-based time-average output
power greater than 20 mW will be
subject to the routine evaluation
requirements.
§ 15.711 Interference avoidance
mechanisms.
(a) Except as provided in § 15.717,
television channel availability for a
TVBD is determined based on either the
geo-location and database access
mechanism described in paragraph (b)
of this section or spectrum sensing
described in paragraph (c) of this
section.
(1) A TVBD shall rely on the geolocation and database access mechanism
to identify available television channels
consistent with the interference
protection requirements of § 15.712.
Such protection will be provided for the
following authorized services: digital
television stations, digital and analog
Class A, low power, translator and
booster stations; translator receive
operations; fixed broadcast auxiliary
service links; private land mobile
service/commercial radio service
(PLMRS/CMRS) operations; offshore
radiotelephone service; and cable
system head-ends. In addition,
protection shall be provided in border
areas near Canada and Mexico in
accordance with § 15.712(g).
(2) For low power auxiliary services
authorized pursuant to §§ 74.801
through 74.882 of this chapter,
including wireless microphones, a
TVBD shall rely on the geo-location and
database access mechanism to identify
available television channels to provide
interference protection to registered
locations of such operations, consistent
with the requirements of § 15.712, and
E:\FR\FM\17FER1.SGM
17FER1
jlentini on PROD1PC65 with RULES
7328
Federal Register / Vol. 74, No. 30 / Tuesday, February 17, 2009 / Rules and Regulations
shall rely on spectrum sensing to
identify available television channels to
provide interference protection to all
other operations.
(b) Geo-location and database access.
(1) The geographic coordinates of a
fixed TVBD shall be determined to an
accuracy of +/¥50 meters by either an
incorporated geo-location capability or a
professional installer. In the case of
professional installation, the party who
registers the fixed TVBD in the database
will be responsible for assuring the
accuracy of the entered coordinates. The
geographic coordinates of a fixed TVBD
shall be determined at the time of
installation and first activation from a
power-off condition, and this
information may be stored internally in
the TVBD. If the fixed TVBD is moved
to another location or if the stored
coordinates become altered, the operator
shall re-establish the device’s:
(i) Geographic location and store this
information in the TVBD either by
means of the device’s incorporated geolocation capability or through the
services of a professional installer; and
(ii) Registration with the database
based on the device’s new coordinates.
(2) A Mode II personal/portable
device shall incorporate a geo-location
capability to determine its geographic
coordinates to an accuracy of +/¥50
meters. The device must re-establish its
position each time it is activated from
a power-off condition.
(3)(i) Fixed devices must access a TV
bands database over the Internet to
determine the TV channels that are
available at their geographic coordinates
prior to their initial service transmission
at a given location. Operation is
permitted only on channels that are
indicated in the database as being
available for TVBDs. Fixed TVBDS shall
access the database at least once a day
to verify that the operating channels
continue to remain available. Operation
must cease immediately if the channel
is no longer available.
(ii) Mode II personal/portable devices
must access a TV bands database over
the Internet to determine the TV
channels that are available at their
geographic coordinates prior to their
initial service transmission at a given
location. Operation is permitted only on
channels that are indicated in the
database as being available for TVBDs.
A Mode II personal/portable device
must access the database for a list of
available channels each time it is
activated from a power-off condition
and re-check its location and the
database for available channels if it
changes location during operation. A
Mode II personal/portable device that
has been in a powered state shall re-
VerDate Nov<24>2008
16:58 Feb 13, 2009
Jkt 217001
check its location and access the
database daily to verify that the
operating channel(s) continue to be
available.
(iii) If a fixed or mode II TVBD fails
to contact the TV bands database during
any given day, it may continue to
operate until 11:59 PM of the following
day at which time it must cease
operations unless it has contacted the
TV bands database during the
intervening period.
(iv) Personal/portable devices
operating in Mode I shall obtain a list
of channels on which they may operate
from a master device.
(4) All geographic coordinates shall be
referenced to the North American
Datum of 1983 (NAD 83).
(c) Spectrum sensing.
(1) Detection threshold.
(i) All fixed and personal/portable
TVBDs must be capable of detecting
ATSC digital TV, NTSC analog TV and
wireless microphone signals using
analog or digital modulation methods.
The required detection thresholds are.
(A) ATSC signals: ¥114 dBm,
averaged over a 6 MHz bandwidth;
(B) NTSC signals: ¥114 dBm,
averaged over a 100 kHz bandwidth;
(C) Wireless microphone signals:
¥114 dBm, averaged over a 200 kHz
bandwidth. (ii) The detection thresholds
are referenced to an omnidirectional
receive antenna with a gain of 0 dBi. If
a receive antenna with a minimum
directional gain of less than 0 dBi is
used, the detection threshold shall be
reduced by the amount in dB that the
minimum directional gain of the
antenna is less than 0 dBi. Minimum
directional gain shall be defined as the
antenna gain in the direction and at the
frequency that exhibits the least gain.
Alternative approaches for the sensing
antenna are permitted, e.g.,
electronically rotateable antennas,
provided the applicant for equipment
authorization can demonstrate that its
sensing antenna provides at least the
same performance as an omnidirectional
antenna with 0 dBi gain.
(2) Low power auxiliary device
channel availability check time. A
TVBD may start operating on a TV
channel if no wireless microphone or
other low power auxiliary device signals
above the detection threshold are
detected within a minimum time
interval of 30 seconds.
(3) TV channel availability check
time. A TVBD is required to check for
TV signals for a minimum time interval
of 30 seconds. If a TV signal is detected
on a channel indicated as available for
use by the database system, the device
will provide a notice of that detection to
the operator of the device and a means
PO 00000
Frm 00044
Fmt 4700
Sfmt 4700
for the operator to optionally remove the
channel from the device’s list of
available channels.
(4) In-service monitoring. A TVBD
must perform in-service monitoring of
an operating channel a minimum of
once every 60 seconds. There is no
minimum channel availability check
time for in-service monitoring.
(5) Channel move time. After a
wireless microphone or other low power
auxiliary device signal is detected on a
TVBD operating channel, all
transmissions by the TVBD must cease
within two seconds.
(6) Personal/portable devices
operating in the client mode shall
identify to the fixed or Mode II
personal/portable device those
television channels on which it senses
any signals above the detection
threshold. The fixed or Mode II device
shall respond in accordance with the
provisions of this paragraph as if it had
detected the signal itself.
(7) TVBDs communicating either
directly with one another or linked
through a base station must share
information on channel occupancy
determined by sensing. If any device in
a local area group or network
determines that a channel is occupied,
all other linked devices will also be
required to respond in accordance with
the provisions of this paragraph as if it
had detected the signal itself.
(d) A TVBD must incorporate the
capability to display a list of identified
available channels and its operating
channels.
(e) Fixed TVBDs shall transmit
identifying information. The
identification signal must conform to a
standard established by a recognized
industry standards setting organization.
The identification signal shall carry
sufficient information to identify the
device and its geographic coordinates.
(f) If a fixed TVBD device does not
have a direct connection to the Internet
and has not yet been initialized and
registered with the TV bands database,
consistent with § 15.713, but can receive
the transmissions of another fixed
TVBD, the device needing initialization
may transmit to that other device on
either a channel that the other TVBD
has transmitted on or on a channel
which the other TVBD indicates is
available for use to access the database
to register its location and receive a list
of channels that are available for it to
use. Subsequently, the newly registered
TVBD must only use the television
channels that the database indicates are
available for it to use. Such fixed
devices must re-contact the database
through another fixed device to review
their list of available channels at least
E:\FR\FM\17FER1.SGM
17FER1
Federal Register / Vol. 74, No. 30 / Tuesday, February 17, 2009 / Rules and Regulations
once every 60 seconds. A fixed device
may not operate as a client to another
fixed device.
(g) A personal/portable TVBD
operating in Mode I may only transmit
upon receiving the transmissions of
fixed or Mode II TVBD. A personal/
portable device operating in Mode I may
transmit on either an operating channel
of the fixed or Mode II TVBD or on a
channel the fixed or Mode II TVBD
indicates is available for use.

TV bands database.
(a) Purpose. The TV bands database
serves the following functions:
(1) To determine and provide to a
TVBD, upon request, the available TV
channels at the TVBD’s location.
Available channels are determined
based on the interference protection
requirements in § 15.712.
(2) To register the identification
information and location of fixed
TVBDs.
(3) To register protected locations and
channels as specified in paragraph (b)(2)
of this section, that are not otherwise
recorded in Commission licensing
databases.
(b) Information in the TV bands
database. (1) Facilities already recorded
in Commission databases. Identifying
and location information will come
from the official Commission database.
These services include:
(i) Digital television stations.
(ii) Class A television stations.
(iii) Low power television stations.
(iv) Television translator and booster
stations.
(v) Broadcast Auxiliary Service
stations (including receive only sites),
except low power auxiliary stations.
(vi) Private land mobile radio service
stations.
(vii) Commercial mobile radio service
stations.
(viii) Offshore radiotelephone service
stations.

Summary of the Report and Order and Memorandum Opinion and Order
1. On May 13, 2004, the Commission adopted a Notice of Proposed
Rule Making (NPRM), 71 FR 66897, November 17, 2006, in this proceeding
in which it proposed to allow unlicensed operation in the TV bands at
locations where frequencies are not in use by licensed services. To
ensure that no harmful interference will occur to TV stations and other
authorized users of the spectrum, the Commission proposed to define the
conditions under which a TV channel is unused and to require unlicensed
devices to incorporate ``smart radio'' features to identify the unused
TV channels in the area where they are located. For the purpose of
minimizing interference, the Commission proposed to classify unlicensed
TVBDs in two general functional categories. The first category would
consist of lower power ``personal/portable'' unlicensed devices, such
as Wi-Fi-like cards in laptop computers or wireless in-home local area
networks (LANs). The second category would consist of higher power
``fixed'' unlicensed devices that would operate from a fixed location
and could be used to provide commercial services such as wireless
broadband Internet access. It proposed to require that personal/
portable devices operate only when they receive a control signal from a
source such as a TV station or FM radio station that identifies the
vacant TV channels in that particular area. The Commission also
requested comments on an approach that would require that fixed devices
incorporate a geo-location method such as a Global Positioning System
(GPS) receiver or be professionally installed, and that they access a
database system to identify vacant channels at their location. The
Commission further sought comment on the use of spectrum sensing to
identify vacant TV channels, but did not propose any specific technical
criteria for spectrum sensing.
2. The comments received in response to the NPRM were divided
between the prospective manufacturers and users of unlicensed devices
who believe adequate safeguards can be put in place to prevent harmful
interference to authorized services, and the existing users of the TV
bands who are concerned about potential interference. A number of
broadband equipment manufacturers, trade associations and other parties
supported allowing unlicensed operation in the TV bands. These parties
generally stated that unlicensed devices could operate in the TV bands
without causing interference to authorized services. They further
stated that allowing such operation in the TV bands could improve
access to broadband communications by taking advantage of the favorable
propagation characteristics of the TV spectrum and that this would
result in more efficient use of this spectrum.
3. Full service and low power TV broadcasters generally opposed
allowing unlicensed operation in the TV bands, expressing concern that
unlicensed devices operating under the proposed rules would cause
interference to TV reception, particularly in weak signal areas.
Several parties also expressed concern that unlicensed devices
operating in close proximity to TV receivers would cause direct pick-up
interference potentially affecting all channels. Manufacturers and
users of wireless microphones and other broadcast auxiliary services
submitted that unlicensed devices would cause harmful interference to
those services. Those parties recommended that the Commission take a
number of steps to protect auxiliary services. Land mobile interests
expressed concern about allowing unlicensed operation on channels 14-20
in any part of the country because devices could be transported into
areas where those channels are used for PLMRS/CMRS operations.
4. On October 12, 2006, the Commission adopted the First R&O/
Further NPRM, 71 FR 66897, November 17, 2006, in this proceeding. In
that action, the Commission determined that the record received in
response to the NPRM did not contain sufficient information for it to
adopt final rules for unlicensed TVBDs. The Commission did, however,
make a number of initial decisions regarding TVBDs. It decided to
permit fixed unlicensed power devices to operate in the TV bands at
times and locations where the spectrum is not already being used by
other authorized services. It also decided not to permit operation of
unlicensed TVBDs on channel 37, which is used by radio astronomy and
wireless medical telemetry services, and on TV channels 52-69, as that
spectrum has been reallocated for other services and will no longer be
part of the TV bands after the DTV transition. The Commission further
decided to prohibit operation of personal/portable TV band devices on
TV channels 14-20 to avoid potential conflicts with public safety
services on those channels. In addition, the
[[Page 7316]]
Commission stated that it will not permit marketing of TV band devices
to commence until February 18, 2009, the date on which all primary,
full service TV stations will be in operation on their permanent DTV
channels.
5. In the First R&O/Further NPRM, the Commission also asked
questions and set forth additional proposals with regard to the
provisions necessary to implement complete and final rules for
unlicensed TV band devices. While the Commission continued to focus on
devices operating on an unlicensed basis, it also sought comment on
whether such devices should instead operate on a licensed or hybrid
basis. The Commission recognized the importance of conducting testing
to ensure that whatever standards are ultimately adopted will protect
incumbent radio services from interference and indicated that it
intended to conduct extensive testing to assess the potential
interference from low power devices operating in the TV bands. It also
requested further comment and information on the means that TVBDs, both
fixed and personal/portable, should be required to use to determine the
availability of unused spectrum. It specifically requested comment on
whether it should allow personal/portable devices to rely on spectrum
sensing and, if so, the technical features and parameters of the
sensing capability to be required. The Commission observed that IEEE
802.22 is considering different sensing threshold detection levels
depending on the nature of the source signal, with levels as low as -
116 dBm, and invited comment on this value or alternative values for
the detection threshold. It also made specific proposals for additional
parameters of spectrum sensing capabilities and other technical
requirements. The Commission sought comment on whether TV band devices
should be permitted to operate on TV channels 2-4, and whether fixed TV
band devices should be permitted to operate on TV channels 14-20. The
Commission also sought additional comments on several issues relating
to the geo-location/database access and control signal approaches
discussed in the NPRM.
6. The comments responding to the First R&O/Further NPRM are again
divided on certain of the major issues in this proceeding. Two groups,
one a coalition of hardware and software companies consisting of Dell,
Google, HP, Intel, Microsoft and Phillips (the White Space Coalition)
and the other a group of public interest/consumer organizations and
wireless internet service providers (WISPs), led by the NAF, strongly
support low power, unlicensed use of the TV bands. In addition, some
other manufacturers and a number of WISPs express support for that
approach separately from these groups. Proponents of unlicensed devices
believe that the Commission should allow both fixed and personal/
portable devices. They also support allowing personal/portable devices
to rely solely on spectrum sensing to determine the available channels
at their location. The White Space Coalition supports limiting
unlicensed operation to channels 21-51 (excluding 37), while the group
led by the NAF believes that operation should be permitted on as many
channels as possible, including channels 2-4 and channels 14-20 in
locations where public safety and land mobile services are not using
them.
7. Full service and low power TV broadcasters and cable TV
interests generally state that any new services in the TV bands should
be licensed to reduce the likelihood of interference to incumbent
services. They oppose the introduction of personal/portable devices at
this time and believe that any new services should be limited to fixed
operation. Broadcasters contend that spectrum sensing alone is
inadequate to protect against interference to broadcast operations and
that sensing must be combined with geo-location/database access to
ensure that low power devices do not operate inside the protected
service contours of co-channel or adjacent-channel TV stations. Low
power TV and translator operators express concern that low power
unlicensed devices would cause interference to viewers who rely on
reception outside their stations' protected service contours, while
cable interests express concern about possible interference to
reception of TV signals by cable headends that are located outside TV
stations' protected contours. Both broadcast and cable interests
express concern about direct pick-up interference to TV receivers,
particularly from personal/portable devices.
8. Wireless microphone manufacturers and users again recommend that
the Commission adopt a number of requirements to prevent interference
to wireless microphones, including: (1) Limiting new low power devices
to fixed operation, (2) prohibiting new low power devices from
operating on channels adjacent to occupied TV channels and/or reserving
six vacant TV channels in each market for wireless microphones to
ensure that spectrum is available for their use, (3) requiring new low
power devices to incorporate spectrum sensing to detect wireless
microphones, and (4) requiring new low power devices to sense for the
presence of a ``smart beacon'' that would be operated when wireless
microphones are in use in an area (Shure has since repudiated its
support for a beacon requirement). Public safety/land mobile interests
believe that new low power devices should not be allowed to operate on
channels 14-20 anywhere in the country because of the difficulties in
enforcing geographic restrictions on operation.
9. On March 30, 2007, the Commission's Office of Engineering and
Technology released a report on the results of its DTV receiver testing
program, see DA 07-3457, 22 FCC Rcd 13846 (2007). This testing program
examined the out-of-channel interference rejection performance of a
representative sample of eight DTV receivers with fifth generation
tuners that were available in 2005 and 2006. A total of 2055 individual
measurements were performed on these receivers. Each test involved
feeding a desired signal to the television under test and injecting an
interfering signal on a different channel or combination of channels.
The different tests varied the level of the desired signal and
interfering signal(s). In these tests, no receiver appeared to fully
achieve the Advanced Television Systems Committee's (ATSC) recommended
guidelines for interference rejection performance--guidelines that are
generally more stringent than the receiver performance assumptions on
which current DTV interference protection criteria are based. However,
the tests did show that the performance of digital television receivers
exceeds the performance levels on which the Commission's digital
television service and interference rules are based.
10. On July 31, 2007, the Office of Engineering and Technology
released a technical report on an initial study of prototype TV band
devices that were submitted to the Commission's Laboratory for testing.
This report evaluated the performance of two samples of prototype
devices; one device had both sensing and transmitting capabilities
(although the two functions were not linked) and the other had only
sensing capability. This testing found that one of the two devices was
generally able to reliably detect TV signals in the laboratory bench
tests at the claimed -114 dBm sensing level, but did not perform well
sensing wireless microphones. This device was not tested in the field
at the manufacturer's request. The other device was not able to
reliably sense either TV or wireless microphone
[[Page 7317]]
signals at the -114 dBm level in either the Laboratory bench tests or
in field tests. The builder of this device subsequently determined that
the device's sensing function was not operating properly. In an
anecdotal observation, the transmitter of the second device was found
to cause co-channel and adjacent channel interference to TV service at
distances of 87 meters and 47-50 meters, respectively.
11. Also on July 31, 2007, the Office of Engineering and Technology
released a second technical report describing direct pick-up
interference tests of three digital cable ready television receivers.
In these tests, three digital cable ready (DCR) receivers connected
directly to cable service were examined for their susceptibility to
interference from devices such as might operate within the TV white
spaces. Tests were performed with the interfering signal source
separated from the DCR receiver by distances of 2 meters or ten meters
and, in most observations, by a residential wall. These tests showed
that a signal as low as 6.3 dBm EIRP could cause interference at a
distance of two meters and that a signal as low as 15.3 dBm could cause
interference at a distance of 10 meters. While these tests were limited
in scope (only three receivers were tested), they nonetheless provide
an empirical demonstration of the potential for such interference at
relatively low power levels.
12. On October 15, 2008, the Office of Engineering and Technology
issued a technical report on a second phase of its study of sample
prototype TV band devices. This second phase study examined the
performance of prototype devices from five parties. All of these
devices had capabilities for sensing TV signals, three had capabilities
for sensing wireless microphones and one (that of Adaptrum) had a
transmit capability (this transmit capability was not linked to the
device's sensing capabilities). One of the devices (that of Motorola)
also had a geolocation/ database access capability.
13. In the laboratory tests of TV signals, the Phase II prototype
devices were able to detect a ``clean,'' i.e., unfaded, DTV signal on a
single channel at levels in the range of -116 dBm to -126 dBm. The
detection threshold sensitivity of the devices varied from -106 dBm to
-128 dBm when recorded off-air DTV signals, which included multi-path
fading and other ``real-world'' distortion, were used. When the devices
were tested with DTV signals present in adjacent channels, the staff
found that in the presence of moderate-to-strong signals in a first
adjacent channel, the detection threshold sensitivity of all of the
devices was severely impacted. For some of the devices, the degradation
in the detection sensitivity was as much as 60-70 dB. In some cases,
the degradation was such that the detection threshold could not be
measured. The Phase II Measurement Report indicates that this could
impact significantly the ability of the devices to reliably detect TV
signals within stations' service areas.
14. TV sensing field tests were performed at nine locations with
four of the prototype devices. In most cases, the devices correctly
reported channels as occupied when the device was operated within the
service contour of the stations broadcasting on those channels and
viewable signals were observed on the channels. In some instances,
however, three of the devices incorrectly reported channels as
unoccupied (available) when the device was operated within a station's
service contour and the signal was viewable. All of the devices
reported some channels as occupied when the WSD was operated outside of
the service contours of stations broadcasting on those channels whether
the signal was viewable or not. In addition, one device generally
reported most channels occupied, whether the device was operating
inside or outside any service contours and whether the signal was
viewable or not. During the field tests, the Motorola device's
geolocation/database access feature was used in combination with its
sensing capabilities. In those tests, the Motorola device correctly
reported all occupied channels used by stations within whose contours
the WSD was operated.
15. The second phase study also examined the ability of devices to
sense wireless microphones designed to operate under part 74 of our
rules. The two operating devices with wireless microphone sensing
capability, those of Philips and I2R, were tested in the laboratory for
their ability to detect wireless microphones (models using both FM/
analog and digital) operating within UHF TV channels. With no other
signals present, the devices were able to detect wireless microphones
at levels ranging from -103 dBm to -129 dBm depending on the type of
microphone, and the device. However, in the presence of DTV signals in
adjacent channels, the detection threshold of both devices was degraded
such that it affected the ability of the devices to reliably detect the
microphone signals.
16. Finally, the second phase study conducted tests with the
Adaptrum device's transmitter. The device's transmitter was
characterized in the laboratory and then used to investigate
interference potential to DTV signal reception. Anecdotal tests
demonstrated that co-channel interference would occur at line-of-sight
distances of up to 360 meters at an EIRP level of approximately +7 dBm
when the DTV set was receiving a weak signal off-the-air using a
receive antenna at a height of 9.3 meters. No interference was observed
when the device transmitted on an immediate adjacent channel even with
the transmitter in close proximity to the receiver with a roof-top
antenna. No other configurations were tested for interference.
Anecdotal tests with the Adaptrum transmitter were performed at two
field sites to assess the interference potential from a TVBD
transmitter to cable television reception via direct pick-up of signals
by cable system components. These tests showed that under certain
circumstances, when the transmit antenna was placed in close proximity
to a cable connected TV, direct pick-up interference occurred. The
report indicated that the direct pick-up interference potential appears
to be highly dependent on the interconnection among the various receive
system components (e.g., cable amplifiers, splitters and set-top boxes)
being used.
17. In the Second Report and Order, the Commission adopted rules to
allow unlicensed radio transmitters to operate in the broadcast
television spectrum at locations where that spectrum is not being used
by licensed services (this unused TV spectrum is often termed ``white
spaces''). This action will open for use a significant amount of
spectrum with very desirable propagation characteristics that has
heretofore lain fallow. These new rules will allow the development of
new and innovative types of unlicensed devices that provide broadband
data and other services for businesses and consumers without disrupting
the incumbent television and other authorized services that operate in
the TV bands. In addition, because transmissions on frequencies in the
TV bands are less subject to propagation losses than transmissions in
the spectrum bands where existing low power broadband unlicensed
operations are permitted, i.e., the 2.4 GHz and 5 GHz bands, the
Commission anticipates that allowing unlicensed operation in the TV
bands will benefit wireless Internet service providers (WISPs) by
extending the service range of their operations. This will allow
wireless broadband providers that use unlicensed devices to reach new
customers and to extend and improve their services in rural areas. We
[[Page 7318]]
anticipate that allowing use of the TV white spaces by unlicensed
devices will have significant benefits for both businesses and
consumers and thereby promote more efficient and effective use of the
TV spectrum.
18. The Commission adopted a plan that will allow both fixed and
personal/portable unlicensed devices to operate on unused television
channels in locations where such operations will not result in harmful
interference to TV services (including reception by cable headends and
low power TV stations, i.e., TV translator, low power TV, TV booster,
and Class A TV stations) and other services that use the TV bands. The
Commission recognizes the importance of protecting licensed services
from harmful interference and the novel challenges involved in reliably
identifying unused TV channels. Therefore, it is taking a cautious and
conservative approach in this plan, balancing the need to provide
sufficient opportunities for proponents to develop viable unlicensed TV
band devices (TVBDs) with measures to ensure that such devices fully
protect the important licensed services that operate in the TV bands.
In allowing the introduction of unlicensed TVBDs, the Commission also
believes it is important to avoid the possibility of disrupting or
causing uncertainty in the DTV transition, the current ongoing process
whereby TV stations are changing from analog to digital (DTV)
operation. As set forth in the First Report and Order and Further NPRM
of Proposed Rulemaking (First R&O/Further NPRM) in this proceeding, the
Commission addressed this concern with regard to the DTV transition by
restricting the marketing of unlicensed TVBDs until February 18, 2009,
the date when the DTV transition will end and all full-power TV
stations will be operating on a single channel, and only with digital
signals.
19. The Commission anticipates that the capabilities of products
for operating in this spectrum will develop and evolve over time and
that much will be learned about the potential for unlicensed TVBDs to
cause interference to licensed services and how to avoid that
interference. Therefore, the Commission may need to revisit these rules
to make adjustments both to provide more flexibility for unlicensed
devices and to refine the protections for licensed services. Consistent
with our objective to allow unlicensed TVBDs to operate with the most
flexibility and capabilities possible consistent with protection of
licensed services, the Commission has directed its staff to conduct a
review and report to the Commission in two years from the date of this
Second Report and Order on the state of these devices, including the
types of devices on the market, the extent of their implementation,
technical developments, any interference problems that may have arisen,
and aspects of the rules that should be altered to increase features
and opportunities for use or to address conflicts.
20. The Commission also denied all aspects of a petition for
reconsideration submitted by the New America Foundation and the
Champaign Urbana Wireless Network (NAF/CUWN). In particular, the
Commission denied their request that it (1) Not re-open the issue of
whether to permit new uses of the TV bands on a licensed or unlicensed
basis; (2) allow personal/portable devices on channels 14-20; and (3)
allow marketing of new unlicensed TV band devices prior to the end of
the DTV transition.
21. Overview of Rules for Unlicensed TV Band Devices. The new rules
provide for operation of two types of unlicensed TVBDs that may provide
broadband data and other types of communications services: (1) Fixed
devices, which will operate from a fixed location with relatively
higher power and could be used to provide a variety of services
including wireless broadband access in urban and rural areas, and (2)
personal/portable devices, which will use lower power and could, for
example, take the form of devices such as Wi-Fi-like cards in laptop
computers or wireless in-home local area networks (LANs). In order to
operate without causing interference to licensed services, both types
of devices will be required to be able to reliably determine which
channels are occupied by licensed operations at their location at any
given time and to avoid interfering with services on those channels
using the following methods. Devices will be required to identify
unused channels as follows:
(a) A fixed device must employ both geo-location/database access
and spectrum sensing capabilities that enable the device to listen for
and identify the presence of signals from other transmitters; the geo-
location function for a fixed device may also be performed by a
professional installer;
(b) A personal/portable device must either (1) be under the control
of a fixed device or a personal/portable device that employs geo-
location/database access and spectrum sensing or (2) employ geo-
location/database access and spectrum sensing itself.
22. In addition, the Commission adopted rules that will allow for
certification of personal/portable devices that do not include geo-
location and database access capabilities and are not controlled by
another device but rather determine available channels using spectrum
sensing, perhaps in combination with some other techniques. These
devices will be required to meet a ``proof of performance'' standard
that they will not cause harmful interference to incumbent radio
services. Such devices will be subject to all of the other requirements
for personal/portable devices but would be limited to 50 milliwatts
(mW) EIRP rather than the 100 mW authorized for personal/portable
devices for which available channels are determined based on the geo-
location and database method. The certification process will require
submittal of a sample for testing in our laboratory and in the field
similar to the process that the FCC Laboratory followed for testing of
TV band devices. The sample device must be a fully functioning pre-
production prototype, identical to the device that will be marketed
except for cosmetics. The testing will be open to the public. The
application must also show how the device will protect the various
incumbent radio services discussed. The determination of whether to
certify the device will be based on a demonstrated ability to avoid
causing harmful interference with an extremely high degree of
reliability. If the device is certificated, the Commission will permit
routine certification of other devices that have identical
characteristics (i.e., have the identical electrical characteristics
and antenna system). It will endeavor to complete the certification
process within 180 days of submittal of the device for testing, barring
any unforeseen circumstances.
23. Fixed Devices. Fixed devices will be allowed to communicate
with other fixed devices and with personal portable devices. These
devices will be required to determine their geographic location through
an incorporated geo-location capability or from a professional
installer and to access and register with a database system that
contains records of protected services and receive back a list of the
available channels at their location. In addition, fixed devices will
be required to operate with antennas mounted outdoors and to use
spectrum sensing to identify any wireless microphone operations and any
other protected signals that might be present at their location but do
not appear in the database. These devices will be required to sense, at
levels as low as -114 dBm, TV signals (digital and analog), wireless
microphone signals, and signals of other services
[[Page 7319]]
that operate in the TV bands on intermittent basis. Fixed devices will
be allowed to operate at up to 1 watt (W) transmitter output power and
with a gain antenna to achieve 4 W equivalent isotropically radiated
power (EIRP), and to communicate with other fixed devices and personal/
portable devices, except that they may not communicate with personal/
portable devices when operating on channels in the range 2-20. The plan
for fixed devices is similar to the provisions of the draft standard
for TVBDs under consideration by IEEE 802.22.
24. Personal/portable Devices. Personal/portable devices will be
allowed to communicate with fixed devices and with other personal/
portable devices. These devices will be allowed to operate in two
different modes: (1) Mode I--client, whereby a personal/portable device
is controlled by a fixed or a personal/portable device operating in
Mode II that has determined the available channels in the area and/or
(2) Mode II--independent, whereby a personal/portable device determines
the available channels using its own internal geo-location/database
access capabilities. Personal/portable operations will be permitted at
up to 100 mW EIRP, with no antenna gain, except that when operating on
a channel adjacent to a TV station or other licensed station/service
and within the protected coverage area of that service, operations will
be limited to 40 milliwatts. A device operating in Mode II using its
own internal geo-location and database access capabilities will be
allowed to communicate with other personal/portable devices and
function as the master device in a master/client link with another
personal/portable device. Devices operating in either mode will be
required to sense TV signals, wireless microphone signals, and signals
of other services that operate in the TV bands, including those that
operate on an intermittent basis, at levels as low as -114 dBm.
Personal portable devices will not be required to register with the
database system.
25. All Devices. All unlicensed TV band fixed and personal/portable
TV band devices will be permitted to operate on TV channels 21-51,
excluding channel 37. In addition, fixed TVBDs that only communicate
with other fixed TVBDs will be permitted to operate on channels 2 and
5-20, except that they must avoid operation on channels used by private
land mobile radio service (PLMRS), i.e., public safety, and commercial
mobile radio service operations on channels in certain markets and
areas adjacent to them. Also, in individual markets where there are
Private Land Mobile Radio Service or Commercial Mobile Radio Service
(PLMRS/CMRS) operations on channels 14-20, two channels in the range
21-51 will be reserved for operation by wireless microphones such that
TVBDs will not be permitted on those channels. This plan for channel
use is consistent with the requests of the various white space
proponents and would reserve channels for a ``safe harbor'' for
operation of wireless microphones and ensure protection of the public
safety and other land mobile services that use channels 14-20. At this
time, we are only permitting fixed TVBDs to operate on channels that
are not immediately next to (first adjacent on either side of) the
channel of a TV station; personal portable devices will be allowed to
operate on first adjacent channels to a TV station subject to the power
limitation indicated. All unlicensed TV band devices will be required
to limit their out-of-band emissions in the first adjacent channel to a
level 55 dB below the power level in the channel they occupy, as
measured in a 100 kHz bandwidth. In addition, all TVBDs will be
required to comply with a more stringent out-of-band emissions band at
the edges of channels 36 and 38 that are adjacent to channel 37 in
order to protect medical telemetry devices on that channel 37. Fixed
devices will also be required to periodically transmit a signal with
their identification when they are operating. This will facilitate
identification of sources of interference. The database system for
fixed stations and personal/portable devices with geo-location and
database access capability will be managed by a database manager or
managers selected by our Office of Engineering and Technology. The
specific provisions of this plan are presented below.
TV Bands Database System Requirements
26. All unlicensed fixed TV band devices and all personal/portable
devices, except for those that operate in Mode I under control of a
fixed or Mode II personal/portable device, will be required to access a
TV bands database to obtain information on the available channels at
their location and all unlicensed fixed TVBDs will be required to
register their operations. In the NPRM and the First R&O/Further NPRM,
the Commission made proposals and asked for comment on a number of
specific provisions relating to this database system. In particular,
the Commission requested comment on the information about authorized
stations that should be in a database, such as geographic coordinates,
type and class of station, transmit power level, antenna height and
other antenna characteristics, the means by which an unlicensed device
would access the database, and how often the database would need to be
updated. The Commission addresses the specific plan for operation of
the database system, including the information to be stored in the
database, the requirements that apply to unlicensed TVBDs for accessing
the database system, the responsibilities of a database administrator,
and database administrator selection.
27. Database system plan and operation: The Commission has adopted
a database plan that will provide for efficient and effective
management of licensee and TVBD records and the identification of
available channels for TVBDs. As an initial matter, it will consider
authorizing more than one entity to operate a TV bands database. Thus,
depending on expressed interest to a solicitation for database
managers, the Commission could select multiple database administrators
that could offer services on a competitive basis. In this regard, the
Commission is mindful that sufficient safeguards must be put in place
to ensure that a TVBD would receive the same set of available channels
regardless of which database it queries such that entities compete
solely on the basis of cost and speed and efficiency of service. The
database(s) will be a privately owned and operated service that
unlicensed TV band devices must contact to obtain information on
channel availability at the locations where they are operated and, in
the case of fixed devices, to register their operation at those
locations. The Commission will permit database administrators to charge
fees for registration of fixed devices and the provision of lists of
available channels to fixed devices and personal/portable devices. It
believes that third parties will be in the best position to develop and
manage a database in a fair and equitable manner and to address the
day-to-day operational demands. Any TV bands database will be required
to contain information on: (1) All of the authorized services that
operate in the TV bands using fixed transmitters with designated
service areas, including full service and low power TV stations, (2)
the service paths of broadcast auxiliary point-to-point facilities, (3)
the geographic regions served by PLMRS/CMRS operations on channels 14-
20, (4) regions served by the Offshore Radiotelephone Service, and (5)
the locations of cable headends and low
[[Page 7320]]
power TV receive sites that are outside the protected contours of the
TV stations whose signals they receive. In addition, a TV bands
database will be required to contain the locations of registered sites
where wireless microphones and other low power auxiliary devices are
used on a regular or scheduled basis. A TV bands database will be
required to register unlicensed TV band devices in accordance with the
rules and to provide such devices with a list of the available channels
at the specific locations where they are operating.
28. Unlicensed TV band devices, except for those operating as a
client to a either a fixed device or a personal/portable device
operating in Mode II, will be required to contact a TV bands database
through the Internet to obtain a list of available channels at their
location in accordance with the rules set forth herein. Database
administrator(s) will define protocols so that TV band devices can
access a database automatically without human intervention. A TV bands
database will calculate the television channels that are available for
use by unlicensed TV band devices at their individual locations based
on the information in the database and consistent with the separation
distances set forth in the rules and then return a list of those
channels to the TV band device on an approximately real-time basis. A
device may then transmit only on those channels which the database
indicates are available for its use. The database system will also
record registration information from each fixed TV band device. The
registration information will include the device's location (geographic
coordinates) and contact information for its user/operator. This
registration information will assist TV band device users in
coordinating efficient use of the available television channels at a
particular location. In addition, should any interference to licensed
services occur, the registration information will assist in the
identification of the source of any such interference. Finally, a TV
bands database will include provisions for sharing registration data
with any other Commission authorized TV bands database.
29. In considering a minimum interval for re-contacting the
database system, it is important to note that protection is afforded
not only to TV and other fixed facilities that do not change often, but
also to mobile/portable facilities such as wireless microphones. As
already described, the Commission will allow venues where wireless
microphones and other low power auxiliary devices are used on a regular
or scheduled basis to register such usage in the TV bands database.
Because such usage could change on a daily basis, the Commission will
require that fixed and mode II TVBDs to recheck the database, at a
minimum, on a daily basis. Rechecking in this manner will also provide
for timely protection of new or modified licensed facilities. This
approach accounts for the continual changes that will occur over time
as new licenses are issued or inaccuracies are corrected. The
Commission believes that because database access will be performed
automatically over the Internet, rechecking the available channels will
not be burdensome. If a device fails to contact a TV bands database on
any given day, it will be required to cease transmitting after a one-
day grace period. That is, it must cease operating at 11:59 PM on the
day following a day when it does not contact a TV bands database. This
grace period will allow for situations where there has been a sustained
power loss, an Internet outage, or other circumstances that disrupt a
device's ability to contact a TV bands database. In accessing a TV
bands database to update its list of available channels, a device will
only need to provide its identification information, current location
and, for fixed devices, any changes in its registration information.
30. In addition to the daily database update requirement, personal/
portable devices operating in Mode II will be required to re-establish
their location coordinates and to access a TV bands database for a list
of available channels each time they are activated, i.e., powered on,
or move. If such a device maintains a powered on state for one day or
more, the device will then be required to re-check a TV bands database
as described above. The Commission finds that these measures will
ensure that both fixed and personal/portable devices properly maintain
a current list of available channels.
31. Database information. To ensure that a TV bands database
contains sufficient elements to both determine available TV channels
for a given location and to register fixed TVBDs, the Commission must
define the set of data elements for the database. The elements for the
various types of systems that will be in the database are described
herein. Additionally, the Commission notes that for all coordinates it
will require that they be referenced to the North American Datum of
1983 (NAD 83) and as described, it will require accuracy to within 50
meters.
32. The information collected from fixed unlicensed TV band devices
will include:
(1) FCC Identifier (FCC ID) of the device;
(2) Manufacturer's serial number of the device;
(3) Device's coordinates (latitude and longitude);
(4) Name of the individual or business that owns the device;
(5) Name of a contact person responsible for the device's
operation;
(6) Address of the contact person;
(7) E-mail address of the contact person;
(8) Phone number of the contact person.
33. The information collected from personal/portable unlicensed TV
band devices, which will not be registered and only access the database
for available channels, will include:
(1) FCC Identifier (FCC ID) of the device;
(2) Manufacturer's serial number of the device;
(3) Device's coordinates (latitude and longitude).
34. The FCC ID and serial number of the TV band device will
uniquely identify individual fixed unlicensed TV band devices. This
information will assist the Commission if compliance issues concerning
devices arise. A fixed TV band device will be required to update any
information that has changed when it makes its daily check with a TV
bands database to determine if the list of available channels at its
location has changed. If a fixed device does not check the database for
three months, its registration will be removed from the database.
35. A database administrator will not be responsible for resolving
claims of interference from TVBDs. If there is a claim of interference,
a database administrator, upon request from the Commission, must
provide TVBD identifying information. If a device is found to be
causing interference, the Commission may then require that the party
responsible for the unlicensed device take corrective actions or cease
operating the device until the interference is resolved. In addition,
if a representative of the Commission attempts and is unable to contact
the person responsible for a device that is determined to be causing
interference, the Commission may require the TV bands database to
return a message of ``no channels available'' to the device at its next
scheduled re-check. This will effectively shut down the device until
contact is made with the responsible party so that the interference can
be resolved. The database administrator
[[Page 7321]]
will rescind a ``no channels available'' status for that device only
upon authorization by the Commission.
36. Now, regarding services that will be protected, a TV bands
database will contain the following information on full-power
television stations, digital and analog Class A stations, low-power
television stations (LPTV), television translator stations, and
television booster stations:
(1) Transmitter coordinates (latitude and longitude);
(2) Effective radiated power (ERP);
(3) Height above average terrain of the transmitter (HAAT);
(4) Horizontal transmit antenna pattern (if the antenna is
directional);
(5) Channel number;
(6) Station call sign.
A TV bands database will also be required to include data on the
distributed transmission system (DTS) facilities of stations using that
technology and to use that data in determining the protected service
areas of such stations. The information for full service TV stations is
available on the Media Bureau's Consolidated Data Base System (CDBS).
37. A TV bands database will also include information on Broadcast
Auxiliary Service (BAS) facilities, which use vacant television
channels for fixed point-to-point links. For permanent links, this
information is available from the Commission's Universal Licensing
System (ULS). For temporary BAS links, the party authorized to operate
the link may voluntarily submit this information to a TV bands
database. For each BAS link the TV bands database will contain:
(1) Transmitter coordinates (latitude and longitude);
(2) Receiver coordinates (latitude and longitude);
(3) Channel number;
(4) Call sign.
38. In some geographic regions, certain television channels from
channel 14 through channel 20 are set aside for use by PLMRS and CMRS
operations. These regions are specified in the Commissions rules. A TV
bands database will contain the center coordinates (latitude and
longitude) for each of these regions and the television channels used
in each region. For each of these regions, a TV bands database will
include the following data elements:
(1) Region name;
(2) Channel(s) reserved for use in the region;
(3) Geographic center of the region (latitude and longitude);
(4) Call sign.
39. In addition, numerous PLMRS and CMRS licenses have been granted
in these channels outside of the identified geographic regions under
waivers to the Commission's rules. These ``waiver'' licenses are
specified in various ways such as, for example, by allowing a
particular transmitted power and antenna height for a base station at a
specified location or by specifying a geographic area of coverage, such
as the boundaries of a local county administrative area. The database
can be populated by information pertaining to facilities authorized by
the Commission via an extract from the Wireless Telecommunication
Bureau's ULS database. This database contains information on license
holders, facility operation parameters (frequency, location, etc.), and
any special conditions that apply. For each of these waiver licenses
the following information will be placed into a TV bands database:
(1) Transmitter location (latitude and longitude) or geographic
area of operations;
(2) Effective radiated power;
(3) Transmitter height above average terrain (if specified);
(4) Antenna height above ground level (if specified);
(5) Call sign.
In cases where the operator of a PLMRS/CMRS system licensed under a
waiver operates multiple transmitters (not including systems that are
licensed to operate in a coverage area), information on each
transmitter will be required to be maintained in a TV bands database.
40. The Offshore Radiotelephone Service uses channels 15-18 along
the coast of the Gulf of Mexico. The Commission's rules designate four
regions to protect this service. For each of the four regions a TV
bands database will contain the following information:
(1) Geographic boundaries of the region (latitude and longitude for
each point defining the boundary of the region;
(2) Channel(s) used by the service in that region.
41. As noted, cable television systems often use antennas at their
headends to receive broadcast television signals and then retransmit
those signals to subscriber households throughout the cable system. In
many cases, cable systems are able to receive broadcast TV signals at
locations outside a stations' protected service contour by using high
gain antennas mounted on top of buildings or tall towers. Records
identifying cable systems that receive TV stations outside of their
service areas are not currently maintained in the Commission's
databases. As indicated, the Commission is extending protection to the
reception of TV signals by such cable headends. Therefore, we are
allowing cable operators to register, with a TV bands database, their
headends that receive TV signals outside of a station's protected
contour and requiring that a TV bands database afford protection to
those facilities in accordance with the provisions indicated. A TV
bands database will collect the following information to register a
cable headend:
(1) Name and address of cable company;
(2) Location of the headend receiver (latitude and longitude);
(3) Channel number of each television channel received, subject to
the following condition: channels for which the cable headend is
located within the protected contour of that channel's transmitting
station are not eligible for registration in the database;
(4) Call sign of each television channel received and eligible for
registration;
(5) Location (latitude and longitude) of the transmitter of each
television channel received.
42. Television translator and low power stations, including Class A
TV stations, rebroadcast the signal of a full service station or
another low power station. Like many cable headends, TV translators/low
power stations often receive the signal of the station they retransmit
outside the retransmitted station's protected contour. The TV
translators and low power stations that currently receive the signal
they retransmit off-the-air at locations beyond the originating
station's protected service contour are not currently recorded in the
Commission's databases. To protect the reception of signals at the
receive sites of these stations, the Commission will allow the
licensees of such translators and low power stations to register their
receive sites with a TV bands database and require the database to
afford those sites protection in the same manner as similarly situated
cable headends. A TV bands database will collect the following
information to register a translator/low power receive site:
(1) Call sign of the TV translator or low power TV station;
(2) Location of the TV translator or low power station receive site
(latitude and longitude);
(3) Channel number of the retransmitted television station, subject
to the following condition: a channel for which the television
translator receive site is located within the protected contour of that
channel's transmitting
[[Page 7322]]
station is not eligible for registration in the database;
(4) Call sign of the retransmitted television station;
(5) Location (latitude and longitude) of the transmitter of the
retransmitted television station.
43. As discussed, low power auxiliary stations such as wireless
microphones and wireless assist video devices operate in the television
bands on a secondary basis under part 74 of the Commission's rules.
These devices are usually licensed to operate over a broad geographic
area and a wide range of television channels. The use of these devices
is sometimes sporadic and nomadic and registration of the locations of
such operations' locations in a TV bands database would not be
practical. However, in many cases wireless microphones and wireless
assist video devices are used regularly and predictably, such as at
major sporting events facilities, movie studio lots, and television
studios. For these situations, the low power auxiliary device users
will be allowed to register in a TV bands database, the location where
the devices are used to aid in avoiding interference from TV band
devices. In the case of large event facilities such as race tracks and
golf courses, the Commission will allow multiple registrations with
different geographic coordinates to enable protection of the entire
site. The Commission will require that requests for registration of low
power auxiliary devices that operate on a seasonal basis, only on
certain days within a week or only at specific times include such
information; TVBDs will be restricted from operation in the channels
used at registered sites only on days and at times when low power
auxiliary devices at the sites are in operation. Low power auxiliary
registrations will be valid for no longer than a year, after which they
may be renewed. The database will collect the following information on
registered sites that use low power auxiliary devices:
(1) Name of the individual or business that owns the low power
auxiliary device(s);
(2) The name of a contact person;
(3) An address for the contact person;
(4) An e-mail address for the contact person (optional);
(5) A phone number for the contact person (optional);
(6) Coordinates where the device(s) are used (latitude and
longitude);
(7) Channels used by the low power auxiliary devices operated at
the site;
(8) Specific months, days and times when the device(s) are used.
44. Database Administration. The Commission does not maintain a
database of all TV and other stations and operations in the TV bands
that could be accessed regularly in real-time by a large number of
TVBDs dispersed throughout the country. It will designate one or more
database administrators from the private sector to create and operate a
TV bands database or databases. The Commission recognizes the interests
of Google and other TVBD proponents in ensuring that database services
be made available on a fair and low cost (or no cost) basis and
believes that providing for authorization of more than one party to
operate a TV bands database will serve that purpose. The Commission
will issue a public notice requesting proposals from entities desiring
to administer a TV bands database. Any entity that ultimately
administrators such a database must make its services available to all
TV band device users on a non-discriminatory basis. In addition, to
ensure stability for these new devices, the Commission will require
each database administrator to provide services for a five-year term,
which, at the Commission's discretion, may be renewed. In the event
that there is only a single a database administrator and that entity
does not wish to continue at the end of its term, it will be required
to transfer its database along with the IP address(es) and URL(s) used
to access the database to another designated entity and would be
allowed to charge a reasonable price for conveyance of that resource.
45. If the Commission chooses multiple entities to administer TV
bands databases, it must ensure that each database contains consistent
information so that regardless of which database a TVBD queries, it
receives the same list of available channels in an area. Because a TVBD
will only be required to contact a single TV bands database, there is a
need for the TV bands databases to share accurate and timely
registration information so that each database has a timely view of the
radio environment and can make the best channel availability
determinations possible. Therefore, the Commission will require that
each TV bands database, at a minimum on a daily basis, provide to each
other TV bands database, all registration information it receives
during the previous day. This data sharing requirement extends only to
registrations of fixed devices and protected facilities that are not
otherwise captured in Commission databases, including wireless
microphone and wireless assist video device locations, cable headends,
and TV translator/low power receive sites. The databases can obtain
information on other services, such as full service TV, land mobile
licenses, etc. directly from Commission databases. The Commission
believes that this sharing requirement is extremely important to the
success of TVBDs as it decreases the burden on any one database and
also fosters cooperation between the various database administrators.
Although, the Commission is requiring the TV bands databases to share
information daily, it will leave the actual implementation details up
to the database administrators. Once the specific entities are
selected, they will need to agree on a specific protocol and data
format requirement so that manufacturers can build standard devices
that can work with any of the databases and each database can easily
transmit and receive data from each other database. In addition, the
database administrators may agree whether to share on a more frequent
timeframe than daily.
46. A TV bands database will obtain much of the information on
licensed use of the television bands for populating the database from
the existing Commission databases. The TV bands database will be
required to synchronize itself with the existing Commission databases
at least once a week so that the information in the TV bands database
remains current. Entities operating facilities that are entitled to
protection but that are not licensed by the Commission, e.g., cable
headends and TV translator/low power TV station receivers, will
register their facilities through a process established by the database
administrators. The Commission will allow the TV bands databases to
charge fees necessary to support the creation and operation of the
database. These fees may be imposed on the operators of the TV band
devices for access to the database and/or on the manufacturers of TV
band devices, but not generally on users of the television bands who
are not currently in the Commission's database and desire to be
included in the database. The Commission does not believe it is
appropriate to charge operators of licensed service for protection of
their operations from unlicensed devices. It believes that competition
among databases will serve to keep fees low and reasonable. However, if
parties believe that the fees charged by a TV bands database are
excessive, they may petition the Commission for relief.
47. The Commission recognizes that there is potential for
inaccurate
[[Page 7323]]
information to be entered into the database, for omissions to occur,
and for records to be present for licensed facilities that are no
longer operating. Such inaccuracies could be introduced in several
ways. For example, any errors that might inadvertently be present in a
Commission database could be transferred to a TV bands database. In
addition, the fact that we are permitting information on certain
services in the TV bands to be voluntarily provided introduces another
potential for error. Parties submitting such information could
inadvertently provide inaccurate coordinates, channel or other
information, and there is also the potential that a party could
knowingly provide false information on channel use at a location. The
database administrators will be expected to respond quickly to verify
and/or correct data in the event that a party brings claims of
inaccuracies in the database to its attention, including advising the
Commission of any errors that may appear in the Commission's records.
Further, the Commission reserves the right to request the removal of
voluntarily submitted information from a TV bands database in the event
that such information is determined to be inaccurate or not in
compliance with the rules.
