47 CFR Part 90

[WP Docket No. 07-100; FCC 07-85]


Editorial Amendments

AGENCY: Federal Communications Commission.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: In this document, the Federal Communications Commission 
(Commission) makes certain minor editorial amendments to its rules to 
correct errors or omissions of publication, eliminate duplicative 
language, or conform the rules with other rule sections in effort to 
provide clear and concise rules that are easy for the public to 
understand.

DATES: Effective July 27, 2007.

FOR FURTHER INFORMATION CONTACT: Rodney P. Conway, at 
Rodney.Conway@FCC.gov, Wireless Telecommunications Bureau, (202) 418-
2904, or TTY (202) 418-7233.

SUPPLEMENTARY INFORMATION: This is a summary of the Commission's Order 
in WP Docket No. 07-100, FCC 07-85, adopted on May 9, 2007, and 
released May 14, 2007. The full text of this document is available for 
inspection and copying during normal business hours in the FCC 
Reference Center, 445 12th Street, SW., Washington, DC 20554. The 
complete text may be purchased from the Commission's copy contractor, 
Best Copy and Printing, Inc., 445 12th Street, SW., Room CY-B402, 
Washington, DC 20554. The full text may also be downloaded at: https://
www.fcc.gov. Alternative formats are available to persons with 
disabilities by sending an e-mail to fcc504@fcc.gov or by calling the 
Consumer & Governmental Affairs Bureau at 202-418-0530 (voice), 202-
418-0432 (tty).
    1. Part 90 contains the rules for both the Private Land Mobile 
Radio (PLMR) Services and certain Commercial Mobile Radio Services 
(CMRS). PLMR licensees generally do not provide for-profit 
communications services. Some examples of PLMR licensees are public 
safety agencies, businesses that use radio only for their internal 
operations, utilities, transportation entities, and medical service 
providers. CMRS licensees, by comparison, do provide for-profit 
communications services, such as paging and Specialized Mobile Radio 
services that offer customers communications that are interconnected to 
the public switched network.
    2. We take this opportunity to make certain minor editorial 
amendments to part 90 to correct errors or omissions of publication, 
eliminate duplicative language, and conform language among rule 
sections.

I. Procedural Matters

A. Paperwork Reduction Act

    3. This document does not contain proposed information 
collection(s) subject to the Paperwork Reduction Act of 1995 (PRA), 
Public Law 104-13. In addition, therefore, it does not contain any new 
or modified ``information collection burden for small business concerns 
with fewer than 25 employees,'' pursuant to the Small Business 
Paperwork Relief Act of 2002, Public Law 107-198, see 44 U.S.C.

    (14) Operation on this frequency is limited to a maximum output 
power of 1 watt and each station authorized will be classified and 
licensed as a mobile station. Any units of such a station, however, may 
provide the operational functions of a base or fixed station on a 
secondary basis to mobile service operations, provided that the 
separation between the control point and the center of the radiating 
portion of the antenna of any units so used does not exceed 8m (25 
ft.).

Sec.  90.263  Substitution of frequencies below 25 MHz.

    Frequencies below 25 MHz when shown in the radio pool frequency 
listings under this part will be assigned to base or mobile stations 
only upon a satisfactory showing that, from a safety of life 
standpoint, frequencies above 25 MHz will not meet the operational 
requirements of the applicant. These frequencies are available for 
assignment in many areas; however, in individual cases such assignment 
may be impracticable due to conflicting frequency use authorized to 
stations in other services by this and other countries. In such cases, 
a substitute frequency, if found available, may be assigned from the 
following bands: 1705-1750 kHz, 2107-2170 kHz, 2194-2495 kHz, 2506-2850 
kHz, 3155-3400 kHz, or 4438-4650 kHz. Since such assignments are in 
certain instances subject to additional technical and operation 
limitations, it is necessary that each application also include precise 
information concerning transmitter output power, type and directional 
characteristics, if any, of the antenna, and the minimum necessary 
hours of operation. (This section is not applicable to the

28. Revise Sec.  90.307 to read as follows:


Sec.  90.307  Protection criteria.

    The tables and figures listed in Sec.  90.309 shall be used to 
determine the effective radiated power (ERP) and antenna height of the 
proposed land mobile base station and the ERP for the associated 
control station (control station antenna height shall not exceed 31 
meters (100 feet) above average terrain (AAT)).
    (a) Base stations operating on the frequencies available for land 
mobile use in any urbanized area and having an antenna height (AAT) 
less than 152 meters (500 feet) shall afford protection to co-channel 
and adjacent channel television stations in accordance with the values 
set out in tables A and E of Sec.  90.309, except for channel 15 in New 
York, NY, and Cleveland, OH, and channel 16 in Detroit, MI, where 
protection will be in accordance with the values set forth in tables B 
and E in 47 CFR 90.309.
    (b) For base stations having antenna heights between 152 and 914 
meters (500-3000 feet) above average terrain, the effective radiated 
power must be reduced below 1 kilowatt in accordance with the values 
shown in the power reduction graph in Figure A in Sec.  90.309, except 
for channel 15 in New York, NY, and Cleveland, OH, and channel 16 in 
Detroit, MI, where the effective radiated power must be reduced in 
accordance with Figure B in Sec.  90.309. For heights of more than 152 
meters (500 feet) above average terrain, the distance to the radio path 
horizon will be calculated assuming smooth earth. If the distance so 
determined equals or exceeds the distance to the Grade B contour of a 
co-channel TV station (Grade B contour defined in Sec.  73.683(a) of 
this chapter), an authorization will not be granted unless it can be 
shown that actual terrain considerations are such as to provide the 
desired protection at the Grade B contour, or that the effective 
radiated power will be further reduced so that, assuming free space 
attenuation, the desired protection at the Grade B contour will be 
achieved.
    (c) Mobile units and control stations operating on the frequencies 
available for land mobile use in any given urbanized area shall afford 
protection to co-channel and adjacent channel television stations in 
accordance with the values set forth in table C in Sec.  90.309 and 
paragraph (d) of this section except for channel 15 in New York, NY, 
and Cleveland, OH, and channel 16 in Detroit, MI, where protection will 
be in accordance with the values set forth in table D in Sec.  90.309 
and paragraph (d) of this section.
    (d) The minimum distance between a land mobile base station which 
has associated mobile units and a protected adjacent channel television 
station is 145 km (90 miles).
    (e) The television stations to be protected (co-channel, adjacent 
channel, IM, and IF) in any given urbanized area, in accordance with 
the provisions of paragraphs (a), (b), (c), and (d) of this section, 
are identified in the Commission's publication ``TV stations to be 
considered in the preparation of Applications for Land Mobile 
Facilities in the Band 470-512 MHz.'' The publication is available at 
the offices of the Federal Communications Commission in Washington, 
D.C. or upon the request of interested persons.

29. Amend Sec.  90.309 by revising paragraph (a)(4) and table B in 
paragraph (a)(5) to read as follows:


Sec.  90.309  Table and figures.

    (a) * * *
    (4) In determining the average elevation of the terrain, the 
elevations between 3.2 kilometers (2 miles) and 16 kilometers (10 
miles) from the antenna site are employed. Profile graphs shall be 
drawn for a minimum of eight radials beginning at the antenna site and 
extending 16 kilometers (10 miles). The radials should be drawn 
starting with true north. At least one radial should be constructed in 
the direction of the nearest co-channel and adjacent channel UHF 
television stations. The profile graph for each radial shall be plotted 
by contour intervals of from 12.2 meters (40 feet) to 30.5 meters (100 
feet) and, where the data permits, at least 50 points of elevation 
(generally uniformly spaced) should be used for each radial. For very 
rugged terrain, 61 meters (200 feet) to 122 meters (400 foot) contour 
intervals may be used. Where the terrain is uniform or gently sloping, 
the smallest contour interval indicated on the topographic chart may be 
used. The average elevation of the 12.8 kilometer (8 mile) distance 
between 3.2 kilometers (2 miles) and 16 kilometers (10 miles) from the 
antenna site should be determined from the profile graph for each 
radial. This may be obtained by averaging a large number of equally 
spaced points, by using a planimeter, or by obtaining the median 
elevation (that exceeded by 50 percent of the distance) in sectors and 
averaging those values. In the preparation of the profile graphs, the 
elevation or contour intervals may be taken from U.S. Geological Survey

[[Page 35198]]

Topographic Maps, U.S. Army Corps of Engineers Maps, or Tennessee 
Valley Authority Maps. Maps with a scale of 1:250,000 or larger (such 
as 1:24,000) shall be used. Digital Terrain Data Tapes, provided by the 
National Cartographic Institute, U.S. Geologic Survey, may be utilized 
in lieu of maps, but the number of data points must be equal to or 
exceed that specified above. If such maps are not published for the 
area in question, the next best topographic information should be used.

    (4) * * *
    (iii) In the Industrial/Business Pool, railroad licensees (as 
defined in Sec.  90.7) may identify stations by the name of the 
railroad and the train number, caboose number, engine number, or the 
name of the fixed wayside station. If none of these forms is 
practicable, any similar name or number may be designated by the 
railroad concerned for use by its employees in the identification of 
fixed points or mobile units, provided that a list of such identifiers 
is maintained by the railroad. An abbreviated name or the initials of 
the railroad may be used where such are in general usage. In those 
areas where it is shown that no difficulty would be encountered in 
identifying the transmission of a particular station (as, for example, 
where stations of one licensee are located in a yard isolated from 
other radio installations), approval may be given to a request from the 
licensee for permission to omit the station identification.
    (5) Use of identifiers in addition to assigned call signs. Nothing 
in this section shall be construed as prohibiting the transmission of 
station or unit identifiers which may be necessary or desirable for 
system operation, provided that they are transmitted in addition to the 
assigned station call sign or other permissible form of identification.

two letter manufacturer's designator, authorized by the Commission on 
the station authorization, at the beginning and ending of each 
transmission and once every 15 minutes during periods of continuing 
operation. The designator shall be transmitted in International Morse 
Code at a speed not exceeding 25 words per minute, and the spread 
spectrum mode of operation shall be maintained while the designator is 
being transmitted. The identifying signal shall be clearly receivable 
in the demodulated audio of a narrow-band FM receiver.

conjunction with other approved methods of transmitter control and 
interconnection so long as the internal transmitter control system, 
itself, is neither accessed from telephone positions in the public 
switched telephone network (PSTN), nor uses dial-up circuits in the 
PSTN. Licensees with complex communications systems involving fixed 
systems whose base stations are controlled by such systems may 
automatically access these base stations through the microwave or 
operational fixed systems from positions in the PSTN, so long as the 
base stations and mobile units meet the requirements of Sec.  90.483

    (ii) When a frequency is shared by more than one system, automatic 
monitoring equipment must be installed at the base station to prevent 
activation of the transmitter when signals of co-channel stations are 
present and activation would interfere with communications in progress. 
Licensees may operate without the monitoring equipment if they have 
obtained the consent of all co-channel licensees located within a 120 
kilometer (75 mile) radius of the interconnected base station 
transmitter. A statement must be submitted to the Commission indicating 
that all co-channel licensees have consented to operate without the 
monitoring equipment. If a licensee has agreed that the use of 
monitoring equipment is not necessary, but later decides that the 
monitoring equipment is necessary, the licensee may request that the 
co-channel licensees reconsider the use of monitoring equipment. If the 
licensee cannot reach an agreement with co-channel licensees, the 
licensee may request that the Commission consider the matter and assign 
it to another channel. If a new licensee is assigned to a frequency 
where all the co-channel licensees have agreed that the use of 
monitoring equipment is not necessary, and the new licensee does not 
agree, the new licensee may request the co-channel licensees to 
reconsider the use of monitoring equipment. If the new licensee cannot 
reach an agreement with co-channel licensees, it should request a new 
channel from the Commission. Systems on frequencies above 800 MHz are 
exempt from this requirement.
