Federal Register / Vol. 73, No. 89 / Wednesday, May 7, 2008 / Rules and Regulations
PART 25—SATELLITE
COMMUNICATIONS
1. The authority citation for part 25
continues to read:
I
Authority: 47 U.S.C. 701–744. Interprets or
applies Sections 4, 301, 302, 303, 307, 309
and 332 of the Communications Act, as
amended, 47 U.S.C. Sections 154, 301, 302,
303, 307, 309 and 332, unless otherwise
noted.
2. Revise paragraphs (a)(2)(iii) and
(b)(5)(ii) of § 25.149 to read as follows:
I
§ 25.149 Application requirements for
ancillary terrestrial components in the
mobile-satellite service networks operating
in the 1.5/1.6 GHz, 1.6/2.4 GHz and 2 GHz
mobile-satellite service.
(a) * * *
(2) * * *
(iii) In the 1610–1626.5 MHz/2483.5–
2500 MHz bands (Big LEO bands), ATC
operations are limited to the 1610–
1617.775 MHz, 1621.35–1626.5 MHz,
and 2483.5–2495 MHz bands and to the
specific frequencies authorized for use
by the MSS licensee that seeks ATC
authority.
*
*
*
*
*
(b) * * *
(5) * * *
(ii) In the Big LEO bands, MSS ATC
is limited to no more than 7.775 MHz
of spectrum in the L-band and 11.5 MHz
of spectrum in the S-band. Licensees in
these bands may implement ATC only
on those channels on which MSS is
authorized, consistent with the Big LEO
band-sharing arrangement.
*
*
*
*
*
I 3. Add paragraph (d) to § 25.254 to
read as follows:
§ 25.254 Special requirements for ancillary
terrestrial components operating in the
1610–1626.5 MHz/2483.5–2500 MHz bands.

(d) To avoid interference to an
adjacent channel licensee in the
Broadband Radio Service (BRS), the
power of any ATC base station emission
above 2495 MHz shall be attenuated
below the transmitter power (P)
measured in watts in accordance with
the standards below. If these measures
do not resolve a documented
interference complaint received from
the adjacent channel BRS licensee, the
provisions of § 25.255 shall apply.
(1) For base stations, the attenuation
shall be not less than 43 + 10 log (P) dB
at the upper edge of the authorized ATC
band, unless a documented interference
complaint is received from an adjacent
channel licensee in the BRS. Provided
that a documented interference
complaint cannot be mutually resolved
between the parties, the following

Jkt 214001
additional attenuation requirements set
forth in subsections (2)–(5) shall apply:
(2) If a pre-existing BRS base station
suffers harmful interference from
emissions caused by a new or modified
ATC base station located 1.5 km or more
away, within 24 hours of the receipt of
a documented interference complaint
the ATC licensee must attenuate its
emissions by at least 67 + 10 log (P) dB
measured at 3 megahertz above the edge
of the authorized ATC band, and shall
immediately notify the complaining
licensee upon implementation of the
additional attenuation.
(3) If a pre-existing BRS base station
suffers harmful interference from
emissions caused by a new or modified
ATC base station located less than 1.5
km away, within 24 hours of the receipt
of a documented interference complaint
the ATC licensee must attenuate its
emissions by at least 67 + 10 log (P) ¥20
log(Dkm/1.5) dB measured at 3
megahertz above the edge of the
authorized ATC band, or if both base
stations are co-located, limit its
undesired signal level at the pre-existing
BRS base station receiver(s) to no more
than ¥107 dBm measured in a 5.5
megahertz bandwidth and shall
immediately notify the complaining
licensee upon such reduction in the
undesired signal level.
(4) If a new or modified BRS base
station suffers harmful interference from
emissions caused by a pre-existing ATC
base station located 1.5 km or more
away, within 60 days of receipt of a
documented interference complaint the
licensee of the ATC base station must
attenuate its base station emissions by at
least 67 + 10 log (P) dB measured at 3
megahertz above the edge of the
authorized ATC band.
(5) If a new or modified BRS base
station suffers harmful interference from
emissions caused by a pre-existing ATC
base station located less than 1.5 km
away, within 60 days of receipt of a
documented interference complaint:
(i) the ATC licensee must attenuate its
base station emissions by at least 67 +
10 log (P) ¥20 log(Dkm/1.5) dB
measured 3 megahertz above the edge of
the authorized ATC band, or
(ii) if both base stations are co-located,
the ATC licensee must limit its
undesired signal level at the new or
modified BRS base station receiver(s) to
no more than ¥107 dBm measured in
a 5.5 megahertz bandwidth.
(6) Compliance with these rules is
based on the use of measurement
instrumentation employing a resolution
bandwidth of 1 MHz or greater.
However, in the 1 MHz bands
immediately above and adjacent to the
2495 MHz a resolution bandwidth of at
PO 00000
Frm 00088
Fmt 4700
Sfmt 4700
least one percent of the emission
bandwidth of the fundamental emission
of the transmitter may be employed. A
narrower resolution bandwidth is
permitted in all cases to improve
measurement accuracy, provided the
measured power is integrated over the
full required measurement bandwidth
(i.e., 1 MHz or 1 percent of emission
bandwidth, as specified). The emission
bandwidth is defined as the width of the
signal between two points, one below
the carrier center frequency and one
above the carrier center frequency,
outside of which all emissions are
attenuated at least 26 dB below the
transmitter power. When an emission
outside of the authorized bandwidth
causes harmful interference, the
Commission may, at its discretion,
require greater attenuation than
specified in this section.
