FEDERAL COMMUNICATIONS COMMISSION
47 CFR Part 27
[WT Docket No. 03-66; RM-10586, FCC 04-135]
Facilitating the Provision of Fixed and Mobile Broadband Access,
Educational and Other Advanced Services in the 2150-2162 and 2500-2690
MHz Bands
AGENCY: Federal Communications Commission.
ACTION: Final rule; correction.
-----------------------------------------------------------------------
SUMMARY: The Federal Communications Commission (FCC) is correcting a
final
[[Page 1190]]
rule that appeared in the Federal Register of December 10, 2004 (69 FR
72020). This document renamed the Instructional Television Fixed
Service (ITFS) as the Educational Broadband Service (EBS) and renaming
the Multichannel Multipoint Distribution Service (MMDS) and the
Multipoint Distribution Service (MDS) as the Broadband Radio Service
(BRS). The rules restructure the 2500-2690 MHz band, designate the
2495-2500 MHz band for use in connection with the 2500-2690 MHz band,
establish a plan to transition licenses to the restructured 2500-2690
MHz band, adopt licensing, service, and technical rules to govern
licensees in the EBS and BRS, permit spectrum leasing for BRS and EBS
licensees under the Commission's secondary markets leasing policies and
procedures, and permit unlicensed operation in the 2655-2690 MHz band.
DATES: Effective January 10, 2005.
FOR FURTHER INFORMATION CONTACT: Genevieve Ross or Nancy Zaczek at 202-
418-2487.
SUPPLEMENTARY INFORMATION: In FR 04-26830 appearing on page 72020 in
the Federal Register of Friday, December 10, 2004, the following
corrections are made:
PART 27--[CORRECTED]
Sec. 27.50 [Corrected]
0
1. On page 72033, in the third column, section 27.50 is amended by
adding paragraphs (h)(3) and (h)(4) as follows:
Sec. 27.50 Power limits.
* * * * *
(h) * * *
(3) For television transmission, the peak power of the accompanying
aural signal must not exceed 10 percent of the peak visual power of the
transmitter. The Commission may order a reduction in aural signal power
to diminish the potential for harmful interference.
(4) For main, booster and response stations utilizing digital
emissions with non-uniform power spectral density (e.g. unfiltered
QPSK), the power measured within any 100 kHz resolution bandwidth
within the 6 MHz channel occupied by the non-uniform emission cannot
exceed the power permitted within any 100 kHz resolution bandwidth
within the 6 MHz channel if it were occupied by an emission with
uniform power spectral density, i.e., if the maximum permissible power
of a station utilizing a perfectly uniform power spectral density
across a 6 MHz channel were 2000 watts EIRP, this would result in a
maximum permissible power flux density for the station of 2000/60 =
33.3 watts EIRP per 100 kHz bandwidth. If a non-uniform emission were
substituted at the station, station power would still be limited to a
maximum of 33.3 watts EIRP within any 100 kHz segment of the 6 MHz
channel, irrespective of the fact that this would result in a total 6
MHz channel power of less than 2000 watts EIRP.''
* * * * *
Sec. 27.53 [Corrected]
0
2. On page 72034, in the second column, section 27.53 is amended by
adding paragraphs (l)(6) and (l)(7) as follows:
Sec. 27.53 Emission limits.
* * * * *
(l) * * *
(6) Measurement procedure. 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 outside
and adjacent to the frequency block a resolution bandwidth of at 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. With respect
to television operations, measurements must be made of the separate
visual and aural operating powers at sufficiently frequent intervals to
ensure compliance with the rules.
(7) Alternative out of band emission limit. Licensees in this
service may establish an alternative out of band emission limit to be
used at specified band edge(s) in specified geographical areas, in lieu
of that set forth in this section, pursuant to a private contractual
arrangement of all affected licensees and applicants. In this event,
each party to such contract shall maintain a copy of the contract in
their station files and disclose it to prospective assignees or
transferees and, upon request, to the FCC.
* * * * *
Sec. 27.1221 [Corrected]
0
3. On page 72041, in the first column, section 27.1221 is amended by
adding paragraphs (c), (d), and (e) as follows:
Sec. 27.1221 Interference protection.
* * * * *
(c) Protection for a Receiving-Antenna not Exceeding the Height
Benchmark. A base station receive-antenna with an HAAT less than or
equal to the height benchmark relative to a neighbor's transmitting
base station will be protected if that station's HAAT exceeds its
height benchmark. That station is required to take such measures to
limit the undesired signal at the receiving base station to -109dBm or
less.
(d) No Protection from a Transmitting-Antenna not Exceeding the
Height Benchmark. A base station transmitting-antenna with an HAAT less
than or equal to the height benchmark relative to a neighbor's
receiving antenna is not required to protect that receiving station,
regardless of the HAAT of that station.
(e) No Protection for a Receiving-Antenna Exceeding the Height
Benchmark. A base station transmitting-antenna with an HAAT greater
than the height benchmark relative to a neighbor's receiving antenna is
not required to protect that receiving antenna if its HAAT is greater
than its height benchmark.
