found in Appendix C at <a href="https://docs.fcc.gov/public/attachments/FCC-23-26A1.pdf">https://docs.fcc.gov/public/attachments/FCC-23-26A1.pdf</a>. Written public comments are requested on the IRFA. These
comments must be filed in accordance with the same filing deadlines for
comments on the NPRM, and they should have a separate and distinct
heading designating them as responses to the IRFA. The Commission's
Consumer and Governmental Affairs Bureau, Reference Information Center,
will send a copy of the NPRM, including the IRFA, to the Chief Counsel
for Advocacy of the Small Business Administration, in accordance with
the RFA.
Ex Parte Rules--Permit but Disclose. Pursuant to Sec. 1.1200(a) of
the Commission's rules, this Notice of Proposed Rulemaking (NPRM) shall
be treated as a ''permit-but-disclose'' proceeding in accordance with
the Commission's ex parte rules. Persons making ex parte presentations
must file a copy of any written presentation or a memorandum
summarizing any oral presentation within two business days after the
presentation (unless a different deadline applicable to the Sunshine
period applies). Persons making oral ex parte presentations are
reminded that memoranda summarizing the presentation must (1) list all
persons attending or otherwise participating in the meeting at which
the ex parte presentation was made, and (2) summarize all data
presented and arguments made during the presentation. If the
presentation consisted in whole or in part of the presentation of data
or arguments already reflected in the presenter's written comments,
memoranda, or other filings in the proceeding, the presenter may
provide citations to such data or arguments in his or her prior
comments, memoranda, or other filings (specifying the relevant page
and/or paragraph numbers where such data or arguments can be found) in
lieu of summarizing them in the memorandum. Documents shown or given to
Commission staff during ex parte meetings are deemed to be written ex
parte presentations and must be filed consistent with rule 1.1206(b).
In proceedings governed by rule 1.49(f) or for which the Commission has
made available a method of electronic filing, written ex parte
presentations and memoranda summarizing oral ex parte presentations,
and all attachments thereto, must be filed through the electronic
comment filing system available for that proceeding, and must be filed
in their native format (e.g., .doc, .xml, .ppt, searchable .pdf).
Participants in this proceeding should familiarize themselves with the
Commission's ex parte rules.
Synopsis
In the Notice of Proposed Rulemaking (NPRM), the Commission
proposes to: (1) implement certain WRC-15 allocation decisions not
previously addressed; (2) make other allocation changes that are not
related to WRC-15 implementation; and (3) revise parts 2, 25, 74, 78,
90, 97, and 101 of the rules to reflect the proposed allocation
changes. Proposals that are not related to WRC-15 implementation are:
(1) restricting the use of the mobile-satellite service (Earth-to-
space) in the frequency bands designated for use by the Automatic
Identification System (AIS 1-4) to non-Federal space station reception
of AIS messages; (2) deleting the broadcasting service allocation from
the 700 MHz band; (3) updating the rules to recognize that the
transition period for the reallocation of the 18.3-19.3 GHz band from
the fixed service to the fixed-satellite service (space-to-Earth) has
concluded; and (4) removing eight inactive call signs from Sec.
2.106(d)(62) (footnote NG62 or NG62).
A. Satellite Issues
1. Protection of Search and Rescue Satellites Receiving in the 406-
406.1 MHz Band
The Commission proposes to adopt new Sec. 2.106(c)(265) (footnote
US265 or US265) for the 403-410 MHz band to protect satellite-based
search and rescue systems operating in the 406-406.1 MHz band from out-
of-band emissions originating from operations in adjacent bands, as
provided in Resolution 205 (Rev.WRC-19). The Commission's rules
authorize Emergency Position-Indicating Radio Beacon, Emergency Locator
Transmitter, and Personal Locator Beacon transmissions to Federal
Government satellites that carry Search and Rescue Satellite (SARSAT)
receivers. The National Oceanic and Atmospheric Administration (NOAA)
operates polar orbiting and geostationary satellites that carry
payloads providing distress alert and location information to
appropriate public safety rescue authorities for maritime, aviation,
and land users in distress. 47 CFR 80.209(a)(7), 80.905(a)(3)(vi),
(a)(4)(vi), 80.1077, 80.1129(c), 87.139(h), 87.147(e), 87.173(b),
87.187(m), 87.195(a), 87.199, 95.2963, and 95.2971. Proposed US265
would prohibit new frequency assignments within the 405.9-406.0 MHz and
406.1-406.2 MHz bands under the mobile and fixed services allocations.
Assignment (of a radio frequency or radio frequency channel) is defined
as an authorization given by an administration for a radio station to
use a radio frequency or radio frequency channel under specified
conditions. 47 CFR 2.1(c). In general, the assignment of
[[Page 67162]]
frequencies and frequency bands must be in accordance with the
Allocation Table. 47 CFR 2.102(a). The radio frequency devices
authorized pursuant to 47 CFR part 15 are not based on allocated radio
services. Note 1 to paragraph (e) of Sec. 2.105. The term ``short-
range radiocommunication devices'' is intended to cover radio
transmitters that have low capability of causing interference to other
radio equipment. In general, such devices are permitted to operate on a
non-interference, no-protection-from-interference basis. Simple
licensing requirements may be applied, e.g. general licenses or general
frequency assignments or even license exemption. See Recommendation
ITU-R SM.1538-1, Annex 1, p. 2 at 2 (Definition of short-range
radiocommunication devices). Medical Device Radio Communications
(MedRadio) devices, similar to part 15 devices, are short-range
devices.
For radiosonde applicants that seek to operate in the 403-410 MHz
band, proposed US265 would require that the frequency drift
characteristics of radiosondes be taken into account when selecting
operating frequencies above 405 MHz to avoid transmitting in the 406-
406.1 MHz band and that all practical steps be taken to avoid the
operating frequency drifting close to 406 MHz. The 403-406 MHz band is
a Federal/non-Federal shared band that is allocated to the
meteorological aids service (radiosonde) on a primary basis. The
Commission licenses radiosondes under its part 5 experimental radio
service; however, there are currently no active licenses for non-
Federal radiosonde use of the 403-406 MHz band. 47 CFR part 5. Proposed
US265 seeks to address concerns that aggregate levels of
electromagnetic interference, including interference from transmissions
in adjacent frequency bands, may present a risk of satellite emergency
transmissions being undetected, or delayed in reception, or lead to
reduced accuracy of the calculated locations. The Commission seeks
comment on this proposal.
Currently, non-Federal use of the fixed and mobile services in the
adjacent 403-406 MHz and 406.1-410 MHz bands is permitted pursuant to
47 CFR 2.106(c)(13), (55), (64) (footnotes US13, US55, and US64, or
US13, US55, and US64). Footnote US64 states, inter alia, that the 401-
406 MHz band is allocated to the mobile, except aeronautical mobile,
service on a secondary basis, and that non-Federal use is limited to
medical device radiocommunication service (MedRadio) operations.
MedRadio is an ultra-low power radio service that is associated with
medical implant devices and medical body-worn devices. MedRadio
stations are licensed-by-rule and operate in accordance with part 95,
subpart I of the rules, so the Commission does not issue individual
station licenses for MedRadio devices. Hence, the Commission
tentatively concluded that continued operations of MedRadio devices are
consistent with proposed US265. The Commission seeks comment on this
tentative conclusion.
Section 2.106(c)(13) (footnote US13 or US13) and Sec. 90.265 of
the Commission's rules make 48 channels available for transmitting
hydrological and meteorological data (Hydro channels), including
channels with center frequencies 406.125 MHz and 406.175 MHz. The
Commission proposes to revise Sec. Sec. 2.106 and 90.265 to state
that, after the effective date of final rules in this proceeding, no
assignments for the frequencies 406.1250 MHz and 406.1750 MHz will be
made, and that existing stations may continue to operate indefinitely
on these frequencies as they are currently licensed. As of April 18,
2023, 63 licenses in the Commission's Universal Licensing System
authorized operation in the 406.125-406.175 MHz band. This NPRM does
not modify those licenses. By no longer issuing licenses for the
frequencies 406.1250 MHz and 406.1750 MHz, the Commission would ensure
consistency with proposed new footnote US265 and protect satellite-
based search and rescue systems operating in the adjacent 406-406.1 MHz
band from out-of-band emissions originating on those frequencies. The
Commission seeks comment on these proposals.
Section 2.106(c)(55) (footnote US55 or US55) provides that the
Commission may authorize public safety use of 40 Federal
Interoperability Channels that are designated in section 4.3.16 of the
NTIA Manual. However, because section 4.3.16 of the NTIA Manual does
not include frequencies within the 406.1-406.2 MHz sub-band, it is not
necessary to amend the language of this footnote. Finally, the
Commission proposes to update Sec. 2.106(c)(117) (footnote US117 or
US117) to properly reflect that non-Federal use of the 406.1-410 MHz
band is limited to the radio astronomy service and as provided by
footnotes US13 and US55, as shown in the proposed rules. This proposed
revision of US117 was overlooked when the Commission originally adopted
US55. The Commission seeks comment on these proposals, including any
estimates of the costs and benefits of implementation.
2. Space Research Service (Space-to-Space) in the 410-420 MHz Band
The Commission proposes to allocate the 410-420 MHz band to the
space research service (space-to-space) on a secondary basis for non-
Federal use, and add Sec. 2.106(b)(268) (footnote 5.268) to the non-
Federal Table of Allocations in the 410-420 MHz band, which would limit
use of this added space research service allocation to communication
links with an orbiting, manned space vehicle and require compliance
with a power flux-density limit at the Earth's surface to protect
existing and future licensees. Footnote 5.268 limits the power flux-
density (PFD) at the surface of the Earth to maximum specified values
(-153 to -148 dBW/m\2\ in a 4 kilohertz bandwidth) depending on the
angle of arrival and prohibits stations in the space research service
from claiming protection from, or constraining the use and development
of, stations of the fixed and mobile services. 47 CFR 2.106(b)(268).
The 410-420 MHz band is currently allocated to the fixed, mobile, and
space research (space-to-space) services on a primary basis for Federal
use; the 413-419 MHz segment is allocated to the mobile, except
aeronautical mobile, service on a secondary basis, with non-Federal use
limited to part 95 MedRadio operations. 47 CFR 2.106(a). The National
Aeronautics and Space Administration (NASA) operates systems in support
of extra-vehicular activity communications for the manned space program
and other space related efforts in this band. The systems are used for
communications between crew members and for relaying telemetry data to
the main spacecraft. Non-Federal use is limited to MedRadio operations,
hydrological/meteorological data, and public safety. The Commission
expects that the additional non-Federal use would be similar to the
current Federal uses and would occur because of increasing space
exploration by private companies. The Commission requests comment on
these proposals, including information on the costs and benefits.
3. Global Flight Tracking for Civil Aviation (1087.7-1092.3 MHz)
The Commission proposes to allocate the 1087.7-1092.3 MHz band to
the aeronautical mobile-satellite (route) service (Earth-to-space) on a
primary basis, limited to space station reception of automatic
dependent surveillance-broadcast (ADS-B) emissions from aircraft. If
adopted, the Commission would implement this proposed allocation by
referencing Sec. 2.106(b)(328)(ii) (footnote 5.328AA) in
[[Page 67163]]
the 960-1164 MHz band within the U.S. Table. The 960-1164 MHz band is
currently allocated to the aeronautical mobile (route) and aeronautical
radionavigation services on a primary basis for Federal and non-Federal
use. Aircraft currently transmit ADS-B signals to report their position
to ground-based receivers in a 4.6-megahertz wide band centered on 1090
MHz under the existing aeronautical mobile (route) service allocation.
This proposed allocation would extend reception of ADS-B signals beyond
terrestrial line-of-sight to facilitate reporting the position of
aircraft located anywhere in the world. The Commission tentatively
concluded that providing for satellite reception of ADS-B signals would
ensure the efficient management of air traffic in oceanic, polar, and
remote airspace. Further, the Commission tentatively concluded that
this proposed allocation would support the Federal Aviation
Administration's rules regarding aircraft location information. The
Commission also proposes to add new paragraph (a)(13) to Sec. 25.202
of the Commission's rules to permit the licensing of space stations
that can receive ADS-B emissions from aircraft. The Commission seeks
comment on these proposals.
Further, as recommended by the National Telecommunications and
Information Administration (NTIA), the Commission proposes to add new
paragraph (78) to Sec. 2.106(c) (footnote US78 or US78) to the 960-
1164 MHz band to recognize Federal use by military Identification
Friend or Foe (IFF) systems on center frequencies 1030/1090 MHz. The
Commission proposes this use would be subject to the condition that
harmful interference would not be caused to the aeronautical
radionavigation service or the aeronautical mobile (R) service.
Finally, the Commission proposes to revise Sec. 2.106(c)(224)
(footnote US224 or US224) to require that Federal systems utilizing
spread spectrum techniques for terrestrial communication, navigation,
and identification in the 960-1215 MHz band be authorized on the
condition that harmful interference not be caused to the aeronautical
mobile (R) and aeronautical radionavigation services in the 960-1164
MHz band, military IFF systems on center frequencies 1030/1090 MHz,
aeronautical mobile-satellite (R) service (Earth-to-space) in the
1087.7-1092.3 MHz band, and the aeronautical radionavigation and
radionavigation-satellite (space-to-Earth) (space-to-space) services in
the 1164-1215 MHz band. The Commission requests comment on these
proposals, including whether any modifications to the part 87 rules for
aviation services would be necessary to implement these proposals.
4. Satellite Uplinks in the 7190-7250 MHz Band
As recommended by NTIA, the Commission seeks comment on whether to
provide additional spectrum on a secondary basis for non-Federal Earth-
to-space operations in the Earth exploration-satellite service in the
7190-7250 MHz band and space research service in the 7190-7235 MHz
band. In the U.S. Table, the 7190-7250 MHz band is allocated to the
Earth exploration-satellite (Earth-to-space) and fixed services, both
on a primary basis and exclusively for Federal use. The 7190-7235 MHz
portion of the band is also allocated on a primary basis to the space
research service (Earth-to-space) exclusively for Federal use.
Consistent with NTIA's recommendation, should the Commission make
these Federal uplink bands available for non-Federal use on a secondary
basis for Earth-to-space operations in the Earth exploration-satellite
and space research services, respectively, by adding the provisions of
proposed Sec. Sec. 2.106(c)(460) and (460)(i) (footnote US460 or
US460; footnote US460A or US460A) to the 7190-7235 MHz band and
footnote US460A to the 7235-7250 MHz band? Footnote US460 would provide
a secondary non-Federal allocation in the 7190-7235 MHz band for the
space research service (Earth-to-space) and would prohibit emissions
from such systems intended for deep space. Footnote US460A would
allocate the 7190-7250 MHz band to the Earth exploration-satellite
service (Earth-to-space) on a secondary basis for non-Federal use,
limited to tracking, telemetry, and command (TT&C) for the operation of
spacecraft. The restrictions in footnotes US460 and US460A are based on
international Sec. Sec. 2.106(b)(460), (460)(i) (footnotes 5.460 and
5.460A, or 5.460 and 5.460A). In both cases, should the Commission
explicitly require that authorizations be subject to a case-by-case
electromagnetic compatibility (EMC) analysis and approval? Qualcomm
urged the Commission to seek comment on whether such allocations would
``remain in line with the Commission's present spectrum priorities,''
noting that the Chairwoman has identified the 7-15 GHz spectrum range,
and some stakeholders, other administrations, and regional
organizations are considering the 7190-7250 MHz band for the next
generation wireless technology. The Commission requests comment on
these recommendations.
5. Earth Exploration-Satellite Service (Active) in the 9.2-9.3 GHz and
9.9-10.4 GHz Bands
The Commission seeks comment on allocating the 9.2-9.3 GHz and 9.9-
10.4 GHz bands to the Earth exploration-satellite service (active) on a
primary basis for Federal use and on a secondary basis for non-Federal
use, subject to Sec. Sec. 2.106(b)(474)(i), (b)(474)(ii),
(b)(474)(iii), and proposes Sec. 2.106(c)(474) (footnotes 5.474A,
5.474B, 5.474C, and US474D, or 5.474A, 5.474B, 5.474C, and US474D,
respectively). Footnote US474D is based on the text in Sec.
2.106(b)(474)(iv) (international footnote 5.474D or 5.474D), except
that the radiolocation service is not included in the 9.2-9.3 GHz band
because this allocation has secondary status in both the Federal and
non-Federal Tables, and the radionavigation service is not included in
the 9.9-10 GHz band because that allocation only applies in the
countries listed in Sec. 2.106(b)(478) (footnote 5.478 or 5.478). This
would implement WRC-15's expansion of the current worldwide Earth
exploration-satellite service (active) allocation in the 9.3-9.9 GHz
band by allocating 600 megahertz of additional spectrum in the adjacent
bands to this service, which would support the growing demand for
greater radar image resolution to satisfy global environmental
monitoring requirements. Spaceborne radars operating in this band
support a large number of scientific and geoinformation applications,
such as disaster relief and humanitarian aid, land use, and large area
coastal surveillance. The Commission requests comment on these
potential allocations.
In the U.S. Table, the 9.2-9.3 GHz band is allocated to the
maritime radionavigation service on a primary basis and to the
radiolocation service on a secondary basis for Federal and non-Federal
use, subject to Sec. Sec. 2.106(b)(472), (b)(474), (c)(110), and
(e)(59) (footnotes 5.472, 5.474, US110, and G59, or 5.472, 5.474,
US110, and G59, respectively. The 9.9-10.5 GHz band is allocated to the
radiolocation service on a primary basis for Federal use and on a
secondary basis for non-Federal use. The 9.975-10.025 GHz band is also
allocated to the meteorological-satellite service on a secondary basis
for use by weather radars. 47 CFR 2.106(b)(479). The 10-10.5 GHz and
10.45-10.5 GHz bands are allocated to the amateur and amateur-satellite
services on a secondary basis, respectively. Five footnotes apply to
the 10-10.5 GHz band: 47 CFR
[[Page 67164]]
2.106(b)(479), (c)(108), (c)(128), (d)(50), and (e)(32) (footnotes
5.479, US108, US128, NG50, and G32, or 5.479, US108, US128, NG50, and
G32, respectively). The 2023 World Radiocommunication Conference will
consider whether to identify the 10-10.5 GHz for International Mobile
Telecommunications (IMT) in ITU Region 2.
The four footnotes on which the Commission seeks comment on adding
to the 9.2-9.3 GHz and 9.9-10.4 GHz bands would limit their use to
systems in the Earth exploration-satellite service (active) requiring a
necessary bandwidth greater than 600 megahertz that cannot be fully
accommodated within the 9.3-9.9 GHz band (5.474A (Sec.
2.106(b)(474)(i))); protect the radio astronomy service in the 10.6-
10.7 GHz band from unwanted emissions (5.474B (Sec.
2.106(b)(474)(ii))); protect the space research service (space-to-
Earth) in the 8.4-8.5 GHz band from unwanted emissions (5.474C (Sec.
2.106(b)(474)(iii))); and require that the Earth exploration-satellite
service (active) not cause harmful interference to, or claim protection
from, the maritime radionavigation service in the 9.2-9.3 GHz band and
the radiolocation service in the 9.9-10.4 GHz band (proposed US474D
(Sec. 2.106(c)(474)). Qualcomm urged the Commission to seek comment on
whether the proposed allocations would ``remain in line with the
Commission's present spectrum priorities,'' noting that the Chairwoman
has identified the 7-15 GHz spectrum range, and some stakeholders,
other administrations, and regional organizations are considering the
9.2-9.3 GHz and 9.9-10.4 GHz bands for the next generation wireless
technology.
The Commission also proposes to revise Sec. 2.106(c)(128)
(footnote US128 or US128) to support the Department of Defense's
development of pulsed emission systems in the 10-10.5 GHz band.
Currently, US128 prohibits pulsed emissions in the 10-10.5 GHz band,
except for weather radars on board meteorological satellites in the 10-
10.025 GHz sub-band. Under footnote US128, the amateur, the amateur-
satellite, and the non-Federal radiolocation services, which shall not
cause harmful interference to the Federal radiolocation service, are
the only non-Federal services permitted in the 10-10.5 GHz band, and
the non-Federal radiolocation service is limited to survey operations
as specified in Sec. 2.106(c)(108) (footnote US108 or US108). NTIA
states that the Department of Defense requires flexibility for
development of pulsed systems in this band to meet future system needs.
The Commission seeks comment on all of the proposals in this section.
In addition, it requests comment on whether the 9.2-9.8 GHz and 9.9-
10.4 GHz bands should be allocated to the Earth exploration-satellite
service (active) on a primary basis for non-Federal use, so the status
of those non-Federal allocations would mirror the status of the Federal
Earth exploration-satellite service (active) allocations in those
bands.
6. Revision of the 18.142-19.3 GHz, 28.5-29.1 GHz, and 29.25-29.5 GHz
Bands
In this section, the Commission makes proposals and seeks comments
on allocation and service rule changes that would clarify the status of
grandfathered fixed stations in the 18.3-19.3 GHz band and permit a
heavier use of the fixed-satellite service (FSS) in the 18.142-18.3
GHz, 28.5-29.1 GHz, and 29.25-29.5 GHz bands.
First, the Commission proposes to amend Sec. 2.106(c)(139)
(footnote US139 or US139) by stating that, in the 18.3-19.3 GHz band,
earth station licensees in the fixed-satellite service (space-to-Earth)
may require that licensees of grandfathered stations in the fixed
service cease operations, consistent with the provisions in Sec.
101.95 of the Commission's rules. The Commission makes this proposal
because, in the 18.3-19.3 GHz band, there is no fixed service
allocation and there are no longer any primary grandfathered fixed
stations. Specifically, Sec. 101.85 states that fixed service
operations in the 18.3-18.58 GHz and 18.58-19.3 GHz bands that remain
co-primary under the provisions of Sec. Sec. 74.502(c), 74.602(g),
78.18(a)(4), and 101.147(r) will continue to be co-primary with the
fixed-satellite service (FSS) until dates that have long since passed,
i.e., these transition periods have concluded. In addition, Sec.
101.95(a), which concerns the sunset provisions for the 18.3-19.3 GHz
band, includes the following: Once the relocation rules sunset, an FSS
licensee may require the incumbent to cease operations, provided that
the FSS licensee intends to turn on a system within interference range
of the incumbent, as determined by TIA Bulletin 10-F or any standard
successor. FSS licensee notification to the affected FS (fixed service)
licensee must be in writing and must provide the incumbent with no less
than six months to vacate the spectrum. After the six-month notice
period has expired, the FS licensee must turn its license back into the
Commission, unless the parties have entered into an agreement that
allows the FS licensee to continue to operate on a mutually agreed upon
basis. 47 CFR 101.85(b)(1) and (2), 101.95(a). Consequently, the
Commission also proposes to revise Sec. Sec. 74.502(c), 74.602(g),
78.18(a)(4), and 101.147(r) of the rules in order to update the
introductory text and the frequencies that are available to applicants
of aural broadcast auxiliary stations, television broadcast auxiliary
stations, cable television relay service, and fixed microwave services,
respectively. These proposals are consistent with the Commission's
previous decision concerning the re-channelization of the 17.7-18.3 GHz
and 19.3-19.7 GHz bands for fixed microwave services under part 101 of
the rules. While most of the proposed changes remove channels that are
no longer allocated to the fixed service, in one instance the
Commission proposes to add replacement channels, i.e., the Commission
proposes to replace the 12 frequency pairs in Sec. 74.502(c)(1)(i) of
the rules with the 5 megahertz channels from Sec. 101.147(r)(5) in the
proposed rules. The Commission also proposes to update Sec. Sec.
101.95(a) and 101.147(a) to remove expired text and to remove six
sections concerning expired policies governing fixed service relocation
from the 18.3-19.3 GHz band, i.e., Sec. Sec. 101.83 through 101.91 and
101.97. The Commission requests comment on these proposals.
Second, the Commission proposes to revise Sec. 2.106(d)(62)
(footnote NG62 or NG62) to permit the fixed stations authorized
pursuant to the 10 listed call signs to continue to operate
indefinitely on a secondary basis. The Commission adopted footnote NG62
when it deleted the primary fixed and mobile service allocations from
the 28.5-29.1 GHz and 29.25-29.5 GHz bands. Footnote NG62 states that,
in the 28.5-29.1 GHz and 29.25-29.5 GHz bands, stations in the fixed-
satellite service shall not cause harmful interference to, or claim
protection from, stations in the fixed service operating under 18
listed call signs; however, only 10 of these call signs are currently
active. The Commission noted that WRC-19 and the Commission's rules
permit earth stations in motion (ESIMs) to operate in these frequency
bands. The proposed secondary status of these fixed stations would
recognize that ESIMs, which may operate anywhere without coordination
with the fixed stations, may cause intermittent interference to these
fixed stations. The Commission requests comment on these proposals.
Third, the Commission requests comment on whether it should raise
the non-Federal secondary fixed-satellite service (space-to-Earth)
allocation in the
[[Page 67165]]
18.142-18.3 GHz band (158 megahertz) to primary status, i.e., co-equal
with the non-Federal primary fixed service allocation in the band. If
adopted, this upgrade of allocation status would provide receiving
earth stations with interference protection from later-licensed fixed
stations that are used for part 74 and part 101 Multichannel Video
Programming Distributor (MVPD) and part 78 cable television relay
service (CARS) operations that operate in accordance with the proposed
rules in this section. The Commission tentatively concluded this should
result in significantly heavier earth station use of this band in the
future, thereby enhancing spectrum efficiency. As background, the
Commission noted that there are seven part 78 CARS licenses, which are
located in three California counties and Maui Island, Hawaii; and 35
grandfathered fixed service licenses that authorize operations in the
18.142-18.3 GHz band. In contrast, as of August 26, 2022, there are 222
licenses for earth station reception in the 18.142-18.3 GHz band and
there are 414 pending applications for earth stations that would
receive in the band.
Finally, the Commission requests comment on whether it should allow
the continued operation of existing CARS licenses that authorize
operation in the 18.3-18.304 GHz and 18.3-18.334 GHz bands in Puu
Nianiau, Hawaii, and Placerville, California, respectively, and revise
Sec. 2.106(c)(139) (footnote US139 or US139) to codify that these
fixed station operations may continue to operate indefinitely under the
existing conditions.
7. Deletion of the Radionavigation-Satellite Service From the 149.9-
150.05 MHz and 399.9-400.05 MHz Bands
Consistent with the WRC-15 Final Acts, the Commission proposes to
delete the radionavigation-satellite service allocation from the 149.9-
150.05 MHz and 399.9-400.05 MHz bands. WRC-15 deleted this allocation
because it had expired pursuant to footnote 5.224B. In the U.S. Table,
the 149.9-150.05 MHz and 399.9-400.05 MHz bands are Federal/non-Federal
shared bands that are allocated to the mobile-satellite service (Earth-
to-space) and the radionavigation-satellite service on a primary basis.
This proposal would make these two bands--totaling 300 kilohertz--
exclusively allocated to the mobile-satellite service (Earth-to-space).
The Commission seeks comment on this proposal.
B. Terrestrial Issues
1. Amateur Service in the 5351.5-5366.5 kHz Band
The Commission proposes to allocate the 5351.5-5366.5 kHz band to
the Amateur Radio Service on a secondary basis and seeks comment on
whether the amateur service should keep the existing channels they use
in the 60 meter band. During WRC-15, the International
Telecommunication Union (ITU) allocated this band to the amateur
service on a secondary basis in all ITU Regions. The ITU generally set
the maximum radiated power at 15 watts (W) equivalent isotropically
radiated power (EIRP), which is equivalent to 9.15 W effective radiated
power (ERP).
These frequencies are currently part of the 5275-5450 kHz band,
which is allocated for Federal/non-Federal shared use, on a primary
basis, to the fixed service and, on a secondary basis, to the mobile
except aeronautical mobile service. Section 2.106(c)(23) (footnote US23
or US23) currently provides a secondary allocation to the amateur
service on five discrete channels--each with a maximum bandwidth of 2.8
kilohertz and centered on the frequencies 5332, 5348, 5358.5, 5373, and
5405 kHz. While footnote US23 does not have an explicit bandwidth
limit, it limits use of these frequencies to specified emission types
and designators, which in effect limit the bandwidth to a maximum of
2.8 kilohertz, i.e. phone (2K80J3E), data (2K80J2D), RTTY [narrow-band
direct-printing telegraphy emissions having specified designators]
(60H0J2B), and CW [International Morse code telegraphy emissions having
specified designators] (150HA1A). 47 CFR 2.101, 2.102, 2.106(c)(23),
97.3(c)(1), (c)(7). However, pursuant to Commission rules, stations in
the amateur service may transmit on these frequencies with a maximum
radiated power of 100 W ERP--over ten times more powerful than WRC-15's
EIRP limit. Footnote US23 and Sec. 97.313(i) of the Commission's rules
state that amateur service use of these frequencies is restricted to a
maximum ERP of 100 watts ``PEP'' and that no station may transmit with
an ERP exceeding 100 watts ``PEP,'' respectively. These requirements
are inconsistent with the definitions in part 97 of the Commission's
rules, i.e., PEP is the average power supplied to the antenna
transmission line by a transmitter during one RF cycle at the crest of
the modulation envelope taken under normal operating conditions and ERP
is the product of the power supplied to the antenna and its gain
relative to a half-wave dipole in a given direction. 47 CFR 97.3(b)(2),
(3), (9). The Commission's review found that these rules were intended
to limit the radiated power to 100 watts ERP based on the 2006
agreement between NTIA and the American Radio Relay League, the
National Association for Amateur Radio (ARRL) and, to minimize
confusion, the Commission refers to this limit in its discussion.
Petition for Rule Making of ARRL, RM-11353, at Exhibit A (filed Oct.
10, 2006); 47 CFR 97.313(k), (l). NTIA recommended that the Commission
conform footnote US23 to the WRC-15 Final Acts by allocating the
5351.5-5366.5 kHz band to the amateur service on a secondary basis,
removing the four existing amateur channels outside this proposed new
amateur band, and restricting the maximum radiated power of amateur
operations in the band to 15 W EIRP. Federal agencies use the larger
5275-5450 kHz band for services that include military, law enforcement,
disaster relief, emergency, and contingency operations. Most non-
Federal operations in the 60 meter band are part 90 industrial business
pool land mobile operations.
In 2017, ARRL filed a petition for rulemaking asking the Commission
to allocate the 5351.5-5366.5 kHz band to the amateur service on a
secondary basis, as provided in the WRC-15 Final Acts, and also to
retain the four amateur service channels that are outside this band
(i.e., the frequencies 5332 kHz, 5348 kHz, 5373 kHz, and 5405 kHz).
Further, ARRL supports using the same operating rules in terms of
permitted emission types, power level, and access by class of amateur
licensee for the new contiguous allocation that is currently applied to
the existing five amateur channels. Essentially, ARRL supports
extending the provisions of footnote US23 and Sec. 97.303(h) of the
Commission's rules that apply to the existing five amateur channels,
including the 100 watt ERP limit, to the new allocation. Therefore,
ARRL disagrees with applying the 15 W EIRP limit suggested in the WRC-
15 Final Acts. While most commenters supported implementation of the
ARRL Petition as filed, some commenters disagreed with various aspects
of the ARRL Petition as addressed below. Some even argue that the
entire 60 meter band should be opened for amateur use at higher power
because they are not aware of any complaints of harmful interference.
Finally, the Commission noted that Canada has essentially implemented
the same rules as ARRL has requested.
The Commission proposes to modify footnote US23 and part 97 of its
rules
[[Page 67166]]
to implement the new international allocation at 5351.5-5366.5 kHz, but
also seeks comment on whether it should maintain the existing four
channels at 5332, 5348, 5373, and 5405 kHz that are outside of the new
allocation. Specifically, the Commission proposes to make the following
amendments to part 97 of the rules: (1) replace the five center
frequencies with the 5351.5-5366.5 kHz band in Sec. 97.301(b) through
(d) and 97.305(c); (2) simplify the frequency sharing requirements in
Sec. 97.303(h) by stating that amateur stations transmitting in the
band must not cause harmful interference to, and must accept
interference from, stations authorized by the United States and other
nations in the fixed service; and other nations in the mobile except
aeronautical mobile service; and (3) revise the emission standard in
Sec. 97.307(f)(14) by removing unneeded text, including the unneeded
upper sideband and Morse telegraphy restrictions (as requested by ARRL
in its petition).
Under this proposal, amateurs would have access to a contiguous 15
kilohertz-wide band. Allowing amateurs to use these internationally-
harmonized frequencies could facilitate amateur communications across
international borders. The Commission noted however, there is
significant opposition from the amateur community regarding the removal
of the four discrete channels at 5332, 5348, 5373, and 5405 kHz from
amateur use, as requested by NTIA. An argument could be made that
amateur operations should remain on harmonized international
frequencies because of the long-range propagation of these frequencies.
Further, amateur licensees also have access to other high frequency
(HF) bands at 3 and 7 MHz, so the Commission believed there should be
sufficient spectrum options for amateur operations without deviating
from the internationally harmonized spectrum. However, some commenters
contended that the amateur community has been using the four discrete
channels at 5332, 5348, 5373, and 5405 kHz that fall outside of the
proposed band for some time and argue that these channels are important
in responding to disasters. The Commission seeks comment on this issue
and what spectrum in the 60 meter band should be made available for
amateur use.
Alternatively, the Commission seeks comment on whether the four
discrete channels at 5332, 5348, 5373, and 5405 kHz should be kept
available for limited amateur use under certain conditions or only in
response to disasters. For example, could the channels be authorized
for amateur use during disasters as part of the Military Auxiliary
Radio System (MARS) or SHAred RESources High Frequency Radio (SHARES)
programs where participating amateur licensees can operate on Federal
channels in coordination with the Department of Defense or Department
of Homeland Security, respectively? Should the Commission permit
amateur stations participating in established emergency communications
programs such as the Amateur Radio Emergency Service (ARES) or the
Radio Amateur Civil Emergency Service (RACES) to use the additional
channels or operate at higher power during emergencies and drills?
Could the discrete channels be maintained under lower power or under
other conditions that might reduce their potential to interfere with
primary allocation services in the band? If so, the Commission invites
comment on whether the existing discrete channels should continue to be
used for secondary amateur use and under what rules and conditions.
While many amateur commenters argued they should be permitted
access to more of the 60 meter band because they are not aware of any
complaints of interference arising from their current operations, the
Commission noted there are a variety of important non-Federal and
Federal fixed and mobile except aeronautical mobile service operations
in the band where even rare instances of interference could endanger
public safety. Therefore, the Commission tentatively finds that the
spectrum requirements for the amateur service in the 5005-5450 kHz band
should be met by the WRC-15 amateur band and that only the four
existing amateur channels at 5332, 5348, 5373, and 5405 kHz that are
outside this band should be considered in this proceeding.
Nevertheless, the Commission seeks comment on this idea. Commenters
that support expanded access to the 60 meter band should provide
information regarding how heavily the five amateur frequencies in the
5275-5450 kHz band are used and why additional amateur spectrum in this
frequency range is needed if the Commission adopts the proposed
allocation.
Power. ARRL sought a maximum radiated power limit of 100 W ERP for
the new secondary amateur allocation and to maintain the existing
maximum radiated power limit of 100 W ERP for the existing discrete
channels at 5332, 5348, 5373, and 5405 kHz. ARRL argued that such an
implementation would support amateurs engaged in emergency and disaster
relief communications to more reliably, flexibly, and capably conduct
those communications; that imposing a maximum radiated power limit of
15 W EIRP would render the band unsuitable for emergency and public
service communications; that the lower power limit is insufficient to
permit reliable communications on the paths that are most critical; and
that this reduced radiated power limit is not necessary to protect
primary services from interference.
Harold Ross Lambert and Michael Goltz argued that the power limit
should be increased to 500 W to deal with propagation challenges in
disaster communications; and Milton K. Miller supports 500 W power with
the use of more efficient antennas. Phillip Finkle urged for at least
200 W of power designated as output power instead of ERP because ERP is
difficult to measure. Janis Carson initially expressed concern over
allowing U.S. amateurs to operate at much higher powers than the
international standard, suggesting a compromise power of 30 W because
digital modes are very effective at lower power and world-wide
communications can be achieved at lower power levels like 5 W. However,
in later comments Ms. Carson supported the ARRL proposal to allow 100 W
for ``more reliable communications in an environment of high static
crashes.'' William Springer urged the adoption of the 15 W power limit
in the WRC-15 Final Acts because he contends that newer digital modes
are more efficient, and so weaker signals are not an impediment to
achieving communication. Finally Hugh Bahar cautioned that deviating
from limits agreed to at the international level is unwise and could
lead to other countries ignoring the standards and could be viewed as
an act of bad faith.
Several commenters also argued for more flexibility in the types of
antennas permitted in the 60 meter band. Scott Wright and George
Dominick contend that antennas with gain greater than 0 dBi should be
allowed since they are essential for efficient communications during an
emergency. In contrast, Mathew Pitts does not support increasing the
permitted antenna gain and contends the power should range between 15
and 30 W.
The Commission seeks comment on the appropriate power limit for the
new internationally harmonized amateur allocation and for the discrete
channels if they are maintained for amateur use. The Commission
tentatively concludes that limiting the radiated power of amateur
stations to 15 W EIRP would reduce the potential of harmful
interference to incumbent primary operations, while maintaining
[[Page 67167]]
consistency with the power limits established internationally for
amateur operations in this band. However, the majority of the amateur
comments are opposed to lower power limits and neighboring countries in
Region 2 permit power levels higher than 15 W EIRP. The Commission
agrees with certain commenters that the long-range propagation
capabilities of these frequencies is likely to allow efficient
communications at low-power levels, but there may be instances where
more power is needed to deal with propagation challenges.
The Commission acknowledges that valid arguments may exist for
adopting power limits above 15 W up to 100 W. For example, Sec.
2.106(b)(133)(ii) (footnote 5.133B or 5.133B), which addresses this
international allocation, outlines a power limit of 20 W EIRP for
Mexico and 25 W EIRP for all Latin American countries and for many
Caribbean countries/territories. Further, a review of the Commission's
licensing database indicates other licenses with higher allocation
status operating at power levels ranging from 15 W up to as high as
5000 W. Accordingly, the Commission seeks to build a more comprehensive
record on the appropriate power limit for 60-meter band amateur
operations. Interested parties seeking a power limit above the proposed
15 W EIRP limit should explain how much power would be appropriate, and
how higher power limits would affect other operations in the 60-meter
band? For example, should the Commission allow the higher power allowed
in other countries in ITU Region 2, such as Mexico and most Caribbean
countries? Should the Commission allow higher power during times of
emergency drills/response or as part of programs where Amateur
licensees support Federal emergency response? Should higher power only
be permitted during disasters or drills supporting disaster relief? If,
going forward, the discrete channels are permitted to be used by
amateur operators under certain parameters or during disasters, what
power limits should apply and when? What other conditions or
considerations should be applied to amateur use of the 60 meter band?
Further, the Commission seeks comment on how the limit should be
specified in the rules. Specifically, should the power limit be defined
in terms of EIRP to be consistent with the WRC-15 recommendation, or
through some other means, such as ERP or transmitter output power?
While some commenters argue that radiated power limits are difficult to
calculate for certain types of antennas, the Commission finds that
amateur licensees are supposed to study the radio arts and should be
capable of determining their operating power. The Commission seeks
comment on the pros and cons of various power limit alternatives and
which method is best for the 60 meter band. If the Commission adopts a
radiated power limit, it does not propose to adopt antenna limitations
because a radiated power limit would ensure that excess power is not
used, and flexibility in antenna choices may lead to spectrum
efficiencies because the signal will propagate in its intended
direction. Nevertheless, the Commission seeks comment on whether, and,
if so what, antenna limitations are appropriate for amateur operations
in this band using these different power limit measurements and how the
Commission's decision could affect how these frequencies would be used
by the amateur community.
Channelization. ARRL and several commenters argued that the new
allocation should not designate sub-bands for various modes of
operation to enable maximum flexibility to avoid interference with
other operations. Janis Carson contended channelization is wasteful
because narrowband modes can operate at less than three kilohertz and
flexibility is need to address prevailing circumstances. She added that
a maximum bandwidth of 500 Hertz should be allowed in the new
contiguous allocation. Charles Powell supported the ARRL request and
contends that amateur equipment is not designed to maintain a high
level of frequency accuracy and that such a design change would make
equipment prohibitively expensive. However, William Springer argued
that the new allocation should be channelized into five 3 kilohertz
channels to promote efficiency and avoid overlapping transmissions.
Benjamin Russell also supported five discrete channels, but suggests
creating ten overlapping channels for narrowband carrier wave (CW) use.
Ronald F Henry contends that channelization would facilitate sharing
with Federal users and, given there are several bands available for
amateur use, the ``60 Meter band must be set aside for emergency
communications as the primary use and as such, channelization is
desired to protect both the primary and secondary user.''
The Commission proposes that the 5351.5-5366.5 kHz band should not
be channelized or have sub-bands. Due to the wide variety of potential
applications and the need to protect other communications, dividing the
band into channels may lead to inefficient spectrum use. However, the
Commission agrees with commenters who state that some wideband digital
emissions could create spectrum sharing problems, and so the Commission
proposes a maximum emission bandwidth of 2.8 kilohertz for amateur
operations in this band. The Commission seeks comment on this proposal
and whether there are other limits or technical rule changes necessary
to ensure reliable and efficient use of this band.
Station Class and Permitted Uses. ARRL and certain other commenters
stated that only amateurs with a General Class license or higher should
be allowed to use the new allocation, because Technician Class license
holders may not have the experience to operate consistent with the
interference avoidance protocols needed for the band. William Springer
opposed the allowance of CW transmissions in the band because he
contends that they are outdated and inefficient, but supported the use
of any commonly-available, unencrypted digital transmission mode
limited by a maximum occupied bandwidth that fits within the channel.
Scott Wright supported the allowance of CW, arguing that several CW
emissions can fit within a small amount of bandwidth. Janis Carson and
Hugh Bahar opposed the allowance of automatically controlled digital
stations and wideband digital modes that could block the entire
allocation and could cause interference without busy channel detection.
In her reply comments, Ms. Carson added that the new allocation should
be used for narrowband digital or CW and that the discrete channels,
along with the one 3 kHz channel contained within the new allocation,
could remain for use of single-side band (SSB) voice or wider digital
modes. Ms. Carson also suggested not allowing any automatic store and
forward email systems in the 60 meter band, claiming that these systems
have a high potential to cause interference due to the ``hidden
transmitter'' effect, where the offshore initiating station cannot hear
a primary user in the skip zone of the shore based relay station.
Finally, W. Lee McVey contended that the 60 meter band rules should
ensure that only publicly documented digital codes operate in the band
to prohibit encrypted communications.
Consistent with the current amateur class requirements for the 60
meter band (see 47 CFR 97.301), the Commission proposes to permit
amateurs holding a General Class license or higher to use the 5351.5-
5366.5 kHz band. The Commission agrees with commenters
[[Page 67168]]
that the long-range propagation characteristics in the band combined
with the need to protect important safety of life communications by
Federal operations potentially requires a higher level of radio
knowledge to ensure the spectrum is properly shared. The Commission
seeks comment on this proposal. Further, if the Commission maintains
the four existing discrete channels at 5332, 5348, 5373, and 5405 kHz
outside of the international allocation, the Commission proposes that
those channels also be permitted for General Class licensees or higher.
The Commission seeks comment on this proposal and other alternatives.
For example, if the Commission adopts the new allocation and keeps the
existing discrete channels, should different amateur classes be
permitted on the new allocation versus the discrete channels? If the
Commission allows station classes below General Class licensees to
access the 60 meter band, what conditions should be applied? For
example, should certain classes be permitted to operate in certain
modes (i.e., voice vs. digital) or at certain times (e.g., only in
response to a disaster)? Given the limited spectral resource at issue,
commenters supporting more flexible use should support their comments
with suggested safeguards or ideas on how the spectrum can be
efficiently used without interfering with primary allocation
operations.
At this time, the Commission does not propose to preclude CW or any
other radio technique currently permitted in the 60 meter band because
the record is inconclusive on whether certain modulation methods should
be prohibited. However, the Commission notes that the amateur rules
generally preclude encrypted operations, and so seeks comment on
whether the 60 meter band rules need to be clearer on what types of
digital operations are permitted. As discussed above, the Commission
proposes to limit the emission bandwidth to 2.8 kilohertz, which may
limit some techniques. The Commission seeks comment on these proposals
and encourages the amateur community to attempt to reach consensus on
what radio techniques should be permitted, given the limited amount of
spectrum available, the need to use this spectrum efficiently, and the
importance of ensuring that the primary users are protected from
harmful interference.
2. Amateur Service in the 420-450 MHz Band
Based on a request from NTIA, the Commission proposes to update the
coordination and contact information in Sec. 2.106(c)(270) (footnote
US270 or US270) for the areas wherein the peak envelope power of an
amateur station operating in the 420-450 MHz (70 cm) band is generally
limited to 50 watts, and to revise the cross reference to footnote
US270 in Sec. 97.313(f) of the rules. The Commission requests comment
on these proposals.
3. Maritime On-Board Communication Stations (457/467 MHz)
The Commission proposes to revise Sec. 2.106(c)(288) (footnote
US288 or US288) to make a limited number of narrowband channels from
the international channel plan adopted at WRC-15 available for use by
on-board communication stations. An on-board communication station is a
low-powered mobile station in the maritime mobile service used for
internal communications on board a ship, or between a ship and its
lifeboats and life-rafts during lifeboat drills or operations, or for
communication within a group of vessels being towed or pushed, as well
as for line handling and mooring instructions. The Commission's
proposals are intended to benefit the maritime industry by making
available a subset of the internationally-harmonized narrowband
channels for on-board communication use while ships are in U.S.
territorial waters. The Commission's overarching goals in making these
proposals are to minimize the potential for intermittent and harmful
interference to stations in the land mobile and fixed services that
operate on the same or adjacent frequencies to on-board communication
stations and to promote more efficient and effective use of the
available spectrum, while fully meeting the operational requirements of
ship station licensees for on-board communication stations.
Sections 2.106(c)(288) and 80.373(g) of the rules make seven
internationally-harmonized frequencies in the 457.5125-457.5875 MHz and
467.5125-467.5875 MHz bands (150 kilohertz) and five other frequencies
available for use by on-board communication stations in U.S.
territorial waters (275 kilohertz in total). Specifically, Sec.
80.373(g)(1) states that the frequencies 457.525 MHz, 457.550 MHz,
457.575 MHz, and 457.600 MHz may be used by on-board repeater stations
and by unpaired on-board mobile stations (i.e., single-frequency
simplex operation) and that four frequencies in the 467.7375-467.8375
MHz band (i.e., 467.750, 467.775, 467.800, and 467.825 MHz) may be used
by on-board mobile stations in two-frequency repeater systems. In
addition, Sec. 80.373(g)(2) states that, where needed, equipment
designed for 12.5 kilohertz channel spacing using the additional
frequencies 457.5375 MHz, 457.5625 MHz, 467.5375 MHz, and 467.5625 MHz
(i.e., channels 12, 14, 22, and 24) may be introduced for on-board
communications; however, no use of these channels is currently
authorized.
WRC-15 revised the international channel plan for on-board
communication stations to provide for 6.25 kilohertz channels. This new
channel plan, shown in table 1 below, specifies 40 frequencies that
support the use of equipment designed to operate on 25, 12.5, or 6.25
kilohertz channels. Channels 1, 2, 3, 12, 14, 22, and 24 as shown in
Table 1 indicate the internationally-harmonized channels that are
currently available for use under the Commission's rules.
[[Page 67169]]
[GRAPHIC] [TIFF OMITTED] TP29SE23.044
To permit the deployment of more spectrally efficient narrowband
equipment, the Commission proposes to revise footnote US288 by
authorizing on-board communication stations to use 12.5 and 6.25
kilohertz channels in the territorial waters of the United States as
described in the following paragraphs.
First, the Commission proposes to revise footnote US288 to
authorize: (1) nationwide use of channels 11-15, which are
internationally-harmonized 12.5 kilohertz channels, for on-board
repeater stations and on-board mobile stations used for single-
frequency simplex operation; (2) on-board mobile stations to operate
nationwide on five non-harmonized frequencies that are 10.225 megahertz
higher in frequency than the center frequency of their associated on-
board repeater stations (frequencies shown in table 2, below); and (3)
on-board repeater stations to operate on channels 12 and 14 and
associated on-board mobile stations operating on channels 22 and 24,
respectively, in the Territorial Sea of the United States and at
coastal ports and the inland ports of Baton Rouge, Houston, and
Portland, and on the waterways and at other ports between these inland
ports and the ocean. The Commission requests comment on these
proposals. The Commission's proposal would make two new frequencies
(467.7625 and 467.7875 MHz) available for use by on-board communication
stations and would authorize the use of eight existing frequencies with
twice the power spectral density (PSD) in their narrower authorized
bandwidth, which increases the potential for harmful interference to
nearby stations of the fixed and land mobile services that also operate
on these frequencies. PSD is defined as the ``power of an emission in
the frequency domain, such as in terms of ERP or EIRP, stated per unit
bandwidth, e.g., watts/MHz.'' 47 CFR 22.99. Currently, the part 80
rules limit the ERP of on-board communication stations in the 456-468
MHz band to 2 watts in a 25 kilohertz channel (80 mW/kHz). If the
Commission authorizes the same ERP in 6.25 kilohertz, then the PSD
would double (160 mW/kHz), thereby increasing the potential for harmful
interference over the signal's bandwidth because the signal's power is
concentrated over a narrower bandwidth. The Commission intends to
address the PSD issue in any subsequent service rules proceeding.

------------------------------------------------------------------------
Second, the Commission proposes to revise footnote US288 to
authorize on-board repeater stations and on-board mobile stations used
for single-frequency simplex operation to operate on the 6.25 kilohertz
channels 102, 121, 122, 141, and 142 and for on-board mobile stations
operating with a repeater station to operate on the 6.25 kilohertz
channels 202, 221, 222, 241, and 242, respectively, in the Territorial
Sea of the United States and at coastal ports and the inland ports of
Baton Rouge, Houston, and Portland, and on the waterways and at other
ports
[[Page 67170]]
between these inland ports and the ocean. The Commission requests
comment on this proposal, noting that eight of these channels overlap
the 12.5 kilohertz channels that the Commission is proposing in the
previous paragraph (i.e., channels 12, 14, 22, and 24) and that
channels 102 and 202 are between low-power part 90 channels. The
Commission requests comment on these proposals, noting that the use of
6.25 kilohertz channels with center frequencies that are offset from
the frequencies used by stations in the fixed and land mobile services
by 6.25 kilohertz are expected to enhance spectrum sharing. The
Commission also solicits comment on whether it should authorize the use
of channel pairs 121/221 on those waterways in the contiguous United
States that the Department of Transportation has designated as part of
America's Marine Highway.
The Commission also proposes to revise the text of footnote US288
to state that, in the territorial waters of the United States, Sec.
2.106(b)(287) (footnote 5.287 or 5.287) applies, except that on-board
communication stations must transmit only on the listed frequencies and
must operate as specified herein. On-board repeater stations and mobile
stations used for single-frequency simplex operation currently may
transmit only in the band 457.5125-457.6125 MHz. The Commission
proposes that the preferred frequencies for repeater systems would be
457.525 MHz (channel 1 or 11), 457.5375 MHz (channel 12), 457.550 MHz
(channel 2 or 13), 457.5625 MHz (channel 14), 457.575 MHz (channel 3 or
15), and 457.600 MHz paired, respectively, with 467.750 MHz, 467.7625
MHz, 467.775 MHz, 467.7875 MHz, 467.800 MHz, and 467.825 MHz; and the
preferred frequencies for single-frequency operations would be those
designated as channels 1-3, 11-15, and 121. Finally, the Commission
proposes that use of channels 122, 141, and 142 and channel pairs 12/
22, 14/24, 102/202, 121/221, 122/222, 141/241, and 142/242 would be
authorized at coastal ports and the inland ports of Houston, Baton
Rouge, and Portland, and along the waterways and at other ports between
these inland ports and the ocean; however, on-board communication
stations would not be able to transmit on these channels while in port
and not underway or preparing to get underway. The Commission seeks
comment on these proposals.
Finally, the Commission proposes to revise Sec. 2.106(c)(287)
(footnote US287 or US287) by allocating the 457.5125-457.6125 MHz,
467.512375-467.518625 MHz, 467.55625-467.56875 MHz, 467.53125-467.54375
MHz, and 467.7375-467.8375 MHz bands (231.25 kilohertz) to the maritime
mobile service on a primary basis, by limiting the use of these
allocations to on-board communication stations, and by stating that, in
these frequency bands, stations in the fixed and land mobile services
may not claim protection from interference caused by on-board
communication stations operating in accordance with US288 and that on-
board communication stations may not claim protection from stations in
the fixed and land mobile services. Alternatively, the Commission
requests comment on whether existing part 90 Private Land Mobile and
part 95 Personal Radio Service licensees operating in the 456-470 MHz
band should be afforded any protection from interference caused by on-
board communication stations operating in accordance with US288. The
Commission observes that the 456-470 MHz band is allocated to the
mobile service on a primary basis in all ITU Regions, and requests
comment on the public interest benefits of both the Commission's
proposal and the alternative.
4. Deletion of the Broadcasting Service From the 700 MHz Band
The Commission proposes to delete the broadcasting service
allocation in the 698-758 MHz, 775-788 MHz, and 805-806 MHz bands from
the non-Federal Table and to revise Sec. 2.106(d)(159) (footnote NG159
or NG159) by removing the reference to part 74, subpart G. Between 1998
and 2010, the Commission transitioned the 698-806 MHz (700 MHz) band
from television broadcasting use (i.e., TV channels 52-69) to public
safety and mobile broadband uses. Currently, the entire 700 MHz band is
allocated to the fixed and mobile services on a primary basis, but the
broadcasting service allocation still remains in the 698-758 MHz, 775-
788 MHz, and 805-806 MHz portions on a primary basis, and licensees in
those bands have the flexibility to provide broadcast services, if they
choose. The Commission requests comment on the Commission's proposal.
In the event that the Commission deletes the broadcast allocation as
proposed, the Commission seeks comment on whether, and which, part 27
service rules should be modified to reflect the change (e.g.,
Sec. Sec. 27.3 (Other Applicable Rule Parts), 27.4 (Terms and
Definitions), 27.10 (Regulatory Status), 27.13 (License Period), 27.50
(Power Limits and Duty Cycle), and 27.55 (Power Strength Limits)).
5. Deletion of Footnote NG155
The Commission proposes to remove Sec. 2.106(d)(155) (footnote
NG155 or NG155) from the rules because the frequencies and frequency
bands to which it applies are not authorized in part 80 of the
Commission's rules. The ITU has identified the frequencies that can
generally be used worldwide for intership communications. Thus, the
Commission tentatively concludes that there is no need to specify any
other frequencies for intership use. The Commission notes that, in the
Second Report and Order in PR Docket No. 92-257 that added footnote
NG155 to the Commission's rules, the Commission declined to adopt the
proposed rules for part 80 regarding maritime sharing of private land
mobile radio frequencies for intership communications. The Commission
requests comments on this proposal.
C. Other Matters
As a result of discussions regarding the protection of near-Earth
operations of deep space missions, WRC-15 added a provision in Article
4 of the Radio Regulations (No. 4.24) to describe the use of space
research service (deep space) allocations. Similarly, the Commission
proposes to add a new paragraph to Sec. 2.102 of the Commission's
rules to clarify that: ``Space research systems intended to operate in
deep space may also use the space research service (deep space)
allocations, with the same status as those allocations, when the
spacecraft is near the Earth, such as during launch, early orbit,
flying by the Earth and returning to the Earth.'' The Commission
requests comment on this proposal.
The Commission proposes to amend Sec. 2.1(c) of the rules to add
or revise the definitions for the terms ``meteorological aids land
station,'' ``meteorological aids mobile station,'' and ``coordinated
universal time'' in accordance with the WRC-15 adopted definitions. The
Commission also proposes to add a definition for the term ``frequency
band'' based on that term's ITU definition. The Commission seeks
comment on these definitions.
The Commission proposes to amend Sec. 2.105(d) of the rules by
stating that the footnote references which appear in the United States
Table below the allocated service or services apply to more than one of
the allocated services, or to the whole of the allocation concerned,
and that the footnote references which appear to the right of the name
of a service are applicable only to that particular service. See the
proposed
[[Page 67171]]
rules for the proposed text of Sec. 2.105(d)(6) through (8), where the
text in paragraph (d)(6) has been moved to paragraph (d)(8).
In response to NTIA's recommendation that the Commission add a
subset of the international footnotes that identify spectrum for
International Mobile Telecommunications (IMT) to the non-Federal Table,
the Commission directed the Chief, Office of Engineering and Technology
to maintain a ``Mobile Broadband Spectrum in the United States'' file
on the ``Radio Spectrum Allocation'' web page. The Commission requests
comment on whether this file meets the public's needs.
Digital Equity and Inclusion. Finally, the Commission, as part of
its continuing effort to advance digital equity for all, including
people of color, persons with disabilities, persons who live in rural
or Tribal areas, and others who are or have been historically
underserved, marginalized, or adversely affected by persistent poverty
or inequality, invites comment on any equity-related considerations and
benefits (if any) that may be associated with the proposals and issues
discussed herein. Specifically, the Commission seeks comment on how its
proposals may promote or inhibit advances in diversity, equity,
inclusion, and accessibility, as well as the scope of the Commission's
relevant legal authority.
Ordering Clauses
Accordingly, it is ordered that, pursuant to sections 1, 4(i),

authorized by the FCC after mutual agreement, on a case-by-case basis,
between the Regional Director of the applicable field facility and the
military area frequency coordinator at the applicable military base. An
Earth station or telecommand station, however, may transmit on the 435-
438 MHz segment with a maximum of 611 W effective radiated power (1 kW
equivalent isotropically radiated power) without the authorization
otherwise required. The transmitting antenna elevation angle between
the lower half-power (-3 dB relative to the peak or antenna bore sight)
point and the horizon must always be greater than 10[deg].
* * * * *
(i) No station may transmit on frequencies in the 60 m band with a
radiated power exceeding 15 W (insert value at order stage). For the
purpose of computing EIRP, the transmitter PEP will be multiplied by
the antenna gain relative to an isotropic antenna. An isotropic antenna
will be presumed to have a gain of 1 (0 dBi). Licensees must maintain
in their station records either the antenna manufacturer's data on the
antenna gain or calculations of the antenna gain.

costs. FSS licensees may require the incumbent to cease operations,
provided that the FSS licensee intends to turn on a system within
interference range of the incumbent, as determined by TIA Bulletin 10-F
or any standard successor. FSS licensee notification to the affected FS
licensee must be in writing and must provide the incumbent with no less
than six months to vacate the spectrum. After the six-month notice
period has expired, the FS licensee must turn its license back into the
Commission, unless the parties have entered into an agreement which

(r) In the bands 17,700 to 19,700 and 24,250 to 25,250 MHz:
Operation of stations using frequencies in these bands is permitted to
the extent specified in this paragraph (r). Licensees, except 24 GHz
band licensees, may use either a two-way link or one frequency of a
frequency pair for a one-way link and must coordinate proposed
operations pursuant to the procedures required in Sec. 101.103. The
use of the band 18.3-19.3 GHz is limited to grandfathered stations.
Licensees in the fixed-satellite service may require that licensees of
grandfathered stations operating in the bands 18.3-19.3 GHz cease
operations in accordance with the provisions in Sec. 101.95. (Note
that stations authorized as of September 9, 1983, to use frequencies in
the band 17.7-19.7 GHz may, upon proper application, continue to be
authorized for such operations, consistent with the
[[Page 67189]]
above conditions related to the 18.3-19.3 GHz band.) Applicants for
one-way spectrum from 17.7-18.3 GHz for multichannel video programming
distribution are governed by paragraph (r)(6) of this section.
Licensees are also allowed to use one-way (unpaired) channels in the
17.7-17.74 GHz sub-band to pair with other channels in the FS portions
of the 18 GHz band where, for example, the return pair is already in
use and therefore blocked or in TDD systems. Stations used for MVPD
operations in the 17.7-17.8 GHz band must coordinate with the Federal
Government before operating in the zones specified in Sec. 1.924(e) of
this chapter.
