Synopsis

Introduction

By this document the Commission amends the United States Table of
Frequency Allocations (U.S. Table) in the Commission's rules to
implement certain radiofrequency (RF) allocation decisions in the Final
Acts of the International Telecommunication Union (ITU) World
Radiocommunication Conference 2015 (WRC-15 Final Acts), make other
allocation changes in the U.S. Table that are not related to WRC-15
Final Acts implementation, and revise parts 2, 25, 74, 78, 87, 90, 97,
and 101 of the rules to reflect the allocation changes.
In this document, the Commission implements certain spectrum
allocation decisions from the WRC-15 Final Acts, which were proposed in
the WRC-15 Notice, including those for amateur radio, satellite
services, and for aural broadcast auxiliary and television broadcast
auxiliary stations. The Commission's decisions are generally divided
into space and terrestrial issues, along with other matters, as
follows.

Satellite Issues

<bullet> Provide satellite-based search and rescue systems
operating in the 406-406.1 MHz band with protection from out-of-band
emissions from operations in adjacent bands by adding footnote US265 to
the U.S. Table and revising section 90.265 to, inter alia, prohibit new
fixed and mobile service frequency assignments in the adjacent 100
kilohertz bands at 405.9-406.0 MHz and 406.1-406.2 MHz. Revise footnote
US13 and section 90.265 to prohibit new assignments for the frequencies
406.1250 and 406.1750 MHz, following the effective date of the rules in
this proceeding.
<bullet> Allocate the 410-420 MHz band to the space research
service (space-to-space) on a secondary basis for non-Federal use,
limited to communications 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.
<bullet> Provide for Global Flight Tracking by allocating the
1087.7-1092.3 MHz sub-band to the aeronautical mobile-satellite (route)
service (Earth-to-space) on a primary basis for Federal and non-Federal
use, limited to space station reception of existing automatic dependent
surveillance broadcast (ADS-B) emissions from aircraft and addition of
paragraph (a)(13) to section 25.202 of the Commission's rules to permit
the licensing of space stations that can receive ADS-B emissions from
aircraft.
<bullet> Add footnote US78 to the 960-1164 MHz band in the Federal
Table and non-Federal Table portions of the U.S. Table to recognize
federal use by military systems for Identification Friend or Foe
operations on center frequencies 1030 MHz (for interrogators) and 1090
MHz (for transponders).
<bullet> Revise footnote US224 to require federal systems that
utilize 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
aeronautical mobile, aeronautical radionavigation, military
identification friend or foe operations, aeronautical mobile satellite,
and radionavigation satellites.
<bullet> Defer consideration of providing 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 the space
research service in the 7190-7235 MHz band.
<bullet> Allocate the 9.2-9.3 GHz band and the 9.9-10.4 GHz band to
the Earth exploration-satellite service (active) on a primary basis for
Federal use and on a secondary basis for non-Federal use.

[[Page 1406]]

<bullet> Revise footnote US128 to support the Department of
Defense's development of pulsed emissions systems in the 10-10.5 GHz
band for the military services.
<bullet> Revise the rules for the 18.142-19.3 GHz, 28.5-29.1 GHz,
and 29.25-29.5 GHz bands as follows. Update footnote US139 and the
related service rules to reflect that incumbent fixed stations in the
18.3-19.3 GHz band no longer have primary status. Raise the secondary
non-Federal fixed-satellite service (space-to-Earth) allocation in the
18.142-18.3 GHz band to co-primary status with the fixed service. Amend
footnote US139 to allow certain fixed stations to continue to operate
indefinitely under existing conditions; revise footnote NG62 to permit
grandfathered fixed stations in the 28.5-29.1 GHz and 29.25-29.5 GHz
bands to operate on a secondary basis to prioritize fixed-satellite
services operating in the band.
<bullet> Delete the primary radionavigation-satellite service
allocation from the 149.9-150.05 MHz and 399.9-400.05 MHz bands.

Terrestrial Issues

<bullet> Allocate the 5351.5-5366.5 kHz (60-meter) band to the
amateur service on a secondary basis; continue to make available on a
secondary basis the four existing channels outside of the 5351.5-5366.5
kHz band; and establish other operating guidelines for amateur use of
the band.
<bullet> Update the coordination and contact information in US270
for amateur stations operating in previously defined areas of the 420-
450 MHz (70 centimeter) band.
<bullet> Delete the broadcasting service allocation in the 700 MHz
band.
<bullet> Delete footnote NG155 from section 2.106 as unnecessary
and inapplicable under the Commission's current rules.

Other Matters

<bullet> Decline the addition of a new paragraph within section
2.102 of the Commission's rules to address certain space research
service (deep space) allocations.
<bullet> Amend section 2.1(c) of the rules to add or revise
definitions in accordance with those adopted at WRC-15. Revise the
radiosonde definition in section 2.1(c) to correct a typographical
error (i.e., correct ``ballon'' to read ``balloon'').
<bullet> Amend section 2.105(d) of the rules to clarify how the
footnote references which appear in the U.S. Table are applicable to
the allocated services in the U.S. Table.

Background

The International Telecommunications Union (ITU) convenes a World
Radiocommunication Conference (WRC) typically every three to four years
to address international spectrum use. Specifically, the WRC allocates
frequency bands to various radio services generally on either a
worldwide or regional basis and enters these radio services in the
ITU's Table of Frequency Allocations (which is reflected in section
2.106 of the Commission's rules as the International Table of Frequency
Allocations) as part of the Radio Regulations. WRC-15 was held in
Geneva, Switzerland from November 2 to November 27, 2015, with more
than 40 topics addressed related to frequency allocation and sharing
for spectrum and orbital resources, with the decisions ultimately
published by the ITU as the WRC-15 Final Acts. On September 10, 2018,
the National Telecommunications and Information Administration (NTIA)
submitted its recommendations for national implementation of the WRC-15
Final Acts to the Commission. This was followed by the Commission's
WRC-15 Administrative Order, which reflected the WRC-15 changes to the
International Table and made other non-substantive, editorial changes
to the Commission's rules, including revisions to the Federal Table
that did not require notice and comment.
The actions taken herein reflect the Notice of Proposed Rulemaking
(WRC-15 Notice), released on April 21, 2023, in which the Commission
proposed to amend the Commission's rules to implement certain of the
remaining allocation decisions from the ITU's WRC-15 Final Acts
concerning portions of the radio spectrum between 5330.5 kHz and 29.5
GHz, make other allocation changes that are not related to WRC-15 Final
Acts implementation, and update the Commission's service rules to
reflect the allocation changes. As of November 28, 2023, the date that
the reply comment period ended in this docket, the Commission received
3,457 filings. Implementation decisions regarding WRC-15 allocations
have also been made in other Commission proceedings.

Satellite Issues

Protection of Search and Rescue Satellites Receiving in the 406-406.1
MHz Band

The Commission's rules currently authorize Emergency-Position
Indicating Radio Beacon, Emergency Locator Transmitter, and Personal
Locator Beacon transmissions in the 406-406.1 MHz band 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.
The Commission adopts proposals addressing concerns that aggregate
levels of electromagnetic interference, including interference from
transmissions in adjacent frequency bands, are adversely affecting the
operations of SARSAT receivers operating in the 406-406.1 MHz band.
These proposals received no comment. First, the Commission adopts the
Commission's proposal for a new footnote US265 in the U.S. Table
(Federal and non-Federal portions) in section 2.106(a) for the 403-410
MHz band to prohibit new frequency assignments within the 405.9-406.0
MHz and 406.1-406.2 MHz bands under the fixed and mobile services
allocations in the 403-406 MHz and 406.1-410 MHz bands. The Commission
adopts its tentative conclusion that medical device radiocommunication
service (MedRadio) operations currently allowed by footnote US64 will
not interfere with SARSAT operations due to their ultra-low power
generation. No commenter disagreed with this tentative conclusion.
Accordingly, the Commission concludes that MedRadio devices can operate
consistent with US265 and their secondary status within the band and
the Commission does not believe that US265's prohibition of new
frequency assignments within the 405.9-406.0 MHz and 406.1-406.2 MHz
bands requires us to restrict MedRadio's continued use and growth
within the 401-406 MHz band. The Commission also adopts its proposal
which states that, in order to protect SARSAT devices, any radiosonde
applicants seeking to operate in the band would need to take into
account frequency drift characteristics when selecting operating
frequencies above 405 MHz to avoid transmitting in the 406-406.1 MHz
band and to take all practical steps to avoid the operating frequency
drifting close to 406 MHz.
The Commission also adopts related proposals regarding fixed and
mobile services in the adjacent 403-406 MHz and 406.1-410 MHz bands.
These proposals also received no comment. First, in the WRC-15 Notice,
the Commission proposed to revise footnote

[[Page 1407]]

US13 and section 90.265 to state that, after the effective date of the
final rules in this proceeding, no assignments for the frequencies
406.1250 MHz and 406.1750 MHz would be made, and that existing stations
could continue to operate indefinitely on these frequencies as they are
currently licensed. The Commission received no comment on this proposal
and therefore revise footnote US13 and section 90.265 as proposed. The
Commission believes that this action will ensure consistency with US265
and help protect SARSAT systems operating in the adjacent 406-406.1 MHz
band from out-of-band emissions (OOBE) originating on the frequencies
406.1250 MHz and 406.1750 MHz. The Commission also adopts the
Commission's proposal to update footnote US117 to 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.

Space Research Service (Space-to-Space) in the 410-420 MHz Band

Current use of the 410-420 MHz band is limited to the fixed,
mobile, and space research (space-to-space) services on a primary basis
for Federal use, with non-Federal use limited to MedRadio operations in
the 413-419 MHz segment of the band. As proposed in the WRC-15 Notice,
the Commission allocates the 410-420 MHz band to the space research
service (space-to-space) on a secondary basis for non-Federal use. The
Commission also adopts footnote 5.268 in the non-Federal portion of the
U.S. Table in the 410-420 MHz band. Footnote 5.268 limits the use of
the space research service to space-to-space communication links with
an orbiting, manned space vehicle, and requires compliance with a power
flux density (PFD) limit at the Earth's surface of -153 to -148 dBw/
m\2\ in a 4-kilohertz bandwidth, depending on the angle of arrival of
the radio-frequency wave, to protect existing and future fixed and
mobile services operations from harmful interference.
These proposals received no comment and the Commission concludes
that allocating the 410-420 MHz band to the space research service
(space-to-space) on a secondary basis for non-Federal use will support
both increased commercial exploration of the deep space environment and
protect primary Federal operations in this band. Additionally, the
adoption of footnote 5.268 restricts the use of this band to
communications links with an orbiting, manned space vehicle and limits
the PFD at Earth's surface, which will protect stations of the primary
fixed and mobile services bands from harmful interference.

Global Flight Tracking for Civil Aviation (1087.7-1092.3 MHz)

The Commission adopts proposals intended to enhance global flight
tracking capabilities. First the Commission adopts its proposal to
allocate the 1087.7-1092.3 MHz band to the aeronautical mobile-
satellite (route) service (Earth-to-space) on a primary basis for
Federal and non-Federal use, limited to space station reception of
automatic dependent surveillance-broadcast (ADS-B) emissions from
aircraft by referencing footnote 5.328AA in the 960-1164 MHz band
within the U.S. Table. ADS-B is a service that automatically broadcasts
GPS-derived data on the location, velocity, altitude, heading, and
other performance metrics, of an ADS-B-equipped aircraft to other ADS-
B-equipped aircraft and ground stations for distribution to air traffic
control systems. Pursuant to Federal Aviation Administration
regulations, after January 1, 2020, virtually all aircraft must be able
to transmit ADS-B information (ADS-B Out) to fly in most controlled
airspace. For aircraft that operate above 18,000 feet or need to comply
with ADS-B requirements outside the United States, the equipment must
operate on the frequency 1090 MHz using what are often referred to as
1090ES transponders. All other aircraft may carry equipment operating
either on frequency 978 MHz or frequency 1090 MHz. In 2006, the
Commission adopted technical and operational rules for ADS-B
transmissions on 978 MHz using Universal Access Transceiver (UAT)
technology. While the Commission authorized the use of the frequency
1090 MHz by aeronautical utility mobile stations used for airport
surface detection in 2013, it has not adopted technical and operational
rules specifically for airborne ADS-B transmissions on 1090 MHz.
However, part 87 accommodates the use of 1090 MHz aeronautical utility
mobile stations as airborne electronic aids to navigation in the 960-
1215 MHz band.
The Commission adopts the proposed implementation of the primary
aeronautical mobile-satellite (route) service allocation, limited to
space station reception of automatic dependent surveillance-broadcast
(ADS-B) emissions from aircraft, by referencing footnote 5.328AA in the
960-1164 MHz band within the U.S. Table (Federal and non-Federal
Tables). Under section 87.5 in the Commission's aviation service rules,
ADS-B is currently defined as broadcast transmissions from aircraft,
supporting aircraft-to-aircraft or aircraft-to-ground surveillance
applications, including position reports, velocity vector, intent and
other relevant information about the aircraft. To reflect this enhanced
ADS-B capability in the aviation service rules, the Commission modifies
the definition of ADS-B in section 87.5 to include space station
reception of automatic dependent surveillance-broadcast (ADS-B)
emissions from aircraft in the 1087.7-1092.3 MHz band. Additionally,
the Commission adds paragraph (a)(13) to section 25.202 of the
Commission's rules to permit the licensing of space stations that can
receive ADS-B emissions in the 1087.7-1092.3 MHz band from aircraft.
The new primary aeronautical mobile-satellite (route) service (Earth-
to-space) allocation that the Commission adds in section 2.106(a) will
extend reception of ADS-B signals beyond terrestrial line-of-sight to
facilitate reporting the position of aircraft located anywhere in the
world. As aircraft travel over land, there are generally terrestrial
networks capable of forwarding this information to flight control
centers. When travelling over an ocean or other remote regions,
however, space stations can provide an alternative ADS-B point of
reception.
Iridium, in its comments, supports the Commission's proposal to
create a primary allocation in the band for Earth-to-space ADS-B
transmissions from aircraft. Further, Iridium suggests that the
Commission should automatically upgrade to primary status existing
Earth-to-space authorizations in the band, such as those in its second-
generation satellite authorization. No commenter opposed this proposal.
The Commission agrees with Iridium and conclude that providing a
primary allocation for satellite reception of ADS-B signals from
aircraft-in-flight would ensure the efficient management of air traffic
in oceanic, polar, and remote airspace. The use of ADS-B directly
influences many factors, such as the minimum separation distances
between aircraft, resulting in the efficient use of airspace,
optimization of air routes, and altitude availability due to events
such as changes in weather conditions. Regarding Iridium's request that
existing Earth-to-space operations in this band, such as those in
Iridium's second-generation satellite authorization, automatically be
upgraded to primary status, the Commission directs Iridium to the terms
of its waiver grant. Specifically, the Commission stated as a condition
of licensing Iridium's second-generation satellites that ``[o]perations
in the 156.0125-162.0375 MHz and 1087.7-

[[Page 1408]]

1092.3 MHz bands must be in accordance with any Commission rulemakings
subsequent to the release of this Order and Authorization that
implement any new domestic allocations or service rules for these
bands.'' As the Commission's rule today allocates the 1087.7-1092.3 MHz
band to the aeronautical mobile-satellite (route) service (Earth-to-
space) on a primary basis for Federal and non-Federal use, Iridium's
existing ADS-B satellite operations in this band would, under the terms
of the waiver, also attain primary status within this band.
As proposed, the Commission also adds new footnote US78 to the 960-
1164 MHz band in the U.S. Table in section 2.106(a) to recognize
Federal use by military systems for Identification Friend or Foe (IFF)
operations on center frequencies 1030 MHz (for interrogators) and 1090
MHz (for transponders). This proposal, suggested by NTIA, did not
result in any comments. This use will be subject to the condition that
harmful interference not be caused to the aeronautical radionavigation
service or the aeronautical mobile (R) service. The Commission believes
that this use will enhance the ability of military aircraft to
determine whether other aircraft are friendly in nature.
Lastly, as proposed, the Commission revises footnote US224 to
require Federal systems that utilize spectrum spread 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 (route) and aeronautical
radionavigation services in the 960-1164 MHz band, Federal IFF systems
on center frequencies 1030/1090 MHz, aeronautical mobile-satellite
(route) 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 believes that this footnote revision is necessary to protect
the increased number of services operating in the aforementioned bands.
Although updates to its part 87 rules were not specifically proposed in
the WRC-15 Notice's rule parts list, the Commission did request comment
on whether modifications to its part 87 rules were necessary to
implement any of the proposed changes. The Commission received no
comment but conclude that, in order to fully implement its decision,
the Commission must revise section 87.479 of the Commission's rules to
reflect the additional aviation services that will now be entitled to
protection that footnote US224 provides to part 87 radionavigation
services in the 960-1215 MHz band.

Satellite Uplinks in the 7190-7250 MHz Band

In the WRC-15 Notice, as recommended by NTIA, the Commission sought
comment on whether it should provide spectrum on a secondary basis for
non-Federal Earth-to-space operations for the Earth exploration-
satellite service in the 7190-7250 MHz band and the space research
service in the 7190-7235 MHz band. In the U.S. Table, the 7190-7235 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 services (Earth-to-space)
exclusively for Federal use. For the reasons discussed below, the
Commission declines to address these spectrum bands herein and are
deferring a decision for future Commission action.
The Commission specifically sought comment on making 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 by adding footnotes US460 and 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. Commenters express concern with these
proposals. NCTA, in its comments, states that ``[t]he circumstances of
the 7/8 GHz range have changed significantly since the Commission
issued the NPRM in April 2023 and even more since NTIA made its
original recommendation to the Commission in 2018. Qualcomm states that
moving now to allocate these sub-bands ``would further complicate the
spectral landscape that has been earmarked for domestic study and
potentially international studies under the ITU-R working groups.''
Multiple commenters cite the National Spectrum Strategy (NSS) to
assert that additional allocations in the 7/8 GHz band could complicate
future allocation decisions. One of the spectrum bands identified is
the 7125-8400 MHz band, which the NSS states ``will be studied for
wireless broadband use'' (on a licensed and/or unlicensed basis),
though, as NTIA states in the strategy, ``some sub-bands eventually may
be studied for other uses.'' It goes on to state that there are a
variety of mission-critical Federal operations in this band (including
Fixed, Fixed Satellite, Mobile, Mobile-Satellite, Space Research, Earth
Exploration-Satellite, and Meteorological-Satellite Services) that
would make it challenging to repurpose portions of the band while
protecting incumbents from harmful interference.
CTIA states that any proposal to allocate the ``7190-7235 MHz band
to the Space Research Service and the 7190-7235 MHz band to the Earth
Exploration Satellite-Service on a secondary basis for non-Federal use
has been overcome by the NSS and a series of additional events since
WRC-15's conclusion and NTIA's submission to the Commission of its WRC-
15 Final Acts implementation recommendations.'' CTIA goes on to state
that the 7/8 GHz spectrum range is vital ``to the 7-16 GHz band that
Chairwoman Rosenworcel has identified for 6G and that the ITU is
expected to explore this spectrum range for next-generation wireless
deployments.'' T-Mobile states that the Commission should refrain from
taking any action that would ``limit its options regarding the use of
these bands for future wireless services.''
Lockheed Martin, however, states in its comments that
``implementing only a secondary non-Federal allocation domestically [in
support of deep-space operations] poses the risk of rendering the band
unusable for future non-Federal operations absent adequate
protections.'' Lockheed encourages the Commission to instead make the
allocation on a primary basis in the Table of Allocations.
In light of ongoing governmental workstreams reviewing the band,
changes in the spectral environment, and opposition from stakeholders
across multiple sectors, the Commission finds it premature to reach a
decision at this time on additional allocations in this band. The
Senate Commerce Committee's budget reconciliation bill proposes that
the NTIA conduct a timely spectrum analysis of the 7.25-7.4 GHz band in
support of the House's budget reconciliation bill which outlines the
Administration's effort to identify and auction 600 megahertz of
spectrum for advanced mobile and fixed broadband services. Lawmakers
have identified the 7/8 GHz band in

[[Page 1409]]

particular as warranting consideration for future spectrum auctions.
While the Commission recognizes the importance of the space exploration
mission being undertaken by NASA and its commercial partners, the
information received in the record indicates that moving ahead with
allocations in these bands at this time could complicate studies of the
bands for advanced wireless uses.

Earth Exploration-Satellite Service (Active) in the 9.2-9.3 GHz and
9.9-10.4 GHz Bands

The Commission adopts its proposals to allocate 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 four footnotes: 5.474A, 5.474B, 5.474C, and
US474D. These proposals 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 an additional 600
megahertz of spectrum in the adjacent bands to this service and support
the growing demand for greater image resolution to satisfy global
environmental monitoring requirements while protecting adjacent-bands
services from any interference issues this increase in usage may cause.
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.
In the WRC-15 Notice, the Commission sought comment on whether to
allocate 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 the
conditions of four footnotes added to the 9.2-9.3 GHz and 9.9-10.4 GHz
bands (5.474A, 5.474B, 5.474C, and US474D). Footnote 5.474A limits the
use of the 9.2-9.3 GHz and 9.9-10.4 GHz bands 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. Footnote 5.474B states that stations in the Earth
exploration-satellite service (active) shall comply with Recommendation
ITU-R RS.2066-0 (WRC-15), which provides an operational procedure to
avoid main-beam to main-beam coupling between Earth exploration-
satellite service systems when transmitting near 9.6 GHz and radio
astronomy service stations performing observations in the 10.6-10.7 GHz
band. Footnote 5.474C states that stations operating in the Earth
exploration-satellite (active) service shall comply with Recommendation
ITU-R RS.2065-0 (WRC-15), which provides mitigation techniques that can
reduce the unwanted emissions of Earth exploration-satellite service
(active) systems to avoid interference with space research service
(space-to-Earth) links in the 8.40-8.45 GHz and 8.45-8.50 GHz bands.
Lastly, footnote US474D (based partially on footnote 5.474D) would
require that stations in 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. The Commission also
sought 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 that the status of those non-
Federal allocations would mirror the status of the Federal Earth
exploration satellite-services (active) in those bands. The Commission
received no comment on these proposals.
The Commission adopts the proposal to allocate 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 the four aforementioned footnotes (5.474A,
5.474B, 5.474C, US474D). The Commission believes that this allocation
will support the growing demand for scientific and geoinformation
applications for both the Federal and non-Federal operations. Further,
the application of the four footnotes to these bands will protect
adjacent services from any interference issues this increase in usage
may cause. Lastly, the Commission declines to adopt its proposal to
allocate the 9.2-9.8 GHz and the 9.9-10.4 GHz bands to the Earth
exploration satellite-service (active) on a primary basis for non-
Federal use so the status of these allocations would mirror the status
of the primary Federal Earth exploration satellite-service (active)
allocations in these bands, as the Commission believes that the non-
Federal secondary allocation the Commission adopts today in the 9.2-9.3
GHz and 9.9-10.4 GHz bands will provide non-Federal users with
sufficient bandwidth for their operations. Declining to raise the
status of the secondary non-Federal Earth exploration satellite-service
(active) allocations in these bands to primary status will also help
protect adjacent-band operations from harmful interference, as the
proposed non-Federal primary allocation was not subject to footnotes
5.474A, 5.474B, 5.474C, and US474D, which the WRC-15 Final Acts
prescribed to protect adjacent services from increased EESS usage in
the 9.2-9.3 GHz and 9.9-10.4 GHz bands.
The Commission also proposed to revise footnote US128 to support
the Department of Defense's (DOD) development of pulsed emissions
systems for the military services in the 10-10.5 GHz band. The 10-10.5
GHz band is currently allocated to the radiolocation service on a
primary basis for Federal use; the 10-10.45 GHz band is allocated to
the amateur and radiolocation services on a secondary basis for non-
Federal use; the 10.45-10.5 GHz band is allocated to the amateur,
amateur-satellite, and radiolocation services on a secondary basis for
non-Federal use; and the 9.975-10.025 GHz band is allocated to the
meteorological-satellite service on a secondary basis for use by
weather radars for Federal and non-Federal use. US128 currently
prohibits pulsed emissions in the 10-10.5 GHz band, except for weather
radars onboard meteorological satellites in the 10-10.025 GHz sub-band.
The Commission received no comments on this proposal and revise
footnote US128 to permit DOD's development of pulsed emissions systems
for the military services in the 10-10.5 GHz band to help meet future
system needs.

Revision of the 18.142-19.3 GHz, 28.5-29.1 GHz, and 29.25-29.5 GHz
Bands

The Commission sought comment in the WRC-15 Notice on revising
footnote NG62 to permit grandfathered fixed stations in the 28.5-29.1
GHz and 29.25-29.5 GHz bands to operate on a secondary basis; updating
footnote US139 and the related service rules to reflect that incumbent
fixed stations in the 18.3-19.3 GHz band no longer have primary status;
raising the secondary non-Federal fixed-satellite service (space-to-
Earth) allocation in the 18.142-18.3 GHz band to co-primary status with
the fixed service; and amending US139 to allow certain fixed stations
to continue to operate indefinitely under existing conditions.
First, the Commission revises footnote NG62 to permit grandfathered
fixed stations to operate on a secondary basis in the 28.5-29.1 GHz and
29.25-29.5 GHz bands, which prioritizes fixed-satellite services
operating in the band. Footnote NG62 currently states that, in the
28.5-29.1 GHz and 29.25-29.5 GHz bands, stations in the fixed-satellite

[[Page 1410]]

service shall not cause harmful interference to, or claim protection
from, stations in the fixed service operating under 18 listed call
signs. The Commission proposed to amend footnote NG62 to permit fixed
stations authorized pursuant to the 10 listed call signs that currently
operate in these bands to continue to operate indefinitely on a
secondary basis. The Commission adopted NG62 when it deleted the
primary fixed and mobile service allocations from the 28.35-29.1 GHz
and 29.25-29.5 GHz bands in the non-Federal Table of Frequency
Allocations. The Commission additionally notes that 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. Only one commenter, Iridium,
addresses this proposal. Iridium contends that when the Commission
adopted its Ka-band (29.1-29.5 GHz) plan in 2017, it plainly intended
for the band to be used primarily for satellite feeder links. Iridium
further states that the proposal would clearly establish the status of
the grandfathered terrestrial stations by stating that they are
secondary to satellite operations in the 29.1-29.5 GHz band. Given the
fact that only 10 of the 18 legacy fixed stations continue to operate
in the band, amending NG62 to prioritize satellite operations
ultimately rationalizes the relative priorities for services in the
28.5-29.1 GHz and 29.25-29.5 GHz bands.
As proposed, the Commission amends footnote US139 to state 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 section 101.95 of the Commission's rules. The Commission
made 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. The Commission also proposed to revise
sections 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. While most of the
proposed changes would remove channels that are no longer allocated to
the fixed service, in one instance the Commission proposed to add
replacement channels, i.e., the Commission proposed replacing the 12
frequency pairs in section 74.502(c)(1)(i) of the rules with the 5-
megahertz channels from section 101.147(r)(5). The Commission also
proposed to update sections 101.95(a) and 101.147(a) to remove expired
text and to remove sections 101.83 through 101.91 and 101.97, which
concern expired policies governing fixed service relocation from the
18.3-19.3 GHz band. The Commission received no comment on these
proposals and, due to the absence of both a fixed allocation and the
lack of any primary grandfathered fixed stations operating in the band,
the Commission amends its rules to update the 18.3-18.9 GHz band as
proposed. The Commission will also revise sections 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. Lastly, the Commission will adopt its proposal to replace the
12 frequency pairs in section 74.502(c)(1)(i) of the rules with 5-
megahertz channels from section 101.147(r)(5), as well as make the
aforementioned updates to section 101.91 and 101.97 to remove expired
language.
The Commission also adopts its proposal to raise the non-Federal,
secondary fixed-satellite service (space-to-Earth) allocation in the
18.142-18.3 GHz band to co-primary status (co-equal with the non-
Federal fixed service allocation in the band). This upgrade in
allocation status provides receiving earth stations with interference
protection from later-licensed fixed stations 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 received no
comment on this proposal and adopt it based on its conclusion that this
upgrade in allocation status will result in earth station's using this
band more intensely and enhanced spectrum efficiency. This action to
raise the non-Federal secondary FSS (space-to-Earth) allocation in the
18.142-18.3 GHz band to primary status also aligns with NTIA's
recommendation in the 18 GHz Band Report, which identified the 18 GHz
band for expanded Federal and non-Federal satellite operations,
consistent with the U.S. position at WRC-23.
Lastly, the Commission sought comment on whether it should allow
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 to revise
footnote US139 to codify that these fixed stations may continue to
operate indefinitely under existing conditions. Again, the Commission
received no comment on these proposals and thereby allow continued
operation of the aforementioned fixed stations and codify footnote
US139, allowing continued, indefinite operation of these stations under
existing conditions.

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 and as proposed in the WRC-15
Notice, the Commission remove the radionavigation-satellite service
allocation in the 149.9-150.05 MHz and 399.9-400.05 MHz bands from the
Federal and non-Federal portions of the U.S. Table. These two bands are
allocated to the mobile-satellite service (Earth-to-space) and the
radionavigation-satellite service, both on a primary basis, for Federal
and non-Federal use. The WRC-15 Final Acts deleted the radionavigation-
satellite service allocations from the International Table in these
bands because they expired on January 15, 2015, pursuant to footnote
5.224B. The Commission received no comment on this proposal. A search
of the Commission's International Communications Filing System (ICFS)
database revealed that that there are no RNSS licensees in the two
bands. Thus, the Commission deletes the radionavigation-satellite
service allocation from the two bands and retain the existing primary
allocations to the mobile-satellite service (Earth-to-space) in the two
bands on an exclusive basis, consistent with the WRC-15 Final Acts.

Terrestrial Issues

Amateur Service in the 5351.5-5366.5 kHz Band

In this section, the Commission makes allocation decisions
regarding amateur use of the 5351.5-5366.5 kHz band and the four
discrete channels at 5332, 5348, 5373, and 5405 kHz that are outside of
the band, as well as the technical and operational characteristics
amateurs

[[Page 1411]]

must adhere to when utilizing the band and the four discrete channels.
The WRC-15 Final Acts allocated the 5351.5-5366.5 kHz band to the
amateur service on a secondary basis in all ITU regions and generally
set a maximum radiated power at 15 watts equivalent isotropically
radiated power (EIRP), equivalent to 9.15 watts effective radiated
power (ERP). In the WRC-15 Notice, the Commission sought comment on a
number of proposals affecting amateur use of this band, including
whether to allocate the 5351.5-5366.5 kHz band to the Amateur Radio
Service on a secondary basis, whether the amateur service should keep
the existing four channels at 5332, 5348, 5373, and 5405 kHz they use
that are outside of the new allocation (known by amateurs as the 60-
meter band), whether use and power limitations should be applied to the
band, and the appropriate station class for use of the band, among
others.
Under current Commission rules, the 5275-5450 kHz band is allocated
for Federal/non-Federal shared use to the fixed service on a primary
basis and the mobile except aeronautical mobile service on a secondary
basis. Footnote US23 provides the amateur service with a secondary
allocation on five discrete channels--each with a maximum bandwidth of
2.8 kilohertz and centered on frequencies 5332, 5348, 5358.5, 5373, and
5405 kHz. Current Commission rules also allow stations in the amateur
service to transmit on these frequencies with a maximum ERP of 100 W
peak envelope power (PEP)--over ten times more powerful than WRC-15's
EIRP limit.
In 2017, the American Radio Relay League (ARRL), filed a Petition
for Rulemaking asking the Commission to implement the amateur
allocations provided for in the WRC-15 Final Acts, to retain the four
amateur service channels outside of the band, to authorize amateurs
General Class or above to use the contiguous band, and to retain the
maximum ERP limit of 100 W PEP for use in the new band. NTIA recommends
that the Commission conforms 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 of
this proposed new amateur band, and restricting the maximum radiated
power of amateur operations in the band to 15 W EIRP (9.15 W ERP).
Allocation. For the reasons stated below, the Commission modifies
footnote US23 and part 97 of the Commission's rules to implement the
new international allocation at 5351.5-5366.5 kHz, retain the existing
four channels at 5332, 5348, 5373, and 5405 kHz that are outside of the
new allocation, and do not restrict the existing secondary allocation
for the existing four channels to disaster response operations. The
Commission first sought comment on the proposal to modify footnote US23
and part 97 of the Commission's rules to implement the new
international allocation at 5351.5-5366.5 kHz and whether to retain the
existing four channels at 5332, 5348, 5373, and 5405 kHz that are
outside of the new allocation. While commenters support the new
international allocation, they are generally opposed to the removal of
the four discrete channels outside of the new allocation. A commenter
states that the ``propagation characteristics of the 60-meter band
allow for more reliable communications over medium distances than other
amateur bands such as the 80-meter or 40-meter bands.'' Another
commenter states that the ``60-meter band has proven to be immensely
valuable in facilitating public service initiatives. Its strategic
positioning between the 80-meter and 40-meter amateur bands ensures
reliable signal propagation to specific geographic areas, particularly
during temporal and solar cycle fluctuations.'' Commenters generally
aver that the amateur radio community requires access to a range of
frequencies in order to achieve long-distance propagation by refracting
high frequency communications off of the ionosphere. Commenters
additionally note that, depending on atmospheric conditions, signals
transmitting at lower frequencies, such as the 3500-4000 kHz band, can
be absorbed by the ionosphere. Conversely, there are atmospheric
conditions such that operation at higher frequencies, for example the
7000-7300 kHz range, could result in signals that pass through the
ionosphere completely, avoiding the desired refraction necessary for
long distance reception. Multiple commenters thus took issue with the
Commission's statement in the WRC-15 Notice, which characterized the
internationally harmonized spectrum options at 3 and 7 MHz as being
sufficient for amateur operations, with most commenters reiterating the
different propagation characteristics of the bands.
In 2003, when the Commission originally granted amateurs a
secondary allocation in the 5250-5400 kHz range, the Commission stated
its belief that frequencies within that range might be useful for
completing disaster communications links at times when the 3 and 7 MHz
bands were not available due to ionospheric conditions. The Commission
continues to hold that opinion and thus allocate the 5351.5-5366.5 kHz
band to the amateur radio service by modifying footnote US23 and part
97 of the Commission's rules. Additionally, the Commission retains the
existing four channels at 5332, 5348, 5373, and 5405 kHz that are
outside of the new allocation for continued amateur use.
The Commission also sought comment on whether it should
alternatively only allow amateur access to the four discrete channels
at 5332, 5348, 5373, and 5405 kHz in response to disasters. Amateurs
participating in the Military Auxiliary Radio System (MARS) or SHAred
RESources (SHARES) High Frequency (HF) Radio programs during disasters
or the Amateur Radio Emergency Service (ARES) or the Radio Amateur
Civil Emergency Service (RACES) emergency communications programs were
invited to share their proposals for whether the existing channels
should continue to be used and under what conditions. One commenter
states that utilization of the 60-meter band channels allows the
amateur community to receive up to date emergency communications from
MARS stations. On the other hand, another commenter states that use of
the 60-meter band should be conditioned upon use for practice drills in
MARS, SHARES, ARES, and RACES and that non-emergency use should not be
allowed. However, most commenters on this issue do not support
restricting the band to emergency use and some state that, while
emergency use of the band by qualified amateurs remains important, non-
emergency use gives amateurs an important frequency band for continued
communications. The Commission finds that restricting the existing
allocation to disaster response would deprive the amateur community of
an important means of communication, especially in instances where
ionospheric propagation characteristics at alternative high frequency
bands render them potentially unusable.
Channelization and Permitted Uses. Consistent with its proposal in
the WRC-15 Notice, the Commission does not require the use of
channelization or sub-bands in the new internationally harmonized
amateur allocation. In the WRC-15 Notice, the Commission stated that,
due to the wide variety of potential applications and the need to
protect other communications, dividing the band into channels or sub-
bands would lead to inefficient spectrum use. The Commission also
proposed that, due to

[[Page 1412]]

the propensity of some wideband digital emissions creating spectrum
sharing problems, a maximum emission bandwidth of 2.8 kilohertz should
be imposed on amateur operations in the band. The Commission asked
commenters whether there were any other limits or technical rule
changes necessary to ensure reliable and efficient use of the band.
Most commenters support the Commission's proposal not to channelize
the new international allocation, with one stating that channelization
in the amateur radio service is limiting due to the varying nature of
emissions depending on type (e.g., continuous wave, phone, or digital).
Another commenter, however, supports the notion of channelization,
stating that the new 15 kilohertz band can be neatly channelized into
five, 3-kilohertz channels, which would help to maintain order by
letting users know where transmissions must occur. Regarding other
technical proposals for the band, another commenter argues against the
use of continuous wave (CW) transmissions, stating that they are
obsolete and have not been used for primary communications in other
radio services for years. On the other hand, another commenter argues
that the new 15 kilohertz band should not be channelized and should be
restricted to narrow modes only, such as CW and digital, with no phone
mode allowed on the new band. One commenter expresses support for the
Commission's proposal not to channelize the new 15 kilohertz band and
states that any unencrypted digital operation should be allowed as long
as its emission bandwidth does not exceed 2.8 kilohertz, which the
commenter maintains is necessary to preserve spectrum in this narrow
band. Other commenters also support the Commission proposal to limit
emission bandwidth to 2.8 kilohertz within the new band.
Due to the limited contiguous allocation of 15 kilohertz, the
Commission recognizes that amateur radio operators will need
flexibility to utilize the new allocation. Thus, the Commission does
not require the use of channelization or sub-bands in the new
allocation at 5351.5-5366.5 kHz. The Commission also carries forward
the requirement of section 97.303(h) of the Commission's rules,
currently applicable to the discrete channels at 5332, 5348, 5373, and
5405 kHz, which stipulates that amateur operators shall ensure that
emission bandwidth not exceed 2.8 kilohertz, which the Commission also
agrees will preserve access to the limited spectrum in this secondary
allocation. Amateurs utilizing the discrete channels located at 5332,
5348, 5373, and 5405 kHz should already be familiar with these
requirements and they have been quite successful in the mitigation of
interference to primary users. The Commission found the comments that
favored channelization to be unpersuasive, due to both the record
reflecting substantial opposition to channelization and the fact that
narrow band modes of operation allow a multitude of signals to transmit
on a single 2.8 kilohertz channel.
Station Class. The Commission limits use of the existing amateur
allocations at 5332, 5348, 5373, and 5405 kHz and the new amateur
allocation at 5351.5-5366.5 kHz to amateur radio operators holding a
General Class license or higher. The Commission proposed in the WRC-15
Notice that utilization of the new international allocation at 5351.5-
5366.5 kHz should be limited to amateurs holding a General Class
license or higher. The Commission also sought comment on its proposal
that if it maintains the four discrete channels at 5332, 5348, 5373,
and 5405 kHz outside of the international allocation, should they too
be limited to General Class licensees or higher. Commenters support the
Commission's proposal to limit use of the new 15 kilohertz band to
General Class licensees or above, with one stating that it is necessary
``due to the narrowness of the band, the need to calculate radiated
power limits for the antenna configuration, and the need to understand
the requirements ensuring that primary users are protected from harmful
interference.'' ARRL also suggests that use of the new international
allocation and the four channels outside of that allocation should be
limited to General Class licensees or higher, as ``[e]ntry-level radio
amateurs may not have the requisite experience to operate in accordance
with the interference avoidance protocols with which much more
experienced licensees will be proficient.''
The Commission agrees with commenters that utilization of the new
international allocation at 5351.5-5366.5 kHz should be limited to
those holding a General Class license or above. The Commission believes
that the need to protect the important Federal operations in this band
requires a higher level understanding of power limitations,
radiocommunications technology, operating practices, and applicable
regulations. Those holding General Class licenses or above will have a
better understanding of these requirements. Further, this logic extends
to the four discrete channels that are outside of the 5351.5-5366.5 kHz
band, and the Commission limits utilization of these frequencies to
those holding a General Class license or higher.
Power. For the reasons stated below, the Commission does not allow
the amateur community to utilize the new international allocation at
5351.5-5366.5 kHz at the requested 100 W ERP limit and adopt NTIA's
proposal to limit usage of this band to 15 W EIRP, or 9.15 W ERP.
Operating on a secondary basis, the amateur community must protect
Federal operations in this band, and the Commission does not believe
that the increased potential for harmful interference at this power
limit has been fully considered at this time. Amateur access to the
four discrete channels at 5332, 5348, 5373, and 5405 kHz will however,
continue at the same 100 W ERP limit. In the WRC-15 Notice, the
Commission tentatively concluded that NTIA's recommended 15 W EIRP
limit would reduce the potential of harmful interference to incumbent
primary operations and that the long-range propagation capabilities of
the frequencies in question would likely allow efficient communications
at low-power levels. The Commission did, however, concede that there
may be instances where more power is needed to deal with propagation
challenges. The Commission asked commenters seeking a power limit above
the proposed 15 W EIRP to explain the appropriate power limit for the
60-meter band, if higher power levels should only be maintained during
emergency drills/response, how the power limit should be defined in the
Commission's rules (EIRP, ERP, or transmitter output power), and
whether antenna limitations were necessary.
In line with ARRL's Petition for Rulemaking and proposed retention
of the 100 W ERP limit for both the 15 kilohertz band at 5351.5-5366.5
kHz and the four discrete channels at 5332, 5348, 5373, and 5405 kHz
outside of the new allocation, most commenters argue against the
proposed power reduction. Many point out that Canada has already
enacted the proposals ARRL has put forth in this proceeding, namely
retention of the 100 W ERP limit for the 60-meter band, and that
identical allocations and power limits would facilitate harmonious
communications throughout most of North America. Commenters argue that
the 100 W ERP limit currently in place for the 60-meter band is
necessary to maintain reliable communications, while others state that
the current power limit is necessary for emergency communications when
propagation on other bands is limited by

[[Page 1413]]

solar and earth conditions. Others argue for an even larger power
increase, asking the Commission to consider a 500 W ERP limit, ``since
lower frequencies are more susceptible to D-layer absorption and
emergency communications will still need to be heard, especially in
high latitude locations like Alaska.'' Consistent with most commenters,
however, is the contention that the current use of the 100 W ERP limit
on the 60-meter band has not been shown to cause harmful interference
to the primary users of the band, both in assigned channels and through
spurious emissions outside of the allocation. Some commenters argue
that, due to the use of newer and more efficient digital modes, weak
signals are not an impediment to sending information and the 15 W EIRP
limit proposed by the NTIA is sufficient. Others, however, state that
amateur, non-emergency operations conducted in the four discrete
channels outside of the new allocation should be restricted to the 15 W
EIRP limit and that, aside from practices and drills, these channelized
frequencies should not be used by the amateur community unless an
actual emergency exists, at which point the 100 W ERP limit would be
appropriate. Another commenter states that stipulating power levels
based on scenario (emergency/non-emergency, drills, etc . . .) would
overcomplicate the issue. Lastly, many commenters oppose the
Commission's proposal to define the power limit in terms of EIRP to be
consistent with the WRC-15 recommendation, with one commenter stating
that EIRP measurements are applicable to important communication links
and multi-node networks--not amateur radio. Another commenter further
states that the measuring standard should remain as ERP, instead of
EIRP, as the ERP standard is widely used and understood in the amateur
radio service. One commenter argues that if an appropriate power
standard such as EIRP or ERP is used, then no antenna limitations are
necessary.
The Commission agrees with those commenters that support the
proposed 15 W EIRP (9.15 W ERP) for the new international allocation at
5351.5-5366.5 kHz, in line with the WRC-15 Final Acts and the
Commission's tentative conclusion in the WRC-15 Notice. However, for
consistency in part 97 and the power specification for the discrete
channels the Commission is leaving in place, the Commission specifies
the power limit as 9.15 W ERP, which is equivalent to 15 W EIRP.
Additionally, as stated above, allowing amateur operations in this band
while fully protecting incumbent primary Federal operations is the
Commission's priority, and even intermittent interference in this band
could jeopardize important Federal operations. Also, the long range
propagation characteristics of this band should allow for efficient
communications even at low-power levels. Given, however, that ARRL's
Petition for Rulemaking remains open at this time, the Commission
expects the Commission may address any necessary power adjustments for
the new 15 kilohertz international allocation in that proceeding. The
Commission also allows continued amateur access to the four discrete
channels at 5332, 5348, 5373, and 5405 kHz at the prevailing 100 W ERP,
which was supported by the majority of commenters and which has not
posed any interference issues. Further, the Commission does not
stipulate power levels based on scenario (emergency/non-emergency), as
this would add unnecessary regulatory complexity. The Commission also
continues to use ERP as the measuring standard--as most amateurs are
familiar with this standard--and the Commission does not adopt antenna
limitations, as the Commission believe that a radiated power limit
would ensure that excess power is not used.

Amateur Service in the 420-450 MHz Band

The Commission's next proposal, based on a request from the NTIA,
was to update the coordination and contact information in footnote
US270 for the areas where 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 this footnote in section
97.313(f) of the rules.
The Commission received no comment on this proposal and implement
the NTIA recommendation, which will clarify compliance with its rules,
by updating footnote US270 and revising the cross reference to this
footnote in section 97.313(f) of the rules.

Deletion of the Broadcasting Service From the 700 MHz Band

The Commission adopts its proposal to delete the broadcasting
service allocations in the 698-758 MHz, 775-788 MHz, and 805-806 MHz
bands from the non-Federal Table and to revise footnote NG159 by
removing the reference to part 74, subpart G. Comments received on this
topic support the Commission's proposal to delete the broadcasting
service allocations. These actions are appropriate given that the
transition of television broadcasting from the 698-806 MHz (700 MHz)
band concluded in 2010 and the remaining primary fixed and mobile
service allocations in the bands effectively gives the licensees in
those bands the flexibility to provide broadcasting services. The
Commission also asked whether it should modify the part 27 service
rules to reflect the deletion of the broadcasting service allocation in
the 700 MHz band. Commenters, while expressing general support, did not
specifically indicate which rules should be modified. The Commission
concludes that modifications to its part 27 rules to reflect the
deletion of the broadcasting service allocation in the 700 MHz band are
unnecessary to reflect the changes made in this Order.

Deletion of Footnote NG155

The Commission's final proposal in the Terrestrial component of the
WRC-15 Notice, concerned the removal of footnote NG155 from the 157.45-
161.575 MHz band in the U.S. Table in section 2.106(a) and from section
2.106(d)(155) of the rules because the frequencies and frequency bands
to which it applies are not currently authorized in part 80 of the
Commission's rules. As the International Table of Frequency Allocations
has already identified frequencies for worldwide intership
communications, the Commission concludes that there is no need to
specify any other frequencies for intership use. For these reasons, and
the lack of any comment on the proposal, the Commission removes
footnote NG155 from section 2.106 of the rules.

Other Matters

The WRC-15 Final Acts also added a provision in Article 4 of the
Radio Regulations (No. 4.24) to describe the use of space research
service (deep space) allocations. Accordingly, in the WRC-15 Notice,
the Commission proposed to add a new paragraph to section 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.''
Commenters within the wireless industry voice concern that adding
this language to section 2.102 of the Commission's rules would affect
spectrum bands (Table 3 below) targeted for future wireless use by both
the Commission and the NTIA's National Spectrum Strategy. CTIA and T-
Mobile

[[Page 1414]]

both comment that multiple frequency bands which an updated section
2.102 would affect, such as the 2110-2120 MHz band, the 7145-7190 MHz
band, the 8400-8500 MHz band, and the 12.7-13.25 GHz band, have already
been allocated for wireless services 2110-2120 MHz, for example, has
been allocated for advanced wireless service (AWS) use) or are being
targeted for future wireless use. Both T-Mobile and Verizon ask the
Commission to fully consider how the expansion of the space research
(deep space) allocation would impact broader agency and U.S.
priorities, including the need for additional terrestrial wireless
capacity. At the same time, T-Mobile does concede that an evaluation of
this allocation is particularly important, as the proposed near-earth
operations include mission critical launch and return to earth
functions.

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

Given shifting spectrum priorities since the completion of the WRC-
15 Final Acts, along with a record reflecting majority opposition to
the proposals outlined in the WRC-15 Notice, the Commission will not
adopt the proposed expansion of the space research (deep space)
allocation.
The Commission next sought comment on a proposal to amend section
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 received no comment on these
proposals and adopt 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 corrects a typographical error in the
definition of ``radiosonde'' in section 2.1(c) (i.e., ``ballon'' should
be balloon).
The Commission next sought comment on a proposal to amend section
2.105(d) of the rules by stating that the footnote references which
appear in the U.S. table below the name(s) of 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 the allocated service are
applicable to only that particular service. The Commission received no
comment on this clarifying proposal and amend section 2.105(d)
accordingly.
Finally, in the WRC-15 Notice, the NTIA recommended that the
Commission add a subset of international footnotes that identify
specific spectrum bands for International Mobile Telecommunications
(IMT) to the non-Federal table. No comments were received on this
subject. The Commission does not generally specify the technology that
licensees must use in a particular frequency band. Identifying
particular bands for IMT use in the non-Federal table would contradict
this general policy. NTIA's recommended subset of international
footnotes identifies specific frequency bands for IMT use but does not
preclude use of the bands for other purposes or establish any priority
for IMT use of the bands. Because the footnotes are merely advisory,
their absence from the non-Federal table will not impact the use of
these bands.

* * * * *
(f) An Earth station or telecommand station may transmit on the
435-438 MHz segment with a maximum of 611 W effective radiated power (1
kW equivalent isotropically radiated power). 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]. No other station may transmit with a transmitter
power exceeding 50 W PEP on the UHF 70 cm band from an area specified
in Sec. 2.106(c)(270)(i) of this chapter, unless expressly 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.
* * * * *
(i) 60 m band power requirements: No station may transmit on the
frequencies 5.332, 5.348, 5.373, and 5.405 MHz in the 60 m band with a
radiated power exceeding 100 W ERP. No station may transmit in the
5.3515-5.3665 MHz band with a radiated power exceeding 9.15 W ERP. For
the purpose of computing ERP, the transmitter PEP will be multiplied by
the antenna gain relative to a half-wave dipole antenna. A half-wave
dipole antenna will be presumed to have a gain of 1 (0 dBd). Licensees
using other antennas must maintain in their station records either the
antenna manufacturer's data on the antenna gain or calculations of the
antenna gain.

(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 above conditions in
this paragraph (r) 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.
