## Introduction

In this document the United States makes proposals for many of the items
on the WRC-07 Agenda. The United States hopes that its proposals will
serve to facilitate the development of consensus on these important
issues. The United States looks forward to working with the ITU
membership to reach a mutual understanding of these important issues
that hold the potential for bringing benefits to governments, industries
and consumers around the globe.

The United States plans to supplement this document with some additional
proposals, including some related to future conferences, at a later
date. The United States also notes its support for many of the
Inter-American Proposals developed within the Inter-American
Telecommunications Commission (CITEL). The United States will consider
adoption of additional Inter-American proposals as they are developed.

## Agenda item 1.2

1.2 to consider allocations and regulatory issues related to the Earth
exploration-satellite (passive) service, space research (passive)
service and the meteorological-satellite service in accordance with
Resolutions **746** **(WRC‑03)** and **742** **(WRC‑03)**

### Proposal for Agenda item 2, Resolution 746

Background information

This proposal addresses *resolves 1* of Resolution 746 (WRC‑03), "to
invite ITU‑R to conduct sharing analyses between geostationary
meteorological satellites operating in the space-to-Earth direction and
the fixed, fixed-satellites and mobile services in the band
18.0‑18.4 GHz to define appropriate sharing criteria with a view to
extending the current 18.1-18.3 GHz geostationary meteorological
satellite allocation in the space-to-Earth direction to 300 MHz of
contiguous spectrum". Presently the meteorological-satellite (MetSat)
service (space-to-Earth), limited to the geostationary-satellite orbit
(GSO), is allocated by footnote 5.519 in the band 18.1-18.3 GHz. The
band is allocated on a primary basis to the fixed-satellite service
(FSS), the fixed service and the mobile service in all three Regions and
these allocations also exist for these same services in the band
17.8-18.1 GHz in all Regions. In both bands, the FSS is allocated in
both the space-to-Earth and Earth-to-space directions. Additionally, in
the 18.1-18.4 GHz band, the FSS (space-to-Earth) allocation has
associated with it Nos. 5.484A and 5.516B. The first provision applies
to non-geostationary FSS satellite systems. The latter provision states
that the band 18.3‑19.3 GHz has been identified for use by high-density
applications in the FSS in Region 2.

WP 7B has been the lead ITU‑R group concerned with analysing the sharing
potential with other services in the band and it has exchanged several
liaison statements with WP 4A. As a consequence of the information
provided by WP 4A, those involved in the design of the next-generation
GSO meteorological satellites have optimized the design to maximize the
level of homogeneity between FSS and MetSat systems. It is envisioned
that this would maximize compatibility and facilitate coordination under
No. 9.7 for operation of both types of systems in the space-to-Earth
direction.

In accordance with No. 5.516 the band 18.0-18.1 GHz in the
Earth-to-space direction is used for feeder links for the
broadcasting-satellite service. Compatibility studies have been
performed to estimate the typical required separation distances in
reverse-band sharing situations between receiving MetSat earth stations
and transmitting BSS feeder uplink stations. In the worst case, it has
been determined that around 40 km separation is required. Therefore, it
is expected that with some care in situating the limited number of
MetSat receiving stations international coordination would rarely be
required under No. 9.17A.

While the expected design of the GSO MetSat satellite networks
envisioned for operation in the 300 MHz wideband appears to be generally
compatible with FSS systems being implemented, it would appear that, for
Region 2, operating MetSat systems below 18.3 GHz would avoid several
potential difficulties. Given the desire to have a common MetSat
allocation in all three Regions, it is proposed to expand the additional
allocation in No. 5.519 from 18.1-18.3 GHz to 18.0-18.3 GHz, including
the limitation to geostationary satellites and the requirement to meet
the provisions of Article 21, Table 21-4.

In addition, ITU‑R studies have shown that, in conjunction with
extending the MetSat allocation, extending the existing FSS coordination
arc principle in this band to the case of MetSat systems coordinating
with FSS networks has the potential to reduce the workload of the Bureau
in identifying affected administrations and fulfils the purposes
envisioned by Resolution 901 (WRC‑03). As such, a consequential
modification to Table 5-1 of Appendix 5 to include this change is also
proposed. It is noted that as with the current No. 9.7, an
administration may request, pursuant to No. 9.41, to be included in
requests for coordination involving the MetSat or FSS service in this
band, indicating the networks for which the value of *T*/*T* calculated
by the method in § 2.2.1.2 and 3.2 of Appendix 8 exceeds 6%.

*NOTE: The changes in portions of Article 5 shown under this proposal
are in addition to those changes shown to the same portion of Article 5
under other United States proposals.*

**Reasons:** Consequential to MOD Nos. 5.519 and 5.519A.

**MOD** USA/5/2

**5.519** *Additional allocation:  *the band 18.0-18.3 GHz is also
allocated to the meteorological-satellite service (space-to-Earth) on a
primary basis. Its use is limited to geostationary satellites and shall
be in accordance with the provisions of Article **21**, Table **21‑4**.

**Reasons:** Expanding the current 18.1-18.3 GHz geostationary
meteorological-satellite service (space-to-Earth) allocation to the band
18.0-18.1 GHz by modifying No. 5.519 will provide greater flexibility
for the meteorological-satellite service and extend the current criteria
(i.e. the limitation to geostationary satellites and the requirement to
meet the provisions of Article 21, Table 21-4) to protect existing
services.

**ADD** USA/5/3

**5.519A** In the band 18.0-18.1 GHz, earth stations of the
meteorological-satellite service (space‑to-Earth) in Region 1 and 3
shall not claim protection from the broadcasting-satellite service
feeder-link earth stations operating under Appendix **30A**, nor put any
limitations or restrictions on the locations of the
broadcasting-satellite service feeder-link earth stations anywhere
within the service area of the feeder link.

**Reasons:** Analysis has shown that under worst-case assumptions a
maximum separation distance of 40 km would be required between a MetSat
receiving station and a BSS feeder-link transmitting station in order to
protect the MetSat receiving station. This minimal separation distance
should ensure that both MetSat receiving stations and BSS feeder links
can effectively use this band. Nevertheless, this provision would ensure
that MetSat receiving stations could not affect the Appendix 30A Plan.

## Agenda item 1.3

1.3 in accordance with Resolution **747 (WRC‑03)**, consider upgrading
the radiolocation service to primary allocation status in the bands
9 000-9 200 MHz and 9 300-9 500 MHz and extending by up to 200 MHz the
existing primary allocations to the Earth exploration-satellite service
(EESS) (active) and the space research service (SRS) (active) in the
band 9 500-9 800 MHz without placing undue constraint on the services to
which the bands are allocated

### Proposal for Agenda item 1.3, 200 MHz extension of the primary EESS (active) and SRS (active) allocations in the 9 500-9 800 MHz band

Background information

The band 9 500-9 800 MHz is allocated on a primary basis to the Earth
exploration-satellite (EESS) (active), space research (SRS) (active),
radiolocation and radionavigation services. In order to satisfy
requirements for increased resolution of global environmental and land
use monitoring and terrain mapping of planetary surfaces, EESS (active)
and the SRS (active) allocations require an increase of 200 MHz.

ITU‑R studied the compatibility between EESS (active) and the existing
services in the two bands identified by Resolution 747 (WRC-03) for
consideration as extension bands.

Results of ITU‑R tests and measurements indicate that representative
radiolocation and radionavigation radars do not suffer any performance
degradation due to any of the representative EESS (active) waveforms.
Results of various ITU‑R compatibility studies combined with these test
and measurements indicate that sharing is feasible in the additional 200
MHz of spectrum between the EESS (active) and existing services in
either the 9 300-9 500 MHz band or the 9 800-10 000 MHz band. Since the
SRS (active) systems operate in the vicinity of planets and celestial
bodies other than the Earth, these systems need not show compatibility
with Earth-based systems.

The proposal provides for an extension of 200 MHz to the EESS (active)
and SRS (active). It extends the protection given in RR No. 5.476A to
the radiolocation and radionavigation services in the existing
9 500-9 800 MHz band to this extension. Given that the extension is only
required for wideband systems that could not operate within the existing
allocation, the proposal restricts the use of the extension band to
wideband systems.

### Proposal for Agenda item 1.3, upgrade of radiolocation service in the band 9 000-9 200 MHz and 9 300-9 500 MHz

Background information

The proposal addresses the upgrade of the radiolocation service in the
band 9 000-9 200 MHz and 9 300-9 500 MHz. As identified in Resolution
747 (WRC-03), there is a need to provide contiguous primary spectrum
around the 9 GHz band in order for existing and planned radiolocation
systems to satisfy their required missions. Changes in technology and
emerging requirements for increased image resolution and increased range
accuracy necessitate wider contiguous emission bandwidths. Therefore,
there is a need to upgrade the status of frequency allocations to the
radiolocation service in the frequency range 9 000-9 200 MHz and
9 300-9 500 MHz.

The bands 9 000-9 200 MHz and 9 300-9 500 MHz are allocated on a primary
basis to aeronautical radionavigation and radionavigation, respectively.
Radio Regulation No. 4.10 recognizes radionavigation as a safety
service. The radiolocation services and the radionavigation service have
demonstrated compatible operations over many years through the use of
similar system characteristics such as low-duty cycle emissions,
scanning beams and interference reduction techniques. For example, past
operational experience in the 2 900-3 100 MHz band as found in Report
ITU‑R M.2032 -- Tests illustrating the compatibility between maritime
radionavigation radars and emissions from radiolocation radars in the
band 2 900-3 100 MHz, confirms that it is possible to mitigate
interference from radiolocation radars to maritime radionavigation
radars in the band.

Some studies have been completed within ITU‑R WP 8B that characterize
the technical performance and protection criteria of radiolocation and
radionavigation systems that ensure compatible operations in the bands
9 000-9 200 MHz and 9 300-9 500 MHz. Recommendation ITU‑R M.1313
contains the technical characteristics and protection criteria for
maritime radars in the band 9 300-9 500 MHz and that Recommendation
ITU‑R M.1372 identifies interference reduction techniques which enhance
compatibility among radar systems.

ITU‑R studies that have been completed so far, such as on maritime
radionavigation radars and emissions from radiolocation radars in the
band 9 200‑9 500 MHz illustrate compatibility between the two services
in this band and are an indicator of how the sharing would be with other
radionavigation systems. These studies indicate that typical maritime
radionavigation radars can suppress emissions from other radars, even
when the maritime radars receive interference with very high
interference-to-noise (*I*/*N*) ratios if the unwanted pulsed waveform
is asynchronous and has a low effective duty cycle. These study results
support the successful historical sharing experience

between the two services in the 9 200-9 500 MHz band. As most maritime
radars in the 9 000-9 500 MHz bands are very similar in design and
operation, one does not expect a great variation from the protection
criteria that was derived from the radars that were used for these
studies. Therefore, there is an indication that the results could apply
to other similar radars that operate in the 9 000-9 500 MHz bands as
well. Therefore a primary allocation for radiolocation can be added to
the 9 000-9 200 and 9 300-9 500 MHz bands.

## Agenda item 1.5

1.5 to consider spectrum requirements and possible additional spectrum
allocations for aeronautical telecommand and high bit-rate aeronautical
telemetry, in accordance with Resolution **230 (WRC‑03)**

Background information

This Agenda item addresses a growing demand for spectrum that is
allocated for aeronautical telemetry and associated telecommand. There
is a large and growing shortfall in spectrum that is necessary to
conduct aeronautical telemetry. The shortfall is exacerbated by the loss
of telemetry spectrum diverted to other than telemetry applications. As
indicated in the responses to Question ITU‑R 231/8, additional spectrum
is necessary due to rapidly increasing data rates associated with the
testing of new and emerging technologies. For example, newer
technologies rely increasingly on high-resolution video for monitoring
aircraft functions or increased use of computer-based aircraft systems.
Without access to additional spectrum, aeronautical development would be
subject to escalating delays and costs, and the growth of aerospace
industry would be impaired (including equipment manufacturers, civilian
programmes and test ranges, and airlines). New worldwide telemetry
spectrum will aid numerous countries and the international aeronautical
community, as administrations continue to support their national
airlines and some administrations initiate their own test programmes.
Existing international allocations used for aeronautical telemetry will
need to remain available.

Aeronautical mobile telemetry (AMT) is an application within the mobile
service. Depending on the extent to which new AMT spectrum requirements
can be fulfilled using primary mobile service allocations, it is
important that the suitability of additional spectrum for AMT be
studied. International recognition of bands suitable for AMT will not
only encourage international harmonization of test equipment, but also
provide assurance to administrations that, based on technical studies
conducted in ITU‑R, implementation of telemetry systems can be
accomplished by those administrations wishing to do so without
disrupting other services using the bands. This will also enable
manufacturers to offer prospective customers aircraft with common test
equipment packages, and thus help airlines achieve additional economies
in the aircraft life-cycle cost. Moreover, by establishing conditions
under which AMT use of a band would be suitable, incumbent users of the
spectrum can be assured that they will not experience unacceptable
interference, and manufacturers and test ranges will have a measure of
additional certainty for the substantial investment in range
infrastructure that will be incurred in equipping to use new bands
deemed suitable for AMT.

The need for additional spectrum has been studied by several
administrations who indicate that as much as an additional 650 MHz may
be required for aeronautical flight test telemetry. The requirement may
differ depending on national and regional needs. It is not necessary to
fulfil all AMT requirements in only one band. The new requirements for
aeronautical telemetry are only in the air-to-ground direction inasmuch
as telecommand functions (i.e. ground-to-air transmissions) can be
accommodated in existing bands. In addition, this new AMT spectrum will
not be used for the protection of life and property. The latter AMT
applications will continue to be accommodated in existing bands (see
Nos. 5.342, 5.343, and 5.394 in the Radio Regulations). Hence,
aeronautical mobile telemetry applications in the new spectrum will not
require the level of protection associated with operations in existing
telemetry bands. However, the AMT application will be moving into bands,
such as the 6 GHz band, that are used for critical applications such as
public safety communications (including police and fire vehicle
dispatch), coordinating the movement of railroad trains, controlling
natural gas and oil pipelines, regulating the electric grid, and
backhauling wireless telephone traffic.

ITU‑R WP 8B conducted numerous studies of bands that could be used to
satisfy the requirements of aeronautical telemetry applications.
Available technologies, signal fading considerations, and the scope of
Agenda item 1.5 dictate that the new wideband AMT spectrum requirements
be fulfilled in the 3 GHz to 7 GHz frequency range. With the cooperation
of other responsible WPs, several bands were studied for suitability to
implement AMT given the other co-primary services in the band. These are
the 4 400-4 940, 5 925-6 700, and 5 091-5 150 MHz bands. Portions of
these bands, such as the 5 925-6 700 MHz band, are used for public
safety communications and other applications that require a high degree
of protection. It is expected that the implementation of telemetry may
require avoiding co-frequency operations with local services in some of
the bands. This will likely mean that the spectrum requirement for AMT
would be satisfied using portions of each of the bands studied and
deemed suitable for AMT implementation. Suitable means, in this context,
that AMT can be implemented compatibly with other co-primary services
utilizing the band, assuming the implementation is in accordance with
the established sharing criteria.

ITU‑R studies have determined conditions under which aeronautical mobile
telemetry for flight test purposes can be implemented in these bands
without adversely affecting the operation of existing systems and
allocated services. The ability to implement AMT in some areas and in
some portions of the bands may be restricted based on deployment density
of other co-primary service stations, such as the fixed service (FS)
stations, in the same vicinity. In cases where AMT operations could
impact radio astronomy observatories, it may be possible to arrange AMT
time-sharing with those observatories to enable AMT use of the
4 825-4 835 MHz band.

In the past, terms such as "designated" or "identified" have been used
in the Radio Regulations with respect to certain technologies and bands
to encourage technology implementation on a worldwide basis without
making the use by administrations mandatory and without establishing any
priority of use. Since the spectrum requirements and the conditions
under which AMT will be implemented can vary by administration, an
approach is proposed to simply indicate the suitability of certain bands
for the implementation of AMT based on compatibility studies. This
approach provides valuable information while maximizing the flexibility
of implementing AMT. A finding that spectrum is suitable for AMT
implementation inherently would not establish any priority of use or
preclude use of the bands by other co-primary services.

Any authorization of AMT operations within these bands would be decided
by individual administrations, and would be specifically limited to
testing of aircraft at designated flight test areas in the air-to-ground
direction within those individual countries. According to No. 5.444 of
the Radio Regulations, the 5 091-5 150 MHz band is to be used by the MLS
(microwave landing system) with precedence given to this international
standard system. However, the band 5 091-5 150 MHz is not yet in use by
MLS.

The 5 091-5 150 MHz band is already allocated to the aeronautical
radionavigation service (ARNS) on a primary basis in all Regions and is
also allocated to the fixed-satellite service (FSS) (Earth-to-space) on
a primary basis. This FSS allocation is limited to feeder links of
non‑geostationary mobile-satellite systems in the mobile-satellite
service and is subject to coordination under No. 9.11A. Test aircraft
are not intended to use ground-to-air transmissions in this ARNS band.
Administrations are also considering the band 5 091-5 150 MHz under
Agenda item 1.6 for allocation to the aeronautical mobile (R) service.
Studies have shown that AMT can share with both the FSS and the possible
AM(R)S system in the band 5 091-5 150 MHz.

Use of the 4 400-4 940 MHz, 5 925-6 700 MHz, and 5 091-5 150 MHz bands
for aeronautical telemetry is subject to coordination with FSS earth
stations in accordance with Article 9 of the ITU Radio Regulations.

ITU‑R studies have not adequately demonstrated that aeronautical
telemetry or telecommand applications could share spectrum with other
uses in the band 5 150-5 250 MHz.

During the meeting of ITU‑R Working Party 8B held in September 2004, one
administration presented a paper (Document 8B/30) which proposed the
adoption of definitions for the terms "aeronautical telemetry," and
"aeronautical telecommand". WP 8B square-bracketed the definitions in
the CPM text and agreed to carry the matter forward for resolution at
the next meeting. See the Chairman's Report of the 15th meeting of
Working Party 8B, Document 8B/98, Annex 6.

The United States believes definitions in Article 1 of aeronautical
telemetry and aeronautical telecommand are unnecessary. Aeronautical
mobile telemetry (AMT) has been treated successfully in ITU. The effort
to agree Article 1 definitions would complicate the work of the WRC. The
United States also believes that a less formal approach to exploring the
meaning of these terms is more appropriate than adopting formal
definitions under Article 1 of the Radio Regulations. To the extent any
administration should be of the view that further clarification
regarding the scope of this Agenda item is needed, it would be in order
that such clarification be provided via modifications to the WP 8B
preliminary draft new Report.

Remotely piloted aircraft, also referred to as unmanned aerial vehicles
(UAVs), are envisioned by many as fulfilling a variety of civil
applications, and flying in national airspace of numerous
administrations within the next decade. Vehicles such as these must be
carefully tested before any such operation commences given the obvious
safety implications associated with these flights.

Additional spectrum designated for aeronautical mobile telemetry
pursuant to Agenda item 1.5 may be utilized for the flight testing of
such aircraft. Such testing is expected to occur at designated test
centres on a coordinated basis with incumbent services. Such use does
not include command and control of UAVs in national airspace.
Consideration of the spectrum needs of UAVs operating in national
airspace could be the subject of other Agenda items.

ARTICLE 1

Terms and definitions

With regard to definitions for Aeronautical Telemetry and Aeronautical
Telecommand Pursuant to Agenda item 1.5 (WRC-03), the United States
proposes no change.

**Reasons:** Formal definitions are not necessary for resolution of this
Agenda item. Aeronautical mobile telemetry (AMT) has been conducted for
many years internationally without special definitions for the terms
"aeronautical telemetry" or "aeronautical telecommand". See No. 5.342,
No. 5.343, No. 5.394 and No. 5.395.

**[NOC]{.underline}** USA/5/12

The operational command and control requirements of remotely piloted
aircraft unmanned aerial vehicles, (UAVs) should not be considered under
Agenda item 1.5.

**Reasons:** Agenda item 1.5 was approved for one purpose only; namely,
to ensure adequate spectrum resources for flight testing in the face of
extraordinary increase in telemetry data rates. Accordingly, Agenda item
1.5 is not appropriate for consideration of UAVs operating in airspace
under civil control.

*NOTE: The changes in portions of Article 5 shown under this proposal
are in addition to those changes shown to the same portion of Article 5
under other United States proposals.*

**Reasons:** The aeronautical telecommand and high bit-rate aeronautical
telemetry is not compatible with the existing services allocated in band
5 150-5 250 MHz.

**ADD** USA/5/17

**5.441A** The bands 4 400-4 940 MHz and 5 925-6 700 MHz are suitable
for the implementation of aeronautical mobile telemetry applications for
flight testing by aircraft stations. The provisions of No. **1.83**
apply. Any such use does not preclude the use of these bands by other
mobile service applications or by other services to which these bands
are allocated on a co-primary basis and does not establish priority in
the Radio Regulations. Resolution **\[AMT4-6 GHz\]** shall apply.

**Reasons:** A footnote as above could be used to satisfy a portion of
the 650 MHz spectrum requirement. The advantage of such a footnote is
that it merely states that the bands are suitable and that, via the
provisions of Resolution \[AMT4-6 GHz\], AMT for flight testing could
share spectrum while not precluding the use of the bands by other
co-primary services.

**ADD** USA/5/18

**5.444C** The band 5 091-5 150 MHz is also allocated to the
aeronautical mobile service, limited to flight test telemetry
transmissions by aircraft stations. The provisions of No. **1.83**
apply. Any such use does not preclude the use of this band by other
services to which this band is allocated on a co-primary basis and does
not establish priority in the Radio Regulations. Resolution
**\[AMT‑5 GHz\]** shall apply.

**Reasons:** This allocation is necessary for implementation of AMT in
the band 5 091-5 150 MHz. The footnote will ensure that the allocation
to AMS is limited to air-to-ground flight test telemetry only, while not
precluding the use of the bands by other co-primary services. Resolution

mobile service are limited to aeronautical mobile telemetry for flight
testing in the air-to-ground direction. Resolution **\[AMT4-6 GHz\]**
shall apply.

**Reasons:** This modification to RR No. 5.442 exempts AMT from the
aeronautical mobile exclusion.

considering

*a)* that studies have been conducted within ITU‑R concerning the
sharing and compatibility of aeronautical mobile telemetry for flight
testing with other services in the bands 4 400-4 940 and 5 925-6 700
MHz;

*b)* that the bands 4 400-4 940 MHz and 5 925-6 700 MHz are suitable for
the implementation of aeronautical mobile telemetry applications for
flight test purposes, when the criteria in *resolves* 2 are used;

*c)* that spectrum efficiency is enhanced in situations where new

occupied,

recognizing

the fixed and mobile services on a primary basis;

*b)* that the band 4 500-4 800 MHz is allocated to the fixed,
fixed-satellite (space-to-Earth), and mobile services on a co-primary
basis;

*c)* that the band 4 825-4 835 MHz is allocated to the radio astronomy
service on a primary basis in Argentina, Australia and Canada (see
No. **5.443**), and that the band 4 800-4 990 MHz is allocated to the

applies;

*d)* that No. **5.442** (MOD) applies to aeronautical mobile telemetry
for flight testing operations in the band 4 825-4 835 MHz;

fixed-satellite (Earth-to-space), and mobile services on a co-primary
basis;

*f)* that the use of the band 4 500-4 800 MHz (space-to-Earth) by the
fixed-satellite service shall be in accordance with the provisions of
Appendix **30B** **(**see No. **5.441)**;

*g)* that provisions for the coordination of terrestrial and space
services exist in the Radio Regulations,

noting

that the criteria used and assumptions made in sharing studies between
aeronautical mobile telemetry flight test applications and other

resolves

1 that administrations take into account that the bands 4 400-4 940 MHz
and 5 925-6 700 MHz are suitable for the implementation of aeronautical
mobile telemetry applications for flight testing;

2 that administrations implementing aeronautical mobile telemetry for
flight test purposes, shall utilize the criteria set forth below:

-- transmissions limited to those from aircraft stations only, see
No. **1.83**;

-- the peak e.i.r.p. shall not exceed --2.2 dB(W/MHz);

-- limit transmissions to designated flight test areas, where flight
test areas are airspace designated by administrations for flight testing
within their territories;

-- if operation of AMT aircraft stations are planned within 500 km of
the territory of an administration in which the band 4 825-4 835 MHz is
allocated to radio astronomy on a primary basis (see No. **5.443**),
consult with that administration to determine whether any special
measures are needed to prevent interference to their radio astronomy
observations;

-- in the bands 4 400-4 940 MHz and 5 925-6 700 MHz, bilateral
coordination for transmitting AMT aircraft station with respect to
receiving fixed or mobile stations must be effected if the AMT aircraft
station will operate within 450 km of the receiving fixed or mobile
stations of another administration. The following procedure should be
used to establish whether fixed or mobile service receiver within 450 km
of the flight test area will receive an acceptable level of
interference:

-- determine if the receiving fixed or mobile station's antenna main
beam axis, out to a distance of 450 km from the fixed service receiver,
passes within 12 km of the designated area used by transmitting AMT
aircraft stations, where this distance is measured orthogonally from the
main beam axis projection on the Earth's surface to the nearest boundary
of the projection of the flight test area on the Earth's surface;

-- if the main beam axis does not intersect the flight test area or any
point within the 12 km offset, the interference could be accepted.
Otherwise further bilateral coordination discussions would be needed.

**Reasons:** A resolution to indicate the conditions under which AMT
will operate.

## Agenda item 1.6

1.6 to consider additional allocations for the aeronautical mobile (R)
service in parts of the bands between 108 MHz and 6 GHz, in accordance
with Resolution **414** **(WRC‑03)** and, to study current satellite
frequency allocations, that will support the modernization of civil
aviation telecommunication systems, taking into account Resolution
**415** **(WRC‑03)**

### Proposal for Agenda item 1.6, Resolution 414

Background information

This proposal considers additional allocations for the aeronautical
mobile (R) service (AM(R)S) in parts of the bands between 108 MHz and
6 GHz, in accordance with Resolution 414 (WRC‑03).

Existing AM(R)S bands are nearing saturation in high traffic areas. In
addition, new applications and concepts in air traffic management put
further pressure on existing AM(R)S bands. Resolution 414** **(WRC-03)
states that new technologies to support air navigation may not conform
to the definition of aeronautical radionavigation in the Radio
Regulations. WRC‑03 provided a mechanism to implement these new aviation
technologies by adding AM(R)S use in the band 108-117.975 MHz by
footnote 5.197A in accordance with Resolution 413 (WRC-03)[^1]. One
emerging application driving requirements for new AM(R)S spectrum is the
integration of command and control for unmanned aircraft (UA) into air
traffic services (ATS) airspace. Conversely, AM(R)S spectrum is not
appropriate for UA payload data use, such as downlinking information and
operational data from the UA.

ITU‑R Working Party 8B and the International Civil Aviation Organization
(ICAO) developed a draft operational concept, and technology selection
criteria and procedures for new aviation technology. WP 8B and ICAO
determined that the new aviation systems require two distinct categories
of AM(R)S spectrum. The first category for surface applications could
support high data throughput over moderate transmission distances. There
is a high degree of reuse of this spectrum. For surface applications,
ICAO and WP 8B recommended 5 091-5 150 MHz as a suitable band. ITU‑R has
studied the band 5 091-5 150 MHz under Agenda item 1.5 for the purpose
of aeronautical mobile telemetry applications. These studies have shown
that AM(R)S can share with both the existing fixed-satellite service and
possible aeronautical telemetry (AMT) systems in the band 5 091-5 150
MHz.

The second category for bidirectional air-to-ground applications could
support a moderate data throughput over longer propagation distances out
to radio line-of-sight. These applications require a number of distinct
channels to allow for sector-to-sector assignments. For radio
line-of-sight applications, ICAO and WP 8B recommended 960-1 024 MHz as
a suitable band. The provisions of the new footnote No. 5.328C and
Resolution AM(R)S contained in this proposal should enter into force on
17 November 2007. The provisional application of this footnote and
associated resolution should be contained in a WRC resolution similar to
Resolution 96** **(WRC-03) on the provisional application of certain
provisions of the Radio Regulations as revised by WRC-03 and abrogation
of certain resolutions and recommendations.

The 5 091-5 150 MHz band is used by the fixed-satellite service to
provide feeder uplinks for non-geostationary mobile-satellite service
systems. Studies within WP 8B have shown that those feeder links would
be protected from interference from new AM(R)S applications proposed for
this band. No priority over other uses in this band is established for
the AM(R)S uses.

*b)* that Annex 10 of the Convention of the International Civil Aviation
Organization (ICAO) contains standards and recommended practices (SARPs)
for aeronautical radionavigation and radiocommunication systems used by
international civil aviation;

*c)* that all compatibility issues between the ICAO standard Universal
Access Transceiver (UAT) and other systems which operate in the band
960-1 024 MHz have been addressed within ICAO,

noting

that excluding the system identified in *recognizing c)*, no
compatibility criteria currently exist between AM(R)S systems proposed
for operations in the frequency band 960-1 024 MHz and the existing ARNS
aeronautical systems in the band,

resolves

that prior to operating in the frequency band 960-1 024 MHz any AM(R)S
systems shall have Standards and Recommended Practices requirements
published in Annex 10 of the ICAO Convention on International Civil
Aviation, and that those requirements will ensure compatibility with and
not constrain the future development of ARNS systems operating in
accordance with international (ICAO) standards,

instructs the Secretary-General

to bring this Resolution to the attention of the ICAO.

**Reasons:** A resolution is needed to indicate the systems allowed
under the AM(R)S allocation in the 960-1 024 MHz band and to explain the
role of the ICAO in developing standards for compatibility between ARNS
and AM(R)S in this band.

### Proposal for Agenda item 1.6, Resolution 415

Background information

This proposal is concerned with Resolution 415, Study of current
satellite frequency allocations that will support the modernization of
civil aviation telecommunication systems.

With ever-increasing speed, existing and new communication systems are
being based on Internet-related protocols and services. Access to these
services with sufficient bandwidth is becoming essential for all forms
of telecommunications. Communications with aircraft are not exempt from
this growing dependence on Internet applications. Aircraft owners and
operators are realizing that without this access aeronautical operations
will be hindered from gaining the efficiencies and benefits that these
types of service offer. Internet usage is fast becoming dependent on
broadband connectivity. A demonstrated viable means of providing this
connectivity for mobile platforms on an intercontinental basis is
through satellite channels.

The availability of this broadband communications capability on board
aircraft will promote the efficiency of aircraft operations and provide
access to information, such as enhanced weather data, hitherto
inaccessible to aircraft in flight.

ITU‑R recognized that the use of the 14.0-14.5 GHz band for aeronautical
mobile-satellite service (AMSS) on a secondary basis was compatible with
current fixed-satellite service (FSS) systems and was supported by
studies leading up to WRC-03. Additional studies in ITU‑R also confirmed
compatibility with other services in the 14.0-14.5 GHz range. At WRC-03,
the decision was made to expand the secondary MSS allocation in the
14-14.5 GHz band to include AMSS (Earth-to-space). This decision has
enabled the use of Internet applications by aircrews and passengers.

Related to this decision, there were discussions of a downlink that
could be used with this new uplink allocation and it was concluded at
the 14th plenary meeting that:

1\) The downlink (space-to-Earth) bands associated with the secondary
mobile-satellite service allocation shall be: in Region 1, 10.7-11.7 GHz
and 12.5-12.75 GHz; in Region 2, 10.7-12.2 GHz and 12.7-12.75 GHz; and
in Region 3, 10.7-11.7 GHz and 12.2-12.75 GHz.

2\) The use of the downlink (space-to-Earth) bands listed above by the
aeronautical mobile-satellite service shall be under the provisions of
No. 4.4.

While a corresponding downlink allocation in the 11/12 GHz bands would
address the lack of an AMSS downlink in the Table of Frequency
Allocations, many administrations have voiced opinions that such a new
allocation is not covered under Agenda item 1.6, Resolution 415. Because
of these strong views, no allocation is proposed.

ARTICLE 5

Frequency allocations

The United States proposes no change to any frequency allocation between
10.7‑12.75 GHz.

**Reasons:** No changes to Article 5 are needed under this Agenda item.

**[NOC]{.underline}** USA/5/31

**5.504A** In the band 14-14.5 GHz, aircraft earth stations in the
secondary aeronautical mobile-satellite service may also communicate
with space stations in the fixed-satellite service. The provisions of
Nos. **5.29**, **5.30** and **5.31** apply.     (WRC-03)

**Reasons:** Under Agenda item 1.11 at WRC-03, the secondary allocation
at 14-14.5 GHz to the mobile-satellite service (MSS) was extended to
include the aeronautical mobile-satellite service (AMSS). The
corresponding AMSS downlink bands at 12 GHz are used under the
provisions of RR No. 4.4. While a corresponding new downlink allocation
in the 11/12 GHz bands would address the lack of an AMSS downlink in the
Table of Frequency Allocations, such a new allocation, in the view of
many administrations, is not covered under Agenda item 1.6.

## Agenda item 1.7

1.7 to consider the results of ITU‑R studies regarding sharing between
the mobile-satellite service and the SRS (passive) in the band
1 668-1 668.4 MHz, and between the mobile-satellite service and the
mobile service in the band 1 668.4-1 675 MHz in accordance with
Resolution **744 (WRC‑03)**

Background information

**(Issue A)** The band 1 668-1 668.4 MHz is allocated to the space
research (passive) service (SRS (passive)) and the mobile-satellite
service (MSS) (Earth-to-space). The space research allocation may be
used by space-based radio astronomy applications, as part of space very
long baseline interferometry systems (S-VLBI). The band 1 668-1 668.4
MHz is a part of the band, 1 660.5-1 668.4 MHz, allocated to the SRS
(passive). However S-VLBI spaceborne receivers typically receive over a
wider frequency band because a wider band is desirable for increasing
the sensitivity of systems and also to observe highly red-shifted
objects.

The potential for interference from mobile earth stations (MES)
operating in the MSS to the S‑VLBI systems has been studied by ITU‑R, in
accordance with Resolution 744. The studies concluded that to ensure
protection of future SRS (passive) systems operating in highly
elliptical orbits, with an apogee of 150 000 km and higher, the power
density of MESs operating in the GSO MSS networks should not exceed to
--12.5 dB(W/4 kHz) in any part of the frequency band 1 668-1 668.4 MHz.

**(Issue B)** The band 1 668.4-1 675 MHz is allocated to the fixed and
mobile services on a primary basis. WRC-03 allocated to MSS the bands
1 518-1 525 MHz (space-to-Earth) and 1 668.4-1 675 MHz (Earth-to-space).
In allocating the band 1 668.4-1 675 MHz to the MSS, WRC-03 recognized
that this allocation cannot be used in the United States. Specifically,
WRC-03 recognized that constraints on the MSS in the corresponding
downlink band 1 518-1 525 MHz (see

RR 21.16 and 5.348B) preclude the feasibility of using the 1 668-1 675
MHz for MSS uplinks in the United States. WRC-03 further recognized that
the United States intends to implement systems in the existing fixed and
mobile allocation in the 1 668-1 675 MHz and that these systems must not
be constrained by the new MSS allocation. To that end, WRC-03 adopted
Resolution 744 (WRC‑03). In accordance with the *recommends* of
Resolution 744 (WRC-03), the studies conducted under this resolution did
not consider sharing between MSS and mobile services in the United
States.

The United States therefore, proposes to maintain the *resolves* of
Resolution 744 as adopted at WRC-03.

RESOLUTION 744 (Rev.WRC-07)

Sharing between the mobile-satellite service (Earth-to-space) and the
fixed and\
mobile services in the band 1 668.4-1 675 MHz

The World Radiocommunication Conference (Geneva, 2007),

considering

*a)* that WRC-03 made a global allocation to the mobile-satellite
service (MSS) (Earth-to-space) in the band 1 668-1 675 MHz and a global
allocation to the MSS (space-to-Earth) in the band 1 518-1 525 MHz;

*b)* that due to sharing conditions between MSS (space-to-Earth) and the
aeronautical mobile service for telemetry in the band 1 518-1 525 MHz
(see No. **5.348B**), MSS operation in the United States of America is
unlikely to be feasible;

*c)* that the above constraints on the MSS in the band 1 518-1 525 MHz
therefore limit the possible use of the band 1 668-1 675 MHz by the MSS
in the United States of America;

*d)* that the band 1 660.5-1 668.4 MHz is allocated to the space
research (passive) service;

*e)* that the band 1 670-1 675 MHz is used in the United States of
America for the fixed and mobile services,

considering further

that the band 1 668.4-1 675 MHz is allocated to the fixed and mobile
services,

resolves

that, in the band 1 670-1 675 MHz, stations in the MSS shall not claim
protection from fixed and mobile stations operating within the United
States of America.

**Reasons:** The studies called for in Resolution 744 (WRC-03) have been
completed. No further action is required.

## Agenda item 1.8

1.8 to consider the results of ITU‑R studies on technical sharing and
regulatory provisions for the application of high altitude platform
stations operating in the bands 27.5-28.35 GHz and 31‑31.3 GHz in
response to Resolution **145** **(WRC‑03),** and for high altitude
platform stations operating in the bands 47.2-47.5 GHz and 47.9-48.2 GHz
in response to Resolution **122 (Rev.WRC‑03)**

### Proposal for Agenda item 1.8, Resolution 122

Background information

ITU has been considering the implications of HAPS in the fixed service
in the 47.2-47.5 GHz and 47.9-48.2 GHz band since 1997, when WRC-97
first made provision for the operation of HAPS within the fixed service.
Studies have been ongoing under versions of Resolution 122 since WRC‑97.

Resolution 122 (Rev.WRC-2000) indicated that sharing studies remain to
be completed between the fixed-satellite service (FSS) and HAPS
operations in the FS. Pending the completion of studies, Resolution 122
(Rev.WRC-2000) instructed the Radiocommunication Bureau "that from
22 November 1997, and pending review of the sharing studies in
*considering j)* and review of the notification process by WRC-03, the
Bureau shall accept notices in the bands 47.2-47.5 GHz and 47.9-48.2 GHz
only for HAPS in the fixed service and for feeder links for the
broadcasting-satellite service, shall continue to process notices for
FSS networks (except for feeder links for the broadcasting-satellite
service) for which complete information for advance publication has been
received prior to 27 October 1997, and shall inform the notifying
administrations accordingly". In other words, notices received after 22
November, 1997 from non-BSS feeder link FSS networks in the
47.2-47.5 GHz and 47.9-48.2 GHz bands have not been accepted.

Resolution 122 (Rev.WRC-03) extended the restriction on processing of
notices for FSS networks other than those providing service exclusively
within Region 2. It also instructed the Bureau to maintain, until a date
to be decided by a future WRC, notices concerning HAPS that were
received by the Bureau prior to 22 November 1997 and provisionally
recorded in the Master International Frequency Register. This is a
substantial exception to No. 11.26, which provides that "\[n\]otices
relating to assignments for high altitude platform stations in the fixed
service in the bands 47.2-47.5 GHz and 47.9-48.2 GHz shall reach the
Bureau not earlier than five years before the assignments are brought
into use".

The studies regarding HAPS in the 47.2-47.5 GHz and 47.9-48.2 GHz bands
have been completed and the results are contained in Recommendation
ITU‑R SF.1481. This Recommendation makes clear that co-frequency
operations between HAPS in the fixed service and FSS networks and
systems are feasible in the 47.2-47.5 GHz and 47.9-48.2 GHz bands, even
while noting that "there may be a need to develop the maximum allowable
pfd at satellites on the GSO due to aggregate interference caused by
ground user terminals of high-altitude platform networks". The revision
to Resolution 122 that was approved at WRC-03 confirms that co-existence
between HAPS in the FS and the FSS at 47.2-47.5 GHz and 47.9-48.2 GHz is
feasible, as administrations were encouraged to facilitate interservice
coordination.

In the WRC-03 revision of Resolution 122, ITU‑R was invited to study
power limitations on HAPS ground stations to facilitate sharing with
space station receivers, regulatory provisions to address deployment of
HAPS in the FS near country borders, and technical sharing criteria
between HAPS in the FS and both radio astronomy and FSS systems (taking
into account the operational environments and the requirements of FSS
systems). With the exception of interference to and from FSS spacecraft,
and border area coordination matters in the FS, the deployment of HAPS
is a

national issue. The issue of interference between the FSS satellite and
HAPS networks can be addressed through coordination using Articles 9 and
11 of the Radio Regulations. As a result, Resolution 122 can be
suppressed, provided that reference to the use of Article **9** for HAPS
is included in a new resolution that is referenced in No. 5.552A of the
Radio Regulations. The Bureau should be instructed to retain all notices
concerning HAPS that are maintained in the MIFR only by virtue of
instructs the Director of the Radiocommunication Bureau 1 of Resolution
122 (Rev.WRC‑03) only until 1 January 2010, unless the notifying
administration earlier informs the Bureau that the notified assignments
have been brought into use.

completed. The Resolution 122 application of the provisions of Article 9
is proposed for incorporation into the Radio Regulation.

Frequency allocations

**MOD** USA/5/37

**5.552A** The allocation to the fixed service in the bands
47.2-47.5 GHz and 47.9-48.2 GHz is designated for use by high altitude
platform stations. The use of the bands 47.2-47.5 GHz and 47.9-48.2 GHz
by high altitude platforms in the fixed service is subject to the
provisions of Resolution **\[VBANDHAPS\] (WRC-07)**[^2]. All notices for
high altitude platform stations in these bands that were filed with the
Bureau prior to 22 November 1997 shall be cancelled as of 1 January 2010
unless the notifying administration informs the Bureau before this date
that the notified assignments have been brought into use.     (WRC-97)

**Reasons:** Consequential to the suppression of Resolution 122. While
studies have been completed, HAPS systems still need to be subject to
the provisions of Article 9 to ensure coordination with the FSS at
47 GHz. Nos. 9.17 and 9.18, which apply for the coordination of
terrestrial stations, including HAPS, with earth stations, are currently
applicable without having to be called out in a footnote to Article 5 of
the Radio Regulations. Resolution \[VBANDHAPS\] is a new Resolution that
is intended to address the previously unaddressed coordination case of
transmitting HAPS ground-based stations with receiving space station of
the FSS, when the HAPS ground station appears in the coverage area of a
satellite network. The final sentence of the provision is needed because
Resolution 122 (Rev.WRC-03) instructs the BR to maintain HAPS notices
received prior to 22 November 1997 "until a date to be decided by a
future WRC".

The World Radiocommunication Conference (Geneva, 2007),

considering

*a)* that the band 47.2-50.2 GHz is allocated to the fixed, mobile and
fixed-satellite services on a co-primary basis;

*e)* that ITU‑R has completed studies dealing with sharing between
systems using HAPS in the fixed service and other types of systems in
the fixed service in the bands 47.2-47.5 GHz and 47.9-48.2 GHz,

recognizing

*a)* that the procedures of Article **9** have been applied on a
provisional basis from the end of WRC-97 through the end of WRC-07 for
coordination between satellite systems and systems using HAPS in the
bands 47.2-47.5 GHz and 47.9-48.2 GHz;

*b)* that with the suppression of Resolution **122 (Rev.WRC-03)** as of
the end of WRC-07, there is a need to provide coordination provisions
between satellite systems and systems using HAPS in the bands
47.2-47.5 GHz and 47.9-48.2 GHz in cases not presently covered under the
procedures of Article **9**;

*c)* that Nos. **9.17** and **9.18** apply for the coordination of
terrestrial stations, including HAPS, with earth stations, and vice

not presently addressed in Section II of Article **9**,

resolves

1 to encourage administrations to facilitate coordination between
systems in the fixed service using HAPS operating in the bands
47.2-47.5 GHz and 47.9-48.2 GHz and systems of the co‑primary satellite
services in the same bands;

2 that, before an administration notifies to the Bureau or brings into
use a frequency assignment in the bands 47.2-47.5 GHz and/or
47.9-48.2 GHz for a transmitting station in the fixed service which is
part of a high altitude platform network as defined by No. **1.66A,** it

1 to treat complete coordination information provided to it under
*resolves* 3 above in the manner in which No. **9.34** directs the
Bureau to treat complete information sent under No. **9.30** or
No. **9.32**;

2 to apply No. **9.40A** if the information provided to it under

**Reasons:** Incorporates into a new Resolution the coordination
provisions in Article 9 that are not already applicable by operation of
regulation to HAPS stations in the fixed service in the 47.2-47.5 GHz
and 47.9-48.2 GHz bands.

### Proposal for Agenda item 1.8, Resolution 145

Background information

Concerning Resolution 145, WRC-2000 decided to adopt provisions for the
operation of HAPS on a non-interfering/non-protected basis in the bands
27.5-28.35 and 31-31.3 GHz in Region 3, but did not allow operation in
the entire bands until studies could be completed to determine how best
to protect existing services in these and nearby frequency bands. WRC‑03
further refined these provisions by deciding to limit HAPS operation to
300 MHz in a specified direction in each of these two bands, retaining
the requirement for HAPS to operate on a non-interfering/non-protected
basis in these 300 MHz segments, and adopting Resolution 145 (WRC-03),
which created the possibility

of allowing Region 2 administrations to advise the Radiocommunication
Bureau of their intent to implement HAPS systems within the bands
27.5-28.35 and 31-31.3 GHz. Administrations intending to implement HAPS
in these bands are to seek the explicit agreement of concerned
administrations in accordance with *resolves* 4 of this Resolution.

Under Resolution 145 (WRC-03), the use of HAPS within the fixed-service
allocations within the 27.5-28.35 GHz and 31-31.3 GHz bands must be
limited to 300 MHz in each band, and is subject to the condition that
such use must not cause harmful interference to, nor claim protection
from, other stations of services operating in accordance with the Table
of Frequency Allocations of Article 5. Furthermore, the Resolution
specifies that that the development of these other services shall
proceed without constraints by HAPS operating pursuant to the
Resolution. This Resolution also calls for the identification of a
common 300 MHz within the 27.5-28.35 GHz band for use by HAPS. With
respect to the band 31-31.3 GHz, Resolution 145 (WRC-03) specifies that
systems using HAPS in Region 2 in the band 31-31.3 GHz must not cause
harmful interference to the radio astronomy service having a primary
allocation in the band 31.3-31.8 GHz, taking into account the protection
criterion given in Recommendation ITU‑R RA.769. The Resolution contains
limits on the level of unwanted power density into the HAPS ground
station antenna in the band 31.3-31.8 GHz in order to ensure the
protection of satellite passive services.

**5.537A** In Bhutan, Korea (Rep. of), the Russian Federation,
Indonesia, Iran (Islamic Republic of), Japan, Kazakhstan, Lesotho,
Malaysia, Maldives, Mongolia, Myanmar, Uzbekistan, Pakistan, the
Philippines, Kyrgyzstan, the Dem. People's Rep. of Korea, Sri Lanka,
Thailand and Viet Nam, the allocation to the fixed service in the
band 27.5-27.8 GHz may also be used by high altitude platform stations
(HAPS). Such use of 300 MHz of the fixed-service allocation by HAPS in
the above countries is further limited to operation in the
HAPS-to-ground direction and shall not cause harmful interference to,
nor claim protection from, other types of fixed-service systems or other
co-primary services. Furthermore, the development of these other
services shall not be constrained by HAPS. See Resolution **145
(Rev.WRC‑07)**.     (WRC‑07)

**Reasons:** WRC-03 called for the identification of a common 300 MHz
band, within the 27.5-28.35 GHz band, for use by HAPS in those countries
wishing to implement such service. Such identification will help to ease
the implementation and harmonization of HAPS in those countries.
Identifying the lowest 300 MHz segment for potential use by HAPS
maximizes the amount of contiguous FSS spectrum in the 27.5-30.0 GHz
band that would not be constrained domestically in any way as a
consequence of any potential use of the band by HAPS.

Thailand and Viet Nam, the allocation to the fixed service in the
band 31-31.3 GHz may also be used by systems using high altitude
platform stations (HAPS) in the ground-to-HAPS direction. The use of the
band 31-31.3 GHz by systems using HAPS is limited to the territory of
the countries listed above and shall not cause harmful interference to,
nor claim protection from, other types of fixed-service systems, systems
in the mobile service and systems operated under No. **5.545**.
Furthermore, the development of these services shall not be constrained
by HAPS. Systems using HAPS in the band 31-31.3 GHz shall not cause
harmful interference to the radio astronomy service having a primary
allocation in

the band 31.3-31.8 GHz, taking into account the protection criterion as
given in Recommendation ITU‑R RA.769. In order to ensure the protection
of satellite passive services, the level of unwanted power density into
a HAPS ground station antenna in the band 31.3-31.8 GHz shall be limited
to 106 dB(W/MHz) under clear-sky conditions, and may be increased up to
‑100 dB(W/MHz) under rainy conditions to take account of rain
attenuation, provided the effective impact on the passive satellite does
not exceed the impact under clear-sky conditions as given above. See

Article **5**;

*c)* that at WRC‑2000, several countries in Region 3 and one country in
Region 1 expressed a need for a lower frequency band for HAPS due to the
excessive rain attenuation that occurs at 47 GHz in these countries;

*d)* that some countries in Region 2 have also expressed an interest in
using a frequency range lower than those referred to in
*considering a)*;

*e)* that, in order to accommodate the need expressed by the countries
referred to in *considering c)*, WRC‑2000 adopted Nos. **5.537A** and
**5.543A**, which were modified at WRC-03 and then again at WRC-07 to
permit the use of HAPS in the fixed service in the band 27.5-27.8 GHz
and in the band 31-31.3 GHz in certain Region 3 countries and in one
Region 1 country on a non-harmful interference, non-protection basis;

*f)* that the bands 27.5-27.8 GHz and 31-31.3 GHz are already heavily
used or planned to be used by a number of different services and a
number of other types of applications in the fixed service;

*g)* that while the decision to deploy HAPS can be taken on a national
basis, such deployment may affect neighbouring administrations,
particularly in small countries;

*h)* that the 31.3-31.8 GHz band is allocated to the radio astronomy,
Earth exploration-satellite (passive) and space research (passive)
services, and that WRC-03 amended No. **5.543A** to specify signal
levels that would protect satellite passive services and radio astronomy
stations;

*i)* that ITU‑R has conducted studies dealing with sharing between
systems using HAPS in the fixed service and other types of systems in
the fixed service in the bands 27.5-27.8 GHz and 31-31.3 GHz leading to
Recommendation ITU‑R F.1609;

*j)* that results of some ITU‑R studies indicate that, in the bands
27.5-27.8 GHz and 31-31.3 GHz, sharing between fixed-service systems
using HAPS and other conventional fixed-service systems in the same area
will require appropriate interference mitigation techniques to be

## Agenda item 1.9

1.9 to review the technical, operational and regulatory provisions
applicable to the use of the band 2 500-2 690 MHz by space services in
order to facilitate sharing with current and future terrestrial services
without placing undue constraint on the services to which the band is
allocated

Background information

Issue A: Necessary power flux-density limits

There are three space services allocated in portions of the 2 500-2 690
MHz band. In addition to MSS there are allocations to BSS and FSS. At
WRC-03 the issue of sharing between terrestrial services and BSS (Sound)
was resolved as reflected in RR Nos. 5.417A and/or 5.418. The sharing
between BSS and terrestrial services not included in these two
provisions was not addressed at WRC-03 and need to be considered. WRC-03
recognized the need to review the technical, operational and regulatory
provisions applicable to the use of the band 2 500-2 690 MHz by space
services in order to facilitate sharing with current and future
terrestrial services (see Resolution 802 (WRC-03), Agenda item 1.9). To
that end, CPM06-1 established the Joint Task Group 6-8-9 (JTG 6-8-9)
with the purpose to conduct studies on this issue. The JTG 6-8-9 has
developed a methodology for estimating the satellite pfd values required
to protect terrestrial services. Based on this methodology, the United
States has determined that pfd values at the surface of the Earth
produced by the emissions of MSS, BSS and FSS satellites of --136
dB(W/m^2^/MHz) for angles of arrival below 5º and for angles of arrival
greater than 25º would yield tolerable levels of interference to the
fixed and non-IMT-2000 mobile services.

There are definite advantages to having a uniform regulatory regime for
all space services in the 2 500-2 690 MHz band, based on the
specification of a power flux-density limits in RR Article 21. First it
would ensure long-term safeguard of terrestrial systems in the band
2 500-2 690 MHz from satellite interference and could also be beneficial
to the long-term development of space services as a defined set of pfd
limits would be established and finalized. Additionally, a hard limit
regulatory regime would alleviate coordination burden and provide
regulatory certainty to all services in the band.

In short, the proposed regulatory approach would ensure that existing
and planned satellite networks are not overly constrained while existing
and future terrestrial services are adequately protected.

Issue B: Mobile-satellite service (MSS)

The band 2 500-2 520 MHz is allocated to MSS (space-to-Earth) paired
with MSS (Earth-to-space) allocation in the band 2 670-2 690 MHz.[^3]
The terrestrial services in these bands include the mobile and the fixed
services (including IMT-2000). Both the terrestrial mobile and fixed
services have been rapidly evolving to encompass high-speed mobile
Internet services requiring sensitive receiving equipment, which may be
highly susceptible to interference.

In general, co-frequency sharing between MSS and terrestrial services
has been found to be difficult by ITU‑R studies. SG 8, for example,
studied the feasibility of sharing between MSS and MS for IMT-2000 and
concluded that co-frequency/co-coverage sharing is not feasible. A new
regulatory provision is proposed that would limit MSS downlinks in the
2 500-2 520 MHz band to national and regional systems only. Under the
proposed regulatory provision, administrations

seeking to implement MSS will be allowed to do so while other
administrations will be able to implement terrestrial services, all
without the undue regulatory constraints. In case of a national system,
the service area of the MSS system would be limited to the territory
under the jurisdiction of the notifying administration. In case of a
regional system, the following Radio Regulations Board's decisions would
apply[^4]:

No. 5.2.1 applies to the interpretation of the word "regional" without a
capital "R".

When an administration submits a coordination request for a service area
that covers its national territory and extends beyond it, the
responsible administration, before it notifies the relevant assignments
under Article 11, will have to obtain agreements from those
administrations whose territories are included in the service area. When
the responsible administration notifies these assignments under Article
11, it shall submit the list of administrations that agreed to form the
regional system and shall adjust the service area accordingly. If no
agreement is obtained, the service area shall be limited to its national
territory.

It is also important to note that this rule of procedure clearly
stipulates that the service area of a national or regional satellite
system does not extend beyond the territory of administration(s) that
agreed to be included in that service area.

### Proposals associated with Issue A

ARTICLE 21

Terrestrial and space services sharing frequency bands above 1 GHz

Section V -- Limits of power flux-density from space stations

**MOD** USA/5/42

TABLE **21-4**     (WRC-03)

**Reasons:** Studies have shown that a satellite pfd value of --136
dB(W/m^2^/MHz) at angles below 5º, and --122 dB(W/m^2^/MHz) at angles
greater than 25º yielded acceptable levels of interference to
terrestrial services in the 2 500-2 690 MHz band. The proposed power
flux-density limits would facilitate FSS, BSS and MSS sharing with
current and future terrestrial services in the band 2 500-2 690 MHz and
provide necessary safeguard for the terrestrial (FS and MS) systems in
the band. The proposed modification would also provide regulatory
certainty to satellite services as a defined set of pfd limits would be
known and extensive coordination with uncertain outcome would not be
required.

*NOTE: The changes in portions of Article 5 shown under this proposal
are in addition to those changes shown to the same portion of Article 5
under other United States proposals.*

**Reasons:** Consequential to the addition of No. 5.403A.

**ADD** USA/5/45

**5.403A** The use of the band 2 500-2 520 MHz by the mobile-satellite
service is limited to national and regional systems, subject to
agreement obtained under No. 9.21.

**Reasons:** Restricting MSS to national and regional systems would
further facilitate sharing between MSS and terrestrial services. This
restriction would not constrain MSS, as there are no global coverage
systems planned for this band, but would ensure that MSS systems service
areas are limited to territories of the administrations seeking to
implement MSS. This restriction, however, would not fully address the
issue of MSS interference to terrestrial systems and must be implemented
in conjunction with the appropriate pfd limits for MSS (see proposed
modifications to Article 21).

## Agenda item 1.11

1.11 to review sharing criteria and regulatory provisions for protection
of terrestrial services, in particular the terrestrial television
broadcasting service, in the band 620-790 MHz from
broadcasting-satellite service networks and systems, in accordance with
Resolution **545 (WRC‑03)**

Background information

Under footnote No. 5.311, the band 620-790 MHz may be used for
assignments to television stations using frequency modulation in the BSS
(GSO or non-GSO). Since this band is extensively used by terrestrial
applications, Recommendation 705 (WARC-79) includes, among other things,
satellite pfd limits needed to protect the terrestrial services, in
particular, the terrestrial television broadcasting service that uses
this band extensively in all three Regions. It should also be noted that
there are allocations to the fixed and mobile services in some regions
in this band that also need to be addressed. In particular, some Region
2 administrations added their names to footnote No. 5.293 which
allocates the band to the fixed and mobile services on a primary basis
in several Region 2 countries.

In Region 2 the 620-790 MHz band is used extensively by free-to-air TV
systems. As a result of this extensive use of the 620-790 MHz band,
Region 2 administrations have not made allowances for external
interference in the deployment of their terrestrial TV systems or in the
development of their TV allotment plans or in the development of other
fixed and mobile services and therefore, there are no excess margins
which could have been used to accommodate additional interference from
systems in the BSS.

WRC-03 adopted a freeze on the processing of BSS satellite filings in
the band until the next WRC as per a new Resolution 545 (WRC-03) and
suspended the application of No. 5.311 and Recommendation 705 (WARC-79)
until that date. The Resolution was acceptable to all parties with the
understanding:

-- it allows for studies to continue on the appropriate protection
levels for the terrestrial broadcasting service (BS) to be determined;

-- it does not impact the Regional Planning Conference (RRC-06 and
Region 2 is not affected) for these services;

-- it places a moratorium on further deployments of BSS networks in
these bands until such studies are complete.

This proposal suppresses No. 5.311 and Resolution 545 to ensure the
complete protection of the current and future usage of the broadcasting,
mobile, and fixed services in the 620-790 MHz band from interference
from new broadcasting satellite operations in this same band. In
addition, the proposal adopts a new Resolution that would address
grandfathering of the existing Russian BSS networks operating in the
band. This proposal suppresses the BSS allocation and only allows the
grandfathered networks to continue to operate. This proposal aligns with
the Method B to resolve this Agenda item in the draft CPM Report to
WRC-07.

As a consequence, Recommendation 705 -- Criteria to be applied for
frequency sharing between the broadcasting-satellite service and the
terrestrial broadcasting service in the band 620-790 MHz, is deleted.

**SUP** USA/5/46

**5.311**

**Reasons:** Operators of TV broadcasting services do not have any
additional interference margins for the protection of terrestrial TV
broadcasting and therefore any additional interference from BSS will
place undue constraints on the existing and planned services TV
broadcasting services.

**SUP** USA/5/47

RECOMMENDATION 705

Criteria to be applied for frequency sharing between the\
broadcasting-satellite service and the terrestrial broadcasting\
service in the band 620-790 MHz[^5]

**Reasons:** Because the allocation to BSS is suppressed under this
proposal, there is no need for Recommendation 705 to be maintained.

**ADD** USA/5/48

Draft Resolution \[620-790 MHz\] (WRC-07)

Use of the frequency band 620-790 MHz for existing assignments\

(RRC-06) adopted an Agreement and associated Plans for digital
terrestrial broadcasting for Region 1, except Mongolia, and the Islamic
Republic of Iran in the frequency bands 174-230 MHz and 470-862 MHz;

*b)* that the above-mentioned Conference, in its Resolution **1**
**(RRC-06)** invited WRC-07, when considering Agenda item 1.11, to

*inter alia*, from the BSS GSO and non-GSO broadcasting-satellite
networks/systems operating or planned to be operated in the frequency
band 620-790 MHz;

*c)* that many administrations have extensive infrastructure for the
transmission and reception of analogue and digital television signals
between 620 MHz and 790 MHz;

*d)* that, as a result of the transition from analogue to digital
terrestrial television broadcasting, some countries are making the band
698-806 MHz available for applications in the mobile service,

recognizing

*a)* that in accordance with provision No. **5.311**, adopted at a
previous WARC several decades ago, two assignments to "Statsionar t" and

brought into use and their date of bringing into use confirmed before
the end of the World Radiocommunication Conference (Geneva, 2003)
(WRC‑03);

*b)* that, according to the records of the Bureau, there has been no
complaint of any harmful interference to or request for claiming
protection for these two assignments from the terrestrial television
systems of any administration,

further recognizing

*a)* that there is a need to authorize these two assignments to continue

## Agenda item 1.12

1.12 to consider possible changes in response to Resolution 86 (Rev.
Marrakesh, 2002) of the Plenipotentiary Conference: "Advance
publication, coordination, notification and recording procedures for
frequency assignments pertaining to satellite networks" in accordance
with Resolution **86** **(WRC‑03)**

### Proposal for Agenda item 1.12, Regulatory procedures and associated technical criteria applicable to satellite networks modification to Appendix 7, Table 10

Background information

Resolution 86 (Rev. Marrakesh, 2002) requested that WRC-03 and
subsequent conferences review the regulatory procedures associated with
the advance publication, coordination, notification and recording of
frequency assignments pertaining to satellite network. WRC-03 identified
in Resolution 86 (WRC‑03) the scope and the criteria to be used for the
implementation of Resolution 86 (Rev. Marrakesh, 2002). *Resolves* 1 of
Resolution 86 (WRC-03) specifically states that WRC-07 should "\[to\]
consider any proposals which deal with deficiencies in the advance
publication, coordination and notification procedures of the Radio
Regulations for space services which have either been identified by the
Board and included in the Rules of Procedure or which have been
identified by administrations or by the Radiocommunication Bureau, as
appropriate".

A review of Appendix 7, Table 10 (Predetermined coordination distance)
indicates that the case of ground-based earth stations and aircraft
terrestrial stations, except for those specifically identified cases in
the table, is missing. In the past the Radiocommunication Bureau has
used the predetermined distance of 500 km for this case, e.g. see
Document RRB98/134(Rev.1) dated 8 December 1998. This coordination
distance was derived assuming line-of-sight propagation between the
aircraft and ground-based stations with a 4/3 Earth radius and the
aircraft altitude of 12 km. The 500 km is consistent with the distance
currently applicable to the similar cases of coordination between
aircraft and ground-based stations such as i) ground-based earth
stations in the bands below 1 GHz to which No. 9.11A
applies/ground-based mobile in the bands within the range 1‑3 GHz to
which No. 9.11A applies and aircraft (mobile) terrestrial stations; ii)
aircraft (mobile) earth stations and ground-based terrestrial stations;
and iii) non-GSO MSS feeder-link earth stations and aircraft (mobile)
terrestrial stations. To cover the case of ground-based earth stations
and aircraft terrestrial stations, Table 10 needs to be modified to
include this case with a coordination distance of 500 km. The proposal
the United States makes here does not apply to frequency bands already
covered in Table 10.

### Proposal for Agenda item 1.12, Appendix 4, Annex 2 -- Characteristics of satellite networks, earth stations or radio astronomy stations

Background information

Resolution 86 (Rev. Marrakesh, 2002) requested that WRC-03 and
subsequent conferences review the regulatory procedures associated with
the advance publication, coordination, notification and recording of
frequency assignments pertaining to satellite network. WRC-03 identified
in Resolution 86 (WRC‑03) the scope and the criteria to be used for the
implementation of Resolution 86 (Rev. Marrakesh, 2002). *Resolves* 1 of
Resolution 86 (WRC-03) specifically states that WRC-07

should "\[to\] consider any proposals which deal with deficiencies in
the advance publication, coordination and notification procedures of the
Radio Regulations for space services which have either been identified
by the Board and included in the Rules of Procedure or which have been
identified by administrations or by the Radiocommunication Bureau, as
appropriate".

Currently, Appendix 4 makes certain data elements optional for the case
of "Advance publication of a non-geostationary-satellite network not
subject to coordination under Section II of Article 9". These fields
include i) the necessary bandwidth; ii) the carrier frequency or
frequencies of the emission; iii) the maximum value of the peak envelope
power, in dBW, supplied to the input of the antenna for each carrier
type; iv) the minimum value of the peak envelope power, in dBW, supplied
to the input of the antenna for each carrier type; v) the minimum power
density, in dB(W/Hz), supplied to the input of the antenna for each
carrier type; and vi) the required *C*/*N* ratio. This information is
required in order to determine whether unacceptable interference may be
caused by the planned satellite network or system and communicate this
information to the publishing administration and the Bureau under
No. 9.3. To only require this information at the notification stage
makes any analysis too late to benefit either administration. While most
administrations have been supplying this data as part of the Advance
Publication Information (API), there have been instances where the
information was not made available. Therefore modifications to Appendix
4 are necessary to allow necessary analysis to take place during API.

### Proposal for Agenda item 1.12, Coordination of the radionavigation-satellite service (space-to-space) in the bands 1 215-1 300 MHz and 1 559-1 610 MHz

Background information

The scope and criteria to be used for the implementation of Resolution
86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference by future
world radiocommunication conferences (WRCs) is established in Resolution
86 (WRC‑03). *Resolves* 1 of Resolution 86 (WRC-03) relates to the
consideration of proposals dealing with deficiencies in the advance
publication, coordination and notification procedures of the Radio
Regulations for space services, and *resolves* 2 relates to
consideration of proposals intended to transform the content of the
Rules of Procedure into regulatory text.

WRC-2000 added the space-to-space direction to the existing
radionavigation-satellite service (RNSS) (space-to-Earth) allocations in
the bands 1 215-1 300 MHz and 1 559-1 610 MHz, along with footnote
5.329A. WRC-03 added footnote 5.328B, which applied coordination between
two non-GSO RNSS systems and between non-GSO and GSO RNSS systems in the
bands 1 164-1 300 MHz, 1 559-1 610 MHz and 5 010-5 030 MHz under
Nos. 9.12, 9.12A and 9.13 after 1 January 2005, without specifying
direction (i.e. space-to-Earth or space-to-space). Coordination between
GSO RNSS systems in the same bands (space-to-Earth and space-to-space)
is covered by No. 9.7, again without specifying direction (i.e.
space-to-Earth or space-to-space).

No. 9.11A applies the coordination provisions of Nos. 9.12 to 9.16 where
the requirement to coordinate is included in a footnote to the Table of
Frequency Allocations referring to No. 9.11A. Since WRC-2000, the Rules
of Procedure (RoP), issued by the Radio Regulations Board (RRB), rather
than the Radio Regulations have defined the services and frequency bands
for which the coordination procedure under No. 9.11A is required. The
RRB considered the application of No. 9.11A to the bands given in
No. 5.329A (i.e. 1 215-1 300 and 1 559-1 610 MHz) and interpreted the
Regulations as excluding RNSS (space-to-space) assignments in the bands
given in No. 5.329A from any obligation to coordinate with other
services and with RNSS (space-to-Earth), but as obliging these RNSS
(space-to-space) assignments to coordinate with each other.

In addition, many RNSS (space-to-space) network assignments are
receive-only in the bands 1 215-1 300 MHz and 1 559-1 610 MHz.
Resolution 610 (WRC-03), as referenced in No. 5.328B, requires
administrations to provide evidence of binding agreements for the
manufacture, procurement, and launch of RNSS systems and networks. This
resolution was intended to aid bilateral coordination between
transmitting RNSS systems and networks by ensuring such systems are
either in operation or in the process of being implemented. Requiring
Resolution 610 (WRC-03) data for receiving space stations is
unnecessary.

Therefore, modifications to No. 5.329A and No. 5.328B are needed to
reflect the RRB decision that requires RNSS (space-to-space) to
coordinate only with other RNSS (space-to-space) but not with other
services or with RNSS (space-to-Earth), and to remove Resolution 610
(WRC-03) obligations from RNSS receiving space stations. Additionally,
to ensure that the obligation on RNSS (space-to-space) networks under
No. 5.329A is also adequately reflected for geostationary RNSS
(space-to-space) networks with respect to GSO RNSS (space-to-Earth)
networks in the 1 215-1 300 MHz and 1 559-1 610 MHz bands (a
coordination scenario not encompassed by Nos. 9.12, 9.12A, and 9.13),
the modification to No. 5.328B refers as well to No. 9.7.

article 5

Frequency allocations

Section IV -- Table of Frequency Allocations\
(See No. 2.1)

**MOD** USA/5/52

**5.329A** Use of systems in the radionavigation-satellite service
(space-to-space) operating in the bands 1 215-1 300 MHz and 1 559-1 610
MHz is not intended to provide safety service applications, and shall
not impose any additional constraints on radionavigation-satellite
service (space-to-Earth) systems or on other services operating in
accordance with the Table.     (WRC‑2000)

**Reasons:** To clarify that "other systems" in No. 5.329A refers to the
radionavigation-satellite service (space-to-Earth) and that "services"
refers to services other than the radionavigation-satellite service.

**MOD** USA/5/53

**5.328B** The use of the bands 1 164-1 300 MHz, 1 559-1 610 MHz and
5 010-5 030 MHz by systems and networks in the radionavigation-satellite
service for which complete coordination or notification information, as
appropriate, is received by the Radiocommunication Bureau after
1 January 2005 is subject to the application of the provisions of
Nos. **9.12**, **9.12A** and **9.13**. Resolution **610** **(WRC‑03)**
shall also apply; however, in the case of radionavigation-satellite
service (space-to-space) networks and systems, Resolution **610
(WRC-03)** shall only apply to transmitting space stations. In
accordance with No. **5.329A**, for systems and networks in the
radionavigation-satellite service (space-to-space) in the bands
1 215‑1 300 MHz and 1 559-1 610 MHz the provisions of Nos. **9.7**,
**9.12**, **9.12A** and **9.13** shall only apply with respect to other
systems and networks in the radionavigation-satellite service
(space-to-space).     (WRC-07)

**Reasons:** To make it clear that the application of the coordination
procedure in Nos. 9.7, 9.12, 9.12A and 9.13 to RNSS (space-to-space)
systems and networks is only with respect to other
radionavigation-satellite service (space-to-space) systems and networks
in the bands 1 215-1 300 MHz and 1 559-1 610 MHz and to limit the
application of Resolution 610 (WRC-03) to transmitting space stations.

### Proposal for Agenda item 1.12, Coordination arc in the band 17.3-17.8 GHz and other closely related proposals

Background information

Resolution 901 (WRC-03) invites ITU‑R "to conduct studies on the
applicability of the coordination arc concept for space
radiocommunication services not yet covered by these Regulations" as
well as "to recommend, as appropriate, the orbital separation required
for triggering inter-service and intra-service coordination concerning
the satellite services in frequency bands above 3.4 GHz for
geostationary-satellite (GSO) networks not subject to a Plan and not
already covered by the coordination arc concept specified in No. **9.7**
(GSO/GSO) of Table 5-1 (Appendix **5**), under items 1), 2) and 3) of
the frequency band column, and subject to Section II of Article 9". This
Resolution further *resolves* to recommend that a future competent
conference review the results of ITU‑R studies on the application of the
coordination arc and consider including the results of these studies in
Appendix 5. Review of such study results are considered under Resolution
86 of Agenda item 1.12.

Pursuant to Resolution 901, ITU‑R studied the appropriate coordination
arc value to trigger coordination between broadcasting-satellite service
(BSS) networks serving Region 2 in the band 17.3-17.8 GHz and
fixed-satellite service (FSS) (space-to-Earth) networks serving Region 1
in the band 17.3-17.7 GHz and FSS (space-to-Earth) networks serving
Regions 1, 2 and 3 in the band 17.7-17.8 GHz.

ITU‑R studies concluded that a coordination arc value of ±8° is
appropriate to trigger coordination between GSO BSS networks serving
Region 2 and GSO FSS (space-to-Earth) networks whose service areas are
limited to Region 1 in the band 17.3-17.7 GHz and between GSO BSS
networks serving Region 2 and GSO FSS (space-to-Earth) networks whose
service areas are limited to Regions 1 and/or 3 in the band
17.7-17.8 GHz. As a result, specific changes are proposed to Table 5-1
of Appendix 5 to incorporate these conclusions. For the case of Region 2
FSS (space-to-Earth) with respect to Region 2 BSS in the 17.7‑17.8 GHz
band footnote No. 5.517 applies.

**5.517** In Region 2, the allocation to the broadcasting-satellite
service in the band 17.3-17.8 GHz shall come into effect on 1 April
2007. After that date, use of the fixed-satellite (space-to-Earth)
service in the band 17.7-17.8 GHz shall not claim protection from and
shall not cause harmful interference to operating systems in the
broadcasting-satellite service.

Changes to the wording of this provision, as well as consequential
changes to the Table of Frequency Allocations are proposed recognizing
that the 1 April 2007 date has passed.

Finally, also for Region 2, No. 5.518 applies for the mobile service.

**5.518** *Different category of service:  *in Region 2, the allocation
of the band 17.7-17.8 GHz to the mobile service is on a primary basis
until 31 March 2007.

Suppression of this provision is proposed, recognizing that the 31 March
2007 date has passed.

**Reasons:** These modifications to Table 5-1 of Appendix 5 incorporate
the results of ITU‑R studies that conclude that a coordination arc of
±8º between Region 2 BSS and Regions 1 and 3 FSS in the bands
17.3-17.8 GHz is sufficient for triggering coordination between these
services. These modifications also note that No. 5.517 applies in the
band 17.7-17.8 GHz.

## Agenda item 1.14

1.14 to review the operational procedures and requirements of the Global
Maritime Distress and Safety System (GMDSS) and other related provisions
of the Radio Regulations, taking into account Resolutions **331
(Rev.WRC‑03)** and **342 (Rev.WRC‑2000)** and the continued transition
to the GMDSS, the experience since its introduction, and the needs of
all classes of ships

Background information

Resolution 342 -- New technologies to provide improved efficiency in the
use of the band 156-174 MHz in the maritime mobile service, considers
the need for new maritime technologies which use the bands described by
Appendix 18 of the Radio Regulations. *Considering k*) of this
Resolution in particular addresses the new automatic identification
system (AIS) developed by ITU‑R and the need to provide full worldwide
interoperability of equipment on ships.

AIS is an international standard for ship-to-ship, ship-to-shore and
shore-to-ship communication of information, including vessel position,
speed, course, destination and other data defined by ITU‑R
Recommendation M.1371-1. AIS transmits on 161.975 MHz and 162.025 MHz,
as specified by Appendix 18 of the Radio Regulations and by
Recommendation ITU‑R M.1371-1. AIS was originally designed to enhance
navigation safety, but its potential as a prime contributor to security
quickly became apparent. AIS provides an effective means to monitor the
total global marine environment that could affect the security, safety,
economy, or environment of an administration.

On 6 December 2000, the International Maritime Organization (IMO)
amended Chapter V of the Safety of Life at Sea (SOLAS) Convention to
include an implementation schedule for shipboard AIS carriage
requirements. In 2002, in response to the needs of administrations to
improve their security, the IMO accelerated the AIS carriage
requirements schedule from a phased approach ending in 2008, to require
all vessels over 300 gross tons on international voyages to carry AIS
equipment by 31 December 2004.

In order to locate and identify vessels for security purposes beyond VHF
range of shore, the United States plans to install AIS receivers on
aircraft and on low earth orbit mobile satellite platforms. Norway is
performing similar evaluations using satellite detection of AIS, as
demonstrated to the International Maritime Organization's Communications
and Search and Rescue Subcommittee meeting of February 2005. Satellite
use is not currently allocated in Article 5.

**Reasons: The specific footnote is modified below.**

**MOD** USA/5/60

**5.226** The frequency 156.8 MHz is the international distress, safety
and calling frequency for the maritime mobile VHF radiotelephone
service. The conditions for the use of this frequency are contained in
Article **31** and Appendix **13**.

In the bands 156-156.7625 MHz, 156.8375-157.45 MHz, 160.6-160.975 MHz
and 161.475-162.05 MHz, each administration shall give priority to the
maritime mobile service on only such frequencies as are assigned to
stations of the maritime mobile service by the administration (see
Articles **31** and **52**, and Appendices **13** and **18**).

Any use of frequencies in these bands by stations of other services to
which they are allocated should be avoided in areas where such use might
cause harmful interference to the maritime mobile VHF radio­communication
service.

However, the frequency 156.8 MHz and the frequency bands in which
priority is given to the maritime mobile service may be used for
radiocommunications on inland waterways subject to agreement between
interested and affected administrations and taking into account current
frequency usage and existing agreements.

**Reasons:** The addition of a reference Appendix 18 to the second
paragraph is needed.

**ADD** USA/5/61

**5.226X** In the maritime mobile service the frequency 162.025 (AIS 2)
MHz shall be used exclusively for automatic identification systems (AIS)
(see Appendix **18**). The band 162.0125-162.0375 MHz is also allocated
on a primary basis to the maritime mobile-satellite service
(Earth-to-space) for reception by satellites of emissions from the AIS
transmitting at 162.025 MHz (AIS 2).

Any use of frequencies in these bands by stations of other services to
which they are allocated should be avoided in areas where such use might
cause harmful interference to the maritime mobile and maritime
mobile-satellite service at 162.025 MHz (AIS 2).

**Reasons:** AIS is a navigation safety and security system, with
frequencies specified in Appendix 18. Low-Earth orbit mobile satellites
are used to detect AIS transmissions from ships of vessel identification
and location, for purposes of security, safety and environmental
protection.

## Agenda item 1.17

1.17 to consider the results of ITU‑R studies on compatibility between
the fixed-satellite service and other services around 1.4 GHz, in
accordance with Resolution **745** **(WRC‑03)**

Background information

WRC-03 made a conditional secondary allocation to the fixed-satellite
service (FSS) for feeder links for non‑geostationary-satellite (non-GSO)
networks in the mobile-satellite service (MSS) with service links below
1 GHz (non-GSO-MSS) through RR No. 5.339A in the bands 1 390-1 392 MHz
(Earth-to-space) and 1 430-1 432 MHz (space-to-Earth). However, due to
the fact that there were insufficient and/or incomplete studies and test
measurements with regard to the protection of other services with
allocations in these bands or in the nearby passive band 1 400-1 427
MHz, Resolution 745 (WRC-03**)** resolves that these feeder-link
allocations shall not be used until the completion of all studies and
the results of these studies reported to WRC‑07.

The frequency band 1 350-1 400 MHz is allocated worldwide on a primary
basis to the radiolocation service (RLS) and in Region 1 to the fixed
and mobile services. The band 1 370-1 400 MHz is allocated worldwide on
a secondary basis to the space research (SRS) (passive) and Earth
exploration-satellite (EESS) (passive) services by RR No. 5.339. The
band 1 330-1 400 MHz is also used by the radio astronomy service (RAS)
for observations of the red-shifted neutral hydrogen line and No. 5.149
urges administrations to take all practicable steps to protect it from
harmful interference.

The band 1 400-1 427 MHz is allocated to the EESS (passive), the RAS and
the SRS (passive) on a worldwide basis. For the RAS, this band is the
most important band for studies of the hydrogen line and for continuum
observations. This band is also used worldwide for the very long
baseline interferometry (VLBI) technique which is utilized for radio
astronomical studies requiring high angular resolution. For the EESS
(passive), the band 1 400-1 427 MHz is a vital resource for measuring
ocean salinity and soil moisture content of the Earth. This band is one
of the select bands for which RR No. 5.340 prohibits all emissions,
emphasizing its particular importance for the science community.

The band 1 427-1 452 MHz is allocated on a primary basis to the fixed
and mobile services worldwide. The band 1 427-1 429 MHz is also
allocated on a primary basis to the space operation service
(Earth-to-space) in all three Regions. Additionally, RR No. 5.342
allocates the band 1 429-1 535 MHz on a primary basis in some
administrations to the aeronautical mobile service exclusively for the
purposes of aeronautical telemetry within their national territory.

A Band 1 430-1 432 MHz (feeder-link downlink)

Since the non-GSO-MSS feeder links are allocated on a secondary basis,
they cannot cause harmful interference to nor claim protection from the
fixed and mobile services in this band. ITU‑R studies based on the
fractional degradation of performance criterion used by the fixed
service have concluded that a pfd limit of --164 dB(W/m^2^) in a 4 kHz
bandwidth should be adequate to protect the fixed service, as well as
the mobile service.

In addition, ITU‑R studies have shown that the pfd limits are necessary
to protect the aeronautical telemetry systems used under the mobile
service in the territory of countries identified in RR No. 5.342:

--181       dB(W/m^2^) 0 ≤ α ≤ 4

--193 +20 log α       dB(W/m^2^) 4 \< α ≤ 20

--213.3 + 35.6 log α       dB(W/m^2^) 20 \< α ≤ 60

--150       dB(W/m^2^) 60 \< α ≤ 90

where α is the angle of arrival (degrees above the horizontal plane).

To protect the RAS operations in the band 1 400-1 427 MHz, studies in
ITU‑R have resulted in Recommendation ITU‑R M.8/102(Rev.1) which
recommends the following epfd limits:

an epfd of --259 dB(W/m^2^) in any 20 kHz bandwidth of the band
1 400-1 427 MHz for more than 98% of integration periods of 2 000
seconds for spectral-line observations; and

an epfd of --243 dBW/m^2^ in the entire 1 400-1 427 MHz band for more
than 98% of integration periods of 2 000 seconds for continuum
(broadband) observations.

Studies in ITU‑R have resulted in Recommendation ITU‑R M.8/101(Rev.1)
which recommends that an unwanted emission power limit of --46 dBW in
the passive band 1 400-1 427 MHz at the satellite antenna port would be
sufficient to protect all EESS systems which are expected to use the
band.

No studies have been done concerning the space operations service
(Earth-to-space) operating in the 1 427-1 429 MHz band due to the lack
of participation from service providers who would be using the
non-GSO-MSS allocation.

B Band 1 390-1 392 MHz (feeder-link uplink)

The protection of the fixed and mobile services within the band
1 390-1 392 MHz can be accomplished by requiring appropriate separation
distances between the non-GSO-MSS feeder-link earth stations and the
fixed and mobile stations. However, detailed information on these
separation distances is not available in any ITU‑R studies at this time.

The protection of the radiolocation service stations operating in the
1 350-1 400 MHz band has not been extensively studied. However, an ITU‑R
study on the compatibility of the non-GSO-MSS feeder-link uplinks that
may operate in the 1 390-1 392 MHz band with aeronautical radiolocation
receivers indicates that the interference from the non-GSO-MSS
feeder-link uplinks exceeds the aeronautical radiolocation receivers
interference criteria by anywhere from 37.9 dB to as much as 85.4 dB.
The study concludes that sharing is not feasible between these two types
of systems.

To protect the radio astronomy service operations in the 1 330-1 400 MHz
band, Recommendation ITU‑R M.8/102(Rev.1) recommends that the
non-GSO-MSS feeder-link earth stations be separated from radio astronomy
stations which conduct observations in the band 1 400-1 427 MHz, such
that the total data loss due to feeder-link uplink and downlink
emissions does not exceed 2%.

To protect the EESS (passive) operations in the band 1 400-1 427 MHz,
Recommendation ITU‑R M.8/101(Rev.1) recommends that an unwanted emission
power limit of --63 dBW in the passive band 1 400-1 427 MHz at the
antenna port of the non-GSO-MSS feeder-link earth station would be
sufficient to protect all EESS passive sensors which are expected to use
the band.

An ITU‑R study was done on the potential interference from non-GSO-MSS
feeder-link uplinks that may operate in the 1 390-1 392 MHz band into
passive sensors operating in the secondary allocation to EESS (passive)
in the 1 370-1 400 MHz band. The results of this study indicate that the
co-channel interference into the passive sensor would exceed the
interference threshold by as much as 82 dB and as often as 42% of the
time.

Summary

From these study results given in Resolution 745 (WRC-03), it is likely
that the non-GSO-MSS feeder links will be able to use the allocated
bands only with significant constraints required to protect the existing
services. It is clear that some studies have indicated problems sharing
the 1 390-1 392 MHz band with existing services. Furthermore, no service
providers are continuing to pursue opportunities or participating in
relevant studies to use this allocation. Their absence indicates a lack
of need for the allocation. Therefore, suppression of the conditional
allocation to the non-GSO-MSS feeder-link allocations in the 1 390-1 392
MHz and 1 430-1 432 MHz bands is proposed.

The absence of non-GSO-MSS interests indicated the lack of need for the
allocation.

## Agenda item 1.18

1.18 to review pfd limits in the band 17.7-19.7 GHz for satellite
systems using highly inclined orbits, in accordance with
Resolution **141 (WRC‑03)**

Background information

ITU‑R has been considering sharing aspects for non-GSO systems using
highly-inclined orbits (HIOs), including systems in highly elliptical
orbit, for a number of years. Several categories of non-GSOs are
encompassed within the term "highly-inclined". WRC-95 adopted
provisional limits on the pfd produced at the surface of the Earth by
non-GSO satellites operating in the FSS (space-to-Earth) in the band
17.7-19.7 GHz in order to protect terrestrial services. These limits
were revised at WRC-97 and WRC-2000. WRC-03 determined that no changes
were needed to the pfd limits and associated provisions in Section V of
Article 21 that were finalized at WRC-2000 for all non-GSO FSS systems
in the 17.7-19.7 GHz band. WRC-03 adopted Resolution 141 (WRC-03), which
invites ITU‑R to conduct studies to determine whether the current pfd
limits in Article 21 for non-GSO systems in the FSS are adequate to
protect the fixed service in the 17.7-19.7 GHz band from
non-geostationary systems using HIOs. Resolution 141 (WRC-03) also
invites ITU‑R to determine whether there are technical and operational
measures that could be implemented by the fixed service to mitigate
interference from FSS space stations in HIO. Studies presented to ITU in
preparation for WRC-07 show conclusively that the current pfd limits in
Table 21-4 of Article 21 are adequate to protect the fixed service in
the 17.7-19.7 GHz band.

ARTICLE 21

Terrestrial and space services sharing frequency bands above 1 GHz

Section V -- Limits of power flux-density from space stations

**[NOC]{.underline}** USA/5/68

TABLE **21-4***  *(*continued*)     (WRC-03)

**Reasons:** The current pfd limits and associated provisions in Section
V of Article 21 are adequate to protect the fixed service in the
17.7-19.7 GHz band from non‑GSO satellite systems, including those using
highly-inclined orbits having an apogee altitude greater than 18 000 km
and an orbital inclination between 35 and 145. Satellite networks using
HIOs should continue to be considered as non-GSOs and have the same
regulatory standing as other types of non-GSOs. No additional regulatory
provisions are needed.

**SUP** USA/5/69

RESOLUTION 141 (WRC‑03)

Sharing between certain types of non-geostationary-satellite systems\
in the fixed-satellite service and stations in the fixed service\
in the 17.7-19.7 GHz band

**Reasons:** All of the actions required under this Resolution have been
completed and it may be suppressed. The technical studies confirmed that
the current pfd limits for non‑GSO FSS systems in Article 21 are
adequate to protect the fixed service in the 17.7-19.7 GHz band from
non-GSO systems having an apogee altitude greater than 18 000 km and an
orbital inclination between 35 and 145. There is no need to review or
revise any findings made on the compliance with the limits contained in
Article 21 of a non‑GSO FSS system for which complete advance
publication information has not been received prior to 5 July 2003 per
the instructs the Radiocommunication Bureau.

## Agenda item 1.19

1.19 to consider the results of the ITU‑R studies regarding spectrum
requirement for global broadband satellite systems in order to identify
possible global harmonized fixed-satellite service frequency bands for
the use of Internet applications, and consider the appropriate
regulatory/technical provisions, taking also into account No. **5.516B**

Background information

WRC-03 adopted this Agenda item which relates to the identification of
globally harmonized fixed-satellite service (FSS) frequency bands for
broadband applications via satellite. It is important to note that all
FSS frequency bands, including the bands, listed in No. 5.516B, can be
and in many cases are used for Internet applications.

ITU‑R Working Party 4A has the lead in preparing the technical basis for
this Agenda item at WRC‑07. It has carried out a number of studies at
its last three meetings and has prepared draft CPM text. The studies
have examined the issues associated with this Agenda item. These include
the question of harmonized frequency bands and the status of Internet
applications being implemented in FSS bands.

The initial global spectrum allocations for FSS were made at WARC-71,
and WARC-79. These included spectrum through the 20/30 GHz range.
Additional global allocations to the FSS were made in the 40/50 GHz
range at subsequent conferences. Many of these bands are heavily
utilized delivering a diversity of services. The FSS allocations are
being used by over 200 geostationary radiocommunication satellites
including those indicated in No. 5.516B identified for use in
high-density applications. Most of the FSS allocations are global in
nature and therefore harmonized in all three ITU‑R Regions.

There has been a proliferation of different size earth stations for
different types of applications during the last 25 years these
allocations have been available. As these applications have evolved so
too have the basic Radio Regulations to provide for them. Access to the
Internet using FSS satellite systems is being implemented in a number of
ways. Examples are illustrated in the table below.

  ---------------------------- ------------------- -----------------------
  Application                  Bands               Example terminal size

  Direct-to business or        11/14 GHz\          1.2 m\
  residence                    20/30 GHz           0.6 m

  ESV                          4/6, 11/14 GHz      2.4 m, 1.2 m

  Bundled with TV services     11/14 GHz\          0.6-2.4 m\
                               20/30 GHz           0.6 m

  V-sat connected to an RLAN   11/14 GHz           0.6-2.4 m
  ---------------------------- ------------------- -----------------------

As illustrated in the table there has been a variety of Internet
applications which have developed. These have taken place within the
harmonized regional allocations to the FSS. Today's service provider
often initiates an Internet service using only a few transponders
(partial sections of a satellite) of a satellite for economic reasons
rather than incurring the capital expense of a whole satellite for a
single type of application. In addition, ground equipment suitable for
broadband/Internet applications can be adapted to other bands, and as
Internet applications are being pursued in a wide range of FSS
allocations, it would be counter-productive to identify any subset of
frequencies especially for Internet applications.

The current Radio Regulations for access, coordination and notification
of satellite networks fully accommodate the ability of FSS systems to
provide Internet access. In addition, commercially available ground
equipment suitable for broadband/Internet applications is frequency
agile and is fully capable of operating with the existing and planned
FSS satellite systems in the allocated frequency bands.

**[NOC]{.underline}** USA/5/70

The United States proposes that there be no changes to Article 5,
Section IV -- Table of Frequency Allocations, nor any regulatory or
procedural action be taken by WRC-07 in response to this Agenda item.

**Reasons:** There are many existing and planned FSS satellite systems
in a number of different FSS frequency bands that carry Internet
applications. They are in use and will continue to be used on a
worldwide basis in the 4/6 GHz, 11/14 GHz, and 20/30 GHz allocations.
The identification of specific FSS frequency bands for Internet
applications will not improve nor will it facilitate the provision of
these applications. Consequently, no changes to the Radio Regulations
are necessary.

## Agenda item 2

2 to examine the revised ITU‑R Recommendations incorporated by reference
in the Radio Regulations communicated by the Radiocommunication
Assembly, in accordance with Resolution **28 (Rev.WRC‑03)**, and to
decide whether or not to update the corresponding references in the
Radio Regulations, in accordance with principles contained in the Annex
to Resolution **27** **(Rev.WRC‑03)**

Background information

Agenda item 1.15 of WRC-03 dealt with RNSS matters as indicated in
Resolutions 604 (WRC‑2000), 605 (WRC-2000), and Resolution 606
(WRC-2000).

Resolution 605 concerned the development and implementation of
regulations to provide protection for the ARNS in the band 1 164-1 215
MHz from all the emissions of "real" RNSS systems in the band. To this
end No. 5.328A was adopted and is associated with the referenced
allocation. It states:

**5.328A** Stations in the radionavigation-satellite service in the band
1 164-1 215 MHz shall operate in accordance with the provisions of
Resolution **609 (WRC‑03)** and shall not claim protection from stations
in the aeronautical radionavigation service in the band 960-1 215 MHz.
No. **5.43A** does not apply. The provisions of No. **21.18** shall
apply.     (WRC-03)

The language of this footnote regulation mandates that the RNSS in the
band 1 164-1 215, "shall" operate in accordance with the provisions of
Resolution 609 (WRC-03). This resolution is entitled: Protection of
aeronautical radionavigation service systems from the equivalent power
flux-density produced by radionavigation-satellite service networks and
systems in the 1 164-1 215 MHz frequency band. *Resolves* 10 of this
mandatory Resolution states:

10 that the methodology and the reference worst-case ARNS system antenna
contained in Recommendation ITU‑R M.1642 shall be used by
administrations for calculating the aggregate epfd produced by all the
space stations within all RNSS systems in the band 1 164-1 215 MHz,

As indicated the statement "shall be used" in relation to Recommendation
ITU‑R M.1642 clearly makes use of this recommendation mandatory in the
context of the Radio Regulations, and therefore must be considered part
of them.

Resolution 27 and its Annex set forth the criteria for Recommendations
and Resolutions to be: Incorporated by Reference. Clearly,
Recommendation ITU‑R M.1642 meets these criteria.

As a consequence it is mandatory that this recommendation be considered
as part of Volume 4 of the Radio Regulations although it is not now.
Recommendation ITU‑R M.1642 must be included in subsequent revisions of
Volume 4 of the Radio Regulations.

It should be noted that a Working Party of the Special Committee has
come to the same conclusion regarding the incorporation in Volume 4 of
the Radio Regulations of the referenced Recommendation as reflected in
the Attachment to Annex 15 of Document SC-WP/57.

**ADD** USA/5/71

Recommendation ITU‑R M.1642 -- Methodology for assessing the maximum
aggregate equivalent power flux-density at an aeronautical
radionavigation service station from all radionavigation-satellite
service systems operating in the 1 164-1 215 MHz band, is required to be
added to Volume 4, ITU‑R Recommendations incorporated by reference. A
copy of Recommendation ITU‑R M.1642 will be made available to the
Conference in accordance with the provisions of Annex 3 to Resolution
27.

**Reasons:** Recommendation ITU‑R M.1642 fulfils all of the criteria for
a recommendation which is incorporated by reference as set forth in
Resolution 27 and its Annex, and therefore must be included in Volume 4
of the Radio Regulations.
