**FCC SEEKS COMMENT ON RECOMMENDATIONS APPROVED BY THE ADVISORY
COMMITTEE FOR THE 2007 WORLD RADIOCOMMUNICATION CONFERENCE**

**IB Docket No. 04-286**

On December 13, 2006, the World Radiocommunication Conference Advisory
Committee (WRC-07 Advisory Committee) approved and submitted for
Commission's consideration its recommendations with regard to a number
of issues that will be considered by the 2007 World Radiocommunication
Conference (WRC-07).[^1] These recommendations are attached to this
Public Notice.

Based upon an initial review of the attached WRC-07 Advisory Committee
recommendations, the International Bureau, in coordination with other
FCC Bureaus and Offices, tentatively concludes that it can generally
support these recommendations. We do, however, have some reservations
about the proposals reflected in documents WAC/147. The International
Bureau also notes the differing views expressed by WRC-07 Advisory
Committee participants in documents WAC/148, WAC/149 and WAC/150.

The FCC seeks comment on the attached recommendations as well as
recommendations that appear in all of the WRC-07 Advisory Committee
documents.[^2] The FCC also seeks comment on the attached draft
preliminary views and proposals that have been developed by the
Executive Branch Agencies and submitted to the FCC by the National
Telecommunications and Information Administration (NTIA). Finally, the
FCC seeks comment on the International Bureau's initial conclusions with
regard to the WRC-07 Advisory Committee recommendations.

The comments provided by interested parties will assist the FCC in its
upcoming consultations with the U.S. Department of State and NTIA in the
development of U.S. positions for WRC-07. As the recommendations that
are attached to this Public Notice may evolve in the course of
interagency discussions as WRC‑07 nears, they do not constitute final
U.S. Government position on any issue.

I.  **Recommendations by the Advisory Committee for the 2007 World
    Radiocommunication Conference:**

**[INFORMAL WORKING GROUP 1 (IWG-1)]{.underline}**

**[Terrestrial and Space Science Services]{.underline}**

**Document WAC/151(13.12.06):**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Agenda Item 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)**;

**Background Information:** This proposal addresses Resolution **742**
**(WRC‑03), "**consideration of sharing criteria between the passive
services and the fixed and mobile services in the band 36-37 GHz to
determine appropriate sharing criteria and to consider the possible
inclusion of such sharing criteria within the Radio Regulations."

The frequency band 36-37 GHz is allocated to the Earth
exploration-satellite (passive), the space research (passive), the fixed
and the mobile services on a primary basis. This band has been used for
passive sensing of the Earth and its atmosphere for many years. It is an
important resource for remote sensing of rain rates, snow, sea ice and
clouds and is often used in conjunction with a number of other passive
sensing bands to extract such data. A variety of scientific and
meteorological spacecraft carry instruments that utilize this band.
There is limited use of the band by the fixed or mobile services.
However, determination of appropriate sharing criteria should not place
undue constraints on the future use of the band by the fixed and mobile
services.

The ITU-R has undertaken studies that should result in Recommendations
in Study Group 9 and Study Group 7, which would recommend various
interference mitigation measures to be taken. These studies indicate
that passive sensing systems may receive excessive interference if there
are no limitations on the power of fixed and mobile service transmitters
as deployment densities of the terrestrial services in this band
increase. Based on the results of these studies, a new footnote in
Article **5** of the Radio Regulations should be added, containing
appropriate transmitter power limits on future systems operating in the
36-37 GHz band for the fixed and mobile services.

operational environment to protect the future use of Earth
exploration-satellite (passive) and space research (passive) services in
this band without imposing undue constraints on the fixed or mobile
services[. Moreover, implementation of this power limit is sufficient to
protect the passive services; no unwanted emissions requirements would
be necessary]{.underline}~~.~~

**Document WAC/147(13.12.06):**

**DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE**

**Agenda Item 7.2:** to recommend to the Council items for inclusion in
the agenda for the next WRC, and to give its views on the preliminary
agenda for the subsequent conference and on possible agenda items for
future conferences, taking into account Resolution **803 (WRC-03)**,

**Background Information:**

The accommodation of unmanned aircraft vehicles or systems (UASs) will
likely have impact on overall aviation spectrum requirements. There is
significant growth forecast in the UAS sector of aviation. Though UASs
have traditionally been used in segregated airspace where separation
from other air traffic can be assured, it is planned to deploy them in
non-segregated airspace. If UASs operate in non-segregated civil
airspace, they must be integrated safely and adhere to the same
operational practices as conventional manned aircraft. To accommodate
such actions, additional safety communication links will be required
(such as AM(R)S and/or aeronautical mobile satellite (R) service
(AMS(R)S)).

Although specific spectrum requirements have yet to be fully assessed,
material has been received regarding UAS integration into non-segregated
civil airspace. Because the pilot is located remotely from the UAS,
bandwidth will be required to support, among other things, each UAS
relaying Air Traffic Control instructions to its respective pilot,
additional operational data, encryption, and interference resilience.

These applications will require additional safety communication links.
While it is expected that short term requirements may be accommodated in
either existing aeronautical bands (e.g. AM(R)S or AMS(R)S) or new
AM(R)S allocations , given the longer term plans for large-scale
deployment of UASs, additional spectrum may be required in the future.

DRAFT RESOLUTION \[UASCOM (WRC-07)\]

**Consideration of spectrum allocations for use by unmanned aircraft
systems (UASs)**

The World Radiocommunication Conference (Geneva, 2007),

considering

*a)* that world-wide use of unmanned aircraft systems (UASs) is expected
to increase significantly in the next 10 years;

*b)* that there is a possible need for additional aeronautical mobile
(R), aeronautical radionavigation, and/or aeronautical mobile-satellite
(R) service spectrum to support the operation of future UASs;

*c)* that there is a need to protect existing services,

further considering

*a)* that UASs represent an application within a radio service such as,
by way of example only, the aeronautical mobile (R) service or the
aeronautical mobile-satellite (R) service;

*b)* that there are emerging UAS applications, including plans to deploy
them in non-segregated airspace alongside conventional manned aircraft
where the UAS must be integrated safely and adhere to the same
operational practices as conventional manned aircraft;

*c)* that future technologies and performance expectations for UASs may
require operations in aeronautical mobile (R), aeronautical
mobile-satellite (R), and/or aeronautical radionavigation service
spectrum to support the transfer of UAS status information to its
control station, transfer flight commands to the UAS from its control
station, and real-time relaying of air traffic control instructions to
and from the UAS operator;

*d)* that studies will be required to provide a basis for considering
regulatory changes, including additional allocations, consistent with
the protection of incumbent services,

*recognizing*

that due to the importance of ensuring the safe operation of UASs in
non-segregated airspace alongside conventional manned aircraft, this
spectrum must be afforded consideration as a safety service according to
No. **4.10** of the Radio Regulations.

resolves

that WRC-11 consider spectrum requirements and possible additional
spectrum allocations for terrestrial and satellite services in the
aeronautical radionavigation, aeronautical mobile (R) and/or
aeronautical mobile-satellite (R) services to support the communications
requirements of UASs;

*further resolves to invite the ITU-R*

1 to conduct, as a matter of urgency, studies to determine the spectrum
requirements and potential frequency bands in the range 108 MHz to 30
GHz suitable to support deployment of UASs in non-segregated airspace.

2 that the studies referred to in *further resolves* 1 should include
sharing and compatibility studies with services already having
allocations in those bands having regard for not constraining the
development of such services.

*further invites*

all members of the Radiocommunications Sector, the International Civil
Aviation Organization (ICAO), and the International Air Transport
Association (IATA) to contribute to these studies.

**Reasons**: This resolution details the scope and required studies
related to future spectrum requirements of unmanned aircraft system
communications links.

**[INFORMAL WORKING GROUP 3 (IWG-3)]{.underline}**

**[IMT-2000 and 2.5 GHz Sharing Issues]{.underline}**

**Document WAC/148(13.12.06):**

**IWG-3 Views A and B on Agenda Item 1.4 (related to 698-806 MHz)**

**WRC-07 Agenda Item 1.4:** To consider frequency-related matters for
the future development of IMT-2000 and systems beyond IMT-2000 taking
into account the results of ITU-R studies in accordance with Resolution
228 (Rev. WRC-03).

**Summary**

Members of IWG-3 considered a proposal under Agenda Item 1.4 that the
698-806 MHz band be allocated to the Mobile Service in all three regions
and be identified for IMT. WRC-07 Agenda Item 1.4 is "To consider
frequency-related matters for the future development of IMT-2000 and
systems beyond IMT-2000 taking into account the results of ITU-R studies
in accordance with Resolution 228 (Rev. WRC-03).

After extensive debate, IWG-3 members were unable to reach agreement on
this issue. Consequently, two views on the identification of 698-806 MHz
with respect to Agenda Item 1.4 were developed. These two documents are
attached as View A and View B.

View A proposes that the 698-806 MHz band be allocated to the Mobile
Service in all three regions and be identified for IMT, the root name
that encompasses both IMT-2000 and IMT-Advanced collectively. View A
states that the identification of the 698-806 MHz band for IMT will
provide administrations with increased flexibility in selecting suitable
frequencies for deployment of advanced wireless technologies. It also
states that such an identification will advance global interests in
promoting the development of advanced wireless services, assist
developing countries in meeting their specific needs, and otherwise meet
the requirements outlined in Resolution 228. View A notes the current
U.S. allocations in this band include new broadcast services, commercial
mobile services, and public safety services.

View A proposes that this identification for IMT be made by adding a
mobile allocation for 698-806 MHz in the ITU Table of Allocations and
adding a footnote to these allocations, Footnote 5.XXX that "The band,
or portions of the band, 698-806 MHz is identified for use by
Administrations wishing to implement International Mobile
Telecommunications (IMT). This identification does not preclude the use
of this band by any application of the services to which they are
allocated and does not establish priority in the Radio Regulations."
View A also proposes modifying the footnotes of bands previously
identified for IMT-2000 to reflect IMT to ensure consistent regulatory
treatment for all bands. View A was supported by Alcatel-Lucent, CDMA
Development Group, Cingular, Ericsson, Lockheed Martin, Nokia, Qualcomm,
TMG, and Verizon.

View B also proposes to add a global mobile allocation to the 698-806
MHz band, and proposes to identify the band for IMT and other broadband
wireless access systems. Proponents of View B felt that the US needed to
more broadly address the agenda item, including modification of the
existing IMT-2000 footnotes, in the proposal. Proponents of View B felt
that its approach to spectrum identification is flexible and will allow
current operators and new licensees in the identified frequency bands to
bring advanced services to consumers as rapidly as new technology
allows. . View B also proposes to modify all the existing IMT-2000
footnotes in a similar fashion, and to provide the necessary updates to
the Resolutions associated with these footnotes (Resolutions 212, 223
and 224). With respect to the 698-806 MHz band, View B adds provisions
to Resolution 224 to recognize that portions of the band are also used
for public protection & disaster relief in some regions, as well as
other services such as broadcasting. View B was supported by ArrayComm,
Clearwire, Henry Straube, Intel, Motorola, Nortel, Sprint Nextel, and
the Wireless Communications Association International, Inc.

IWG-3 respectfully submits the two views to the WRC Advisory Committee
for consideration.

***[View A]{.underline}***

**DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE**

**Agenda Item 1.4:** to consider frequency-related matters for the
future development of IMT-2000 and systems beyond IMT-2000 taking into
account the results of the ITU-R studies in accordance with Resolution
228 (Rev. WRC-03);

**Background:** WRC-2000 invited the ITU-R in Resolution 228 to continue
studies on overall objectives, applications and technical and
operational implementation for the future development of IMT-2000 and
systems beyond IMT-2000. It also invited the ITU-R to study spectrum
requirements and potential frequency ranges suitable for the future
development of IMT-2000 and systems beyond IMT-2000, and to determine
what time frame such spectrum would be needed. Resolution 228 (WRC-2000)
also resolved that the requirements for the future development of
IMT-2000 and systems beyond IMT-2000 are to be reviewed by WRC-07,
taking into consideration the results of ITU-R studies presented to
WRC-03. However, those studies were not completed in time for WRC-03.

WRC-03 revised Resolution 228 (Rev.WRC-03), inviting the ITU-R to
further study the technical and operational issues relating to the
future development of IMT-2000 and systems beyond IMT-2000 and to
develop reports and recommendations as required in time for WRC-07. In
particular, Resolution 228 (Rev. WRC-03) invites the ITU-R to report on
the results of studies on the spectrum requirements and potential
frequency ranges suitable for the future development of IMT-2000 and
systems beyond IMT-2000, taking into account a variety of factors
including the growth in demand for IMT-2000 services, the evolution of
systems through advances in technology, the time-frame in which spectrum
will be needed, and the extensive use of frequencies below those already
identified for IMT-2000, i.e., below 806 MHz. It invites the ITU-R to
conduct studies on the potential use of such frequencies for the future
development of IMT-2000 and systems beyond IMT-2000, assessing whether
their use could satisfy the needs of developing countries and countries
with large areas of low-population density for more cost-effective
alternatives when implementing IMT-2000 systems and systems beyond
IMT-2000. Resolution 228 (Rev. WRC-03) requests that such studies
consider the results of sharing and compatibility studies with services
to which these bands have already been allocated.

Resolution 228 (Rev.WRC-03) also notes that the ITU-R has already begun
considering appropriate naming for the future development of IMT-2000
and systems beyond IMT-2000 for a decision in advance of WRC-07. With
that in mind, Study Group 8 has developed a new Draft Resolution ITU-R
M.\[IMT.NAME\], "Naming for International Mobile Telecommunications,"
for consideration by the Radiocommunication Assembly 2007. This Draft
Resolution specifies the nomenclature for the future development of
IMT-2000 and systems beyond IMT‑2000 through names uniquely associated
with the advancement and continuation of International Mobile
Telecommunications (IMT). In particular, it resolves that the term
"IMT-2000" encompasses also its enhancements and future developments and
that the new name "IMT-Advanced" be applied to those systems, system
components, and related aspects that include new radio interface(s) that
support the new capabilities of systems beyond IMT-2000. It also
resolves that the term "IMT" be the root name that encompasses both
IMT-2000 and IMT-Advanced collectively.

**Spectrum Below 806 MHz:** Some Administrations have already taken
steps to enable IMT-2000 systems to be implemented in bands below those
currently identified, i.e., below 806 MHz. Due to the favorable
propagation characteristics of lower frequencies, there are significant
coverage benefits and resulting reductions in equipment requirements
associated with deploying advanced wireless systems in the 698-806 MHz
band, especially in areas with low population densities. These benefits
are important considerations for developing countries, which may have
spectrum available but not have resources to deploy nationwide systems
in the higher frequency ranges identified by the ITU for IMT.

Currently, the 698-806 MHz band is used throughout most of the world for
Broadcasting Services. These services are experiencing significant
changes coincident with the rapid introduction of new technologies. For
example, the application of digital technologies to broadcast television
has resulted in significant benefits to consumers including clearer,
sharper pictures, higher quality sound, enhanced features such as access
to information services, and the ability to integrate televisions with
computers and other digital devices. These advancements parallel the
significant innovations occurring within the mobile equipment and
services market, and have resulted in the availability of enhanced video
and audio services on mobile phones, laptop computers, and numerous
other portable digital devices.

The use of digital technology for Broadcasting Services also
substantially improves the manner in which the radio frequency spectrum
is used. Digital compression substantially improves spectral efficiency,
enabling more services to be supported on less spectrum. As a result,
Administrations planning to transition existing Broadcasting Services to
digital technology may wish to make some, or all, of the spectrum
available for other uses, including advanced wireless technologies like
IMT.

In the United States, for example, existing broadcast television
services will be cleared from the 698-806 MHz band by February 17, 2009,
as part of a comprehensive plan to transition to the use of digital
technology. This transition will enable the spectrum to be freed up for
other uses, including new broadcast services, commercial mobile
services, and public safety services, consistent with current
allocations. Some commercial licenses have already been assigned, while
all remaining commercial licenses are required to be auctioned no later
than January 28, 2008. Commercial deployments are expected to include
advanced mobile technologies like IMT-2000, as well as advanced
broadcasting technologies that will deliver multimedia content to
handsets and other mobile devices.

Recognizing that Administrations are free to use the band for whatever
purpose best suits their individual needs, including commercial and
non-commercial applications, the identification of the 698-806 MHz band
for International Mobile Telecommunications (IMT) will provide
administrations with increased flexibility in selecting suitable
frequencies for deployment of advanced wireless technologies. Taking
into account the benefits of utilizing lower frequency bands in areas of
less dense population, developing countries at WRC-03 specifically
requested that bands below 806 MHz be considered for identification at
WRC-07. This request was directed to all members of the ITU, both
developed and developing countries.

**Proposal:** Resolution 228 (Rev. WRC-03) resolves that the ITU-R
conduct studies on the spectrum requirements and potential frequency
ranges suitable for IMT, including frequencies below those previously
identified (i.e., below 806 MHz). These studies, which include sharing
and compatibility studies with services already having allocations in
those frequency bands, are already being undertaken. Consistent with
Resolution 228 (Rev. WRC-03) and recognizing the needs of developing
countries, the United States proposes that the 698-806 MHz band be
allocated to the Mobile Service in all three regions and be identified
for IMT. Such an identification will advance global interests in
promoting the development of advanced wireless services, assist
developing countries in meeting their specific needs, and otherwise meet
the requirements outlined in Resolution 228.

Identification of the 698-806 MHz band for "IMT," rather than "IMT-2000"
which has been the case for spectrum identified at previous WRCs, will
ensure that it is identified in a manner consistent with new Draft
Resolution ITU-R M.\[IMT.NAME\], and thus, will encompass the future
development of IMT-2000 as well as systems beyond IMT-2000. The United
States also proposes modifying the footnotes of bands previously
identified for IMT-2000 to reflect IMT. This will ensure that all bands
have consistent regulatory treatment. Conforming amendments should be
made to Resolutions 212, 223, and 224 to reflect the new naming
convention.

account the results of the ITU-R studies in accordance with Resolution
228 (Rev. WRC-03);

**Background:** WARC-92 identified the 1885-2025 MHz and 2110-2200 MHz
bands for possible use on a worldwide basis by administrations wishing
to implement IMT-2000 systems in footnote No. **5.388**. Subsequently,
WRC-2000 identified the 806-960 MHz band in footnote No. **5.317A** and
the 1710-1885 MHz and 2500-2690 MHz bands in footnote No. **5.384A** for
possible IMT-2000 use.

The identification of multiple bands for IMT-2000 use reflects the
national and regional differences that exist in the use of the radio
spectrum. With identification of additional spectrum expected at
upcoming WRCs for IMT-2000 and systems beyond IMT-2000, Administrations
are likely to continue to utilize various subsets of the identified
frequency bands to meet national, regional and international user
demands.

There have been advances in a range of wireless technologies such that
it is now prudent to review the current identifications of spectrum for
IMT-2000. Technology is not static. IMT-2000 technologies will continue
to evolve and comparable or more advanced technologies will be
introduced. Some administrations may wish to implement comparable
advanced wireless technologies in the current IMT-2000 bands and any
other bands identified by WRC-07 that are not currently part of the
IMT-2000 family. For example, in the 2500-2690 MHz band in the United
States, service providers have chosen to deploy other broadband wireless
access technologies that are not part of IMT-2000. These technologies
may eventually become part of "systems beyond IMT-2000", but, as
described further in the following paragraphs, at this time the ITU-R is
still in the process of defining the systems/technologies that will make
up IMT-Advanced/systems beyond IMT-2000. It is expected that the WRC
could provide clarification in this regard.

Furthermore, the United States believes that it is essential not to tie
specific technologies to specific frequency bands. In keeping with its
technology-neutral belief that existing mobile operators should be free
to evolve to IMT-2000 and other advanced wireless systems as the market
demands, the United States proposes a flexible approach to spectrum
identification, to allow current operators and new licensees in the
identified frequency bands to bring advanced services to consumers as
rapidly as new technology allows. This approach has the advantage of not
artificially tying the rollout of new technology and services to new
spectrum as administrations assess their ability to use that spectrum
for IMT-2000 and other advanced wireless systems.

[Terminology.]{.underline} Draft Resolution ITU-R M.\[IMT-NAME\]
identifies a root name, IMT, to cover the capabilities of "IMT-2000,
future development of IMT-2000 and systems beyond IMT-2000."  It also
clarifies that IMT-2000 also encompasses its enhancements and future
developments.  The draft Resolution identifies a new name, IMT-Advanced,
to cover systems beyond IMT-2000.

[IMT-Advanced.]{.underline} IMT-Advanced is currently being studied
within the ITU-R. The ITU-R has prepared draft new Resolution
M.\[Principles\] that establishes principles for the process of
development of IMT-Advanced.   The document sets out that
Recommendations and Reports will be developed for IMT-Advanced,
including Recommendation(s) for radio interface specifications. In
addition, Recommendation ITU-R M.1645 contains the framework for
IMT-Advanced's development and its overall objectives, and also
describes the minimum technical requirements for IMT-Advanced.

The current ITU-R timeline for IMT-Advanced is to determine the radio
interface technologies that make up IMT-Advanced around the year 2010,
with the expectation that systems will be deployed around the year 2015.
However, draft Resolution ITU-R M.\[IMT-NAME\] recognizes that wireless
access technologies that may address some of the capabilities of systems
beyond IMT-2000 have been or are being developed for deployment within
or prior to the timeframes expressed in Recommendation ITU-R M.1645. The
reality is that systems that meet the new capabilities for IMT-Advanced
will have entered the market well prior to 2010 and have already been
recommended by the ITU, such as the broadband wireless access systems in
Recommendations ITU-R M.\[8A-BWA\] and ITU-R F.1763.

[Resolution **228**.]{.underline} WRC-03 revised Resolution **228
(Rev.WRC-03)**, inviting the ITU-R to further study the technical and
operational issues relating to the future development of IMT-2000 and
systems beyond IMT-2000 and to develop reports and recommendations as
required in time for WRC-07. In particular, Resolution **228 (Rev.
WRC-03)** invites the ITU-R to report on the results of studies on the
spectrum requirements and potential frequency ranges suitable for the
future development of IMT-2000 and systems beyond IMT-2000, taking into
account a variety of factors including the growth in demand for IMT-2000
services, the evolution of systems through advances in technology, and
the extensive use of frequencies below those identified for IMT-2000 in
No. **5.317A**. It invites the ITU-R to conduct studies on the potential
use of such frequencies for the future development of IMT-2000,
assessing whether their use could satisfy the needs of developing
countries and countries with large areas of low-population density for
more cost-effective alternatives when implementing IMT-2000 systems.
Resolution **228 (Rev. WRC-03)** requests that such studies consider the
results of sharing and compatibility studies with services to which
these bands have already been allocated.

[Additional spectrum.]{.underline} Currently, the 698-806 MHz band is
used throughout most of the world for Broadcasting Services. These
services are experiencing significant changes coincident with the rapid
introduction of new digital technologies. The use of digital technology
for Broadcasting Services substantially improves the manner in which the
radio frequency spectrum is used. Digital compression substantially
improves spectral efficiency, enabling more services to be supported on
less spectrum. As a result, Administrations planning to transition
existing Broadcasting Services to digital technology may wish to make
some, or all, of the spectrum available for other uses, including
advanced wireless technologies like IMT-2000 and systems beyond
IMT-2000. Due to the favorable propagation characteristics of lower
frequencies, there are significant coverage benefits and cost
efficiencies associated with deploying advanced wireless systems in the
698-806 MHz band, especially in areas with low population densities.
These benefits are important considerations for developing countries,
which may have spectrum available but not have resources to deploy
nationwide systems in the higher frequency ranges identified by the ITU
for IMT-2000.

In the United States, for example, existing broadcast television
services will be cleared from the 698-806 MHz band by February 17, 2009,
as part of a comprehensive plan to transition to the use of digital
technology. This transition will enable the spectrum to be freed up for
other uses, including new broadcast services, commercial mobile
services, and public safety services, consistent with current
allocations. The United States reallocated 84 MHz for commercial
wireless services and 24 MHz for public safety services. Some commercial
licenses have already been assigned, while all remaining commercial
licenses are required to be auctioned no later than January 28, 2008.
Commercial deployments are expected to include advanced mobile
technologies like IMT-2000, as well as advanced broadcasting
technologies that will deliver multimedia content to handsets and other
mobile devices. Public safety systems are also under development in the
24 MHz of spectrum designated for public safety services, and will use
this spectrum for narrowband, wideband and broadband communications
requirements. These uses are consistent with Resolution **646
(WRC-03)**, which encourages administrations in Region 2 to use common
frequency bands for public protection and disaster relief and to
consider the use of the band 746-806 MHz, among others. In addition, it
also states that some countries in Region 3 have identified the 746-806
MHz band for public protection and disaster relief applications.

Recognizing that Administrations are free to use the band for whatever
purpose best suits their individual needs, including commercial and
non-commercial applications, the identification of the 698-806 MHz band
for IMT will provide administrations with increased flexibility in
selecting suitable frequencies for deployment of advanced wireless
technologies. Taking into account the benefits of utilizing lower
frequency bands in areas of less dense population, developing countries
at WRC-03 specifically requested that bands below 806 MHz be considered
for identification at WRC-07. This request was directed to all members
of the ITU, both developed and developing countries.

**Proposal:** Consistent with Resolution **228 (Rev. WRC-03)** and
recognizing the needs of developing countries as well as the continued
development of advanced wireless technologies, the United States
proposes that the 698-806 MHz band be identified for IMT and other
broadband wireless systems in accordance with a revised Resolution 224.
IMT is the root name which includes both IMT-2000 and systems beyond
IMT-2000. Such an identification will advance global interests in
promoting the development of advanced wireless services based on a
flexible framework that accommodates a broad base of comparable wireless
technologies, assist developing countries in meeting their specific
needs, and otherwise meet the requirements outlined in Resolution 228.
This proposal also contains the proposed revisions to Resolution 224,
which addresses spectrum for IMT below 1 GHz.

In addition, the United States proposes that the current footnotes
identifying spectrum for IMT-2000 (Nos. 5.517A, 5.384A & 5.388) be
revised to refer to IMT and other broadband wireless systems. This will
facilitate implementation of IMT-2000, systems beyond IMT-2000 and other
broadband wireless access systems by providing clear guidance on the use
of these frequency bands for these advanced communications applications.
Corresponding modifications are required to the Resolutions associated
with these footnotes---Resolution 212, Resolution 223 and Resolution
224.

**Document WAC/149(13.12.06):**

**Views A and B on Agenda Item 1.4 (related to 3650-3700 MHz)**

**WRC-07 Agenda Item 1.4:** To consider frequency-related matters for
the future development of IMT-2000 and systems beyond IMT-2000 taking
into account the results of ITU-R studies in accordance with Resolution
228 (Rev. WRC-03).

**Summary**

At the request of the WAC, members of IWG-2 and IWG-3 met within IWG-3
to jointly consider how to treat the band 3650-3700 MHz as it relates to
WRC-07 Agenda Item 1.4 which is "To consider frequency-related matters
for the future development of IMT-2000 and systems beyond IMT-2000
taking into account the results of ITU-R studies in accordance with
Resolution 228 (Rev. WRC-03).

After extensive debate, IWG-3 members were unable to reach agreement on
this issue. Consequently, two views on the treatment of 3650-3700 MHz
with respect to Agenda Item 1.4 were developed. These two documents are
attached as View A and View B.

View A proposes no change to the Table of Frequency Allocations of the
Radio Regulations with regard to the 3650 -- 3700 MHz band. View A
states that such a proposal is consistent with the results of the ITU-R
studies to date have shown that sharing of the 3650 -- 3700 MHz band by
IMT-Advanced systems and the fixed satellite service is not feasible in
the same geographic area. View A also states that there are significant
FSS assets on the 3650 -- 3700 MHz around the world, including a
significant number of space networks registered by the United States
that utilize this band, that would be severely impacted by the
identification of this band under WRC-07 agenda item 1.4. View A was
supported by Boeing, Intelsat, the Global VSAT Forum; Northrop Grumman
Corporation and the Satellite Industry Association (SIA - whose members
also include Arrowhead Global Solutions, Inc.; Artel, Inc.; ATK, Inc.;
The DirecTV Group; EMC, Inc.; Eutelsat, Inc.; Globalstar, LLC; Hughes
Network Systems, LLC; ICO Global communications; Inmarsat, Inc.;
Integral Systems, Inc.; IOT Systems; Iridium Satellite LLC; Lockheed
Martin Corp.; Loral Space & Communications Inc.; Loral Skynet ; Marshall
Communications Corp.; Mobile Satellite Ventures LP; SES-New Skies, Inc.;
SES-Americom, Inc.; Spacecom Corp.; Spacenet, Inc.; Stratos Global Corp.
and TerreStar Networks, Inc.).

View B proposes that the US have no proposal of no change to 3650-3700
MHz under Agenda Item 1.4. View B states that unlike the satellite
operations in the US above 3700 MHz, which is much more heavily used
with satellites at approximately 2 degree spacing across the domestic
arc and the corresponding higher number of associated earth stations,
the United States does not believe that the limited number of satellites
and earth stations below 3700 MHz present the same sharing concerns and
therefore do not justify a no change proposal from the United States.
Further, View B states that it would send the wrong message
internationally, especially as the United States decided to limit
satellite use in the band in order to facilitate broader terrestrial
use. View B states that, however, given the type of terrestrial use in
the US (e.g., low EIRP limits), the United States does not propose the
identification of the 3650-3700 MHz band under agenda item 1.4 at this
time. View B was supported by Intel, Motorola, Nokia, Sprint Nextel, and
the Wireless Communications Association International, Inc.

IWG-3 respectfully submits the two views to the WRC Advisory Committee
for consideration.

**DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE**

**WRC-07 Agenda Item 1.4:** To consider frequency-related matters for
the future development of IMT-2000 and systems beyond IMT-2000 taking
into account the results of ITU-R studies in accordance with Resolution
**228 (Rev. WRC-03)**.

**Background**

The RCS had previously proposed in IWG-3/WRC-07/Proposal/Background/Doc.
4 that the ITU Table of Frequency Allocations not be changed in the
frequency band 3400 -- 4200 MHz, citing that ITU-R studies had not shown
compatibility between IMT systems and the radiolocation service, nor
between IMT systems and the fixed or fixed satellite service. The
Satellite Industry Association ("SIA") proposed in
IWG-3/WRC-07/Proposal/Doc. 15 that the ITU Table of Frequency
Allocations not be changed in the frequency band 3400 -- 4200 MHz citing
that ITU-R studies had shown that sharing between IMT systems and the
fixed satellite service was not feasible within the same geographic
area.

After discussion within IWG-3, the SIA document was subsequently
modified such that it proposed no change to the ITU Table of Frequency
Allocation only in the 3700 -- 4200 MHz band (see WAC/135(04.10.06) and
FCC Public Notice DA 06-2013, October 12, 2006). The RCS document was
modified so that it proposed no change to the ITU Table of Frequency
Allocation only to the frequency band 3400 -- 3650 MHz.

The modified RCS document was subsequently submitted to and reviewed by
IWG-2 (see document IWG-2/067). After consideration of this document,
IWG-2 felt that the "no change" should be extended to the entire 3400 --
4200 MHz band, and not limited to the 3400 -- 3650 MHz band. IWG-2
emphasized the extreme significance of the 3650 -- 4200 MHz band for the
FSS industry. IWG-2 comments were submitted to IWG-3 for further
consideration of this matter (see IWG-3/WRC-07/Background/Doc. 7).

With regard to the 3650 -- 3700 MHz band, IWG-3 had indicated that "no
change" status as originally proposed by RCS (and also by SIA) should
not be applied to this band and opposed adding sharing issues with the
fixed satellite service ("FSS"). IWG-3 indicated that although the 3700
-- 4200 MHz band was extensively used by FSS in the United States; this
was not the case in the band below 3700, as the density of FSS earth
station deployment is much lower. In the United States, the 3650 -- 3700
MHz band is allocated to the fixed and mobile terrestrial services and
FSS use is limited to certain grandfathered sites. Further, the use of
the 3600 -- 3650 MHz band by the FCC is limited to international,
inter-continental systems. IWG-3's comments are contained in document
IWG-3/WRC-07/Proposal/Doc.17r2.

IWG-3 is aware that ITU-R Working Party 8F ('WP8F") has conducted a
number of technical studies pertaining to sharing of the 3400 -- 4200
MHz band by FSS and systems beyond IMT-2000 (hereafter referred to as
"IMT-Advanced"). WP8F has indicated that some physical separation
between and FSS receive earth station and the IMT-Advanced transmitter
would be required. Based upon the results of the sharing studies
conducted by WP8F and the allocation/use of the 3400 -- 4200 MHz band
within the United States, the administration of the United States has
supported within WP8F the position that sharing between IMT-Advanced and
FSS in the 3600 -- 4200 MHz band is not feasible in the same geographic
area (see ITU-R Document 8F/947).

In the course of further discussions of this issue by IWG-3, FSS
representatives emphasized that frequencies below 3700 MHz, especially
the band 3625-3700 MHz, had significant use in other areas of the world,
i.e. outside of the United States. For example one global FSS operator,
Intelsat, operates 14 U.S. licensed satellites that utilize the 3625 --
3700 MHz band. These satellites cumulatively provide an equivalent of
124, 36-MHz transponders in this band. This is, in turn, equivalent to
approximately five satellites, with each carrying 24 standard 36-MHz
transponders. The signals from these channels are received by over 1100
receive stations worldwide. In addition to Intelsat, several other
satellite operators have significant investments in spacecraft with
payloads that include the band 3625 -- 3700 MHz with large number of
customers using these frequencies worldwide. The identification of the
3650 -- 3700 MHz band as a candidate for identification for IMT-Advanced
systems would encourage the introduction of terrestrial systems that are
not compatible with extensive FSS operations and would affect the
significant investments already made by FSS operators and users.

IWG-3 notes that the decision to use the 3650 -- 3700 MHz band for
terrestrial services can continue on a country-by-country basis as is
currently happening. However, given the mixed allocation environment
that is currently prevalent worldwide with respect to the 3400 -- 4200
MHz and the extensive use of this by U.S. registered space stations (and
their associated receive earth stations worldwide) the identification of
the 3650 -- 3700 MHz band on a worldwide basis does not seem to be
feasible or appropriate.

**Proposal**

No change to the table of Frequency Allocations of the Radio Regulations
with regard to the 3650 -- 3700 MHz band.

**Reasons**

Results of the ITU-R studies to date have shown that sharing of the 3650
-- 3700 MHz band by IMT-Advanced systems and the fixed satellite service
is not feasible in the same geographic area. This band may be used for
terrestrial services (e.g. BWA) on a country-by-country basis. However,
there are significant FSS assets on the 3650 -- 3700 MHz around the
world, including a significant number of space networks registered by
the United States that utilize this band, that would be severely
impacted by the identification of this band under WRC-07 agenda item
1.4.

***[View B]{.underline}***

**DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE**

**WRC-07 Agenda Item 1.4:** To consider frequency-related matters for
the future development of IMT-2000 and systems beyond IMT-2000 taking
into account the results of ITU-R studies in accordance with Resolution
**228 (Rev. WRC-03)**.

**Background:**

Document IWG-3/WRC-07/Proposal/Doc. 20 proposes no change to the
International Table of Frequency Allocations in the band 3650-3700 MHz,
because of the potential for interference to satellite downlinks
deployed in the same geographic area.

In the United States, fixed and mobile terrestrial services are
allocated on a primary basis in 3650-3700 MHz and the FCC adopted
service rules to govern the terrestrial operations with the intent of
stimulating the rapid expansion of broadband wireless services. When
adopting the terrestrial allocations, the FCC limited the FSS use to
certain grandfathered sites[^5] in order to ensure availability of the
band for terrestrial services. Further, use of the FSS allocation is
limited to international/inter-continental systems.

Any US proposal for no change to expand terrestrial use of the band
internationally because of concerns with interference to or constraining
satellite use would be inconsistent with domestic use of the band, and
would disenfranchise domestic terrestrial users from the benefits of a
potential global market. It would send the wrong message
internationally, especially as the United States decided to limit
satellite use in the band in order to facilitate broader terrestrial
use. Unlike the satellite operations in the United States above 3700
MHz, which is much more heavily used with satellites at approximately 2
degree spacing across the domestic arc and the corresponding higher
number of associated earth stations, the United States does not believe
that the limited number of satellites and earth stations below 3700 MHz
present the same sharing concerns and therefore do not justify a no
change proposal from the United States. Further, it is common US policy
to promote international use that is harmonized with its domestic use.
US service providers who use the 3650-3700 MHz band and manufacturers
who build equipment for the band would benefit from harmonized use
outside of the United States, as economies of scale would result in
lower equipment costs which could also be passed on to US consumers.

However, given the type of terrestrial use in the US (e.g., low EIRP
limits), the United States does not propose the identification of the
3650-3700 MHz band under agenda item 1.4.

**Proposal:**

Considering the above perspectives, the United States has decided not to
have a proposal under agenda item 1.4 on 3650-3700 MHz.

**Reason:** Unlike the satellite operations in the US above 3700 MHz,
which is much more heavily used with satellites at approximately 2
degree spacing across the domestic arc and the corresponding higher
number of associated earth stations, the United States does not believe
that the limited number of satellites and earth stations below 3700 MHz
present the same sharing concerns and therefore do not justify a no
change proposal from the United States. Further, it would send the wrong
message internationally, especially as the United States decided to
limit satellite use in the band in order to facilitate broader
terrestrial use. However, given the type of terrestrial use in the US
(e.g., low EIRP limits), the United States does not propose the
identification of the 3650-3700 MHz band under agenda item 1.4.

**Informational Report**

**To WRC-07 Advisory Committee**

**Regarding an AM(R)S allocation in the 5 to 6 GHz Band**

**Agenda Item 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).**

The CPM text for Agenda Item 1.6 was developed by Working Party 8B after
liaison with Working Party 8D. This text reflects the possibility of
using the 5000-5010 MHz and 5010-5030 MHz bands currently allocated to
the aeronautical radionavigation service (ARNS), aeronautical mobile
satellite (R) service (AMS(R)S) and Radionavigation Satellite Service
(RNSS) to provide for AM(R)S under the provision that the AM(R)S could
not cause harmful interference to, nor claim protection from, nor
constrain the development of the RNSS.

In response, the U.S. GPS Industry Council, on behalf of the U.S. RNSS
private industry and users of RNSS services (including the U.S. GPS
system) presented a proposal to IWG-4 that the U.S. propose to WRC '07
that there be no change to the Table of Allocations in the frequency
bands 5000-5010 MHz and 5010-5030 MHz. This proposal was opposed by ASRI
(Aviation Spectrum Resources, Inc.) on behalf of the civil aviation
community, citing the existing congestion of AM(R)S spectrum, and recent
International Civil Aviation Organization (ICAO) studies pointing to a
need for up to 100 MHz of new spectrum to support civil aviation airport
surface communications.

Given the new nature of the RNSS allocation at WRC-03, the U.S. RNSS
industry has not yet had the opportunity to develop applications for its
use. However, industry envisions the possibility of its use for both
RNSS service and feeder-link applications, and would not want to have
these possible applications foreclosed by a new additional allocation in
these bands. Consequently, the RNSS industry is opposed to the use of
the aforementioned RNSS bands for any other service if interference
cannot be prevented by the new service or if constraints on use of the
band for RNSS are reasonably expected to result from the new service.

The aviation community pointed to ITU-R studies and the recent
introduction of RNSS into the heavily used 1164-1215 MHz band (e.g., GPS
L5) as models demonstrating the feasibility of achieving compatibility
between RNSS and AM(R)S. Civil aviation indicated it believes that
sharing between RNSS and AM(R)S is feasible and further noted that any
RNSS applications for those bands are far-term at best (e.g., the only
mention in the current GPS III specification is for a possible future
5010-5030 MHz feeder link), and leaving the band fallow could set a bad
precedent from a spectrum efficiency perspective.

IWG-4 considered the proposal suggested by the U.S. RNSS industry and
the comments of the civil aviation community and was not able to reach
consensus. Nonetheless, IWG-4 wishes to have the Report of WAC-'07 note
the suggestions of both the U.S. RNSS industry and the US aviation
community for consideration by the U.S. Government as it develops U.S.
proposals to WRC '07.

**DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE**

**Agenda Item 7.2:** to recommend to the Council items for inclusion in
the agenda for the next WRC, and to give its views on the preliminary
agenda for the subsequent conference and on possible agenda items for
future conferences, taking into account Resolution **803 (WRC-03)**,

**Background Information:** At WRC-03, Agenda Item 1.6 for the 2007
Conference was adopted to, in part, "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)**."
Studies in support of that agenda item concluded that:

> "The accommodation of unmanned aerial vehicles (UAVs) will likely have
> impact on overall aviation spectrum requirements. There is significant
> growth forecast in the UAV sector of aviation. Though UAVs have
> traditionally been used in segregated airspace where separation from
> other air traffic can be assured, it is planned to deploy them in
> non-segregated airspace. If they operate in non-segregated civil
> airspace, they must be integrated safely and adhere to the same
> operational practices as conventional manned aircraft. To accommodate
> such actions, additional safety communication links will be required
> (AM(R)S and/or aeronautical mobile satellite (R) service (AMS(R)S))";
> and
>
> "Although specific spectrum requirements have yet to be fully
> assessed, material has been received regarding UAV integration into
> non-segregated civil airspace. Because the pilot is located remotely
> from the UAV, bandwidth will be required to support, among other
> things, each UAV relaying ATC instructions to its respective pilot,
> additional operational data, encryption, and interference resilience.
> These applications will require additional safety communication links.
> While it is expected that short term requirements may be accommodated
> in either existing aeronautical bands (AM(R)S or AMS(R)S) or the new
> AM(R)S allocations made under this agenda item, given the longer term
> plans for large-scale deployment of UAVs, additional spectrum may be
> required in the future."

vehicles (UAVs)**

The World Radiocommunication Conference (Geneva, 2007),

considering

*a)* that world wide use of unmanned aerial vehicles (UAVs) is expected
to increase significantly in the next 10 years;

*b)* that there is a possible need for additional aeronautical mobile
and/or aeronautical mobile-satellite service spectrum to support the
operation of future UAVs;

*c)* that there is a need to protect existing services,

recognizing

*a)* that there are emerging UAV applications, including plans to deploy
them in non-segregated airspace alongside conventional manned aircraft
where the UAV must be integrated safely and adhere to the same
operational practices as conventional manned aircraft;

*b)* that future technologies and performance expectations for UAVs will
require the use of spectrum to support the transfer of UAV status
information to its control station, transfer flight commands to the UAV
from its control station, and real-time relaying of air traffic control
instructions to and from the UAV operator;

*c)* that due to the importance of ensuring the safe operation of UAVs
in non-segregated airspace along side conventional manned aircraft, this
spectrum must be afforded special consideration as a safety service
according to No. **4.10** of the Radio Regulations (RR);

*d)* that studies will be required to provide a basis for considering
regulatory changes, including additional allocations, to accommodate
spectrum requirements of UAVs consistent with the protection of
incumbent services,

resolves

that WRC-10 consider spectrum requirements and possible additional
spectrum allocations for terrestrial and satellite services in the
aeronautical mobile and aeronautical mobile-satellite services to
support the communications requirements of UAVs;

*further resolves to invite the ITU-R*

1 to conduct, as a matter of urgency, studies to determine the spectrum
requirements and potential frequency bands suitable to support
deployment of UAVs;

2 that the studies referred to in *further resolves* 1 should include
sharing and compatibility studies with services already having
allocations in those bands,

*further invites*

all members of the Radiocommunications Sector and the International
Civil Aviation Organization (ICAO) to contribute to these studies.

**Reasons**: This resolution details the scope and required studies
related to future spectrum requirements of unmanned aerial vehicles
communications links.

    January 2004 to assist the FCC in developing proposals for WRC-07.
    Since its inception, the WRC-07 Advisory Committee has developed and
    submitted recommendations and preliminary views for Commission
    consideration. *See, e.g., The FCC's Advisory Committee for the 2007

    WRC-03.

[^5]: Although there are only 49 grandfathered sites, BWA transmitters
    must be coordinated within a 150 km radius around each of these
    sites. Many of the grandfathered sites are in close proximity,
    resulting in a significant overlap of the 150 km coordination zones
    (see Attachment 1)
