**THE FCC\'S ADVISORY COMMITTEE FOR THE**

**2003 WORLD RADIOCOMMUNICATION CONFERENCE APPROVES**

**DRAFT PROPOSALS**

On September 5, 2002, the World Radiocommunication Conference Advisory
Committee (WRC-03 Advisory Committee) adopted recommendations to the
Commission on numerous issues that the 2003 World Radiocommunication
Conference (WRC-03) will address. The WRC-03 Advisory Committee was
established by the Commission in January 2001 to assist it in the
development of proposals for WRC-03. To that end, the WRC-03 Advisory
Committee has forwarded the recommendations it has developed since the
beginning of 2001 to the Commission for consideration. We have attached
to this Public Notice the WRC-03 Advisory Committee's recommendations,
which are in the form of recommended draft proposals to the WRC-03. We
appreciate the substantial amount of work that the WRC-03 Advisory
Committee has put into developing its recommendations. This Public
Notice requests comments on all of these recommendations.

Based upon our initial review of the recommendations forwarded to the
Commission, the International Bureau, in coordination with other
Commission Bureaus and Offices, tentatively concludes that we can
generally support all of the proposals recommended by the WRC-03
Advisory Committee. We do, however, have some reservations about the
proposals reflected in documents WAC/144, WAC/146 and WAC/147. We also
take note of differing views expressed by WRC-03 Advisory Committee
participants in document WAC/144. We seek comment on the recommendations
that appear in all of the WRC-03 Advisory Committee documents and on our
tentative conclusions.

In addition, the National Telecommunications and Information
Administration (NTIA) has submitted letters to the Commission containing
draft proposals that have been developed by the Executive Branch
Agencies. We also request comment on these draft proposals, which are
attached hereto as well.

The FCC will consider the draft proposals and comments provided in its
upcoming consultations with the U.S. Department of State and NTIA in the
development of U.S. proposals to WRC-03. Once agreed by these agencies
of the U.S. Government, proposals will be used by U.S. delegations at
bilateral, regional and international meetings. The draft proposals
attached to this Public Notice may evolve as we approach WRC-03 and
during the course of interagency discussions. Therefore, they do not
constitute the final national position on these issues.

The complete texts of these draft proposals are also available in the
FCC\'s Reference Information Center, Room CY-A257, 445 12th Street, SW,
Washington, DC 20554 and by accessing the FCC\'s WRC-03 world wide web
site at http://www.fcc.gov/wrc-03. To comment on the proposals, please
submit an original and one copy of your comments to the Office of the
Secretary, Federal Communications Commission, 445 12th Street, SW,
Washington, DC 20554 and provide a courtesy copy to Alex Roytblat, FCC
WRC-03 Director, Room 6-A738. Comments should refer to specific
proposals by document number. The deadline for comments on the draft
proposals and NTIA letters is **October 18, 2002**.

Interactive Media**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/139(05.09.02)

**WRC-03 Agenda Item 1.21**: to consider progress of the ITU‑R studies
concerning the technical and regulatory requirements of terrestrial
wireless interactive multimedia applications, in accordance with
Resolution **737 (WRC-2000)**, with a view to facilitating global
harmonization;

# Background Information: At WRC-2000, a proposal from several European administrations indicated a desire to address spectrum for terrestrial wireless interactive multimedia applications. After much discussion, WRC-2000 adopted Resolution 737, which invites the ITU-R to pursue studies to facilitate the development of common, worldwide spectrum allocations or identifications suitable for new terrestrial wireless interactive multimedia (TWIM) technologies and applications; review the regulatory methods and appropriate means to facilitate the worldwide harmonization of spectrum for terrestrial wireless interactive multimedia, and to review service definitions in the light of convergence of applications, if necessary. In addition, WRC-2000 adopted agenda item 1.21 so that WRC-2003 could review the progress of these studies and agenda item 2.15 for WRC-2005/6 to discuss the spectrum and regulatory issues associated with TWIM applications. {#background-information-at-wrc-2000-a-proposal-from-several-european-administrations-indicated-a-desire-to-address-spectrum-for-terrestrial-wireless-interactive-multimedia-applications.-after-much-discussion-wrc-2000-adopted-resolution-737-which-invites-the-itu-r-to-pursue-studies-to-facilitate-the-development-of-common-worldwide-spectrum-allocations-or-identifications-suitable-for-new-terrestrial-wireless-interactive-multimedia-twim-technologies-and-applications-review-the-regulatory-methods-and-appropriate-means-to-facilitate-the-worldwide-harmonization-of-spectrum-for-terrestrial-wireless-interactive-multimedia-and-to-review-service-definitions-in-the-light-of-convergence-of-applications-if-necessary.-in-addition-wrc-2000-adopted-agenda-item-1.21-so-that-wrc-2003-could-review-the-progress-of-these-studies-and-agenda-item-2.15-for-wrc-20056-to-discuss-the-spectrum-and-regulatory-issues-associated-with-twim-applications. .unnumbered}

Studies on TWIM applications were managed by Joint Task Group 1-6-8-9
and carried out through a well-coordinated process since WRC-2000,
drawing on a variety of resources and contributors. The results of the
Joint Task Group's effort indicate that no regulatory impediments to
TWIM applications exist, suggesting that no further ITU-R work is needed
on the TWIM concept. This conclusion is reflected in Method B under
section 7.1.3 (Methods to satisfy the agenda item) of the Draft CPM
Report.

**Proposal:**

**USA/1.21/1**

**[NOC]{.underline}**

**Reason:** No regulatory impediments have been identified to
terrestrial wireless interactive multimedia applications. Study groups
within ITU-R may prepare relevant Questions and continue their work
under the normal activities in order to examine any issues related to
the deployments of terrestrial wireless interactive multimedia
applications.

**USA/1.21/2**

**SUP**

**Resolution 737 (WRC-2000)**

**Review of Spectrum and Regulatory Requirements to Facilitate Worldwide

**Agenda Item 1.22:** To consider progress of ITU-R studies concerning
future development of IMT-2000 and systems beyond IMT-2000, in
accordance with Resolution 228 (WRC-2000).

# Background: WRC-2000 considered issues related to IMT-2000, resulting in the identification of additional spectrum for the terrestrial component of IMT-2000 in the Radio Regulations 5.317A and 5.384A. This spectrum was identified in addition to that initially identified for IMT-2000 at WARC-92 in footnote 5.388. WRC-2000 also identified existing global MSS allocations as being available for use by the satellite component of IMT-2000, in accordance with Resolution 225. {#background-wrc-2000-considered-issues-related-to-imt-2000-resulting-in-the-identification-of-additional-spectrum-for-the-terrestrial-component-of-imt-2000-in-the-radio-regulations-5.317a-and-5.384a.-this-spectrum-was-identified-in-addition-to-that-initially-identified-for-imt-2000-at-warc-92-in-footnote-5.388.-wrc-2000-also-identified-existing-global-mss-allocations-as-being-available-for-use-by-the-satellite-component-of-imt-2000-in-accordance-with-resolution-225. .unnumbered}

In Resolution **228** (WRC-2000), the ITU-R was invited to continue
studies on overall objectives, applications and technical and
operational implementation for the future development of IMT-2000 and
systems beyond. These requirements are to be reviewed by WRC-05/06,
taking into consideration the results of ITU-R studies presented to
WRC-03.

**Proposal:**

**USA/1.22/1**

**[NOC]{.underline}**

Article 5, Frequency Allocations

**Reason:** ITU-R has not completed the studies on spectrum requirements
and potential frequency ranges suitable for the future development of
IMT-2000 and systems beyond IMT-2000.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/141(05.09.02)

**WRC-03 Agenda Item 1.33**: to review and revise technical, operational
and regulatory provisions, including provisional limits in relation to
the operation of high altitude platform stations within IMT‑2000 in the
bands referred to in No. **5.388A**, in response to Resolution **221
(WRC‑2000)**;

**Background:** Provisions for operation of HAPS were originally made at
WRC-97, for HAPS providing FS operations in the 47.2--47.5 GHz and
47.9--48.2 GHz bands (5.552A). A definition of HAPS was also added to
1.66A. The use of HAPS as base stations to provide terrestrial IMT-2000
was approved at WRC-2000, resulting in provisions to facilitate this
being added to the Radio Regulations (5.388A). In accordance with No.
**5.388A**, HAPS may be used as base stations within the terrestrial
component of IMT-2000 in the bands 1** **885-1** **980 MHz,
2** **010-2** **025 MHz and 2** **110-2** **170 MHz in Regions 1 and 3
and 1** **885-1** **980 MHz and 2** **110-2** **160 MHz in Region 2; the
use by IMT‑2000 applications using HAPS as base stations does not
preclude the use of these bands by any station in the services to which
they are allocated and does not establish priority in the Radio
Regulations.

Resolution 221 from WRC-2000 includes provisional co-channel and
out‑of-band power-flux density limits for HAPS operation, for the
protection of other stations either sharing the same band or operating
in adjacent bands and asked for additional technical, operational and
regulatory studies to be conducted, in order to review and, if
necessary, revised, these limits. Resolution 221 also asks for
consideration of appropriate regulatory and technical provisions to
allow bilateral co-ordination of HAPS in an IMT‑2000 system with
affected neighbouring administrations.

Based on updated information on typical noise figure of IMT-2000 mobile
stations, WP-8F updated the protection requirement of other IMT-2000
stations operating co-frequency has been revised to --117 dB
(W/(m^2^MHz)). This PFD threshold is appropriate to protect other
IMT-2000 mobile stations from co-channel interference.

In order to adequately protect MMDS within IMT-2000 in some neighbouring
countries in Region 2 in the band 2 150-2 160 MHz from co-channel
interference, a HAPS operating as a base station to provide IMT-2000
shall not exceed the following co-channel pfd at the Earth's surface
outside an administration's borders unless agreed otherwise by the
administration of the affected neighbouring country:

-- 127 dB(W/(m^2^MHz))for angles of arrival () less than 7° above the
horizontal plane;

-- 127**+** 0.666 ( -- 7) dB(W/(m^2^MHz))for angles of arrival between
7° and 22° above the horizontal plane; and

-- 117 dB(W/(m^2^MHz)) for angles of arrival between 22° and 90° above
the horizontal plane.

It is to be noted that the above is an issue concerning the protection
from co-channel interference of certain stations in some neighbouring
countries in Region 2 only.

*G*(ψ) = *X* -- 60 log (ψ) dBi for ψ2 \< ψ ≤ ψ3

*G*(ψ) = *LF* dBi for ψ3 \< ψ ≤ 90°

where:

~~2 to develop appropriate regulatory and technical provisions to allow
the coordination mentioned in *resolves* 4;~~

~~3 to report on the results of these studies in time for consideration
by WRC‑03.~~

\_\_\_\_\_\_\_\_\_\_\_\_

Reason: The ITU-R has addressed sharing and coordination between HAPS
and existing systems, particularly IMT-2000 stations operating in
adjacent countries and MMDS (multichannel multipoint distribution
service) which are currently operating in the bands 1 885-2 025 MHz and
2 110-2 200 MHz. The Resolution is being modified to reflect the
conclusions of the studies and the PFD thresholds required updating.
Some of the proposed "block" edits to Resolution 221 are merely to
re-organize the text into a more logical manner.

**II. IWG-3: Fixed-Satellite Service/Broadcasting Satellite Service**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/142(05.09.02)

**WRC-03 Agenda Item 1.27**: to review, in accordance with Resolutions
**540 (WRC‑2000)** and **735 (WRC-2000)**, the ITU‑R studies requested
in those resolutions, and modify, as appropriate, the relevant
regulatory procedures and associated sharing criteria contained in
Appendices **30** and **30A** and in the associated provisions;

**Background :** Resolution **540 (WRC-2000)** among other things
invited the ITU-R to undertake, as a matter of urgency, additional
studies and complete them by WRC-03 on the sharing criteria in Annexes
1, 3, 4, and 6 to Appendix **S30** and Annexes 1 and 4 to Appendix
**S30A,** taking into account

that the sharing criteria in Appendices **S30** and **S30A** should
provide appropriate protection to the BSS, FSS and terrestrial services
whilst not unduly constraining the services involved (considering g);

that, worldwide, in various sub-bands of the frequency range 11.7-12.7
GHz, FSS networks as well as BSS networks are in operation, and others
will be operated in the near future and, consequently, difficulties may
be experienced in modifying their characteristics (considering h);

that there are differing geographic situations between the ITU Regions
and that this may have an impact on the sharing criteria...(recognizing
a)

The relevant ITU-R study groups have conducted the requested studies and
the results are presented in Section 3.2 of the CPM Report. The
proposals contained herein take into account these results, noting that
the question of the minimum size of BSS and FSS earth station receiving
antennas to be protected in Region 3 was left open. In that regard, the
proposals contained herein are based on the following general
considerations.

-   Adequate protection should be provided to the BSS and FSS
    assignments in all three Regions,taking into account the
    characteristics of deployed systems as well as the Plan assignments.
    For instance, in Region 2, there are over 17 million 45-cm BSS
    receive antennas deployed, in the coterminous U.S. alone, and BSS
    antennas of up to 240 cm diameter are used in northern Canada,
    Alaska and Hawaii. FSS systems employ an even wider range of receive
    earth station antennas, including some with diameters as large as
    11 m. Similarly, it is necessary to take the requirements of the
    different services and their deployment in Regions 1 and 3 into
    account when developing appropriate inter-Regional sharing criteria.
    And precisely because the protection requirements of a service in
    one Region can differ from those in another Region, it is not
    appropriate to require strict inter-Regional reciprocity; i.e.,
    there is no need to constrain a service in one Region by requiring
    that it provide more protection than the same service in another
    Region requires. The application of inter-Regional reciprocity
    without an operational or technical basis may lead to inefficient
    use of the limited orbital spectrum resources and unnecessary
    contraints on services.

> Based on the above considerations, these proposals outline sharing
> criteria designed to protect BSS receive antennas of 45 cm to 2.4 m in
> Region 2, 60 cm to 2.4 m in Regions 1 and 3 and FSS receive antennas
> of 60 cm to 11m in all ITU Regions. As previously noted, the antenna
> patterns and protection objectives are consistent with those outlined
> in Section 3.2 of the CPM Report.
>
> It is noted that there is still debate on minimum antenna sizes for
> BSS and FSS receive antennas in Regions 1 and 3 and the US will
> continue to monitor studies/data with respect to this issue and update
> its proposals as necessary.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/143(05.09.02)

Draft Proposal for Resolution 136 (WRC-2000)

**WRC-03 Agenda Item 1.29**: to consider the results of studies related
to Resolutions **136** **(WRC‑2000)** and **78** **(WRC‑2000)** dealing
with sharing between non-GSO and GSO systems;

**Background Information:** Resolution 136 invited the ITU-R to
undertake the appropriate technical, operational, and regulatory studies
on sharing arrangements in order to achieve an appropriate balance
between GSO FSS networks and non-GSO FSS systems in the 37.5-50.2 GHz
frequency range.

Both GSO FSS networks and non-GSO FSS systems are planned for operation
within the 37.5-42.5 GHz and 47.2-50.2 GHz bands. FSS systems based on
the use of new technologies associated with both geostationary and
non-geostationary orbits are capable of providing both the most densely
populated and the most isolated regions of the world with high capacity
and low-cost means of communications. WRC-2000, recognizing that there
had been little or no deployment of satellite systems in the band
37.5-50.2 GHz, correctly concluded in Resolution **136 (WRC-2000)** that
both GSO FSS and non-GSO FSS operators should be expected to exhibit
flexibility in achieving the appropriate balance in the sharing
environment, and urged administrations, in the application of Article
**22** to their GSO FSS networks and non-GSO FSS systems in this range
prior to WRC-03, to seek balanced sharing arrangements. Since WRC-2000,
progress was made in compiling information on the characteristics of
both GSO networks and non-GSO FSS systems planned to operate in the
40/50 GHz bands. At the same time, it was recognized that if no
techniques were employed to avoid direct coupling between the main beams
of satellites in a non-GSO system and the main beams of earth stations
in a GSO network, and vice versa, during the short periods when
\"in-line\" transitions occur, the interference in both directions,
which is likely to be modest for the majority of the time, would rise
sharply by many dB for short periods aggregating to small percentages of
time.

To date the ITU-R work done for the 40/50 GHz bands has been fairly
limited. One new recommendation discusses the use of orthogonal
polarizations and other techniques as potential means of sharing between
GSO networks and non-GSO systems in this frequency range. However, the
levels of acceptable interference for GSO FSS networks and non-GSO
systems were not fully assessed. Moreover potentially available
mitigation techniques such as satellite diversity or arc avoidance,
geographic isolation between earth stations, etc., cannot be easily
translated into regulatory provisions that may require the development
of a set of epfd masks to protect GSO FSS networks and of off-axis
e.i.r.p. density masks to protect non-GSO FSS systems.

In most cases sharing between a GSO FSS network and a non-GSO FSS system
of the LEO or MEO type will be feasible only if mitigation techniques to
avoid main beam-to-main beam coupling of \"in-line\" interference are
applied. Such techniques could include, for example:

-   Satellite diversity or arc avoidance;

-   Geographical isolation between earth stations;

-   Adaptive coding;

-   Link balancing

-   Use of orthogonal polarizations.

It is considered premature to conclude on the advantages and
disadvantages of each technique until the further studies have been
accomplished. There is no need for modifications in Article 22 at this
time. Instead, modification of Resolution 136 (WRC-2000) is required to
reflect a new date for completion of studies and action by a future
Conference, and the addition of an appropriate item to a future WRC
agenda.

RESOLUTION 136 (~~WRC-2000~~[REV WRC-03)]{.underline}

Frequency sharing in the range 37.5-50.2 GHz between geostationary\
fixed-satellite service networks and non-geostationary\
fixed-satellite service systems

The World Radiocommunication Conference (~~Istanbul, 2000~~[Geneva,
2003]{.underline})

> considering

*a)* that ~~this Conference has~~[WRC-2000]{.underline} made provisions
for the operation of geostationary fixed-satellite service (GSO FSS)
networks and non-GSO FSS systems in the 10-30 GHz frequency range;

*b)* that there is an emerging interest in operating GSO FSS networks
and non-GSO FSS systems in the 37.5-50.2 GHz range;

*c)* that there is a need to provide for the orderly development and
implementation of new satellite technologies in the 37.5-50.2 GHz
frequency range;

*d)* that systems based on the use of new technologies associated with
both GSO FSS networks and non-GSO FSS systems are capable of providing
the most isolated regions of the world with high-capacity and low-cost
means of communication;

*e)* that there should be equitable access to the radio frequency
spectrum and orbital resources in a mutually acceptable manner that
allows for new entrants in the provision of services;

*f)* that the Radio Regulations should be sufficiently flexible to
accommodate the introduction and implementation of innovative
technologies as they evolve;

*g)* that ~~the CPM Report to WRC-2000 stated that~~ in the bands
37.5-50.2 GHz, where there has been little or no deployment of satellite
systems to date, both GSO FSS and non-GSO FSS operators should be
expected to exhibit flexibility in achieving the appropriate balance in
the sharing environment~~,~~[;]{.underline}

[*h)* that this Conference, having considered the outcome of ITU-R
studies on this subject as summarized in the CPM Report to this
Conference, decided that further studies are needed before the
conditions for non-GSO FSS systems to share these bands with GSO FSS
systems can reliably be determined]{.underline},

resolves to urge administrations

in the application of Article 22 to their GSO FSS networks and non-GSO
FSS systems in the 37.5‑50.2 GHz frequency range prior to
WRC-~~03~~[06]{.underline}, to seek balanced sharing arrangements
between these systems,

invites ITU-R

~~1~~ to undertake, as a matter of urgency, ~~the appropriate~~
[further]{.underline} technical, operational and regulatory studies on
sharing arrangements which achieve an appropriate balance between GSO
FSS networks and non-GSO FSS systems in the frequency range 37.5-50.2
GHz[. Such further studies should embrace, but not necessarily be
limited to:]{.underline}

[a) Techniques which individually or in combination avoid, or otherwise
adequately mitigate, main beam-to-main beam coupling of interference in
both directions between non-GSO FSS and GSO FSS systems at \"in-line\"
instants. The studies should be based on the key parameters of systems
firmly planned to operate in the bands concerned, and should be pursued
sufficiently far to establish appropriate long-term and short-term
interference criteria and to compute the time statistics of interference
from non-GSO system to GSO network, and from GSO network to non-GSO
system, to determine whether those criteria would be met. The
computations and comparisons should be made firstly assuming no
mitigation, and subsequently with each of the various mitigation
techniques or combinations of mitigation techniques envisaged. The
mitigation techniques thus investigated should include:]{.underline}

[• Satellite diversity or arc avoidance.]{.underline}

[• Geographical isolation between earth stations.]{.underline}

[• Site diversity.]{.underline}

[• Adaptive coding.]{.underline}

[• Link balancing.]{.underline}

[• Opposite polarizations for GSO and non-GSO systems.]{.underline}

[• Other appropriate techniques, if any.]{.underline}

[b) The development of technical, operational and regulatory guidance
which would enable WRC-06 to decide whether or not to include, in the
Radio Regulations, epfd limits on non‑GSO FSS systems for the protection
of GSO FSS networks, and off-axis e.i.r.p. density limits on earth
stations in GSO FSS networks for the protection of non-GSO FSS systems,
in the frequency range 37.5-50.2 GHz. Such guidance should include
quantitative values for suitable epfd , epfd and off-axis e.i.r.p.
density limits;]{.underline}

*[instructs the Director of the BR]{.underline}*

~~2~~ to report the results of these studies to
WRC-~~03~~[06]{.underline}.

**Reason:** To allow additional time for the completion of the necessary
ITU-R studies.

**III. Informal Working Group 4: Fixed Service/Fixed-Satellite Service
Sharing**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Doc. WAC/144(05.09.02)**

**WRC-03 Agenda Item 1.13**: to consider regulatory provisions and
possible identification of existing frequency allocations for services
which may be used by high altitude platform stations, taking into
account No. **5.543A** and the results of the ITU-R studies conducted in
accordance with Resolutions **122 (Rev.WRC‑2000)** and **734
(WRC‑2000)**;

**Background:** At WRC-97, the bands 47.2-47.5 GHz and 47.9-48.2 GHz
(which were already allocated for the fixed service) were designated
within the fixed service for High-Altitude Radio-Relay Platform Stations
(HAPS). WRC-2000 confirmed this designation and under Resolution **122**
**(Rev.WRC-2000)** requested that studies continue on regulatory and
sharing issues in these bands. While this designation does not limit the
use of a band by types of services for which it is already allocated, it
does give guidance to administrations wishing to implement specific
service types.

WRC-2000, through Resolution **122**, requested that the ITU-R conduct
studies, taking into account the requirements of other Fixed Service
systems and other services, on the feasibility of identifying suitable
frequencies for the use of HAPS in the Fixed Service in the range 18 --
32 GHz in Region 3. These studies were requested by several Region 3
countries specifically because the previously identified 47 GHz band is
highly susceptible to rain attenuation, and therefore a suitable 2x300
MHz identification in a lower band was needed for HAPS in those
countries. The studies are to focus particularly, but not exclusively,
on the bands 27.5 -- 28.35 GHz and 31.0 -- 31.3 GHz. In addition,
country footnote **5.537A** was adopted to permit the use of HAPS
(HAPS-to-ground) in the fixed service allocation in the band 27.5-28.35
GHz on a non-interference, non-protected basis in certain Region 3
countries and one Region 1 country. This band, by country footnote
**5.543A**, was paired with the 31-31.3 GHz band for use by HAPS
(ground-to-HAPS), also on a non-interference, non-protected basis.
Additionally, use of the 31 -- 31.3 GHz band is subject to not causing
harmful interference to EESS (passive) and RAS services operating in the
31.3-31.8 GHz band. The footnote urged the identified administrations to
utilize only the 31.0-31.15 GHz band until studies were completed.

**[47 GHz Band]{.underline}**

With regard to the bands 47.2-47.5 GHz and 47.9-48.2 GHz, Resolution
**122 (Rev. WRC-2000)** indicated that sharing studies remain to be
completed between the fixed-satellite service (FSS) and HAPS operations
in the fixed service (FS). Pending the completion of studies, Resolution
**122** instructs the Radiocommunication Bureau "that from 22 November
1997, and pending review of the sharing studies in considering h) and
review of the notification process by WRC-99, the Bureau shall accept
notices in the bands 47.2-47.5 GHz and 47.9-48.2 GHz only for high
altitude platform stations in the fixed service and for feeder links for
the broadcasting-satellite service, shall continue to process notices
for fixed-satellite service 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.

The studies in this band have been completed and the results are
contained in Recommendation ITU-R SF.1481. 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 -- in
particular, if HAPS networks in this band are not used to provide
ubiquitous service and if FSS earth stations utilize antennas with
diameters of at least 2.4 m or other types of antennas with similar
performance -- can be addressed through coordination using Articles 9
and 11 of the Radio Regulations. As a result, all portions of Resolution
122 dealing with the 47 GHz band can be suppressed, provided that
reference to the use of Article 9 for HAPS is included in the Radio
Regulations.

**[27 and 31 GHz Bands]{.underline}**

To date, all sharing studies in the 18-32 GHz range under Resolution 122
within the ITU-R have focused exclusively on the bands 27.5-28.35 GHz
and 31.0-31.3 GHz.

No. **5.543A** of the Radio Regulations provides that the allocation to
the fixed service in the band 31.0-31.3 GHz may also be used by HAPS in
the ground-to-HAPS direction in certain countries. In such cases, HAPS
uplinks in the band 31.0‑31.3 GHz shall not cause harmful interference
to, nor claim protection from, other fixed‑service systems or other
co‑primary services, as indicated in No. **5.543A**. In addition, the
use of HAPS in the band 31.0‑31.3 GHz shall not cause harmful
interference to the passive services having a primary allocation in the
band 31.3‑31.8 GHz. The ITU-R has not yet developed Recommendations
regarding the compatibility between HAPS and the EESS (passive) and RAS.

No. **5.537A** of the Radio Regulations provides that the allocation to
the fixed service in the band 27.5-28.35 GHz may also be used by HAPS in
certain countries listed in No. **5.537A**. The use of the fixed service
allocation at 27.5-28.35 GHz by HAPS is 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. The ITU-R has adopted a new Recommendation \[Doc.
4/89-9/148\] containing a methodology for evaluating interference from
HAPS-to-ground transmissions to FSS earth-to-space transmissions,
however specific protection criteria have not yet been agreed.

The same concerns expressed at WRC-00 by many Administrations, including
the U.S., with respect to identifying HAPS use in the fixed service in
the 18 -- 32 GHz band are still valid today. Internationally the FSS is
allocated on a global basis in the 17.7 -- 21.2 GHz and 27.5 -- 31.0 GHz
bands and the FSS community has invested large amounts of resources and
time in the development of global FSS systems that operate or are
planned to operate in these bands. The FSS community remains very
concerned about their ability to deploy already planned global FSS
satellite systems in these bands without hindrance from HAPS deployment
in the same bands. Additionally, there is concern regarding
compatibility of HAPS with existing global FSS systems that operate in
these bands. Given that the original intent of these studies was to find
a suitable alternative to the 2x300 MHz of spectrum identified for FS
HAPS at 47 GHz in Region 3, and the fact that the 27.5-28.35 GHz range
is the only range that has been considered for the HAPS-to-ground
direction for this alternative, narrowing the frequency range of
consideration for potential HAPS services to a specific and common 300
MHz band within the 27.5-28.35 GHz range in all of the countries listed
in No. **5.537A** would help to ease the concerns of the FSS in this
regard and would bring any final allocation decision in line with the
original intent of WRC-2000. Identification of a specific and common 300
MHz band within this frequency range would also facilitate the design
and implementation of HAPS systems in this band.

The EESS (passive) and RAS service communities are also very concerned
about the possibility of interference from HAPS FS stations in the
31--31.3 GHz band, which is adjacent to the 31.3-31.5 GHz passive band
allocated on a primary basis to the Earth exploration-satellite
(passive) and space research (passive) services for passive remote
sensing of the Earth. This passive sensing band is of vital importance
in Earth observation and weather forecasting because it is the reference
band used in conjunction with the unique oxygen absorption bands from
50.2--59.3 GHz. Unwanted interference in this band from out-of-band
emissions from HAPS would be particularly harmful to the remote sensing
use of the band. The 31.3-31.8 GHz band is also allocated to the RAS on
a primary basis, and is extensively used, e.g. for studies of the Cosmic
Microwave Background.

For the case of HAPS compatibility with passive services (both passive
sensing and radio astronomy service), studies have indicated that
certain types of HAPS systems may be compatible with these passive
services. HAPS uplinks may have to operate with certain constraints in
order to limit unwanted emissions; however, experimental hardware has
been developed to demonstrate the feasibility of such operation. The
results of these studies leading to compatible operation between HAPS
and passive services should be incorporated in an ITU-R
Recommendation(s).

**Proposal:**

**USA/1.13/1**

**MOD**

**5.537A** In Bhutan, Indonesia, Iran (Islamic Republic of), Japan,
Maldives, Mongolia, Myanmar, Pakistan, the Dem. People's Rep. of Korea,
Sri Lanka, Thailand and Viet Nam, the allocation to the fixed service in
the band 27.5‑28.35 GHz may also be used by high altitude platform
stations (HAPS). The use of [HAPS within]{.underline} the band
27.5-28.35 GHz ~~by HAPS~~ is limited [within the territory of each
Administration to a single 300 MHz sub-band. Such use of 300 MHz of the
FS allocation by HAPS in the above countries is further
limited]{.underline} 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. [See
Resolution **HAPS 28-31 (WRC-03)**.]{.underline}
(WRC‑200[3]{.underline}~~0~~)

**Reason:** The identification of 300 MHz of spectrum within the band
27.5-28.35 GHz, along with the 300 MHz at 31-31.3 GHz, is intended to be
an alternative for the 2x300 MHz that is problematic in the specified
countries due to excessive rain attenuation at 47 GHz. This proposal
implements that intent by limiting use of HAPS in the named
Administrations to 300 MHz within the identified 850 MHz frequency range
identified at WRC-2000. The second 300 MHz band is found at 31-31.3 GHz
(see proposal **USA/1.13/2** below). This proposal also incorporates the
provisions of new Resolution **HAPS 28-31 (WRC-03)** into the Radio
Regulations.

**Reason:** ITU-R studies conducted to date have demonstrated that
certain HAPS system designs, operating with certain constraints, could
operate on a non-interference basis and appropriately protect other
systems and services. In addition, these studies have shown that HAPS
can operate without the need for claiming protection. Given that HAPS
applications in the FS and the adjacent services are of different status
and operate in different bands, the results of studies should remain
within the ITU-R and not result in specific limits within No.

**Reason:** Consequential to the SUP 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.
The reference to Resolution **HAPS 28-31** reflects the intent of
WRC-2000 that the identification of 2 x 300 MHz of FS spectrum at
27.5-28.35 GHz and 31-31.3 GHz in certain countries is intended as an
alternative for the HAPS designation at 47 GHz which is problematic in
those countries due to excessive rain attenuation. Nos. **9.15** and
**9.16**, which apply to coordinations regarding non-GSO FSS earth
stations and terrestrial stations (including HAPS) need to be called out

RESOLUTION HAPS 28-31 (WRC-03)

Potential use of 300 MHz of spectrum within the band 27.5-28.35 GHz and
300 MHz of spectrum at 31.0-31.3 GHz by high altitude platform stations
(HAPS) in the fixed service

The World Radiocommunication Conference (Geneva, 2003),

considering

*a)* that WRC‑97 made provision for operation of HAPS, also known as
stratospheric repeaters, within a 2x300 MHz portion of the fixed service
allocation in the bands 47.2-47.5 GHz and 47.9-48.2 GHz;

*b)* that WRC-97 adopted No. **4.15A** specifying that transmissions to
or from high altitude platform stations shall be limited to bands
specifically identified in Article **5**;

*c)* that at WRC-00, several countries in Region 3 and one country in
Region 1 expressed a need for an alternative band pairing for HAPS in a
lower frequency range due to the excessive rain attenuation that occurs
at 47 GHz in these countries;

*d)* that, in order to accommodate the need expressed by the countries
referred to in *considering c),* WRC-03 adopted Nos. **5.537A** and
**5.543A** to permit the use of HAPS in the fixed service within 300 MHz
of spectrum in the band 27.5-28.35 GHz and/or in the band 31.0-31.3 GHz
in certain Region 3 countries and in one Region 1 country on a
non-interference, non-protection basis;

*e)* that the bands 27.5-28.35 GHz and 31.0-31.3 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;

*f)* that the 31.3-31.8 GHz band is allocated to the radio astronomy,
Earth exploration-satellite (passive) and space research (passive)
services, and the 31.8-32.3 GHz band is allocated to the space research
(deep space) service, and that there is a need to appropriately protect
these services from unwanted emissions, taking into account No.

*h)* that pending the completion of studies, it may be appropriate for
administrations that wish to consider deployment of HAPS systems in the
fixed service within 300 MHz of spectrum at 27.5-28.35 GHz and/or in 300
MHz of spectrum at 31-31.3 GHz to have some provisional means by which
to authorize such use of HAPS in their territories without being in
derogation of the Radio Regulations,

resolves

1 \"to invite WRC-06 to review the results of the studies specified
below with a view to considering appropriate revisions of the
regulations affecting high altitude platform systems, within 300 MHz. of
spectrum within the bands 27.5-28.35 GHz and/or 300 MHz of spectrum at
31.0-31.3 GHz

2 that pending the completion of the studies specified in *requests
ITU-R* 1 below, and notwithstanding the applicability of No. **4.15A**
of the Radio Regulations, the use by HAPS stations of 300 MHz of the
fixed service allocation within the band 27.5-28.35 GHz and/or in the
31-31.3 GHz band, within the territory of any Administration that so
desires but that is not listed in Nos. **5.537A** and **5.543A**, is

HAPS-to-ground direction, and that any use by HAPS of the fixed service
allocation at 31-31.3 GHz pursuant to *resolves 2* above shall be
limited to operation in the ground-to-HAPS direction,

requests ITU-R

1 to continue to conduct studies, as a matter of urgency, and taking
into account the requirements of other fixed-service systems and other
services, on the feasibility of identifying a suitable and common 300
MHz segment of the band 27.5-28.35 GHz, in addition to the 300 MHz band
at 31-31.3 GHz, as an alternative to the 2x300 MHz paired band at 47
GHz, for the use by HAPS in the countries listed in Nos. **5.537A** and
**5.543A**;

2 to incorporate in an ITU-R Recommendation(s) technical sharing
criteria or HAPS system design constraints that are necessary to ensure
that HAPS applications in the fixed service are able to be operated
successfully on a non-interference, non-protection basis with other
fixed service systems and with stations, systems, and networks of
co-primary services.

*invites*

Administrations planning to implement HAPS systems within the band
27.5-28.35 GHz and/or in the band 31.0-31.3 GHz, whether in countries
listed in Nos. **5.537A** and **5.543A** or not, to advise the
Radiocommunication Bureau as soon as practicable of their intention to
do so and of what specific frequencies (up to 300 MHz each within the
27.5-28.35 GHz and 31-31.3 GHz bands) are intended to be used for such
systems;

*requests the Radiocommunication Bureau*

to publish within 90 days after the end of WRC-03 a list of
administrations who have so advised, and thereafter to publish within 90
days updates containing the names of administrations who advise
subsequently.

**Reason:** ITU-R studies conducted to date have demonstrated that
certain HAPS system designs, operating with certain constraints, could
operate on a non-interference basis in the bands identified by WRC-00
and appropriately protect other systems and services. Appropriate
interference allowances would have to be developed and agreed within the
ITU-R for such cases. In addition, these studies have shown that HAPS
can operate without the need for claiming protection. The technical
details and constraints of such systems would need to be incorporated in
ITU-R Recommendations(s) to ensure that other systems and services are
protected. Pending completion of the studies, it would be acceptable to
suspend the operation of No. **4.15A**, thereby allowing provisional
operation of HAPS on a non-interference basis under No. **4.4** of the
Radio Regulations, in 300 MHz of the 27.5-28.35 GHz band and/or in the
31-31.3 GHz band. The Bureau would maintain and publish a list (to be
updated periodically) of countries where HAPS systems are planned for
implementation, and the precise frequencies to be used. Finally, a
specific 300 MHz portion of the 27.5-28.35 GHz band needs to be
identified for pairing with 31.0-31.3 GHz.

Annex

Minority view for "*resolves* 2"

2 that pending the completion of the studies specified in *requests
ITU-R* 1 below, No. **4.15A** of the Radio Regulations shall be
provisionally suspended in 300 MHz of the fixed service allocation
within the band 27.5-28.35 GHz and/or in the 31-31.3 GHz band within the
territory of any Administration that so desires, provided that a HAPS
station, when using an assignment in these bands, shall not cause
harmful interference to, nor claim protection from, other types of
fixed-service systems or other co-primary services;

This wording requires consequential changes to the **Reason** for
Resolution 28-31 (WRC-03)

**Reason:** ITU-R studies conducted to date have demonstrated that
certain HAPS system designs, operating with certain constraints, could
operate on a non-interference basis in the bands 27 and 31 GHz bands
identified by WRC-00, and can appropriately protect other systems and
services from harmful interference. These studies have also shown that
HAPS can operate without the need to claim protection from other systems
and co-primary services. Provisional suspension of No. **4.15A**, would
allow other countries to authorize HAPS operations within their
territories on a non-interference basis in 300 MHz of the 27.5-28.35 GHz
band and/or the 31-31.3 GHz band. The ITU Radiocommunication Bureau
would maintain and publish a list (to be updated periodically) of
countries where HAPS systems are planned for implementation, their
frequencies and operational characteristics.

## SkyTower Comments and Rationale in Support of the Minority View {#skytower-comments-and-rationale-in-support-of-the-minority-view .unnumbered}

The Sky Tower version of the US proposal for agenda item 1.13 (HAPS)
differs from the majority proposal in only one respect: the regulatory
status to be accorded HAPS in additional countries after WRC-03.
Identical to the majority version, it proposes that HAPS operation in
additional countries be subject to the same prohibition against causing
harmful interference, and against claiming protection from interference
from fixed service systems, and other primary services, that applies to
the countries now named in the existing footnote Radio Regulations. In
contrast, the majority proposal would permit new countries to operate
HAPS systems only in "derogation" of the Radio Regulations under Article
4.4 That is a stultifying, handicapping, anti-competitive, difference
which is harmful to the development of HAPS systems.

No service that has an allocation in the Table of Frequency Allocations
looks forward to the prospect of having to share its allocation with
other users. But sharing with new users that have either demonstrated
that sharing is feasible, or who are obliged to operate in a band under
the conditions that no harmful interference shall be caused, and that no
protection from interference shall be claimed, is the only way that new
services can come in to operation.

The concerns of existing services over the possibility of interference
from a new user of their band are real and justified. But the essential
question that must be answered by the allocating authorities \--
international and domestic -- is whether the reasons advanced by the
incumbent service or services are real, justified, and reasonable. Do
the objections have technical and regulatory merit, or are they simply
negative NIMBY reactions to sharing with a new service, or are they the
consequence of anti-competitive motivations?

SkyTower is in complete and total agreement with the \"majority view\"
that HAPS operations should not cause harmful interference to nor claim
protection from interference from other FS systems or other services
sharing the band. Within the IWG 4, all parties have agreed that HAPS
operations within 300 MHz of the band 27.5-28.35 GHz is acceptable under
these conditions and the difference between the participants is in the
regulatory status to be accorded HAPS in additional countries under the
modified Radio Regulations.

During the months of deliberations of IWG-4, consensus was reached among
all participants on the fundamental aspects of a US Proposal for HAPS:
countries in addition to those now named in the existing footnote
Regulations could authorize HAPS in 300 MHz out of the 850 MHz bandwidth
of the 27.5-28.35 GHz band; and a specific, common 300 MHz would
eventually be designated.

However, to achieve that consensus SkyTower was forced to make many
costly concessions, including:

-   redesign of its 850 MHz system to be able to operate within 300 MHz:
    this was a major and costly concession as it involved the
    introduction of multiple spot beams for frequency re-use and the
    consequent costly weight and power limitations;

-   

-   agreeing to restrictive limitations on both aggregate and single
    entry pfd at the orbit;

-   

-   giving assurances to FS interests within the US that any domestic
    use would be through appropriate arrangements with them, recognizing
    their rights to the spectrum and notwithstanding that the likelihood
    of interference from the HAPS stations to FS stations is small,

-   

-   agreeing to accept any interference into its system and to design it
    accordingly, and

-   

-   agreeing to the removal of the advantage given to HAPS at 47 GHz by
    WRC 97 so that the BR would be able to accept filings from the FSS
    after WRC 03.

All of these were major concessions on the part of SkyTower, since they
had not been incorporated in the already advanced design stages of the
system. In exchange for these concessions, all parties agreed to the
suspension of Radio Regulation 4.15A in the relevant bands. Initially
this suspension was to be stated within footnotes 5.537A and 543A.
However, because of several last minute difficulties with introducing
technical constraints (i.e. PFD limits) in RR footnotes (which would
have implied a specific definition of the term "harmful interference),
and especially because these constraints had not been the result of
ITU-R studies, it was decided not to modify the footnotes but rather to
include the proposals for use by additional countries in a modification
of existing ITU Resolution 28-31. In so doing, SkyTower expected, and
was led to believe, that the elements that had been proposed for
inclusion in 5.537A would be incorporated in the modified Resolution.

[The development of HAPS in additional countries would be seriously
handicapped if required to operate under Radio Regulation
4.4]{.underline}

The current majority wording would throw HAPS back to operation under
Article 4.4 of the Regulations. Article 4.4 status is no status at all.
It makes all such operations pariahs outside all of the other
Regulations. Even the word used in that Regulation make operation under
4.4 an outcast: such stations may operate "*in* *derogation"* of the
Table of Frequency Allocations" etc., etc. But what comes after the etc.
, etc., is exactly the same protection to services sharing the bands
with HAPS that are contained in SkyTower's *resolves 2*

But the difference between status that mandates protection to other
services, and a no-status status, is crucial to prospective investors,
operators, and customers. If SkyTower is to have a chance to interest
investors, and to sell its goods and services to operators and customers
around the world -- and to create jobs for American, revenue from
overseas to American companies, and taxes to the US Treasury \--, it
must be given the minimal recognition implied by status as an
"essentially secondary" operation.

**IV. Informal Working Group 7: Regulatory Issues and Future Agendas**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/145(05.09.02)

**WRC-03 Agenda Item 1.30e:** to consider possible changes to the
procedures for the advance publication, coordination and notification of
satellite networks in response to Resolution **86** (Minneapolis, 1998);

**Background**

Even where agreement between concerned administrations is reached, the
existing Radio Regulations have no provisions that allow for the
notification of typical earth stations in the fixed satellite service
(FSS) and typical stations in the fixed (FS) service for bands allocated
above 100 MHz with equal rights to the FSS and the FS services.

Both these services are implementing large numbers of stations under
single authorizations and they would both benefit from regulations that
would facilitate the introduction of such stations through the
elimination of the need for specific site coordination and notification
of every station in such a group.

**Fixed-Satellite Service Stations**

A large number of Fixed Satellite Service (FSS) earth stations are
frequently authorized by an administration as a group under a single
license. Such authorizations may encompass hundreds or even thousands of
such stations to be used in the area of a particular administration.
Under the current Radio Regulations, to be recorded in the International
Frequency List, each and every one of these stations would require
individual site notification in bands where the FSS is co-primary with
the FS. Such a situation would be triggered under No. 9.17, in relation
to 9.6 and 9.27 (ref. to Appendix 5).

No. 9.17 states inter alia; that coordination is required:

"for any specific earth station or typical mobile earth station in
frequency bands above 100 MHz allocated with equal rights to space and
terrestrial services in the territory of another country, with the
exception of the coordination under 9.15."

Coordination under this regulation for a large group of FSS earth
stations would be a long and cumbersome process, as it would require
coordination to be carried out on a site-by-site basis. Under the
current regulations, if such coordination were not carried out:

-   Receiving FSS earth stations would not be protected from harmful
    interference from terrestrial stations or earth stations operating
    in the opposite direction of transmissions;

-   Transmitting FSS earth stations would have to take steps to
    eliminate harmful interference caused to existing and future
    terrestrial stations, or earth stations operating in the opposite
    direction of transmission;

-   FSS receive/transmit earth stations would not be required to
    coordinate if their coordination area does not overlap with the
    territory of another country.

Fixed Service Stations

A large group of fixed stations can similarly be authorized as a group
under a single license in bands shared with space services. These
stations may be low density or high density systems, or a hybrid of low
density and high density configurations. Such fixed systems may be
implemented under a geographic area authorization within which the
operator is permitted to manage interference margins and deploy links
with minimal coordination requirements. In addition, operators may be
authorized to add, remove or relocate facilities within the geographic
area without prior authorization. Maintaining this minimal requirement
for coordination is critical to allow the operator the necessary
flexibility to meet the ever changing user needs characteristic of these
high density networks which are premises located. These types of fixed
service networks have characteristics similar to temporary fixed and
mobile uses. Recommendation ITU-R F.1498 states that in service areas
where there is dense deployment of fixed service stations, coordination
with and by fixed satellite service earth stations should be carried out
on an area basis rather than a station to station basis. Such system
deployments can undergo substantial deployment changes, even in short
periods of time due to additional network link deployments, their shut
down, or movement during day-to-day operations. Accordingly, these
systems are substantially similar to area-wide mobile service systems
when subjected to coordination requirements, especially if those
coordination requirements include coordinating with other services whose
systems require multi-year deployment planning.

Under the current Radio Regulations, each and every fixed station would
require individual site coordination with Earth stations in bands where
the FSS is co-primary with the FS. Such a situation would be triggered
under RR 9.18 which states that coordination is required for any
transmitting station of a service, in the bands referred to in No. 9.17,
within the coordination area of an Earth station. RR 11.17 states
"Frequency assignments relating to a number of stations or earth
stations may be notified in the form of characteristics of a typical
station or typical earth station and the intended geographical area of
operation. Except for mobile earth stations, individual notices of
frequency assignments are however necessary in the following cases:".
One of the cases listed is RR 11.20, terrestrial stations within the
coordination area of an Earth station.

This case would require typical fixed stations which may have been in
operation for many years to now be notified with specific site
characteristics and for the operator to project what changes and
additions may occur, either within three months under RR 9.52, if the
administration does not agree to the request for coordination or three
years under RR 9.52B, if there is an agreement on coordination.

This is a difficult and onerous requirement that should be addressed
through modifications in the Radio Regulations for the particular bands
where there is the deployment of a high density of Fixed Service
stations.

**Approaches to Regulation of Groups of FS/FSS Stations**

Below are descriptions of concepts on how to facilitate the coordination
of FSS earth stations and FS stations that have similar technical
characteristics, and are authorized in large groups under a single
license.

There are several approaches that could be used, some of which were
identified in WP 4-9S CPM text for agenda 1.30. These are described
below:

**A. No change to the Radio Regulations**

This method would keep the current relation of sharing between FSS and
terrestrial services, allowing to take due account of the actual and
expected (within the next 3 years) terrestrial deployment and of the
geographical situation. However, applying the procedure for specific
earth stations to a large group of FSS earth stations would be a long
process.

It was noted that this long process could be alleviated at the
coordination stage, by the use of any new or existing methodology in
bilateral discussions between the administrations concerned. This
methodology could be made available through an ITU-R Recommendation.
This methodology would rely on the availability of a database where
terrestrial stations and earth stations would be recorded. This
database, to serve its purpose, would need to contain accurate updated
information. Moreover, its availability for neighboring countries would
need to be ensured.

The usefulness of this approach is highly dependent on availability of
the referenced new methods and an accurate database.

B.  **Changes affecting the coordination and notification of Typical
    Stations**

**Typical Earth Stations**

This approach would entail modification of the Radio Regulations to
provide for typical FSS earth stations in specific frequency bands
through regulations which provide for the coordination and notification
of such stations as a consequence of agreements between administrations
concerned. On this basis, the coordination area around these types of
earth stations would be incorporated into Appendix 7.

This would address the need to provide protection to FSS earth stations
deployed in large groups, and avoid the situation where such stations
would have to be coordinated and/or notified as specific earth stations
or operate on a \"non-interference\" or \"non-protected\" basis.

Typical Fixed Stations

A similar modification of the Radio Regulations could be made to provide
for typical fixed stations to be notified within a specific geographic
area and within certain frequency bands without the further requirement
for specific site notification and coordination when there is a future
request for coordination with an FSS Earth station, where the frequency
bands of the Earth Station and the terrestrial station overlap and the
coordination area of the Earth station covers the territory of another
administration.

Such regulations would address the need to avoid the situation where
such stations would have to be coordinated and/or notified as specific
stations or operate on a \"non-interference\" or \"non-protected\"
basis.

ADD Section 1.4.8 in Appendix 7

1.4.8 Typical FSS Earth Stations

For a group of FSS earth stations under a single authorization, the
coordination area is determined by extending the periphery of the
specified service area within which such earth stations are operating by
the coordination distance of 100 Km (pre-determined).

**Reason:** The modifications to the RR proposed in USA/1.30/TES1-6 will
provide a basis for typical earth station and fixed stations to be
coordinated and notified in identified allocations where the space and
fixed services have equal status, and will not upset the balance between
the services.

There will be enormous benefit to such stations when they are part of a
large group of such stations authorized under a single license as they
will be relieved of the regulatory burden of having to coordinate and
notify each station in such a group on the basis of individual sites.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/146(05.09.02)

**WRC-03 Agenda Item 1.30f:** to consider possible changes to the
procedures for the advance publication, coordination and notification of
satellite networks in response to Resolution **86** (Minneapolis, 1998);

**Background:**

Recently the RRB clarified the application of Resolution 539, "Use of
the band 2630 -- 2655 MHz in certain Region 3 countries by
non-geostationary satellite systems in the broadcasting-satellite
service (sound)". The band addressed in Resolution 539 has been
allocated to various services for some time and the regulatory
provisions that apply between the satellite and terrestrial systems in
this band have been long established.

WRC-2000 adopted (i) regulations that allow coordination between NGSO
BSS(S) systems and GSO systems in the 2630 -- 2655 MHz band; (ii) a
footnote that identifies that band, among others, for possible use by
IMT-2000 systems; and (iii) Resolution 539 which includes certain
technical limitations on the NGSO BSS(S) systems that can be deployed
and power flux density thresholds for the Bureau to identify
administrations whose terrestrial service may be affected by the
proposed NGSO BSS(S) network.

There has been some debate on the interpretation of Resolution 539
however the applicable procedures have been clarified in a ROP, which
decided that the coordination requests of such systems will be subject
to the application of Resolution 539 within the existing procedure of
No. 9.11 of the Radio Regulations. In order to clarify this in the Radio
Regulation the following modifications to the Radio Regulations are
proposed.

The importance of the proposal below lies in enforcing the concept that
« seeking agreement» means have coordination, and that this in turn
becomes an « implicit » rather than an « explicit » requirement.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/147(05.09.02)

*Advisory committee revision of NTIA proposal (Doc. WAC/137(05.09.02))*

> **WRC-03 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
> **801 (WRC‑2000)**,

Resolution 801 (WRC-2000), Agenda Item 2.12: to consider spectrum
requirements for wideband aeronautical telemetry in the band between 3
GHz and 30 GHz;

**Background Information**: The World Radiocommunication Conference 2000
included item 2.12 in the preliminary agenda for the World
Radiocommunication Conference 05/06. The 2000 Radiocommunication
Assembly approved Question ITU-R 231/8, titled: *Operation of wideband
aeronautical telemetry in bands above 3 GHz*. The 2000
Radiocommunication Assembly directed that Question ITU-R 231/8 studies
be completed by 2005. ITU-R Circular letter CA/109 requested
administrations and Sector Members to supply data on existing and
planned wideband aeronautical telemetry systems operating at frequencies
above 3 GHz. In this circular letter Wideband Aeronautical Telemetry is
defined as ~~: Emerging Telemetry Systems With Large Data Transfer
Requirements to Support New and Different Telemetry Capabilities (such
as high resolution video and associated data for remotely-piloted
aeronautical vehicles). It is further defined as telemetry~~ [emerging
telemetry systems with large data transfer requirements]{.underline}
generally requiring a bandwidth of 20 MHz or greater.

The wideband requirements addressed under this WRC-06 proposal are in
addition to those presently operating in the existing aeronautical
telemetry allocations below 3 GHz (in the 1 429-1 525 and 2 300-2 390
MHz bands.) The requirement for these allocations will continue. Rather,
the allocation addressed in this proposal is for new wideband
requirements.

The responses to ITU-R Circular letter CA/109 indicated that there are
requirements for additional telemetry spectrum, up to 300 MHz
contiguous, for wideband aeronautical telemetry. There has been a trend
toward cooperation and multi-platform testing that is leading to a need
for identification of additional harmonized band(s) for aeronautical
telemetry. As airframe speed, ~~missions~~ [applications]{.underline},
and technology increase there is an expanding need for new and more
numerous telemetry points for real-time ~~testing of aircraft to ensure
each platform is rigorously tested and evaluated to ensure safety on
these high technology platforms~~ [evaluation to ensure the safety and
integrity of each aircraft]{.underline}. Numerous Administrations have a
need for advanced telemetry ~~testing of multiple~~
[involving]{.underline} platforms in complex environments; this
~~testing~~ is often carried out on a cooperative basis with other
Administrations. By designating a harmonized wideband aeronautical
telemetry band between 3 and 30 GHz, the need for this type of ~~testing
can be met.~~ [application can be met. It is anticipated that a draft

(WRC‑2000)**,

**Background Information**: The Table of Frequency Allocations currently
extends to 275 GHz. Footnote **5.565,** which was modified by WRC-2000
to identify bands for passive service, states:

> **5.565** The frequency band 275-1 000 GHz may be used by
> administrations for experimentation with, and development of, various
> active and passive services. In this band a need has been identified

> \- radio astronomy service: 275-323 GHz, 327-371 GHz, 388-424 GHz,
> 426-442 GHz, 453-510 GHz, 623-711 GHz, 795-909 GHz and 926-945 GHz;

> 363-365 GHz, 371-389 GHz, 416-434 GHz, 442-444 GHz, 496-506 GHz,
> 546-568 GHz, 624-629 GHz, 634-654 GHz, 659-661 GHz, 684-692 GHz,
> 730-732 GHz, 851-853 GHz and 951-956 GHz.
>

The science services have made extensive use of the spectrum above 275
GHz for several decades now, mostly through passive applications. A
number of radio astronomy observatories operate in this area of the
spectrum. Several major new instruments are planned, or are under
construction and expect to begin operating in this range in the next few
years. Foremost among these is ALMA, an international collaboration
between the United States and a consortium of European countries, to
build and operate a millimeter wavelength telescope that will be
comprised of 64 antennas located in the Chajnantor region of the Chilean
Andes.

Likewise, there are already spaceborne passive sensors utilizing
frequency bands in the above 275 GHz region of the spectrum, and many
more are planned for other bands. Among these is the Microwave Limb
Sounder (MLS) planned for launch on the Aura satellite in July 2003. The
MLS, which is an enhanced version of the payload currently operating on
the Upper Atmospheric Research Satellite (UARS), will provide data vital
to the understanding of ozone depletion, transformation of greenhouse
gases, and radiative forcing of climate change.

In addition to science-related passive service applications, research
and experiments in use of the 275 to 1 000 GHz band for various active
service applications has also been underway for some time. Although the
propagation characteristics of the band within the earth's atmosphere
(i.e., absorption and scattering) limit the usable range of most active
systems compared to their use in lower frequency bands, there are also
some benefits. These include an increase in range and angular resolution
for radiolocation applications, resulting in the ability to discriminate
"targets" that are much closer together than could be achieved in lower
bands. For terrestrial communications, the severe propagation path loss
conditions in this band facilitate frequency reuse and increases privacy
for those that need it. Also, the bandwidth available in these higher
frequency regions provides the opportunity for extremely high data rate
communications and high processing gains for spread spectrum systems.
Active applications in space are not impacted by the atmosphere and
therefore receive the full benefit associated with the use of these
higher bands.

Additionally, the Plenipotentiary Conference will be considering Inter
American Proposals (IAPs) to remove the 3 000 GHz limit from the note to
the definition of \"radiocommunication\" in the ITU and an accompanying
Resolution inviting future World Radiocommunication Conferences to
revise the terms and definitions in the Radio Regulations, with a view
towards harmonization.

addressing spectrum above 3 000 GHz in order to align definitions in the
Radio Regulations and by doing so establish a mechanism through which
future spectrum issues of an international character can be addressed.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/131(22.07.02)

**WRC-03 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 **801
(WRC‑2000)**,

**HAPS at 2 GHz**

**Background:** The identification of certain frequency bands for HAPS
operating as base stations to provide terrestrial IMT-2000 was made at
WRC-2000, resulting in provisions to facilitate this being added to the
Radio Regulations (5.388A). Resolution 221 from WRC-2000 includes
provisional co-channel and out‑of-band power-flux density limits for
HAPS operation, for the protection of other stations either sharing the
same band or operating in adjacent bands.

Resolution 221 asked for additional technical, operational and
regulatory studies to be conducted, in order to review and, if
necessary, revise, these limits. Resolution 221 also asked for
consideration of appropriate regulatory and technical provisions to
allow bilateral co-ordination of HAPS in an IMT‑2000 system with
affected neighboring administrations.

Based on the results of ITU-R studies, WRC-2003 is expected to adopt
technical and operational provisions, including revised PFD thresholds
for the operation of high altitude platform stations (HAPS) within
IMT-2000 in the bands referred to in No. **5.388A**. The technical
factors that should be considered during such a consultation are the
subject of a PDNR at Working Party 8F (WP8F/TEMP/277). Provisional
regulatory provisions for HAPS are also expected to be adopted.

**Proposal for WRC-2006 Agenda**

**USA/7.2/1 ADD**

Agenda Item X.X

"to review the provisional regulatory provisions, notification and the
consultation process in relation to the operation of high altitude
platform stations (HAPS) within IMT-2000 in the bands referred to in No.
**5.388A**, in response to Resolution **221 (\[WRC-2003\]**) with a view
toward incorporating the provisions into the Radio Regulations."

Reason: Provisional regulatory provisions for HAPS within IMT-2000 are
likely to be adopted by WRC-2003. These procedures are likely to be
contained in a modification to Resolution 221 and will define a
notification and consultation process. Neighboring administrations will
be consulted if the power-flux density (pfd) thresholds are exceeded on
their territory.

Doc. WAC/150(05.09.02)

**WRC-03 Agenda Item 4**: in accordance with Resolution **95
(Rev.WRC-2000)**, to review the resolutions and recommendations of
previous conferences with a view to their possible revision, replacement
or abrogation;

**Background:**

Recommendation 719 was agreed at WARC-92. It concerned multi-service
satellite networks using the geostationay-satellite orbit and it
recognized that, at that time, some administrations had expressed an
interest in developing multiservice satellite networks in certain
portions of the Ka-band. Related studies on the technical
characteristics and sharing criteria necessary for compatible operations
between mutiservice satellite networks and the fixed-satellite service
were carried out by WP-4A in 1994 and the results of these studies
indicated the difficulty associated with sharing between the multiple
services of the FSS and the MSS in the same frequency allocation,
*e.g.,* 19.7-20.2 GHz/29.5-30.0 GHz.

Little work has been done within the ITU-R on this subject since that
time. As a consequence of the initial ITU-R studies, there appears to be
little ongoing interest on the part of administrations in continuing to
pursue multiservice satellite networks. Considering all of this, it is
appropriate to suppress Recommendation 719.

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

**Doc. WAC/138(05.09.02)**

**WRC-03 Agenda Item 1.9**: to consider Appendix **13** and Resolution
**331 (Rev.WRC-97)** with a view to their deletion and, if appropriate,
to consider related changes to Chapter VII and other provisions of the
Radio Regulations, as necessary, taking into account the continued
transition to and introduction of the Global Maritime Distress and
Safety System (GMDSS);

**Background Information**: In accordance with the International
Convention for the Safety of Life at Sea (SOLAS), 1974, as amended, all
ships subject to this convention were fitted for the Global Maritime
Distress and Safety System (GMDSS) by 1 February 1999. During the
transition period to full implementation of the GMDSS, the RR had dual
provisions; Appendix **13** includes the non-GMDSS provisions. Although
many administrations have worked to increase fitting of GMDSS elements
(e.g., radios incorporating DSC functions and satellite EPIRBs) on
non-SOLAS vessels, this fitting on a world-wide basis is not expected to
be completed in the foreseeable future. Therefore, the provisions in
Appendix **13** continue to be required to provide necessary guidance
(e.g., consideration of frequencies and modes of operation for their
distress and safety communications) for non-SOLAS vessels. In addition
to the guidance for non-GMDSS vessels, this Appendix includes
certification requirements for personnel operating radio equipment on
these non-GMDSS vessels. Because the majority of these vessels do not
have radio carriage requirements (other than those of national
authorities) coupled with the abandonment in many part of the world of
radiotelegraphy; certification requirements (including the ability to
send and receive Morse code) is no longer necessary.

**Proposal**:

**USA/ /1 [NOC]{.underline}**

Appendix 13

**Reasons**: Deletion of Appendix **13** is premature at this time as a
large number on non-SOLAS vessels have not yet been fitted for GMDSS.
Revisions to this appendix would be a very time consuming effort without
adequate benefit.

DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE

**Doc. WAC/138(05.09.02)**

**WRC-03 Agenda Item 1.10.1:** to consider the results of studies, and
take necessary actions, relating to exhaustion of the maritime mobile
service identity numbering resource (Resolution **344 (WRC-97))**;

**Background Information**: This agenda item addresses the potential of
an impending exhaustion of the Maritime Mobile Service Identities (MMSI)
numbering resource. Resolution **344** instructs the Radiocommunication
Bureau to monitor the status of the MMSI resource and report the status
to each WRC.

Maritime mobile service identities (MMSIs) are required for many
shipborne communications equipment (e.g. DSC, mobile earth stations).
The MMSI is a 9‑digit number to uniquely identify ship stations, group
ship stations, coast stations, and group coast stations. Three of the
nine MMSI digits are the Maritime Identification Digits (MIDs) that
represent territory or geographical area of administrations and are
assigned by the ITU. The total possible number of MMSIs is reduced by
ITU Recommendations, which advise administrations to assign MMSIs with
three trailing zeros to ships sailing worldwide and communicating with
foreign coast stations. Additionally, ITU-T Recommendation E.215 has a
requirement to assign MMSIs ending in 3-zeros to vessels requiring
access to certain satellite services. Therefore, for each MID assigned,
there are only 999 numbers available for use by ships with the present
generation of maritime mobile-satellite networks operated by Inmarsat
Ltd. (Standard B, C and M). Additional MIDs are now assigned by the ITU
to administrations when they have used 80% of the MMSIs with three
trailing zeros as documented via the notification requirements of
Article **19**. As the number of vessels carrying such systems
increased, so has the demand for MMSIs with three trailing zeros.

**Proposal**:

ARTICLE 19

Identification of stations

Section II -- Allocation of international series and assignment of call
signs

**USA/ /1 ADD**

[**19.31A** 4) Means shall be provided for identifying uniquely mobile
stations operating in automated terrestrial or satellite communication
systems for the purposes of answering distress calls, avoiding
interference and for billing. Identification of the mobile station by
accessing a registration database is satisfactory, provided that the
system can associate the mobile station radio calling number with the
particular mobile station user.]{.underline}

**Reasons**: To provide guidance that identification of mobile stations
can be provided by use of a registration database, thereby allowing use
of all 9-digits of the MMSI.

**USA/ /2 MOD**

**19.35** § 16 The Secretary‑General shall be responsible for allocating
additional maritime identification digits (MIDs) to administrations
within the limits specified[^11], provided that he is satisfied that the
possibilities offered by the MIDs allocated to an administration will
soon be exhausted despite judicious ship station identity assignment as
outlined in Section VI, which should be in conformity with the relevant
ITU‑R and ITU‑T Recommendations.

**Reasons:** The suppression of footnote 2 is consequential to **MOD**
**19.36** shown below.

USA / /3 MOD

**19.36** §17 ~~A single~~ [Each administration has been allocated one
or more]{.underline} maritime identification digit[s]{.underline} (MID)
~~has been allocated initially to each administration~~ [for its
use]{.underline}. A second [or subsequent]{.underline} MID should not be
requested[^12] unless the ~~first~~ [previously allocated]{.underline}
MID ~~allocated~~ is more than 80% exhausted in the basic category of
three trailing zeros and the rate of assignments is such that 90%
exhaustion is foreseen. ~~The same criteria should be applied to
subsequent requests for MIDs.~~

**Reasons**: Clarify the text describing requirements for requesting of
additional MIDs. This is further explained in footnote 2 (**19.36.1**).

Section VI -- Maritime mobile service identities in the maritime mobile
service and\
the maritime mobile‑satellite service

USA/ /4 MOD

**19.101** 2) These identities are formed in such a way that the
identity or part thereof can be used by telephone and telex subscribers
connected to the [public]{.underline}~~general~~ telecommunications
network principally to call ships automatically in the shore-to-ship
direction. [Access to public networks may also be achieved by means of
free form numbering plans, so long as the ship can be uniquely
identified using the systems registration database (see No. **19.31A**)
to obtain the ship station identity, call sign or ship name and
nationality.]{.underline}

**Reasons**: Allows use of free form numbering plans thereby alleviating
the requirement for use of three trailing zeros.

108. B -- Maritime identification digits (MIDs)

USA/ /5 ADD

[**19.108A**]{.underline} § [42 The maritime identification digits
M~1~I~2~D~3~ are an integral part of the maritime mobile service
identity and denotes the geographical area whose administration is
responsible for the station so identified (see Nos. **19.102** to
**19.106**).]{.underline}

**Reasons**: Provides additional definition for MIDs denoting linkage to
geographical area.

USA/ /6 SUP

~~**19.109** § 42 These provisions do not require an administration to
assign numerical identities until it determines that such identities are
necessary. They do not concern the assignment of ship station identities
without trailing zeros, since it is assumed that there is enough
capacity inherent in the system to provide for the assignment of such
identities to all ship stations which an administration may wish to
identify in this manner.~~

**Reasons**: This change is consequential to **MOD 19.31A** above.

**19.110 C -- Ship station identities**

**USA/ /7 MOD**

**19.112** *a)* follow the guidelines contained in the ~~relevant~~
[most recent version of Recommendation]{.underline} ITU-R ~~and ITU-T
Recommendations for~~[M.585 concerning]{.underline} the assignment [and
use]{.underline} of ship station identities.

**Reasons**: Gives ITU-R responsibility for management of MMSI and MID
resources.

**USA/ / 8 MOD**

**19.114** *c)* take particular care in assigning ship station
identities with six significant digits (three-trailing-zero identities),
which should be assigned only to ship stations which can reasonably be
expected to require such an identity for automatic access on a
world-wide basis for public switched networks~~;~~[, in particular for
mobile satellite systems accepted for use in GMDSS on or before 1
February 2002, as long as those systems maintain the MMSI as part of
their numbering scheme.]{.underline}

**Reasons**: Clarification that MMSI with three trailing zeros is
applicable primarily for earlier mobile satellite systems.

**USA/ / 9 SUP**

**19.115** *d)* ~~assign one‑trailing‑zero or two‑trailing‑zero
identities to vessels when they require automatic access only on a
national or regional level, as defined in the relevant ITU‑T
Recommendations;~~

**Reasons**: Originally, it was thought that a significant number of
vessels which sailed domestically or on a regional basis and also
required automatic access to Public Switched networks via DSC would be
able to use a regional or domestic designator (8 or 9 respectively) as
the first digit of the MMSI resulting in only two trailing zeros being
available. There are no current or planned DSC coast stations planning
to provide the automatic access, therefore, reserving MMSIs with one or
two trailing zeros for this purpose is no longer necessary, confusing
and undesirable.

**USA/ / 10 SUP**

**19.116** *e)* ~~assign ship station identities without trailing zeros
to all other vessels requiring a numerical identification.~~

**Reasons**: Since there are no longer needs for numbers ending with one
or two zeros to be reserved for automatic access to PSTN via DSC, there
are only two types of formats, those with three trailing zeros used
mainly for INMARSAT and all others therefore there is no need for the
above provision.

studies conducted in response to Resolution **127 (Rev.WRC-2000)**,
provided that due recognition is given to the passive services, taking
into account No. **5.340**;

**Background Information**: Service allocations to the little LEO MSS
were first made at WARC-92. Since 1995, additional allocations were
sought by the little LEOs for feeder links without success. **Resolution
127** (**WRC-97**) identified the bands 1 390-1 400 MHz and 1 427-1 432
MHz for studies to be carried out to accommodate up and downlinks,
respectively, provided sharing with services using these bands was
feasible and that the passive services operating in the 1 400-1 427 MHz
band can be fully protected. Subsequent to WRC-97, little LEO
requirements have been restricted to the 1 390-1 393 MHz and 1 429-1 432
MHz bands, for up and downlinks, respectively, and this narrower scope
is reflected in **Resolution 127 (Rev. WRC-2000)**. More recently, the
need for new allocations seems to have disappeared altogether. Draft
CPM-02 text, prepared by WP 8D states: \" However, during WRC-03
preparation, no evidence of spectrum congestion of MSS service links
below 1 GHz has been shown in ITU-R. Furthermore, the experience of MSS
below 1 GHz has demonstrated that the growth of the traffic could be
accommodated in the existing frequency bands without requirement for an
additional allocation. In addition, it has to be noted that several
frequency bands are already allocated in upper frequency bands (for
example 5 091‑5 250 MHz) for non-GSO MSS feeder links and could provide
an alternative solution for feeder links of MSS systems with service
links below 1 GHz.\"

The 1 400-1 427 MHz band is allocated on a primary, exclusive basis to
the passive services, worldwide. It is arguably the most important, and
certainly the most frequently and extensively observed radio astronomy
band below 70 GHz. Observations in the band are conducted at a large
number of sites in the U.S. and worldwide, to study the distribution,
kinematics and dynamics of neutral hydrogen (the most commonly occurring
element in the Universe) in our own as well as in other galaxies. Ocean
and soil salinity and other measurements are conducted in the band under
the EESS allocation. Full retention and unconstrained access to the
1 400-1 427 MHz band is considered crucial by both the radio astronomy
and EESS communities. For this reason, it is essential to conclude the
studies mandated in Resolution **127,** before an allocation can be
made.

Some theoretical work was done in SG 7 during the previous ITU-R cycle
towards showing that by using certain modulations the planned little LEO
feeder links could meet the unwanted emission level required in the band
1 400-1 427 MHz, for no impact on the operation of the passive services
in this band. Resolution **127 (WRC-2000)** invited the ITU-R, as a
matter of urgency to carry out additional studies, tests and
demonstrations, *including the measurement of emissions from equipment
that would be employed in operational systems to protect passive
services in the band 1 400- 1427 MHz from unwanted emissions from feeder
links near 1.4 GHz* for non-GSO systems with service links operating
below 1 GHz. However, no such work has been initiated in any of the
ITU-R study groups during the present cycle. There has been a complete
lack of new studies undertaken or even known to be in progress,
particularly towards *invites 3* of Resolution **127**: \"to carry out
additional studies *including the measurement of emissions from
equipment that would be employed in operational systems to protect
passive services in the band 1 400- 1 427 MHz from unwanted emissions
from feeder links on a worldwide basis\...\"*

**Resolution 127** recommends that WRC-03 consider additional
allocations for feeder links on the basis of completed studies referred
to in its invites 1, 2 and 3. Since no such studies were conducted,
consideration of any allocation is premature and it is proposed that
**Resolution 127** be suppressed.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Doc. WAC/135(05.09.02)**

*NTIA Revision of Doc. WAC/113(04.06.02)*

**WRC Agenda Item 1.32*(Resolution 84)***: to consider technical and
regulatory provisions concerning the band 37.5-43.5 GHz, in accordance
with Resolutions **128 (Rev.WRC-2000)** and **84 (WRC‑2000)**;

**Background Information**: Various segments of the 37.5 - 43.5 GHz band
are allocated to the FS, FSS, BSS and MSS on a co-primary basis.
Segments of this band are being used or planned for high-density
applications in the FS ("HDFS"), and other segments of the band are
planned for deployment of high-density applications in the FSS
("HDFSS"). Co-frequency sharing is not feasible between HDFS and HDFSS
systems, but sharing situations where only one of the services operates
with ubiquitously deployed small terminals may be practicable.

Significant actions were taken at WRC-2000 with respect to the 37.5 -
43.5 GHz band. Among other things, WRC-2000 adopted provisional power
flux-density (pfd) limits for geostationary and non-geostationary
satellites in the fixed-satellite service (FSS), in the
broadcasting-satellite service (BSS), and in the mobile-satellite
service (MSS) in this frequency range. WRC-2000 also called for study of
the criteria and techniques to address interference from transmitters of
FS into earth station receivers in high-density applications in the FSS
in the bands 39.5 - 40.0 GHz and 40.5 -- 42.0 GHz intended to operate in
the same geographic area.

The ITU-R has now completed its study of the provisional pfd limits
adopted for satellites of the FSS, BSS, and MSS in the 37.5-42.5 GHz
range, and has concluded that in the 37.5 - 42.0 GHz range the
provisional pfd limits can be confirmed at their current values. In so
doing, the ITU-R noted the position of some Region 2 administrations
that, to protect certain sensitive FS links in the 37.5-40 GHz band, it
would be necessary for a GSO FSS satellite providing service on their
territory to reduce the pfd levels that are produced during clear-sky
operation by 12 dB from the respective levels in Table 21-4 of Article
21. The ITU-R also acknowledged that these pfds may constrain the FSS to
the use of only large coordinated earth stations in this band.
Nevertheless, for both GSO and non-GSO FSS satellites, the ITU-R
concluded that it was appropriate to maintain the pfd values in Table
21-4 of Article 21[, with the exception of the 42.0 - 42.5 GHz band. The
ITU-R concluded that, based on current technology, it may not be
possible for NGSO FSS systems operating in the 42.0 - 42.5 GHz band to
limit their unwanted emissions to the detrimental interference level
needed to protect single dish radio astronomy observations in the in the
42.5 - 43.5 GHz band \[-137 dB (W/m^2^/1GHz) for continuum observation
and -153 dB(W/m^2^/500 kHz) for spectral line observations\]. It is
proposed to remove the FSS and BSS allocations in the 42.0 - 42.5 GHz
band, as shown in Table 21-4. It is expected that a combination of the
500 MHz guard band (42.0 - 42.5 GHz) and some restrictions on the number
of FSS antenna beams incident on the Earth's surface in the 41.5 - 42.0
GHz band will be sufficient to protect the radio astronomy service in
the 42.5 - 43.5 GHz band, as called for in Resolution
**128**.]{.underline} The confirmation of the provisional pfd limits
would provide satisfactory closure to a complex and difficult set of
issues that has been intensively studied within the ITU-R for more than
five years.

The ITU-R, however, did not complete its study of the criteria and
techniques for addressing interference from transmitters of the fixed
service into earth station receivers in high-density applications in the
bands 39.5-42 GHz and intended for operation in the same geographic
area. This aspect of Resolution **84 (WRC-2000)** formed an essential
part of the overall arrangement between the FSS and the FS in the
37.5-42.5 GHz range. Although study of the pfd-related elements of
sharing in the 37.5-42.5 GHz range has been completed and regulations on
the subject are able to be finalized at WRC-03, the ITU-R should
continue the studies called for in "Invites 6" of Resolution **84**
regarding means of addressing interference from transmitters of the FS
into earth station receivers in high-density applications in the 40-42
GHz portion of the 39.5-42 GHz band.

Proposals[^13] of the United States to implement the conclusions reached
by the ITU-R in its studies under Resolution **84**, as well to reflect
the ITU-R's identification of the area where further study still is
needed, are provided below:

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

**Reasons**: On the basis of its studies under Resolution **84
(WRC-2000)**, the ITU-R has confirmed the pfd values for FSS, MSS, and
BSS satellites in the 37.5-42.[0]{.underline}~~5~~ GHz range. As a
result, it is appropriate to remove the provisional status that was
placed on these limits by WRC-2000. [It is proposed to remove the FSS
and BSS allocations in the 42.0- 42.5 GHz band. A combination of the
500 MHz guard band (42.0 - 42.5 GHz) and some restrictions on the number
of FSS antenna beams incident on the Earth's surface in the 41.5 - 42.0
GHz band is expected to be sufficient to protect the radio astronomy
service in the 42.5 - 43.5 GHz band, called for in Resolution
**128**.]{.underline}

**5.551AA** ~~In the bands 37.5-40 GHz and 42-42.5 GHz,
non-geostationary-satellite systems in the fixed-satellite service
should employ power control or other methods of downlink fade
compensation of the order of 10 dB, such that the satellite
transmissions are at power levels required to meet the desired link
performance while reducing the level of interference to the fixed
service. The use of downlink fade compensation methods are under study
by the ITU-R (see Resolution **84** **(WRC-2000)**).  (WRC‑2000)~~[In
the bands 37.5-40 GHz and 40.5-42 GHz, the power flux-density at the
Earth's surface from any FSS space station should be at the level(s)
required to meet the FSS link availability and performance objectives of
the subject applications, but no greater than the relevant power
flux-density limits in Table **21-4**, while addressing the sharing
conditions with the fixed service. (WRC-03)]{.underline}

**Reasons**: Even with the confirmation of the provisional pfd levels
pursuant to ITU-R studies under Resolution **84** **(WRC-2000)**, it is
important to the sharing conditions with the FS that the satellite pfds
be only at the level required to meet link availability and performance
objectives.

RESOLUTION BSA (WRC-~~20~~03)

Means to address interference from transmitters of the fixed service
into earth station receivers in high‑density applications in the FSS
having allocations in the band 40-42 GHz and intended for operation in
the same geographic area

The World Radiocommunication Conference ~~(Caracas, 2003)~~ (Geneva,
2003),

considering

*a)* that this Conference has established power flux-density (pfd)
limits for the fixed‑satellite service (FSS) (space-to-Earth) in the
bands 37.5-40.0 GHz and 40.5-42.[0]{.underline}~~5~~ GHz, and the
mobile‑satellite service (MSS) (space-to-Earth) in the band 39.5-40 GHz;

*b)* that, in the band 37.5-42.5 GHz, Recommendation ITU-R SF.1484-1
recommends maximum pfd levels for non-geostationary (non-GSO) FSS
satellites and Recommendation ITU-R SF.\[4-9S/BL/3\] recommends maximum
pfd levels for geostationary (GSO) FSS satellites;

*c)* that, although sharing is feasible between FSS earth stations and
terrestrial stations provided that appropriate coordination procedures
and/or operational techniques are employed, sharing may in practice
become difficult when high geographic densities of such stations are
deployed in bands heavily used by either service;

*d)* that, within the range 40-4[1.5]{.underline}~~2~~ GHz, many
administrations plan to deploy FSS systems using ubiquitous very small
aperture terminals;

*e)* that WRC-2000 invited the ITU-R to undertake, as a matter of
urgency, studies on the appropriate criteria and techniques for
addressing interference from transmitters of the fixed service into
earth station receivers in high‑density applications in the FSS having
allocations in the bands 39.5-40 GHz and 40.5-42 GHz and intended for
operation in the same geographic area;

*f)* that the ITU-R has not yet completed the studies described in
*considering e)* above;

> resolves to invite the ITU-R

1 to undertake, as a matter of urgency, studies on the appropriate
criteria and techniques for addressing interference from transmitters of
the fixed service into earth station receivers in high‑density
applications in the FSS having allocations in the band
40-4[1.5]{.underline}~~2~~ GHz and intended for operation in the same
geographic area;

2 to report on the results of these studies in time for WRC-06,

> recommends

that WRC-06 take appropriate action based on the results of these
studies.

**Reasons:** Work was not completed on *invites 6* from WRC-2000
Resolution **84**. This is important work in the overall sharing
arrangements for FSS and FS in the 37.5-42.[0]{.underline}~~5~~ GHz
frequency range, and should be completed within the interval between
WRC-03 and WRC-06. The band under consideration for these studies should
be concentrated on the 40-42 GHz band.

RESOLUTION 84 (WRC-2000)

Power flux-density limits in the bands 37.5-42.5 GHz for the
fixed-satellite service, broadcasting-satellite service and
mobile-satellite service

**Reasons**: Consequential to the confirmation of the power flux-density
levels within the 37.5-42.[0]{.underline}~~5~~ GHz band pursuant to
ITU-R study, and the capture in new Resolution BSA of the holdover point
from invites 6 of Resolution **84 (WRC-2000)**.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Doc. WAC/135(05.09.02)**

*NTIA counter proposal to Doc. WAC/114(04.06.02)*

**Agenda Item 1.32a *(Resolution 128)***: to consider technical and
regulatory provisions concerning the band 37.5-43.5 GHz, in accordance
with Resolutions **128 (Rev.WRC-2000)** and **84 (WRC‑2000);**

**Background Information:** The band 42.5 - 43.5 GHz is allocated to the
Radio Astronomy (RA) service on a co-primary basis, while the frequency
bands immediately below 42.5 GHz are allocated to the FSS and BSS (both
space-to-Earth) on a co-primary basis with each other and with
terrestrial services. Prior to WRC--2000, Resolution 128 prevented
administrations from implementing the fixed-satellite service in the
41.5--42.5 GHz band until the Radiocommunication Bureau could identify
and agree to technical and operational measures to protect radio
astronomy operations in the 42.5--43.5 GHz. WRC--2000 modified
Resolution 128 and added a footnote to the Table of Frequency
Allocations (No. 5.551G) to protect radio astronomy stations. The
footnote contains a provisional PFD limit - not to exceed -167
dB(W/m^2^) in any 1 MHz band at the site of a radio astronomy station
for more than 2% of the time - on emissions produced into the 42.5 -
43.5 GHz band by non-GSO FSS or BSS systems operating in the 41.5 - 42.5
GHz band. A similar limit was imposed on emissions that GSO FSS or BSS
satellites operating in the 42.0 - 42.5 GHz band may produce at the
sites of RA stations operating in the 42.5 - 43.5 GHz band.

Pursuant to Resolution **128 (Rev. WRC-2000)**, the ITU-R was to conduct
studies to review these provisional PFD limits; to identify technical
and operational measures in the band 41.5 -- 42.5 GHz, including
possible mitigation techniques to protect RA operations; and to propose
measures that may be implemented to reduce the susceptibility of
stations in the RA to harmful interference. Issues to be addressed
included:

-   Adequacy of provisional limits on power flux-density (PFD) produced
    into the sites of radio astronomy service (RAS) stations operating
    in the band 42.5 - 43.5 GHz by non-GSO satellites operating in the
    space-to-Earth direction in the fixed-satellite service (FSS) or
    broadcasting-satellite service (BSS) in the band 41.5 - 42.5 GHz,
    and by GSO FSS or BSS satellites operating in the space-to-Earth
    direction in the band 42.0 - 42.5 GHz.

```{=html}
<!-- -->
```
-   Identification of technical and operational measures that FSS/BSS
    satellite networks can take to protect RA operations in the 42.5 -
    43.5 GHz band, including geographical separation and out-of-band
    emission limits to be applied to BSS and FSS space stations, and of
    measures that may be implemented by RA service users to reduce the
    susceptibility of stations in the RA service to harmful
    interference.

Results of studies indicate that the unwanted emission levels of the GSO
FSS and BSS systems operating in the 42.0-42.5 GHz band meet the
detrimental interference threshold for VLBI RAS stations operating in
the 42.5-43.5 GHz band. As a rule, VLBI observations are conducted at
most single dish telescopes for a fraction of the time, except for one
dedicated VLBI instrument worldwide. The detrimental interference
threshold for a single dish telescope, -137 dB (W/m^2^/1GHz) for
continuum observation and -153 dB(W/m2/500 kHz) for spectral line
observation, may not be met by a GSO FSS or BSS system by implementing
transmit filters, because based on current technology, it is difficult
to design and implement such filter.

It is expected that a combination of a 500 MHz guard band (42.0 - 42.5
GHz) between the space services and radio astronomy allocations along
with some restrictions on the number of satellite antenna beams incident
on the Earth's surface for the fixed-satellite service allocation in the
41.5 - 42.0 GHz band will be sufficient to protect the radio astronomy
service in the 42.5 - 43.5 GHz band.

The proposal described herein removes the fixed-satellite service
(space-to-Earth) and broadcasting-satellite service allocations from the
42--42.5 GHz frequency band. The limits on the power flux-density of
space services emissions in the radio astronomy band, have been relaxed
somewhat, by adopting as detrimental threshold level, the spectral line
power flux density in the 500 kHz reference bandwidth used for spectral
line observations in this band (see Table 2 of Recommendation ITU-R
RA.769). Footnote RR 5.551G, as provisionally adopted by WRC-2000
combined the more restrictive continuum pfd threshold level with a 1 MHz
reference bandwidth. The proposal also limits the fixed-satellite
service use of the 41.5--42 GHz band to \[gateway\] links and subjects
geostationary systems to the relaxed PFD limits in that sub-band.

**Reasons**: The proposal establishes a 500 MHz guard band between the
space services and radio astronomy allocations. The guard band should
contribute significantly towards the meeting the detrimental
interference level to reduce the level of unwanted space services
emissions in the radio astronomy band.

**USA/ / MOD**

**5.551AA** ~~In the bands 37.5-40 GHz and 42-42.5 GHz,
non-geostationary-satellite systems in the fixed-satellite service
should employ power control or other methods of downlink fade
compensation of the order of 10 dB, such that the satellite
transmissions are at power levels required to meet the desired link
performance while reducing the level of interference to the fixed
service. The use of downlink fade compensation methods are under study
by the ITU-R (see Resolution **84** **(WRC-2000)**).  (WRC‑2000)~~[In
the bands 37.5-40 GHz and 40.5-42 GHz, the power flux-density at the
Earth's surface from any FSS space station should be at the level(s)
required to meet the FSS link availability and performance objectives of
the subject applications, but no greater than the relevant power
flux-density limits in Table **21-4**, while addressing the sharing
conditions with the fixed service. (WRC-03)]{.underline}

**Reasons:** This modification is consequential to the allocation
change.

5.551G In order to protect the radio astronomy service ~~in the band
42.5-43.5 GHz~~, the aggregate power flux-density in the 42.5-43.5 GHz
band produced by all the space stations in any
non-geostationary-satellite system in the fixed-satellite service
(space-to-Earth) or in the broadcasting-satellite service
(space-to-Earth) system operating in the 41.5-42~~.5~~ GHz band shall
not exceed [- 137 dB(W/m^2^) in the 42.5 -43.5 GHz band and]{.underline}
~~--167~~ [153]{.underline} dB(W/m^2^) in any ~~1 MHz~~ [500 kHz
sub]{.underline}band at the site of a radio astronomy station for more
that 2% of the time. The power flux-density in the band 42.5-43.5 GHz
produced by any geostationary station in the fixed-satellite service
(space-to-Earth) or in the broadcasting-satellite service
(space-to-Earth) operating in the band [41.5--]{.underline}42~~--42.5~~
GHz shall not exceed [- 137 dB(W/m^2^) in the 42.5 -43.5 GHz band and
--153]{.underline} ~~--167 ~~ dB(W/m^2^) in any ~~1 MHz~~ [500 kHz

limits are provisional and will be reviewed in accordance with
Resolution 128 (Rev.WRC-2000).~~     (WRC‑~~20~~0[3]{.underline})

**Reasons**: This modification reflects the deletion of the FSS and BSS
from the 42.0 - 42.5 GHz band. The limits on the power flux-density of
unwanted emissions by space services emissions operating in the 41.5 -
42.0 GHz band into the 42.5 - 43.5 GHz radio astronomy band have been
relaxed somewhat, by adopting as detrimental threshold levels the
continuum detrimental threshold level in the full 1 GHz band and the
spectral line power flux density in the 500 kHz reference bandwidth used
for spectral line observations in this band (see Table 2 of
Recommendation ITU-R RA.769). Footnote RR 5.551G, as provisionally
adopted by WRC-2000 combined the more restrictive continuum pfd
threshold level with a 1 MHz reference bandwidth. The proposal also
subjects geostationary systems operating in that sub-band to the same
relaxed PFD limit.

**5.551x** The band 41.5--42 GHz is not available for HDFSS
applications. Use of the band by the fixed-satellite service

limit the number of satellite antenna beams that could cause
interference to radio astronomy receiver locations.

**Reasons**: Consequential to the conclusion that RAS operations in the
42.5 - 43.5 GHz band can be adequately protected from unwanted emissions
from FSS and BSS satellite systems operating in the 41.5 - 42 GHz band

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Doc. WAC/137(05.09.02)**

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 801 (WRC-2000);

Resolution 801 (WRC-2000), Agenda Item 2.12: to consider spectrum
requirements for wideband aeronautical telemetry in the band between 3
GHz and 30 GHz;

**Background Information**: The World Radiocommunication Conference 2000
included item 2.12 in the preliminary agenda for the World
Radiocommunication Conference 05/06. The 2000 Radiocommunication
Assembly approved Question ITU-R 231/8, titled: *Operation of wideband
aeronautical telemetry in bands above 3 GHz*. The 2000
Radiocommunication Assembly directed that Question ITU‑R 231/8 studies
be completed by 2005. ITU-R Circular letter CA/109 requested
administrations and Sector Members to supply data on existing and
planned wideband aeronautical telemetry systems operating at frequencies
above 3 GHz. In this circular letter Wideband Aeronautical Telemetry is
defined as: *Emerging Telemetry Systems With Large Data Transfer
Requirements to Support New and Different Telemetry Capabilities (such
as high resolution video and associated data for remotely-piloted
aeronautical vehicles). It is further defined as telemetry generally
requiring a bandwidth of 20 MHz or greater.*

The wideband requirements addressed under this WRC-06 proposal are in
addition to those presently operating in the existing aeronautical
telemetry allocations below 3 GHz (in the 1 429-1 525 and 2 300-2 390
MHz bands.) The requirement for these allocations will continue. Rather,
the allocation addressed in this proposal is for new wideband
requirements.

The responses to ITU-R Circular letter CA/109 indicated that there are
requirements for additional telemetry spectrum, up to 300 MHz
contiguous, for wideband aeronautical telemetry. There has been a trend
toward cooperation and multi-platform testing that is leading to a need
for identification of additional harmonized band(s) for aeronautical
telemetry. As airframe speed, missions, and technology increase there is
an expanding need for new and more numerous telemetry points for
real-time testing of aircraft to ensure each platform is rigorously
tested and evaluated to ensure safety on these high technology
platforms. Many Administrations now utilize advanced telemetry testing
involving multiple platforms in complex environments that call for
cooperation of more than one country. By designating a harmonized
wideband aeronautical telemetry band between 3 and 30 GHz, the needs for
this type of testing can be met.

RESOLUTION 801 (WRC-2003)

[A]{.underline}~~a~~genda for the ~~2005/~~2006 World Radiocommunication
Conference

The World Radiocommunication Conference ~~(Istanbul, 2000),~~ [(Geneva,
2003),]{.underline}

**Reasons**: Editorial

*resolves to give the view*

##### USA/ / 2 NOC {#usa-2-noc .unnumbered}

2.12 To consider spectrum requirements for wideband aeronautical
telemetry in the band between 3 and 30 GHz.

**Reasons**: To provide an agenda item to study spectrum requirements
for wideband aeronautical telemetry.

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

**Doc. WAC/138(05.09.02)**

######  {#section-1 .unnumbered}

###### *Proposal for Resolution 801, Agenda Item 3.1* {#proposal-for-resolution-801-agenda-item-3.1 .unnumbered}

**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 **801 (WRC-2000)**;

**Background Information**: Working Party 8B considered several studies
on the feasibility of sharing between IMT-2000 and radar systems
operated in the band 2 700-2 900 MHz. Those studies indicate sharing of
the band 2 700-2 900 MHz between IMT-2000 and aeronautical
radionavigation and meteorological radars is not feasible. Working Party
8B proposed that the draft CPM text for Chapter 7, Future Work Program,
reflect that "WRC-03 may wish to consider deletion of this agenda item
from the WRC-05/06 agenda" (8B/TEMP/103-E, 6 May 2002).

The band 2 700-2 900 MHz is used worldwide to support airport
surveillance radars in the aeronautical radionavigation service, which
is a safety service and "requires special measures to ensure their
freedom from harmful interference" in accordance with Article 4.10 of
the Radio Regulations.

The primary weather radar system used for flight planning activities
operates in the band 2 700-2 900 MHz and is often collocated at airports
worldwide, to provide accurate weather conditions for aircraft. Also,
these radars observe the presence and calculate the speed and direction
of motion of severe weather elements such as tornadoes and violent
thunderstorms. These radars provide quantitative area precipitation
measurements important to hydrologic forecasting of potential flooding.
The severe weather and motion detection capabilities offered by weather
radars contribute towards an increase in the accuracy and timeliness of
warning services.

Proposal:

##### USA/ / 1 SUP {#usa-1-sup .unnumbered}

~~3.1 to consider results of ITU-R studies on the feasibility of sharing
in the band 2 700-2 900 MHz between the aeronautical radionavigation
service, meteorological radars and the mobile service, and to take
appropriate action on this subject.~~

**Reasons**: WP8B has already determined that sharing is not feasible in
this band, therefore it is not necessary to continue this agenda item.
