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

**2003 WORLD RADIOCOMMUNICATION CONFERENCE APPROVES**

**DRAFT PROPOSALS**

On July 22, 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/126, WAC/127 and WAC/129. 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 Information Reference 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-B505. Comments should refer to specific
proposals by document number. The deadline for comments on the draft
proposals and NTIA letters is **August 16, 2002**.

**I. Informal Working Group 2: Mobile-Satellite Service including GPS**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/126(22.07.02)

**WRC-03 Agenda Item 1.16**: to consider allocations on a worldwide
basis for feeder links in bands around 1.4 GHz to the non-GSO MSS with
service links operating below 1 GHz, taking into account the results of
ITU-R studies conducted in response to Resolution 127 (Rev.WRC-2000),
provided that due recognition is given to the passive services, taking
into account No. S5.340

**Background Information**

A total of only l.525 MHz (space-to-Earth) and l.9 MHz (Earth-to-space)
are presently allocated on a worldwide primary basis to the MSS below l
GHz, and 300 kHz (Earth-to-space) is allocated for land MSS on a
worldwide primary basis. These allocations are for both the MSS service
links and MSS feeder links. Since these allocations were made at WARC-92
and WRC-95, the Radiocommunication Bureau has identified 25 non-GSO MSS
networks at frequencies below l GHz at some state of coordination and 9
non-GSO MSS networks at the advance publication stage only. Yet it
appears that many of the proposed networks cannot be implemented in the
existing allocations, because there is not enough spectrum readily
available in the allocated spectrum bands. Additional feeder link
spectrum outside of the currently allocated bands would provide
dedicated feeder link spectrum and free up existing allocations for
scarce service link spectrum.

WRC-97 approved Resolution 127 to study sharing techniques for NVNG MSS
\< 1 GHz feeder links (Earth-to-space) in the 1390-1400 MHz band and
space-to-Earth feeder links in the 1427-1432 MHz band. Sharing studies
completed in the ITU-R under Resolution 127 with respect to the proposed
allocation of spectrum for space-to-Earth feeder links (1429-1432 MHz)
include: (a) protection of the radioastronomy service by controlling
out-of-band emissions to meet Recommendation RA.769-1 levels of -255 dB
(W/m^2^/Hz) for the 1400-1427 MHz band; (b) protection of EESS by
meeting Recommendation SA. 1029-1 requirements of -171 dBW/27MHz for
in-band pfd levels; and (c) sharing with fixed and mobile services on
the basis of not exceeding the pfd levels established for sharing in the
adjacent bands of -146 dBW/m^2^/4 kHz (since no level had been
established for the 1429-1432 MHz band). Sharing studies that have been
completed with respect to the proposed allocation of spectrum for
Earth-to-space feeder links include:

\(a\) protection of EESS by meeting Recommendation SA.1029-1
requirements of -171 dBW/27MHz for in-band pfd levels; and (b) sharing
with the radiolocation service by equipping the non-GSO MSS satellites
with adequate filtering. Protection of the radioastronomy service at
nearby frequencies can be achieved by geographic separation of MSS
uplinks from radioastronomy sites. In addition, sharing with the fixed,
mobile, and passive services will be dependent on the characteristics of
the respective services.

As a result of the favorable initial studies in these bands, WRC-00
placed on the proposed agenda for WRC-03 (subsequently approved by the
ITU Council) Agenda Item 1.16, to consider allocations at 1390-1393 MHz
for Earth-to-space feeder links and 1429-1432 MHz for space-to-Earth
feeder links for the non-GSO MSS service with the understanding that
Resolution 127 studies would be completed including testing of
near-flight hardware to validate the theoretical studies approved
earlier.

The U.S. proposes allocations in the 1390-1393 MHz (Earth-to-space) and
1429-1432 MHz (space-to-Earth) bands at WRC-03 for non-GSO MSS feeder
links. The proposed allocations are in bands close to the passive
services band at 1400-1427 MHz that must be protected from out-of-band
and spurious emissions. Studies have shown that interference to radio
astronomy and the other passive services can be avoided using various
techniques including low-power transmitter levels, choice of modulation,
symbol shaping, output filtering and band limiting filters, the use of
which can minimize the band separation necessary to meet the recommended
interference threshold levels for protection of these services. The U.S.
expects that the hardware testing to be completed before WRC-03 will
confirm the theoretical results already approved by the ITU-R for the
protection of the passive services. The U.S. proposal for allocation of
these bands to NGSO MSS feeder links follows.

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

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Doc. WAC/087rev1(22.07.02)**

**WRC-03 Agenda Item 1.25**: to consider, with a view to global
harmonization to the greatest extent possible, having due regard to not
constraining the development of other services, and in particular of the
fixed service and the broadcasting-satellite service, regulatory
provisions and possible identification of spectrum for high-density
systems in the fixed-satellite service above 17.3 GHz, focusing
particularly on frequency bands above 19.7 GHz

**Background Information:**

The demand for broadband services is increasing. Market research
predicts substantial growth in demand for broadband multi-media access,
both for residential and business applications. Satellite systems offer
an attractive competitive alternative to terrestrial communication
systems for providing such access.

High-density systems in the fixed-satellite service (HDFSS systems) may
use any orbital type (GSO or non-GSO) consistent with the FSS
allocation. As envisioned in technical and operational studies, HDFSS
systems incorporate small, ubiquitous, low-cost earth stations that can
be deployed rapidly and flexibly. As a consequence of these general
characteristics, it is not practicable to coordinate HDFSS earth
stations with terrestrial services on an individual, site-by-site basis.

While sharing between Fixed Service (FS) stations and non-ubiquitous FSS
earth stations can typically be handled through proven case-by-case
coordination procedures, the most effective use of the spectrum within a
given country where high-density deployments of FSS stations are
involved may be achieved by deploying HDFSS and FS systems separately.
This enables both types of systems to provide the most efficient, least
constrained, highest quality and lowest cost service to the greatest
number of users.

Effective HDFSS earth station deployment is very difficult to achieve
when site-by-site coordination between FS stations and HDFSS earth
stations is required. Therefore, it is appropriate for administrations
to authorize HDFSS earth stations under a regime whereby a large number
of earth stations can be deployed without the need for individual earth
station site coordination. Such authorization would not relieve an HDFSS
network from the ITU requirements to coordinate with fixed service
networks on a site-by-site basis, where required, across international
borders, nor would it preclude coordination of specific earth stations
within HDFSS deployments with fixed service networks.

A number of FSS systems with other characteristics, and with earth
stations of types other than those used by HDFSS systems, have already
been brought into use, or are planned to be brought into use, including
some that use the 17.8--21.2 GHz (space-to-Earth) frequency band.
Accordingly, it is essential that existing FSS allocations be retained
and that non-HDFSS use of these FSS allocations not be subject to
additional regulatory constraints in the Radio Regulations as a result
of the HDFSS band identification. Further, identification of spectrum
for HDFSS does not relieve an HDFSS network of the ITU requirement to
coordinate with other satellite networks.

**Consideration of candidate frequency bands for HDFSS identification**

A number of frequency bands allocated to the fixed-satellite service are
seen as good candidates for HDFSS identification. The 29.5--30.0 GHz and
19.7--20.2 GHz bands are allocated globally to the FSS in the
Earth-to-space and space-to-Earth directions, respectively. Since there
are no co-primary fixed service allocations in the ITU Table of
Frequency Allocations in these bands, a major sharing issue is avoided.

The 28.6--29.1 GHz and 18.8--19.3 GHz frequency bands are allocated
globally to the FSS in the Earth-to-space and space-to-Earth directions,
respectively. These are the only bands considered for HDFSS where NGSO
FSS systems are not subject to No. **S22.2** of the Radio Regulations,
and therefore represent the best opportunity for ubiquitously deployed
NGSO FSS user terminals. In these two bands, some administrations in all
Regions have planned for HDFSS and have adopted regulatory provisions
for terrestrial systems in order to facilitate HDFSS. Some HDFSS systems
are already in development in these bands and there are other filings
for HDFSS-type systems.

Many administrations are also planning to use the 18.58--18.8 GHz
(space-to-Earth) band and the 28.35--28.6 GHz and 29.25--29.5 GHz
(Earth-to-space) bands for HDFSS applications. In the 18.6-18.8 GHz
band, the FSS allocation is co-primary with the Earth
exploration-satellite service (passive) with restrictions on power and
orbit types as described in **S5.522A** and **S5.522B**.

Between 37.5 and 50.2 GHz, many administrations have submitted ITU
filings for FSS systems in the 40.0--42.0 GHz (space-to-Earth) and
48.2--50.2 GHz (Earth-to-space) bands and propose to use these bands for
global HDFSS. WRC-2000 advised administrations that may be contemplating
the use of the 40.5--42 GHz band for high-density applications in the
fixed service (HDFS) to take into account constraints to HDFS due to the
potential deployment of high-density applications in the FSS. Further,
Resolution 84 (WRC--2000) urges administrations considering regulatory
provisions relating to the 40.0--40.5 GHz band to take into account that
there were a number of proposals to WRC--2000 to identify the band for
HDFSS applications.

It is inappropriate to add or remove any fixed-satellite service
allocations in the Table of Frequency Allocations under WRC--03 agenda
item 1.25. This includes new FSS allocations in bands in which the
fixed-satellite service is already allocated in another direction. In
particular, new space-to-Earth FSS allocations in the 17.3--17.7 GHz,
21.4--22 GHz and 47.2--50.2 GHz bands, which have been discussed in
working party meetings, should be rejected. Studies have shown that the
latter band is not suitable for space-to-Earth links because of likely
interference with both FSS gateway and HDFSS uplinks.

**Description of proposal**

This proposal identifies spectrum above 18.58 GHz for high-density
systems in the fixed-satellite service without constraining the use of
these bands by other FSS applications or other co-primary services. It
specifically does not establish priority among the different uses of
these bands. The proposal consists of a new footnote **S5.\[HDFSS\]** to
frequency bands identified for high-density FSS systems, consequential
modifications to existing footnote **S5.547**, and a new
Resolution \[HDFSS\] providing guidance to administrations wishing to
amend their national rules to implement high-density systems in the
fixed-satellite service.

**Reasons**:

1.  Consequential: see reasons associated with USA/xx/2 and USA/xx/3.

2.  Studies have shown that HDFSS uplinks and HDFSS downlinks cannot
    share the same spectrum, and there are interference concerns about
    FSS gateway uplinks and HDFSS downlinks. Accordingly, it is proposed
    that there be no change to the FSS allocation directions in the
    47.2-50.2 GHz band. The FSS allocation in this band is to be
    retained for uplink use only.

**S5.\[HDFSS\]** The space-to-Earth fixed-satellite service bands
18.58-18.8 GHz, 18.8-19.3 GHz, 19.7-20.2 GHz, and 40.0-42.0 GHz and the
Earth-to-space fixed-satellite service bands 28.35-28.6 GHz, 28.6-29.1
GHz, 29.25-29.5 GHz, 29.5-30.0 GHz and 48.2-50.2 GHz, are identified for
use by high-density applications in the fixed-satellite service (HDFSS)
in accordance with **Resolution** **\[HDFSS\] (WRC-03)**. This
identification does not preclude the use of these bands by other
fixed-satellite service applications or by other co-primary services
allocated in these bands and does not establish priority among users of
the bands in the Radio Regulations.

**Reasons**: The identification of appropriate frequency bands for
high-density applications in the fixed-satellite service can help
administrations and HDFSS satellite system operators in deployment of
HDFSS earth stations. This footnote will also inform administrations of
those specific bands intended for deployment of HDFSS systems in all
regions of the world, while specifying that the use of these bands for
HDFSS applications does not preclude their use by other co-primary
services or by other FSS applications.

applications in the fixed service (see Resolutions **75** **(WRC-2000)**
and **79** **(WRC‑2000)**). Administrations should take this into
account when considering regulatory provisions in relation to these
bands. [Because the band 40.5-42 GHz is identified for use by
high-density applications in the fixed satellite service (see **No.
S5.\[HDFSS\]** and Resolution **\[HDFSS\] (WRC-03)**), and thus is
available for these applications,]{.underline} ~~Because of the
potential deployment of high-density applications in the fixed-satellite

Resolution **84** **(WRC‑2000)**)\].

**Reasons**: Consequential to the addition of No. S5.\[HDFSS\] to the

HDFSS use. *NOTE: The square brackets reflect that the fate of

**RESOLUTION \[HDFSS\] (WRC-03)**

High-Density Applications in the Fixed Satellite Service in Frequency
Bands Identified for HDFSS

The World Radiocommunication Conference (Geneva, 2003),

considering

a)  that demand has been increasing steadily for broadband
    communications services throughout the world;

b)  that this demand for ubiquitous broadband communications services
    can be met in part through the use of high-density applications in
    the fixed-satellite service (HDFSS);

c)  that HDFSS is an advanced broadband communications applications
    concept that enables telecommunications services to be provided on a
    flexible, wide-scale basis through standardized, relatively low-cost
    earth terminal equipment;

d)  that HDFSS will provide users with access to a wide range of
    broadband telecommunications services supported by fixed
    telecommunications networks (including the Internet) and thus will
    complement other telecommunications systems;

e)  that HDFSS offers great potential for developing countries to
    establish their telecommunications infrastructure more rapidly;

f)  that HDFSS systems are characterized by flexible, rapid deployment,
    high frequency reuse, and ubiquitous deployment of large numbers of
    earth stations employing small antennas and having common technical
    characteristics;

g)  that due to the large number and nature of terminals involved, it is
    not practicable for HDFSS earth stations to implement burdensome
    interference mitigation techniques,

noting

a)  that No. **S5.\[HDFSS\]** identifies the space-to-Earth FSS bands
    18.58-18.8 GHz, 18.8-19.3 GHz, 19.7-20.2 GHz, and 40.0-42.0 GHz and
    the Earth-to-space FSS bands 28.35-28.6 GHz, 28.6-29.1 GHz,
    29.25-29.5 GHz, 29.5-30.0 GHz and 48.2-50.2 GHz, for high-density
    applications in the fixed satellite service (HDFSS);

b)  that this identification does not preclude the use of these bands by
    other co-primary services or by other fixed-satellite service
    applications, and does not establish priority among users of the
    bands in the Radio Regulations;

c)  that in some of the bands listed in *noting a)* above, the FSS
    allocations are co‑primary with fixed and mobile service
    allocations;

d)  that in the band 18.6-18.8 GHz, the FSS allocation is co-primary
    with the Earth exploration-satellite service (passive) with the
    restrictions of **S5.522A** and **S5.522B**.

e)  that radio astronomy observations of an important spectral line are
    carried out in the 48.94-49.04 GHz portion of the 47.2-50.2 GHz
    band, and that such observations require continued protection
    wherever they occur worldwide;

f)  that a number of FSS systems with other types of earth stations and
    characteristics have already been brought into use or are planned to
    be brought into use in some of the frequency bands identified for
    HDFSS in No. **S5.\[HDFSS\]**;

g)  that HDFSS stations in these bands are expected to be deployed in
    large numbers over urban, suburban and rural areas of large
    geographical extent;

h)  that harmonized worldwide bands for HDFSS would facilitate the
    implementation of HDFSS and maximize the extent to which users in
    administrations around the world would be able to benefit from
    global access and economies of scale,

recognizing

a)  that as a consequence of their general characteristics, it is
    difficult and may be a rather long process to coordinate HDFSS earth
    stations on an individual site-by-site basis;

b)  that the single authorization of a large number of FSS earth
    stations associated with a given satellite system, without the need
    for individual site coordination, would greatly facilitate the
    ability of fixed-satellite services to reach large numbers of users
    within a geographic area;

c)  that such an authorization would minimize the administrative burden
    for administrations to individually authorize a large number of
    earth stations,

recognizing further

a)  that FSS networks and systems implementing HDFSS applications are
    subject to all applicable provisions of the Radio Regulations, such
    as coordination and notification pursuant to Articles **S9** and
    **S11**, including any ITU requirements to coordinate with fixed
    service networks across international borders, and the provisions of
    Articles **S21** and **S22**;

b)  that Article **S21** contains power flux density limits that protect
    fixed service receivers operating on a co-primary basis in the
    fixed-satellite service space-to-Earth bands identified in No.
    **S5.\[HDFSS\]**, thereby ensuring that transmissions from
    fixed-satellite service satellites will not cause unacceptable
    interference to fixed service receivers operating in these same
    bands;

> resolves

to urge administrations implementing HDFSS in some or all of the
corresponding frequency bands in No. **S5.\[HDFSS\]** to:

> a\) consider using a single authorization for a large number of earth

>
> b\) consider taking into account the relevant technical

> Recommendations ITU-R S.524‑7 and \[doc. 4/70\]);
>
> c\) take into account that continued assignment of spectrum to or
> deployment of terrestrial stations in bands identified for HDFSS
> within the same geographical area could impede the introduction or
> development of HDFSS and reduce or eliminate the benefits that such
> applications offer;
>
> d\) ensure compatibility with, and not constrain, other existing and
> planned fixed-satellite service systems having different
> characteristics, particularly those that use the frequency band
> 17.8-21.2 GHz (space-to-Earth),

> *invites administrations*

to give due consideration to the benefits of harmonized utilization of
the spectrum for HDFSS on a global basis, taking into account the use
and planned use of these bands by all other services to which these
bands are allocated, as well as other types of fixed-satellite service
applications.

**Reasons**: Many administrations are currently in the process of
determining how to appropriately provide for HDFSS services in their
countries. Some of these administrations are looking to the ITU for
guidance on spectrum management issues concerning the FS and HDFSS and
this Resolution provides that guidance.

Issues**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Doc. WAC/127(22.07.02)**

**WRC-03 Agenda Item 1.24:** to review the usage of the band 13.75 -
14.0 GHz, in accordance with Resolution **733 (WRC-2000)**, with a view
to addressing sharing conditions;

**Background information**

Prior to WRC-2000, footnote **S5.502** contained constraints such as
e.i.r.p. and antenna size limits on fixed-satellite service earth
stations and e.i.r.p. limits on the radiolocation service. Footnote
**S5.503** contained e.i.r.p. limits on the fixed-satellite service to
protect the space research service. These constraints were intended to
accommodate a delicate sharing of the band among these services. These
constraints were developed based upon agreements reached at WARC-92 and
applied to subsequent sharing studies on the planned use of 13.75-14.0
GHz by geostationary satellites in the FSS, and were intended to limit
the number of FSS earth stations to the point that sharing could occur,
though a potential for interference from the limited number of earth
stations would still exist. Since the time that the regulatory
constraints were developed, GSO FSS operators have expressed interest in
operating small earth stations. This is due to the increased requirement
for broadband data services delivered to businesses, hospitals, schools,
etc., in both rural and urban areas. Radiolocation operators have
expressed interest in using higher than currently allowed e.i.r.p.
values. WRC-2000 modified footnotes **S5.502** and **S5.503** to
include:

-   within footnote S5.502 that the protection of the receiving space
    stations in the FSS operating with earth stations that,
    individually, have an e.i.r.p. of less than 68 dBW shall not impose
    constraints on the operation of the radiolocation and
    radionavigation stations operating in accordance with the Radio
    Regulations.

```{=html}
<!-- -->
```
-   within footnote S5.503 that the e.i.r.p. density of emissions from
    any earth station in the FSS operating with a space station in the
    geostationary satellite orbit shall not exceed 71 dBW in the band
    13.772 to 13.778 GHz until those geostationary space stations in the
    space research service for which information for advance publication
    has been received by the Bureau prior to 31 January 1992 cease to
    operate in this band; that the e.i.r.p. density of emissions from
    any earth station in the FSS operating with a space station in
    non-geostationary satellite orbit shall not exceed 51 dBW in the
    band 13.772 to 13.778 GHz until those geostationary space stations
    in the space research service for which information for advance
    publication has been received by the Bureau prior to 31 January 1992
    cease to operate in this band.

Resolution **733 (WRC-2000)** invites the ITU-R "to conduct studies, as
a matter of urgency and in time for consideration by WRC-03, on the
sharing conditions indicated in Nos. **5.502** and **5.503**, with a
view to reviewing the constraints in No. **5.502** regarding the minimum
antenna diameter of GSO FSS earth stations and the constraints on the
e.i.r.p of the radiolocation service and to identify and study, in time
for consideration by WRC-03, possible alternative sharing conditions to
those indicated in Nos. **5.502** and **5.503**."

A joint decision of Study Groups 4, 7 and 8 (Document CVC-11/9, dated 8
June 2000) established Joint Task Group 4-7-8 to carry out the studies
under Resolution **733** on the sharing conditions in footnotes
**S5.502** and **S5.503** with a view to review the minimum antenna
diameter of GSO FSS Earth station's and the e.i.r.p. constraints of the
radiolocation service.

Within this Joint Task Group, studies have been carried out to determine
the constraints that would enable fixed-satellite service earth stations
with antenna diameters less than 4.5 meters to share with the shipborne
radars. The studies have shown that locating fixed-satellite service
earth stations a certain distance in-land will greatly minimize the
interference into shipborne radars. These studies have also determined a
power flux-density level produced by an earth station at a certain
location will protect shipborne and land radars. A study determined the
levels of off -axis e.i.r.p. density that will protect airborne radars.
With respect to sharing between FSS earth stations and space research
service systems, the studies have identified maximum on-axis e.i.r.p.
density levels that will protect the space research service systems. All
of these constraints will enable fixed-satellite service earth stations
to share with shipborne, airborne and land-based radars and space
research service systems while allowing the FSS to deploy antennas with
diameters smaller than 4.5 meters. As such, it is appropriate to modify
footnote 5.502 to remove the antenna diameter limitation and specify the
constraints on the fixed-satellite service. These studies have led to
Option A below.

It is noted that the radiolocation allocation in the band 13.75 - 14.0
GHz is part of a larger allocation that spans from 13.4 - 14.0 GHz.
Several input documents into the JTG are based on the scenario where
there are six ships operating in the same general area. Each ship is
equipped with two radar systems, and each system operates over a 10 MHz
bandwidth, resulting in a total occupied bandwidth of 120 MHz. This
information has led to Option B below.

Proposals:

[OPTION A:]{.underline}

USA/1.24/A1

**5.502** In the band 13.75-14 GHz, an earth station [of a
non-geostationary]{.underline} ~~in the~~ fixed-satellite service
[network]{.underline} shall have a minimum antenna diameter of 4.5 m
~~and the e.i.r.p. of any emission should be at least 68 dBW and should
not exceed 85 dBW~~. In addition the e.i.r.p., averaged over one second,

Regulations. No. 5.43A does not apply. See Resolution 733
(WRC‑2000).~~   [An administration planning to use FSS earth stations

[- 114.7 dBW/m^2^/10 MHz not to be exceeded for more than 0.1% of the

[These limits do not apply to FSS earth stations brought in service
prior to 4 July 2003. The power flux-density produced by an FSS earth
station shall be calculated in accordance with Resolution
**ZZZ.**]{.underline}

**Reason**: This modification to the footnote will allow for the
operation of FSS earth stations with antenna diameters smaller than 4.5
meters while protecting shipborne and land-mobile radar systems.
Resolution ZZZ will provide a methodology for Administrations to
calculate the power flux-density levels from a given FSS earth station
and will also address additional mitigation techniques that may be
necessary for FSS earth stations located close to either the baseline or
a border.

**USA/1.24/A2**

**MOD 5.503:** In the band 13.75 - 14 GHz, geostationary space stations
in the space research service for which information for advance
publication has been received by the Bureau prior to 31 January 1992
shall operate on an equal basis with stations in the fixed-satellite
service; after that date, new geostationary space stations in the space
research service will operate on a secondary basis. Until those
geostationary space station in the space research service for which
information for advance publication has been received by the Bureau
prior to 31 January 1992 cease to operate in this band:

> \- the e.i.r.p. density of emissions from any earth station in the
> fixed-satellite service operating with a space station in
> geostationary-satellite orbit [shall comply with Section VII of
> Article 22]{.underline} ~~not exceed 71 dBW~~ in the 6 MHz band from

> \- the e.i.r.p. density of emissions from any earth station in the
> fixed-satellite service operating with a space station in
> non-geostationary-satellite orbit shall not exceed 51 dBW in the 6 MHz
> band from 13.772 - 13.778 GHz.

**Reason:** This modification provides a satisfactory solution to the
sharing situation between the fixed-satellite service and the space
research service in the band 13.772 - 13.778 GHz. This will allow for
the use of smaller antenna diameter earth stations in the
fixed-satellite service without impacting the space research service
operations. Since the studies have shown that the on-axis e.i.r.p.
density limitations vary for different antenna sizes, it is best to put
the new limits in a new section of Article 22. An alternative approach,
where the limits are defined as an equation based on antenna diameter,
is to add the equation to the footnote.

**Methodology for calculating the power flux-density at Radiolocation
stations located at the baseline**[^1] **or at the border of an
Administration produced by GSO FSS Earth stations in the 13.75-14 GHz
band**

The World Radiocommunication Conference (Geneva, 2003),

*considering*

a\) that WARC-92 (Malaga-Torremolinos, 1992) added a primary allocation
to the fixed-satellite service (Earth-to-space) in the 13.75 - 14.0 GHz
band;

b\) that this band is also allocated on a primary basis to the
radiolocation service;

c\) that, in some countries, the band is also allocated to the fixed
service, the mobile service (Nos. 5499 and 5.500) and the
radionavigation service (No. 5.501);

d\) that Resolution 733 of WRC-2000 invited the ITU-R to conduct
studies, as a matter of urgency, on the sharing constraints indicated in
Nos. 5.502 and 5.503, with a view to review the constraints in No.
5.502;

e\) that No. 5.502 was modified to allow GSO fixed-satellite service
systems to operate earth station antennas with no limit on the antenna
in the band 13.75 - 14.0 GHz subject only to a power flux density limit
at 36m above sea level at the baseline (low water mark as defined in UN
Convention on Law of the Sea 1982) of -114.7 dBW/m2/10MHz for 0.1 % of

another Administration;

g\) that there may be several mitigation techniques available to the GSO
fixed-satellite service earth stations referred to in *considering f)*,
including natural and man-made site shielding, minimum elevation angle,
etc, that will offer significant signal discrimination,

*resolves*

1.  that administrations use the methodology in Annex 1 to calculate the
    power flux density level at 36m above sea level at the baseline (low
    water mark as defined in UN Convention on Law of the Sea 1982) or at
    3 m above ground level at the border of another administration from
    a GSO FSS earth station operating in the 13.75-14 GHz band

*invites ITU-R*

to study, as a matter of urgency, additional technical and procedural
measures (e.g., natural and man-made site shielding) which GSO
fixed-satellite service earth stations operating in the frequency band
13.75 - 14.0 GHz, should take to ensure the power flux density limit in
considering d) is met.

### ANNEX 1 {#annex-1 .unnumbered}

Method for calculating the power flux-density at Radiolocation stations
located at the baseline[^2] or at the border of an Administration
produced by GSO FSS Earth stations in the 13.75-14 GHz band

#### 1 General {#general .unnumbered}

1.1 This Annex describes a method of calculating the interference
potential from GSO FSS earth station transmitters to Maritime or
land-based mobile radiolocation receivers.

2.  This method is in two parts:

```{=html}
<!-- -->
```
a)  the calculation of the likely power flux-density produced at any
    point 36m above sea level at the baseline or at any point 3 m above
    ground level at the border of another administration;

b)  The calculation of the likely power flux-density produced at any
    point 36m above sea level at the baseline or at any point 3 m above
    ground level at the border of another administration taking into
    account the site shielding and other mitigation techniques

1.3 The interference potential of a GSO FSS earth station transmitter
must be considered case by case; the power flux-density produced by each
GSO FSS earth station transmitter into a maritime radiolocation receiver
at a point 36m above the baseline or into a land-based mobile
radiolocation receiver at a point 3m above ground level at the border of
another administration shall be less than the interference power
flux-density limit.

1.4 It is emphasized that, should the calculation described in this
Annex indicate that the maximum permissible power flux-density is
exceeded, it does not necessarily preclude the introduction of an FSS
earth station since the calculations are based on specific assumptions
for:

*a)* the nature of the terrain of the interference path;

*b)* the off-beam discrimination on the radiolocation receiving
installations;

*c)* the necessary protection ratios for the radiolocation service;

*d)* the type of maritime radiolocation service that will be deployed in
that area;

*e)* the value of power flux-density to be protected in the
radiolocation service;

*f)* the specific propagation conditions between the GSO FSS earth
station and the radiolocation receiver.

**2 Limit of power flux-density**

### General {#general-1 .unnumbered}

The interference power flux-density from a GSO FSS earth station
transmitter into a radiolocation receiver at 36m above the baseline or
at 3m above ground level at the border of another administration shall
not exceed the following:

*X dBW/m^2^/10MHz for more than Y % of the time* (1)

where:

*X*  the maximum permissible interfering power flux-density (dB(W/m2))
within the 10 MHz bandwidth of the radiolocation receiver;

*Y*  the percentage of time the GSO FSS earth station interfering power
flux-density, X, would be seen by the radiolocation receiver;

**2.2 Single entry Power Flux Density Level**

2.2.1 The single entry power flux density level to protect for the
Radiolocation receiver is based on an I/N requirement of --6dB which
corresponds to an interference level of --133 dBW in a bandwidth of 10
MHz at the receive output flange of a radiolocation antenna.

2.2.2 A signal from a GSO FSS earth station should be considered only if
its necessary bandwidth overlaps the 13.75-14 GHz band.

3.  The pfd level at the radiolocation antenna which would correspond to
    the --133 dBW /10MHz to the receiver can be derived as follows:

> Since the gain of the radiolocation toward the horizon is 26 dBi, its
> effective aperture calculated from equation (4) is:

A~e~ dBm^2^ = 26 dBi + (--44.3 dBm^2^) = --18.3 dBm^2^. (2)

> Thus, at the point in its scan where the radiolocation antenna is
> pointed at the FSS ES, the received interfering signal power at the
> output of the antenna is:

If I = -133 dBW/10MHz

I = pfd + Ae = --133 dBW/10MHz - (--18.3 dBm^2^)

pfd = --114.7 dBW/m^2^/10MHz. (3)

A pfd of --114.7 dBW/ m^2^/10MHz at the face of the antenna would just
meet the --6 dB I/N threshold whenever the radiolocation antenna is
pointed directly at the FSS ES.

**2.3 Probability of Interference**

1.  The probability that the radiolocation receiver would receive
    interference from a GSO FSS earth station would depend upon the
    radiolocation antenna beamwidth and the rotation/scan angle, and the
    variation of the propagation loss as a function of time.

2.  The duty factor of an individual FSS earth station should also be
    taken into account in the calculation of the percentage of time that
    the power flux-density is received at the radiolocation receiver.

3.  The combined probability of interference into the main beam of the
    radiolocation antenna and the interference path propagation loss
    should be equivalent to 0.1 % of the time.

**2.4 Radiolocation Antenna Pattern**

1.  The azimuthal angular discrimination of the radiolocation antenna is
    shown in Figure 1 and the parameters for the radiolocation antenna
    are given in Table 1.

**Figure 1. Radar Antenna Gain Pattern as a Function of Azimuth Off-Axis
Angle**

    antenna gain in the direction of the horizon would be approximately
    26 dBi.

# 3 Power flux-density produced by a GSO FSS Earth station (*Fp*) {#power-flux-density-produced-by-a-gso-fss-earth-station-fp .unnumbered}

The power flux-density *Fp* (dB(W/m2-10MHz)) produced at any point on
the baseline or the border where a radiolocation station could be
located is determined from the following formula:

*Fp* *P~i~* + G-- *A* 44.3 (4)

where:

*P~i~*  the input power (dBW/10MHz) into the FSS earth station antenna;

G: the gain (dBi) of the GSO FSS earth station in the direction of the
radiolocation station, taking into account the elevation and azimuth
angle discrimination;

*A*  the total path loss (dB).

## Evaluation of path loss *A* for a GSO FSS earth station at a distance greater than 100 km from baseline or the border of another administration

For path lengths greater than 100 km, *A* is given by:

> *A* path loss to be calculated by relevant ITU-R Recommendations (Rec
> ITU-R P.452-10 and Rec. ITU-R P.526)[^3] (5)

## 3.2 Evaluation of path loss *A* for a GSO FSS earth station at a distance equal to or less than 100 km from the baseline or the border of another administration {#evaluation-of-path-loss-a-for-a-gso-fss-earth-station-at-a-distance-equal-to-or-less-than-100-km-from-the-baseline-or-the-border-of-another-administration .unnumbered}

For path lengths equal to or less than 100 km, *A* is calculated using
equations (6) and the value obtained is substituted in formula (4) to
calculate the power flux-density produced at the point concerned on the
edge of the service area:

> *A* path loss to be calculated by relevant ITU-R Recommendations (Rec
> ITU-R P.452-10 and Rec. ITU-R P.526)^3^ (6)

## 3.3 Calculation of the percentage of time factors due to the rotation of the radar and the duty factor of the GSO FSS earth station {#calculation-of-the-percentage-of-time-factors-due-to-the-rotation-of-the-radar-and-the-duty-factor-of-the-gso-fss-earth-station .unnumbered}

Although the power flux-density level calculated in the above sections
corresponds to the level that would be received by the radiolocation
receiver at all times when the GSO FSS earth station is transmitting,
this level corresponds to an I/N of -6 dB only when the interference is
received by the radiolocation system with its antenna directed at the
FSS earth station. Therefore, for times when the azimuth mainbeam of the
radiolocation antenna is not directed toward the GSO FSS earth station,
the interference received will result in an I/N that is less than -6 dB
and the radar will be sufficiently protected. This important factor
needs to be included in the determination of the percentage of time that
a power flux-density level may be exceeded. In order to determine the
percentage of time that the radiolocation receiver would experience an
I/N of -6 dB, the rotation of the radar needs to be taken into account.
As an example, consider the antenna shown in Section 2.4. This antenna
has an azimuth 3 dB beamwidth of 4.4 (2.2 on each side of the mainbeam).
If we assume that this antenna rotates 360 in azimuth, the percentage of
time the power flux-density level calculated above will result in an I/N
of -6 dB is 1.22%. For the rest of the time, the I/N resulting from this
power flux-density level will be less than -6 dB. This calculation
overestimates the percentage of time that the radar will be affected
because the power flux-density at 2.2 off the mainbeam is already 3 dB
below the maximum antenna gain.

Additionally, in determining the percentage of time the calculated power
flux-density level will be received, the duty factor of the individual
GSO FSS earth station needs to be taken into account. Following on the
above example, if the duty factor for the GSO FSS earth station is 10%,
the resultant percentage of time that the power flux-density level will
be received is 1.22% x 10%, or 0.12%.

## 3.4 Distance beyond which the method need not be applied {#distance-beyond-which-the-method-need-not-be-applied .unnumbered}

The method need not be applied when the distance between the GSO FSS
earth station and the baseline or the border of another administration
is greater than:

*a)* 100 km in the case of all overland paths; *or*

*b)* 125 km in the case of all oversea or mixed paths[^4].

**4 Site Shielding and Other Mitigation Techniques**

In the case that the calculation of the power flux-density level and
percentage of time in Section 3 results in a level that exceeds the
interference threshold for the radiolocation system, other mitigation
techniques, such as site shielding, may be used at the GSO FSS earth
station in order to reduce the power flux-density to a level that meets
the threshold. Further study is necessary to determine the additional
signal discrimination from both natural and man-made site shielding.

**Reason:**

This resolution is necessary to define a calculation methodology to be
used by Administrations when FSS earth stations are deployed in the
frequency band 13.75 - 14.0 GHz.

**MOD 5.502** In the band [13.75 - 13.875]{.underline}~~-14 GHz~~, an
earth station in the fixed-satellite service shall have a minimum
antenna diameter of 4.5 m and the e.i.r.p. of any emission should be at
least 68 dBW and should not exceed 85 dBW. [In the band 13.875 - 14 GHz,
an earth station of a non-geostationary fixed-satellite service network
shall have a minimum antenna diameter of 4.5 m.]{.underline} In addition
the e.i.r.p., averaged over one second, radiated by a station in the
radiolocation or radionavigation services [in the band 13.75 - 14
GHz]{.underline} shall not exceed 59 dBW. The protection of assignments
to receiving space stations in the fixed-satellite service operating
with earth stations that, individually, have an e.i.r.p. of less than 68
dBW shall not impose constraints on the operation of the radiolocation
and radionavigation stations operating in accordance with the Radio
Regulations. No. 5.43A does not apply. ~~See Resolution 733
(WRC‑2000).~~ 

**Reason:** This modification will result in the same level of
protection for the radiolocation systems in 125 MHz of the spectrum as
they receive today. It will also result in the same level of protection
for the SRS systems. This allows for the operation of FSS earth
terminals smaller than 4.5 meters in a portion of the band.

**IV. Informal Working Group 6: Public Protection and Other Issues**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/128(22.07.02)

**Agenda Item 1.3**: to consider identification of globally/regionally
harmonized bands, to the extent practicable, for the implementation of
future advanced solutions to meet the needs of public protection
agencies, including those dealing with emergency situations and disaster
relief, and to make regulatory provisions, as necessary, taking into
account Resolution 645 (WRC-2000);

**Background** -- WRC-2000 considered the growing telecommunications
needs of public protection and disaster relief agencies for future
advanced solutions employing high data rates, video and multimedia
technologies, and the need for interoperability among service providers
dealing with emergency situations and disaster relief in developing
Resolution 645.[^5] In recognition of the importance of such growing
national needs to the maintenance of law and order and the protection of
life and property, WRC-2000 resolved to consider the identification of
globally/regionally harmonized bands for advanced solutions for Public
Protection and Disaster Relief (PPDR) at WRC-2003 (WRC-03) and to make
regulatory provisions, as necessary.

ITU-R Working Party 8A (WP-8A) was designated as having responsibility
to undertake appropriate studies related to public protection and
disaster relief and report the results of these studies to WRC-03. A
questionnaire was developed and addressed to Members and Sector Members
of ITU-R (Circular Letter 8/LCCE/83 dated Nov. 20, 2000) in order to
assess the current activities, future plans and intentions with regard
to public protection and disaster relief communications. A Work Plan for
studies on public protection and disaster relief was also approved (Doc.
8A/TEMP/012 Rev 1). The questionnaire viewed the development of public
protection and disaster relief communications in the context of
narrowband, wideband and broadband technologies (PPDR)**.** At an
interim meeting of WP-8A Working Group 3 (WP-8A3), held from April 2-6,
2001 in Goa, India, the responses to the questionnaire from 37
Administrations, four Sector Members and two international groups were
analyzed indicating that most national PPDR communications at present
are dependent upon the use of narrowband analog technologies with a
trend toward the introduction of narrowband digital technologies. The
individual responses of Administrations were focused almost exclusively
on assessment of national PPDR requirements and identified existing
domestic allocations for PPDR uses, noting that a degree of regional
harmonization already exists for narrowband PPDR.

At the October 2001 WP-8A meeting, a number of Working Documents were
prepared for consideration at the February 2002 interim meeting of
WP-8A3. They included a Working Document on user requirements and
applications for PPDR communications (Doc.8A/TEMP/64), while another was
a working document towards a PDNR titled "Global Cross-Border
Circulation of Radiocommunication Equipment" (Doc.8A/TEMP/51). The
methodology for calculating spectrum requirements for PPDR was further
analyzed. As a result, a third working document (Doc.8A/TEMP/50) was
created which describes the methodology and identifies the steps
required in order to complete the studies related to the calculation of
PPDR spectrum requirements. A fourth working document was prepared that
lists potential PPDR candidate bands for consideration by WRC-03,
including initial summaries of the particular advantages and
disadvantages of each band (Doc. 8A/TEMP/62). Finally, a working
document was prepared proposing CPM text for Chapter 2 of the draft CPM
Report (Doc.8A/TEMP/33). The deadline for completion of the Draft CPM
Report was May 31, 2002.

Despite these various working documents, the underlying requirement for
global or regional PPDR spectrum harmonization has not yet been
adequately addressed within WP 8A. [These studies do not address the
issue of domestic requirements for additional spectrum for public
protection or disaster relief]{.underline}. In fact, there has been
little support from internationally oriented public safety or disaster
relief organizations for such [regional or global]{.underline}
harmonized spectrum, and there has been significant questioning of the
need for, and concerns raised regarding possible regulatory restrictions
that may result from, designation of spectrum for PPDR. These concerns,
raised by the United Nations and the International Red Cross, are being
addressed in WP-8A. Concerns raised by the US Federal Emergency
Management Agency (FEMA) and the U.S. Department of Justice are also
still being addressed.

If, however, after thorough examination, it is found that globally or
regionally harmonized spectrum is desirable, identification of this
spectrum should be in the form of either a WRC-03 Resolution or
Recommendation, rather than in the Radio Regulations. As a result, the
United States proposes the following:

## USA/1.3/1 {#usa1.31 .unnumbered}

## [NOC]{.underline} {#noc .unnumbered}

ARTICLE 5

Frequency allocations

**Reasons:** At this point in time, there has been little support from
internationally oriented public safety or disaster relief organizations
for regional or global harmonized spectrum. Moreover, there has been
significant questioning of the need for, and concerns raised regarding
possible regulatory restrictions that may result from, international
designation of spectrum for Public Protection or Disaster Relief in the
Radio Regulations. Therefore, in order to avoid any potential
constraints on the ability of individual administrations to use spectrum
in which they currently operate, it is appropriate not to make changes
to Article 5 of the Radio Regulations.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/129(22.07.02)

**WRC-03 Agenda Item 1.36**: to examine the adequacy of the frequency
allocations for HF broadcasting from about 4 MHz to 10 MHz, taking into
account the seasonal planning procedures adopted by WRC-97;

**BACKGROUND.** Since prior to HFBC WARC-84 it was recognized that there
was inadequate spectrum worldwide for the Broadcasting Service, and
especially in the band 4-10 MHz. Broadcasting Service proposals
submitted to WARC-92 identified the need for 700 kHz of additional
spectrum below 10 MHz. However, WARC-92 only allocated 200 kHz,
specifically,

5900-5950 kHz = 50 kHz

7300-7350 kHz = 50 kHz

[9400-9500 kHz = 100 kHz]{.underline}

Total = 200 kHz

In addition, RR 5.134 limits these frequencies to single sideband (SSB)
emissions or any other spectrum efficient methods recommended by ITU-R.
RR 5.136 allocates these bands to other services until 1 April 2007.
Resolution 537(**WRC-97**) called for a survey of HF broadcasting
transmitters and receivers with emphasis on the worldwide distribution
of SSB transmitters and receivers. ITU-R completed this survey in 1999
and submitted its report at WRC-2000, concluding that the limited
availability of SSB transmitters and receivers did not justify the
[mandated]{.underline} conversion from DSB to SSB.

ITU-R Working Party 6E, in drafting the CPM text for Agenda Item 1.36,
provided further evidence that there is a serious shortage of spectrum
available to the HF Broadcasters. The CPM text shows the need for some
800 kHz of additional spectrum to eliminate the current situation of
co-channel and adjacent channel collisions now taking place worldwide in
the 6, 7, and 9 MHz broadcasting bands. This is based on actual data for
the year 2000, collected at the regional high frequency coordinating
conferences (introduced by WRC-97 as part of Article S12).

Additionally, there is the data from the FCC-licensed broadcasters.
These HF Broadcasters are currently using, on a non-interference basis,
some 80 frequency hours in the WARC-92 bands and another 350-plus hours
of "Out of Band" use elsewhere in the spectrum not allocated to the
broadcasting service. Figures on a worldwide basis may be deduced from
the seasonal schedules required by Article S12, and administered by the
High Frequency Coordinating Conference (HFCC).

The results of the previously referred to studies on HF Broadcasting
spectrum requirements confirm that the following proposed additional
spectrum below 10 MHz would reduce considerably the present spectrum
deficiencies for this service:

4500-4650 kHz = 150 kHz

5060-5250 kHz = 90 kHz

5840-5900 kHz = 60 kHz (\*)

7350-7650 kHz = 300 kHz (\*)(\*\*)

9290-9400 kHz = 110 kHz (\*)

9900-9940 kHz [= 40 kHz]{.underline} (\*)

850 kHz

\* Band adjacent to the HF broadcasting bands governed by Article S12

\*\* Band location may need to be revised in light of actions decided
with respect to WRC-03 agenda item 1.23

RESOLUTION XXX

**Implementation of changes in frequency allocations**

**between 4 500 kHz and 9 940 kHz**

The World Radiocommunication Conference (Geneva, 2003),

*considering*

*a)* that parts of the frequency bands between 4 500 kHz and 9 940 kHz
which were previously allocated on an exclusive or shared basis to the
fixed and mobile services have been reallocated to the broadcasting
service;

*b)* that some existing fixed and mobile assignments may need to be
removed progressively from those reallocated bands to make way for the
broadcasting service;

*c)* that the assignments to be removed, termed "displaced assignments",
must be

reaccommodated in other appropriate frequency bands;

*d)* that developing countries may require special assistance from the
Radio-communication Bureau, in replacing their displaced assignments
with appropriate protection;

*e)* that procedures already exist in Article 11 that may be used to
this effect,

*recognizing*

the difficulties that administrations and the Bureau might encounter
during the period of

transition from the previous allocations to those made by WRC 2003,

*resolves*

1 that the duration of the transition period shall be from x July 2003
to 1 April 2007;

2 that administrations should no longer notify any frequency assignments
to stations of the fixed and mobile services in the reallocated bands.
Assignments notified in these bands after x July 2003 shall bear a
symbol to indicate that the finding will be examined by the Bureau as of
1 April 2007 in accordance with the provisions of No. 11.31;

3 that the Bureau shall undertake a continuing action to review the
Master International Frequency Register with the help of
administrations. In this respect, the Bureau shall periodically consult
the administrations concerning the frequency assignments to links for
which another satisfactory means of telecommunication exists, with a
view to either downgrading assignments of class of operation A or
deleting such assignments;

4 that administrations shall, for assignments of class of operation A in
the reallocated bands, either notify the replacement frequencies to the
Bureau or request the Bureau's assistance in selecting the replacement
frequencies in application of Articles 7 and 13;

5 that the Bureau shall develop in due time a draft procedure to be used
for the

replacement of remaining frequency assignments and shall consult
administrations in accordance with Article 14;

6 that the Bureau should modify the draft procedures taking into
account, to the extent practicable, comments received from
administrations, and propose replacement assignments at the latest three
years before 1 April 2007. In so doing, the Bureau shall request
administrations to take appropriate action to bring their assignments in
conformity with the Table of Frequency Allocations by the due date;

7 that a replacement frequency assignment whose basic characteristics,
with the

exception of the assigned frequency, have not been modified in the above
process, shall keep its original date. However, if these basic
characteristics of a replacement frequency assignment are different from
those of the displaced assignment, the replacement assignment shall be
treated in accordance with the relevant provisions of Section II of
Article 11,

*invites administrations*

when seeking reaccommodation of the displaced assignments for their
fixed and mobile services in the bands between 4 500 kHz and 9 940 kHz
which have been reallocated to the broadcasting service, to make every
effort to find replacement assignments in the bands allocated to the
fixed and mobile services concerned.

**REASON**

To facilitate an orderly transition from fixed and mobile allocations to
a broadcasting allocation.

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

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/130(22.07.02)

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

**Modification to Appendix 7 clarify that the procedure is applicable to
case where the two services are allocated on an equal basis including
secondary services.**

**BACKGROUND:** Resolution **86** (Minneapolis, 1998) resolves to
request WRC-2000 and subsequent WRCs to continually review and update
the advance publication, coordination and notification procedures,
including the associated technical characteristics, and the related
Appendices of the Radio Regulations, so as to ensure that they reflect
the latest technologies, as well as to achieve additional simplification
and cost savings for the Radiocommunication Bureau and administrations.

**A modification is needed in Article 9 and Appendix 7 to reflect the
intent of the Appendix 7 procedure to apply to any case where the space
service earth station operates co-frequency with another service where
the allocation status is equal for the two services. See Table 10 in
Appendix 7.**

MOD

**9.17A** *m)* for any specific earth station in respect of other earth
stations, [or typical mobile earth stations in respect of specific earth
stations,]{.underline} operating in the opposite direction of
transmission, in frequency bands allocated with equal rights to space
radiocommunication services in both directions of transmission and where
the coordination area of the earth station includes the territory of
another country or the earth station is located within the coordination
area of another earth station, with the exception of the coordination
under No. **9.19**;

Reason: To include the coordination mechanism to allow coordination
between typical mobile earth stations in respect of specific earth
stations.

### Methods for the determination of the coordination area around an earth station in frequency bands between 100 MHz and 105 GHz {#methods-for-the-determination-of-the-coordination-area-around-an-earth-station-in-frequency-bands-between-100-mhz-and-105-ghz .unnumbered}

### MOD {#mod-2 .unnumbered}

### 1.4.4 Earth stations operating in bidirectionally allocated frequency bands {#earth-stations-operating-in-bidirectionally-allocated-frequency-bands .unnumbered}

For earth stations operating in some frequency bands there may be
~~co-primary~~ allocations to space services operating [with equal
rights]{.underline} in both the Earth-to-space and space-to-Earth
directions. In this case, where two earth stations are operating in
opposite directions of transmission it is only necessary to establish
the coordination area for the transmitting earth station, as receiving
earth stations will automatically be taken into consideration. Hence, a
receiving earth station operating in a bidirectionally allocated
frequency band will only be involved in coordination with a transmitting
earth station if it is located within the transmitting earth station's
coordination area.

For a transmitting earth station operating with either geostationary or
non-geostationary satellites in a bidirectionally allocated frequency
band, the coordination area is determined using the procedures described
in § 3.

Reason: Brings the text in line with existing No. 9.17A and Appendix 5
provisions.

Information Administration (NTIA)**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Doc. WAC/123(22.07.02)**

**WRC-03 Agenda Item 1.3:** to consider identification of
globally/regionally harmonized bands, to the extent practicable, for the
implementation of future advanced solutions to meet the needs of public
protection agencies, including those dealing with emergency situations
and disaster relief, and to make regulatory provisions, as necessary,
taking into account Resolution **645 (WRC 2000)**;

**Background Information**: WRC**‑**2000 considered the benefits of
globally/regionally harmonized frequency bands for future advanced
solutions for public protection and disaster relief and an increasing
need for interoperability and inter-working between security and
emergency networks, both nationally and for cross-border operations, in
emergency situations and disaster relief. The guidance regarding ITU-R
studies under agenda item 1.3 is provided in Resolution **645
(WRC‑2000)**. This resolution includes the study of possible spectrum
for future advanced solutions for public protection and disaster relief.
It also includes the possible development of a resolution identifying
the technical and operational basis for global cross-border circulation
of radiocommunication equipment in emergency and disaster relief
situations.

Based on the studies conducted by the ITU-R, the United States believes
that any spectrum recognized for future advanced solutions for public
protection and disaster relief should be developed in an ITU-R
Recommendation and linked to the Radio Regulations through a WRC
Recommendation. This approach provides recognition of spectrum used for
public protection and disaster relief, acknowledges the need for
national prerogatives, and allows flexible updates without maintaining a
WRC agenda item specifically for this issue. The United States believes
it is important to preserve the prerogatives of Administrations to
implement spectrum for future advance solutions for public protection
and disaster relief applications. The attached proposed WRC
Recommendation allows for recognition of spectrum for future advanced
solutions for public protection and disaster relief without conveying
any status or priority under the radio regulations, as well as, provides
uniform guidance to Administrations, users and manufacturers. This
recognition has several advantages such as facilitating economies of
scale in the production of radiocommunication equipment for public
protection and disaster relief, consolidation of duplicated
infrastructure, improved spectrum efficiency, potential for
interoperability nationally, regionally as well as internationally, and
improved operational effectiveness. A WRC Recommendation would help to
facilitate cross-border public protection operations and effective
international response to emergency and disaster relief situations when
required and would provide the potential for relief organizations around
the world to communicate and interact more quickly and efficiently,
thereby speeding disaster relief efforts without constraining their
ability to use spectrum in which they currently operate. At the same
time, recognition of spectrum for future advanced solutions should not
preclude the use of any spectrum in bringing disaster relief.

**Proposal**:

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

Article 5

**Frequency Allocations**

**Reasons**: The United States does not support identification of
spectrum for public protection and disaster relief in the Table of
Frequency Allocations (Article 5 of the Radio Regulations).

RECOMMENDATION PUBLIC PROTECTION AND DISASTER RELIEF (PPDR) (WRC-03)

Public protection and disaster relief

The World Radiocommunication Conference (Geneva, 2003),

*considering*

a\) the growing telecommunication needs of public agencies and
organizations dealing with law and order, disaster relief, emergency
response and including the protection of life and property;

b\) that future advanced solutions used by such public protection and
disaster relief agencies and organizations will require high data rates;

c\) that current public protection and disaster relief applications are
mostly narrow-band, including voice and low data‑rate applications,
typically in channel bandwidths of 25 kHz or less; that in even in times
of disasters, when most terrestrial-based networks are destroyed,
amateurs,

d\) that in even in times of disasters, when most terrestrial-based
networks are destroyed, amateurs, satellite and other non-terrestrial
networks can still provide communications services to assist in public
protection and disaster relief efforts;

e\) that although there will continue to be narrow‑band requirements,
many future applications will be wideband (indicative data rates in
range of 384-500 kb/s) and broadband (indicative data rates in range of
1-100 Mbit/s) with channel bandwidths dependant on use of spectrally
efficient technologies;

f\) that technology exists today to enable dissimilar radios to be
interoperable across different spectrum with different waveforms;

g\) that commercial systems can serve as a complement to dedicated
systems in support of public protection and disaster relief applications
and that such complementary use would be in response to market demands;

h\) that there is potential for new technologies such as IMT-2000 and
systems beyond and Intelligent Transportation Systems (ITS) that will
support or supplement advanced public protection and disaster relief
applications;

i\) that Resolution **98 (PP-98)** urges Member States to facilitate use
of telecommunications for the safety and security of humanitarian
personnel,

*recognizing*

a\) the importance of interoperability in the provision of
administrations recognizing and making available spectrum for public
protection and disaster relief with the benefits of:

i\) increased potential for interoperability;

ii\) a broader manufacturing base and increased volume of equipment
resulting in economies of scale and expanded availability of equipment;

iii\) improved spectrum management and planning;

iv\) enhanced cross‑border and international coordination;

v\) improved cross-border circulation of equipment;

vi\) efficient use of radio frequency spectrum

b\) that spectrum planning for public protection and disaster relief is
done at the national level, should taken into account the need for
interoperability and recognized spectrum of neighboring administrations;

c\) the benefits of cooperation between countries for the provision of
effective humanitarian assistance during disasters;

d\) the needs of countries, particularly for developing countries, for
low‑cost communication equipment for public protection and disaster
relief agencies and organizations;

e\) that the trend is to increase the use of Internet Protocol (IP)
based technologies;

f\) that advanced technologies such as software defined radios, cross
banding, advanced compression waveforms and networking may help lessen
the need for harmonizing spectrum to satisfy public protection and
disaster relief requirements

noting

a\) applications requiring large coverage areas and providing good
signal availability would generally be accommodated in lower spectrum;

b\) that many administrations use spectrum below 1 GHz primarily for
narrow-band public protection and disaster relief applications;

c\) applications requiring wider bandwidths would generally be
accommodated in progressively higher spectrum;

d\) that in most administrations, public protection and disaster relief
applications are provided at multiple administrative levels, starting
with national down to local levels, and cooperation between the levels
is a national matter to which recognized spectrum and interoperable
operations could assist;

e\) the existing investment in systems supporting public protection and
disaster relief that many administrations have made;

f\) that flexibility must be afforded to disaster relief agencies and
organizations to use current and future radiocommunication in an
independent manner, so as to facilitate their humanitarian operations.

*recommends*

1\. that administrations encourage public protection and disaster relief
agencies and organizations to utilize both existing and new technologies
and solutions, to the extent practicable, to satisfy their national
public protection and disaster interoperability requirements and to
further the national goals of public protection and disaster relief
agencies and organizations;

2 that administrations encourage agencies and organizations to use
advanced wireless solutions,

such as IMT-2000 and ITS, for providing complementary support for the
communication needs of public protection and disaster relief agencies
and organizations,

further recommends

1\. that administrations continue to use spectrum below 1 GHz for
narrow-band PPDR applications;

2\. that administrations encourage public protection and disaster relief
agencies and organizations to utilize relevant ITU-R Recommendations in
planning spectrum use and implementing technology and systems supporting
public protection and disaster relief;

3\. that recognition of spectrum for public protection and disaster
relief should not preclude the use of any other spectrum to bring aid in
times of disaster and humanitarian assistance.

**Reasons**: A WRC Recommendation, without any specific identification
in Article **5** of the Radio Regulations avoids misinterpretation of
the regulatory status of systems supporting public protection and
disaster relief applications and disassociates any additional
recognition of spectrum for public protection and disaster relief from
the Table of Frequency Allocations. Different Regional proposals
intended to cover spectrum options can be noted in the text of the
Recommendation.

## USA/ /3 SUP {#usa-3-sup .unnumbered}

RESOLUTION 645 (WRC-2000)

**Reasons**: It is possible to conclude this agenda item at WRC‑03 on
the basis that the necessary regulatory requirements have been met.
Resolution **645 (WRC‑2000)** should be suppressed.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

Doc. WAC/124(22.07.02)

## WRC-03 Agenda Item 1.12a: to consider allocations and regulatory issues related to the space science services in accordance with Resolution 723 (Rev. WRC-2000); {#wrc-03-agenda-item-1.12a-to-consider-allocations-and-regulatory-issues-related-to-the-space-science-services-in-accordance-with-resolution-723-rev.-wrc-2000 .unnumbered}

Background Information: ITU-R Recommendation SA.363-5 recommends that
frequencies below 1 GHz are technically suitable for telecommand of
satellites in the space science services operating below an altitude of
2000 km. A deficiency in telecommand (uplink) frequency allocations has
been previously identified, compared to the available telemetry
(downlink) allocations in the 100 MHz to 1 GHz range. The deficiency was
first noted in Resolution 712 (WARC-92), repeated in Resolution 712
(Rev. WRC-95), and again in Resolution 723 (WRC-97).

This item was originally placed on the WRC-97 agenda. WRC-97 determined
that insufficient study had been completed to take action on this agenda
item.

Since WRC-2000, additional studies have been undertaken in the ITU-R.
The study results show that show that separation distances for
aeronautical mobile stations must be over 400 km and for MSS
approximately 100 km. These required coordination distances make use of
RR 9.17/17a and Appendix 7 impractical and will result in large
geographical regions where existing Aeronautical Mobile, MS, FS, and MSS
services are unusable.

**Reasons: ITU-R studies have shown that sharing between telecommand and
existing services in the 225 -- 400 MHz band results in impractical
coordination requirements with existing services.**

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Doc. WAC/122(22.07.02)**

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

**Modification to Appendix 7 clarify that the procedure is applicable to
case where the two services are allocated on an equal basis including
secondary services.**

**BACKGROUND:** Resolution **86** (Minneapolis, 1998) resolves to
request WRC-2000 and subsequent WRCs to continually review and update
the advance publication, coordination and notification procedures,
including the associated technical characteristics, and the related
Appendices of the Radio Regulations, so as to ensure that they reflect
the latest technologies, as well as to achieve additional simplification
and cost savings for the Radiocommunication Bureau and administrations.

**A modification is needed in Article 9 and Appendix 7 to reflect the
intent of the Appendix 7 procedure to apply to any case where the space
service earth station operates co-frequency with another service where
the allocation status is equal for the two services. See Table 10 in
Appendix 7. This clarification relates to the situation that will exist
when allocation change being made under Agenda Item 1.11 becomes
effective.**

MOD

**9.17A** *m)* for any specific earth station [or typical mobile earth
station]{.underline}, in respect of other earth stations operating in
the opposite direction of transmission, in frequency bands allocated
with equal rights to space radiocommunication services in both
directions of transmission and where the coordination area of the earth
station includes the territory of another country or the earth station
is located within the coordination area of another earth station, with
the exception of the coordination under No. **9.19**;

### Methods for the determination of the coordination area around an earth station in frequency bands between 100 MHz and 105 GHz {#methods-for-the-determination-of-the-coordination-area-around-an-earth-station-in-frequency-bands-between-100-mhz-and-105-ghz-1 .unnumbered}

### MOD {#mod-3 .unnumbered}

### 1.4.4 Earth stations operating in bidirectionally allocated frequency bands {#earth-stations-operating-in-bidirectionally-allocated-frequency-bands-1 .unnumbered}

For earth stations operating in some frequency bands there may be co-
[equal]{.underline} ~~primary~~ allocations to space services operating
in both the Earth-to-space and space-to-Earth directions. In this case,
where two earth stations are operating in opposite directions of
transmission it is only necessary to establish the coordination area for
the transmitting earth station, as receiving earth stations will
automatically be taken into consideration. Hence, a receiving earth
station operating in a bidirectionally allocated frequency band will
only be involved in coordination with a transmitting earth station if it
is located within the transmitting earth station's coordination area.

For a transmitting earth station operating with either geostationary or
non-geostationary satellites in a bidirectionally allocated frequency
band, the coordination area is determined using the procedures described
in § 3.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Doc. WAC/125(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);

**Background Information**: The Table of Frequency Allocations currently
extends to 275 GHz. Footnote **5.565,** which was extensively modified
by WRC-2000 to accommodate science requirements, 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
> for the following spectral line measurements for passive services:
>
> \- 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;
>
> \- Earth exploration-satellite service (passive) and space research
> service (passive): 275-277 GHz, 294-306 GHz, 316-334 GHz, 342-349 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.
>
> Future research in this largely unexplored spectral region may yield
> additional spectral lines and continuum bands of interest to the
> passive services. Administrations are urged to take all practicable
> steps to protect these passive services from harmful interference
> until the date when the allocation Table is established in the
> above-mentioned frequency band.

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.

**Reasons**: To review the issues related to the current and future use
of this portion of the frequency spectrum.

**USA/ / 3 ADD**

**2.3.1** to review studies and consider allocations in the frequency
bands between 275 GHz and 1 000 GHz to the passive science services,
taking account of the needs of other services such as the amateur
service;

**Reasons**: Passive science sensors and radio astronomy are already
utilizing frequency bands in the 275 - 1000 GHz region and many more
systems are planned for these bands. In the past, the amateur service
has often proven to be compatible with these services.

**USA/ / 4 ADD**

**2.3.2** to review studies with a view to identifying future
requirements for applications in the frequency bands above 1 000 GHz;

**Reasons**: Both active and passive services have demonstrated
operations above 1000 GHz, and even above the 3 000 GHz limit contained
in **1.5** of the Radio Regulations. The proposed change to the ITU
Convention (Marrakech, 2002) also necessitates a review of studies
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.
