**Agenda item 1.4**

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

**Background Information**

Resolution 228 (WRC-03) calls for studies on frequency-related matters
for the "future development of IMT-2000" (now referred to as "IMT-2000")
and "systems beyond IMT-2000" (now named "IMT-Advanced") as defined by
ITU-R. Resolves 2 under Resolution 228 (WRC-03) invites the ITU-R to
report, in time for WRC-07, on the results of studies on the spectrum
requirements and potential frequency ranges suitable for IMT-2000 and
IMT-Advanced, taking into account:

-   the evolving user needs, including the growth in demand for IMT-2000
    services;

-   the evolution of IMT-2000 and pre-IMT-2000 systems through advances
    in technology;

-   the bands currently identified for IMT-2000;

-   the time-frame in which spectrum would be needed;

-   the period for migration from existing to future systems;

-   the extensive use of frequencies below those identified for IMT-2000
    in RR No. 5.317A.

WARC-92 identified the bands 1 885-2 025 MHz / 2 110-2 200 MHz and
WRC-2000 identified the bands 806-960 MHz (ITU-R Region 1: 862-960 MHz)
/ 1 710-1 885 MHz / 2 500-2 690 MHz for use on a worldwide basis by
administrations wishing to implement IMT-2000 systems. Resolutions 212
(WARC 92), 223 (WRC-2000) and 224 (WRC-2000) invite administrations to
make available the necessary portion of these identified bands for
IMT-2000 development, while recognizing that administrations have the
flexibility to use the bands for other applications of services to which
the bands are allocated and to implement IMT-2000 in other mobile bands.

As part of the process to identify candidate bands to meet the potential
spectrum requirements for IMT-2000 and IMT-Advanced (collectively
referred to as "IMT"), Resolution 228 calls for technical studies on the
compatibility with existing services in the bands of interest. However,
at this time such studies have not been completed.

The candidate bands for IMT-2000 and IMT-Advanced systems contained in
ITU-R Report M.2079 are between 400 MHz and 5 GHz and in numerical order
are:

-   410-430 MHz

-   450-470 MHz

-   470-960 MHz

-   1 710-2 025 MHz and 2 110-2 200 MHz

-   2 300-2 400 MHz

-   2 500--2 690 MHz

-   2 700-2 900 MHz

-   3 400-4 200 MHz

-   4 400-4 990 MHz

Five of the bands (or portions thereof) identified as candidates,
410-430 MHz, 470-960 MHz, 2 700-2 900 MHz, 3 400-4200 MHz, and 4 400-
4990 MHz, are considered in this proposal.

**[410-430 MHz]{.underline}**

The band 410-430 MHz is used extensively by many administrations for
fixed and mobile communications systems, long-range surveillance
systems, as well as personnel location systems. Ground, shipborne, and
airborne radars, which are used for national security, utilize this
particular frequency band. Parts of the band are also used for extra
vehicular activity (EVA) communications by both the Shuttle and
International Space Station on a primary basis for the space research
service; and for transmitting hydrological and meteorological data.

**[470-960 MHz]{.underline}**

The conversion to digital broadcast television technologies is underway
in many countries around the world. It is expected that within the next
decade most countries will transition to digital broadcasting. The
United States for example, plans to complete the conversion to digital
broadcast television in 2009. As a result of this conversion, additional
spectrum will become available for implementation of advanced wireless
applications (e.g. IMT). In order to maximize the benefit of this newly
available spectrum it is important to establish an international
regulatory framework that would allow adequate time for national
regulators, manufacturers and operators to prepare for the introduction
of the new services. In light of that, the timing of WRC-07 is highly
advantageous, as it provides an opportunity to identify the spectrum in
the broadcasting bands that would facilitate eventual transition from
broadcasting to advanced wireless technologies.

**[2700-2900 MHz]{.underline}**

In all three ITU-R Regions, the 2 700-2 900 MHz band is allocated to
aeronautical radionavigation. The radionavigation service is designated
as a safety service under RR No. 4.10 and harmful interference to it
cannot be accepted. By RR No. 5.423, ground-based meteorological radars
are authorized to operate on an equal primary basis. Previous detailed
analysis and sharing studies undertaken by various ITU administrations
and ongoing within the ITU-R working parties have shown that the
utilization of the 2 700-2 900 MHz band by IMT systems is not feasible.

**[3400-4200 MHz]{.underline}**

The 3 400-3 600 MHz band is allocated to the radiolocation service on a
primary basis in ITU-R Regions 2 and 3. The band 3 400-3 600 MHz is
allocated to the radiolocation service on a secondary basis in ITU-R
Region 1 and the band 3 600-3 700 MHz band is allocated to the
radiolocation service on a secondary basis in ITU-R Regions 2 and 3. In
this frequency range, administrations have developed and deployed a
variety of mobile and transportable high power radar systems that
operate on land, on ships, and on aircraft. The shipborne radars are
principally used in coastal areas, but can also be used during open
ocean transit. The airborne radars are highly mobile and operate in many
areas of the world. A number of ongoing sharing studies submitted to the
ITU-R have indicated that sharing in the 3 400-3 700 MHz band between
the radiolocation service and IMT-Advanced systems operating in the
mobile service is not feasible in the same geographic area due to
significant levels of interference into both the radar systems and
IMT-Advanced devices.

Sharing studies have been conducted within the ITU-R regarding sharing
of IMT-2000 and IMT-Advanced with FSS receive earth stations. To provide
protection to the FSS receive earth stations, some physical separation
to the stations of the mobile terrestrial network is required. The
magnitude of this separation distance depends on the parameters of the
networks and the deployment of the two services, including the elevation
angle of the earth station, the position of the IMT-Advanced terminal
and/or base station relative to the FSS earth station and the amount of
clutter loss. While the studies are still ongoing, the current range of
separation distances associated with a single IMT-Advanced macro base
station is from 36 to 70 km for the non-site specific studies (flat
terrain model) if only long term interference is considered, and from
34-430 km if short term effects are also considered. It should be noted
that the 34 kilometer distance for short-term interference does not
include the effects of ducting. If ducting effects are taken into
account, the separation distance associated with short term interference
ranges from 140 -- 430 km. For site specific studies, where actual
terrain profiles were taken into account, the current range of
separation distances associated with a single IMT-Advanced macro base
station is 1 to 110 km if only long term interference is considered and
270 km to 280 km if short term effects are also considered. It is noted
that the 270 -- 280 km distance corresponds to the results of a single
(and only) site specific sharing study by Working Party 8F that
considered the effects of short-term interference. It should also be
noted that mitigation techniques are also under study that may reduce
the separation distances. The minimum separation distances related to
the IMT-Advanced micro and/or mobile station will generally be smaller
than the ranges listed above.

Although the studies have differences in assumptions and methodologies
and need to be continued to find convergence, they all show that
ubiquitously deployed IMT-Advanced systems can not share in the same
geographical area with FSS, when the FSS is deployed in a ubiquitous
manner and/or with no individual licensing of earth stations, since no
minimum separation can be guaranteed.

In view of the results of the available sharing studies to date and the
above considerations, the band 3700-4200 MHz should be removed from
consideration as a candidate band for IMT-Advanced systems.

**[4400-4990 MHz]{.underline}**

The 4 400- 4990 MHz band is allocated on a primary basis to the fixed
and mobile (except aeronautical) services. The 4 500-4 800 MHz band is
also allocated on a primary basis to the fixed satellite service,
subject to Appendix 30B. ITU-R Working Party 8B concluded studies under
agenda item 1.5 that show aeronautical telemetry systems for flight test
can share with fixed and mobile systems in this band. Use of this band
includes many datalinks and a number of unmanned air systems networks.
Troposcatter radio terminals are deployed in this band to provide secure
digital long-haul radio trunking. Systems in this band include
deployable communications systems as well as fixed and mobile radio
relay networks.

The 4 400--4990 MHz band is designated by several administrations in
Europe and North America as a harmonised band to be used for defense
communications and thus is critical to these administrations' ability to
fulfill their peacekeeping obligations. The 4940-4990 MHz band is
designated for use in many countries by public protection and disaster
relief (PPDR) applications, particularly for broadband. This usage is
reflected in Resolution 646 (WRC-03), which identifies the 4940-4990 MHz
band for PPDR applications in Regions 2 and 3. The term "public
protection radiocommunication" refers to radiocommunications used by
responsible agencies and organizations dealing with maintenance of law
and order, protection of life and property and emergency situations. The
term "disaster relief radiocommunication" refers to radiocommunications
used by agencies and organizations dealing with a serious disruption of
the functioning of society, posing a significant widespread threat to
human life, health, property or the environment, whether caused by
accident, natural phenomena or human activity, and whether developing
suddenly or as a result of complex, long-term processes. It must be
noted, however, that Resolution 646 also states specifically in
*considering h)*: that continuing development of new technologies such
as IMT‑2000 and systems beyond IMT‑2000 and Intelligent Transportation
Systems (ITS) may be able to support or supplement advanced public
protection and disaster relief applications.

410-460 MHz

**Reasons**: ITU-R studies have not shown compatibility between IMT
systems and the incumbent services in the 410-430 MHz band. Extensive
use of this band for national security and public safety purposes
preclude the use of this band for commercial wireless purposes.

**Reasons**: To establish consistent worldwide primary Mobile allocation
in the band 698‑806 MHz and identify this band for the advanced
communications applications, including IMT. The proposed modifications
would facilitate harmonized development and deployment of advanced
communications applications in frequency bands below 1GHz.

**MOD** USA/ /3

**5.317A**

**5.317A** Administrations wishing to implement International Mobile
Telecommunications (IMT) may use those parts of the band 698-960 MHz
which are allocated to the mobile service on a primary basis and are
used or planned to be used for mobile systems (see Resolution **224
(Rev.** **WRC-07))**. This identification does not preclude the use of
these bands by any application of the services to which they are
allocated and does not establish priority in the Radio Regulations.

**Reasons**: **To identify spectrum for advanced communications
applications including** International Mobile Telecommunications **(IMT)
to facilitate consistent deployment.**

Note: The United States is of the view that it is important for spectrum
identifications for advanced communications applications to be flexible
enough to accommodate new technologies.  In this regard, it is important
to note that the United States continuous to fully supports the ongoing
efforts at the ITU-R to include WiMAX (OFDMA TDD WMAN) in the IMT-2000
family (Recommendation ITU-R M.1457).  The United States is optimistic
that these efforts will be completed prior to WRC-07 and is hopeful that
there will be no need to revisit this proposal in order to ensure that
WiMAX is included in the IMT identifications.

**Reasons**: The United States proposes no change to 3400-3700 MHz and
3700-4200 MHz for the following reasons. ITU-R studies have not shown
compatibility between IMT systems and the radiolocation service in the
3 400-3 700 MHz band. In the United States, the fixed-satellite service
deployments have been halted in order to not constrain terrestrial use
of the band while protection of existing earth stations has been
ensured. The results of the ITU-R sharing studies to date have shown
that sharing of the 3700 -- 4200 MHz frequency band by IMT-Advanced
systems and the fixed satellite system is not feasible within the same
geographic area.

**Reasons**: Studies have not shown the compatibility of IMT with the
radio relay and troposcatter networks operating within the fixed and
mobile services in the 4400-4940 MHz band. Further, the 4940-4990 MHz
band is used for critical public protection and disaster relief
applications. This [NOC]{.underline} proposal applies to Agenda Item 1.4
and the identification of spectrum for IMT. The 4 500-4 940 MHz band is
being considered for aeronautical mobile telemetry for flight test
(air-to-ground) under Agenda Item 1.5.

beyond IMT-2000, otherwise known as IMT-Advanced;

f\) that the technical characteristics of IMT-2000 are specified in
ITU-R and ITU-T Recommendations, including Recommendation ITU-R M.1457,
which contains the detailed specifications of the radio interfaces of
IMT-2000;

g\) that IMT-Advanced is being studied within ITU-R, and the framework
for its development and its overall objectives is contained in
Recommendation ITU-R M.1645;

*h)* that first- and second-generation mobile systems in the three
Regions operate using various frequency arrangements;

*i)* that where cost considerations warrant the installation of fewer
base stations, such as in sparsely populated areas, bands below 1 GHz
are generally suitable for implementing mobile systems including IMT;

*j)* Recommendation ITU-R M.819 which describes the objectives to be met
by IMT‑2000 to meet the needs of developing countries,

recognizing

a\) that the evolution of first- and second-generation cellular-based
mobile systems to IMT‑can be facilitated if they are permitted to use
their current frequency bands;

b\) that the field of mobile wireless telecommunications is experiencing
many rapid improvements in capability, due to technology advances, and
that Administrations should be encouraged to facilitate the deployment
of these rapid improvements;

c\) that the bands below 1 GHz are already heavily used for a wide
variety of terrestrial services, especially in urban areas;

d\) that parts of the band 746-806 MHz and 806-860 MHz are widely used
by some Administrations for point-to-point, point-to-multipoint, trunked
and conventional dispatch systems that include critical applications
such as public protection and disaster relief radiocommunications
(PPDR);

e\) that Resolution 646 (WRC-2003) recommends that administrations use
regionally harmonized frequency bands for PPDR and encourages
Administrations to consider the use of the band 746-806 MHz, among
others, in Region 2, and states that some countries in Region 3 have
identified the 746-806 MHz band for PPDR applications;

emphasizing

*a)* that flexibility must be afforded to administrations:

-- to determine, at a national level, how much spectrum to make
available for IMT from within the identified bands, taking into account
current usages of the spectrum and the need for other applications;

-- to develop their own transition plans, if necessary, tailored to meet
their specific deployment of existing systems;

-- to have the ability for the identified bands to be used by all
services having allocations in those bands;

-- to determine the timing of availability and use of the bands
identified for IMT, in order to meet particular market demand and other
national considerations;

*b)* that the particular needs of developing countries must be met,

resolves

to request administrations which are implementing, or planning to
implement IMT to consider the use of bands below 1 GHz and the
possibility of evolution of first- and second-generation mobile systems
to IMT, in the frequency band identified in No. **5.317A**, based on
market demand and other national considerations;

invites ITU-R

to study compatibility between mobile systems with different technical
characteristics and provide guidance on any impact on spectrum
arrangements.

**Reasons**: To provide guidance to Administrations on considering the
existing uses and other applications that may use the frequency bands
identified for IMT and other broadband wireless access systems below 1
GHz to allow Administrations greater flexibility to select technology
and to also recognize the importance of other applications in the band,
such as Public Protection and Disaster Relief (PPDR).
