[]{#__RefHeading___Toc154581583 .anchor} **Agenda Item 1.4**

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

**Proposal for Agenda item 1.4**

**Background Information**

WARC-92 identified the 1885-2025 MHz and 2110-2200 MHz bands (230
megahertz of spectrum) allocated to the mobile service for possible use
on a worldwide basis by Administrations wishing to implement IMT-2000
systems in footnote 5.388. Additionally, WRC-2000 identified the 806-960
MHz band in footnote **5.317A** and the 1710-1885 MHz and 2500-2690 MHz
bands in footnote **5.384A** for possible IMT-2000 use. Each
Administration would decide which portions of the identified bands to
use for IMT-2000.

In Resolution **228 (WRC-2000)**, WRC-2000 invited the ITU-R to continue
studies on the overall objectives, applications and technical and
operational implementation of IMT systems. At WRC-03, Resolution **228**
**(Rev. WRC-03)** was modified to ask 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 systems, 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 No. **5.317A**;

And to conduct studies that consider:

-- the regulatory and technical issues associated with the use of
frequencies below those currently identified, including an assessment of
their advantages and disadvantages;

-- the needs of developing countries, including the use of the satellite
component of IMT-2000, for suitable coverage in these countries;

-   the results of sharing and compatibility studies with services to
    which the potential bands are already allocated

The need for the studies was driven by the perception that there may be
a need for new spectrum to accommodate:

-   the increasing demand for mobile services,

-   the development of higher bandwidth technologies, and

-   the potential to use mobile services to meet universal service
    requirements

The ITU-R WP 8F completed a Report on service types and their spectrum
requirements, and a Report that evaluates suitable frequency ranges
including in what timeframe such spectrum would be needed. WP 8F
finalized the spectrum calculation methodology for IMT systems and used
this to calculate spectrum estimates for IMT. The results of studies are
documented in the CPM Report, while other Reports and Recommendations
will be ready before WRC-07.

WP 8F decided on a new name for Systems Beyond IMT-2000, IMT-Advanced,
at their October 2005 meeting. It was also agreed that "IMT" would be
the root name and would encompass both IMT-2000 and IMT-Advanced
systems. The term IMT is recognized outside of the ITU, is simple, and
represents the services provided to users.

When considering the naming of IMT systems, one must also consider the
Radio Regulations and regulatory clarity. Generally, the Radio
Regulations (RR) allocate frequencies to Services (eg. Mobile, Fixed,
etc.) and these are, in some cases, further identified for certain
applications. Systems that meet the regulatory criteria in the frequency
band should not be limited in their evolution and there is no precedence
for limiting an allocation in the RR to a specific technology or
generation of technology. IMT-2000 is a set of technologies (as
described in Recommendation ITU-R M.1457), a specific generation of IMT,
which represents a unique situation in the RR.

The CPM text for Agenda Item 1.4 was completed at the 20^th^ meeting of
WP 8F and includes three methods to satisfy the agenda item. These are
concepts that may be applied to all or some of the candidate frequency
bands or a part of these bands. The Methods describe how footnotes would
reflect which IMT system(s) a specific frequency range is being
identified for.

Deploying cellular infrastructure is costly and time consuming therefore
being able to reuse existing infrastructure to expand the services
offered to users is essential. Advances in radio technology are allowing
operators to increase their capacity without increasing their spectrum
usage. As IMT-Advanced systems are being deployed it is important to
allow operators to expand or evolve their existing systems to offer
IMT-Advanced services within the bands that they are using for IMT-2000
where ever it is feasible.

The 2 700-2 900 MHz band is a major band for radiodetermination
services, either radionavigation or radiolocation (see **5.423**) and is
currently heavily used for Civil Aviation and Meteorological purposes,
all relating to safety of life and property.

Airport surveillance radars that operate in this band are crucial to the
safe and efficient operation of air travel worldwide. For many
administrations that currently may not use the band or use the band
lightly, loss of spectrum will also limit implementation of additional
airport surveillance radars and meteorological radars as the
requirements for deployment of additional systems continue to grow.

The 2 700-2 900 MHz band is also used by civil aviation radars for
medium range detection. Furthermore, in some administrations primary
radars, which were previously using the 1 215-1 300 MHz band, are now
progressively migrating into the 2 700-2 900 MHz band.

For some administrations, this band is used for civil aviation systems
(Aeronautical radionavigation) integrating Radiolocation and
Radionavigation in the same infrastructure. Operating experience shows
that any non-radar emissions in this band would significantly interfere
with existing systems and would seriously jeopardize the safety of life,
operations of civil aviation and radiolocation services. Moreover, the
high power necessary for civil aviation radionavigation radar systems,
makes the sharing of the band with IMT very difficult. ITU-R WP 8B
studies prior to WRC-2003, and more recently in preparation for WRC-07,
have concluded that sharing of IMT with radionavigation and
radiolocation in the band 2 700-2 900 MHz is clearly not feasible.

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.

**Reason:** Tropical climate countries that use 3625-4200 MHz band, due
to heavy rain conditions, don't have an alternative frequency band that
provides the same quality of service, and, in countries were this band
is extensively used, it is not possible to share the band with a service
that requires exclusion zones for the protection of the FSS terminals.

**Reason for opposition:** The Administration of Mexico has decided that
the use of band 3400-3700 MHz is for broadband Mobile and Fixed
Terrestrial Services, including International Mobile Telecommunications
(IMT). Administrations from other Regions of the ITU have stated their
intention of also identifying the segment 3600-3700 MHz for IMT, which
opens the possibility of having harmonized frequencies and the
subsequent generation of economies of scale.

**Reason:** The band 2700-2900 MHz is intensively used for Civil
Aviation and Meteorological purposes. ITU-R detailed analysis and
sharing studies undertaken by various ITU administrations and working
parties have shown that the utilization of the 2 700 - 2 900 MHz band by
IMT-2000 and IMT-Advanced systems is not feasible.

**Agenda Item 1.9**

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

**Proposals for agenda item 1.9**

Background information

The band 2 500-2 690 MHz is allocated to terrestrial and satellite
services. The terrestrial services allocations include Mobile and Fixed
services (including IMT-2000). Both services have been rapidly evolving
to encompass high speed mobile internet access requiring sensitive
receiving equipment some of which are highly susceptible to
interference.

WRC-03 recognized that there may be a need to revise technical,
operational and regulatory provisions applicable to the space services
in the band to accommodate the implementation of new innovative
technologies in the Fixed and Mobile services. To that end, WRC-03
developed and included this issue for consideration by WRC-07 (see
Agenda Item 1.9). Technical, operational and regulatory provisions
applicable to the use of the band 2500-2690 MHz by the following space
services are to be reviewed:

-   The fixed-satellite service which is subject to footnote **5.415**
    for the use of the bands 2 500-2 690 MHz in Region 2 and 2 500-2 535
    MHz and 2 655-2 690 MHz in Region 3, with the following condition of
    interest to Region 2:

1)  The use is limited to national and regional systems, subject to
    agreement obtained under No. **9.21**, giving particular attention
    to the broadcasting-satellite service in Region 1. In the direction
    space-to-Earth, the power flux-density at the Earth's surface shall
    not exceed the values given in Table **21-4**.

-   The mobile-satellite service which is subject to footnotes
    **5.351A**, **5.403**, **5.407**, **5.414**, **5.419** and
    **5.420**, with the following conditions of interest to Region 2:

1)  The use of the bands 2 500-2 520 MHz and 2 670-2 690 MHz refers to
    Resolutions **212** **(Rev.WRC-97)** and **225 (WRC-2000)**.

2)  The band 2 520-2 535 MHz (until 1 January 2005, the use of the band
    2 500-2 535 MHz) may also be used for Earth-to-space (except
    aeronautical mobile-satellite) and is limited to within national
    boundaries. The use is subject to agreement obtained under
    No.**9.2**1. The provisions of No.**9.11A** apply.

3)  The band 2 655-2 670 MHz (until 1 January 2005, the band 2 655-2 690
    MHz) may also be used for Earth-to-space (except aeronautical
    mobile-satellite) and is limited to within national boundaries. This
    use is subject to agreement obtained under No.**9.21** and the
    provisions of No**.9.11A** apply.

4)  After 1 January 2005, the allocation of the band 2 500-2 520 MHz
    shall be effective for space-to-Earth and is subject to coordination
    under No.**9.11A**

5)  After 1 January 2005, the allocation of the band 2 670-2 690 MHz
    shall be effective. When introducing systems in this band,
    Administrations shall take all necessary steps to protect the
    satellite systems operating in this band prior to 3 March 1992. The
    coordination shall be in accordance with No.**9.11A.**

6)  In the band 2 500-2 520 MHz, the power flux-density at the surface
    of the Earth from space stations operating from space-to-earth shall
    not exceed -152 dB(W/(m2 ∙ 4 kHz)) in Argentina, unless otherwise
    agreed by the Administrations concerned.

-   The aeronautical mobile-satellite service which is subject to
    footnotes **5.415A** and **5.420A**.

-   The broadcasting-satellite service which is subject to footnotes
    **5.416**, **5.418**, **5.417A**, **5.417B**, **5.417C**,
    **5.417D**, **5.418A**, **5.418B**, and **5.418C** with the
    following condition of interest to Region 2:

1)  The use of the band 2 520-2 670 MHz by the broadcasting-satellite
    service is limited to national and regional systems for community
    reception, subject to agreement obtained under No. **9.21**.

-   The radiodetermination-satellite service which is subject to
    footnote **5.404**.

Within the terrestrial mobile service, the use of the band by IMT-2000
is subject to footnote **5.384A**. This band is identified for use by
Administrations wishing to implement IMT-2000 in accordance with
Resolution **223 (WRC-2000)**.

There are concerns that terrestrial service may suffer constraints, such
as reduction of cell coverage, a consequential increase in the number of
base stations and the cost of infrastructure that may have a large
economic impact.

Regarding CITEL activities, PCC.II/Recommendation 8 (IV-04) was approved
in the IV meeting of PCC II, in December 2004. This Recommendation
establishes the following frequency arrangement for IMT-2000 in the band
2 500-2 690 MHz, among others, noting that there is no intention to
implement MSS in this band:

Administrations in Region 2 are planning for implementation of
terrestrial services in the 2 500-2 690 MHz band. There are no known
plans to provide MSS in Region 2.

**Reasons:** Studies have shown that a satellite pfd value of -136
dBW/m^2^/MHz at angles below 5, and -122 dBW/m^2^/MHz at angles greater
than 25 yielded acceptable levels of interference to terrestrial
services in the 2500-2690 MHz band. The proposed power flux density
limits would facilitate FSS, BSS and MSS sharing with current and future
terrestrial services in the band 2500-2690 MHz and provide necessary
safeguard for the terrestrial (FS and MS) systems in the band. The
proposed modification would also provide regulatory certainty to
satellite services as a defined set of pfd limits would be known and
extensive coordination with uncertain outcome would not be required.
