  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)**

Resolution 228 (Rev.WRC-03) -- Studies on frequency-related matters for
the future development of IMT‑2000 and systems beyond IMT‑2000 as
defined by ITU-R

AFCP/43A3/1

The African administrations do not support the identification of the
410-430 MHz band for IMT systems.

**Reasons:** This band is heavily used in many African countries by
other land mobile services including public protection and disaster
relief systems.

AFCP/43A3/2

The African administrations support the identification of the
450-470 MHz band for IMT systems.

**Reasons:** This band has better propagation characteristics when
compared to higher frequency bands, and would provide coverage of large
territories with low subscriber density, which are typically found in
Africa. Moreover, in some countries, IMT-2000 networks have been
deployed in this band and equipment is commercially available in this
band.

AFCP/43A3/3

The African administrations do not support the identification of the
470-806 MHz band for IMT systems.

**Reasons:** This band is currently used for analogue television
terrestrial broadcasting services and consequently for digital
terrestrial television as a result of the RRC-06 Conference, which
established the new digital broadcasting plan and which must be
protected.

AFCP/43A3/4

The African administrations support the allocation of the band 806-862
MHz for the mobile service on a primary basis and its identification for
IMT.

**Reasons:** This band will allow the deployment of large cells which
will facilitate the deployment of advance services in rural low density
areas.

AFCP/43A3/5

The African administrations support the identification of the
2 300-2 400 MHz bands for IMT systems.

**Reasons:** In many African countries, the 2 300-2 400 MHz band is
allocated for fixed services including wireless access systems on a
shared, non-protected basis subject to guidelines issued by the
regulators. This band is near the bands already identified for IMT-2000
and would present similar propagation characteristics. This could be
beneficial for reducing the complexity of the equipment. In some
countries, IMT-2000 networks have already been or are being deployed in
this band.

AFCP/43A3/6

The African administrations do not support the identification of the
2 700-2 900 MHz bands for IMT systems.

**Reasons:** The 2 700-2 900 MHz band is allocated on a primary basis
and used for aeronautical radionavigation, a safety-of-life service, in
all three ITU-R Regions. Sharing studies are currently being progressed
within ITU-R to investigate sharing between the aeronautical
radionavigation service (ARNS) and meteorological radars and IMT-2000
and beyond IMT-2000 systems in the 2 700-2 900 MHz band. Interference
simulations between incumbent radars operating in the band 2 700‑2 900
MHz and IMT-2000 systems show that interference will occur to ARNS and
meteorological radars on a co-channel basis. Analysis of interference
from radars into IMT networks show that interference will be present
even at distances of hundreds of kilometres.

Proposals regarding the band 3 400-4 200 MHz

The African countries support no change for the band 3 400-4 200 MHz,
with the exception for the band 3 400-3 600 MHz, where countries listed
in footnote 5.A04 below propose an upgrade of the mobile service
allocation to the primary status and an identification for IMT.

**ADD** AFCP/43A3/8

**5.A04** In the following countries, Botswana, Côte d'Ivoire, Lesotho,
Malawi, Mozambique, Namibia, Sierra Leone, Swaziland, Zambia and
Zimbabwe, the band 3 400-3 600 MHz is allocated to the mobile service on
a primary basis and is identified for IMT.

**Reasons:** This band is used by stations in the fixed and
fixed-satellite services in all regions. In Africa, there is extensive
deployment of FSS earth stations. This band is important for FSS because
atmospheric absorption is lower in this band thus improving reliability
and coverage, particularly in case of severe rain fade conditions which
are typical in Africa.

AFCP/43A3/9

The African administrations do not support the identification of the
band 4 400-4 990 MHz for this agenda item.

**Reasons:** The deployment of FSS in the band 4 500-4 800 MHz including
the Appendix 30B Allotment Plan will likely be constrained.

AFCP/43A3/10

The African administrations support the identification of the bands 1
518-1 525 MHz and 1 668-1 675 MHz for the satellite component of IMT
systems. This could be done by adding the bands to footnote No. 5.351A
and modification of Resolution 225 (Rev.WRC-03).

**Reasons:** This would partially increase the spectrum available for
MSS systems, which are part of the satellite component of the IMT
family. It would also provide consistent regulatory provisions in the
1-3 GHz range, which would apply to MSS systems wishing to provide
IMT-2000 services in the bands 1 518-1 525 MHz and 1 668-1 675 MHz in
conjunction with services in other nearby MSS bands.

AFCP/43A3/11

In order to satisfy spectrum requirements for the terrestrial component
of this agenda item, the African administrations support Method 1 that
is based on the assumption that IMT is the root name for both IMT-2000
and IMT-Advanced and the technologies associated with those terms. This
method calls for existing IMT-2000 spectrum to be identified generically
for IMT, and any additional spectrum could be identified generically for
IMT in the Radio Regulations. The additional IMT spectrum should come
from spectrum with a primary mobile allocation in Article 5 or a new
primary allocation to mobile. A regulatory footnote should be used to
identify the specific frequency bands for IMT such that the existing
IMT-2000 spectrum should be identified generically for IMT and any
additional spectrum should be identified generically for IMT in the RR.
