  COMMON Proposal for the work of the Conference   

  Agenda item 1.4                                  

  Assessment of the possible impact of IMT         
  identification in the band 470-862 MHz on\       
  the digital terrestrial broadcasting service and 
  other primary services                           
  ------------------------------------------------ ----------------------------------------------------

In the RCC countries, the band 470-862 MHz is currently intensively used
for the broadcasting and other primary services. In the broadcasting
service, moreover, the transition from analogue to digital broadcasting
is being carried out in accordance with the digital frequency Plan of
the Geneva-06 Agreement, and this will result in the need for additional
frequency channel usage and create a situation of near full usage of the
entire frequency band 470-862 MHz.

Studies on the impact on the Geneva-06 Plan of a primary allocation to
the mobile service in the band 470-862 MHz and on the possibility of
identifying harmonized sub-bands for IMT mobile systems have not yet
been completed. This being the case, a breach of electromagnetic
compatibility could occur between IMT and existing systems in that band.

The RCC countries are therefore of the view that any decision on
identification of the band 470-862 MHz or parts thereof must be based on
detailed technical and regulatory studies, particularly studies of
electromagnetic compatibility between IMT systems and the radio
facilities of the terrestrial broadcasting service and of other primary
services. Such studies are already being carried out in ITU-R, in
regional organizations and at the national level, although not all of
the issues are as yet being covered.

The RCC countries have analysed the possible impact of identifying the
band 470-862 MHz or parts thereof on the Geneva-06 digital Plan, as well
as the difficulties that could arise on account of the need to protect
the radio facilities of other primary services used in the RCC
countries.

Table 1 and Figures 1 to 3 show the change in the number of available
frequency allotments and reduction in the number of coverages in the
Geneva-06 digital Plan for different identification scenarios in the
band in question for IMT. Broadcasting service losses within the
radio-frequency spectrum may be from 10 to 40 per cent (see Table 1),
resulting in a reduction in the number of coverages in the Geneva-06
digital Plan on average from 7-8 to 3-4 (see Figures 1 to 3). This will
present the RCC countries with considerable difficulties for the future
development of the broadcasting service, particularly when it comes to
expanding the number of programmes transmitted and introducing HDTV.

Table 2 and Figures 4 to 6 show the number of frequency assignments to
the fixed service and aeronautical radionavigation service in the band
470-862 MHz requiring protection in the RCC countries under the
Geneva-06 Agreement. As will be seen from the said table and figures,
the considerable number of assignments indicated and significant
requirements in terms of their protection will result in substantial
difficulties when it comes to introducing IMT systems in neighbouring
countries for all 470-862 MHz identification scenarios for IMT.

RCC/16A2/1

On the basis of their analysis, the RCC administrations do not support
allocation of the band 470‑862 MHz to the mobile service and its
identification at WRC‑07, but support the need to conduct additional
studies in the period leading up to the next competent conference.
