                        Regulatory status of terrestrial repeaters
                        within Satellite component of IMT-2000


1      Background
At the Brussels meeting of ECC PT1 the concept of S-DMB was presented by Alcatel. It has
been observed that this satellite concept (amongst others) includes the use of terrestrial
repeaters as part of the satellite system. The aim of such terrestrial repeaters is to achieve
coverage in areas where full coverage by satellite emission is not possible due to path
obstructions and in-house penetration loss. It has been described that such repeaters may be
fed by
     using the same frequency bands, not allocated to FSS,
     using FSS allocated frequency bands,
     Other media like terrestrial FS links or cable/fibre optics applications.

From a regulatory perspective the status of such terrestrial repeaters, envisaged as terrestrial
transmitting base stations for systems of satellite component of IMT-2000 has to be clarified.



2     Proposal
ECC PT1 shall take the following decision and contribute this view to ITU-R WP8F as the
CEPT position on the regulatory status of terrestrial repeaters within Satellite component of
IMT-2000:

       Terrestrial repeaters within satellite systems will operate for the transmitting part
       under the Mobile Service allocation. Any IMT-2000 concept using base station
       transmitter or receiver on the surface of the earth is part of terrestrial component of
       IMT-2000 only. This includes in particular the operation of terrestrial repeaters
       independently from their way of feeding via satellite or by terrestrial means. Hence, If
       satellite systems are considered to be within the IMT-2000 family the transmitting part
       of repeaters will be part of terrestrial component of IMT-2000 only.
       As a consequence, such applications must be in full compliance with the Radio
       Regulations (RR) and the detailed frequency arrangements of terrestrial component of
       IMT-2000 in the 2500-2690 MHz band as to be defined by the revision of ECC
       Decision[XXX], and ITU-R Recommendation M.1036 accordingly, planned for the
       year 2004. Any restriction in terms of flexibility and possible options in the 2500-2690
       MHz band caused by the introduction of repeater concepts is totally unacceptable.
