2、roup “Spectrum Engineering” (WGSE) Text of the Recommendation adopted by the “European Radiocommunications Committee” (ERC): “The European Conference of Postal and Telecommunications Administrations, considering 1) that CEPT has a long term objective to harmonise the use of frequencies throughout Eu
3、rope, 2) that CEPT should develop radio frequency channel arrangements in order to make the most effective use of the spectrum for point to point (P-P), point to multipoint (P-MP) and ENG/OB applications, 3) that CEPT/ERC Kecommendation 25-10 designates this band as a tuning range for ENGOB, 4) that
4、 the band 3400 MHz to 3410 MHz is used by land, airborne and naval military radars, 5) that the achievement of harmonisation requires the adoption of a limited number of channel arrangements, noting a) that the table of frequency allocations in the Radio Regulations allocates the band 3400 MHz to 36
5、00 MHz on a primary basis to the Fixed and Fixed - Satellite services and on a secondary basis to the Radiolocation and Mobile services, b) that countries desire to deploy different combinations of 1-P, P-MP and ENG/OB systems on a primary basis in this band with duplex spacings, if appropriate, of
6、50 MHz or 100 MHz, c) that there is an ITU-R Recommendation (F-635) for P-P wide band applications incorporating this band for some administrations, d) that frequency separation may be required for uncoordinated deployment of current and future systems, e) that cellular deployment of P-MP systems pr

Where the band 3410 MHz - 3600 MHz is shared between ENG/OB and P-P or P-MP services by an administration, ENG/OB services will operate within either the range 3410 MHZ - 3500 or 3500
11、 MHz - 3600MHz, with P-P and P-MP services in the other part of the band, to minimise Co-ordination problems between the services.
