-The band 3400-4200 MHz is allocated to the Fixed service on a primary basis

-The band 1427-1435 MHz is also allocated to other services as follows:

3400-3500: FIXED-SATELLITE (space-to-Earth), Amateur, Mobile, Radiolocation

3500-3700: FIXED-SATELLITE (space-to-Earth), MOBILE except aeronautical mobile, Radiolocation

3700-4200: FIXED-SATELLITE (space-to-Earth), MOBILE except aeronautical mobile

-Channel arrangement for microwave systems in the band 3400-3800 MHz is under consideration

a/

NOTE:

·This radio-frequency channel arrangement complies with Recommendation ITU-RF.382-6, 1997

·Application: point-to-point microwave systems

·Transmission capacity: 2x34 Mbps, 600 FDM channels

·Minimum transmission distance: 30 km

·The centre frequencies in MHz of individual channels are expressed by the following relationships:

fn = fo - 237 + 58n     fo= 4003,5MHz

f^’n = fo - 24+ 58n       n = 1, 2, 3
