C Band: The uplink frequencies ranged from 5925 to 6425 MHz. The downlink frequencies ranged from 3700 to 4200 MHz, providing 500 MHz of bandwidth in each direction. This freq region is overlaps with terrestrial microwave communication systems.. This situation causes interference between C-Band and terrestrial microwave communication systems. Since these terrestrial systems existed prior to the development of satellite communication systems, the newer satellite systems must not interfere with the terrestrial systems. Therefore, the EIRP is limited to a level so that there is no interference from the satellite with the terrestrial system. Also, the locations of the uplink earth-stations need to be restricted to prevent interference with terrestrial microwave communication systems.
