RES760 – 409 – 1 Case of mobile service usage under the frequency allocation plans when base stations transmit only in the frequency band 758-788 MHz and receive signals only in the frequency band 703-733 MHz TABLE 1 ARNS station System type code Coordination distances for the receiving MS base stations (km) Coordination distances for the transmitting MS base stations (km) RSBN (ground receiver) AA8 – 70/125/175* * 90% ≤ land path ≤ 100% / 50% ≤ land path < 90% / 0% ≤ land path < 50%. 2 Other cases TABLE 2 ARNS station System type code Coordination distances for the receiving MS base stations (km)** Coordination distances for the transmitting MS base stations (km) RSBN AA8 50 125/175* RLS 2 (type 1) (airborne receiver) BD 410 432 RLS 2 (type 1) (ground receiver) BA 50 250/275* RLS 2 (type 2) (airborne receiver) BC 150 432 RLS 2 (type 2) (ground receiver) AA2 50/75* 300/325* RLS 1 (types 1 and 2) (ground receiver) AB 125/175* 400/450* Other ARNS ground stations Not applied 125/175* 400/450* Other ARNS airborne stations Not applied 410 432 * 50% ≤ land path ≤ 100% / 0% ≤ land path < 50%. ** Coordination distances for the receiving MS base stations are based on protection of ARNS stations from the stations in the mobile service and do not ensure protection for receiving base stations of MS from ARNS stations.
