RES749 – 397 – ANNEX 1 TO RESOLUTION 749 (REV.WRC-15) The criteria for identifying potentially affected administrations with respect to the aeronautical radionavigation service in countries listed in No. 5.312 To identify potentially affected administrations when applying the procedure for seeking agreement under No. 9.21 by the mobile service with respect to the aeronautical radionavigation service (ARNS) operating in countries mentioned in No. 5.312, as stipulated in No. 5.316B, the coordination distances (between a base station in the mobile service and a potentially affected ARNS station) indicated below should be used. When applying No. 5.316B, notifying administrations may indicate in the notice sent to BR the list of administrations with which bilateral agreement has already been reached. BR shall take this into account in determining the administrations with which coordination under No. 9.21 is required. 1 Case where the mobile service is operated according to the frequency arrangement where the base stations transmit only in the frequency band 791-821 MHz and receive only in the frequency band 832-862 MHz ARNS station System type code Coordination distances for receiving base stations of MS (km) Coordination distances for transmitting base stations of MS (km) RSBN (ground receiver) AA8 - 70/125/175** RLS 2 (Type 2) (aircraft receiver) BC 70/150* - RLS 1 (Types 1 and 2) (ground receiver) AB 70/125/175** - * Тhe first value should be used when the notifying administration indicates in the notice form that aggregate e.i.r.p. value of all user equipment operating simultaneously with the notified base station is assumed not to exceed 21 dBm in 1 MHz. The second value should be used in other cases. ** 90% ≤ land path ≤ 100% / 50% ≤ land path < 90% / 0% ≤ land path < 50%.
