AP7 – 103 – Notes to Table 8c: 1 A: analogue modulation; N: digital modulation. 2 E is defined as the equivalent isotropically radiated power of the interfering terrestrial station in the reference bandwidth. 3 In this band, the parameters for the terrestrial stations associated with transhorizon systems have been used. If an administration believes that transhorizon systems do not need to be considered, the line-of-sight radio-relay parameters associated with the frequency band 3.4-4.2 GHz may be used to determine the coordination area. 4 Digital systems assumed to be non-transhorizon. Therefore Gx = 42.0 dBi. For digital transhorizon systems, parameters for analogue transhorizon systems above have been used. 5 These values are estimated for 1 Hz bandwidth and are 30 dB below the total power assumed for emission. 6 In certain systems in the fixed-satellite service it may be desirable to choose a greater reference bandwidth B. However, a greater bandwidth will result in smaller coordination distances and a later decision to reduce the reference bandwidth may require recoordination of the earth station. 7 Geostationary-satellite systems. 8 Non-geostationary satellites in the meteorological-satellite service notified in accordance with No. 5.461A may use the same coordination parameters. 9 Non-geostationary satellite systems. 10 Space research earth stations in the frequency band 8.4-8.5 GHz operate with non-geostationary satellites. 11 For large earth stations: Pr(p) = (G − 180) dBW For small earth stations: Pr(20%) = 2 (G − 26) − 140 dBW for 26 < G 29 dBi Pr(20%) = G − 163 dBW for G 29 dBi Pr(p)% = G − 163 dBW for G 26 dBi 12 Applies to the broadcasting-satellite service in unplanned bands in Region 3.
