This Recommendation provides maximum e.i.r.p. density of transmitting hub and subscriber point-to-multipoint stations in the fixed service towards the direction of the geostationary-satellite orbit to enable sharing with the inter-satellite service in the band 25.25-27.5 GHz. The reference e.i.r.p. density in this Recommendation takes into account the need for transmission at the minimum necessary level while taking into account use of automatic transmitter power control (ATPC) at the fixed service (FS) stations for precipitation events.
