The ITU Radiocommunication Assembly considering a) that the frequency bands 11-14 GHz and 20-30 GHz are available to systems in the fixed-satellite service (FSS) employing satellites in both geostationary (GSO) and non-GSO orbits; b) that earth stations in the FSS employing satellites in GSO orbits need to be protected from unacceptable interference by satellites in non-GSO orbits transmitting in the shared frequency bands; c) that in order to provide the requisite protection from such interference, the World Radiocommunication Conference (Istanbul, 2000) (WRC-2000) adopted validation single-entry limits on the maximum permissible equivalent power flux-densities (epfd) which satellites in non-GSO orbits may radiate in some frequency bands, for certain specified earth station antenna diameters.
