Methodologies for interference evaluation from the downlink of the fixed service using high altitude platform stations to the uplink of the fixed-satellite service using the geostationary satellites within the band 27.5-28.35 GHz Questions ITU-R 218/9 and
This Annex provides a methodology for interference evaluation from the FS using HAPS to a GSO
satellite system in the FSS within the band 27.5-28.35 GHz. This band is used for the Earth-tospace
(uplink) direction by the GSO/FSS system.
