Impact of uplink transmission in the fixed service usign high altitude platform stations on the Earth exploration-satellite service (passive) in the 31.3-31.8 GHz band
This Recommendation provides guidance on the interference evaluation method of high altitude platform stations (HAPS) uplink on the EESS (passive) in the 31.3-31.8 GHz band. Annex 1 provides considerations on a limit for the level of unwanted emissions of a transmitter at the input of a HAPS ground station antenna using the typical parameters for the HAPS system in the band 31-31.3 GHz given in Recommendation ITU-R F.1569.
