Agenda Item Text of Agenda Item Conclusion and/or Recommendation of the Committee
1.20 To consider the results of ITU R studies and spectrum identification for gateway links for high altitude platform stations (HAPS) in the range 5 850-7 075 MHz in order to support operations in the fixed and mobile services, in accordance with Resolution 734 (Rev.WRC 07). Recommendation: Unwanted emissions should be low enough to meet the levels of Recommendation ITU-R RA.769 in Radio Astronomy Service frequency allocations if HAPS platforms are deployed within range of radio astronomy observatories.

Recommendation: Spectrum selected for HAPS gateway links should avoid frequencies used for Earth observation by current and planned remote-sensing satellites in accordance with ITU Footnote 5.458.
