TABLE ES.1 WRC-12 Agenda Items of Relevance and Potential Impact to RAS and EESS and the Associated Conclusions and Recommendations of the Committee

Agenda Item Text of Agenda Item Conclusion and/or Recommendation of the Committee
1.3 To consider spectrum requirements and possible regulatory actions, including allocations, in order to support the safe operation of unmanned aircraft systems (UAS), based on the results of ITU-R studies, in accordance with Resolution 421 (WRC 07). Recommendation: Transmissions in support of unmanned aircraft in the 5030-5150 MHz band should have a sufficiently low level of unwanted emissions to avoid interference in the adjacent Radio Astronomy Service bands in accord with Recommendation ITU-R RA.769.
1.4 To consider, based on the results of ITU R studies, any further regulatory measures to facilitate introduction of new aeronautical mobile (R) service (AM(R)S) systems in the bands 112-117.975 MHz, 960-1 164 MHz and 5 000-5 030 MHz in accordance with Resolutions 413 (Rev.WRC 07), 417 (WRC 07) and 420 (WRC 07). Recommendation: Transmitters providing surface applications at airports in the 5000-5030 MHz band should have sufficient suppression of out-of-band emissions to avoid interference in the adjacent 5 GHz Radio Astronomy Service band in accord with Recommendation ITU-R RA.769.
1.6 To review No. 5.565 of the Radio Regulations in order to update the spectrum use by the passive services between 275 GHz and 3 000 GHz, in accordance with Resolution 950 (Rev.WRC 07), and to consider possible procedures for free-space optical-links, taking into account the results of ITUR studies, in accordance with Resolution 955 (WRC 07). Recommendation: Administrations should protect the bands given in Tables 2.1 and 2.2 from harmful interference so they may be used by the Radio Astronomy Service and Earth Exploration-Satellite Service, respectively.
1.7 To consider the results of ITU R studies in accordance with Resolution 222 (Rev.WRC 07) in order to ensure long-term spectrum availability and access to spectrum necessary to meet requirements for the aeronautical mobile-satellite (R) service, and to take appropriate action on this subject, while retaining unchanged the generic allocation to the mobile-satellite service in the bands 1 525 1 559 MHz and 1 626.5-1 660.5 MHz. Recommendation: AM(R)S transmissions in the overlapping and adjacent bands should have out-of-band emissions below –237 dBW/(m2Hz) at registered Radio Astronomy Service sites, in accordance with Recommendation ITU-R RA.769 for spectroscopic observations.
1.8 To consider the progress of ITU R studies concerning the technical and regulatory issues relative to the fixed service in the bands between 71 GHz and 238 GHz, taking into account Resolutions 731 (WRC 2000) and 732 (WRC 2000)” Recommendation: Administrations are urged to protect the passive services from harmful interference in 71-238 GHz. Per Tables 2.4 and 2.5, this band is extremely important for a wide range of scientific problems, both for Radio Astronomy Service and Earth Exploration-Satellite Service.
