RES555 – 354 – MOD RESOLUTION 555 (REV.WRC-15) Additional regulatory provisions for broadcasting-satellite service networks in the frequency band 21.4-22 GHz in Regions 1 and 3 for the enhancement of equitable access to this frequency band The World Radiocommunication Conference (Geneva, 2015), considering a) that WARC-92 allocated the frequency band 21.4-22 GHz in Regions 1 and 3 to the broadcasting-satellite service (BSS) to be implemented after 1 April 2007; b) that the use of the frequency band since 1992 was subject to an interim procedure in accordance with Resolution 525 (WARC-92, Rev.WRC-03 and Rev.WRC-07); c) that Article 44 of the ITU Constitution sets out the basic principles for the use of the radio-frequency spectrum and the geostationary-satellite and other satellite orbits, taking into account the needs of developing countries, further considering a) that a priori planning for BSS networks in the frequency band 21.4-22 GHz in Regions 1 and 3 is not necessary and should be avoided as it freezes access according to technological assumptions at the time of planning and then prevents flexible use taking account of real world demand and technical developments; b) that interim arrangements for the use of the frequency bands were on a first-come first-served basis, recognizing a) that the number of filings made by some administrations in this frequency band is extremely large, which may not be realistic and may be difficult to implement within the regulatory time-limit under Article 11; b) that the number of filings (291 coordination requests received by the Bureau as at December 2011), including those referred to in recognizing a) above, is limiting the possibility of successful coordination of BSS systems already submitted or planned to be submitted by other administrations, resolves 1 to urge administrations to make the utmost efforts to accommodate submissions received from other administrations with few filings, especially covering their own territories;
