RES528 – 329 – MOD RESOLUTION 528 (REV.WRC-15) Introduction of the broadcasting-satellite service (sound) systems and complementary terrestrial broadcasting in the frequency bands allocated to these services within the range 1-3 GHz The World Radiocommunication Conference (Geneva, 2015), considering a) that WARC-92 has made frequency allocations to the broadcasting-satellite service (sound) and complementary terrestrial broadcasting; b) that it is necessary to ensure that the introduction of the broadcasting-satellite service (sound) and complementary terrestrial broadcasting proceeds in a flexible and equitable manner; c) that efficient use of the spectrum will be enhanced by a worldwide allocation; d) that a worldwide allocation may cause difficulties to some countries in relation to their existing services; e) that future planning may limit the effect on other services, resolves 1 that a competent conference should be convened for the planning of the broadcasting-satellite service (sound) in the frequency bands allocated to this service in the range 1-3 GHz; and the development of procedures for the coordinated use of complementary terrestrial broadcasting; 2 that this conference should review criteria for sharing with other services; 3 that in the interim period, broadcasting-satellite systems may only be introduced within the upper 25 MHz of the appropriate frequency band in accordance with the procedures contained in Sections A to C of Resolution 33 (Rev.WRC-15), or in Articles 9 to 14, as appropriate (see resolves 1 and 2 of Resolution 33 (Rev.WRC-15)). The complementary terrestrial service may be introduced during this interim period subject to coordination with administrations whose services may be affected; 4 that the calculation methods and the interference criteria to be employed in evaluating the interference should be based upon relevant ITU-R Recommendations agreed by the administrations concerned as a result of Resolution 703 (Rev.WRC-07) or otherwise, invites the ITU-R to conduct the necessary studies prior to the conference, instructs the Secretary-General to bring this Resolution to the attention of the Council to consider including in the agenda of a radiocommunication conference the matters addressed above.
