Agenda Item | Description |
Agenda 1.11 | This agenda item relates to proposals to provide broadcast satellite services in the band 620 - 790 MHz, from GSO or non-GSO stations. This band is extensively used by terrestrial applications, in particular terrestrial television broadcasting, and it is therefore necessary to undertake studies of sharing including the sharing criteria, together with regulatory provisions. It should be noted that article 22.2 applies in this band, and so study will be required to ensure that non-GSO BSS systems do not cause unacceptable interference into GSO systems. These bands also have allocations to the fixed and mobile services in some regions, which results in additional scenarios that require study. |
Agenda 1.13 | This agenda item covers issues relating to all services in HF bands between 4 MHz and 10 MHz, excluding those in the band 7 000 - 7 200 kHz and those covered by Appendices 25, 26, and 27. Technological change has made bands allocated for A1A Morse telegraphy and narrow band direct printing under utilised, while there is a demand for new digital technology and more spectrum for broadcast applications. Studies are therefore required to: i) continue to study under Resolution 729 the use of frequency adaptive systems in the MF and HF bands; ii) identify the characteristics of digital system(s) to be used in the MF/HF bands by the maritime mobile service, taking into account MMS requirements and impact on Appendix 17; iii) study the potential to allocate further bands to the broadcast service, taking into account other services using these bands |
Resolution 21 | This resolution relates to impact of allocating the bands between 5 900 to 19 020 kHz which had allocations for mobile and fixed to the broadcast service. Any existing mobile or fixed service will therefore require to be reallocated. The Resolution calls on procedures at the BR to handle this over the transition period up to 1st April 2007. |
Resolution 517 | This resolution relates to the introduction of digitally modulated and single-sideband (SSB) emissions in HF bands between 5 900 kHz and 26 100 kHz allocated to the broadcasting service. It encourages the use of digital and SSB techniques over double-sideband emissions, and continuation of ongoing studies in the ITU-R on digital HF broadcasting. |
Resolution 535 | This resolution relates to the development of software or set of software modules to support the application of Article 12 in the undertaking compatibility, service area and reliability analysis of broadcasting services in the HF bands. The software is to be developed by the BR with support from administrations. |
Resolution 543 [COM4/1] | This resolution relates to protection ratios to be used for seasonal planning of HF systems for sharing between AM and digital, or between digital systems. It calls upon further studies to revise if required the values given. |
