Agenda Item	Description
Agenda 1.4	This wide ranging Agenda Item relates to the further development of IMT-2000 and systems beyond IMT-2000, in particular: i) studies of the requirements for spectrum and potential frequency ranges ii) consideration of spectrum at frequencies below those identified in 5.317A (806 - 960 MHz) iii) that the studies in i) above should take account of benefit to developing countries of the satellite component of IMT-2000; iv) that sharing and compatibility studies should be performed where necessary when considering additional frequency bands for IMT-2000
Agenda 1.6	This agenda item relates to aeronautical mobile (R) services in bands between 108 MHz and 6 GHz. It notes there are new requirements to support air navigation, and so the following work is required: i) to identify if existing allocations to aeronautical services are sufficient for these new applications; ii) if additional spectrum is required, to identify what might be suitable bands, taking into account the need to not constrain existing and planned use of such bands, and so undertaking sharing studies where required; iii) in particular, how to accommodate the requirements for aeronautical systems in the band 5 091 - 5 150 MHz iv) to consider what actions would be required to broaden current satellite frequency allocations to support the expansion of the ICAO CNS/ATM system
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
Agenda 1.17	This agenda item relates to the 1 390 - 1 392 MHz (E-s) and 1 430 - 1 432 MHz (s-E) additional allocations made during WRC 2003 to the fixed satellite service operating feeder links for non-GSO MSS systems where the service links are under 1 GHz. However the CPM Report indicated that studies of compatibility with other services allocated in this band were not complete, indeed there were suggestion that sharing with EESS (passive) in particular, could be problematic. Services in these bands includes the fixed, mobile, radiolocation, EESS (passive), radio astronomy, space research (passive) and aeronautical mobile. These allocations are therefore not be used until studies are completed on: i) sharing studies on operational and technical means to facilitate sharing in the uplink direction in the band identified and others around 1.4 GHz; ii) sharing studies on operational and technical means to facilitate sharing in the downlink direction in the band identified and others around 1.4 GHz; iii) validate that the unwanted emissions from the FSS feeder links would meet the protection requirements of the passive services iv) to study the PFD levels required to protect the EESS (passive)
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 63	This resolution relates to interference from industrial, scientific, and medical (ISM) equipment, and calls for further studies on the limits to be imposed on ISM equipment within and outside the bands designated for its use.
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 734	This resolution relates to the feasibility of use of high altitude platform stations (HAPS) in fixed and mobile service bands above 3 GHz allocated exclusively for terrestrial applications. It calls for regulatory and technical studies of methods to facilitate use of HAPS in these bands, taking into account terrestrial services in-band and other services in adjacent bands.
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.
Resolution 413 [COM5/2]	This resolution relates to the use of the band 108 - 117.975 MHz by aeronautical services, where new applications are being considered. In addition new digital sound broadcasting systems are planned to be introduced in the band 87 - 108 MHz. However no compatibility criteria exist between these two services. Therefore there is the need for further study of any compatibility issues relating to these services and frequency bands.
Resolution 646 [COM5/4]	This resolution relates to protection and disaster relief. It notes many of the factors relating to the requirements and issues relating to provision of such safety of life services. It calls for studies into: i) technical and operational implementation of advanced solutions to the needs of protection and disaster relief; ii) further technical studies in support of possible additional identification of other frequency bands to meet the needs of certain countries in Region 1.
Resolution 951 [COM7/2]	This resolution is related to the issue of terrestrial wireless interactive multimedia (TWIM) systems, that could operate across traditional service boundaries, using a range of emerging technologies. It calls for studies to examine the effectiveness, appropriateness, and impact of the Radio Regulations with respect to these new systems. The results of these studies are to be included in the Director of the BR's Report to WRC-07 to allow consideration of this subject on a future conference agenda. See also WRC-03 Recommendation 722 [COM7/2]
Resolution 952 [COM7/3]	This resolution relates to the issue of Ultra Wide-band (UWB) systems, that have a very large bandwidth and so could operate across many frequency bands, potentially impacting a large number of receivers. These systems are not considered as Industrial, Scientific, and Medical (SIM) applications. There is therefore a need to continue studies about the issues raised by these systems, including sharing studies and regulatory procedures.
