| Agenda Item | Description |
|---|---|
| Agenda 1.1 | Deletion from footnotes in S5 |
| Agenda 1.2 | This agenda item refers to three issues relating to EESS (passive) and the GSO meteorological satellite service: i) consider whether it would be feasible for WRC 2007 to extend the allocation for GSO meteorological satellite service between 18.1 and 18.3 GHz to provide 300 MHz of contiguous spectrum; ii) to determine appropriate sharing criteria between EESS (passive) and SRS (passive) and the fixed and mobile services in the 10.6 - 10.68 GHz band; and iii) to determine suitable criteria for EESS (passive) to share the 36 - 37 GHz band with fixed and mobile services, in particular high density point to point fixed services |
| Agenda 1.3 | This agenda item refers to bands between 9 and 10 GHz, where requirements have been identified for more spectrum to be available for: i) radiolocation, by raising its status in the 9 200 - 9300 MHz from secondary to primary, to be used in conjunction with existing primary allocations which include the 9 000 - 9 200 MHz and 9 300 - 9 800 MHz bands; ii) EESS, by allocating up to 200 MHz of additional spectrum around a current allocation at 9 500 - 9 800 MHz |
| 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 1.5 | This agenda item covers consideration of mobile allocations to be used for wideband aeronautical telemetry and associated telecomand, based upon: i) study of the spectrum requirements for such systems; ii) study of possible upgrading of suitable secondary mobile allocations in the range 3 - 16 GHz to primary, undertaking sharing studies where required; iii) consideration of additional allocations in the range 3 - 16 GHz to the mobile service for such services, undertaking sharing studies where required; |
| 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 1.7 | This agenda item relates issues relating to the allocation of 7 MHz to the MSS (Earth to space) between 1 668 MHz and 1 675 MHz. Outside the US (where MSS operation is unlikely to be feasible), there is a need to study: i) studies relating to sharing with space research (passive) space stations in the 1 668 - 1 668.4 MHz band, and ii) studies relating to sharing with the mobile service, in the band 1 668.4 MHz to 1 675 MHz In these bands there are also allocations for the fixed, meteorological, met aids, and radio astronomy services |
| Agenda 1.8 | This agenda item relates to continuing the development of the regulatory framework for High Altitude Platform Stations (HAPS). Firstly in the bands 47.2 - 47.5 and 47.9 - 48.2 GHz: i) to encourage administrations to facilitate coordination between HAPS systems and co-primary satellite services, provisionally using Article 9 as a basis for procedures; ii) to study power limits for HAPS ground stations to facilitate sharing with space station receivers; iii) to study the regulatory provisions that might be needed to address the issue of a HAPS deployment in one administration effecting another; iv) other issues relating to sharing with radio astronomy and GSO FSS; Secondly in the bands 27.5 - 28.35 (HAPS to ground) and 31 - 31.3 (ground to HAPS) GHz, where HAPS shall not cause harmful interference to, nor claim protection from stations of other services: v) to conduct studies including sharing with fixed service to identify a suitable and preferably common 300 MHz of the 27.5 - 28.35 GHz; vi) to develop the necessary Recommendations on technical sharing criteria or HAPS system design conditions that are necessary to ensure HAPs can operate successfully on a non-harmful interference, non protected basis; vii) studies of the interference criteria and methodology for evaluating interference between HAPS downlinks and GSO FSS Uplinks; viii) to study the regulatory provisions that might be needed to address the issue of a HAPS deployment in one adminstration effecting another; ix) studies relating to mitigation techniques for HAPS sharing with the fixed service; |
| Agenda 1.9 | This agenda item relates to the 2 500 - 2690 MHz band, which could be used by satellite services including MSS and BSS, including HEO BSS (sound). It calls for studies to review the technical operational and regulatory provisions that would facilitate sharing of these satellite services wit current and future satellite services (for example IMT-2000). Other services with allocations in this band include the fixed service and fixed satellite service. At CPM on 8th July 2003 it was decided not to list the interested Working Parties to avoid duplication of work done within this group. |
| Agenda 1.10 | This agenda item relates to work for the review of the regulatory procedures and associated technical criteria of Appendix 30B, which relates to the allotment plan for GSO FSS systems. It does not cover action on the allotments, the existing systems or the assignments in Appendix 30B. |
| 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 1.12 | This agenda item relates to Plenipot Resolution 86 on "Coordination and notification procedures for satellite networks". It calls upon WRC 2007 to consider proposals to improve the regulatory procedures relating to the introduction of space services in a way that facilitates the rational, efficient, and economic use of radio frequencies and associated orbits including the GSO. |
| 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 1.14 | This agenda item relates to the continued transition to the Global Maritime Distress and Safety System (GMDSS). It covers: i) review of progress towards implementing GMDSS, in particular the continued use of VHF channel 16 and the frequency 2 182 kHz as voice calling channels, taking into account of factors such as decisions by IMO, availability of GMDSS equipped ships, density and classes of ships etc; ii) study into suitable future technology(s) to replace, where considered appropriate, voice calling methods. |
| Agenda 1.15 | This agenda item relates to studies into the possibility of a secondary allocation to the amateur service in the frequency band 135.7 - 137.8 kHz. This band is currently allocated to the maritime mobile, fixed services, and (in Region 3 and certain other countries), Radionavigation. |
| Agenda 1.16 | This agenda item relates to the identification numbers issued to ships and other maritime related stations (eg coastal stations) called Maritime Mobile Service Identities (MMSIs). It covers the: i) review the Recommendations for assigning MMSIs, and identifying alternative resources if there is a rapid exhaustion of free MMSIs ii) study of the implications and any necessary changes involved in assigning MMSIs to SAR aircraft |
| 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) |
| Agenda 1.18 | This agenda item relates to sharing between FSS systems using highly inclined orbits and the fixed service in the 17.7 - 19.7 GHz bands. To facilitate sharing, PFD limits are defined in Article 21, but it has not been determined whether these values are adequate for such non-GSO systems with apogees greater than 18 000 km and orbital inclination between 35 and 135 degrees. It is therefore necessary to study: i) whether the current pfd limits would protect the fixed service, without unduly constraining development of these non-GSO FSS systems; ii) whether there are technical and operational measures that could be implemented in the fixed service to mitigate interference from these satellite systems. |
| Agenda 1.19 | This agenda item relates to spectrum for broadband services via satellite. A number of bands have been identified in 5.BC03 for use by high density fixed satellite service (HDFSS) applications, and it would be beneficial if there were globally harmonised spectrum. Work is therefore required to: i) identify the requirement for spectrum for these types of systems; ii) identify the preferred global harmonised bands, potentially including sharing studies with other services allocated in these bands |
| Agenda 1.20 | This agenda item refers to compatibility between the EESS (passive) service and active services with allocations in adjacent or nearby bands. ITU-R Recommendation SM 1633 undertook a band by band survey of compatibility between passive and active services in adjacent bands. However this Recommendation did not cover all service + band pairs, and so further work is required: i) The Resolution identifies 7 band and service combinations for further study, involving frequencies between 1 400 MHz and 50.4 GHz, and the fixed, mobile, fixed satellite, and radiolocation services. ii) In addition work is required to consider the impact of implementing the values in Rec. 1633 on the fixed service (excluding HAPS) in Regions 2 and 3 in bands around 30 GHz and 50 GHz. |
| Agenda 1.21 | This agenda item refers to compatibility between the radio astronomy service and active space services (such as FSS, BSS, MSS and RNSS) in frequency bands from 150.05 MHz to 22.5 GHz. Resolution 739 [COM 4/15] refers to procedures that could be used during the design of an active space service system or after lauch by which the RAS can enter into consultations with satellite operators to facilitate a mutually acceptable solution to any problem identified. It also notes that studies for some active space services at some bands are incomplete, and therefore that this work should be undertaken to update the table of thresholds in Table 1-1 of Resolution 739 [COM 4/15]. In addition Resolution 740 [COM 4/17] identifies an additional series of bands and services for which further study is required, which could result in updates to existing Recommendations (e.g. SM 1633) or development of new Recommendations, and/or an update to Table 1-1 of Resolution 739 [COM 4/15]. |
| Resolution 4 | This resolution relates to the concept of a period of validity of frequency assignments to space stations, in particular for the geostationary orbit. This would make an assignment discontinued after the expiry of the period of operation, calculated from the date the assignment was brought into service and the satellite network's design period. It calls for studies with respect to its implementation. |
| Resolution 5 | The resolution calls for funds from the UN's Development Programme (UNDP) or other sources to carry out programmes of propagation measurement to assist developing countries, particularly those in tropical areas, plus other work that would assist these countries to be able to plan their systems effectively. |
| Resolution 7 | This resolution refers to the need for fully supported national radio frequency management units to protect national rights and to ensure national obligations are met. It calls for meetings with the BR to design standard organisational structures that could be applied by developing countries. |
| 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 25 | This resolution relates to the Global Mobile Personal Communications by Satellite (GMPCS) Memorandum of Understanding (MoU). It requests administrations to continue to support the implementation of this MoU, and to participate in any ITU-R studies required in the development and revision of relevant Recommendations. |
| Resolution 34 | This resolution relates to the establishment of the broadcast satellite service in Region 3 in the 12.5 and 12.75 GHz band, and sharing with other services in Regions 1, 2, and 3. It identifies the procedures to be used for coordination with space and terrestrial stations, and calls upon studies of sharing between stations in the BSS in Region 3 and space stations of the BSS, FSS, and terrestrial stations in Regions 1 and 2. |
| 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 74 | This resolution covers the need for studies to keep up to date the method in Appendix 7 used in the coordination of earth stations. |
| Resolution 114 | This resolution relates to the band 5 091 - 5 150 MHz, and is the subject of an agenda item for WRC-10. It calls for studies of technical and operational issues relating to sharing in this band between new systems of the aeronautical radionavigation service and the fixed satellite service providing feeder links for non-GSO MSS. |
| Resolution 136 | This resolution relates to frequency sharing between GSO and non-GSO FSS networks in the range 37.5 - 50.2 GHz. It calls for studies of technical, operational, and regulatory studies of sharing arrangements in time for WRC-10 including issues such as avoiding in-line events, diversity, adaptive coding, link balancing, epfd limits, and off-axis eirp limits. |
| Resolution 221 | This resolution covers operation of high altitude platform stations (HAPS) providing IMT-2000 services in bands around 2 GHz. It identifies pfd limits that HAPS stations must meet to protect terrestrial services, plus some gain patterns and out-of-band pfd masks. It invites study within the ITU-R of guidance to facilitate consultation with neighbouring administrations. |
| Resolution 225 | This resolution relates to use of certain frequency bands between 1 525 MHz and 2 690 MHz allocated to the MSS for use by the satellite component of IMT-2000. It calls for sharing studies relating to use of these bands for satellite IMT-2000 and use of the spectrum by other services, such as terrestrial IMT-2000 (in particular around 2 500 - 2 690 MHz) and the radiodetermination-satellite service. |
| 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 525 | This resolution relates to the introduction of broadcast satellite service (sound) systems and complementary terrestrial broadcasting in bands between 1 and 3 GHz. It calls upon studies of the calculation method and interference criteria for sharing between satellite and terrestrial broadcasting stations, and with other effected services. |
| 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 85 [COM4/6] | This resolution relates to verification that non-GSO FSS systems operating in bands for which the equivalent power flux density (EPFD) limits in article 22.2 meet the limits required. ITU-R Recommendation S.1503 to define the algorithm that should be used to verify that such non-GSO FSS systems meets the validation epfd limits. However no software has been validated and supplied to the BR, and so this resolution requests that administrations to develop such software tools. |
| Resolution 89 [COM4/9] | This resolution relates to the backlog in satellite filings, in particular for GSO systems. It identifies a number of areas where the process could be improved, and requests studies into the: i) development of more update to date software for the validation of electronic filings including information on the validation error messages ii) data elements, structure and database for Appendix 4 iii) development of software for the automation checking for compliance with Article 5 |
| Resolution 140 [COM4/13] | This resolution relates to the need to develop protection criteria such as equivalent power flux density (EPFD) to protect GSO downlinks from non-GSO FSS networks operating in the bands 19.7 - 20.2 GHz. |
| Resolution 901 [COM4/19] | This resolution relates to the extension of the coordination arc concept applied in certain bands to those not yet covered. Table 5-1 in Appendix 5 identifies the methods by which it is determined coordination is required, and for some bands it is based upon DT/T and others the difference in longitude of GSO satellites, described as the coordination arc. This resolution calls for further study as to the applicability of the coordination arc to other bands and services not covered by the existing regulations. |
| 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 143 [COM5/6] | This resolution relates to the development of high density applications in the fixed satellite service (HDFSS). A number of frequency bands have been identified in 5.BC03 as potentially suitable, and the Resolution gives guidelines as to ways to implement HDFSS - for example harmonisation of global spectrum. Particular areas that could benefit from further work are: a) development of simplified coordination procedures to facilitate the rapid introduction of HD-FSS terminals; b) study into the potential impact of the deployment of HDFSS in the upper part of the 48.2 - 50.2 GHz band on the satellite passive bands in the adjacent 50.2 - 50.4 GHz band, noting that 5.340 states that these passive services should not impose undue constraints on such services as the HDFSS |
| Resolution 743 [COM5/7] | This resolution relates to the band 42.5 - 43.5 GHz, where power flux density (PFD) limits were introduced to protect the radio astronomy service from emissions from GSO FSS and BSS systems. In article 5.BC05 these are defined as absolute (100% of time) levels, but in this resolution it states that in Region 2 they can be exceeded for not more than 2% of time. However it also calls for studies and development of Recommendations to establish the appropriate balance between this percentage of time and the associated impact on radio astronomy observations. |
| Resolution 609 [COM5/8] | This resolution refers to the protection of aeronautical radionavigation service from radionavigation satellite service networks in the band 1 164 - 1 215 MHz using the equivalent power flux density (EPFD) measure of interference. It identifies an EPFD limit of -121.5 dB(W/m^2) in any 1 MHz never to be exceeded for 100% of time. It calls for software that can be used to calculate this EPFD to allow RNSS systems to be check for compliance by the BR. |
| Resolution 144 [COM5/15] | This resolution refers to the issue of sharing between earth stations of the fixed satellite service (Earth to space) and radiolocation stations in the band 13.75 to 14 GHz. At WRC-03 the dish size limit was reduced from 4.5m to 1.2, but a PFD at country border or coastline has been introduced of -115 dB(W/m^2) in 10 MHz not to be exceeded for more than 1% of time. Further work is required to develop ITU-R Recommendations that will establish technical or operation methods to facilitate sharing - for example allowing more flexible deployment of earth stations and that could be used during bilateral discussions between administrations. |
| Resolution 229 [COM5/16] | This resolution refers to the use of the bands between 5 150 and 5 725 by wireless access networks including radio local area networks. A number of changes in allocations were made in this 5 GHz band during WRC-03, for example additional allocations for the mobile service, and upgrades for other services such as radiolocation. This resolution defines regulations to facilitate use of this band by the various services allocated. It also calls upon further work: i) on the regulatory mechanisms and further mitigation techniques to avoid incompatibilities caused by the aggregate interference from large numbers of WAS devices into non-GSO FSS uplinks in the 5 150 - 5 250 MHz band; ii) on mitigation techniques to protect EESS from stations in the mobile service iii) on test methods and procedures for the implementation of dynamic frequency selection |
| Resolution 610 [COM5/18] | This resolution relates to coordination and bi-lateral resolution of technical compatibility issues for RNSS networks in the bands 1 164 - 1 300 MHz, 1 559 - 1 610, and 5 010 - 5 030 MHz. It identifies when coordination is required and what procedures should be followed. |
| Resolution 146 [COM6/1] | This resolution relates to changes in the C/I criteria to be 27 dB (for single entry) and 23 dB (for aggregate interference) when examining filings under Appendix 30B. It calls for further work on the regulatory procedures and associated technical criteria on Appendix 30B. |
| Resolution 950 [COM7/1] | This resolution relates to bands from 275 to 3,000 GHz, which is currently not covered by the table of allocations. Article 5.565 makes provision for use of these bands by passive services such as radio astronomy, EESS (passive) and space research (passive). There is therefore a need to study potential usage of these bands and possible sharing issues. |
| 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. |
| Resolution 73 | Analysis of compatability problems between BSS in Region 1 and FSS in Region 3 in the frequency bands 12.2 - 12.5 GHz |
| Resolution 75 | Develop the technical basis for determining the coordination area for coordination of RX ES in the space research service with transmitting stations from HD-FS in the 31.8 - 32.3 GHz and 37 - 38 GHz bands. |
| Resolution 76 | Protection of GSO FSS and BSS networks from aggregate EPFD produced by multiple non-GSO FSS systems including: i) methodology for calculating aggregate EPFD ii) accurate modelling of interference from non-GSO into GSO networks; iii) procedures to be used by non-GSO operators when the aggregate EPFD limits are exceeded; iv) measures to identify the interference levels from non-GSO systems in excess of the aggregate limits. |
| Resolution 79 | Study the technical basis of coordination between RA stations operating in the 42.5 - 43.5 GHz band with HD-FS stations |
| Resolution 139 | Study the technical, operational and regulatory aspects of the current and expected future use of FSS allocations for DTH TV broadcasting |
| Resolution 223 | Additional frequency bands for IMT-2000 including: i) sharing of IMT-2000 with other applications and services in the bands 1710 - 1885 MHz and 2500 - 2690 MHz; ii) harmonised frequency arrangements to achieve compatibility with arrangements used for 1G and 2G systems; iii) study future enhancements to IMT-2000 eg for IP services; iv) guidance to meet the needs of developing countries and rural areas |
| Resolution 224 | Study suitable frequency bands for the terrestrial component of IMT-2000 that operates in frequency bands under 1 GHz |
| Resolution 716 | To provide to the BR tools that can be used in the detailed coordination of MSS systems and in the transition of 2 GHz FS links |
| Resolution 731 | To study whether sharing might be possible between active and passive services in bands above 71 GHz. |
| Resolution 732 | Consideration by a future competent WRC on issues dealing with sharing between active servics above 71 GHz. |
