1、Rep. ITU-R M.2024 REPORT ITU-R M.2024 SUMMARY OF SPECTRUM USAGE SURVEY RESULTS 1 Introduction 1 (2000) A number of administrations have indicated their current and planned spectrum usage of the bands which are considered potentially suitable for IMT-2000 as summarized in this Report. This was origin
2、ally in response to BR Circular Letter 8/LCCE/54, 11 February 1998 and other ITU-R contributions. Such information complements the ITU-R contribution on Chapter 1.1 of the CPM Report to WRC-2000. Additionally, several administrations are assessing their long-term spectrum requirements for IMT-2000 a
3、nd have participated in the ITU-R efforts to make that determination. A further step in the process, taking into account additional spectrum requirements is the study of candidate bands which may be suitable for any additional IMT-2000 requirements. The selection process for candidate bands must inc
4、lude consideration of compatibility, coordination and sharing with other primary services. To aid this process, the ITU-R has developed an estimate of the additional spectrum requirement for IMT-2000, the results of which are included in the CPM Report to WRC-2000. Administrations should continue to
5、 identifl possible world-wide spectrum for IMT-2000, noting the principles listed below: - - World-wide common fiequency bands should be considered as the first choice to enable universal access. Recommendation ITU-R M.687 recommends the spectrum range suitable to be considered for any additional sp
6、ectrum for IMT-2000. Sharing issues and regulatory constraints should be analyzed for bands currently in use by other services. Preference should be given to options that permit contiguous spectrum. - - This Report provides useful information for administrations when considering IMT-2000 spectrum re
7、quirements in preparation for WRC-2000. 2 Summary IMT-2000 defines third generation mobile systems which are scheduled to start service around the year 2000 subject to market considerations. They will provide access, by means of one or more radio links, to a wide range of telecommunication services
8、supported by the fixed telecommunication networks such as public switched telecom- munications networks (PSTN) and integrated services digital networks (ISDN), and to other services which are specific to mobile users. A range of mobile terminal types is encompassed, linking to terrestrial and/or sat
9、ellite based networks; these terminals may be designed for mobile or fixed use. Key features of IMT-2000 are: - - - high quality; - - worldwide roaming capability; - high degree of commonality of design worldwide; compatibility of services within IMT-2000 and with the fixed networks; small terminals
10、 for worldwide use; capability for multimedia applications and a wide range of services and terminals. The subject matter of IMT-2000 is complex and its representation in the form of Recommendations and Reports is evolving. To maintain the pace of progress on the subject, it is necessary to produce
11、a sequence of Recommendations and Reports on a variety of aspects. The Recommendations and Reports strive to avoid apparent conflicts between themselves. Future Recommendations and Reports, or revisions, will be used to resolve any discrepancies. COPYRIGHT International Telecommunications Union/ITU
12、RadiocommunicationsLicensed by Information Handling ServicesRep. ITU-R M.2024 Background Administrations may consider the following factors that are relevant to the IMT-2000 spectrum: that IMT-2000 systems are defined by a set of interdependent ITU Recommendations and Reports of which this Report is
13、 a part thereof; that RR No. S5.388 indicates that “the bands 1 885-2 025 MHz and 2 110-2 200 MHz are intended for use, on a world-wide basis, by administrations wishing to implement International Mobile Telecommunications-2000 (IMT-2000). Such use does not preclude the use of these bands by other s
14、ervices to which they are allocated. The bands should be made available for IMT-2000 in accordance with Resolution 212 (Rev.WRC-97)”; that the RR also allocate within these bands the portions 1 980-2010 MHz and 2 170-2200 MHz to the MSS on a worldwide basis, potentially for use by the satellite comp
15、onent of IMT-2000, under the provisions of RR No. S5.389A; that the RR also allocate the bands 2 010-2 025 MHz and 2 160-2 170 MHz in Region 2 to the MSS under the provisions of RR Nos. S5.389C, S5.389D and S5.389E; that portions of the bands identified for the implementation of IMT-2000 are used by
16、 existing terrestrial FSs under current allocations; that the initial implementations of IMT-2000 are expected to commence around the year 2000 subject to market considerations; that IMT-2000 systems will provide different categories of services in various environments; that the bands identified in
17、b) above are shared with other systems of the MS, FS and MSS and the band 2 110- 2 120 MHz is shared with the space research service, and that many of these systems are in current use; that these bands are used differently in various countries; even within the same Region; that the traffic and servi
18、ce mix carried by IMT-2000 systems may vary fiom country to country, and also within countries; in some parts of the world, additional spectrum may be required whilst in other parts of the world the fiequency bands identified in b), c), and d) above could be adequate to meet IMT-2000 services presen
19、t and future demands; that the amount of traffic handled by mobile systems as well as the number and diversity of services will continue to grow; that there is a need to support the operation of IMT-2000 terminals in different regulatory environments; that use of a worldwide fiequency bands will fac
20、ilitate the global roaming of terrestrial and satellite components; that future systems may include the use of a range of cell types fiom small indoor cells to large satellite cells in a given location; Administrations may further consider, relative to the terrestrial component: that Report ITU-R M.
21、2023 concludes that there is a need for 160 MHz of additional spectrum for terrestrial IMT-2000, beyond the terrestrial IMT-2000 spectrum already identified in RR No. S5.388 and beyond the spectrum used in the various Regions for first and second generation mobile systems; that administrations may c
22、hoose to permit operators to use fiequency bands currently allocated to pre-IMT-2000 mobile service for IMT-2000 usage as a strategy for the evolution fiom second to third generation mobile systems having IMT-2000 capabilities; that spectrum requirements for the terrestrial component of IMT-2000 wer
23、e estimated in Report ITU-R M. 1 153 prior to WARC-92 at which time the primary service emphasis was on voice services, whereas IMT-2000 systems will provide a variety of wideband data and multimedia services in addition to voice services; d) that harmonized worldwide use of fiequency bands will fac
24、ilitate global roaming; COPYRIGHT International Telecommunications Union/ITU RadiocommunicationsLicensed by Information Handling ServicesRep. ITU-R M.2024 3 3.3 Administrations may further consider, relative to the satellite component: a) that Report ITU-R M.2023 concludes that the total satellite s
25、pectrum requirement for the years 2005 and 2010 is 2 x 31.5 MHz and 2 x 67 MHz respectively; b) that the need for additional spectrum for the MSS in the 1 to 3 GHz range has been stated in the CPM Reports to the last two WRCs. The CPM Report to WRC-95 indicated that a total allocation of between 2 x
26、 75 MHz and 2 x 150 MHz would be required by 2005 (Chapter 2, part A.2, 3) and the CPM Report to WRC-97 indicated that 2 x 250 MHz would be necessary by 2010; c) that currently the RR allocate about 2 x 1 15 MHz to the MSS in the 1-3 GHz range, with some Regional variations; d) that most of these ba
27、nds are used by other services in most countries, substantially reducing the actual availability of those bands for the MSS, and in many countries they are not available for MSS at all. 4 Survey responses Annex 1 provides the responses to the survey on spectrum utilization.

At present parts of the band are also used for other services (e.g. tactical radio relay links) and demand for these services are likely to continue. CEPT is investigating
30、whether this band may be considered as a candidate band for IMT-2000 expansion 470-806 MHz - TV broadcast band and land mobile use. With transition from analogue to digital TV, 24 MHz (764-776/794-806 MHz) has been re-allocated for FS and MS for public safety use. This spectrum would not be suitable
31、 for IMT-2000. 36 MHz (746-764/776-794 MHz) has been re-allocated for FS, MS and broadcast service (BS) for commercial use. Transition to digital TV scheduled to be substantially complete by December 3 1,2006, an additional 48 MHz of spectrum (698-746 MHz) will be recovered in the long term. Specifi
