ITU-R REPORT M.2039-2

Abstract

<strong>Introduction</strong> <br>International Mobile Telecommunications 2000 (IMT-2000) third generation mobile systems started service around the year 2000, and provide access by means of one or more radio links to a wide range of telecommunications services supported by the fixed telecommunication networks (e.g. PSTN/ISDN/ Internet protocol (IP)) and to other services specific to mobile users. Since then, IMT-2000 has been continually enhanced. <br>The Radiocommunication Assembly 2007 adopted Resolution ITU-R 56 that resolves that the term "IMT" be the root name that encompasses both IMT-2000 and IMT-Advanced collectively. <br>The following bands are identified for IMT in the Radio Regulations (RR): <br>Frequency sharing studies and interference analyses involving IMT systems and other systems and services operating in bands identified for IMT may need to be undertaken within ITU-R. To perform the necessary sharing studies between IMT systems and systems in other services, characteristics of the terrestrial component of IMT systems are needed. <br>This Report provides the baseline characteristics of terrestrial IMT-2000 systems only for use in frequency sharing and interference analysis studies involving IMT-2000 systems and between IMT-2000 systems and other systems. <br>Recommendations ITU-R M.1457, ITU-R M.1580 and ITU-R M.1581 provide standardization information relating to IMT-2000 interfaces. <br>Parameters for IMT-Advanced interfaces are not addressed in this Report. <br>The characteristics of the IMT-2000 interfaces have been grouped by frequency bands: <br>&#8211; 450-470 MHz, 698-806 MHz, 790-862 MHz, 880-960 MHz. <br>&#8211; 1 800 MHz, 2 GHz, 2.3 GHz, 2.5 GHz. <br>&#8211; 3 400-3 600 MHz. <br>NOTE 1 &#8211; variations in the parameters may appear depending on the band that is considered, among those listed in a group of frequency bands. Such variations are reflected in the respected tables.
