Cell. IMT 2000 IMT 2000 ITU Radio Regulations: 750 MHz of spectrum identified for IMT-2000

Harmonized Introduction of IMT-2000 The International Regulatory Framework Radio spectrum identification (RR ARTS5): total of 750 MHz (806-960 MHz, 1710-1885 MHz, 1885-2025/ 2110-2200 MHz, 2500-2690 MHz) (RR No.s 5.317A, 5.384A, and 5.388, and Resolutions 212 (Rev.WRC‑97), 223 and 224 (WRC-2000)) ITU RES212 (Rev. WRC-97): “administrations which implement IMT-2000 should make the necessary frequencies available for system development; use those frequencies for IMT-2000; use relevant international technical characteristics, as identified by the Recommendations of the ITU-R and ITU-T.” Licensing and/or initial implementation of IMT-2000: has commenced in many countries within the 806-960 MHz, 1750-1780 MHz, 1840-1870 MHz, 1850-1990 MHz, 1900-1980 MHz, 2010-2025 MHz and 2110-2170 MHz bands.

IMT-2000 Spectrum Harmonization ITU-R WP8F (WG-SPEC) Rec. M. 1036[-2] on frequency arrangements for implementation of IMT-2000 (bands identified at WRC-2000) (3Q2002) ITU Workshop on IMT-2000 Spectrum Implementation (Geneva, 19-20.10.2000) Regulators & industry open discussions on IMT-2000 spectrum issues WRC-03/06 Spectrum requirements for future developments of IMT-2000 & beyond systems

Guidelines for IMT-2000 Spectrum Harmonization Frequency arrangements: Global spectrum/solutions → interoperability Harmonized to the maximum possible → global roaming and economies of scale Flexible → consider existing or planned systems Compatible with pre-IMT-2000 → enable evolution Technology neutral → enable any IMT-2000 technology Support traffic growth, use spectrum efficiently, consider differences between terrestrial & satellite components

B4: enables to optimize spectrum use for paired IMT-2000 operation for countries having implemented B1. B1: can be combined with B2 for countries having implemented B3. ·   B5: implements B2 to harmonize parts of the extension bands globally; enables to maximize spectrum use for paired IMT-2000 operation in countries where B3 is implemented and where the whole band 1 710-1 850 MHz is available. B6: enables to maximize spectrum use for IMT-2000 in countries where B3 is implemented and where the band 1 770-1 850 MHz is not available in the initial phase of deployment of IMT-2000 in this frequency band.
