  4. IMT-2000 Frequency Bands The figure shows the current use of the IMT-2000 spectrum identified at ITU WRC-2000. The ITU is preparing globally harmonized frequency arrangements to facilitate IMT-2000 use of all these bands.  1G + 2G 806 960 MHz 2G (Asia & Europe) + 3G 1710 1885 MHz DECT, PHS + 2G + 3G 1885 2025 2110 2200 MHz 2500 2690 MHz

Cell. Cellular Brasil, Venezuela ITU Radio Regulations: 750 MHz of spectrum identified for IMT-2000

  6. Harmonized Introduction of IMT-2000The 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.

  7. 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-03/06Spectrum requirements for future developments of IMT-2000 & beyond systems

  8. 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.
