Harmonized Introduction of IMT-2000 The International Regulatory Framework • Radio spectrum identification (RR ARTS 5): total of 750 MHz (806 -960 MHz, 1710 -1885 MHz, 1885 -2025/ 2110 -2200 MHz, 2500 -2690 MHz) (RR No. s 5. 317 A, 5. 384 A, and 5. 388, and Resolutions 212 (Rev. WRC‑ 97), 223 and 224 (WRC-2000)) • ITU RES 212 (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 WP 8 F (WG-SPEC) Rec. M. 1036[-2] on frequency arrangements for implementation of IMT-2000 (bands identified at WRC-2000) (3 Q 2002) • 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

B 4: enables to optimize spectrum use for paired IMT-2000 operation for countries having implemented B 1: can be combined with B 2 for countries having implemented B 3. · B 5: implements B 2 to harmonize parts of the extension bands globally; enables to maximize spectrum use for paired IMT-2000 operation in countries where B 3 is implemented and where the whole band 1 710 -1 850 MHz is available. B 6: enables to maximize spectrum use for IMT-2000 in countries where B 3 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.
