- ITU has allocated 3G Spectrum Allocation 230 MHz frequency for the 3G mobile communication system IMT- 2000: 1885 ~ 2025MHz in the uplink and 2110~ 2200 MHz in the downlink. Of them, the frequency range of 1980 MHz ~ 2010 MHz (uplink) and that of 2170 MHz ~ 2200 MHz (downlink) are used for mobile satellite services. As the uplink and the downlink bands are asymmetrical, the use of dual-frequency FDD mode or the single-frequency TDD mode may be considered.
- This plan was passed in WRC92 for 3G Spectrum Allocation and new additional bands were approved on the basis of the WRC-92 in the WRC2000 conference in the year 2000: 806 MHz ~ 960 MHz, 1710 MHz ~ 1885 MHz and 2500 MHz ~ 2690 MHz.
3G Spectrum Allocation is different in different country but mainly its all having as per below figure.
