IMT-2000 (International Mobile Telecommunications-2000) is the global standard for third generation (3G) wireless communications as defined by the International Telecommunication Union.[1][2][3]
In 1999 ITU approved five radio interfaces for IMT-2000 as a part of the ITU-R M.1457 Recommendation.[4] The five standards are:[5]
- IMT-2000 CDMA Direct Spread
- IMT-2000 CDMA Multi-Carrier
- IMT-2000 CDMA TDD
- also known as TD-SCDMA
- IMT-2000 TDMA Single Carrier
- IMT-2000 FDMA/TDMA
- also known as DECT
To meet the IMT-2000 standards, a system must provide peak data rates of at 384 kbit/s for mobile stations and 2 Mbit/s for fixed stations.[2][6][7][8][9]
