Radio spectrum for IMT-2000

• In 1992 for IMT-2000 the frequency bands 1885-2025 MHz and 2110-2200 MHz were allocated.

1. Uplink: 1885-2025 MHz (mobile satellite service)

2. Downlink: 2110-2200 MHz (mobile satellite services)

• The terrestrial IMT-2000 networks will work in the following bands:

1. Uplink: 1920-1980 MHz and donwlin: 2110-2170 MHz, FDD with mobile stations transmitting in the lower sub-band.

2. Uplink: 1885-1920 MHz and downlink: 010-2025 MHz, unpaired for TDD operation.

• In europe the TDD band for uplink is from 1885-1900 MHz not available for licenses use of IMt-2000, this is used by cordless telephony (DECT).

Vision:

1. common spectrum worldwide (1.8-2.2 GHz band)

2. Data rates of 9.6 Kbps or higher for global (mega cell), 144 Kbps or higher for vehicular (macro cell), 384 Kbps or higher for pedestrian (micro cell) and up to 2 Mbps for indoor environments (pico cell)

3. Global seamless roamming

4. Multiple environments tat are not only confined to cellular, bu also includes cellular, cordless, satelllite, LANs. wireless local loop (WLL).

5. Enhanced performance and security.

6. Wide range of telecommunications services (voice, data, multimedia, etc)
