What is IMT-2000
Geneva, 2001-2002
IMT-2000 is 3G
3G is a term coined by the global cellular community to
indicate the next generation of mobile service capabilities,
e.g., higher capacity and enhanced network functionalities,
which allow advanced services and applications, including
multimedia.
IMT-2000 (International Mobile Telecommunications2000) is the ITU globally coordinated definition of 3G
covering key issues such as frequency spectrum use and
technical standards .
Multiple radio technology options have been included in the IMT-2000
standard to allow seamless service evolution from the various 2G
mobile standards that are extensively deployed around the world.

IMT-2000 is much more
IMT-2000 systems are expected to provide support for :
- high transmission data rates for indoor and outdoor operations
- symmetrical and asymmetrical data transmission
- circuit-switched and packet-switched services, such as Internet
Protocol (IP) traffic and real-time video
- voice quality comparable to wire-line quality
- greater capacity and improved spectrum efficiency
- several simultaneous services to end-users and terminals, for
multimedia services
- global, i.e. international, roaming between different operational
environments
- economies of scale through open global standards to meet the
needs of the mass market.

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 IMT2000 use
of all these bands.

It is the ITU goal that in IMT-2000 all radio access options should work
with all network options, e.g., including cdma2000 on GSM MAP and
W-CDMA on IS-41.
