Overview CDMA2000

CDMA2000 is a wireless platform that is part of the IMT-2000 specification
and is an extension of the CDMAOne wireless platforms using the IS-95A/B
and J-STD-008 standards. CDMA2000, being a IMT-2000 standard, is
geared toward the transport and treatment of 3G wireless services supporting
multimedia applications for fixed as well as mobile situations.
In the existing 2G platforms that are operational today for both cellular
and PCS, the same radio bandwidth is allocated for voice and data. The
data services are, of course, really circuit-switched services, without the
capability to overbook the data service and thus increase the capacity of a
wireless system through the appropriate use of data services.
