  CDMA2000 Definition: TechEncyclopedia from TechWeb
In 2000, CDMA2000 was the first 3G technology to be commercially deployed as part of the ITU's IMT-2000 framework (see IMT-2000).
The first version of CDMA2000 provides data rates of 307 Kbps (downlink) and 153 Kbps (uplink) as well as twice the voice capacity on a single 1.25MHz CMDA channel in new or existing spectrum.
CDMA2000 3X is also known as "3XRTT," "MC-3X," and "IMT-CDMA MultiCarrier 3X." See CDMA, WCDMA and cellular generations.

 cdma2000 specification and information page
Cdma2000 specification was developed by the Third Generation Partnership Project 2 (3GPP2), a partnership consisting of five telecommunications standards bodies: ARIB and TTC in Japan, CWTS in China, TTA in Korea and TIA in North America.
Cdma2000 is not constrained to only the IMT-2000 band, but operators can also overlay acdma2000 1x system, which supports 144 kbps now and data rates up to 307 kbps in the future, on top of their existing cdmaOne network.
Cdma2000 1x with lower data speed is considered to be a 2.5G technology.

CDMA2000 1X is the basic 3G standard, in fact some people only consider it a 2.75G system, and it is being developed beyond this.
In what is termed CDMA2000 1xEv, there are further developments to bring it in line with the UMTS or Wideband CDMA system that is being deployed in Western Europe and many other areas.
CDMA2000 is a well established 3G technology, and it is particularly successful in the USA, and Asia Pacific regions as well as having a significant presence in many other parts of the world.

 cdma2000 Explained
While the cdma2000 specification allows for an evolutionary migration to later advances in cdma2000 that use core IP networks and voice-over-IP, the current 1X migration requires relatively modest hardware and software upgrades to existing cdmaOne infrastructure.
cdma2000 can be deployed in existing spectrums such as 1900MHz along with an existing cdmaOne system, overlaying its new feature set and increased capacity on the existing cdmaOne networks.
Handsets using cdma2000 technology will also be backward compatible to the existing cdmaOne networks, so current handsets and features will operate over next generation networks providing continued access both at home and while roaming.
