CDMA2000 - definition


A 3G wireless technology, evolved from cdmaOne. Improvements over the old standard include faster data rates, always-on data service, and improved voice network capacity.

There are three types of CMDA2000:

  • 1xRTT doubles the capacity of cdmaOne and supports up to 144 kbps data speeds
  • 1xEV-DO supports data rates up to 2.4 Mbps but needs to be deployed in a separate spectrum. This standard doesn't support voice calls and needs to be combined with 1xRTT.
  • 1xEV-DV supports data rates of around 3-5 Mbps and voice capabilities
