A 3G wireless cellular technology. This technology is a CDMA upgrade.
CDMA2000 offers a migration path, beginning with CDMA20001X, which is considered by some sources to be a 2.5G technology because it offers maximum sub-3G data rates of 153.6 Kbits per second. During the next few years, users could move to 1xEV-DO (1x evolution, data only) and 1xEV-DV (1x evolution, data and voice), offering data rates up to 614 Kbits per second. Finally, users could move to 3x, which would provide the full 3G maximum throughput of 2.05 Mbits per second.
