CDMA2000

Often also called WCDMA, CDMA2000 is synonymous with 3G pertaining to wireless networks. 1x is the first phase of implementation of a 3G CDMA based cellular network and offers about twice the capacity of current exsisting 2G networks, with data transfer rates of 144Kbps. CDMA2000 1x is backwards compatible with exsisting CDMA networks, and sends and receives data in packets. It allows the data channel to be allocated to other users if there is no data being transmitted, and therefore makes the network more efficient.
