W-CDMA
From Wikipedia, the free encyclopedia
W-CDMA is a wideband spread-spectrum mobile air interface that utilizes the direct-sequence spread spectrum method of asynchronous code division multiple access to achieve higher speeds and support more users compared to the implementation of time division multiplexing (TDMA) used by 2G GSM networks.
The term "W-CDMA" is also used to refer to the standard data interface used by the UMTS mobile communication system, W-CDMA (UMTS).
