Code Division Multiple Access (CDMA)

A digital wireless technology that uses a spread spectrum technique to scatter a radio signal across a wide range of frequencies. CDMA is a 2G technology. WCDMA, a 3G technology, is based on CDMA.

CDMA has multiple variants, including CDMA 1X, cdma2000, CDMA2000 1X, CDMA2000 1xEV-DO and cdmaOne.
