What is CDMA?

CDMA (Code Division Multiple Access) is a channel access method used by various radio communication technologies. CDMA employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code) to allow multiple users to be multiplexed over the same physical channel. It is commonly used in mobile phone networks, particularly in 2G and 3G systems, as well as in satellite communication.
