Explanation

CDMA (Code Division Multiple Access) is a channel-access technology that lets multiple transmitters share a band by assigning unique codes. It was the basis of several generations of mobile phone networks (notably 2G/3G CDMA systems). It has no connection with X-ray imaging, artificial intelligence, or colour photocopying. Hence it is primarily used in mobile phone communication.
