Code Division Multiple Access (CDMA)

CDMA Phone

CDMA stands for Code Division Multiple Access. It is a technique used for digital communication, and wireless technology in particular, that involve multiplexing. Whereas conventional communication systems use constant frequencies, CDMA uses multiple access, or multiplexing. Multiplexing, in this case accomplished through the specific type known as spread spectrum, uses varied frequencies to transmit audio signals. This, coupled with code division which requires a certain code to send and receive the frequency, further protects CDMA communications from interference.
