CDMA
Code Division Multiple Access (CDMA) is one of several digital wireless transmission methods in which signals are encoded using a pseudo-random sequence - which corresponds to a different communication channel - that the receiver also knows and can use to decode the received signal. CDMA is one of several "spread spectrum" techniques. CDMA offers improvements over analogue transmission in the areas of reduced call dropping, battery power conservation, more secure transmission and increased service options.
