CDMA

(Code Division Multiple Access) A protocol for wireless data and voice communication, CMDA is widely used in cellphone networks, but also in many other data communications systems. CDMA uses a technique called “Spread Spectrum” whereby the data being transmitted is spread across multiple radio frequencies, making more efficent use of available radio spectrum. There are a number of additional protocols built on top of CDMA, such as 1xRTT (also called CMDA2000).
