CDMA
Code Division Multiple Access (CDMA) technology provides excellent voice capacity and data capability for mobile and fixed wireless networks. Because of its advantages, CDMA serves as the foundation for 3G services worldwide.
CDMA works by converting speech into digital information, which is then transmitted as a radio signal over a wireless network. Using a unique code to distinguish each different call, CDMA enables many more people to share the airwaves at the same time — without static, cross-talk or interference.
