What is "CDMA"?

CDMA stands for code division multiple access, a form of multiplexing that is based on mathematics rather than time slicing (used by TDMA) or frequency hopping. The term is commonly used to refer to phone networks that make use of this form of multiplexing, such as those run in the United States by Verizon, Sprint, and Alltel. CDMA phone networks make use of 1xRTT, 1xEV-DO, and 1xEV-DV for data transfer. The core CDMA technology was developed by Qualcomm.
