CDMA (See our CDMA section)

The new 3G services are almost all flavours of technolgies based on the generic name, CDMA (Code Division Multiple Access). CDMA is a digital wireless technology that allows multiple users to share radio frequencies at the same time without interfering with each other. A telephone or data call is assigned a unique code that distinguishes it from others and and since the signals hop among different frequencies.
Current 2G services using the original CDMA "IS-95" technology are know as cdmaOne. 3G services will use new high-speed versions of CDMA called W-CDMA, or its competing technology, cdma2000. (More on CDMA)
