CDMA is used as the access method in many mobile phone standards such as cdmaOne, CDMA2000 (the 3G evolution of cdmaOne), and WCDMA (the 3G standard used by GSM carriers), which are often referred to as simply CDMA.
ANSI-41 is the standard now approved for use as the network-side companion to the wireless-side AMPS (analog), IS-136 (Digital AMPS), cdmaOne, and CDMA2000 networks.
