CDMA stands for code division multiple acces. It started as a militar project but Qualcomm iniciated a standard for digital mobile telephony known as IS-95 or CDMAone (IS-95 and GSM are the mayor players on celular deployment today for 2G telephony). For 3G evolution UMTS/WCDMA (wideband CDMA) and CDMA2000 where proposed by 3GPP/2 and Qualcomm respectively. WCDMA is claimed to be the GSM evolution (migrating from TMDA tech. to CDMA tech.) and CDMA2000 as the evolution of CDMAone.
