![]() The cdma2000 family of standards, developed by the Third Generation Partnership Project 2 (3GPP2), was intended to be deployed in several evolutionary phases: ![]() In the above nomenclature, EVDO is short for Evolution – Data Optimized and EVDV, for Evolution – Data and Voice. CDMA2000 1圎V-DO Revision C or Ultra Mobile Broadband (UMB).CDMA2000 1圎V-DO: Release 0, Revision A, Revision B.The name cdma2000 actually denotes a family of standards that represent the successive, evolutionary stages of the underlying technology. Please note that while cdmaOne was a CDMA-based system, GSM is a Time Division Multiple Access (TDMA) system. By contrast, UMTS is also a CDMA-based 3G technology that represents an evolutionary step forward for the 2G GSM networks. It is a third-generation (3G) wireless technology, based on Code Division Multiple Access (CDMA), that has evolved from cdmaOne (or IS95), a 2G technology. ![]()
