What is "WCDMA"?

WCDMA stands for Wideband Code Division Multiple Access, and is the 3G technology, as defined by the ITU's IMT-2000 spec, that is used by UMTS and NTT DoCoMo's FOMA network. WCDMA makes use of many core CDMA technologies created by Qualcomm, though not nearly as many as do regular CDMA carrier networks. WCDMA networks and devices are not compatible with regular CDMA networks and devices, they merely share some of the same core technologies.
