What is W-CDMA?
Wideband Code Division Multiple Access. The wide-band CDMA (W-CDMA) technology promoted by NTT DoCoMo is regarded as one of the most promising candidates for the IMT-2000 radio transmission technology standard. W-CDMA allows data transmission with a quality comparable to that of ISDN. It offers high-speed transmission of video and large-volume data, with high-speed transmission experiments covering video transmission of up to 2Mbps.
