WCDMA is a 3G standard that employs the direct-sequence code division multiple access (DS-CDMA) channel access method and the frequency-division duplexing method to provide high-speed and high-capacity service. 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. These are about technical, you can google it. WCDMA is a trendency.
