What is 3g Wcdma?

3G UMTS capabilities UMTS uses Wideband CDMA - WCDMA - as the radio transmission standard. It employs a 5 MHz channel bandwidth. Using this bandwidth it has the capacity to carry over 100 simultaneous voice calls, or it is able to carry data at speeds up to 2 Mbps in its original format.

Simply so, is Wcdma same as 4g?

The question is not correct. WCDMA is “a way of sending information in air (Radio Access Technology)” while 4G or 3G “a system t of mobile telecommunication”. In general, 3G system uses WCDMA 'Radio Access Technology' while 4G uses 'OFDMA' Radio Access Technology. For same thing, 2G uses GERAN Radio Access Technology.
