W-CDMA stands for Wideband Code Division Multiple Access
Its an air interface standard found in 3G mobile telecommunications networks designed for “always-on” packet-based wireless service, so that computers entertainment devices and telephones may all share the same wireless network and be connected to the internet, anytime anywhere.
It was adopted as a standard by the ITU under the name "IMT-2000 direct spread."
It is the technology used in the Universal Mobile Telecommunications System (UMTS) and is also known as UMTS-FDD.
It utilizes the DS-CDMA channel access method and the FDD duplexing method to achieve higher speeds and support more users compared to most time division multiple access (TDMA) schemes used today.
