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."
