universal mobile telecommunications system (UMTS)

Broadband digital wireless transmission of data, voice, video, and multimedia. Based on GSM communication standards, UMTS works at 2 megabits per second (Mbps) and higher speeds over packet-switched networks (used by internet and other digital networks) to provide continuous connection with the internet even while moving about or roaming. In contrast, other wireless systems work over circuit-switched networks and are therefore dependent upon circuit availability.
