UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates upto 2 megabits per second (Mbps).
Universal Mobile Telecommunications System (UMTS) is a air interface standard and has evolved since late 1996 under the European Telecommunications Standards Institute (ETSI). European carriers, manufacturers, and government regulators collectively developed the early versions of UMTS as a competitive open air-interface standard for 3G wireless telecommunications.
UMTS offers a consistent set of services to mobile computer and phone users, which is not depend on the location. UMTS is based on the Global System for Mobile (GSM) communication standard. Once UMTS is available, computer and phone users can be continuously connected to the Internet wherever they travel, will have the same set of capabilities. Users will get access to internet via combination of terrestrial wireless and satellite transmissions.
Earlier cellular telephone systems were using circuit-switched connection, where the connections were always dependent on circuit availability. A packet-switched connection uses the Internet Protocol (IP), meaning that a virtual connection is always available.
