What is UMTS?
Universal Mobile Telecommunications Service: The European implementation of the 3G wireless phone system. It is a packet-based transmission of text, digitised voice, video, and multimedia at data rates up to 1,920kbps. UMTS offers a consistent set of services to mobile computer and phone users, no matter where they are located.
UMTS has evolved from its basic format through developments such as High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) to provide very high bandwidth capabilities to support the next generation of telecommunication services. UMTS can be connected to various backbone networks like the Internet, ISDN, GSM or to a UMTS network.
