Universal Mobile Telecommunications System (UMTS)
Universal Mobile Telecommunications
System (UMTS) is one of the third-generation (3G) cell phone
technologies. Currently, the most common form uses W-CDMA as the
underlying air interface, is standardized by the 3GPP, and is the
European answer to the ITU IMT-2000 requirements for 3G cellular
radio systems.
To differentiate UMTS from competing network technologies, UMTS is
sometimes marketed as 3GSM, emphasizing the combination of the 3G
nature of the technology and the GSM standard which it was designed
to succeed.
