The Universal Telecommunication System (UMTS) and WCDMA are often used as synonyms. The European Telecommunications Standard Institute (ETSI) choose the name UMTS to define the system when positioned in the 2.1 GHz band, which will be the case in Europe and other parts of the world where this frequency is available. In the Americas though, WCDMA will have to use other parts of the frequency band.

UMTS is part of the International Telecommunications Union's IMT-2000 vision of a global family of 3G mobile communication systems. UMTS includes WCDMA radio access technologies together with a core network specification based on the GSM/MAP (Mobile Application Part) standard.
