Universal Mobile Telecommunications System (UMTS) is one of the third generation (3G) cellular technology, which is also being developed in a 4G technology. Currently, the most common uses of UMTS W-CDMA as the underlying air. It is standardized by the 3GPP, and is the European response to the ITU IMT-2000 for 3G cellular radio.
To differentiate UMTS competition between network technologies, UMTS is sometimes marketed as 3GSM, focusing on the combination of the nature of 3G technology and GSM standard which it was designed to succeed.
This article deals with technology, business, usage and other aspects encompassing and surrounding UMTS, the 3G successor to GSM, which uses the W-CDMA air interface and GSM infrastructure. All issues strictly related to the W-CDMA May interface itself be better described in the W-CDMA.
