UMTS is the 3G wireless standard that provides data transfer rates greater than 2Mbps. It combines the GSM network infrastructure with CDMA air interface technology. UMTS uses W-CDMA technology and offers download speeds of 11Mbps theoretically, though most users experience around 384Kbps. It requires new network equipment and frequencies compared to 2G networks. In the US, Cingular and T-Mobile have begun limited UMTS deployments, but coverage remains poor overall. Potential applications include video telephony, media downloads, and television on mobile phones, but network and device limitations have prevented widespread adoption.
