3G/WCDMA

What is 3G/WCDMA?

Developed by the global GSM community to support third-generation (3G) mobile services, WCDMA is the designated air interface for one of the International Telecommunications Union’s (ITU’s) family of 3G mobile communications systems. WCDMA is used in the radio leg of both UMTS and HSPA networks.

As well as supporting conventional voice, text and MMS services, WCDMA (Wideband Code Division Multiple Access) can carry data at high speeds, enabling mobile operators to deliver richer mobile multimedia services such as music-on-demand, TV and video streaming and broadband Internet access.
