3G or third generation also called UMTS (Universal Mobile Telecommunications Systems) is the generic term used for the next generation of mobile communications systems.

3G builds upon the increased capacity GPRS offers but is an upgraded technology. These new systems will provide enhanced services to those available today i.e. voice, text and data but will also delivery major changes in the way that mobile phones and PDA type devices can work with real-time applications. In much the same way that Broadband internet access has changed the way businesses are able to work over the Internet.
