Third generation or 3G networks represent an international standard for wide-area cellular networks that are replacing 2G networks. The main advantage of 3G networks is use of a wider radio spectrum resulting in faster data transmission for advanced multimedia services and a larger network capacity. Carriers can deliver these advantages at a reduced cost compared to 2G network technologies, though physical implementation of a 3G network can be expensive in some cases.
3G networks represent the natural evolution from previous standards. Increasingly Cell phones and handheld mobile devices have incorporated additional services to telephony.
