It can handle various media forms such as image, music, video, etc., and provide various information services including web browsing, teleconference and e-commerce. In order to provide the services, the wireless network must be able to support different data transmission speed, that is to say, in indoor, outdoor, and traffic environment can support at least 2 MBPS respectively (megabit per second), 384 KBPS (thousands of bits) per second and transfer rate of 144 KBPS. Have strong function is the basis of third-generation (3 g) mobile phone extremely high speed of data transmission, GSM mobile communication network of transmission speed of 9.6 KB per second, and third generation of mobile phones could eventually reach the speed of data transmission will be up to 2 MB per second. For this reason, the Internet technology is fully combined into the 3G mobile phone system, and the most important one is the data packaging technology. GPRS, which USES data packaging technology on GSM, has reached a speed of 384kbps per second, which is twice the speed of d-isdn. 3G mobile phones support high-quality voice, packet data, multimedia business and multi-user rate communication, which will greatly expand the content of mobile phone communication
