今年的上海国际通信展已经落下帷幕，展会上，各个通信厂商，都使出浑身解数，向观众展示自己公司的最新技术和产品。第２．５代无线移动通信ＧＰＲＳ（通用分组无线业务）产品是各大公司和观众共同关注的焦点。 随着第三代移动通信标准的出台和用户对移动多媒体业务的需求的急剧增长，现有的ＧＳＭ网络将不可避免地向Ｗ－ＣＤＭＡ（宽带码分多址）演变，这种演进的过程据估计大约需要２－３年。但这并不意味着移动运营商们只能等待，通过采用ＧＰＲＳ技术，可使现有ＧＳＭ网络轻易地实现与高速数据分组的简便接入，ＧＰＲＳ将是通向３Ｇ的一个重要里程碑。 This year’s Shanghai International Telecommunications Exhibition has come to an end, the show, all communications companies, have resorted to every means to show their own company’s latest technology and products. The 2.5 generation of wireless mobile communication GPRS (General Packet Radio Services) products are the focus of attention of major companies and viewers. With the promulgation of the third generation mobile communication standard and the rapid increase of users’ demand for mobile multimedia services, the existing GSM network will inevitably evolve to W-CDMA (Wideband Code Division Multiple Access). The evolution of this process Estimated to take about 2-3 years. However, this does not mean that mobile operators can only wait and can easily make existing GSM networks easy to access with high-speed data packets by adopting GPRS technology. GPRS will be an important milestone toward 3G.
