从本世纪初3G登上电讯舞台,在历经三年的沉寂后,似乎全球3G通信市场自去年开始回暖,主要表现在以韩日为主的亚太市场出现了增长,虽然欧美市场依然低迷。但无论如何,以数据服务为主的3G通信将是未来移动通信发展的趋势。3G是英文3rd Generation的缩写,指第三代移动通信技术。相对第一代模拟制式手机(1G)和第二代GSM、TDMA等数字手机(2G),第三代手机一般地讲,是指将无线通信与国际互联网等多媒体通信结合的新一代移动通信系统。它能够处理图像、音乐、视频流等多种媒体形式,提供包括网页浏览、电话会议、电子商务等多种信息服务。为了提供这种服务,无线网络必须能够支持不同的数据传输速度,也就是说在室内、室外和行车的环境中能够分别支持至少2Mbps(兆字节/每秒)、384kbps(千字节/每秒)以及144kbps的传输速度。3G业务成长性显著,将成为未来电信运营
From the beginning of this century, 3G boarded the telecommunications arena. After three years of silence, it seems that the global 3G communications market has picked up since last year, mainly due to the growth in the Asia-Pacific market dominated by Korea and Japan, though the markets in Europe and the United States are still in the doldrums. However, in any case, 3G services based on data services will be the future trend of mobile communications. 3G is the abbreviation of English 3rd Generation, refers to the third generation mobile communication technology. Relative to the first generation of analogue cell phones (1G) and the second generation of GSM, TDMA and other digital cell phones (2G), third generation cellphones generally refer to a new generation of mobile communication systems that combine wireless communications with multimedia communications such as the Internet . It can handle images, music, video streaming and other media forms, including web browsing, conference calls, e-commerce and other information services. In order to provide this service, the wireless network must be able to support different data rates, which means that it can support at least 2Mbps (megabytes per second), 384kbps (kilobytes per second) in indoor, outdoor and vehicular environments, respectively Sec) and 144kbps transmission speed. 3G business growth significantly, will become the future telecom operators
