无线和宽带,是通信技术的发展方向,中国整个无线市场发展非常迅猛。射频技术在很多领域里,其中包括移动电话、无线局域网,家庭宽带网、数字电视、接收和传输、GPS,都得到广泛的应用。另外,宽带市场现在也在大幅度增长。根据最新的数据统计,中国目前互联网的宽带用户已经超过两千万。所以,目前无线和宽带正在走向融合,而射频技术和宽带技术也成为技术和市场的热点。为进一步跟踪中外信息和通信领域的最新技术和产品,为企业和工程技术人员提供一个高层次面对面进行技术交流的良好机会,2004年10月28日,中电网与中国邮电器材集团公司在中国国际展览中心共同举办了2004中国射频与宽带通信技术研讨会“。在此次研讨会上,来自信息产业部、全球著名半导体器件生产厂家、国内知名通信厂商的领导、专家和工程师们共同探讨了通信技术的行业走向和技术潮流,气氛十分热烈。为了进一步延伸此次研讨会的重大意义和重要价值,我们将此次研讨会所有专家的演讲内容精华做了整理,希望和我们的读者一起分享。
Wireless and broadband, is the development direction of communication technology, the development of China’s entire wireless market is very rapid. Radio frequency technology has been widely used in many fields, including mobile phones, wireless LANs, home broadband networks, digital television, reception and transmission, GPS. In addition, the broadband market is also growing dramatically. According to the latest statistics, China now has more than 20 million broadband users on the Internet. Therefore, at present, wireless and broadband are converging, and radio frequency technology and broadband technology have also become hotspots in technology and market. In order to further keep track of the latest technologies and products in the field of information and communications both at home and abroad, it provides enterprises and engineers with a good opportunity for face-to-face technical exchanges. On October 28, 2004, China Power Grid and China Posts and Telecommunications Equipment Group Corporation Exhibition Center co-organized the 2004 China RF and Broadband Communication Technology Seminar. ”In this seminar, from the Ministry of Information Industry, the world’s leading semiconductor device manufacturers, well-known domestic communications industry leaders, experts and engineers to discuss In order to further extend the great significance and important value of this seminar, we organized the essence of the speech of all the experts in this seminar and hope to share with our readers .
