摘  要

互联网技术发展到现在已经相当成熟,当今互联网已经成为全世界最大最全的信息中心,越来越多的人利用互联网来解放他们的生活,他们利用互联网来完成几乎所有现实生活中的事物。
随着以太网的广泛应用,因特网的日益普及,以及移动终端的不断增加,人们对移动IP接入的需求迅速增长。无线局域网WLAN(Wireless Local Area Network )作为有线以太网的延伸,一定程度上满足了这种需求。
无线局域网采用射频技术构成局域网络,是一种便利的数据传输系统。由于无线局域网设备一般工作于免授权频段,在频段的使用上无需高昂的许可费用,加之WLAN技术的日趋成熟,使得WLAN的应用已经从单纯的有线网络的延伸拓展开来,成为小区尤其是热点地区重要的高速无线数据接入手段之一,应用潜力巨大。同时WLAN的先期部署将促进移动数据业务需求的增长和相关业务应用的成熟。
今天,随着人们对移动办公、高速工作效率的需求,使用无线网络必不可少。 可以预见,凭借无线接入技术本身具有的应用灵活、安装速度快、建设周期短等优势,以及地理应用环境的无限制特性,WLAN必将作为一种高速无线数据接入手段与有线网络一起,构成灵活、高效、完善的宽带网络。

ABSTRACT

The development of Internet technology is quite mature now, today, the Internet has become the world's largest information center for the world, more and more people use the Internet to the liberation of their lives, and they use the Internet to complete almost all of the things in real life.
Along with ethernet widespread application, Internet's daily popularization, as well as mobile termination unceasing increase, the people to move the demand rapid growth which IP turns on. Wireless local area network WLAN (Wireless Local Area Network) took the wired ethernet extending, in the certain degree has met this kind of need.
The wireless local area network uses the radio frequency technology constitution local area network to wind, is one kind of convenient data transmission system. Because the wireless local area network equipment general work to exempts the authorized frequency band, does not need the soaring permission expense in the frequency band use, adds the WLAN technology day by day maturely, caused WLAN the application already to extend from the pure wired network develops, became the plot hot spot area important high speed wireless data to turn on one of in particular methods, the application potential was huge. Simultaneously the WLAN ahead of time deployment will promote the motion data service demand growth and the correlation service application maturity.
Today, as people move office, the demand for high efficiency, the use of WLAN and LAN is essential. Can be expected, with wireless access technology itself is the application of a flexible, quick installation, short construction period, advantages, and application environment of unlimited geographic features, WLAN will as a high-speed wireless data access tools, together with the wired network, constitute a flexible, efficient, improve the broadband network.
