摘    要:WLAN的出现,充分解决了有线网络先天性缺陷所带来的一系列问题。与有线网络相比,WLAN具备了很多特定优势。作为有线局域网的一种补充和扩展,WALN使计算机具有了可移动性,能快速、方便地解决有线网络不易实现的网络连通问题,成为今后网络发展的主导方向。IEEE802.11标准是IEEE制定的无线局域网标准,各厂商的产品在同一物理层上可以互相操作,这样就使得无线局域网的两种主要用途“多点接入”和“多网段互联”更易于低成本实现,从而为无线局域网的进一步普及打通了道路,文中介绍了几个常用标准的特点。

关 键 词:无线局域网  IEEE802.11无线局域网协议

Abstract:The appearance of WLAN fully solves a serious of problems bought by the congenital defects of the wire network.Compared with the wire network,WLAN is equiped with many specified advantages.As the supplement and extension of the wire local area network,WLAN makes the computers movable.It can fast and conveniently solve the problem of network connection which is not easy for the wire network to realize,so it becomes the dominant direction of the network development in the future.The standard of IEEE 802.11 is the wireless local area network standard worked out by IEEE.The products of various manufacturers can be operated together on the same physical layer.Thus,it makes the two main functions of the wireless local area network,"connection of multiple points" and "internetworking of multiple net segments",easier to be realized with low costs.Thereby,the road for the further popularization of the wireless local area network is got through.This article briefly introduces the features of several standards in common use.
Keywords:wireless local area network(WLAN)  IEEE 802  1 WLAN protocol
