摘 要
本文論述了近年來發(fā)展迅速的無線局域網(wǎng)技術(shù)，詳細(xì)闡述了無線局域網(wǎng)的發(fā)展、構(gòu)成、體系標(biāo)準(zhǔn)等。所謂無線局域網(wǎng)（Wireless Local-Area Network，WLAN），即"最后一公里"、"最后一百米"固定─無線接入解決方案。無線局域網(wǎng)是實(shí)現(xiàn)移動(dòng)計(jì)算機(jī)網(wǎng)絡(luò)的關(guān)鍵技術(shù)之一，它是實(shí)現(xiàn)移動(dòng)計(jì)算機(jī)網(wǎng)絡(luò)中移動(dòng)站的物理層與鏈路層功能，為移動(dòng)計(jì)算機(jī)網(wǎng)絡(luò)提供必要的物理接口的網(wǎng)絡(luò)。無線局域網(wǎng)是計(jì)算機(jī)網(wǎng)絡(luò)與無線通信技術(shù)相結(jié)合的產(chǎn)物。從專業(yè)角度講，無線局域網(wǎng)利用無線多址信道的一種有效方法來支持計(jì)算機(jī)之間的通信，并讓通信的移動(dòng)化、個(gè)性化和多媒體應(yīng)用得以實(shí)現(xiàn)。

Abstract
This article discusses the recent rapid development of wireless LAN technology, described in detail the development of wireless local area network, structure, system standards. The so-called wireless local area network (Wireless Local-Area Network, WLAN), that "last mile", the "last 100 meters" ─ fixed wireless access solutions. For mobile wireless local area network is one of the key computer network, it is for mobile computer network in the mobile station physical layer and link layer functions, for the mobile computer network to provide the necessary physical interface network. Wireless LAN is a computer network and wireless communication technology combined with the product. From a professional point of view, wireless local area network using a wireless multiple access channels to support an effective method of communication between computers and mobile technology for communications, personalization and multimedia applications can be achieved.
[Key Words]：WLAN; wireless technology; standards
