摘 要
本文论述了近年来发展迅速的无线局域网技术，详细阐述了无线局域网的发展、构成、体系标准等。所谓无线局域网（Wireless Local-Area Network，WLAN），即"最后一公里"、"最后一百米"固定─无线接入解决方案。无线局域网是实现移动计算机网络的关键技术之一，它是实现移动计算机网络中移动站的物理层与链路层功能，为移动计算机网络提供必要的物理接口的网络。无线局域网是计算机网络与无线通信技术相结合的产物。从专业角度讲，无线局域网利用无线多址信道的一种有效方法来支持计算机之间的通信，并让通信的移动化、个性化和多媒体应用得以实现。
关 键 词：WLAN ；无线技术 ； 标准
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.
