In july 1998, the ieee standardization group selected the ofdm modulation technique for their new ieee802. 1l a standard, targeting data transmission from 11 up to 54 mbps. meanwhile, this new ieee standard is the first one to use ofdm in packet based communications. ( before the proposal of this standard, use of ofdm was limited to continuous systems ) in this paper, the author firstly presents the technical characteristics and the typical application of wireless local area network ( wlan ), analyzes its topology structure, the network configuration and etc. then the author illustrates the media access control and the operation and frame structure of physical layer
1998年7月， ofdm技術正式被ieee標準組確定為ieee802 . 11a物理層調制方法，使得無線局域網數據傳輸速率由11mbps提高到54mbps ，性能得到明顯改善。同時該標準是第一個將ofdm技術應用於包傳輸通信中的ieee標準（在該標準提出以前， ofdm的使用通常局限於連續傳輸系統中） 。本文中，作者首先介紹了無線局域網的技術特點和典型應用，分析了其拓撲結構、網路配置功能等。
