摘要

针对无线局域网性能和速度等方面的不足

讨论采用智能天线技术改善无线局域网的性能.重点介绍波束切换系统、自适应阵列天线系统以及基于收、发分集的多输入多输出系统在无线局域网中的应用

给出了不同系统的结构及关键技术.最后介绍了一种实用的应用于IEEE802.11b标准的波束切换系统.

Abstract

The article provides an overview of Smart Antenna technology in wireless LAN systems.Since Smart Antenna technology has powerful spatial processing ability

it is regarded as a promising solution to enhancing the data rates and capacity of wireless LAN systems.This article discusses the switched beam based

the adaptive array based and Multiple-Input-Multiple-Output based wireless LAN systems and their relevant key technologies.A set of small size

practical switched beam antenna system

well suited for IEEE 802.11b Standard

is designed and tested.The antenna system has 9dB gain and can be applied to the wireless Access Point.Based on the testing results

an improved scheme is also proposed

with all the beams cophasal excited.
