摘 要

网络已成为人们学习、生活和办公等不可或缺的一种手段了，这其中局域网占了一定的比重，而无线局域网随着技术的发展，也越来越普及。但是无线局域网与有线局域网之间有什么区别，无线局域网的优势在哪里？两者之间的区别在于所用的介质不同、协议不同。无线局域网的移动性和扩展性是有线局域网所不能比的。

Abstract

The network has become indispensable as a means of people to learn life and office LAN of which accounted for a certain proportion, and wireless LAN technology, more and more popular. What is the difference between wireless LAN and wired LAN, where is the advantage of the wireless LAN? The difference between the two is used in different media, different protocol. Mobility and scalability of the wireless LAN is a wired LAN can not be compared.

Keywords:

The advantages of wired LAN; wireless LAN; difference;Superiority

引 言

移动计算机网络基本上可以分为两种解决方案：广域解决方案和局域解决方案。广域方案主要是依靠无线蜂窝数据通信网络和卫星通信网络作为移动计算的物理网；而在地域范围上受限制，但速率更高的移动解决方案是无线局域网。
