随着社会经济与网络技术的日益发展,传统的有线网络已不能满足社会发展需求,因此便捷灵活的无线网络产生了,并逐渐走向成熟。本文介绍了无线局域网的分类、特点和应用场合,并通过在三门峡实验中学教学楼2层-4层架设无线局域网,对无线局域网进行安装测试,最后对测试数据进行分析,得出无线局域网是有线网络的有效补充的结论。 With the development of social economy and network technology, the traditional wired network has been unable to meet the needs of social development. Therefore, a convenient and flexible wireless network has emerged and gradually matured. This article introduces the classification, characteristics and applications of wireless LAN, and set up wireless local area network in the second floor -4 storeys of Sanmenxia Experimental Middle School to install and test the wireless LAN. Finally, the test data analysis shows that the wireless LAN is wired The conclusion of the network is an effective supplement.
