Deploying wireless local area networks (WLANs) based on IEEE 802.11 radio standards can be deceptively simple. Home users plug wireless routers into broadband links and start using them without further set-up. But, as we shall see, implementing a successful business-grade WLAN requires considerably more forethought and planning.This paper explains the differences between 802.11 radio standards, wireless security features, and how to design WLANs that can meet your needs for reach and performance. It explains how devices can be laid out and fine-tuned to optimize coverage and avoid sources of interference. The aspects of wireless security are discussed to highlight the differences in authentication, data encryption, and packet integrity technology which may affect the wireless technology selected. Finally, this paper describes how to perform a successful site survey, and includes links to free and commercial tools that can help you complete that task. If designed and implemented properly, wireless networks will provide many benefits and enhance user productivity.
