As we all know by now, wireless networks offer many advantages over fixed (or wired) networks. Foremost on that list is mobility, since going wireless frees you from the tether of an Ethernet cable at a desk. But that's just the tip of the cable-free iceberg. Wireless networks are also more flexible, faster and easier for you to use, and more affordable to deploy and maintain.The de facto standard for wireless networking is the 802.11 protocol, which includes Wi-Fi (the wireless standard known as 802.11b) and its faster cousin, 802.11g. With easy-to-install 802.11 network hardware available everywhere you turn, the choice seems simple, and many people dive into wireless computing with less thought and planning than they'd give to a wired network. But it's wise to be familiar with both the capabilities and risks associated with the 802.11 protocols. And 802.11 Wireless Networks: The Definitive Guide, 2nd Edition is the perfect place to start.This updated edition covers everything you'll ever need to know about wireless technology.

Using a wireless network is a liberating experience. But underneath the experience lies a complex protocol, and even more complex issues arise when your data isn't limited to traveling on physical wires. How do you structure your network so mobile users can move around effectively? How do you extend wireless coverage so it's available everywhere you need it? What kinds of security issues do wireless networks raise? How do you tune your network for optimal performance? How do you provide enough capacity to support the users you expect initially, and how do you deal with the problems that arise as more users join the network? 802.11 Wireless Networks: The Definitive Guide discusses all these issues, and more. This book is for the serious system or network administrator who is responsible for deploying or maintaining a wireless network. It discusses how the 802.11 protocols work, with a view towards understanding which options are available and troubleshooting problems that arise. It contains an extensive discussion of wireless security issues, including the problems with the WEP standard and a look at the 802.1x security standard.
