Product Description
Amazon.co.uk Review
802.11 Wireless Networks: The Definitive Guide aims to codify the body of knowledge needed to design and maintain wireless local area networks (LANs). Among network designers and administrators, wired Ethernet is a known quantity. Plenty is known about how to build good twisted-pair network infrastructures, how to keep them secure, and how to monitor their excess capacity. Not so for the wireless Ethernet networks (built around the IEEE 802.11x standards)--these hold much more mystery for even experienced network designers. The authors succeed admirably in this, covering what installation and administration teams need to know and digging into information of use to driver writers and others working at lower levels.
The only significant detail that's been excluded has to do with security--a notorious weak point of 802.11x LANs. The authors cover the feeble-but-widely-used Wired Equivalent Privacy (WEP) authentication protocol in detail, and devote another whole chapter to 802.1x, which is an emerging authentication scheme based on Extensible Authentication Protocol (EAP). The author has considerable skill in communicating information graphically, and does a great job of using graphs to show how communications frequencies shift over time and how conversations among access points and network nodes progress over time. This is indeed an authoritative document. --David Wall
Topics covered: How IEEE 802.11a and 802.11b wireless networks (also known as WiFi networks) work, and how to configure your own. The framing specification is covered well, as are authentication protocols and (in detail) the physical phenomena that affect IEEE 802.11x radio transmissions. There's advice on how to design a wireless network topology, and how to go about network traffic analysis and performance improvement. --This text refers to an alternate Paperback edition.
Review
'Building Wireless Community Networks is an enthusiastic introductory guide to a technology which can really be put to use to change people's lives. Wireless gives the power of the network back to the people, and this book helps to demystify the technology and enable any community to take control.' Linux User, March/April (Classic Title)

This book was just what I was looking for, an in depth, technical workthrough of setting up a wireless network with off the shelf tools. Theres actually more than I was looking for; as it discusses the 802.11b protocol, and even includes specs for the SNMP MIB's, which while you can them get off the internet easily enough, means that its a one stop shop for the wireless network setup kit. Its the no nonsense, not assuming youre an idiot, or completely savvy with the subject style that OReily are famous for. While I think some of thier books have failed to live up to thier otherwise superb standard, this one does not, and Gast has done a good job. I would, having said that, have liked more on the security angle - HOW to secure the wireless network a little more. He mentions VPN's and IPSec, and goes into a lot of detail on WEP (including exactly why its insecure), but he doesnt give any concrete examples. Given that a lot of Oreilly's other books are on security, firewalls etc, thats understandable, but i felt it would have rounded off an otherwise impressively comprehensive guide.

Product arrived in a good packaging and I have already started to read it. It is very very useful for the purpose that has been purchased.

This is a first rate book from O'Reilly. Plenty of depth, to the point that there will be little need to buy any other book on the subject. Here you will learn all about the physical layer, the 802.11 protocol, and plenty of information on the alphabet soup that surrounds it.
The guide is readable and logically laid out. It will make a great reference work but can be read through as a single whole too.
