I thought this book would get me up to date on most of the latest thinking with regards to Wireless LAN's and Communities. Perhaps it has, but there's nothing much to say.
This book is unbelievably thin compared to the concise, info-full tomes normally produced by Orielly. A pleasure if we're dealing with something concise and powerful - but we're not. A significant amount of the "144 pages" come across as padding rather than content. I'd estimate only around half of it is "meat" with a lot of repeated, waffly information which I do not expect from Oreilly books - though this may be classed as "easy to read" (which it is - fair play).
Much of the book covers configuration of a limited number of devices (one?) - such as the Apple Airport, which surely you can get from any WLAN device manual. A good comparison of pros/cons of different devices, approaches, software and technologies may have been interesting. Especially rather than just mentioning a couple and largely recommending other Oreilly books to read instead.
The author's main credentials seem to be setting up a wireless LAN with a limited range of technology for Oreilly and then setting up a point-to-point connection from the Office to his home. Admittedly the Pringles can is a bit of innovative fun, but probably not much more. The U.S. TOPO (topographical) Maps info is interesting, but not so relevant in the UK.
Having just bought and starting to read Orielly's Wireless LAN's Definitive Guide, I think I've learned more in the first few, concise pages than almost the whole of this book.
