Building Wireless Community Networks

by Rob Flickenger

Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it...

Relevant, accessible, and thin

Building Wireless Community Networks has three attributes I look for in a technology book:- It's relevant- It's accessible- It's thinFor those who are unfamiliar with wireless networking, or those who are relatively new to it, this is a good introduction to the technology. For me, the book did a fine job of relating my knowledge of wired networking to that of wireless, showing how one is an extension of the other. It's a practicle introduction to how microwave technology enables wireless networking, and I found it to be a good primer on microwave communications in general.The book's truer purpose, though, is as an introduction to the community of wi-fi enthusiasts, and to how this medium can (and is) being used to provide data bandwidth to places unheard of just a few years ago.I found the sections on basic, networking configuration (ch. 3, I believe) a bit slow, but still a decent refresher. For someone who has never set up a network before, this section would be more informative. More useful were the sections on wireless tools, microwave antenna and cabling technology (with a wonderful discussion of signal loss that can occur at various points in the connection, and why), and site surveys and topology factors. Also, the discussion on the Pringles can antenna was amusing.This book is for you if:- You want a basic tutorial on wireless networking technology- You have worked with wired networks, but are unfamiliar with RF and microwave communications- You have an interest in setting up your own wireless community network (free or otherwise)This book may not be for you if:- You are looking for an in-depth discussion of the network protocols that are the basis of wi-fi- You enjoy lugging around 500-page technical books that (also) only have about 80 pages or real, useful content.

Building Wireless Community Networks Review

Building Wireless Community ... First Edition, January 2002, 138 pagesBy Rob Flickenger© Copyright 2002 by O'Reilly & Associates, Inc.ISBN 0-596-00204-1Review written March 3, 2002By Donald W. Larson, O'Reilly Book EvangelistEmail: dwlarson@sd.znet.com...Anyone who wants to learn about the usage of WiFi, more commonly known as 802.11b wireless should order this book now and read it immediately upon delivery!Each and every chapter explains is sufficient detail what the new standard is, how to use it and extend the range legally for broadcasts. Anytime someone points out through the purchase of a can of Pringles and then turns that chip container into a radio antenna...to increase the effective range of WiFi, is a signal (pun intended) that value pricing is just a few steps away.Rob demonstrates his mastery of the following topics, the understanding of topological maps, db signal loss over distance, firewalls, NAT, and routing as they pertain to WiFi. For those readers who just want to hook up a wireless 802.11b router and configure their network, this book covers that very well.The book's scope covers the Apple AirPort Base Station and also Linux networks. Also the need for channel separation and bridging of networks for roaming purposes is described.Then there is the section on the types of external antennas and how to build one from the earlier mentioned Pringles can.Obviously, wireless brings a whole new set of questions to the security aspect of wireless networks. Rob explains some techniques that should help and provides urls to other community efforts to help find additional resources and support. See NoCat...as an example of the latter.AppendixThis part of the book includes a section on calculating the loss of signal strength over distances from 0.5 to 20.0 miles! Also provides links to community wireless sites and FCC Part 15 Rules governing the spectrum that 802.11b occupies.IndexComplete and adequate.General Book CommentsIt is my opinion that many neighborhoods could employ the suggested solutions and bypass the big telco's and ISP's to bring unrestricted Internet access to small neighborhood WAN's at a cost lower or equal to what cable and DSL providers offer.Rob has done an excellent job in presenting this new technology. He takes the time to explain technical details in ways easy for the reader to understand.Rating 10 out of 10. This rating is my own personal value system and as such is very subjective. I think a rating of 5 means I would read finish reading a book. A rating of 10 would indicate I had trouble putting a book down and have no complaints at all about it.

Very Practical

I've read two other WLAN books so far, and felt that they were were so technical that they glossed over the need for being practical. This book does a fine job of covering the basics, as well as specific applications. For instance, one section offers step-by-step details on how to configure an Apple AirPort -without- using a Mac. Another section discusses mapping out a network via GPS & topo maps. Other sections cover types of connectors, how to calculate range/distance, and more.My favorite section is the last couple of chapters which include a review of FCC rules as applicable to 802.11b, as well as tidbits on the various Community Network groups located throughout the US...with web links to boot.Definitely worth the $$, IMHO!

Wlans in one night

Excellent. Short and useful. I recommend it to my students as a quick introduction to Wlans. You can read it easily in one night or a weekend. Yet, don't let this claim fool you. Even if concise, the book covers all the essential information to give you a very good understanding of Wlans.

Unbelievable!

I have 23 years in the IT and am learning wireless technology. This is evidently the killer app that everyone is talking about. Before reading this book (which I found accidentally) I did not know about this opportunity. You must already know how wireless works to understand the utmost. You will find that there are many fabulous wireless books for introducing the technology (ex. Jimenez, Rhoton, Bedell). Then you must understand the amazing options and here you will be pleased with this book but you will also want to read about software radios and the new technology for GSM ( Andersson, Ganto, Zakhov).
