Building Wireless Community Networks by Rob Flickenger, just published by O'Reilly & Associates, is available from Amazon.com for US $17.46. According to O'Reilly it answers the first big question those contemplating creating a wireless community network ask: how? "For the cost of hardware and a bit of careful planning, large amounts of information can now be sent for miles at very little cost, without ever involving a telephone or cable company," Flickenger asserts. The book details real-world networking examples, from selecting appropriate equipment and finding likely antenna sites to the general problem of outdoor networking. (One of Flickenger's tips: Lay your antennas in the spring. A well-placed antenna in the winter may disappoint in April when the trees are blooming, which can deflect and drop your signal.) He also includes sample configuration files, network layout diagrams, even topographical maps.
