The need for wireless connectivity is increasing. This is especially true in developing countries that are lacking in infrastructure. Rob Flickenger, former O’Reilly editor, is currently publishing books to assist with this need. His first can be found at WNDW.net and is entitled â€œWireless Networks for the Developing Worldâ€. Itâ€™s available as a free PDF (40K downloads so far). It leads its readers through the design and security of a network to building low cost hardware. Work on the book has continued on the site’s wiki where the community has been adding case studies and links to other online wireless resources.
