The popularity of wireless networking has grown exponentially over the past few years, despite a general downward trend in the telecommunications industry. More and more computers and users worldwide communicate via radio waves every day, cutting the tethers of the cabled network both at home and at work. Wireless technology changes not only the way we talk to our devices, but also what we ask them to do. With greater flexibility, broader range, and increased mobility, wireless networks let us live, work, and think differently. Wireless networks also open up a vast range of tasty new hack possibilities, from fine-tuning network frequencies to hot-rodding handhelds. The second edition of Wireless Hacks , co-authored by Rob Flickenger and Roger Weeks, brings readers more of the practical tips and tricks that made the first edition a runaway hit, selling nearly 30,000 copies.
