Query: quick intro to wireless computing

For the raw beginner in wireless computing, Carter offers quick and easy education. He describes the main modes of usage. This is mostly a hardware book, because you have to decide what types of devices you need to buy, to enable your wireless interaction. The text is pitched towards someone on her own; doing personal computing in her home or small office, and without a tech staff to ask for help.Significant space is also devoted to using your laptop in a wireless mode when travelling. Be careful about exposing your communications as clear text, that can easily be evesdropped by anyone nearby. But Carter shows how if you drive about a typical American city, you can often find WiFi hotspots that are free to connect to. (Though sometimes this might be inadvertant on the part of their owners!)
