How Wireless Works continues in the How It Works series tradition by explaining every aspect of wireless communications, from the remote control on your coffee table to the most sophisticated wireless Internet networks. As wireless technology proliferates, readers will need to understand how wireless technologies work in order to make educated buying and business decisions related to wireless technologies. This book will provide readers with a basic technical background on wireless technologies, including infrared, radio-frequency, power line, and PNA (wireless home networking.) The book will also explain the strengths and weaknesses of each technology, so the reader will understand which technology is best suited to a particular application. Where appropriate, we’ll explain the differences between competing industry standards, so readers can make an informed buying decision.
