This book consists of many short, focused topic features that answer all the typical questions newcomers ask, such as "how does this work? how do I do it?" without losing the reader or a sense of humor. Duntemann explains the complex security issues clearly, and shows how users can protect themselves from both obvious and non-obvious threats. He expands the blizzard of WiFi acronyms and touches on the human element in the WiFi movement, including hacker threats and WiFi weirdness. The unique FAQ-index feature allows readers to zero in on precisely what they need to know without plowing through unrelated text. Many technical figures clarify difficult concepts, with abundant Web pointers to further information.
