There’s a Bluetooth in your future. No, this isn’t the kind of blue tooth that requires expensive

dental whitening. This Bluetooth is a technology that promises to eliminate most of the cables

that connect your various personal computing devices—and to create new types of smart

wireless communications.

This book is your guide to Bluetooth, a consumer-level overview of the technology and its

possible applications. Throughout the rest of this book you’ll learn all sorts of details about

Bluetooth—what it is, what it does, how it does it, and how you’ll use it. Before we get to

those details, however, this chapter provides you with a general overview of the Bluetooth

technology. So even if you’ve never heard of Bluetooth before, you’ll find out what all the

fuss is about—and discover how and why you’ll soon be using Bluetooth technology in your

daily life.
