how does wifi work?

By Matt Anniss

Book Overview

Even though computer wireless networks haven't been around for very long, the basic technology used to create them is more than 100 years old. WiFi uses radio waves to send and receive data and connect smartphones, tablets, and computers to the Internet. Today, almost everywhere you go has WiFi, including schools, coffee shops, and the library. The inner workings of this ubiquitous technology will fascinate readers, who probably use it every day. Accompanied by full-color photos, the main content will introduce innovators like Nikola Tesla and other electronics history, as well as the future possibilities of wireless connection.
