Linux Unwired

Book description

In Linux Unwired, you'll learn the basics of wirelesscomputing, from the reasons why you'd want to go wireless in thefirst place, to setting up your wireless network or accessingwireless data services on the road. The book provides a completeintroduction to all the wireless technologies supported by Linux.You'll learn how to install and configure a variety of wirelesstechnologies to fit different scenarios, including an office orhome network and for use on the road. You'll also learn how to getWi-Fi running on a laptop, how to use Linux to create your ownaccess point, and how to deal with cellular networks, Bluetooth,and Infrared. Other topics covered in the book include:

  • Connecting to wireless hotspots

  • Cellular data plans you can use with Linux

  • Wireless security, including WPA and 802.1x

  • Finding and mapping Wi-Fi networks with kismet and gpsd

  • Connecting Linux to your Palm or Pocket PC

  • Sending text messages and faxes from Linux through yourcellular phone

  • Linux Unwired is a one-stop wireless information source foron-the-go Linux users. Whether you're considering Wi-Fi as asupplement or alternative to cable and DSL, using Bluetooth tonetwork devices in your home or office,or want to use cellular dataplans for access to data nearly everywhere, this book will show youthe full-spectrum view of wireless capabilities of Linux, and howto take advantage of them.
