What This Book Covers

This book explains how to use the following wireless technologies
with Linux:

Wireless Fidelity (Wi-Fi)

Wi-Fi is short-range wireless networking that supports raw speeds up
to 54 Mbps (about 20-25 Mbps actual speeds). It''s an
affordable replacement for wired Ethernet, and includes the 802.11b,
802.11g, and 802.11a protocols. Chapter 1
through Chapter 6 discuss Wi-Fi.

Bluetooth

Bluetooth is a wireless cable-replacement that allows you to get rid
of USB and serial cables. You can use it to connect a Personal
Digital Assistant (PDA), such as a Palm or Pocket PC, to Linux;
create an ad-hoc network; or transfer files between computers.
Bluetooth is covered in Chapter 7.

Infrared

Infrared has been available for a long time, and in some cases,
it''s the only way that two devices will talk to each
other, particularly with older PDAs. Infrared uses light waves that
are just outside the range of visible light. Infrared is covered in
Chapter 8.

Cellular networking

Although Wi-Fi is fast and reliable, it disappears the moment you
leave its useful range. Cellular networks cover large areas, reach
speeds between 40 kbps and 100 kbps, and even work reliably while you
are in a moving vehicle. With unlimited data plans starting at $19.99
a month from some providers, cellular data plans can be a useful
complement to Wi-Fi. Chapter 9 covers cellular
data.

Global Positioning System (GPS)

Use a GPS to figure out your location in two or three dimensions.
Plugged into a Linux computer, a GPS device becomes a source of
location data that can be combined with freely available maps to plot
locations of wireless networks, figure out where you are, or map out
whatever interests you. GPS is covered in Chapter 10.
