A wireless WAN covers a broader geographic area. Cellular networks are used for data transmission, and
access is provided by a wireless service carrier.

can connect devices a short distance from one another, and is commonly used for connecting peripheral
devices to a computer, transferring data between hand-held devices and a personal computer, or remotely
controlling and communicating with devices such as mobile phones.
Establishing wireless LAN connections
Your computer comes with a built-in wireless network card and a conguration utility to help you make
wireless connections and monitor the status of your connection, so that you can stay connected to your
network while you are in the ofce, in a meeting room, or at home, with no need for a wired connection.
