AirPort Wireless Internet and Networking
Your PowerBook is AirPort-ready. The computer has built-in antennas, and if you ordered an
AirPort Extreme Card when you purchased your PowerBook, a card is already installed. If you
do not have an AirPort Extreme Card installed and would like to install one, see page 69 for
more information.
AirPort offers an easy and affordable way to provide wireless Internet access anywhere in the
home, at work, or in the classroom. Instead of using traditional cables, AirPort uses wireless
local area network (LAN) technology to provide wireless communication between multiple
computers. Through a wireless network you can set up access to the Internet, transfer files,
play multiplayer games, and more.
Note: Wireless Internet access requires an AirPort Extreme Card, AirPort Base Station, and
Internet access (fees may apply). Some Internet service providers are not currently
compatible with AirPort. Range may vary with site conditions.
How AirPort Provides Wireless Internet Access
With AirPort, you set up a wireless connection to a device known as a base station, which has
a physical connection to the Internet. AirPort technology works like a cordless telephone.
The AirPort Extreme Card in the computer makes a wireless connection to the base, which is
connected to the telephone line or a DSL or cable modem.
