AirPort Extreme Wireless Internet and Networking
Your iMac G5 is AirPort Extreme-ready. If you ordered an AirPort Extreme Card when
you purchased your iMac G5, the card is already installed. If you do not have an AirPort
Extreme Card installed and would like to install one, see page 47 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. Previous models of
AirPort Card are not compatible with your computer. You also need an 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 station, which is connected to the Internet via a telephone line
or a DSL or cable modem.
