About Your AirPort Card
1
With the AirPort Card installed in your computer, you can do the following:
m
Access an AirPort network at your work or school and use it to browse the Internet, send
and receive e-mail, and more.
m
Set up a direct link between two or more AirPort-equipped computers (known as a
“computer-to-computer” AirPort connection). You can use the link to play multiplayer
games.
m
Set up an AirPort network using your computer as a base station and provide Internet
access to other AirPort-equipped computers. You can also set up an AirPort network using
an external device called an “AirPort Base Station,” available from your Apple-authorized
dealer or The Apple Store at www.apple.com/store
About AirPort
AirPort technology offers an easy and affordable way to provide wireless Internet access
anywhere in your home or classroom. Instead of using traditional cabling to create a network,
AirPort uses wireless local area network (LAN) technology to provide wireless communication
between multiple computers.

How AirPort Works
In a traditional network, computers are connected through a series of wires that transfer
information between the different computers on the network. With AirPort, data is transferred
between computers over a wireless network using radio waves.
There are two ways to create a wireless network. When two or more AirPort-equipped
computers are in range of one another, they can use AirPort to communicate directly. This
connection is known as a “computer-to-computer” AirPort connection.
You can create a more permanent wireless network using a device known as a “base station.”
In this kind of network, all wireless communication goes through the base station to other
computers on the network or to the Internet.
How AirPort Provides Wireless Internet Access
The following are ways that you can use AirPort technology to provide Internet access to
AirPort-equipped computers:
m
Connect an AirPort Base Station (available from your Apple-authorized dealer or The Apple
Store at www.apple.com/store) to an existing network that already has Internet access, such
as in a school or small office.
m
Connect a telephone line, cable modem, or DSL modem to an AirPort Base Station. The
AirPort Base Station establishes an Internet connection and also creates a wireless network
though which multiple computers can get access to the Internet.
m
Share the Internet connection (phone line, cable modem, or DSL) of a single AirPortequipped computer with other wireless-equipped computers. When the other computers
need to access the Internet, all information passes through the computer with the Internet
connection.
Note:
To use AirPort to access the Internet, you must have an account with an Internet service
provider (ISP). In addition, you need to have a traditional way to access the Internet, either
through a phone line, cable, or DSL modem.
