Using AirPort Wireless Networking
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.
Your computer is AirPort-ready. The only thing you need to add is an AirPort Card. You install
the AirPort Card in a slot inside the computer and connect it directly to the end of a built-in
antenna cable.
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 handset of the cordless phone makes a wireless connection to the base, which is
connected to the telephone line. Similarly, your computer makes a wireless connection to
the base station, which is connected to the telephone line or Ethernet network.
