Apple AirPort Express v4.2 - Manual (Page 5)

Getting Started 5
 Set up a wireless connection to your Ethernet network. AirPort and AirPort Extreme-
equipped Macintosh computers or Windows XP or 2000 computers can then have
access to an entire network without being connected with a cable.
 Extend the range of your network by adding AirPort Express to your existing AirPort
Extreme or AirPort Express wireless network (this is called a Wireless Distribution
System, or WDS).
 Connect a USB printer to your AirPort Express. All of the compatible computers on
the AirPort network, both wireless and wired, can print to it.
 Create custom profiles so you can store settings for up to five different locations. Take
AirPort Express with you on the road, and quickly connect to broadband networks,
such as in a hotel room.
