Getting Started

AirPort offers the easiest way to provide wireless Internet
access and networking anywhere in the home, classroom,
or office.

AirPort is based on the latest Institute of Electrical and Electronics Engineers (IEEE)
802.11n draft specification and provides fast and reliable wireless networking in the
home, classroom, or small office. You can enjoy data transfer rates of up to five times
faster than data rates provided by the 802.11g standard and more than twice the
network range.

The new AirPort Extreme Base Station and the new Time Capsule are based on
simultaneous dual-band technology, so they work in both the 2.4 gigahertz (GHz)
or 5 GHz spectrum at the same time. And they are 100 percent backward-compatible,
so Mac computers and PCs that use 802.11a, 802.11b, 802.11g, or IEEE draft specification
802.11n wireless cards can connect to an AirPort wireless network. They also work
flawlessly with the AirPort Express for wireless music streaming and more. The
AirPort Extreme Base Station and Time Capsule have three additional 10/100/1000Base-
T Gigabit Ethernet ports, so you don’t need to include another router in your network.

To set up an AirPort Extreme Base Station, an AirPort Express, or a Time Capsule, you
use AirPort Utility, the easy-to-use setup and management application. AirPort Utility
has a simple user experience, with all software controls accessible from the same
application. It provides better management of several Apple wireless devices, with
client-monitoring features and logging.

If you’re using AirPort Utility version 5.4 or later, you can set up a guest network, in
both the 2.4 GHz and 5 GHz bands, so that guests can connect to the Internet using
your AirPort network, while you keep your private network secure. You can also choose
to set up guest accounts that expire, to grant temporary access to your network; you
no longer need to give your network password to visitors in your home or office.
You can even set up accounts with time constraints for the best in parental controls.
AirPort Utility supports IPv6 and Bonjour, so you can “advertise” network services such
as printing and sharing a hard disk over the Wide Area Network (WAN) port.
