AirPort is Apple’s Implementation of IEEE 802.11b
Basically it’s wireless networking - allowing speeds of up to 11Mbps at a range of about 150 feet from the base-station.
To use Airport you will need an AirPort card and a compatible Mac.
update: (Jan 2003)
Apple has announced AirPort Extreme (802.11g) - circa 50Mbps
(Does anyone else hate the Apple “Extreme” branding? It sounds so 80s - What’s next Radical Ethernet? Bodacious Bluetooth?) - DiggoryLaycock
