The Apple AirPort Base Station is actually the equivalent to a stripped-down computer with a 56k modem, 10Mbps Ethernet Card, and a Lucent/Orinoco WaveLAN Silver PCMCIA card, all packed into a flying-saucer shaped case less than 1 foot in diameter.

The AirPort card available for Apple laptops and iMacs is simply a re-branded Lucent/Orinoco card that uses the computer's built-in antenna that is located around the screen.

The Lucent cards used are the same ones marketed for PC's.

This information was obtained from a Lucent representative at Networld+Interop Atlanta 2000. Verity of all above statements depends upon that individual's knowledge of their product.
