The original AirPort card was a modified PCMCIA card manufactured by Lucent. Lucent’s model was called the WaveLAN/Orinoco Gold PC card. Apple’s AirPort card had no integrated antenna and included a small antenna port along the top edge.
The AirPort card was designed to be installed by a user. It slid into a slot that was easily accessed, and a small cable was plugged into its antenna port. The antenna cable was integrated into the design of the Mac laptop or desktop. In some installations an adapter was required.
The original AirPort card was released along with the original iBook (blueberry and tangerine) and the original AirPort Base Station (graphite). Apple was among the first companies to release a complete wireless system that was accessible to consumers, providing computers designed to easily install wireless cards, the wireless card, a wireless base station, and software that was relatively easy to configure and set up.
