The card supports Multiple Input Multiple Output (MIMO), which enables multiple concurrent data stream transmission. It supports WEP, WPA and WPA security protocols as well as AES and TKIP. It works with all AirPort Extreme and AirPort Express base stations, as well as other wireless hubs.
The PCI card works in any PCI or PCI-X slot-equipped Macs, including Power Mac G4s (except for the Cube) and Power Mac G5 with PCI or PCI-X slots. System requirements call for Mac OS X 10.4 or later.
