Everyone in your family can surf the web wire-free because AirPort Express provides simultaneous wireless Internet access via your DSL or cable modem for up to 10 computers. Just like its big brother, AirPort Extreme, AirPort Express uses the 802.11g wireless standard to deliver blazing data rates - up to 54 Mbps. It supports both Macs equipped with an AirPort Extreme Card and Wi-Fi-compliant 802.11g Windows PCs, as well as Macs with the older AirPort Card and 802.11b Windows PCs. Have several computers in your home but only one printer? No problem. Just connect a printer to the USB port on the AirPort Express Base Station and the printer instantly becomes available to everyone on your wireless network.AirPort Express with AirTunes brings your iTunes music in your Mac or PC into your living room - or wherever in your home you have a stereo or a set of powered speakers.
