Party Central.If you already have a wireless network in place, you can use AirPort Express to add music to its capabilities. Let’s say, for example, you have AirPort Extreme set up in your den. There’s no need to scrap this setup and create a whole new network. Simply connect AirPort Express to your stereo in your favorite music room and plug it into an electrical outlet — it wirelessly links to your existing network, letting you play your music in your room of choice without moving anything or connecting anything else.

(1) The AirPort Express Base Station is based on an IEEE 802.11n draft specification and is compatible with IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g. (2) Based on a comparison with Apple's 802.11g products. Comparison assumes AirPort Express network with 802.11n-enabled computer. Speed and range will be less if an 802.11a/b/g product joins the network. Accessing the wireless network requires an AirPort- or AirPort Extreme-enabled computer or other Wi-Fi Certified 802.11a/b/g-enabled computer. Actual performance will vary based on range, connection rate, site conditions, size of network, and other factors. Range will vary with site conditions. (3) Wireless Internet access requires a wireless-enabled computer, a base station or other access point, and Internet access (fees may apply). Some ISPs are not currently compatible with AirPort Express.
