<b>Simultaneous dual-band support.</b>
Some Wi-Fi devices use the 2.4GHz wireless band, including iPhone, iPod touch, and devices using 802.11b/g. Other devices can use either 2.4GHz or the higher-speed 5GHz band, such as the latest 802.11n-based Mac computers, iPad and Apple TV. Instead of choosing one of the bands, AirPort Extreme operates simultaneously on both bands, and your multiband devices automatically use the best available band. This means all your Wi-Fi devices get the fastest possible wireless performance and the best possible range. In addition, AirPort Extreme reduces the possibility of interference from appliances and cordless phones that use the 2.4GHz band.
<b>Even faster performance.</b>
Based on the IEEE 802.11n specification, AirPort Extreme uses a technology called multiple-input multiple-output (MIMO) to transmit multiple data streams simultaneously. The result? AirPort Extreme delivers data transfer speeds up to five times those of 802.11g wireless networks — while achieving up to twice the range.
<b>Imagine the possibilities.</b>
Up to 50 people can all share the same Internet connection, exchange files using the file-sharing capability built into Mac OS X or Windows, access local and remote file servers, annihilate the competition in multiplayer games — anything a typical network user can do, plus a number of things that are decidedly not typical, such as wireless storage and printing.
<b>Share the Internet securely with guest networking.</b>
It’s easy to allow guests to use your Internet connection without sharing your password or giving them access to the rest of your network. Simply enable the guest networking feature using the AirPort Utility application and create a separate Wi-Fi network just for your friends. You can set up this guest network with a different password or with none at all. Your primary network — including your printer, attached drives, or other devices — remains secure.
<b>Compatible with 802.11a/b/g.</b>
All currently shipping Mac and iOS devices support the latest 802.11n technology in the AirPort Extreme Base Station. And AirPort Extreme is compatible with Mac computers, PCs, and wireless devices such as iPad, iPhone, and iPod touch that use 802.11a, b, or g technologies. You can also rest assured that AirPort Extreme works with other Wi-Fi certified 802.11n products.
