Time Capsule works simultaneously on both the 2.4GHz and 5GHz bands, allowing all the devices on the network to use the most efficient band automatically. All you have to do is connect your DSL or cable modem, then Time Capsule can quickly be set up with the easy-to-use AirPort Utility (available as a download for both Mac OS X and Windows).
Time Capsule also works great as a wireless hard drive, whether you have a Mac or a PC. It sets up in a snap, giving you a networked hard drive you can use for storing and sharing all kinds of files. You can even print documents, photos and more from any room in your home or office to a central printer connected to Time Capsule via USB. (See system requirements.) Of course, Time Capsule is protected with the built-in firewall and industry-standard encryption technologies including WPA/WPA2 and 128-bit WEP. And it works with Mac computers, PCs, iPad, iPhone, iPod touch, Apple TV and virtually all 802.11a/b/g/n Wi-Fi wireless devices — all at the same time.
