AirPort Time Capsule works simultaneously on both the 2.4GHz and 5GHz bands, allowing all the devices on the network to automatically connect to the best available band for the fastest performance possible. All you have to do is connect your DSL or cable modem, then use the setup assistant built into iOS and Mac to quickly configure a secure network in just a few steps.
In addition to the 2TB or 3TB of storage in AirPort Time Capsule, you can turn any external USB hard drive into another secure drive to share across your Wi-Fi network and access securely over the Internet. You can also print documents, photos and more from any room in your home or office to a central printer connected to AirPort Time Capsule via USB. (See system requirements.) AirPort Time Capsule is protected with a built-in firewall and industry-standard encryption technologies including WPA/WPA2. And it works with Mac computers, PCs, iPad, iPhone, iPod touch, Apple TV and virtually all other 802.11a/b/g/n/ac Wi-Fi wireless devices — all at the same time.
