Back up a lifetime's worth of memories with Time Capsule, a wireless hard drive that works seamlessly with Time Machine in Mac OS X Leopard and Snow Leopard. It's also a full-featured 802.11n Wi-Fi base station with simultaneous dual-band support. Guest networking - Set up a separate Wi-Fi network with a separate password for your visitors.

It sets up in a snap, giving you a networked hard drive you can use for storing and sharing all kinds of files. Print without wires - Print documents, photos and more from any room in your home or office to a central printer connected to Time Capsule via USB. Strong security and access controls - Protect yourself with the built-in firewall and industry-standard encryption technologies including WPA/WPA2 and 128-bit WEP.
