AT&T's new device is what's known as a femtocell: a machine that plugs into your existing high-speed Internet connection and then broadcasts a cell phone signal throughout your house (or office or mountain lair, etc.). You then make and receive calls on your phone as usual, but the femtocell actually routes your calls over the Internet to your wireless carrier's network.
