Femtocells are tiny cellular base stations that consumers will soon be able to install in homes, scaled-down versions of the refrigerator-size racks of equipment that nestle beneath cell towers and carry your conversations as you speed down the highway. Early prototypes are not much bigger than a TV dinner.
Plugged into your high-speed Internet connection, they'll communicate with your existing cellphone whenever you're at home, and send your calls over the Internet. The benefits are better coverage, faster data speeds, and longer battery life for your handset - since it no longer has to communicate with a cell tower that may be a mile away.
