You may not know it, but if you have a wireless router, a cordless phone, remote car-door opener, baby monitor or cellphone in your house, the FCC claims the right to enter your home without a warrant at any time of the day or night in order to inspect it. That's the upshot of the rules the agency has followed for years to monitor licensed television and radio stations, and to crack down on pirate radio broadcasters. And the commission maintains the same policy applies to any licensed or unlicensed radio-frequency device. "Anything using RF energy -- we have the right to inspect it to make sure it is not causing interference," says FCC spokesman David Fiske. That includes devices like Wi-Fi routers that use unlicensed spectrum, Fiske says.
