NRB Warns FCC on White Spaces

National Religious Broadcasters warned the Federal Communications Commission that if it allows a proceeding on allowing unlicensed mobile devices to share the spectrum band with TV stations and wireless microphones on the assumption that the devices will eventually work without interference, it could be "one of the greatest technical blunders in our nation's history." Church groups are among those concerned that their wireless-mike use could be disrupted by the devices, like laptops and remote-sensing radios, which would operate in the so-called "white spaces" between channels used by TV stations and unlicensed microphones.
