There is currently a movement to allow the operation of personal unlicensed, wideband digital devices in the UHF television spectrum in the United States. These devices are backed by firms which seek to develop and deploy these devices as quickly as possible. These 'white space' devices (WSDs) will be required to have GPS and access to a location database to avoid interfering with other users of the band. Initial tests performed by the FCC have shown that in some cases, prototypes of these devices are unable to correctly identify frequencies that are in use, and may therefore accidentally transmit on top of these users. Broadcasters, theaters, and wireless microphone manufacturers are firmly against these types of devices ostensibly for this reason.

Later tests by the FCC [7] indicate that the devices can safely be used. This has not reduced the opposition by broadcasters who may also be concerned by the possibility of entertainment delivery competition from high-speed mobile Internet access delivered in the white spaces. A decision on whether and under what rules to allow these devices is on the docket for the November 4, 2008 meeting of the FCC.
