The National Association of Broadcasters has expressed their concerns towards the use of unlicensed broadband service in white spaces. All events that use wireless microphones will be negatively affected; to include football games, concerts, wireless microphone companies, etc.
Google believes that the use of the white space poses no risk to the concerned parties. White Space devices that are due to launch February 2009, would rely on “all clear signals from a database of licensed transmitters or a geo-located device with access to that database.” Devices that don’t operate like this will not transmit at all. To prevent interference with radio astronomy services, channels 36 though 38 would be not be available to white space broadband; of which channel 37 is used for medical devices.
