FCC Adopts Rules For Use of Television White Spaces
In its continuing efforts to promote efficient use of spectrum and to extend the benefits of such use to the public, the Federal Communications Commission (FCC) today adopted a Second Report and Order (Second R&O) that establishes rules to allow new, sophisticated wireless devices to operate in broadcast television spectrum on a secondary basis at locations where that spectrum is open. (This unused TV spectrum is now commonly referred to as television “white spaces”). The rules adopted today will allow for the use of these new and innovative types of unlicensed devices in the unused spectrum to provide broadband data and other services for consumers and businesses.
The rules represent a careful first step to permit the operation of unlicensed devices in the TV white spaces and include numerous safeguards to protect incumbent services against harmful interference. The rules will allow for both fixed and personal/portable unlicensed devices. Such devices must include a geolocation capability and provisions to access over the Internet a data base of the incumbent services, such as full power and low power TV stations and cable system headends, in addition to spectrum-sensing technology. The data base will tell the white space device what spectrum may be used at that location.
Wireless microphones will be protected in a variety of ways. The locations where wireless microphones are used, such as sporting venues and event and production facilities, can be registered in the data base and will be protected in the same way as other services. The Commission also has required that devices include the ability to listen to the airwaves to sense wireless microphones as an additional measure of protection for these devices.
All white space devices are subject to equipment certification by the FCC Laboratory. The Laboratory will request samples of the devices for testing to ensure that they meet all the pertinent requirements.
The Commission also will permit certification of devices that do not include the geolocation and data base access capabilities, and instead rely solely on spectrum sensing to avoid causing harmful interference, subject to a much more rigorous approval process.
