America’s first public “WhiteFi” network, leveraging spectrum previously occupied by analog TV channels, has been launched in North Carolina. Running at 1.5 to 3.1 MB/sec., the service will initially be used mostly for municipal functions such as surveillance cameras and transmitting water quality data, according to reports. White space networking — sometimes also known as “WhiteFi” — relies on radio spectrum that was previously reserved for TV stations. Because available frequencies vary from location to location, the technology involves access points and clients fitted with cognitive radio equipment, which can detect interference and automatically switch frequencies when they need to.
