White Spaces (White Space Spectrum) - White Spaces are unused TV airwaves. These “white spaces” can be found between channels 2 and 51 (except for channel 37) on televisions that are not hooked up to satellite or cable. Older TV transmission technologies required more “space” between occupied channels to guard against interference. But today’s digital technologies are more efficient and precise. White Space Spectrum could be used for content transmission, including wireless broadband services, as well as to stream video and audio throughout a house without the need for cumbersome wires. https://en.wikipedia.org/wiki/White_spaces_(radio)
