TV White Space refers to the unused frequencies in the VHF and UHF television broadcast bands which are now available for unlicensed use. These frequencies were previously used for analog television broadcasts but became available for other uses following the transition to digital television. TV White Space technology allows for wireless communication over longer distances and through obstacles such as buildings and trees, making it suitable for rural broadband access, smart city applications, and IoT connectivity. Researchers in this area are exploring ways to optimize the use of TV White Space frequencies, improve device and network performance, and develop new applications for this technology.
