- television white spaces
Television white spaces (TVWS) is the name given to the gaps left in spectrum assignments as “guard” bands to prevent television signals from interfering with each other. They are called television white spaces because of the “white” noise signal that appears on a television in these unused bands. Nowadays, wireless technology has evolved so it can operate efficiently within these “guard” bands without interfering with television broadcast and they would not require a spectrum license as long as devices comply with regulatory standards. This opens up opportunities for offering access in regions that are traditionally hard to reach.
