System design to enable coexistence in TV white space

One of the newest bands allowed for unlicensed device operation is called TV white space. It occupies partially UHF and VHF bands, which were reserved for licensed terrestrial TV broadcasting. New regulations throughout the world enable unlicensed use of TV white space if and only if no harmful interference is created to licensed devices. On the other hand, interference between unlicensed devices is not regulated. There is no doubt that a system which enables coexistence between unlicensed users in TV white space would be beneficial. This paper provides design overview for such a system and research activities conducted to realize it.
