TV White Space (TVWS) refers to TV channels which are not used by any licensed services at a particular location and at a particular time. To exploit this unused TVWS spectrum for improved spectrum efficiency, regulatory agencies have begun developing regulations to permit use of this TVWS by unlicensed wireless devices as long as they do not interfere with any licensed services. In the future many heterogeneous, and independently operated, wireless networks may utilize the TVWS. Coexistence

Consequently, IEEE 802 LAN/MAN standards committee has approved P802.19.1 standardization project to specify radio technology independent methods for coexistence among dissimilar or independently operated wireless devices and networks. In this paper we provide a detailed overview of the regulatory status of TVWS in the USA and Europe, analyze the coexistence problem in TVWS, and summarize existing coexisting mechanisms to improve coexistence in TVWS. The main focus of the paper is IEEE P802.19.1 standardization project, including its requirements and system design and major technical challenges ahead.
