The paper provides a synopsis and analysis of television white space (TVWS), its fundamental aspects, elements, and architectures. This shows disparities between techniques and technologies that may lead to potential gaps for TVWS advanced systems and exploration. TVWS are those unutilized bands that were allocated for television broadcasting. In particular, this can be used for interconnecting wireless users and sensors, especially those in outland areas. This intends to spread the determined system of interrelated devices and networks. The TVWS corresponds to one of the definitive approaches of dynamic spectrum access (DSA), which takes advantage of and adeptly manages the complimentary frequency spectrum for wireless communications. Cognitive radio (CR) in dispersion of DSA's implementation at the physical, medium access, and control layers offers sophisticated methods for encompassing and interconnecting users or things. Substantially, this work also aims to survey technologies and standards for DSA and collate it with the TVWS approach.
