| Summary: | © 2019, World Academy of Research in Science and Engineering. All rights reserved. Dynamic spectrum access (DSA) is one way to utilize and efficiently manage the frequency spectrum for wireless communications. One of DSA’s implementation at the physical and medium access and controls layers through cognitive radio (CR). CR and other DSA methods at those layers offer better solutions for reaching and interconnecting users or things, especially those in the rural areas, including unconnected internet-of-things (IoT) devices. This work aims to survey current technologies and standards for DSA. In particular, the comparisons are those of unutilized bands that were allocated for television broadcasting, which is known as television white space (TVWS). The paper provides an overview of TVWS, its elements, different architecture depending on the chosen application, and to show potential gaps for future techniques and technologies for TVWS systems and research. |
