ABSTRACT
Inability to obtain frequency spectrum for meeting the surge in demand for wireless solutions has been a worldwide problem. The recent advancement in TV White Space (TVWS), which uses frequency spectrum opportunistically when the incumbent users are not utilizing these spectrums, shed some lights into opportunities of reusing the underutilized spectrums. At the same time, utility companies are also trying to ride on the digital bandwagon, especially digital communications, in order to increase their efficiency and robustness. There have been several attempts to apply TVWS onto various applications, but none seems to be more promising than the application of TVWS onto Smart Grid. In this paper, we discuss about the issues on the current Smart Grid system and explain why TVWS is a good choice for Smart Grid. We then further elaborate the system architecture of our TVWS Smart Grid solution. With this system, it is hoped that a better Smart Grid can be built to better utilize energy and provide a greener environment for the future.
