Regulatory, trials and standardization efforts are also described to see how this technology evolves over time from concept to maturity. With certain level of maturity, various possible applications of TVWS are discussed to give readers some perspectives of the great potential of TVWS technology. The various TVWS related technologies are then discussed based on the current landscapes.
