Open Up The Spectrum to Promote Innovation, Scientists Say
The portion of the spectrum that is freed up as terrestrial television broadcasting is being replaced by cable and internet-based TV should be opened up for unlicensed use to stimulate innovation, German scientists argue. In the 2000s Wi-Fi started competing with cellular networks. The latter were maintained by large telco's who had spent billions on licensing spectrum and maintaining and upgrading infrastructure to provide primarily voice communication services for paying customers. As mobile...
