To meet the growing wireless demand for bandwidth we need more spectrum. However, most of the prime spectrum has been allocated by the regulatory agencies. For the past 10 years, we have been exploring the use of Dynamic Spectrum Access (DSA) as a paradigm to operate in unused portions of the allocated spectrum. In this talk, I will present two aspects of our work, First, on the TV white spaces, and how we are currently using the technology to connect villages and universities in Africa, and second, on a measurement framework to study spectrum occupancy from 30 MHz to 5 GHz, and how this framework can help unlock several new portions of spectrum for DSA, similar to the TV white spaces.
