Dual band wideband chirp channel sounder receiver for spectrum occupancy measurements

Over the last decade, it has been found that the radio spectrum is underutilized in time, frequency and space dimensions or any of their combination. Spectrum occupancy measurements provides a knowledgebase to quantify spectrum utilization and more importantly valuable to define opportunistic spectrum access methods where unused portion of the radio spectrum can be reutilized, to improve utilization, provided its interference free to local users of the network.
