This paper describes an experimental testbed that combines wireless microphone sensors with a web-based Terrestrial Digital Video Broadcasting (DVB-T) geo-location database and a Programme Making and Special Events (PMSE) spectrum-booking platform. Software Defined Radios (SDR) and Internet technologies are the enabling tools in use. The key sensing techniques are identified and implemented. Test trials, in a real scenario, have shown that the platform was able to gather information from a
DVB-T geo-location database and a PMSE spectrum-booking platform, and update the list of vacant channels with blind sensing techniques. The proposed method has shown capabilities to protect primary users of interferences from secondary users of the spectrum.
