Abstract

An intelligent spectrum management (ISM) system and method that includes sophisticated features to detect, classify, and locate sources of RF activity. The system comprises one or more radio sensor devices positioned at various locations in a region where activity in a shared radio frequency band is occurring. A server is coupled to the radio sensor devices and aggregates the data generated by the sensor devices. The server receives data from each of the plurality of sensor devices and executes functions to process the data. One feature of the system is to correlate data collected from the sensor or from suitably equipped devices that operate (and may move about) in a space with locations where provocation of that data occurs. To this end, radio frequency energy is received at each of a plurality of known positions (e.g., the sensors) in a space. The positions in the space of one or more devices emitting radio frequency energy in the space is determined from the received radio frequency energy at the plurality of known positions (e.g., the sensors). A variety of positioning techniques may be employed, such as received signal strength, time-difference-of arrival, time-of-arrival, etc. Activity data representing characteristics of received radio frequency energy in the space is generated at the sensors or at suitable equipped devices that may move about the space. The server correlates the activity data with the positions in the space that are associated with the provocation of the activity data.
