Abstract: Systems and devices for detecting cellular signal jamming are disclosed. A cellular jamming detection system includes an antenna configured to receive radio frequency (RF) energy and a plurality of RF measurement channels associated with different cellular frequency bands. The RF measurement channels generate RF energy measurements representative of RF energy present within their respective frequency bands. Processing circuitry evaluates the RF energy measurements relative to reference RF energy levels to identify elevated RF energy within individual frequency bands and determines that a cellular jamming event has occurred based on identification of elevated RF energy in a plurality of the frequency bands. Upon detection of the cellular jamming event, the system generates an output indicative of the detected jamming condition.
