Zusammenfassung:A rule-based machine learning system monitors frequency bands to detect transmissions from nearby active transmitters, such as those associated with wireless mobile devices. The system logs unique identifiers (UID) embedded in detected transmissions, recognizes patterns of UID detection over time, and selectively takes action when UIDs are detected and when they are expected but absent.
