Abstract
A beacon detection system which can locate a missing search subject includes: a beacon signal receiver; a location position detector; and a beacon detector. The detector is configured to detect a location of a broadcasting beacon signal associated with a personal device of a search subject within search data covering a geographic search area derived from a search for the search subject, the search data gathered by the beacon signal receiver and location position detector. A computer implemented method of determining a location of a search subject is also provided. The method determines at least a possible connection request from Wi-Fi signals in search data gathered by a Wi-Fi radio covering a geographic search area for a search subject and associated location information to locate the search subject.
