Abstract

A beacon device is provided in proximity to said entity. A request to locate said entity is triggered on a central control unit. In response to the request to locate said entity, said control unit generates specification data for a unique radio signal identifier, sends an activation request and said specification data to said beacon device, and provides said specification data to a portable device and storing said specification data on the portable device. In response to receiving said activation request, said beacon device sends a radio signal identifier generated from said specification data. Signals are received on said portable device and compared with the specification data stored on the portable device. Based on the results of the comparison by said portable device, information is provided about at least one of a direction and distance to said entity. The location of said entity is detected using said direction information.
