Abstract

The system comprises a plurality of reference tags affixed to reference locations in a coverage area and configured to form a wireless mesh network. The system also includes a call tag configured to communicate with the plurality of reference tags and to collect data regarding the communication with the plurality of reference tags. The call tag is configured to send a first signal in response to an event. A positioning system is coupled to the wireless mesh network and configured to receive the first signal and the data collected by the call tag. The positioning system is further configured to process the data collected by the call tag to determine the call tag location with respect to the plurality of reference tags. A portable electronic device is configured to communicate with the wireless mesh network and configured to receive call tag location from the positioning system.
