First Claim
1. A system, comprising:
- a plurality of reference tags affixed to reference locations in a coverage area and configured to form a wireless mesh network;
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 being configured to send a first signal in response to an event, wherein the call tag operates in a sleep mode and includes a motion sensor, wherein the motion sensor is active in the sleep mode, wherein the call tag is woken out of the sleep mode on a first periodic basis to communicate with the reference tags and to collect the data, wherein the call tag is woken out of the sleep mode at a second periodic basis in response to a motion signal from the motion sensor, the second periodic basis being more frequent than the first periodic basis;
a positioning system coupled to the wireless mesh network and configured to receive the first signal and the data collected by the call tag, the positioning system being configured to process the data collected by the call tag to determine the call tag location with respect to the plurality of reference tags wherein the data is related to signal strengths of signals from the reference tags to the call tag; and
a portable electronic device configured to communicate with the wireless mesh network and configured to receive the call tag location from the positioning system.

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.
