  • Patent number: 11647479
    Abstract: The present invention relates to systems and methods for measuring signal strength emitted by a wireless portable device to determine the location of the wireless portable device. The wireless portable device may be located within a designated geographical location, premise or facility. The measurement involves two levels of transmissions. A first level involves a user's wireless portable device receiving signals from a plurality of beacons in the vicinity. The second level involves transmission of repeater signals from a mesh network. The payload of these signals, which may include a duress signal, includes the strength of the received beacon signals, so that when the duress signal is received by a controller, the signal strengths of both levels/types of transmissions can be determined. This two-level collection of signals is then processed by a neural network which have been previously trained to classify the signal collections into precise locations.
