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.

Multi-level signal transmission system for wireless device location

According to an embodiment, an emergency communication (EC) system includes an emergency notification application for generating and receiving one or more emergency notification messages; a Websocket server for connecting one or more computing devices configured with the emergency notification application; a cloud-based storage server, wherein the storage server is configured for storing a plurality of rules for determining one or more actions to be taken in an emergency; and one or more communication channel identifiers for distributing the emergency notification messages to the one or more computing devices.
