Patent ID: 10111101

Abstract:
Wireless communication of information from an access control device to a mobile communications device is disclosed. The mobile communications device is capable of communicating with at least two transmitters. The at least two transmitters include i) a first transmitter located at a first access controlled door that transmits first BLE beacons; and a ii) second transmitter located at a second access controlled door that transmits second BLE beacons. The mobile communications device includes a Bluetooth communication module that is configured to receive a plurality of BLE beacons, including the first BLE beacons and the second BLE beacons, from the at least two transmitters at different locations on a same floor within a premises. The mobile communications device also includes a microprocessor that is configured to execute instructions to determine a location of the mobile communications device based at least in part on signal properties of the first and second BLE beacons, beacon-identifying information contained in the first and second BLE beacons, and known locations of the first and second access controlled doors. The mobile communications device also includes a display that is configured to output text or graphics to inform a device user of the location of the mobile communications device relative to at least the first and second access controlled doors.
