Title: SYSTEMS AND METHODS FOR INDOOR TRACKING VIA WI-FI FINGERPRINTING AND ELECTROMAGNETIC FINGERPRINTING
Abstract: Systems and methods for indoor tracking via Wi-Fi fingerprinting and electromagnetic fingerprinting are provided and can include a gateway receiver device measuring a RSSI value of a signal transmitted by a Wi-Fi transmitter device, the gateway receiver device measuring an EMF value of an interference in an electromagnetic field created by the gateway receiver device that is caused by the Wi-Fi transmitter device, the gateway receiver device determining whether the RSSI value matches any of a plurality of Wi-Fi fingerprints associated with a monitored region and whether the EMF value matches any of a plurality of electromagnetic fingerprints associated with the monitored region, and responsive thereto, the gateway receiver device identifying that a location of the Wi-Fi transmitter device is within the monitored region.

Claims: number: 1
text: A method comprising:
number: 2
text: The method of claim 1 further comprising the gateway receiver device using a Wi-Fi transceiver of the gateway receiver device to measure the RSSI value.
number: 3
text: The method of claim 1or claim 2 further comprising:
number: 4
text: The method of claim 1, 2 or 3 further comprising the gateway receiver device transmitting the RSSI value and the EMF value to a server device to determine whether the RSSI value matches any of the plurality of Wi-Fi fingerprints associated with the monitored region and whether the EMF value matches any of the plurality of electromagnetic fingerprints associated with the monitored region.
number: 5
text: The method of claim 4 further comprising the server device comparing the RSSI value to a plurality of Wi-Fi fingerprints associated with the monitored region and stored in a database on the server device and comparing the EMF value to a plurality of electromagnetic fingerprints associated with the monitored region and stored in the database.
number: 6
text: The method of claim 5 further comprising:
number: 7
text: The method of any preceding claim further comprising:
number: 8
text: The method of claim 7 wherein the loT device is an HVAC system, and wherein the command includes instructions to raise or lower a temperature of the monitored region.
number: 9
text: The method of any preceding claim wherein the Wi-Fi transmitter device is included in or a part of a wearable device or a mobile device.
number: 10
text: The method of claim 9 wherein the Wi-Fi transmitter device is included in or a part of a smartphone.
number: 11
text: The method of any preceding claim further comprising the gateway receiver device using a BLE-based transceiver of the gateway receiver device to measure the RSSI value, wherein the Wi-Fi transmitter device is or includes a BLE device.
number: 12
text: A system comprising:
number: 13
text: The system of claim 12 further comprising a second transceiver that transmits the RSSI value and the EMF value to a server device to determine whether the RSSI value matches any of the plurality of Wi-Fi fingerprints associated with the monitored region and whether the EMF value matches any of the plurality of electromagnetic fingerprints associated with the monitored region.
number: 14
text: The system of claim 13 further comprising the server device, wherein the server device compares the RSSI value to a plurality of Wi-Fi fingerprints associated with the monitored region and stored in a database on the server device and compares the EMF value to a plurality of electromagnetic fingerprints associated with the monitored region and stored in the database.
number: 15
text: The system of claim 14 wherein the Wi-Fi transceiver and the programmable processor measure and map the plurality of Wi-Fi fingerprints and store the plurality of Wi-Fi fingerprints in the database, and wherein the electromagnetic object and the programmable processor measure and map the plurality of electromagnetic fingerprints and store the plurality of electromagnetic fingerprints in the database.
