Abstract

A method of determining a relative location of one or more access controls is provided. The method including: detecting a first wireless signal from a first access control; determining a unique device identifier (UDID) for the first access control in response to the first wireless signal; determining a received signal strength indicator (RSSI) of the first wireless signal; and generating a location fingerprint to associate the RSSI of the first wireless signal with the UDID for the first access control.

Claims (52)

1. A method of determining a relative location of one or more access controls, the method comprising:

detecting a first wireless signal from a first access control of the one or more access controls;

determining a unique device identifier (UDID) for the first access control based on to the first wireless signal;

determining a received signal strength indicator (RSSI) of the first wireless signal; and

generating a location fingerprint to associate the RSSI of the first wireless signal with the UDID for the first access control,

wherein the relative location is a location of each of the one or more access controls relative to each other, and

wherein each of the one or more access controls is a door lock or a turnstile lock.

2. The method of claim 1 , further comprising:

transmitting the location fingerprint to a server.

3. The method of claim 2 , wherein the location fingerprint is transmitted to the server through a smart phone.

4. The method of claim 2 , wherein the server is configured to update a location fingerprint array based on the location fingerprint.

5. The method of claim 2 , wherein the server is configured to determine a location of a smart phone based on the location fingerprint array and a distance between the first access control and the smart phone.

6. The method of claim 1 , further comprising:

detecting a second wireless signal from the first access control;

determining the UDID for the first access control based on the second wireless signal;

determining an RSSI of the second wireless signal; and

updating the location fingerprint of the UDID for the first access control based on the RSSI of the second wireless signal.

7. The method of claim 1 , further comprising:

detecting a second wireless signal from a second access control;

determining a UDID for the second access control based on the second wireless signal;

determining an RSSI of the second wireless signal; and

updating the location fingerprint to associate the RSSI of the second wireless signal with the UDID for the second access control.

8. The method of claim 7 , further comprising:

transmitting the location fingerprint to a server.

9. The method of claim 8 , wherein the location fingerprint is transmitted to the server through a smart phone.

10. The method of claim 8 , wherein the server is configured to update a location fingerprint array based on the location fingerprint.

11. The method of claim 8 , wherein the server is configured to determine a location of a smart phone based on the location fingerprint array and a distance between the smartphone and at least one of the first access control and the second access control.

12. A computer program product tangibly embodied on a computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:

detecting a first wireless signal from a first access control of one or more access controls;

determining a unique device identifier (UDID) for the first access control based on the first wireless signal;

determining a received signal strength indicator (RSSI) of the first wireless signal; and

generating a location fingerprint to associate the RSSI of the first wireless signal with the UDID for the first access control,

wherein the relative location is a location of each of the one or more access controls relative to each other, and

wherein each of the one or more access controls is a door lock or a turnstile lock.

13. The computer program product of claim 12 , wherein the operations further comprise:

transmitting the location fingerprint to a server.

14. The computer program product of claim 13 , wherein the location fingerprint is transmitted to the server through a smart phone.

15. The computer program product of claim 13 , wherein the server is configured to update a location fingerprint array based on the location fingerprint.

16. The computer program product of claim 13 , wherein the server is configured to determine a location of a smart phone based on the location fingerprint array and a distance between the first access control and the smart phone.

17. The computer program product of claim 12 , wherein the operations further comprise:

detecting a second wireless signal from the first access control;

determining the UDID for the first access control based on the second wireless signal;

determining an RSSI of the second wireless signal; and

updating the location fingerprint of the UDID for the first access control based on the RSSI of the second wireless signal.

18. The computer program product of claim 12 , wherein the operations further comprise:

detecting a second wireless signal from a second access control;

determining a UDID for the second access control based on the second wireless signal;

determining an RSSI of the second wireless signal; and

updating the location fingerprint to associate the RSSI of the second wireless signal with the UDID for the second access control.

19. The computer program product of claim 18 , wherein the operations further comprise:

transmitting the location fingerprint to a server.

20. The computer program product of claim 19 , wherein the location fingerprint is transmitted to the server through a smart phone.
