Abstract

The present disclosure relates to computer-implemented methods and systems for determining the location of an access point. An example method may include receiving a plurality of data elements from a plurality of mobile devices. Each data element includes at least an indoor location of a respective mobile device. Each data element further includes a list of one or more radio frequency devices in the vicinity of the respective mobile device, and an indication of a signal strength between each of the one or more radio frequency devices in the vicinity of the respective mobile device and each respective mobile device. The method may also include analyzing the plurality of data elements to determine a location for a radio frequency device in the list of radio frequency devices. Furthermore, the method may include adding the determined location for the radio frequency device to a database.

Claims

1. A method, comprising:

receiving, by a computing device comprising one or more processors, a plurality of data elements from a plurality of mobile devices, wherein each data element includes at least;

(i) an indoor location of a respective mobile device, (ii) a list of one or more radio frequency devices in the vicinity of the respective mobile device, and (iii) an indication of a signal strength between each of the one or more radio frequency devices in the vicinity of the respective mobile device and each respective mobile device;

analyzing, by the computing device, the plurality of data elements to determine a location for a radio frequency device in at least one of the list of radio frequency devices; and

adding, by the computing device, the location for the radio frequency device to a database.

2. The method of claim 1, wherein each data element further includes an estimated accuracy of the indoor location of a respective mobile device.

3. The method of claim 2, wherein analyzing the plurality of data elements to determine at least one location for a radio frequency device in the list of radio frequency devices includes filtering data elements with an estimated accuracy meeting a given threshold.

4. The method of claim 1, wherein each data element further includes a distance between a respective mobile device and at least one radio frequency device in the vicinity of the respective mobile device.

5. The method of claim 1, wherein each data element includes an indication of a source of the indoor location of the respective mobile device.

6. The method of claim 1, wherein the list of one or more radio frequency devices in the vicinity of the respective mobile device includes a media access control (MAC) address for each radio frequency device on the list.

7. The method of claim 1, wherein the indoor location of the respective mobile device is based at least in part on a global positioning system location.

8. The method of claim 1, wherein the indoor location of the respective mobile device is based at least in part on a time of flight measurement.

9. The method of claim 1, wherein adding the location for the radio frequency device to a database includes associating the location for the radio frequency device with a media access control (MAC) address for the radio frequency device.

10. A system, comprising:

at least one processor; and

at least one memory storing computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to;

receive a plurality of data elements from a plurality of mobile devices, wherein each data element includes at least;

(i) an indoor location of a respective mobile device, (ii) a list of one or more radio frequency devices in the vicinity of the respective mobile device, and (iii) an indication of a signal strength between each of the one or more radio frequency devices in the vicinity of the respective mobile device and each respective mobile device;

analyze the plurality of data elements to determine a location for a radio frequency device in at least one of the list of radio frequency devices; and

add the location for the radio frequency device to a database.

11. The system of claim 10, wherein each data element further includes an estimated accuracy of the indoor location of a respective mobile device.

12. The system of claim 11, wherein analyzing the plurality of data elements to determine at least one location for a radio frequency device in the list of radio frequency devices includes filtering data elements with an estimated accuracy meeting a given threshold.

13. The system of claim 10, wherein each data element further includes a distance between a respective mobile device and at least one radio frequency device in the vicinity of the respective mobile device.

14. The system of claim 10, wherein each data element includes an indication of a source of the indoor location of the respective mobile device.

15. The system of claim 10, wherein the list of one or more radio frequency devices in the vicinity of the respective mobile device includes a media access control (MAC) address for each radio frequency device on the list.

16. The system of claim 10, wherein the indoor location of the respective mobile device is based at least in part on a global positioning system location.

17. The system of claim 10, wherein the indoor location of the respective mobile device is based at least in part on a time of flight measurement.

18. The system of claim 10, wherein adding the location for the radio frequency device to a database includes associating the location for the radio frequency device with a media access control (MAC) address for the radio frequency device.

19. A non-transitory computer-readable medium comprising instructions, that when executed by at least one processor, cause the at least one processor to:

receive a plurality of data elements from a plurality of mobile devices, wherein each data element includes at least;

(i) an indoor location of a respective mobile device, (ii) a list of one or more radio frequency devices in the vicinity of the respective mobile device, and (iii) an indication of a signal strength between each of the one or more radio frequency devices in the vicinity of the respective mobile device and each respective mobile device;

analyze the plurality of data elements to determine a location for a radio frequency device in the list of radio frequency devices; and

add the location for the radio frequency device to a database.

20. A mobile device, comprising:

at least one processor and memory;

at least one location module configured to determine a location of the mobile device;

an antenna in communication with a transceiver; and

a transceiver, configured to;

identify one or more radio frequency devices in the vicinity of the mobile device and an associated signal strength between the mobile device and each radio frequency device in the vicinity of the mobile device; and

transmit, to a server, the determined location and a data element comprising the identified radio frequency devices and associated signal strengths.
