Abstract

Methods, systems, and apparatuses for managing a wireless network are described herein. A wireless network may include a gateway device, an access point, and a group of client devices. An analytics engine may determine a signal characteristic data for a client device, which may indicate network telemetry data for each of the client devices or associated locations during a time period. The analytics engine may utilize a trained classifier to determine that a signal characteristic indicated by the signal characteristic data for a client device satisfies a threshold.

First claim

What is claimed is:

1. A method, comprising:
receiving data associated with one or more sensors located at an entry point or exit point of a premises;
determining, based on the data associated with the one or more sensors, signal characteristic data associated with one or more client devices at a time at which the one or more client devices are proximate to the one or more sensors;
determining, based on the signal characteristic data associated with the one or more client devices and the data associated with the one or more sensors, an authorized client device of the one or more client devices; and
providing a network service to the authorized client device.

2. The method of claim 1 , wherein the data associated with the one or more sensors located at the entry point or the exit point of the premises comprises an indication that a door or window has been opened or broken.

3. The method of claim 1 , wherein the signal characteristic data associated with the one or more client devices comprises at least one of: a probe request, a transmission power, a received signal strength indicator (RSSI), a signal-to-noise ratio, a time of flight, a frequency, an amplitude, a data traffic characteristic, a MAC address, or an interference metric.

4. The method of claim 1 , further comprising:
determining, based on the signal characteristic data associated with the one or more client devices, a signal characteristic data profile associated with the one or more client devices; and
comparing, the signal characteristic data profile associated with the one or more client devices to the signal characteristic data associated with the one or more client devices.

5. The method of claim 1 , further comprising:
determining, based on the signal characteristic data associated with the authorized client device, a user profile associated with the authorized client device; and
causing, based on the user profile associated with the authorized client device, an action.

6. The method of claim 5 , wherein the action comprises at least one of: sending a message, triggering an alarm, determining a lighting setting, or determining an audio setting.

7. The method of claim 6 , wherein sending the message comprises:
sending, to a computing device, the message, wherein the message comprises at least one of: the signal characteristic data associated with the one or more client devices, a position of the one or more client devices, an identifier associated with the one or more client devices, or an option associated with the one or more client devices.

8. A method comprising:
receiving data associated with one or more sensors located at an entry point or an exit point of a premises indicating entry into the premises;
determining, based on the data associated with the one or more sensors, signal characteristic data associated with one or more client devices at a time at which the one or more client devices are proximate the one or more sensors;
determining, based on the signal characteristic data associated with the one or more client devices and the data associated with the one or more sensors, a position of an unauthorized client device of the one or more client devices; and
causing, based the position of the unauthorized client device, a security action.

9. The method of claim 8 , wherein the data associated with the one or more sensors located at the entry point or the exit point of the premises comprises an indication that a door or window has been opened or broken.

10. The method of claim 8 , wherein the one or more sensors comprise at least one of a motion detector, a thermal sensor, a window alarm, a door alarm, a proximity sensor, or a camera.

11. The method of claim 8 , wherein the one or more client devices comprises at least one of a computer, laptop, mobile phone, or tablet.

12. The method of claim 8 , wherein the signal characteristic data associated with the one or more client devices comprises at least one of a received signal strength indicator, transmission power, data traffic characteristic, or probe request.

13. The method of claim 8 , wherein determining the unauthorized client device comprises:
determining, based on the signal characteristic data associated with the one or more client devices, a signal characteristic data profile associated with the one or more client devices; and
comparing, the signal characteristic data profile associated with the one or more client devices to the signal characteristic data associated with the one or more client devices.

14. The method of claim 8 , wherein the security action comprises a home security action or a network security action.

15. A method comprising:
receiving data associated with one or more sensors located at an entry point or an exit point of a premises;
determining, based on the data associated with the one or more sensors, signal characteristic data associated with one or more client devices at a time at which the one or more client devices are proximate the one or more sensors;
determining, based on the signal characteristic data associated with the one or more client devices, a position of the one or more client devices relative to the entry point or the exit point of the premises; and
determining, based on the signal characteristic data associated with the one or more client devices, a position of the one or more client devices relative to one or more access points.

16. The method of claim 15 , wherein the one or more sensors comprise at least one of a motion detector, a thermal sensor, a window alarm, a door alarm, a proximity sensor, or a camera.

17. The method of claim 15 , wherein the data associated with the one or more sensors located at the entry point or the exit point of the premises comprises an indication that a door or window has been opened or broken.

18. The method of claim 15 , wherein the signal characteristic data associated with the one or more client devices comprises at least one of: a probe request, a transmission power, a received signal strength indicator (RSSI), a signal-to-noise ratio, a time of flight, a frequency, an amplitude, a data traffic characteristic, a MAC address, or an interference metric.

19. The method of claim 15 , further comprising:
determining, based on the signal characteristic data associated with the one or more client devices, an authorized client device or an unauthorized client device.

20. The method of claim 15 , further comprising:
causing, based on the signal characteristic data associated with the one or more client devices and the position of the one or more client devices relative to the one or more access points, an action, wherein the action comprises at least one of a user setting or security action.

21. The method of claim 1 , further comprising:
determining, based on the signal characteristic data associated with the one or more client devices, a boundary of the premises.

22. The method of claim 8 , further comprising:
determining, based on the signal characteristic data associated with the one or more client devices, a boundary of the premises.

23. The method of claim 15 , further comprising:
determining, based on the position of the one or more client devices relative to the entry point or the exit point of the premises and the position of the one or more client devices relative to the one or more access points, a boundary of the premises.
