Abstract

A system may comprise a sensor device. The sensor device may be configured to determine a received signal strength indicator (RSSI) of a signal received from another device. The sensor device may be configured to determine, based on the RSSI and a sensitivity threshold, a transmission power level. The sensor device may be configured to send a second signal using the determined transmission power level.

Claims

1. A method comprising:

determining a received signal strength indicator (RSSI) of a first signal from a first device to a second device;

determining, based on the RSSI exceeding a sensitivity threshold of the second device, a transmission power level; and

causing sending of a second signal using the transmission power level.

2. The method of claim 1, wherein the determining the RSSI of the first signal comprises determining the RSSI of the first signal by a third device.

3. The method of claim 1, wherein the determining the transmission power level comprises determining the transmission power level by a third device.

4. The method of claim 1, wherein the causing sending of the second signal comprises causing, by a third device, the sending of the second signal.

5. The method of claim 1, wherein the determining the RSSI of the first signal comprises determining the RSSI of the first signal by the second device.

6. The method of claim 1, wherein the determining the transmission power level comprises determining the transmission power level by the second device.

7. The method of claim 1, wherein the causing sending of the second signal comprises causing, by the second device, the sending of the second signal.

8. The method of claim 1, wherein the sensitivity threshold of the second device comprises a minimum signal strength that the second device is configured to receive.

9. The method of claim 1, wherein the causing the sending of the second signal comprises sending, to at least one of the first device or the second device, an indication to modify a transmission power of the at least one of the first device or the second device.

10. A first device comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the first device to;

determine a received signal strength indicator (RSSI) of a first signal from a second device to a third device;

determine, based on the RSSI exceeding a sensitivity threshold of the third device, a transmission power level; and

cause sending of a second signal using the transmission power level.

11. The first device of claim 10, wherein the instructions, that when executed, cause the first device to cause the sending of the second signal comprise instructions that cause the first device to cause the sending of the second signal to a fourth device.

12. The first device of claim 10, wherein the instructions that, when executed, cause the first device to cause the sending of the second signal comprise instructions that cause the first device to send the second signal using the transmission power level.

13. The first device of claim 10, wherein the instructions, that when executed, cause the first device to determine the RSSI of the first signal comprise instructions that cause the first device to receive an indication of the RSSI of the first signal.

14. The first device of claim 10, wherein the instructions, that when executed, cause the first device to determine the RSSI of the first signal comprise instructions that cause the first device to:

receive, by the first device, the first signal; and

determine, based on the received first signal, the RSSI of the first signal.

15. The first device of claim 10, wherein the instructions, that when executed, cause the first device to cause the sending of the second signal comprise instructions that cause the first device to send, to at least one of the second device or the third device, an indication to send the second signal using the transmission power level.

16. A non-transitory computer-readable medium storing instructions that, when executed, cause:

determining a received signal strength indicator (RSSI) of a first signal from a first device to a second device;

determining, based on the RSSI exceeding a sensitivity threshold of the second device, a transmission power level; and

causing sending of a second signal using the transmission power level.

17. The non-transitory computer-readable medium of claim 16, wherein the causing sending of the second signal comprises causing sending of the second signal by a transmitter of at least one of the first device or the second device.

18. The non-transitory computer-readable medium of claim 16, wherein at least one of the first device or the second device comprises a premises device.

19. The non-transitory computer-readable medium of claim 16, wherein the sensitivity threshold of the first device comprises a minimum signal strength that the second device is configured to receive plus a buffer amount.

20. The non-transitory computer-readable medium of claim 16, wherein the causing sending of the second signal using the transmission power level comprises causing sending, to at least one of the first device or the second device, of data configured to modify a transmission power of the at least one of the first device or the second device.

21. A method comprising:

determining a received signal strength indicator (RSSI) of a first signal received by a first device from a second device;

determining, based on the RSSI exceeding a sensitivity threshold of the first device, a transmission power level; and

causing the second device to send a second signal using the transmission power level.

22. The method of claim 21, wherein the causing the second device to send the second signal using the transmission power level comprises sending, to a third device, information configured to cause the second device to send the second signal using the transmission power level.

23. The method of claim 21, wherein the causing the second device to send the second signal using the transmission power level comprises sending, to the second device, an indication of the transmission power level.

24. The method of claim 21, wherein the causing the second device to send the second signal using the transmission power level comprises sending, to the second device, information configured to cause the second device to send the second signal using the transmission power level.

25. A first device comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the first device to;

determine a received signal strength indicator (RSSI) of a first signal received by the first device from a second device;

determine, based on the RSSI exceeding a sensitivity threshold of the first device, a transmission power level; and

cause the second device to send a second signal using the transmission power level.

26. The first device of claim 25, wherein the instructions, that when executed, cause the first device to cause the second device to send the second signal using the transmission power level comprise instructions that cause the first device to send, to a third device, an indication to cause the send device to send the second signal using the transmission power level.

27. The first device of claim 25, wherein the instructions, that when executed, cause the first device to cause the second device to send the second signal using the transmission power level comprise instructions that cause the first device to send, to the second device, a third signal using the transmission power level.
