Abstract

A disruption of power on a network may be detected. A gateway device of the network may transition to a low power mode. The gateway device may determine inactive physical interfaces on the gateway device and shut down the inactive physical interfaces. The gateway device may determine inactive wireless interfaces on the gateway device and shut down the inactive wireless interfaces. The gateway device may determine actively operating physical interfaces on the gateway device and reduce a modulation rate associated with the actively operating physical interfaces for a first time. The gateway device may determine actively operating wireless interfaces on the gateway device and reduce a modulation rate associated with the actively operating wireless interfaces for the first time. The gateway device may shut down the actively operating physical interfaces after the first time. The gateway device may shut down the actively operating wireless interfaces after the first time.

First claim

What is claimed is:

1. A method comprising:
determining, by a gateway device comprising a plurality of components, a disruption of primary power associated with the gateway device;
determining one or more active components of the plurality of components;
causing, based on the determining the one or more active components, a reduction, for a first time period, of a modulation rate associated with the one or more active components; and
causing, based on an expiration of the first time period, backup power to the one or more active components to be removed.

2. The method of claim 1 , further comprising:
determining one or more inactive components of the plurality of components; and
causing, based on the determining the one or more inactive components, backup power to the one or more inactive components to be removed.

3. The method of claim 1 , wherein the backup power is provided by a battery device.

4. The method of claim 2 , wherein the determining the disruption of primary power to the gateway device comprises receiving an indication from a backup battery indicating the disruption of primary power.

5. The method of claim 1 , wherein causing the reduction of the modulation rate associated with the one or more active components comprises causing a reduction in a quantity of spatial streams associated with the one or more active components.

6. The method of claim 5 , wherein the quantity of spatial streams is associated with at least one of a quantity of transmitting antennas or a quantity of receiving antennas associated with the one or more active components.

7. The method of claim 1 , wherein causing the reduction of the modulation rate associated with the one or more active components comprises changing from a first modulation and coding scheme (MCS) to a second MCS that is different from the first MCS.

8. The method of claim 7 , wherein the first MCS comprises at least one of 256 quadrature amplitude modulation (QAM) or 1024-QAM, and wherein the second MCS comprises at least one of binary phase shift keying, quadrature phase shift keying, or 16-QAM.

9. The method of claim 1 , further comprising causing, based on the determining the disruption of primary power, backup power to be provided to at least one voice port or wide area network interface associated with the gateway device.

10. A method comprising:
receiving, at a gateway device comprising a plurality of components, a wireless signal indicating a disruption of primary power associated with the gateway device;
causing, based on the receiving the indication of the disruption of primary power, a reduction, for a first period of time, of a modulation rate associated with one or more of the plurality of components; and
causing, based on determining an expiration of the first period of time, backup power to the one or more of the plurality of components to be removed.

11. The method of claim 10 , wherein the one or more of the plurality of components are first components, further comprising:
determining one or more second components of the plurality of components; and
causing, based on the receiving the indication of the disruption of primary power, the backup power to the one or more second components to be removed.

12. The method of claim 10 , wherein causing the reduction of the modulation rate associated with the one or more components comprises causing a reduction in a quantity of spatial streams associated with the one or more components.

13. The method of claim 12 , wherein the quantity of spatial streams is associated with at least one of a quantity of transmitting antennas or a quantity of receiving antennas associated with the one or more components.

14. The method of claim 10 , wherein causing the reduction of the modulation rate associated with the one or more components comprises changing from a first modulation and coding scheme (MCS) to a second MCS that is different from the first MCS.

15. The method of claim 14 , wherein the first MCS comprises at least one of 256 quadrature amplitude modulation (QAM) or 1024-QAM, and wherein the second MCS comprises at least one of binary phase shift keying, quadrature phase shift keying, or 16-QAM.

16. A method comprising:
determining, by a gateway device comprising a plurality of components, a disruption of primary power associated with the gateway device;
determining one or more active components of the plurality of components;
causing, based on the determining the one or more active components, a reduction, for a first time period, of a modulation rate associated with the one or more active components;
determining one or more inactive components of the plurality of components; and
causing, based on determining the one or more inactive components, backup power to the one or more inactive components to be removed.

17. The method of claim 16 , wherein causing the reduction of the modulation rate associated with the one or more active components comprises causing a reduction in a quantity of spatial streams associated with the one or more active components.

18. The method of claim 17 , wherein the quantity of spatial streams is associated with at least one of a quantity of transmitting antennas or a quantity of receiving antennas associated with the one or more active components.

19. The method of claim 16 , wherein causing the reduction of the modulation rate associated with the one or more active components comprises changing from a first modulation and coding scheme (MCS) to a second MCS that is different from the first MCS.

20. The method of claim 16 , further comprising causing, based on the determining the disruption of primary power, backup power to be provided to at least one voice port or wide area network interface associated with the gateway device.
