Abstract

Representative implementations of devices and techniques provide noise reduction between proximate networks by minimizing interference from nearby network communication. A processing module determines a performance condition of a network and communicates with one or more nodes at a nearby network based on the performance condition of the network.

Claims

1. An apparatus, comprising:

a first transceiver arranged to communicate at least in part via a first network using a first communication medium;

a second transceiver arranged to communicate at least in part via a second network using a second communication medium; and

a processor coupled to the first transceiver and the second transceiver, the processor arranged to determine a level of noise at the first network attributable to the second transceiver and to direct the second transceiver to adjust a power output at the second transceiver based on the level of noise.

2. The apparatus of claim 1, further comprising a memory storage device arranged to store performance data received from at least one of the first transceiver and the second transceiver;

and

wherein the processor analyzes the performance data to determine the level of noise at the first network attributable to the second transceiver.

3. The apparatus of claim 1, wherein the processor is arranged to determine a level of noise at the first network attributable to another node associated with the second network and direct the other node to adjust a power output at the other node based on the level of noise.

4. The apparatus of claim 1, wherein the second transceiver is arranged to send a communication to another transceiver associated with the second network, the communication directing the other transceiver to adjust a power output at the other transceiver based on the level of noise at the first network.

5. The apparatus of claim 1, wherein the processor is arranged to direct the second transceiver to refrain from transmitting for a defined duration.

6. The apparatus of claim 1, wherein the first transceiver comprises a digital subscriber line (xDSL) transceiver.

7. The apparatus of claim 1, wherein the second transceiver comprises a power line carrier (PLC) transceiver.

8. A method, comprising:

determining, at a processing module coupled to a first network and a second network, a level of noise at the first network attributable to a node associated with the second network;

sending a communication from the processing module to the node directing the node to adjust a power output at the node based on the level of noise determined.

9. The method of claim 8, further comprising computing an adjustment to the power output at the node calculated to meet a performance target at the first network.

10. The method of claim 8, further comprising directing the node to adjust the power output at the node to a value resulting in a level of noise at the first network that is less than a preselected threshold.

11. The method of claim 8, further comprising receiving information from the second network;

and

sending a communication from the processing module to the node directing the node to adjust a power output at the node based on a performance target at the second network.

12. The method of claim 8, further comprising determining, at the processing module, a level of noise at the first network attributable to each of a plurality of nodes associated with the second network;

and

sending a communication to each respective node of the plurality of nodes directing the respective node to adjust a power output at the respective node based on a level of noise attributed to the respective node.

13. The method of claim 8, further comprising directing the node to transmit a test communication for noise measurement.

14. The method of claim 13, further comprising receiving a notification from the node, the notification including at least one of a start time and a duration for the test communication.

15. The method of claim 13, further comprising scheduling the test communication to coincide with a preselected type of transmission at the first network.

16. The method of claim 13, further comprising directing another node at the first network to collect performance statistics during the test communication.

17. A system, comprising:

a plurality of transceivers, one or more of the plurality of transceivers communicates via a first communication network and another of the plurality of transceivers communicates via a discrete second communication network, and

a processor coupled to the transceivers, the processor arranged to receive performance statistics from one or more of the plurality of transceivers and to send instructions to the plurality of transceivers based on the received performance statistics.

18. The system of claim 17, wherein the one or more of the plurality of transceivers comprises a digital subscriber line (xDSL) transceiver.

19. The system of claim 17, wherein the processor determines a level of noise at a network attributable to one or more of the plurality of transceivers and directs the one or more of the plurality of transceivers to adjust a power output at the one or more of the plurality of transceivers based on the level of noise.

20. The system of claim 17, wherein at least one of the plurality of transceivers is arranged to communicate via multicarrier symbols including tones or sub-channels, the tones or sub-channels having data bits modulated thereon.
