Abstract

Systems and methods for communicating over a power line are configured to substantially simultaneously communicate over a plurality of wideband frequency ranges. Signals may be communicated two or from a communication node at two different frequencies simultaneously. These signals may be exchanged with different nodes and/or include independent data. In some embodiments, some of the wideband frequency ranges are above 30 MHz.

Claims

1. A communication network comprising:

a first communication node configured to communicate using a first wideband frequency range, at least part of the first wideband frequency range being below 30 MHz;

a second communication node configured to communicate using a second wideband frequency range separate from the first wideband frequency range, at least part of the second wideband frequency range being above 30 MHz; and

a third communication node configured to simultaneously and independently receive communication from the first communication node over a power line using the first wideband frequency range and from the second communication node over the power line using the second wideband frequency range, wherein the third communication node is further configured to communicate with the first communication node using the second wide band frequency range.

2. The communication network of claim 1, wherein the first communication node and the third communication node are both configured to communicate using a third wideband frequency range separate from the first wideband frequency range and the second wideband frequency range.

3. The communication network of claim 1, wherein the third communication node is further configured to determine which wideband frequency range(s) to use in communicating with the first communication node and the second communication node.

4. The communication network of claim 3, wherein the third communication node is configured to determine a standard to use when communicating using the first wideband frequency range and to determine a different standard to use when communicating using the second wideband frequency range.

5. The communication network of claim 1, wherein the third communication node comprises an analog frequency filter configured to separate signals within the first wideband frequency range from signals within the second wideband frequency range.

6. The communication network of claim 5, wherein the analog frequency filter is configured to convey signals within the first wideband frequency to first processing electronics and signals within the second wideband frequency to second processing electronics.

7. The communication network of claim 1, wherein the third communication node is further configured to automatically detect the first communication node and the second communication node using the first wideband frequency range and the second wideband frequency range, respectively.

8. The communication network of claim 1, wherein the first wideband frequency range and the second wideband frequency range are each at least 5 MHz wide.
