Abstract:
1. A device for communicating data signals with a power line, the device comprising: a transformer having a magnetic core, a first winding, and a second winding; wherein said first and second winding each have a first end and a second end; wherein said second winding is configured to be communicatively coupled to a communications device; wherein said first end of said first winding is configured to be communicatively coupled to the power line at a first location; wherein said second end of said first winding is configured to be communicatively coupled to the power line at a second location; wherein said first location and said second location are separated by a first distance that is greater than five percent of a wavelength of a carrier frequency used to communicate the data signals; and wherein data signals arriving at the first location via a first path that includes said first end of said first winding and via a second path that includes said second end of said first winding and the power line are additive for one or more carrier frequencies used to communicate the data signals.
