Patent ID: 8724526

Claim:
A system for wirelessly transmitting a communication signal between power delivery lines comprising: a Digital Signal Processing (DSP) modulator having an output coupled to an input of a Frequency Modulator (FM) device, the DSP modulator outputting a DSP signal to the FM device, the FM device receiving the DSP signal and frequency modulating the DSP signal to generate a combined FM-DSP signal; a transmitter which receives the FM-DSP signal from the FM device and outputs the FM-DSP signal at a radio frequency; a first power delivery line which receives the FM-DSP signal from the transmitter and radiates the FM-DSP signal from a conductor of the first power delivery line; a second power delivery line which wirelessly receives, by a conductor of the second power delivery line, the FM-DSP signal radiated from the first power delivery line, and a receiver connected to the second power delivery line which receives the FM-DSP signal from the second power delivery line via a coupler; said coupler being either a capacitive or a resin/dielectric-filled type of coupler which matches the characteristic impedance of the second power delivery line to the characteristic impedance of the receiver.
