Patent ID: 8710695

Claim:
A plug link device, comprising: a first prong; a first electrical line coupled to the first prong; a second prong; a second electrical line coupled to the second prong; and a first PLC interface coupled to the first electrical line, the first PLC interface configured to: receive, from the first electrical line, a PLC signal in an Orthogonal Frequency Division Multiplexing (OFDM) format; and transform the PLC signal into a layer 2 frame format; a capacitor coupled to the first PLC interface, the capacitor operable to receive the PLC signal in the layer 2 frame format; and a second PLC interface coupled to the capacitor and the second electrical line, the second PLC interface operable to receive the PLC signal in the layer 2 frame format from the capacitor and return the PLC signal to the OFDM format before transmitting the PLC signal to the second electrical line, and wherein transforming the PLC signal from the OFDM format to the layer 2 frame format or communication by the capacitor strengthens the PLC signal such that the PLC signal that is received from the second PLC interface at the second electrical line is stronger than the PLC signal that is received by the first PLC interface from the first electrical line.
