1. A method for transmitting data using a differential voltage, frequency offset, OOK transmission, the method comprising:

  • receiving a data signal from a data source device;

    providing a base frequency carrier;

    controlling states of the base frequency carrier, the carrier states including an on state and an off state;

    transmitting the data signal, using the base frequency carrier, to a power line via one of a pair of couplers, the pair of couplers corresponding to an active power line state and a passive power line state;

    receiving the transmitted data signal from the power line by one of a pair of decouplers, the pair of decouplers corresponding to the active power line state and the passive power line state; and

    sending the data signal to a data receiving device.
