Abstract
An apparatus is disclosed where a Powerline interface is used to transmit data into the powerline grid network, where the powerline interface is pulling the required transmit energy from the power grid network, where the powerline interface is transmitting data using standard narrow band modulation such as ASK, FSK, S-FSK, where the transmitted data are passed on to the powerline interface by the use of an “Input signal” adapation stage, where an error calculation and a comparison to a “Triangle” signal is performed to create a command signal used to enable the transmission of data by providing enough voltage to polarize the Transistor (i.e: MOS FET) used in the powerline path.
