<p>The method involves producing a sequence of information pulses by generating power using a transmitter. The pulse sequence is fed into an electrical voltage supply network at a feed time point. The pulse sequence is received using a receiver. A signal distribution of the received pulse sequence is analyzed by determining a time point at which power supply is ended by the transmitter or fed power level is varied. Information to be transmitted is assigned as biunique to a difference between the time point and the feed time point.</p>
