<p>The invention provides differentiation of transmission of two types of dataflow on a common electrical distribution network (1). In particular, the invention provides modulation of useful data signals at high frequencies and modulation of communication management signals at low frequencies. Thus is obtained a high transmission speed for the useful data and a reliable and tolerant communication channel for communication management data. The high frequencies useful data signals are higher than 400KHz and the low frequencies management data signals are lower than 150KHz.</p> |
