A method and a device for communication of data over an electrical distribution network comprise using at a transmission point at least two modems for transmission of time-displaced signals between a neutral point and a respective phase. Reception of said signals is carried out by means of at least two corresponding modems at a reception point. Significantly better performance than in prior art is achieved while the superimposed voltage on a single phase can be used also when the other phases have fallen away. |
