Abstract:
1. A method of enhancing communication signals in a communications system ( 1 ) tat uses power lines (L 1 ) as a communication pathway, wherein communication signals are subject to attenuation as they travel along the power lines over a distance, and wherein the communication signals transmitted over the power lines in a transmission direction are repeated in order to keep the communication signals from being reduced below a pre-defined level, the power lines (L 1 ) comprising a plurality of phase lines (P 1 , P 2 , P 1 , P 2 , P 3 ) disposed alongside of each other to carry alternating current electrical power in different phases relative to each other, said method comprising the steps of: transmitting the communication signals (S receiving the communication signals (S providing first signals ( receiving the first signals (
