Patent ID: 7148788

Claim:
A method for transmitting radio-frequency signals on low-voltage networks, in which electrical power is provided from a central power supply by busbars and is passed via at least one of outgoer cables and distribution busbars to loads, having input points for feeding in signals in kilohertz and megahertz bands and outgoer points for tapping off signals and power which are transmitted on a conductor system, comprising: feeding the signals in at an end of the outgoer cables and distribution busbars which is opposite mains-frequency power feed to improve a transmission response; and connecting the outgoer cables and distribution busbars which carry radio-frequency signals for signal conditioning, at an end which is opposite the power feed by a PLC coupling cable, which carries radio-frequency signals, allowing data to be interchanged between modems on various outgoer cables and distribution busbars.
