FIELD: physics, communications.
SUBSTANCE: objective is achieved by digital signal injection to electric power network of building over electric bus included in electric junction network of building. Digital signal injection is performed at least in two points of electric bus. Distance between digital signal injection points can be set to maintain required digital data signal power over the whole electric junction network of building, formed on given electric bus (e.g., injection points distributed over the length of electric bus at regular space or by a special formula).
EFFECT: improved reliability and digital data transfer speed and wider facility coverage in building (eg, of flats in residential building) by PLT signal network of sufficient power for digital data transfer.
