DigitalSTROM<sup>®</sup>: A centralized PLC topology for home automation and energy management

Abstract

A digitalSTROM <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> system is based on concentrators that reside in the distribution board, act as power-meters for the individual distribution circuits and communicate with individual nodes installed within a home over differently modulated up- and downstream channels. This paper presents the advantages of the digitalSTROM <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> topology, elaborates on the modulation schemes that have been optimized to lend themselves to miniaturized implementation and quantifies the level of interference caused by typical home appliances.
