DigitalSTROM®: A centralized PLC topology for home automation and energy management

A digitalSTROM
^®
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
^®
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.
