Wiring reduction by battery power line communication

Innovative technology for high-speed communication over noisy DC power lines is described. The DC-BUS power line multiplex technology transfers digital information (i.e. car audio, navigation) inside a car, over a single cable that conducts both power (14 V/42 V) and communication. The technology simplifies the installation, reduces harness weight and enables multiple communication channels for mechatronics @10 kbps, telematics @250 kbps and multimedia @1.7 Mbps. Each of the channels serves up to 10 nodes (devices).
