For the use of the mains networks as high speed data path for Internet, voice and data services carrier frequencies within the range from 500 kHz up to 20 MHz must be considered. The development of suitable communication systems and the planning of power line communication networks requires measurement-based models of the transfer characteristics of the(More)
Opposite to many other communication channels the powerline channel does not represent an additive white Gaussian noise (AWGN) environment; in the frequency range from some hundred kilohertz up to 20 MHz it is mostly dominated by narrow-band interference and impulsive noise. After a basic classification of the different types of noise the properties of(More)
Advanced Metering Infrastructures require reliable communication links. This paper proposes a protocol stack for smart metering based on the parameters of a robust low-speed PLC physical layer. The protocol stack under consideration implements IPv6 on top of a contention-free media access control sub-layer, thereby allowing for maximum flexibility.(More)
In Lithium-ion battery systems used for automotive traction applications a communication network is required for monitoring and control functions. We consider the power line communication (PLC) as a good alternative to data transmission buses used up to date in Lithium-ion battery systems, with the main scope consisting in reducing the cable harness and(More)
Test and verification of the physical layer of power line communication systems are very difficult to accomplish, because the mains grid exhibits stochastic and time variant behavior. In this paper, we propose a channel emulator that allows for emulating a freely configurable PLC channel scenario in the frequency range between 9 kHz and 500 kHz. The(More)
Exact knowledge of the impedance is a key aspect for power line modem development as well as for modeling channel transfer characteristics of power distribution networks used for low-frequency power line communications (PLC). Therefor we present an approach for precise impedance determination at the low-voltage grid and results we obtained from a(More)
