ABSTRACT
Reliable communication plays a key role in Smart Grid applications like value-added services, distribution automation, advanced meter reading, load control and remote diagnostics. PLC applications in the frequency range up to 500 kHz, the so-called narrowband PLC (NB-PLC), are becoming more and more popular. NB-PLC is frequently used within Smart Grids due to its relatively large coverage. Unfortunately, the NB power line channel exhibits highly dynamic unpredictable and irreproducible characteristics. Furthermore, it is featured by frequency-selective attenuation and pretty complex noise scenarios. These channel conditions make even low-speed data transmission quite challenging.
