Distortion of the interference field near cables carrying PLC signals

This contribution reports on the conceptual analysis and computer modelling of the electromagnetic field surrounding a domestic power distribution cable network that is also being used for high-frequency telecommunication. It concludes that the field will exhibit widely varying rates of fall-off with distance. It shows that because of the emission from multiple sections of cable, and the complexity of the near-field electromagnetic situation, there are major implications for interference profile and measurement methods. The usual approximation for field vs. distance is invalid in most practical cases.
