Radiated interference of high frequency broadband power line communications

This paper presents a simulation and an empirical study of radiated interference of high frequency broadband power line communications. Utilization of high frequencies for power line communications may cause unwanted radio interference which needs to be treated with caution. The preliminary results obtained in this work show how the components and structures of a power grid segment will contribute to the overall interference radiation when frequencies above 100 MHz are used for power line communication. The results will provide assistance when making more comprehensive measurement campaigns for deciding on the transmission levels for power line communications in UHF and higher frequencies.
