Report on electromagnetic compatibility of power line communications

This OMEGA deliverable presents a study of the EMC issues linked to PLC systems, in the context of a frequency bandwidth extension up to 100 MHz. The current status of EMC regulations for PLC is first recalled. An experimental study is then presented for the assessment of the effect of electromagnetic field radiation from an electrical network, in the 30 ­ 100 MHz band. Recommendations are given for the injected PSD levels to be used for future studies within the OMEGA project. From these results, the capacity of the PLC channel is evaluated in terms of outage probability. This analysis shows that an extended bandwidth up to 100 MHz provides capacities in excess of 1 Gbps, while satisfying the current emission limits. Finally, the concept of cognitive EMC is introduced for the mitigation of EMC issues. We experimentally demonstrate that the FM band can successfully be used for PLC transmission without creating harmful interference to radio services.
