The usage of power line communications, PLC over the low-voltage electrical power supply networks gives an alternative for the telecommunication access. Initially power lines were used for controlling appliances, however with the recent technology advancements the power lines are now able to compete successfully with other relatively stable home networking technologies like wireless and phone line. Despite the advantages that PLC can offer, it is associated with the major cause of harmful interference to other users of the wireless spectrum. PLC risks not living up to its full development and success unless proper standards and regulations are developed globally. The objective of this thesis is the analysis of problems related to electromagnetic compatibility of broadband power line communications. The study comprises both theoretical and experimental analysis. The experimental work was conducted in the form of field measurements, performed in real power line communication network. For the theoretical work, PLC networks were modeled and simulated with the Numerical Electromagnetics Code (NEC).
