Comparisons of Indoor PLC Emissions Measurement Results and Regulation Standards

Measurements of emissions are carried out over a low voltage (LV) indoor power line system in the frequency range of 1 MHz - 30 MHz. In the measurement setups, efforts are made to comply with the setup specified in the existing standards. The results obtained are compared to the current regulations/proposed limits. It is shown that the measured emissions do not currently meet all the specified limits. It is also suggested that future power line communications systems will have to transmit at lower radiation power levels in order to meet those limits
