LED Lighting and the Impact on the PLC Channel

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 2, Page # 933–941, 2021; DOI: 10.25046/aj0602106
Abstract:

Light Emitting Diode (LED) lamps are used as a replacement of “old-fashioned” or incandescent lighting sources, as they reduce the amount of energy consumed. As a side-effect of more efficient energy usage they produce electrical noise. This noise reduces the efficiency of information signal transfer when Power Line Communications (PLC) are used. This study focuses…
