| Abstract(in English) | In Japan, in-house broadband power line communications (PLC) are regulated only in terms of the common-mode current (CMI) measured using the ISN (LCL=16dB, DMZ=100Ω, CMZ=25Ω). However it is scientifically not yet verified that such a regulation could control the radiated electric field (REF) at the distance of 10m below the ambient noise level. We have investigated CMI and REF caused by the various commercial PLCs in residential environment and found that; REF could exceed the ambient by more than 30dB even if CMI satisfies the regulation, CMI could exceed the legal limit by more than 15dB even if the outlet has high LCL, no causality is found between CMI or LCL and REF, CMI along the power line could exceed that injected from the modem by more than 20dB, and, the ambient noise below 15MHz is 10dB smaller than the value assumed for the regulation. It is concluded that the regulation has serious flaw and could not control the REF below the ambient level. |
