Abstract (in Japanese) (See Japanese page) 
(in English) The radiated electric field (REF) of the in-house broadband power line communications (PLC) in Japan is supposed to be below the ambient noise level, but actually exceeds it by more than 30dB. We have measured the REF, common mode current (CMI) and differential mode current (DMI) of the PLC modem and service line and found that the DMI is 40dB larger than the CMI and the major cause of the REF. In-house to service line DMI leakage is 0 to -30dB and almost 100% converted to the CMI, which exceeds that of the modem and contributes to the REF. The blocking filter is required. The REF or DMI must be regulated.
