communications (PLC) systems threatened by colluding wireless communication (WLC)
eavesdroppers, which are localized near or far from the transmitter and operate in the same
frequency band. In this regard, we show that PLC and hybrid PLC-WLC channels can be
considered as uncorrelated random processes. In the sequel, we confirm the severity of a
WLC eavesdropper or a group of them located near the transmitter. Also, we show that a …
