Does this work across the polyphase wiring [1] in the house? I'm
guessing not?
Various parts of my house are receiving power from the three different
phases (as provided by the power company), and various power lines in my
household are therefore mutually physically disconnected. Is there a
Homeplug device that would retransmit the ethernet signal from one
phase line to another? Or is the ethernet signal somehow being
transmitted over the single "zero" wire (and how would that even work)?
If neither, that is a serious disadvantage compared to a mesh wifi
network...
Not being an EE, I haven't the slightest idea. US power company
standards are a closed book to me (I live in the UK where I don't think
this would happen for safety reasons, though I could be wrong). In any
case, Homeplug is a widely supported standards so I suggest asking the
manufacturer.
The advantages over mesh networks are cost and (at least in some
configurations) bandwidth.
