Hello mick.crane,
Is there not some system that runs ethernet over the mains wiring or
did I misunderstand it.
Yes, there is. I believe you're thinking of powerline adaptors. They
do require everything be on the same circuit, however.
I have a powerline adapter (Devolo units). There's no such restriction,
as far as I know. My powerline transmitter and receiver are certainly
on different circuits.
The way electrical wiring is done in the UK often means separate
floors are on different circuits, and in larger properties, each
floor might be on two (or more) circuits, making it difficult, at
best, to get the whole building networked this way. And that's
assuming ring circuits, if everything is on a radial, you're stymied.
Most houses in the UK are wired to a single phase, so everything is
connected together at the consumer unit and powerline works just fine.
If you have a specific problem, then there are DIN rail powerline units
designed specifically to be mounted in the CU to spread the signal
better over ALL the circuits.
Yes and no. Most houses in the US are wired 'single phase as well...
but they tap off 240vac, and then split that to two 120v 'legs'. As
long as all the powerline ethernet devices are plugged into circuits on
the same 120v leg, they'll talk together just fine. If they are spread
across both legs... not so much. There's literally a coil of the xfmr up
on the pole (or padmount) between those two sections, and it blocks HF
comm waves pretty effectively.
Although... in theory... i.e. it occurs to me but i haven't tried it
personally... you *might* be able to have plugs in both 'legs'
connected to a switch, and be able to bridge them that way. Might be
some overarching electrical/grounding considerations worth thinking
about further, though. More likely the immediate 'problem' is finding
two circuits conveniently close to one another physically, yet on the
separate legs of the mains. Not extremely likely, and it'd probably be
far easier to pursue other solutions.
