I use powerline ethernet to connect streaming devices back to upstairs
partly because I only have one Cat5 cable running the length of the
house. It works pretty well but you will get various radio Hams along
shortly telling you that this technology is the spawn of the devil.

FWIW I can't see any effect on my RF scanner with or without it. A very
badly designed phone picks up mains hum if held really close to a node.

BTW A Wifi repeater might more accurately do what you say you want.

Provided that they are all on the same ring main it works very well.

I'd recommend TP link or similar. BT badged ones likely to be
overpriced. I think these are the descendents of mine:

I think it is worth reading about these claims, and then making up your
own mind. If somebody does indeed come knocking on your door
complaining, you will know what he/she is talking about. If nothing
else, reading the anti-Homeplug website is amusing for the apparent
histrionics of the writers, if only I could find it. Maybe they have
taken it down.

Also, avoid any extensions with surge suppressors, they can block the
signals. Best to find a wall socket.

Just bung a switch on the end of the cable for the multiple remote
devices. Unless you are streaming lots of things at hefty bit rates
the 100 Mbps "bottle neck" of the cable won't be a problem.

The OP isn't clear if the "remote" end will be in the shed. If it is
the shed supply should not be directly connected to any of the house
rings. It should be a seperate supply from the CU. At the very least
it needs to have a RCD in the circuit, which may degrade the HomePlug
signals.

Gigabit switches are dirt cheap nowadays and the Cat5 will probably
work at 1000Mb/s quite happily.

I was planning to put the remote in the dining room (with window

That isn't always a problem.

I have a couple of powerline networking devices talking to each other
quite happily despite being on different rings - there's even a second,
daisy-chained, RCD'd consumer unit in the way.

I had a similar setup, without the daisy-chain, and it worked, as
well. What blocked the Powerline signal was using an extension with
surge suppression. As was warned about in the blurb that came with it.

The electrical route between mine is:

That is through three CUs, It just about works...

I'd still need a WAP pulling 5 W (for example) at the back end of the
house.

Most routers suffer the problem of only having one radio for the wifi
side - hence they halve throughput when acting as a repeater. You need
mimo kit to get round that.

Maybe so, depending on the kind of repeater. I guess those keep

I've read that some (many?) wifi extenders (maybe not true

Theres not that much spectrum located to Amateur radio use and that what
is, is used in the main quite well.

Theres quite a bit spare but it tends to be on frequencies that are not
that much use for mobile phones and such applications.

UK VHF Low band 30 to 80 MHz comes to mind and areas around 136 to 155
odd.


The military have quite a bit around 230 to the upper 300's odd..

Most of them are, but you do need to know something about
antennas to know what the difference between those and normal
TV antennas and CB radio antennas are.

Maybe so, depending on the kind of repeater. I guess those keep
things simple by using the same SSID, whereas the kind of kit I've
been looking at would provide a different one --- is that right?

I did initially set the repeater up using the same SSID and it did work
fine like that for about 6 months but then I found that some of the
devices used by the neighbours didn’t use the higher power point
properly so it was better to have a different SSID to fix that problem.

I've read that some (many?) wifi extenders (maybe not true
"repeaters"?) halve the overall wifi bandwidth available from the main
WAP because they use it up relaying onward.

You have that backwards. The repeaters that receive and
transmit wifi have to halve the wifi bandwidth because
they can't receive and transmit at the same time unless
they do that on different bands.

The extenders which have a cat5 cable to them don’t have
that problem.

Yes, I allow two of my neighbours to use my wifi that
way over a much bigger distance than your back garden.

I use a Medion P85019 (MD 86977) that Aldi sells periodically
and have it powered on a long extension cord from my house
with it under a big plastic bucket half way down the back yard
of the neighbour's yard that back onto mine. I use it in wifi
repeater mode which halves the thruput, but it can also be
used in access point mode with a CAT5 cable to my router
which would allow it to run at full speed. I don’t do that because
there is more risk of a lightning strike with that approach
and they don’t care about the lower speed they get.

(One of my friends in the US uses "powerline" (network over

That approach can be more tricky if there
is more than one phase in the house.

H obviously does not have close neighbours trying to use short wave radios

These devices, in many peoples oppinions should be banned in their current
form. After all mainswiring is not very good at lossless movement of rf
signals so the devices tend to use a high power to get it through, and in
so doing radiate basically from medium wave op to 30 mhz of nasty spiky
hash, ticking noises and buzzes all over the close by neighbourhood.

We receive FM quite happily. One radio is right underneath one of the
powerline units, another is pretty much right above the other.

We don't have a DAB receiver, yet, but borrowed a neighbour's recently to
check if it would work here - and got an excellent signal.
