OT Powerline Wifi extenders

Fellow Elecrafters,
I am trying to extend the wifi based internet coverage in my property. Alas it has very thick concrete walls with lots of re-bar in them, which is good for the odd earthquake - but not so much for wifi.

I am trying to avoid at all costs of drilling holes in the walls and using ethernet/Fibre/coax etc... With the effect that I havebeen looking at wifi range extending.

I am familiar (and not that impressed with Wifi extenders) but I have been looking at Powerline Extenders - which looks like a clever solution - but one which sound like it should have a QRM-Health warning to all Hams written all over it.

So does anyone use Powerline Wifi extenders ?
If so - any issues ...
Any models you would recommend (or suggest to avoid)

If you would like to read more on this technology the following link should get you started ...

https://en.wikipedia.org/wiki/HomePlug

With this example from TP as to how they can be used

Many thanks

Tim

Re: OT Powerline Wifi extenders

I advise using caution with any Internet-over-power line solutions. Several
years ago there were companies that tried implementing Internet-over-power
line solutions, especially in Texas. Hams fought them tooth and nail (and
won) because these solutions caused so much RFI they left ham radio useless.

Just my two cents' worth. Good luck finding a solution to your challenge.

Re: OT Powerline Wifi extenders

Tim,

Glad to help! Remember this was several years ago. Maybe things have
improved. Do your homework before coming to a conclusion. I just remember
all the hub-bub from a few years ago, when Internet-over-power line first
came up.

Re: OT Powerline Wifi extenders

Look at the data rates too, the last time I looked, it ... was ...
veeeery .... slowwwww.... Then remember that your signal will be
impacting the power lines to some extent.

I use gain antennas where I can, not further than 50' away, which works
through extenders (repeaters). You might want to look at mesh
networking ($$$) as an option.

I run live video through my WiFi repeaters and if you're careful how you
set them up (listen only on 5 gHz, transmit only on 2.4 gHz to the main
router; no SSID broadcast, etc) you can optimize bandwidth, IF the
device(s) can talk on 5 gHz or plug into the extender directly.

I have 'Hardy board' siding, partly concrete; high loss.

Re: OT Powerline Wifi extenders

In reply to this post by a45wg-4

I have a similar situation. I have a pair of powerline extenders, and I
was unable to detect QRM from them on 40-10m. My antenna is not that far
from the building, either.
But from time to time, I lose my connection and have to disconnect and
reconnect to get it back. Sometimes it can be quite annoying! It does
not seem to happen only when I transmit, so I don't think it is picking
up my signal. They are Zyxels.

Re: OT Powerline Wifi extenders

I used them briefly a few years ago for similar reasons, mainly old solid
walls.
As Rick said they were slow!
The other big thing I found (bear in mind it was few years ago) was the fact
that they only worked satisfactorily if on the same circuit. i.e. if the
signal went through the consumer unit the RCCBs attenuated it. I stopped
using the adapters and went for a wired solution using WAPs. There are some
manufacturers that make some WAPS with higher power output which may go
through the walls OK.

Another solution I looked at was TP-Link devices that have the directional
antennas and fit them in the roof spaces pointing downwards through the
timber ceilings etc.

Re: OT Powerline Wifi extenders

In reply to this post by Ian, NV4C

We're mixing what the power companies tried to do sending IP over the
existing power lines to homes, and what the OP is talking about where
you plug a box into an outlet in one room, plug a box into an outlet in
another room and it all happens inside the house.

What he wants is room-to-room in his home, not 50 miles down the power
poles.

Buy the adapters from a reputable source with a good return policy.

They do work, but they very well could raise the RF noise floor.

Hi Tim,

I worked on the Home Power standard from its inception. I Was able to make sure that none of the ham bands were used at all. Thus HomePower (or Powerline as it gets called) should be the perfect solution to your problem.

Memories of the old (circa mid-1990s) plug-in telephone line extenders
that we used with dial-up modems where no tel-line was available. Some
used to work in the 80-meter band. I thought that those devices were
obsolete by now.

Re: OT Powerline Wifi extenders

In reply to this post by a45wg-4

I've been using the TrendNet TPL-40x series of powerline wireless
adapters for a number of years to get my radio computers (upstairs) on
the home network and they work just fine. They're not extremely fast,
but they're certainly fast enough to handle telnet spots, programmed
file backups, and manual file transfers over the network. When there is
activity on the powerline network, I can sometimes see a slight rise in
the noise floor on some bands on my P3. Considering that the antennas
are all very close to the house and that the SteppIR is something like
12 feet directly above the station, this isn't too bad. I keep most of
the routine activity off the powerline path by using a TPL-430 Access
Point device at the end of the house farthest from the antennas and
connecting the computers via a local Wi-Fi net it creates. The master
internet connection comes via the AP but intra-station things like the
GHE control all run over the local Wi-Fi link. Works great for me.

Hi Tim,

I have been setting up my new shack at our remote property. We recently had
a fixed wireless internet connection installed at the house but it was too
far for the wifi signal to reach the shack (~200ft).

I purchased a TP-Link 2-Port Gigabit AV2000 Passthrough Powerline Starter
Kit. So far it is working great with no detectable interference, although at
this time I have only tested on 20 thru 160m. The rural location is very
quiet so I am pretty sure I would know if there was anything nasty being
generated.

BTW - we have three phase power to the house and to the shack. I have tried
the shack end unit on all three phases (whilst leaving the house unit on the
same outlet) and do not notice any change in the internet speed.

Remember that the 2.4 GHz band is UHF radio, and has greater range that
the higher WiFi bands. Some WiFi routers are much better than others.
It's worth studying the reviews online. Antenna location matters. So
does mounting the unit so that it goes through windows rather than
walls, and with line of sight to remote devices. Range can also be
extended by using a WiFi router that allows for an external gain
antenna. I have in my stash a couple of vertical antennas that provide
about 10 dB gain in the horizontal plane.

Re: OT Powerline Wifi extenders

to extend your connection do look at Ubiquiti products.... They are
available worldwide.

I currently employ over 20 devices over a three mile area to get
Ethernet ( broadband) to my remote location.

Your point to point should work with 2 devices for under 100$ each in
the US...

Ubiquiti LiteBeam AC Gen2 LBE-5AC-Gen2 IEEE 802.11ac 450 Mbit/s Wireless

AND THESE ARE VERY FAST.....

The typical source of noise with PoE is from the switching supply -
either connected to a power injector or in some terminal device
(e.g. Router/Modem) with the Ethernet cable acting as the antenna.
Common mode chokes on the Ethernet cable as close to the device as
possible should help but experimentation (and replacing the noisy
power supply) will probably be necessary.

If that is the ONLY source, it might be better to replace it with a
linear supply of suitable current rating. I wouldn't be certain that it
is the only source -- perhaps there's some power conversion happening at
the unit (that is, up on the pole), in which case a choke there would
also be required.

But that doesn't answer the key question I asked Bill -- is the system
noisy or not.

Re: OT Powerline Wifi extenders

some of the ubiquiti poe supplies are noisy... some not.

Since I have 5 poe access points pointing in different directions, i
have two third party power hubs one a 24vdc one a 48 vdc ... both
carry CE markings as does the last Ubiquiti POE ps I used. I do
remember back a while I did have ferrites on both sides of one early
switchers.

Also my HF antennas are at at least 50 feet away , with the tower 140
feet out.

No broadband available for about three miles away. So much for RURAL
BROADBAND.

having to deal with a bit of rfi supression is a small price to pay for
having broadband.

I had great luck with a pair of ubiquity bullets. They were 5.4GHz with built in directional antennas. Great range and speed. My neighbor’s DSL was out a few days so I ziptied one to a propane tank pointing at his house about 150’ away. Not much obstruction though. He said it was much faster than his DSL!

Also had great success with an Engenius AP. It had 2 external antenna ports for diversity. I used the supplied vertical on one to connect near it, and a patch antenna pointed out a window to another building. Nice thing about Engenius is this ran fairly high power, 1W radio worked extremely well with the directional antenna.

I ran 50’ CAT5 with POE to the propane tank where the ubiquity link radio was hung. That’s maybe 80-90’ from my 6m EME array and heard nothing. The CAT5 was due north so not a direction the array was ever pointed and I didn’t go looking for trouble! But I’m pretty quiet, on a good day with some elevation radio is at S0 with preamp on.

No idea how consistent their power adapters are or if they’ve changed suppliers.

The Ubiquity product uses a little power supply which includes the injector. The connections are AC line, and ethernet in/out. So to replace the power supply you’ve got a bit more of a project. Buy them from amazon. Test for noise. Return if necessary and get something else! Much easier than re-engineering a bad design.
