radio ethernet link

I am looking at a radio connection on my small local network, just to the other end of the house and wondering what is the best way to go and what hardware,linux compatible of course is required. A pointer to any docs would be helpfull. I am asking here as I am not sure what I am looking for. Lindsay

Hi Lindsay, The device you're looking for is a wireless bridge. It is a device which connects to your existing wireless network, and you plug your wired devices into it. I have used this device for a project before, and it works well. https://www.jaycar.com.au/wi-fi-bridge-for-smart-tvs-and-media-centres/p/YN8...

if you want to roll your own, have a look at wireless.org.au for usergroups and local communities that will have the resources and links to point you to the right sort of kit... On 3 July 2017 at 18:43, Sean Crosby via luv-main <luv-main@luv.asn.au> wrote:

What's your end goal Ray? If it's simply to make your network, wired and/or wireless, reach the other end of the house younmight consider powerline ethernet (ethernet-over-power) adapters. I'm using them to overcome wireless drop out issues in the kitchen due to the stainless steel splash back killing the signal. Mind you the config software is windows based.

you could use a wireless bridge for that (possibly with an ethernet switch at the remote end). or even a wireless AP if you don't mind the machines at that end connecting via wifi. alternatively, if your house is on stumps rather than a slab, it's easy enough to string a single cat-6 cable from one end of the house to the other. if you have a crimping tool so you can make your own cables, it can be done with only two small & discreet holes in the floor. plug it into a second switch at the other end and you can have multiple machines connected. another alternative, which i've used in the past in rental houses, is to carefully peel back the carpet in the hallway and run a cable under the carpet. and sometimes wooden skirting boards have enough space behind them for an ethernet cable. or run it along a picture-rail to keep it off the floor so it doesn't get tripped over all the time. best of all, though, is to get an electrician or qualified cable layer to put RJ-45 points in every room in the house, all leading back to a central point where you can put your switch and/or file server and/or internet gateway. i.e. as close to your phone/adsl line or NBN or whatever connection as possible. I had this done at home when I got the electricity wiring replaced back in 2000. IIRC it cost about $600 for about 12 points (dual RJ-45 sockets in most rooms, including the bungalow)...but that was a) 17 years ago and b) done as part of a much larger, more expensive rewiring job so would cost more these days. not having to buy a decent wifi bridge or AP would offset some of that expense. craig -- craig sanders <cas@taz.net.au>

Thanks for all the replies, it was a good discusion, I'll likely go for one of craigs suggestions, put a runner carpet down the hall with a couple of cat 5 cables under it, then run it around the skirting board to a RJ45 socket. A likely problem with any radio is I live in a concrete block house, with a suspended floor, all walls including internal are such blocks further more the radio path concerned goes right through the bathroom and kitchen, experience showing such construction is NOT radio friendly. I never really considered ethernet over power as I do a of of medium wave and shortwave listening (Note 1) and ethernet over power is murder RFI wise on the HF bands. Note 1: I currently have 3 recievers, A HRO 60 (I had to make 4 coil box's for it),A Racal RA17C12 and Yaesu FRG7, the first 2 being real outstanding recievers. Lindsay

Lindsay hi
be very wary of running cables under carpet as movement under the cable will rub the insulation off the wires and cause shorts. Repaired a customers PC where this had happened, the MB and PSU were fried. Steve

Just shorting out ethernet shouldn't cause any serious problems though, just failure to connect to the network. Was that PoE or mains cables that caused your customer problems? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

That's correct. Ethernet is very well isolated and current limited. It's almost impossible to damage a computer through the Ethernet jack. Cory

Once the skirting board is off, with a medium breaking bar, or even a cat's paw if the nails come out fairly easily¹, it can be enough to deeply chamfer the lower rear arris with a (power) plane, if a router isn't to hand, to make a nice fat rebate. There will also be much greater risk of splintering tearout in old dry hardwood skirting board, with the router. If it's MDF, then that's no issue, I figure. (I've only dealt with hardwood, though.) The router's handy for curving a groove up to the cutout for the RJ45 socket, but a nice sharp 6mm chisel can do wonders, whacked often enough. Nobody will see the back.

Again many thanks for the replies, a couple of points from the various responses. I have 2 conflicting hobbies computors and MW/SW listening. I live by myself in an isolated house in the hills in NE Victoria, this makes it relatively easy for myself to set up the house for low RFI (Note 1). I have found anything powered by compact switching supples (plug packs) are murder RFI wise, this includes led and any kind of flourecent lights . A desktop computor system is not TO bad if one has high quality power supply case and monitor. Experience among my friends for any kind of radio modem/bridge bit radio/satelite/wifi internet has shown that these are appalling sources of RFI. My skirting boards are screwed on (concrete block walls) so removing these and groving them are no real issue. Also its possible to get rubber protection strips for running cable under carpets, Another way is to run the cable along the outside wall, this being the easier, my networks bridge and the remote station both being on the north wall ofthe house. Note 1: For low rfi reception one needs a GOOD aerial and a radio quite earth ie NOT via the mains earth, its preferable that the radios aerial input circuit is NOT connected to the chassis. A tuned loop is also an excellent low rfi aerial, theses being somewhat easier to match to the HRO and the Racal, both of which expect to see a low impedance resistive aerial. Lindsay

that reminds me of throwing an ethernet cable out the window in Toronto years ago to share my DSL with the dialup neighbours in the flat below. then someone pointed out it was "lightning season" and was I sure I really wanted to do that? :-) fast forward to last week, and I saw what looked to be an earth wire in my ceiling and ran the cat6 cables well below that. dunno if it'll help but thought I may as well.

from your radio antennas I guess you'd know all about lightning risks though... so I'm about to mount a small 'spider' antenna outside for better ADS-B reception. unfortunately I failed to make a 5 or 7-segment coaxial colinear that worked well. I might mount a much larger AIS antenna outside one day too. DVB-T rtl-sdr dongles are so cheap it's hard to resist playing with this stuff :) so do you do anything special for your (presumably large HF) masts/antennas from a lightning point of view? I'm planning a simple RG6 connection of about 5m before it goes into the dongle. the short mast and dome are made out of fibreglass - I figured the less conductive material high in the air the better. cheers, robin ObLinux: the USB rtl-sdr dongles attach to one of 4 small Allwinner Cubie or OrangePi Fedora 25/26 arm/arm64 boxes that I have scattered throughout the house. all on 4.10 or newer mainline kernels.

Here's some guidelines: http://www.arrl.org/lightning-protection https://ham.stackexchange.com/questions/51/how-can-i-protect-equipment-again... A direct lightning strike is a non-trivial problem, as described in the first link on the ARRL site.

A better option of a homebuilt is a broadside array, ie a number (usually 4) dipoles in parrallel, with a backplane behind it, its impedance is reasonable value (70 or so ohms) and its not as critical to use or construct. Details of these can be found on the net no problems.
DVB-T rtl-sdr dongles are so cheap it's hard to resist playing with this stuff :)

NO, one simply disconnects all electronics from the aerial, it NOT being possible for anything like that to service a direct strike. Note: I have MUCH experience on dealing with lightening and its effect on electronics.
I'm planning a simple RG6 connection of about 5m before it goes into the dongle. the short mast and dome are made out of fibreglass - I figured the less conductive material high in the air the better.
