Point to Point Wireless

[MatthewL]

Has anyone with success implemented a point to point wireless link over say a 9 mile distance?

 

If so any hints and tips for it? I think the height of the dish is going to be my issue due to the terrain but but anything else I should watch out for?

Linus Tech Tips?

Beaten to it, was about to say Linus managed a damn-near gigabit link that distance with Ubiquiti gear

Funny enough was watching that same video at the weekend. Other than siting the pole with the dish on and configuring both dishes is it as simple as that? Nothing else to watch out for?

All you need to make sure that you have is a full line of site. And if you can get unifi gear then you have all the tools you need in their software.

We use one of these for a 160Gbps (I know it's not 1Gbps like you asked but we've had it a few years now and they may have a newer model at that speed):

 

 

It's not line of site so things like a tree being in the way hasn't hindered our installation! The model we have goes up to 31miles although I think you'd need a bloody good pair of binoculars at both end to get it lined up the best you can!

Loads of Ubiquiti point to point and mesh stuff on this youtubes channel.

+1 for Ubiquiti gear, we use a lot smaller gear here (under 500 meters) but simple to setup and is basically the same as the higher end gear just less powerful.

 

All you need is line of sight for PTP gear, also make sure there isn't anything that moves into line of sight, seen problems in the past where the PTP had a train track in between, lost a few seconds everything a train went past!

 

Edit: Turns out our PTP is slight overkill for the distance! We use the AC-Gen2: https://www.ubnt.com/airmax/nanobeam-ac-gen2/

 

Which can apparently do 15km! No wonder they do 500m so well...

Ubiquiti have this handy mapping tool, which suggests that I would be look at between 40 and 50 m height for the two dishes. One been in a village in a dip which doesn't help.

 

Due to the kit required I think this little project is out the window till a time with more money. To have a dish that high would require some pole which is another problem.

+1 for the AC-Gen2. I've got a link between buildings (two sides of a main road) and the link distance is 82m with a speed of 650mb and it's never missed a beat. You would struggle to know you weren't on the end of 1gb fibre!!

 

Next project for me is a 860m link up to the sports pavilion to enable wifi at the playing fields

How does the channel width work please?

[MatthewL]

Pass, its all still quite new to me, never done anything on this scale before, only ever linked two Belkin AP's together as a bridge years ago from a wireless link point of view.

How does the channel width work please?

 

In what sense?

 

Simply, you need to balance the channel width with the signal quality and range you need from the particular radios and frequencies you're using.

[AJWhite1970]

On the AC-Gen2 if you manually set the distance the two dishes are apart by putting in the two long/lat coordinates it automagically sets the channel width and signal power accordingly which is a good starting point. Then you use the alignment tools in the Air OS to tweak to find stable settings.

[MatthewL]

Thanks for that, that is interesting to know.

I see. So you sacrifice bandwidth to do a longer distance connection?
