As a former tower tech and WISP guy, set the Tx to -4db and auto adjust power off. You'll get a better alignment that way, also some freaking HOT signals between the two lol. I'd also recommend getting a set of Cambium POE surge protectors. We use them on towers quite a bit and they have held up to literally lightning strikes over and over. Highly recommended. Suggestion #2: During high winds them mounts ain't gonna hold 😂 you need a 6x6ft full of bricks with the mast in the center Suggestion #3: Your LOS may be getting cut off by the parapet a bit, raise them about a foot or so higher and you'll get a significantly better quality in TX/RX.

[@WiFiBERnet]

Yes do this everything 12GaugeNick said is correct! Horizontal and Vertical Polarization so half your wireless Frequency is getting cut off by the parapet it looks like, which will explain the weirdness in speeds in one direction vs the other! the size of those satellites might be too big as well meaning its overkill for the distance used. Its like standing next to eachother talking with megaphones. You'll blow out your ears so to speak! -50 to -60 dbm is what you want for best results both directions =] -50dbm is probably the best when it downpours as rain will affect 60GHz and its a very small parabola effect and fresnel zone meaning they have to be perfectly lined up. Use Lasers! it makes it much easier to align at that distance too. Make sure your WiFi signal on 60GHz is clean too both HQ and Remote (im sure it is but make sure.) I've shot AirFiber over 42Miles and its incredible to say the least! AF 5HDX (with Monster Antennas) [EF ELEMENTS ULTRAHORNS are probably the best PtP] Also make sure the NTP servers are set correctly Wireless is heavily time correct dependent. I'm sure the GPS Geosync will also ensure this but for maximum efficiency do it for the best internets.

[@qboy2terafirma]

Also check they are level as polarized signals present as interference if they don’t both align. Better again move to Cambium gear e.g. cnWave would do a 3 way bridge between your buildings using 60GHz or licensed links using eband would be able to do 40Gbps each with gear like Aviat that doesn’t cost what you might think.

[@friesm2000]

Suggestion #4: Should have just run a cable between the buildings over the parking lot just like they do with power lines, don't have to worry about any trucks hitting it, since it's high enough...... But yes it would void the reason for the video with dishes, but would work better though

[@WiFiBERnet]

@@friesm2000 I think it might be over 100meters though as the cable runs and would technically probably break the TOS for their offices. Unless doing Fiber which would be equally as expensive if not more so and labor intensive to be built to code with permits to not break TOS.

[@markerichannelly]

The speed jumping to 1Gbit and then higher is probably the dishes jumping between 5GHz and 60Ghz. VHT160 5Ghz is about 800-950mbit. Probably look at getting both of the dishes mounted higher, likely the fresnel zone is getting cut off being so low to the roof.

[@craigedgar2828]

Raising the dish will also help prevent distortion from snow in the winter.

[@Darkk6969]

Yep, I kept telling myself the dishes needs to be raised higher. Hopefully they will see this and try again.

[@littlewicky1]

From the spec sheet, the 60XG doesn't support VHT160 only up to 80. The 5Ghz radios are only for backup, in case 60Ghz radios have trouble. My guess is on a flaky termination of the cables runs. The radios are reporting almost 6 gigs of capacity, so the problem doesn't seem to be them.

[@Folkstorm87]

they need to be higher, or at least on the edge of the rooftop, the signal is affected by the Fresnel zone Solution 1: a longer post. Solution 2: bring them closer to the edge of the roof, thus avoiding signal bounces and interference due to the proximity of the ground

[@Timichaud]

I was about to say the same... botton fresnel is affected for sure and can cause problems with each polarisations and making final throughput lower or fluctuating.

[@maigonis.elleris]

Placement can be better + test other channels, reduce TX power and enable channel bonding.

[@mervstar]

@Defcon87 With how close the two devices are (around 100m) and with the link operating at 60GHz, the freznel zone is tiny enough (estimated to be around 50cm radius) that the rooftop shouldn't interfere with the freznel zone. 5Ghz however probably would be affected though.

[@astronichols1900]

I know nothing about how frequencies in this range are reflected by objects on the ground, but I imagine there are all sorts of weird reflections off of items on the roof. And with the antenna that close to a ground plane with the wall at the edge and a gap between the buildings, I'm not even sure what that would do. I bet raising the antenna just 2ft higher off the roof would make quite a difference in consistency. Would be interesting to see what the error correcting mechanisms are actually seeing and doing. Edit: everything I said is speculation...

[@thatguy5801]

Fresnel at 60Ghz is so tight and narrow I doubt its the issue, running the PTP at -30 is definitely not a smart idea, both antennas are basically screaming at each other which could be causing signal wash. The signal would improve dramatically if they'd lower the output power and aimed for -45 or -50dbm, I would never leave a dish at anything below better than -45dbm you're asking for issues down the road.

I just wanted to note that that radio has an SFP+ port and they installed an ethernet module. While it works, given the opportunity I would have suggested using fiber modules instead. Lightning can't travel over fiber. You would still need to provide the 1G POE connection to power the radio but that is much easier to send off to an isolated switch and not plugged into the main network. Fiber is way better than any lightning/surge arrestor that has ever been made.

[@darioampuy]

The antennas are too close to the roof, so there is a substantial reduction in signal quality because fresnel zone... I bet raising the antennas 3 more feet will make the connection even faster... Also since those antennas are rated for long ranged you should reduce the power to the bare minimum... I bet Ubiquiti can help tune them for you

[@tarajoe07]

YES! Know your Fresnel zone!

[@al_exs]

I don't think they are for long distance, at work we used some other brand that also use the E-Band for high capacity and the recommended distance was about 3 Km. The ones we have are 2 Gbps but we are looking at getting other brand that has 20 Gbps over the air, cant remember the distance on those but is not that long distance either. Alignment on those kind of antennas is like turning the alignment bolt 1/8 of a turn each time and wait a few seconds for the radio signal to stabilize, and they moved so much each time, it's so close it doesn't matter that much but -38/-44 on a yelling distance is not that good

[@MoreMeanThanAverage]

@@marcogenovesi8570 Chill out felecia

[@JesseKreis]

I'm sure you guys know what you're doing so this info is maybe more useful to others that are installing PtP radios. I'd be curious what the signal gain is on the radio, -37dbi is quite high for that short of a link. Usually you'd want to aim for -50 to -60 if possible. You should make sure you aren't oversaturating the radios as too high output can cause the uplink and downlink to interfere with each other similar to someone shining a flashlight in your eye while trying to read words off a page. Also, performing a spectral analysis is a very useful step as well. The uplink and downlink carrier frequencies can't use the same frequency, so it's possible that one of those frequencies has more interference in the surrounding environment. You may be able to change to another channel to get closer to a 6G link and additionally choose a wider channel width if the interference in your area allows for it. Check to see what the MCS methods are for up and downlinks. If they aren't at 15 then you probably have an interference issue. Look into "fresnel zones", as others have mentioned, the edge of the building may be causing a problem with the vertical signal. Anyway I'm no expert but I've been installing Ubiquiti PtP for close to 5 years and that's just a few things I like to look into.

[@tysons6437]

It's all about modulation. Do a link planner get expected signal and line them up with scopes and fine tune. If your over 10 off expected signal your on a side lobe which is crazy easy to do on millimeter wave by the way. Once you've achieved the best possible signal is when you tweak the eirp and power output to achieve the best modulation. With 5g a -50 is more or less best practice but with and mm wave you want that extra oomph to mitigate rain fade, especially if it's your only connection. But as close as it is rain fade should be minimal. Just my 2 cents. Been installing ubnt gear since around 2010 when they came out.

[@addaedans]

Just what i wrote... :D

[@cheesofile666]

This would be interesting for them to cover.

[@devrandvar]

I installed a few older models of these a couple of years ago, not the 60 ghz one, but 5 ghz and 20 ghz. What I think is happening here is the 5 ghz is connecting well but the 60 is not. The 5Ghz is giving you the 1 gigabit and every now and then the 60 happens to connect and give you more. At that range the 60 beam would be so tight it would probably just be like 2-5 cm. The farther away you are the wider the beam spreads so being too close can make it harder to align. As you got 3 gigabit for a while you are probably really close to the 60 working, it just needs to be fine tuned. The dips below a gigabit that you were getting are probably from the Fresnel zone of the 5 ghz, it would be around 2 meters at that range, so it is bouncing off of the roof a bit. Ideally your dishes need to be a bit higher up, but that would not matter if the 60 was connecting solidly, as it's Fresnel zone would be less then .5 meters at that range. To get the 60 aligned I would recommend to set up a script that keeps a constant file transfer going and a way for you to monitor the speed while you are on the roof, then to just turn the knobs on the dish a tiny amount at a time from both sides. Wait a bit to see if anything changes then keep doing it until you get it. Considering how tight a 60 ghz beam is it could take hours. I never worked with anything more then 20Ghz and even that was a pain sometimes. With 5 ghz you can usually just eye it and it is fine, but it can take hours to get a 20 lined up well, especially if you are too close. One time on a close 20 ghz link it took us 3+ hours to get it aligned and you guys are even closer and using 60, so it could be really tedious. I really wish that this sort of dish came with a perfectly aligned laser mounting point on them, so you could clip on a laser dot and just line up the dot to a target point on the other dish.

[@markdee3506]

To start off they need a more solid base to mount it to. And yes high frequency is horrible to align. Done some 80ghz kit links around 2 miles, it's so sensitive that you notice a quarter turn on the fine adjustment and also see it change when you try and lock it off after you've finished fine adjustment. Can take a while to even get a link initially, even if it looks spot on. The kit I've setup had a special plug to connect a multimeter to, it gave out a small voltage which allowed for near real time monitoring of signal while adjusting. I would be interested to know if the ubiquiti kit shows a signal levels for both 5ghz and 60ghz, I would assume they would or it would be near impossible to align the 60ghz properly. A mounted laser would be a bit pointless at the ranges these can do, but often there is a mounting option for a scope to do the initial alignment.

[@namAehT]

IIRC these come with an alignment crosshair that they just straight up didn't use lol. You can also DIY a headphone adapter to plug into the aux port and adjust by tone, just put on some headphones and tweak it around while listening. Sounds way easier than keeping one eye on link speed.

As a server guy, please test the link speed with iperf. File transfers are always limited of disk speed and software limitations, but iperf is designed to be used as server to server speedtest, so shouldn’t have any such limits. And it is preinstalled on your TrueNas box. I believe that the sudden jump in speedtest net may be because the server you’re testing against has already some load and most people have higher download speed than upload so as the server likely has symmetric or fiber, there isn’t as much congestion in upload.

Just a tip for next time installing a wifi bridge, those thing need some clearance from the floor, technically you need to leave at least 80% of fresnel zone free (a imaginary elliptical tunnel), eyeballing the distance a bit at 60ghz is about 1 meter so a pole 1,5 to 2 meter should do the job, with the backup frequency at 5ghz is about at 3,6 meter. Also you should consider the reflection of the floor can inject into the wifi bridge but the irregular not metallic floor should be enough to ignore it. Hope it helps. Source?

I once inherited an infrared laser inter-building connection like that, and it sucked beyond any description I could use in writing. The two buildings had completely different construction types and therefore, expansion rates as temperatures changed, and to align it you had to put on infrared protective goggles, and use an IR sensitive "target" which made the dot visible - with one person on each roof (itself a complex arrangement on one end due to security arrangements), you then had to tweak the vernier screws on each mount to centre the infrared beam from each in the centre of the target receiver (which was only visible to the person on the other roof, so communication was essential - back in the early days of hand-portable cellphones this was a big deal, and our department had exactly two, never to be allowed out of the office, and just for doing this regular realignment. With all the incoming WAN connections in one building (256kkbit/s to larger sites and 64kbit/s to small ones) and the main servers in the other (political decision), it was a chronic single point of failure in the whole national network of a major utility. Twice a day, minimum, we had to adjust those cursed things and my first action on inheriting them from my predecessor (guess why I replaced him) was to order a pair of diversely routed dark fibre connections between the buildings, with suitable transceiver equipment to translate to our 16Mbit/s token ring between copper and fibre at each end. Network availability jumped from 55% (essentially unusable) to >99.9% instantly on the first of the pair of routes being commissioned, and I got a very nice bonus :-) We were never able to get to the magic 99.99% availability as occasionally the WAN links would reset :-( It was in making this suggestion at project meetings and having it dismissed by my predecessor (while the team manager was present) that I became a network manager - a considerable promotion. It has taken about a quarter of a century for the technology to be ready for prime-time deployment, and we were the poor suckers that were at the bleeding edge. I later deployed the very first token ring switch (developed by Madge) on the same network. I still kinda miss the graceful degradation of token-based networking over CSMA/CD which saturates exponentially but fully switched ethernet did cure pretty much all of that.

Adjust twice a day? Wow, grim. Gotta love those multiple points of failure setups, you never know what you might walk into in the morning. I almost went with the same laser system (about a mile), but there was a chance of decorative trees growing up in the way. Glad I skipped that idea now.

I will say a quick tip to fine tuning alignment especially of PTP links like this, if the RSSI indicators on each side are not equal to each other (especially for a symmetrical link), then that’s typically an indicator of which side is not pointed at the other. If the remote is higher, that means the other side of the link needs to be aimed more at the local side’s dish. If the numbers are vice versa, then the same situation applies to the local dish needing to be aimed more directly at the remote dish.

I'm curious as to why you decided to use wireless for this inter-building connection instead of using the existing underground conduits in the park (a normal feature of this type of office park and clearly seen in the video when you got 10GB internet installed) and run fiber between the buildings? Getting dark fiber pulled would probably not have cost that much more than getting the runs to the roof done in each building. It would not be subject to weather, not be a potential hazard to the longevity of your roofs, and faster since the fiber could run whatever speed you wanted between your buildings. Also reduces your liability if one or both of those antennas get blown off the roof in windstorm and hits something or someone. Once the fiber is run, there is no additional cost for the fiber as this is fiber you own (and are responsible for) run in the telcom right-of-way for the park. I have done this multiple times with great success.

[@ifur]

That might be the final solution, I questioned the same

[@williameldridge9382]

They specifically said that is not a possibility. If it was, they would have done it. Were you watching the same video? I've dealt with many office parks like this myself and NEVER seen connections between buildings. Between suites in the buildings, but never between buildings. Second, running those cat5e cables to cost almost nothing....like....literally negligible. They probably spend more on toilet paper. Running fiber between two buildings? Even if there was miraculously conduits between the buildings? Talking hundreds, if not thousands of dollars. On top of that, the ISP would OWN the conduits and would never authorize a customer to run their own personal cables through them. As far as your reference to the roof....those roofs are meant to hold snow, and a 2 foot depth (which is quite common) of snow on a roof can weigh up to 19 tons or more depending on the size of the roof. There is absolutely NO WAY having that satellite up there is in any way causing structural damage to the roof. Also, each of those cinderblocks weighs roughly 38 pounds each (more than the satellite itself), and with 4 of them on there, plus the weight of the stand itself, plus the very small size of the dish....it would take hurricane force winds to remove that thing from the roof.
