I installed a system composed by one wAP 60G and 6 LHG 60G @ distance of 300-600m from the AP.
I noticed an instability on the wAP: if one station is moved or the signal drops, the wAP disconnects all other stations and it locks untill someone disables and enables the w60G interface.
Does anyone experienced the same behavior?

Solid mount is way way way better for 60G! I had a problem with quickmount when winter came. It was fastened during the summer, and in the winter couple of LHG's was pointing to the ground! Plastic shrink in winter, and screws got loose. Since I have solidmounts for 60G, I used it's mounts (now called and sold as LHG mount https://mikrotik.com/product/lhg_mount) to fix those loose LHG.

Much thanks Blue!
For the solid mount, or any of them, is there a graduated controlled click during turning in horizontal or vertical directions?
(or does one loosen bolts and move free form)?

Of course I am still also trying to get my head around how you get something one mile let alone 5 miles apart aimed close enough in the first place to think about refining?
For example, is there target material you can put at an expected location (for pointing a laser at for instance).
Then attach laser somehow (parallel to beam of antenna) and aim it at target sight??

Re: LHG 60G experience

Posted: Sat Feb 23, 2019 5:18 pm

There are no click. Use wrench 10mm and finetune it. Than fasten all fixing bolts and that's it. I never used laser for pointing. Years of experience and google earth helped me to point antenna in desired direction. But since LHG60 is only 1 degree You absolutely have to use solidmount on greater distance...

60GHz - 4330 meters - my experience

First of all, if You don't want to read my whole post, conclusion is don't do it - maximum reliable is 3000 meters.

Finally we had some sunny and warm days in Serbia. So I reserved whole weekend for 60G links. First of all, You need a lot of patience. When this long link got disconnected for more than couple of minutes it takes anywhere from 30min to more than 2 hours to get back online! I don't know why? Reboot, unplug/plug din't give any results.

We combined LHG60 with SolidMount, and that is a MUST on any 60G link that is 1000m+.

When You adjust the link use bandwith test between two devices. It is powerfull enough to let UDP trafic spread it's wings. TCP got stuck arround 500Mbit with 100%CPU.

Don't look at the "rssi". You only need MCS (max is 8), SIGNAL (100 is ideal so I assume that is in %), and try to get TX-SECTOR to center. Also Error rate is crucial!

Don't use "align" since it disconnect link more often. Use only "monitor" tool.

One person should be at the antenna and another should look at the notebook. First get 60G link to any working order with eye sight. I know that it could be difficult for someone, but LHG60 have mesh grid and it is see-through. Then You need wrench 10mm to finetune solidmount. It takes half of the turn to lose signal. So it should be fastened to maximum allowed to turn the wrench.

And then start to play. Don't be afraid to try different things and positions. Most annoying is when You got disconnected for more than a minute! Than it takes forever to get connected again. It is not a matter of misalignment at all since once we got disconnected for 2 hours and after that link got connected and we had MCS 7 and Signal 80. Bandwith test was 900Mbit.

Next day it got very windy, and link got worse. I was thinking what is somehow moved, but after wind has stopped link got OK again. Also rain is killing this link, but 2950 meter link is holding OK in wind/rain.

Now winter came back in Serbia for a few days, and on first warm day I will take down this 4,3km link since it is useless on that distance.

BR to all and good luck (You will need it - at least until Ubnt start to sell 60GHz) :)

Hi,

Earlier today a network loop was introduced in our internal network. While investigating the source of the loop we disconnected the 4 links with other buildings that we have using LHG60s and a link with wAP60. While rebooting one of the LHG60 links the devices never really came back.

I thought it had to do with the network loop and did not pay attention. When the loop was discovered and elliminated (someone connected two adjacent network sockets by mistake) all links and devices came immediately back and I could access their interface except from a specific link.

When I try to ping their IP I get a couple of pings and then maybe 10-15 requests timed out and the same things repeats. At the beginning I thought that maybe one of the antennas has died but the strange thing is that BOTH master and slave behave the same way.

Even when pinging the devices from their respective side the same thing happens which leads me to suspect that something else is the underlying cause.

When checking the LED lights on the devices the pattern is equally strange. Upon rebooting the power LED switches on and then the ethernet LED switches on and blinks as expected however as soon as the wireless link is apparently established and the wifi LED is on then the ethernet LED starts blinking really slow instead of the typical fast rate blinking when traffic is going through.

Any suggestions? Or should I RMA them and replace them? I bought these like 6 weeks ago.

Cycling timeouts like this are usually caused by STP blocking and reenabling forwarding on a port in my experience.

Friends, help calculate the track and its reliability.
Going to do PTMP.
As the base I want to use Wap
The first client at a distance of 160 m. LHG
The second and third on the same building at a distance of 490 m. LHG

How much such a link will be reliable, whether there will be frequent problems with it. What signal do I expect from distant links?

I am reporting some weird findings. The device is connected on an HP A5500 48port PoE+ switch worth 7,000+ euros. There are 3 other LHG60 on the same switch all working properly/normally. There are 35 VoIP phones on the same switch all working properly.

Even when switching off the PoE power from the switch port the antenna stays on! Or at least its LEDs are on.

It will only go off when disconnecting the ground cable!

The weird findings continue. When disconnecting the ground cable the problematic antenna comes back to life and the link works. When connecting back the ground cable it goes crazy again.

The same ground is used for all the other 4 LHG60s on that roof and the rest behave/work normally.

Should I use the ground or not? Is it better to use the Ubiquiti surge arrestors instead of the ground? Should I use both?

I had people check the earthing itself and it is fine.

I could not find documentation on the matter

LHG60 is great and available (for a while now). It runs ROS which is way better than AirOS. So wrong thread to blame them sleeping. This new gear looks very small. So I guess gain is between WAP 60G and LHG60G. If you need 5GHz Backup use SXT or combine LHG60G with af5xhd using a powerbox pro.

On 60GHz WAP radio PCB, there is place for 5GHz radio chips, but it was never used. Mikrotik appears to be just sleeping, while competition is creeping closer and closer and may beat them at their own 60GHz game...
Hopefully this will be a wakeup call and we will see some new 60GHz gear soon. They must have known about Ubiquity releasing their 60GHz solution for some time.

Next months will tell us more.
- if we see new 60GHz radios with real new features and improvements, there is still hope MIkrotik R&D have been actually doing something for past months. Question is how long it will take to get new devices certified and released to the market
- if no new devices are announced or they just release minor updated version (let's make a dish metal and call it a day...) it's probably not very good sign. At that point all that Mikrotik can do is they can start lowering the prices of existing 60GHz gear when Ubiquity releases their 60GHz hardware, but that would mean they have nothing new and all they can do is to lower prices to stay in the game... not good.

The range will depend on the used antennas. PTP links will be part of the mesh. I hope different Vendors will be compatible as Radwin and Cambium has announced terragraph, too.

You need to point very well, and the money for solid mount is a good investment,
And then such Link will work in most conditions

Thank you!
This is working perfectly.

Hi

Should I use the ground on the LHG60 or not? Is it better to use the Ubiquiti surge arrestors instead of the ground? Should I use both?

Does anybody have any documentation on it? I cannot really find any proper documentation for the LHG60

Thank you

Hello little info and I need some advice.
We have 3km 60G Link already deployed almost 3 mounts ago
Ap Side
----------
connected: yes
frequency: 66000
remote-address:
tx-mode: dmg
tx-mcs: 8
tx-phy-rate: 2.3Gbps
signal: 80
rssi: -60
tx-sector: 6
tx-sector-info: right 1 degrees, down 1.4 degrees

Overall, we are satisfied, and yes on a moderate rain link drops occasionally

08:31:46 interface,info wlan1: link down
08:33:43 interface,info wlan1: link up
08:33:43 interface,info wlan1: link down

08:38:03 interface,info wlan1: link up
08:40:16 interface,info wlan1: link down
08:40:19 interface,info wlan1: link up
This is from today's rain, link was down periodically
After 8:40 Rain was light and link was stable.
Yearly we have very little snow, and heavy or tropical rain are common here but they last very short 5-10min.
Overall that is what we have expected, and the link is 99.5% of the time usable.

I saw some posts of dudes like Blue (love enthusiasm) have made links up to 4km and record 5km lol that was excellent.
What I need is some advice, we want to deploy 3.45km 60G Link (of course with 5Ghz backup) what should I expect? Is it going to be usable nearly as my 3.1km link, or it is going to be total waste of time?
Thanks.

Can Microtik interwork with other 11ad hardware?

How to setup Microtik 60G as STA that connects to another vendors who acts as AP?

So far we've been able to make Microtik60G to another Microtik 60G to work. Is this by design/intent?

Thanks

All Mikrotik 60G hardware is so far compatible, so you can mix LHGs and WAPs as you like. But don't expect it to work with other vendors, even if it uses common 802.11ad platform. Everyone is playing on it's own playground, there is no intercompatibility due to customized protocols and different vendors design devices to lock you in on their platform to buy their devices... nothing new.

I'm not quite sure about the full compatibility between LHG and WAP60g. WAP60g seems to have some internal distance limit between clients, which Mikrotik is gradually and secretly extending, without any informations for the users who purchased the device. All we have to do is to firmly believe that Mikrotik (before the competition comes up with something better) quickly releases the FW, which again allows (at least for the initial setup of the link) fixed settings not only for TX-sector, but also for TX power, MCS, ACK, etc .

I'm starting to use WAP60 to connect customers in PtMP setup.

Is there any way to connect the wireless link to radius? this mean a LHG60 STA only connects to AP if radius autenticates.

Thanks!

The smart vendor includes compatibility with other vendors equipment when possible, kinda like how Russian rifles were designed to use Russian bullets but also NATO bullets.

guys please. Vanilla 802.11ad is just like vanilla 802.11b or n.
there are certain things in the standard. also, the standard is from 2012, and it was never ever intended to be used outdoors at a distance. because of oxygen absorption. yes, there are vanilla implementations out there, more or less for indoors and not using phased array antennas.
the other thing is MAC. if you want to use vanilla .11n or anything 802.11 in a multi-access scenario, it sucks. because vanilla 802.11 MAC sucks. that's why vendors implemented their own TDMA based stuff, to somewhat control the inefficient behaviour of the WiFi clients. Or synchronised APs.
this is no different here. if you want to use a purpose-built device in a certain environment what the device was optimised for, then you can't expect something very generic to be compatible with it w/o serious compromises to its original goals. Mikrotik did not intend to build a 'generic' .11ad AP. this thing is for outdoors, it uses technology that is 4-5 years younger than the original WiGig standard.
back at that time receiver side beam forming wasn't widespread, and the original standard did not rely on that. as the result the maximum distance it was able to operate with was literally meters or maybe 2-30 meters. you have here very precise beamforming down to 3-4 degree or so, both on transmitter and receiver side, just to concentrate all available RF energy into this tiny beam to bridge the massive free path loss in the air. so you can reach over 100s of meters if required. or coordination between the clients. none of those were part of the original standard, so each vendor, each silicon manufacturer had to figure this out for himself.
what exactly do you expect? to operate a 60GHz based (most probably proprietary) video headset with it?
i've seen the prices of other vendors, even the ones who use the same BB and RF as Mikrotik. we're doing great here.

on the other hand, the next standard - 802.11ay - already includes specific things that are required for proper outdoor operations, like synchronisation, TDD/TDMA, transmit power control, god knows what. there is a lot more chance to see actually compatible equipment - if not more than compatible at PHY and MAC layers - when vendors start adopting silicons from certified .11ay chip manufacturers.

this error rate is way too high. also notice that the AP side uses lower modulation scheme (7 vs 8).
most probably you get quite some noise there. i don't know your setup, but it you line up your relays back-to-back, and use the same frequency on both of them, you might get some interference from the next link.

I understand that the question will sound silly, but even so, I will ask it.
How did you achieve these indicators, did you use special fixtures?
And as you reduce the antennas, I have a line at 2,300 m and it behaves very well, but sometimes it does not work and to reduce to 1500, the signal jumps too much and it fails to achieve good, and as I wrote above, after 30 minutes, the signal DEPENDS.
And you have to reload the antenna.

Hi all.
I have read through the forum, that there are already installers, who have mounted the 60G lhg at a distance between 1.5Km and 3Km .. And I would like to ask, how does it behave in moderate rain to strong ...
I would also like to know if anyone has thought of using the LHG XL HP5 plate, for an Lhg 60 .. We are talking about a 550mm plate with a brake diameter of 390mm. I suppose that for the distance that I have mentioned, it will make it more stable.

Thank you

Hi!

I have a strange problem:
- 2x LHG 60G link, 395m
- RSSI stable at -50 to -52 dB, Signal-Quality 80-95

Next to the LHG on one side, there is a large (3x3x3m), rotating advertisement-cube

When the rotation of the cube is off, the link is 100% stable. When I start the rotation, the MCS drops down from time to time from 8 to 6 or less.

What I tried is to disable auto-alignment (tx-sector=36).

Do you have any other idea on how to solve this?

Thank you for your help!

Ask Mikrotik to finally publish the LHG60g radiation pattern, then everything will be clear. The situation has been unacceptable for so long time, we have a broadcasting device and we don't know exactly where it is broadcasting.

Hi

60ad mikrotik is Higly unstable when:

-raining above 600m

-snowing ( wet snow) kill even 300m links
using RADOME helps snow downtime : but decrease rssi about 5db
~~10hour link on 500m was dead without Radome
~~20minutes same link with radome after wet swnow


i have ~~ 12 links on lhg backup'ed with 5g and ospf.

We have found some interesting experiences working with the LHG 60. We have a PTP link that is 373m. During initial setup we aligned the dishes and locked them in with an RSSI of -54 (MCS 8, Signal 80, PHY Rate 2.3 Gbps).

We have been tracking TX-Sector, RSSI, MCS and Signal using PRTG and have noted some strange anomalies. The link appears completely stable and polling the data above every one minute shows it is rock solid, but then out the clear blue, the TX-Sector will suddenly shift and everything changes. When this happens the signal will usually drop (from 80 to as low as 50), the RSSI will go up (anywhere from -60 to -70) but the MCS will usually stay steady at 8.

The first time this occurred, I thought perhaps a wind gust had shifted the dish, so attempted to revert the TX-Sector back to the last best TX-Sector (from 34 to 11), but that caused the Signal and RSSI to vary constantly, so I switched it back to auto and it settled down to a new sector (63) with a much better RSSI and a solid signal level of 80.

It ran solid that way for about 24 hours and then once again, for no apparent reason, the TX-Sector suddenly shifted causing the signal to drop to 50 and the RSSI to jump to -70. But, even with the poor RSSI, the MCS stayed at 8 (PHY 2.3). I let it run that way for a couple of hours and during that time there appeared to be no loss in throughput and no significant latency. The link remained rock solid despite the odd readings. Eventually, though I toggled it from auto TX-Sector to manual and back again forcing it to realign, after which it settled at about -64, with a signal of 80.

As I said previously,the first time this happened I suspected wind gusts as we noted some guts around the same time period, but in all of the subsequent shifts, there have been no significant weather changes.

One other interesting observation is that when it makes this shift, the link does not drop (which is good). I am polling the data once every minute (as well as logging it) and note that it just seems to suddenly jump from one sector to another, with no searching or hoping around.

Ah, I'm experiencing exactly the same! I had this with my first link (500 meters) and spent a lot of time adjusting and aiming. In the end, I let it settle for about two days and it seemed to lock to a certain sector. Signal steady at 80 and rssi -51. I then picked a center sector (36) and locked to that on both antennas (I was just trying things out).

Now, it's up and running for 60 days and it hasn't changed one bit! Not even with rain. Just no change in signal, rssi or MCS. I ran a hackathon over it with 1200 devices without any problem.

I'm configuring a new, second link on the same roofs now and I have a lot of trouble getting it right. Of course I'm running on another frequency, but choosing the right one is strange. When picking 60480 (first link is on 58ghz) and letting it run for a couple of hours the signal and rssi jumped all over the place. There was half hour without any tx-errors and a steady signal of 80. Then it just jumped to another sector and then stayed at 60, MCS turns down to 1 and it stays that way... Then choosing 62640, the signal stays on 95, MCS 8 and rssi -54, solid for some hours now. This is without any change to alignment of the dishes. I still have tx-sector set to auto now, but when it works I'll set to a locked sector.

I also couldn't think of any reason why the sector suddenly jumped apart from wind. The pole has a little slack with higher winds. I'll keep monitoring when wind changes.

Hi!

Did you find any possiblity to get valid RSSI-values?
I see fluctuation over the first 5 minutes. After that, RSSI is unchanged for weeks - no matter, if there is heavy rain.

On thunderstorms, sometimes the RSSI dropped and did not get back to the "real" value without dropping the link manually or starting "align-mode" for some seconds...

Thank you and best wishes

The latest version 'd have the viewfinder that helps a lot to make the first alignment after you may use via cli the command: int w60 align 0 using the average rssi as reference

use the solid mount adapter https://mikrotik.com/product/solidmount for fine alignment

Hello.
We have a 60G link what works well for days. Random time the station device is unreachable, but passing traffic. I need to kick from the ap (bridge) side. When it comes back it works well again. One day after it happens again.
