Re: LHG 60G experience

Tue Jul 24, 2018 11:53 am

ROs v.6.42.6 , link up with low rain and wind 28 kts.

Notice no Tx-sector info in master device using winbox window, I must use monitor via terminal.
If I tryed to center the devices , RSSI value increses. I have a good RSSI without center the devices.

Please show the other side.

Hi guys

what version of firmware is ok for LHG60? I 'm not sure but with 6.42.6 the RSSI level is worst than 6.42.5 and I read on the forum that 6.42.4 is better than 6.42.5

Any advice?

Thank you

We’re sticking with 6.42.3. We never tried 6.42.4 before we tried 6.42.5 and .6, but .4 should be OK as the only w60g change was “improved RAM memoy allocation processes”

Something weird I noticed: It stopped raining since around 30 mins and suddenly the LHG60 link dropped to MCS 1 even with a good RSSI (-55 dBm):
frequency: 64800
mcs: 1
phy-rate: 385.0Mbps
signal: 20
rssi: -55
tx-sector: 41
tx-sector-info: left 1 degrees, up 0.6 degrees
rx-sector: 96
distance: 1166.37m

The link stayed like that until I passed some heavy traffic through it and then it when back to more normal values:
mcs: 8
phy-rate: 2.3Gbps
signal: 80
rssi: -55
tx-sector: 47
tx-sector-info: right 1.4 degrees, up 0.6 degrees
rx-sector: 96
distance: 1166.36m

No idea what is causing that...
I'm seeing this as well in 6.42.6 with no rain and full LOS. I'm not sure why on first boot and install the MCS, signal, and phy-rate is pretty stable but over time it jumps around for no apparent reason.

We have a 1.2km link with LHG 60G's, properly aligned, with signal around -68dB. Link drops immediately with the slightest rain. Since we're using BFD and have a 5GHz link as a backup it's not an issue, but I wonder where the signal difference with some others (e.g. @cohprog) in this topic comes from. It seems most people have signals in the -50's at the same distance.

Did you aligned based on the tx sector info or the rssi? Imho, result is better when using rssi. The sector info randomly vary from "center" to +/- 2 degree in my case. With the wAP60, it's a lot worse: over 50m, the sector info vary by +/- 20 degree or so.

I am running on 6.42.6, frequency is set to auto. Disconnects are too often - 230x for 4 days uptime is insane... Distance about 340m.
Clear LoS, no rain for 4 days... any idea what else should I check?

LHG 60 left/right alligment tool :)

size of clamping is 90-110 cm

It helps a lot

remember correct alligment requre
- set 58ghz (not auto)
- do bandwith test UDP 500Mbit symmetric between two lHG 60
- monitor via terminal interface w60g monitor interval=1s numbers=0
on both sides
- you should have same rssi on both side (eg 1950meter link has ~~ -62 rssi on 58Ghz and -57 on 64Ghz)

RSSI is only one real information to correct link alligment

differrent link rssi to frequency on 1950m link
-63/-64 chanel 58g
-68/-68 chanel 60g
-68/-66 chanel 62g
-58/-57 chanel 64g


And its my simple clever helper to left/right allign ( its fu... u... in original mounting)

Hi you should make correct alligment,
i had same problem on 1950m., after correct alligment link works stable

We aligned it based on tx-sector-info (more specifically, one device was aligned by the LEDs indicators on the device, the other was aligned from the terminal because the LEDs drove me crazy).

Try to align based on the RSSI. You should be able to get a much better signal.

we are having loads of disconnects. Up and down constantly signal is solid at -53.

If we load 6.43rc5 no disconnects at all.

All the newer versions constant disconnects. Any ideas on how to solve this?

We are currently on 6.43rc45

Same here. 6.43rc40 and 6.43rc44 both have constant disconnects on links that are definitely not overlimit - one is only 25 metres!!

FYI 6.43rc51:

*) w60g - added distance measurement feature;
*) w60g - fixed random disconnects;
*) w60g - improved MCS rate detection process;
*) w60g - improved MTU change handling;
*) w60g - properly close connection with station on disconnect;
With great knowledge comes great responsibility, because of ability to recognize id... incompetent people much faster.

rc51 seems OK (so far) for point-to-point. Still seeing a lot of disconnects on multipoint. :(
6.42.3 continues to be my favorite firmware for these radios.

Greetings all! Couple of questions straight away:
How does LHG 60 act with interference? As soon as it was announced in the shops, I see them almost on every tower now (We have A LOT of competitors). Taking into account that it has 2Ghz bandwidth I can only imagine what is going to happen. And no one knows exact antenna pattern, how wide it is. If it is flashing all around, for sure it will affect link across op opposite or even...somewhere. Ok, it is well known that on this freq there is a lot of attenuation, but locally it may cause (or not?) problems.

Ok, we have siklu 60G band relays, and those guys all around started to mount LHGs, how they co-exist? Taking into account that they like to overpower radios, I am very worried that a 200 bucks toy can affect an expensive piece of hardware, which is a bint unfair first of all.

Anyways, I have ordered 3 pairs of them, because it is sure a good value for the money to replace or backup overloaded 5Ghz links, but still..To me it seems like I bomb in monkeys hands.

60Ghz signal drop very fast with distance because it's absorbed by oxygen so even links that are very near to each others don't interfere much. I didn't try with LHG60 but I didn't had any problem running 2 Metrolinq back to back on the same channel (and they don't have gps synch).

v6.42.3 is indeed much more stable than 6.42.6. I had fluctuating signal quality and MCS and many 8s linkdows. With 6.42.3 the signal quality is stable 80-95, MCS mosty 8, and only one 1s linkdown a day. Link length 386m.

Testing a point to multipoint setup. 4 clients all under 240 meters. Speed is great but disconnections are very often. In my experience if one link has poor signal -70dbm and it disconnects it caused all the other stations to disconnect just after the poor signal station disconnects. This behaviour is repeatable. I think once MT can perfect the software it will be very good but right now seems a little unstable.

We have the same setup with several PTMP tests, clients all under 200m:
- when one client reboots or loses a connection, all clients drop connection for a few seconds
- latency / jitter doubles every time a client is added
- RC56 has not made much of a difference
We also have several PTP test links under 1000m:
- RC56 seems to have helped a lot with random disconnects
- Struggling to get good RSSI reading which also seems worse after upgrading firmware
- Still dropping in heavy rain

We found that the installation location is more important than one would assume on a building or roof (was expecting the narrow beam pattern to do the work)

as my experience when rain is started its always going down , Pls looking and support





Hope to have soon a feedback in a rainy day :-)
Rain rain rain.. We need more real live testing. But.. Todays situation about 40-45mm/h link was down for 4 minutes going from -56 to -70 in few seconds. The wet antenna takes -4dB!! Link length 1300m.
The link nearby with WAP for 400m was doing well all the time loosing approxiamtely 1-2 on RSSI scale looding from -66 to -68, and already working as before the rain. LHG is 15 minutes after rain still -59 and once dry has to come up to -56.

Hi, How did you configure the 5ghz back up? Im hoping to do the same with a pair of powerboxes and a pair of powerbeams to back up the LHGs. Im not familiar with BFD.

Cheers,

I've seen max distance specs on the products and testing for WAP60 to WAP60 and LHG to LHG, but what about WAP60 to LHG 60? I assume that would cut the 1500m limit down to what, 1000m?

With rain fade I wouldn’t go any more than 800m on the LHG to LHG

Our 1000m is dead as soon as you get a downpour

We have found that if you lock the tx-sector using the cli and do the alignment, once you unlock the tx sector, the rssi gets better by 2-5 db. Not sure if it would get there without this procedure tho. Since there are 64 sectors, we lock it to the middle. We don't bother with the arrows, we look at rssi only.

The problem we have is the feedback loop is to long. When you make an adjustment, the rssi won't update for seconds. I assume this is because the chipset is evaluating all the sectors rx signal. If we could lock the tx and rx for alignment mode and have more frequent rssi updates it would help to get a proper alignment. In my opinion the process should start with aligning the radios for dead center with locked tx/rx. Once it's dialed in then turn on the beam forming.

Me also lost a lot of time trying to get my 2,2km link working. Info from cli and winbox is very slow. From time to time i had to wait for 15-20 seconds for information to settle down. Hope that we will get some more precise alignment tool. I hope that 802.11ad don't end up like spectral scan on 802.11ac.

Right.....

I hope for some more features in 802.11ad

- Smaller channel width

But the hope is gone almost for 802.11ac

cohprog,

What monitoring software is that?

Zabbix. There is no pre-made template for LHG60 but it's easy to do one. (there is a script that will do a snmpwalk and generate a Zabbix template based on it)

6.42.7 and 6.43rc64 have very important enhancements to the tx-sector selection.

I have been following the betas and the stability has improved a lot since rc56.

The original bracket is not convenient for smooth adjustment. I use this one : http://www.cdr.pl/p6418,uchwyt-precyzyj ... adkit.html but with the addition tool from Metrolinq.

Is the new channel still only available in CLI or did they finally add it to winbox in the latest RC?

I am running on 6.42.6, frequency is set to auto. Disconnects are too often - 230x for 4 days uptime is insane... Distance about 340m.
Clear LoS, no rain for 4 days... any idea what else should I check?
Hi you should make correct alligment,
i had same problem on 1950m., after correct alligment link works stable
Nice dude 1950m stable link good news, I've done 1560m link works very stable, I was sceptic about 1750m but now I m going for it.

The LHG 60G pointing to proper direction is impressively imprecise, which is strange with that beam forming and all. The link signal will cut off by only minor adjustments thus these "0.2 degrees left or right" are almost funny. What is the antenna pattern and how that device is using it?

Just to make a quick experiment: unsoldered LDF patch antenna and put it in the centre of the LHG60, The loss is high 8 to 10 dB compared to the LHG 5AC but easy solutions to make a cheap 5GHz backup using the same antenna :-)

The copper on the bottom is the reflector for the patch I don't make any calcultions only I just made it.

Dang! I think you won a certain type of silicon lottery! We have 750m link at ~-50dBm signal. Yours at 1km more should see an additional ~-22dBm fade over ours so expected would be -72. I wonder, if you found the magical beamforming TX sector. Because in reality we took down an ML2.5 link which was connected at calculated RSSI of -33dBm, replaced with this one and now only -49 at best.

Don't trust RSSI readings too much. You should be able to get same distances with ease - upgrade to latest versions, there a lot of changes that affect receive sensitivity

So what exactly do we trust? What are we aiming for, centre? If so, I have seen centre on different tx-sector. 36, 26/27, etc

I have asked this exact question in another thread. I have had answers about my radios being too close etc. I thought it was an alignment problem but we have tweaked and tweaked and cannot get any better results. We are seeing a lot of Link Downs on the Station side of our 60Ghz Mikrotik links.

Re: LHG 60G experience

Thu Oct 04, 2018 1:28 am

I am as well having issues getting these things aligned...

1) Using the LED method absolutely won't work. If I use this my dish is physically aligned 20 degrees off of the remote dish.
2) MT provides few definitions on what we are seeing on the monitor/status menus. Signal, what is this exactly? Is this is db? What are the TX-SECTOR and RX-SECTOR numbers referring to?
3) RSSI stops responding after a while and is not reliable.
4) How do I turn beam forming off? I cannot figure out the nomenclature in terminal mode to do this and again there is no documentation on this. I think if I add a number to TX-SECTOR to set it as NOT auto, that turns of beam forming, but I can't figure out what to type to get that to happen.

My goal today was to change the TX-SECTOR to 32 thereby turning off beamforming and using RSSI while it responded to align our dishes. Is there a better TX-SECTOR number to use to get alignment handled than 32?

I don't like forums, but in the absence of decent wiki docs or online documentation I am forced to admit defeat and ask for input from those who have had better luck.

A better alignment procedure would be very helpful including CLI commands. We are using 6.43.2 presently.

Thanks to anyone who can help!

I think that the correct command to shut down beamforming is /interface w60g set 0 tx-sector=32... I have no idea what the "0" is in the set command however.

Updating my prior post...

I'm be putting up a LHG-60 PTP tomorrow at ~ 1300m, will I have fade? That's about 0.85 mi or so, which in my world is across the street.

Also, upon bench testing how do I see the PHY and other stats people posted on here? I even upgraded to the latest RC (development says N/A)

The testing branch is in beta these days, not RC.
I recommend 6.42.9 for production deployment.

You are using the most recent beta. I get that too, I used montior 0 on the CLI to get around that.

"The testing branch is in beta these days, not RC.

I haven't tried 6.42.9 yet. I have been going between the current and testing versions and am neither having much luck keeping a stable link nor am I confident in my alignment.

Would you please provide an alignment procedure that works for you? Apparently we shouldn't use RSSI and the LED method has not worked for me; it sends me way off a bore sighted path.

Also, can anyone tell me the significance of what the SIGNAL, RX-SECTOR and TX-SECTOR data is and how this might help an alignment?

Interesting experiences.
I have some test kit going up soon which is by Google mapping 2.63Km clear LOS tower to tower.
I'm not expecting full PHY rates but am wondering what it will reach and how any rain will affect the link. My hope is that it folds back and doesn't go off completely.

Mikrotik is now claiming 4km (https://mum.mikrotik.com/presentations/ ... 743074.pdf) but I’m reluctant to try. Maybe with the new 66000 MHz channel?

LHG 60 tx-power missing Re: LHG 60G experience

Thu Oct 11, 2018 3:57 am

Hi, Running 6.44Beta20

No tx-power setting for the 60Ghz interfaces.

I've got several links that are very close and I suspect we can improve the quality by turning down the TX power.

Any idea when it will be a configurable option again ??

I've checkd, WinBox, WebFIg and CLI

Thank you

Without more data on stability in rain events @66000 it's not safe to pay a licensed link :-)

it's not a standard channel, special permissions usually are required to operate at this frequency.

From MUM UK
• Major received signal sensitivity improvements
• LHG60G can reach up to 4000 m distances (depending on
used frequency)
4 km what?
Is it like LHG60G signal reached 4000m but throughput was eh, than the rain start and we lost signal.

Can someone from Mikrotik give us more info.

if 66Ghz is Central freq. its illegal to use.

Hi!

66GHz sounds great, but if I'm right, LHG60 uses 2000 MHz Channel bandwidth.
In this case, 65GHz would be perfect...

Channel 64800 is near to 65000 so no need

Has anyone got OID values for RSSI? It would be nice to graph the signal during the rain, just to see how much it changes.
I've only got this from CLI:

mode=.1.3.6.1.4.1.14988.1.1.1.8.1.2.1
ssid=".1.3.6.1.4.1.14988.1.1.1.8.1.3.1"
frequency=.1.3.6.1.4.1.14988.1.1.1.8.1.6.1

Hi all

I'm starting in this world of 60Ghz .. And I'm quite surprised ... I have some doubts, since there is little information about mikrotik antennas at 60Ghz ..
For example:
The Mikrotik wAP 60G, the array says 60º. Vertical and Horizontal, or only Horizontal? . And if it were Horizontal, what is the Vertical Angle of the beam?
In the LH60G, what is the Beam?

If someone can answer me, I would like it
Thank you

Yes there is so little info about LHG60, I want to know that too. Last update was now LHG60 can do 4000m, they added 66Ghz channel so I m not sure if 4000m is only possible on 66Ghz or you can use all channels which I m sceptic about that.
Mikrotik is like '' Oh yes we made some signal improvements now you can go for 4km '' What about rain, what data rate should we expect, signal level and etc. there is so much lack of information.

66000 GHz is non standard freq for this band? Will You implement 66960 GHz and 69120 GHz?
it's not a standard channel
This source mentions 6 channels (ch5 = 66960, ch6 = 69120 MHz):

https://en.wikipedia.org/wiki/Wireless_ ... e#Channels

"Regional spectrum allocations vary by region limiting the available number of channels in some regions. The US is the only region supporting all six channels. " - is this true?

On the other hand, I've seen some other standard (intended for China) with four 1.08 GHz wide channels numbered 5, 6, 7, 8 in the same frequency range as channels 2, 3 (allowed in China).
Any chance we will see support for narrower channels? Not everyone needs a full gigabit of throughput, often can't be fully used due to the max 8 stations per AP limit.

with probably alignment you will see full gigabit bandwidth, but it will drop during rain/snow.

@server8 Have you tried this out yet? Great idea.
Could the patch be mounted on just above or below the aperture on the 60G feed? It wouldn't be the exact focal point but it might be close enough to get some gain back.
Worth a try?

I have no time to make test on field just an idea, around 2 max 3 km the link loss of the solution is high but the signal is enough to have a good 5 ghz backup in rain events

Feel free to copy it :-)

I'm just want to share my experience with PtP W60G link.
We've deployed this link about 45 days ago. Since then we have experience HEAVY rain (2 days non-stop) and light snowing. Link hasn't disconnected once and lowest MCM was 6.
I've read that people have problems with allignment but we all have because it's not easy and even 0.5 degree can make a difference. You should use terminal to see both sides and everytime you make change wait about 20-30s until information is updated. Also use ping to see if the link is table and once you feel like you got it just do BT Test.

on station side:
Freq: 64800
Signal:80
MCS:8
PHY Rate:2.3 Gbps
RSSI: -55
TX Sector: 16
RX Sector 96
Distance:399m

On bridge side
Freq: 64800
Signal: 80
MCS: 8
RSSI: -57
TX: Sector 36
RX: Sector 96
Dostance: 399

RouterOS 6.43.4 = very nice and stable

This link is in City with a clear view (from building to church)

Is lhg60 in short distance ptp scenario really able to push ~1gbps ?

I just put up a 370m link to feed few hundred users from 1gb/s fiber and I wonder if it's gonna work or should I look for more sophisticated FDX solution?

At 370m with good alignment a couple of LHG 'd work close to gigabit FD due to alignment problem with the standard bracket I suggest to you to use this http://www.cdr.pl/p6418,uchwyt-precyzyj ... adkit.html

For all of you that don't seem to be dropping, how are you aligning your LHG's and even WAP60G's if using those. My disconnects have to be coming from an alignment issue.

Are you using Signal, RSSI, sector info?

These long-range links use a non-standard and illegal 66000 frequency. Any chance for MT to implement 66960 and possibly 69120 too? Still illegal in many parts of the world, but at least standard (channels 5 and 6), doesn't interfere with 64800 which may need to work at the same location too. Or is this beyond the capabilities of current hardware?

Just an FYI, the bandwidth test tool doesn't max out the capacity of the link. For a full-speed test use the traffic generator.

I don't believe what it reports. I am looking only at RSSI. It is tricky to align it without precise alignment kit, but spend a little more time than usual since beam is very narrow (that is a good thing).

1/ not at the time
2/ it's capable of doing 1 Gbps in TCP
3/ we use this gear and it works fine. Clients (about 150 clients) don't fully utilize aggregation of this link. There's about 60kpps in TCP of traffic.

As with everything in networking the quality of your network depends on your needs. Are your Clients even capable to fully aggregate PtP 60G link ? I think you should deploy one PtP link (it's cheap af) and test it or just look at your switch and look how many pps and what size they are using.

Trying to work out if I should waste my time trying a 320 metre link with a pair of Wireless Wires?

Don't need 1Gbit - I'd be happy with 200 bit. Is this going to fly based on people's experience with latest firmware?

However, after I ran the align test, the Bridge unit defaulted back to Frequency 58320... Why does it change frequency?

Re: LHG 60G experience

Wed Oct 31, 2018 11:00 am

New beta versions has alignment mode included (it will update information much faster)
to use run from CLI:
/interface w60g align wlan60-1
Is the Left/Right - Up/Down - Center alignment working properly using this with latest 6.44Beta28 ?
This is what I am seeing when running the align test from the Bridge unit:

connected: yes
frequency: 64800
remote-address: xx:xx:xx:xx:xx:xx
tx-mcs: 8
tx-phy-rate: 2.3Gbps
signal: 90
rssi: -57
tx-sector: 36
tx-sector-info: center
distance: 1473.14m
tx-packet-error-rate: 0%

However, after I ran the align test, the Bridge unit defaulted back to Frequency 58320... Why does it change frequency?

connected: yes
frequency: 58320
remote-address: xx:xx:xx:xx:xx:xx
tx-mcs: 8
tx-phy-rate: 2.3Gbps
signal: 90
rssi: -54
tx-sector: 27
tx-sector-info: center
distance: 1473.19m
tx-packet-error-rate: 0%
I found the problem... Do Not go to QuickSet screen to check on frequency or try to select the 64800 frequency. If you do, you will notice that 64800 is not listed. And if you then exit the QuickSet screen by selecting OK, the radio will revert back to Auto and select a different frequency. You have to go back to wlan60-1 interface and select the 64800 frequency there. Or go to Wireless interface to select 64800 frequency. - - I believe that you should look at having the 64800 show up in the drop down of the QuickSet screen.

Trying to work out if I should waste my time trying a 320 metre link with a pair of Wireless Wires?

Don't need 1Gbit - I'd be happy with 200 bit. Is this going to fly based on people's experience with latest firmware?
Dude read the fcking post here. I've post that I have 399m link working 1Gbps and no disconnect with HEAVY RAIN. We talking Noah Ark biblical rain here right.

So read my post and like Nike commercial says "just do it".

I'm just want to share my experience with PtP W60G link.
We've deployed this link about 45 days ago. Since then we have experience HEAVY rain (2 days non-stop) and light snowing. Link hasn't disconnected once and lowest MCM was 6.
I've read that people have problems with allignment but we all have because it's not easy and even 0.5 degree can make a difference. You should use terminal to see both sides and everytime you make change wait about 20-30s until information is updated. Also use ping to see if the link is table and once you feel like you got it just do BT Test.

RSSI: -55
Distance:399m
Uh... your link is 400m. I certainly hope that it won't drop with such a short distance. Most problems start with links above 1km. 60Ghz is nothing like 5Ghz: the signal fades _a lot_ faster with distance. That's why you can't do long distances and that's why there is little or no interferences between two links.

At 400m, you can just align by sight and get a pretty good result. In fact, -55db for 400m is not a good signal. You should be able to get much better.

Especially since he says Wireless Wire (i.e. Wap60) and not Wireless Wire Dish (LHG60). To answer, no. I would not use Wireless Wire at that distance

lol Eliot you wrote " PtP W60G link." gr0mit wrote "Wireless Wires" so I m confused there is LHG60G and wAP-60G
I know I know Mikrotik stupid names everything begins with Wireless Wires Fiber Optic UP PoE 4km also 200m+ so + is like 100m or 500m you figure it out.

So does this mean if I have it @ 200m or 20m I should see -20db? When I was testing in our office (we can get up to 25m) I was only ever able to get them to -49db, at 426m I am sitting around -58db on the 58320 frequency.

With the dish (LHG60G)? Should probably be around -30/-35. At 400m, it should be around -45 and at 1km, -55 (with channel 4). With channel 1, it's probably going to drop to -55 for 400m and -65 for 1km.

Problem is with beamforming, but there's tun of tutorials on internet to show you how to do it if you know how to google. As for my PtP link I didn't do beamforming and link is stable, that's why I've post my experience since this Topic is named "LHG 60G experience".
If Gromit wanted to use wAP 60 he should ask in appropriate topic.

So my whole point is. In my "experience" you shouldn't need to do beamforming at 400m link and you should be totaly fine even in rainstorm. And as I've already said, everything in networking depends on you needs. If you need maximum performance you should allign and set-up your link properly, but if you don't need more than 600Mbit/s and you prefer low latency and no interference you should be fine.

I've been running down through the thread, where is the disable beam forming at? I will try to align without it, I am guessing we have been impatient with the alignment process, or beamforming is causing us to have a poorly aligned link and correcting it for us. its the set tx-sector=0 ?

Re: LHG 60G experience

Wed Nov 07, 2018 12:56 pm

Hi Ladys and Gentlemen,

we are new to Mikrotik Devices and also new to 60GHz Links - so please be gracious to us, if we did a major mistake...

To give you a short info who we are and what we are doing:
We are the IT of a german Civic Administration. Most of time we need short connections around 500-1000m for our numerous outstations to connect for example City Halls, Libraries or Daycare Facilities for Childrens with the civic network. Till now we use a mix of 40GHz licensed (Connection between our 2 Town Halls and some Distribution Points), 23GHz licensed (Town Hall Backup) and 5GHz free equipment to connect our outstations.

As we are always willing to learn more and experiment with less expensive stuff we tried out a couple of LHG 60G that we installed 2 weeks ago for a link between one Town Hall and Waterworks. This is the Result we are getting - Station:
Signal: 80
MCS: 8
PHY-Rate: 2.3Gbps
RSSI: -69dB
TX Sector: 32
RX Sector: 96
Distance: 905.36m

Peer:
Signal: 55
MCS: 6
PHY-Rate: 1540 Mbps
RSSI: -69dB
TX Sector: 52
RX Sector: 96
Distance: 905.36m (would be surprising if it would differ from stations distance)

LoS-Test is good - no Trees, Houses or anything else between both points that should reach or effect the fresnel zone.

Do you have any ideas what is wrong here? We are getting ~90 Mbps/90 Mbps with Bandwith Test for Tx/Rx 10s Average.
We tried the different frequencies as mentioned here in this thread with winbox, but that didn't change anything. The connection seems to be bad with all frequencies and settings. Best for us is 58320

We also tried to test the native data throughput and was reaching 8MB/s as a max. So the data from this test seem to be real.

For the moment based on this data we would try to calibrate the Peer again - any other idea? Faulty device maybe?
As many of you say don't calibrate on behalf of RSSI - what should the Tx / Rx Sector be if we use them for calibration?

Regards

Daniel

Yes, bandwidth test is the first mistake :)
Have you tried actual traffic through the link?
Also, you running latest RouterOS on both units?
No answer to your question? How to write posts

You alignment is bad @1000-the RSSI 'd be aorund -53 or less. Try this kit to have a "professional" allignment bracket for LHG 60 http://www.cdr.pl/p6418,uchwyt-precyzyj ... adkit.html

We use LHG-60G on link ~900 meters. We have 1 gbit/sec in duplex mode bandwith-test. We try to establish link in 1.5km - fail.
what is dublex mode ? on LHG 60 you have choice for full dublex and half-dublex ?

Thanks for fast replys. You are deploying that tool for us, so you really should expect us to use it :lol: 8)
But as we know from other installations and devices that can test there throughput we never expect such tests to be real. So yeah, we tried actual traffic - maybe it was a misspoke here. We tested file transfer with a folder and round about 70 GB of Files with different sizes. Also we had iperf running which was also match with our tested data.

Totally forgot about to mention the version we are using: We run them with 6.43.4

I think we will have a look on our alignment again.

@server8
Is this a set of 2 or do we need to order it twice?

:oops:
I am a bit depressed - should have checked that myself.
Your expectation is right - Peers interface is however set to 100MBit/s. We'll investigate that when we check alignment...

I tried to use align option for alignment the links and update devices to beta version and it's seems broken... when I use align in cli mode rssi and signal change so rapid for ex 50- to -58 but so quick when use monitor its better. which one should I use ?

and what should I check first while align, tx-sector-info ? or RSSI ? or Signal ? :) too much option on it

Thanks

I don't use align for same reason - to fast and all-over-the-place update of data. Use normal monitor, but be patient. Move lhg slightly and then wait couple of seconds. I look only at RSSI...

Hi,

To all who have aligment problems!

Use this method and You never miss:

https://www.aliexpress.com/item/10000m- ... a4f512def4

1. Install just the LHG mount

2. Allign the mount with the laser

3. Install the dish to the mount.

4. Enjoy


Kind Regards

Aleksander

I worked on it too much to set :) I should work more you mean :) there are 2 LHG 60 on same tower but diffrend frequency, and one of them bridge mode and other client. is that situation make problem ? or should I caution on something ?

Thanks.

Re: LHG 60G experience

Hi guys, here are my results:

[admin @ AP]> int w60g monitor wlan60-1
connected: yes

[admin @ CYBERA]>

[admin @ SM]> int w60g monitor wlan60-1

rssi: -61
tx-sector: 13
tx-sector-info: right 0.6 degrees, down 1 degrees
distance: 2312.31m
tx-packet-error-rate: 0%

I liked the devices, but borgadas complain about fastening, as it is not very convenient.

There is also a big problem with software, on a stable 6.43.4 RSSI 64/68 was.
Probel upgrade-firmware beta: 6.44beta28 became RSSI 60/59
antenna pointing is very difficult, as the signal is updated with a delay.

My 2.6Km link does not want to link up. I'm using 64800 as not totally sure about legalities of 66Ghz in the UK yet. Little bit gutted as I expected at least something.

Apparently you do not direct the antenna. We previously worked with SIKLU so there is experience.

The main thing that would be direct visibility and accurate guidance. There are more people who have if the link and 4 km.

15M & 20M AGL at the 2 locations with very clear LOS. The Siklu links we have were easier than this!

Hi Steve,
Just send me the airline tickets and I will be glad to stand at one end of the connection to move things around. I am really lucky ;-)
On the other hand the fetid vapours of intoxicated Brits (on warm beer) may be a cloud to dense for your traffic ;-PP
I'd rather manage rats than software. Follow my advice at your own risk! (Sob & mkx forced me to write that!)

We should be getting up to 70 GHz in the UK , will the hardware support this i wonder? There is no "country code" option at the moment. 70GHz would be nice to use.

Yes after two months first rain in Serbia but here it is light rain with little snow. With this new version is working great on my short link 240 and 340m with wAP i LHG no disconnect.
We will see on heavy rain or show when is happens, backup link is ready ;).

Hi!

Today, I tried to install my first LHG 60G - with not so much success...

399m, perfect LOS. No rain.
RSSI is only -48 NO MATTER, if it is really centered or no, NO matter which frequency. I could not get more than -48.

BUT: rx-phy-rate is changing all the time from 2.3 Gbps to lower values to "connected: no". tx-packet-error-rate is showing crazy values (between 0 and 2000%).
I am using RouterOS 6.44beta28

Can you give me a hint, what was my fault?

EDIT: Just disabled beamforming (tx-sector=36). Now, the link is stable at 2.3 Gbps phys, but still at -47 to -50db. Did you ever see better RSSIs?

Thank you
Stril

Hi!
I am already using this kit on both sides, but its really strange:

I can see a wide window, where RSSI is about -50db! I just cannot get more than -40 to -50 - no matter if "perfectly alligned" or not.

One more, strange thing:
With 6.43.4, PHY-RATE is sometimes going down, IF there is no traffic on the link. If I start the bandwidth-tester, phys-rate is stable at 2.3 Gbps. Without traffic, it is fluctuating...

With the dish (LHG60G)? Should probably be around -30/-35. At 400m, it should be around -45 and at 1km, -55 (with channel 4). With channel 1, it's probably going to drop to -55 for 400m and -65 for 1km.
I found that post and thought, -50db is not good for 400m...
If -50db is o.k.: Do you have any idea, why I do not get a stable tx-phy-rate, although RSSI is good? I tried different channels, beta-firmware and stable-firmware, with and without beam-forming.

I am also confused, that RSSI is the same - no matter, if I align the antenna to center or some degrees left/right and that it is not very stable. It goes up and down all the time for +- 2-3 db

You need to know that LHG60 has an Antenna array not only one,
So there Are more positions to get max RSSI

The fluctuation you see on data rate , you see the same on all 802.11ac Radios from MT if you not use the Link.

Those values were based on theoretical values for another device and adjusted to LHG based on real life experience. If you have more than -50dB, that's fine. The line won't start to drop before around -70dB so that's plenty margin.

LHG have beam forming so they don't need to be exactly aligned. Also, during the beam forming, values are going to change. You have to wait many seconds for the ligne to stabilize when you do alignment. If you reboot the devices, you will often not get the exact same values.

Hi!

But do you have any idea, why the phys-rate is not stable although RSSI is good?

It is best at 64800 MHz, but not perfect stable at 2.3 Gbps.
At lower frequencies, RSSI is still at -50, but phys-rate drops sometimes to 386 Mbps

I tried it with and without traffic. After some time of traffic, phys-rate is mostly 2.3 Gbps but not always. Do you see drops without traffic?

...and what about the error-rate? What do you see here, or are most of you using the stable firmware?

@tx-packet-error-rate:
I do not really understand, which is the cause for theses errors? I have a better RSSI on a short link, but still see up to 10% tx-packet-error-rate. Is somebody else here seeing that behaviour? BUT: the tx-packet-error-rate goes to 0-2%, if tx-sector=36 on the master-side.

RSSI is also 4db higher without beam-forming...

Thanks for the congratulations :)

Link was deployed today. It is too early to say anything about it, but 5GHz AC will be backup. I didn't had adequate equipment for test, and btest is useless these days. I need another day without wind to finalize aligning. For now only one test user is using/testing it.

BTW this link is a part of two p2p links to span over 6km. Few weeks ago we tried that distance but it didn't work. So, now we have 4332 metres plus 2679 metres.

So it is to early to give you guys some results.

Ali u svakom slucaju drzite mi palceve da sve proradi kako treba.

BR/Pozdrav...

As You can see, both links are working on 66.000! On the central location. antennas are almost back to back, and it looks like it doesn't bother them :) I tried shorter link at 64ghz, but connection was not stable. I assume that is misalignment related.

My humbly opinion is that oxygen absorption is an obstacle to build devices with bigger dish. I hope that I am wrong. But there is no obstacle to implement 5ghz backup in same device...

You don't need external radio. 5ghz is implemented in same cpu with 60ghz. So, only feed!

Well its just for testing purposes, nothing else. Its not even stable....i was just curious how far can it get. Usable distance with pair of LHGs is about 1800m at 66GHz or 1400m with 64,8GHz. Stable in rain about 50mm/h. But for now we need protective cover for whole LHG because the grid of LHG is nicely holding snow and kills every longer link.

As You can see, both links are working on 66.000! On the central location. antennas are almost back to back, and it looks like it doesn't bother them :) I tried shorter link at 64ghz, but connection was not stable. I assume that is misalignment related.
is better to use frequency: 66000 for long distance ? do you have any experience with your tests ?

Great info! I correct myself :) So, what is maximum theoretical distance for 64800?

Hello

A colleague tried to install the Wireless Wire Dish kit (RBLHGG-60ADKIT), from mainland to an island. Mounted at 3 and 6 meter height, 700 meter over a lake, clear sight and so forth.

Also tried a different kit, same results. Default configuration, but no connection at all. Kits works without problems if next to each other. (ROS within 6.43.*). Used a couple of hours trying to align them with no success at all.

0.7 km with 60 Ghz should give maximum 0.93 m radius on the freznel zone ?
(Freznel zone calculator / formula).

How accurate must the alignment be for a successfull link to take place?

Other than alignment issues what could the problem be?

I would expect to see contact/link after trying long enough, even just for a short while ?


Next try we'll keep these tips in mind:
- Better mounting kits and/or lasers
- Disable beamforming: /interface w60g set 0 tx-sector=36
- Using CLI alignment (quicker/too quick): /interface w60g align wlan60-1

from our experience, the most important thing is to put a good amount of traffic over the link during the alignment. If you don't, the readings are not updated fast enough. Even in alignment mode.

If You could try downgrade to 6.43rc17 and see if it helps, I stumbled on very similar situation and downgrade to rc17 works like a charm.
And there is few similar situation in my deployments that rc17 works with stable mcs8 when newer fw wont even connect.
So If You would confirm rc17 as a solution I wouldn't feel alone :)

Yup also using the latest beta. On two separate links of +-1800m and 2000m cannot even make a single link. Using 64800 and 66000. You would think after aiming for a while there would at least be a connection - a bad one at least.

Yes, You have to wait a little (a lot) for link to establish. Be patient. First, connect devices in lab conditions, and after that take them to the field. Be sure to use 64800 or 66000. Aiming of LHG is very critical since it has only 2°. That 2° is very different from 5GHz. 60GHz have instant cut-off when You misalign the link. Once again: be patient. And put some traffic between devices while aiming - it would help a little (thanks to ryny24 for the tip).

And one last thing - I am using latest beta (6.44beta28) on all of my 60ghz links...

Hi!

Aligning is a real pain compared to other 60G-devices... I was using two Bridgewave-Links which could be aligned with a multimeter - easy process.

The LHG 60G are crazy:

- Without alignment-mode:
It takes 5 minutes! until the signal gets stabilized! RSSI dances up and down within the first 300s. Then, it is getting stable.

- With alignment-mode:
Signal varies A LOT! I wrote a script that averages the RSSIs of the last 10s to be able to see anyhing...

- After every restart of the link, it shows another RSSI...

I am using the precision-bracket, which is expensive but GREAT, but as the signal is not stable, its hard to find the right position...

please check if scan-list on "station-bridge" device includes frequencies you are trying to use. Alignment needs to be very precise for connection to be established.

Upcoming Beta version (will be released today or tomorrow) will include rolling avg of RSSI value - "10s-average-rssi"

Hi!

Can you tell me, what kind of grounding you are using with the LHG60?

Option 1:
Use shielded patch-cable and a surge-protector like the UBNT ETH-SP-G2 to ground the patch-cord.

Option 2:
Add second cable to the antenna with grounding-cable

Option 3:
Option 1+2

Thank you for your hint!

Wherever I can I use second grounding cable in combination with Schrack outdoor s/ftp cable. Anyhow, for me grounding is a must - regardless what many others are telling.

Hi!

Do you see ANY updates on RSSI, when the link is running?
I had much fluctuation within the first 5 minutes, but then, I do not see ANY change - no matter if it's dry or wet.

Yes. I suppose there will be less gain, perhaps 6dB less, so I could suppose a reduction of 50% in distance, 1500m-> 750m. In 750m there is also less fading, so I could suppose that a link from wAP 60G and one or more LHG 60Gs over 500-800m could work at least the same than a 1500m link composed by two LHG 60Gs. Is it right?

Depends on needs for Link,

with WAP to WAP wo go to 100m
With WAP to LHG we go to 300m
With LHG to LHG we go to 600m
all this cases without Backup link, we saw no drops in rain with this distances, waiting for some snow.....

So, you divided distances by two? Why? Did you experienced a completely down link during rain over nominal distances (ex 200m wap to wap)? Or did you experienced only a reduction in Throughput? And what about wap to SXTsq lite 60?

I have SXTsq 60 here but not deployed, gain difference to WAP60 is unknown.

WAP with 150m we see downtime in hard Rain, also with LHG at 800m

Friends, I ask for advice.
It is necessary to make a link to 250m. Traffic is assumed not much, up to 100 Mbps. What is better to deliver, LHG-LHG, or LHG-WAP
It is required in 60G, because. 5GHz is very noisy.

The price in this case is not very important, because the difference is not big. I understand that if you put two directional antenna LHG, then accessibility will have to be 99.9999%
But what will be the availability if you put two WAP or WAP-LHG

WAP to WAP will drop every rain /snow
WAP to LHG will drop on heavy rain

We have seen snow is a killer for 60GHz. Even light snow fall killed our 1200m link completely.

For my links, falling snow was not issue at all. Only that sticky snow that got stuck on antenna is causing trouble. And of course that You need 5ghz backup for 60ghz link

My humbly opinion is that oxygen absorption is an obstacle to build devices with bigger dish. I hope that I am wrong. But there is no obstacle to implement 5ghz backup in same device...

For my links, falling snow was not issue at all. Only that sticky snow that got stuck on antenna is causing trouble. And of course that You need 5ghz backup for 60ghz link
Please, post printscreen Link LHG 60GHz of real +4000m

I can't find anything on a new R2 version. Do you have any more information? We run 5GHZ backup paths on every LHG60, but an integrated backup would be so much easier.

Please, Ask Mikrotik Directly about the more details
The new LHG 60GHz R2
Have a distance of about 6,000 metar and More...
MIKROTIK is in the testing phase of the new R2 version

there are people on the forum who know more details

The biggest change is in the antenna - the construction
RX and TX
Resistance to rain, snow ...
prices will be twice as expensive

So Mikrotik is making an "R2" (release 2?) version of the LHG-60 dish that will support up to 4,000 meter (2.5 mile)? Complete new design on dish, that allows higher gain and harder to align?

I wonder if its only backup failover, or you can agregate 2 links 60+5ghz at the same time for bigger throughput along for instant failover.

what do you expect more if you bond 5ghz+60ghz? anyway there is 1gbps ethernet port, i dont get your idea (:
my point, just to get ANY connection during bad weather, okay let it be at least 100mbps for snow fall or heavy rain, so the customers would not fuck up to red our phones :)

100 Mb/s is better than nothing :-)

In PtMP scenario with long link 5 Ghz backup (>500m) is an interesting option

What if you go a bit out of range or a little bad weather hits and u dont have 1gb anymore, like have 800mbit, 5ghz would push that 200mbit back giving you full 1gbs again, doesnt matter if u go over 1gbs combined 60+5ghz during ideal conditions which would saturate your gigabit ethernt port, its about quality of service and failover.

Thats one example, besides why not use both links at the same time?Instant fail-over without interruption, isnt that the general idea?

I see everybody suggesting a specific 3rd party precision alignment mount but nobody suggested the Mikrotik solidMount
https://mikrotik.com/product/solidmount

It does look proper for the job and it is actually half price from the 3rd party one. Has anybody got any experience with it? Is it any good?

Re: LHG 60G experience

Thu Jan 03, 2019 12:40 pm

I have 5 different PtP links that I would like to upgrade to 60GHz.

The distances are:

40m
160m
185m
460m
1280m

There is never any snow and heavy rains are rear. I was planning to use LHG60 wireless wire dish for all of them but somebody suggested that the dish would not be good for the 40m link and that I should possibly use the wAP60G for the short links.

What is the problem with using the LHG60 for shorter links? Oversaturation of the receivers? If so, can power be turned down? I would prefer to use the small beamwidth of th dish than the very wide beamwidth of the wAP60G if I can avoid it.

My only requirement for all these links is max throughput and as close to the quoted gigabit speed as possible.

Any suggestions from people with experience on these shorter distances?

Thank you in advance

No problem for the short one use a WAG60+WAG60, for the middle two use WAG60+LHG60 and for the last 2 use LHG60+LHG60

if the 5 links are on the same tower remember that 64800 MHz overlaps partially 66000 MHz so you have to separate LHGs in angle and distance.

Use higher channel for longer links

Thanks server8.

The question is why is it a problem to just use LHG60 for all of them? Do the LHG60s do not work over short distances? And what is their minimum distance?

I could not find this info on their specs.

The links are not on a tower but on a roof of the same building. I can have about 5 metres distance from on to the other if needed and they all look a t a different side except two

Hi, we have 3 different installations,
Fisrt- 1.183 mtrs. above 60 percent of signal where both sites are visible each other.
Second- 806 mtrs same conditions before, no more 80% of signal
Third- 679 mtrs same as before 80% of signal.

The best speed in TCP is 500Mb upload and donload in send/recive mode, with 80%, in 60% we are talking about 150 Mb in both directions at same time.

But we have a problem, at first group, with default configuration, and both 60G connected, do not ping response

What do I have to do for repair this? Please help me.

I think you can use LHG60 without no problem but the wag60 has beamforming antenna with a narrow beam, for the shorter link is easy to install and manage.

For the colocation you have to make some test there are no reports from other users with 5 x 60 ghz radio in the same site.

Please tell Mikrotik that they will do the test on LHG60, will be stable 8000 meters, no way man :P

Tests in Poland [weather,rain, snow]
LHG60 - LHG60 - max 700m-900m stable on 64800MHz at 1/1Gbps [snow, mainly the rime kill the antenna]
Dish 400 Feeder - Dish 400 Feeder - max 1500m stable on 64800MHz at 1/1Gbps
Dish 600 Feeder - Dish 600 Feeder - max 2500m stable on 64800MHz at 1/1Gbps, we tested 1738meters, rssi -60 so at -69 will be 3000m

In each country will be different; different conditions, different humidity, other damping etc.

Why do you use the feeder, now?
Your first setup was: LHG with alu dish AND cover. What's the advantage of the feeder?

Full Solution for electronic LHG60
* better beamforming, because the electronic is perfectly center of the dish without any deform
* is possible to make 5ghz backup
* have waterproof gland on the back of the antenna so you can easly dismount from the mast
* mainly made for PtP Links

Alu Dish 400 without the feeder is only a fast solution to help others cheap dismount the grid and mount the original triangle feeder. This helps to do better rssi and reach more meters in rain and snow, secure from the rime, is full hermetic with ABS Cover... Mainly made for PtMP links, but others use this solution also for PtP links.

Alu Dish will always better than original grid.
Alu dishes will always better also in 2,4 and 5ghz.

Differences between ROS 6.43.7 and beta50 are huge so we have a better solution, the rest will do the software from MT... If original LHG60 will have teoreticaly 1500 meters our solution will have x2 :)

No 66000 on that distance!!! Perfect signals etc but you must use 64800 or 58, not 66000.

You cannot use 66, because is only for >3000 meters...

This is standard ALU without the feeder, with the front cover the snow at this point not kill the antenna and the distance is 2x than original lhg.

Can you read at all my posts?????

Frequency: 64800, I write to you that YOU MUST CHANGE 66000 to 64800 on that distance on ALU dishes !!!!

ALU 400 works extremely great on 64800 up to 1500meters

So you are in wrong and you make the basic mistakes my friend :P

RSSI is not and never will be a determinant of the connection quality...

RSSI down to -65 is ideal...

We have at distance 2900meters RSSI -62 so? In this point of view only iperf or btest show us if our link is correct aligned.

.... But RSSI is the only way to determine the signal margin for bad weather. Right?

I cannot install the link while there is heavy rain and snow.

Did anybody else see smaller RSSIs with Alu dishes?

I do it again today
LHG60 Original VS ALU400mm

the same location
ALU 400 and LHG60

please,
other users to make a REAL test LHG60 Original VS ALU400mm

RSSI and MCS
LHG 60 ORIGINAL is better vs Alu400

I tried on all frequencies 58000 - 66000

You have alu dish 400 without the feeder...
No way to get poor signals with alu dish, alu dish is not the plastic grid, alu dish always be better than plastic, aluminium always be better than plastic grid! :P

As I wrote there is also fast upgrade that make stable link in rain and snow, mainly to protect from the Rime, to get better performance and stability, no RSSI... If original LHG60 do 700meters stable, with alu dishes is 1400, 2 x better distance...

Maybe U must off or use 36 beamforming? Do you know about that? :) No tx power at this time.

You can't just make a random aluminum dish and expect it to be better just because of material. There are calibrations done, specifically for the original grid. Antenna design is a precise science, not a form of metallurgy.

@Normis, anything solid is better than this grid, especially in weather conditions as in our north countries. I can't imagine what was You thinking designing this particular antenna. Lower windload but possible total death of link due to snow/water/ice cap? You have Dynadish project You could use to achieve much much better product. but You choose grid antenna. So it's not weird that lot of people trying to fix mistakes of Yours by adding covers, alu dish etc.
AND answer is YES anything of casted/forged aluminium will be better than plastic grid just in matter overall availibility of link/year
Do your product more wisely in next release PLEASE.

Indeed. Especially remember that the higher the frequency (hence, the shorter the wavelength) the most precision needed.

The only solution I imagine for the ice problems is heating and/or some water repellent treatment. There are specific PTFE based sprays for that. Or maybe something like silicone based lubricant.

I'm waiting for some snow here to try but in 50 years I've seen less than 5 serious snow events.

Best is to use the heat of the radio/board itself. We see problems with snow on the longer links even if it does not hang to the antenna. Seems to have more influence on 60GHz than rain.
