Re: LHG 60G experience

@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 :-)

What are the commands to set 66000 and add 66000 in the scan list on the client and AP sides?
Still need these Chris?

Mikrotik 60Ghz CLI commands
STA
/interface w60g set wlan60-1 frequency-list=58320,60480,62640,64800,66000

AP
/interface w60g set wlan60-1 frequency=66000

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)

Dear users, what is Your real world bandwidth usage?
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

Thanks for reply, but I see it quite expensive bracket. And with my brick chimney 50m high, windload gives a lot of instability overall.
So i'm not sure if it will help.
1/As for now I see signal 90-105 and mcs 8 to 11, are higher mcs even possible?
2/And what about pps or tcp is this arm cpu capable of doing 1gbps TCP traffic? I've seen some iperf test to fill 950mbps of tcp but seen only tests.
3/Anybody use this gear in real world and achieves such bandwidth?

How did I miss that. Nice Blue nice alignment I was going to test 2000m next week.
With that signal moderate rain should not case any problems.

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?

Strange thing is the date it states its November and we still in October

This is the results:

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

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.

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.

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.
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.
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 ?

Honzam how is 4173m link, any luck with the rain is it stable?
Thanks.

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?
