Re: LHG 60G experience

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?

Honzam how is 4173m link, any luck with the rain is it stable?
Thanks.
No you will need backup
What about 3km link, if I use 66Ghz do I need backup?

: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.

But how do you mount the laserpointer to the LHG-mount?

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 ;).

Each version of RouterOS includes a lot of changes, it would help us, if you write versions you are using.

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?

It was to cold today to play with link and finetune it. We are waiting for one day without wind to play with antenna aliment.

Wow! Congratulations!

@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.

Congratulations Gemb! How much time did You spent on aligning? I have another 5130 meters link and didn't want even to try, but Gemb give me something to think about :)

I can't understand why mikrotik/ignitenet don't have a 60cm version? Maybe it's a regulatory problem?

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...
