Re: LHG 60G experience

Tue Jan 15, 2019 1:17 pm

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.
Yes, problematic with the LHG though, I doubt the dish gets warm enogh.

Some time ago I read about problems they had in the Deep USA with LED traffic lights. Being more efficient than the typical tungsten incandescent lamps the things didn't get warm enough and it was frequent to have them covered in snow. They had to add a heating system for the Winter.

Oh and starling droppings could be a problem as well!

In Spain falconry is used to avoid such problems!

LEDs in your picture show that it's still connected
Still connected? Signal 40 and 700meters is still connected??? Where is 1500 meters???

Really? This is your answer Normis on WorldwIde forum? This alu dishes are absolutely perfect and perfect fits to your lhg grids so how dare you push the putty that it has no right to act since the dimensions and depth are identical? Hmm?

I have a Mikrotik's motto: "We sell plastic, electronics for free for everyone" :P


For the others:

Please do not use beamforming, please set 36 and use alu dishes :P

For alu dishes we have much better solutions: http://24.multimediahd.pl/pl/60ghz/111- ... -dish.html :P
With Cover is full hermetic :) We can also do heater inside for 24V :P

Eh Normis, I understand your frustration, but our product does not criticize your product, our product helps in the sale of your product like LHG60 etc :)

We have only upgrades for your products that improves your products, not whole products...

Like Mercedes and AMG, AMG helps to sell Mercedes so LHG60 is Mercedes but AMG is Alu Dish + Front Cover + feeder + electronic from whole LHG60, thats all :P

Instead of helping us, you will still be angry :{

I did a quick test link today between LHG60s and distance 167m. The link came up and was connected but I assume it needed further adjustment because the values were all low: MCS 3 and phy-rate 923mbps. RSSI -65.

The frequency was at 58Ghz and just for testing I changed it to 66000 manually on both sides. The link immediately dropped and never came back.

Does anybody know why the link disconnected because of the frequency change?

Re: LHG 60G experience

Tue Jan 15, 2019 11:27 pm

My 2nd question is what is the favorite/usual method of aligning the LHG60 dishes?

Do you install both dishes and try to point them as best you can to each other until they link? And then go to one side and adjust trying to maximise RSSI, then go to the other side and do the same and then go back on first dish and try to adjust even more and back and forth?

What is a tried and tested method of properly aligning these dishes?

Thank you

Hello aisme

This is that what I wrote some post ago, no way to use RSSI as determinant of connection quality :P Please use BTest to align correct link... If BTest show around 900Mbps in UDP or >350Mbps in TCP sesion the link is rock solid stable. You can also use align command, but BTest is the best solution at this moment... Please check always tx-sector information, perfect is "Center" mean 0



I have also this defect on ROS 6.43.7, 6.43.8 and beta50... After disconnect no chance to up the link :(

Aligning with BTest is a very bad idea for a short link in my opinion.

Bad aligned means: Gigabit on good weather, lower bandwidth on heavy rain.
Good alignment means: Always Gigabit
--> You want gigabit on all conditions.

What I do:
- Align "by sight" both sites (should be easy for 200m)
- Optimize RSSI on first site
- Optimize RSSI on second site
- Optimize RSSI on first site

Optimizing means:
- Align-mode
- Y-axis until best RSSI
- X-axis until best RSSI

I did that for a 400m link and it was quite easy.
You can make it easier, if you set tx-sector=36 (center) while you align.


On a 200m link, you should be far below -50dB (I think, about -46)

Yes of course: https://www.youtube.com/watch?time_cont ... 8On7sLnv_k

ROS: 6.42.1, Frequency 58GHz on two wAP60G. Do the same on original LHG :P I think only with off beamforming... Please off beamforming on our alu dishes and check stability.

Now we project the heater for our alu dishes, alu dish will be always warm <15 degree :) I think will be 24V, on the back will be waterproof gland with LAN port like in alu dishes Gen2 :)

Друзья, прошу помощи.

В роли AP выступает wAP 60G AP
В рои клиентов выступают Wireless Wire Dish (LHGG-60ad)

Расстояния до клиента1 327 м. (+-30м)
Расстояние до клиента2 500м.(+-30м)

Раз в несколько дней происходит отключение обоих клиентов, причем что странно, если зайти на интерфейс WAP interface w60g station print оба клиента присудствуют, но в логах видно что обе точки ушли из радио
Решается все перезагрузкой WAP

[admin@client1] > int w60g monitor wlan60-1
connected: yes
frequency: 64800
remote-address: 04:
tx-mcs: 8
tx-phy-rate: 2.3Gbps
signal: 80
rssi: -70
tx-sector: 50
tx-sector-info: left 0.6 degrees, up 1 degrees
distance: 359.8m

[admin@client2] > interface w60g monitor wlan60-1
connected: yes
frequency: 64800
remote-address: 04:
tx-mcs: 6
tx-phy-rate: 1540.0Mbps
signal: 60
rssi: -65
tx-sector: 52
tx-sector-info: right 0.2 degrees, up 1 degrees
distance: 540.69m

Прошивки везде 6.43.8

Вероятно у client2 слишком слабый сигнал, его попробуем улучшить, но почему выходит из радио и второй клиент, и почему они обратно самостоятельно не возвращаются.
Замечу что погодные условия не меняются, т.е. нет проливного дождя или снегопада.

Что можете посоветовать?

I've found out that a small amount of radioactivity is more effective. I am testing by fixing a piece of Tungsten-Thorium welding electrode. The beta particles emitted by the decay from Ra-228 to Ac-228 seem to help repel the water molecules from sticking to the surface.

Hi!

I just installed the Alu-dish+ABS-cover (that DJVolt offers) on one side of my LHG-Link.

RSSI seems to be a bit lower with Alu than with LHG-dish (+3dB) on my first test
 /interface w60g monitor 0
             connected: yes
             frequency: 64800
        remote-address: 24:18:1D:63:62:56
                tx-mcs: 8
           tx-phy-rate: 2.3Gbps
                signal: 85
                  rssi: -53
             tx-sector: 36
        tx-sector-info: center
              distance: 395.18m
  tx-packet-error-rate: 0%
--> seems to be ok (minimal more loss, but better protection against snow)

Some things about the Alu-Dish+ABS-cover:
- Alu-dish is very flexibel. When you adjust the screws, it bends.
- ABS-cover is not very precise. I hat to make the holes bigger to be able to use all screws.

Edit: One strange thing:
"Original" LHG works best with 64800 MHz in my setup - With Alu-dish, it is best without beam-forming and with a lower frequency!

I confirm, please off beamforming in newer versions or use 6.42.11 with smaller tx-power on that distances.

Up to 1000 meters 58GHz, up to 1500 meters 64800.

Update for ALU vs LHG dish:

The ALU dish has a strange behaviour: RSSI is good, Signal ist good, but MCS is unstable!

With LHG-dish, i see a stable MCS of 8 (PHY Rate: 2.3 Gbps). With the upgrade-kit, MCS goes up and down from 4 to 8.

Do you have any other idea, to make the LHG "snow-proof"?

I think it's highest time for Mikrotik to properly illuminate some essential features of his 60 GHz products. To date, we do not know the LHG and WAP60g exact radiation characteristics (even in frequency dependence), which is at least unusual and suggests that radiative patterns will not be so nice, but they should not be secret to users.
Further, I believe that this device would necessarily needed mode "align" which are temporarily turned off all functions counterproductive when setting up the connection (beamforming-center or off, constant TX power, MCS, etc ..). Many of the problems mentioned here are directly related to the incorrect setting of both sides of the link and consequent frustration by degraded climatic conditions (I do not think snow).

This is only 400meters, the power is to strange with alu dishes, without limit the power this link I think will be unstable. Please set beamforming to 36, if doesnt help please downgrade to last stable version like 6.42.11 and set tx-power to 5 :)

Original LHG is designed up to 600-800meters that should be still connected while weather conditions are bad...

For Mikrotik: please add option in software where we can set tx-power, MCS and set beamforming...

Its time to do all, because all used waps as sectors and lhg as stations, but it doesnt works properly...

Friends, go today, put the antennas on again, until they received such signals.

But noticed a strange behavior of the antennas. When hovering in the second antenna, the first one may fall off, although the signal on it is normal, this happens at that very moment when we aim the second antenna.

Such a feeling that there is some synchronization in the WAP.

Mikrotik has such a GREAT product with the LHG60G, but details are just too "cheap".

A "LHG-60G-PRO" with weather-proof, professional layout and better align-feature would open the doors to new customers for mikrotik. For short links, LHG-60G-PRO could be as good or better than UBNT AirFiber, etc.

Second is perfect on 64800. Puts full duplex 1/1G.

What would you like to get more on 400mm dishes without set correctly tx-power, MCS and tx-sector beamforming? Nothing else without this parameters.

You can only set tx-sector beamforming to 36 if you have Auto mode...

Explanation is the only one - LHG60g feed overradiates its parabolic antenna by most of frequencies. Probably the influence of the shape of the LHG60g cooler, which acts as the mouth of the waveguide - is to be modified for collar dishes.
In any case, must be set to a fixed tx-sector close to the center (27,28,35,36), auto-beamforming works counterproductive.

Hi!

There are just too many variables and modifying the hardware makes it any harder...

I have a 400m link. With lower frequencies, RSSI ist better than with high frequencies, BUT: MCS is unstable!

58GHz: RSSI=48, MCS is going up and down (on stable weather conditions)
64GHZ: RSSI=54, MCS stable on "8"

BUT: that happens with ALU-dish and LHG...

Perhaps, its a better idea to only add a cover and not to change the dish...

To short link for ALU :P No TX-POWER control... While will be available change this and set properly tx-sector and MCS the link will be extremely stable...

BUT:

Effect
effect of lack of power control, tx-sector and mcs together, but the link is extra stable...

Re: LHG 60G experience

Mon Jan 21, 2019 10:07 am

hy everyone,

we use a 60 GHz link in 387m (signal :95, rssi: -54, tx-phy-rate:2,3 Gbps) , it works great, but i do not find how to see "link downs" in dude. I can see a lot of things with snmp, only this parameter i not find.
Have anyone an oid code for this, or just tell me where can i print it out in terminal. Yes i know i can see it in winbox, but it would be great that i do not need always to log in after a heavy rain to see it.
thanks

Hello again!
Over the weekend, the linkage fell, this time he recovered himself, but the breaks are quite significant 10 minutes to 40 minutes.

On 400 meters? Its impossible or the new firmware is completely broken...

We use 6.42.11 and is extremely stable, also in this version is 66GHz available.

As Strill said I confirm, that alu dishes are stable without beamforming, tx-sector on 35 or 36 mean perfect "center" with proper alignment. No MCS falling, always show 8 and signal 80 on 2100meters.

+1 for channel sizes

100mhz or 200mhz steps will be better, at least 500mhz steps. not all need 1gb in ptp and in PTMP ( 8 online ) for sure :)

For all those who struggle these days with devices being snowed up - available solution of radome covering for harsh meteo conditions:

thats veeery good. seems that now somehow option for winter is available.

by the way, my thoughts WHY it accumulates snow. In order to accumulate ice - surface need to be cooled to LOWER temperature than abient static, then if we have humidity and a bit warming, we get ice on it. How to cool surface? easy - WIND, which blows through antenna cells. (: greetings from aerospace engineer :P

to simplify for who did not got about what it is written, imagine your deep cool fridge and result of the different in temperature you see inside the fridge box.

THEORETICALLY, if antenna to seal with PLASTIC bag from the back side, it should accumulate much less ice/snow

I finally received the Mikrotik Solidmount precision bases and for those wondering they are very well made indeed. They allow for precision movement in both X and Y axis. I wish they were included in the original package instead of their normal one. I have not used any of the 3rd party ones so I have no way of comparing them but for their purpose they are more than good enough.

When installing the LHG60 dishes I used Ubiquiti TouchCable terminated with Ubiquiti ToughConnectors and using the Ubiquiti surge arrestors. As per instructions this requires a short cable to connect the LHG60 to the surge arrestor. Then the surge arrestor connected to the long run of toughcable and close to source another surge arrestor and another short cable from the surge arrestor to the network switch. Field termination of the toughcable is a royal pain and I would like to minimise it at just the long cable run. Does any body know of a good source of outdoor rated, S/FTP, solid core, patch cords to use?

I've found a company in the US selling toughcable based patch cords terminated with toughconnectors but I am searcing something in Europe and it does not have to be made with Ubiquiti cable as long as the cable use includes a proper drain wire and not just the foil wrap.

Any information highly appreciated.

Finally got my link up! 64Ghz wasn't cutting it but when I've tried out 66Ghz we now have a link. There is still some more panning that needs to be done, still not quite the 4Km touted recently.

the answer to the big DISH for LHG 60 GHz

we decided not make larger dish for LHG 60. Because it brings high investment and we don't expect to much profit.
The gain could be theoretical aprox. 4 dB higher, but practical will be only 2 - 2,5 dB because of inaccuracy.
Second reason is: we are not able to got CE certification for that product.

I am sorry.

Hi

Is the align mode available on the latest stable version or only on the dev/testing versions?

Is this the correct syntax?
/interface w60g align wlan60-1

Because it does not work for me.

Also to do "proper" alignment, do I have to set tx-sector to 36 and beamforming off or is it done anyway by itself with the align mode?

Please forgive my ignorance but is there an official documentation describing the correct procedure properly or we just have to rely on each other's experiences and findings.

Thanks
