Hi Miktotik.

It it possible to link several LHG 60 with a MetroLinq 2.5G 60 Beamforming Sector? I believe your AP is great, but I can connect only 8 CPE's to each one.

WAP60G and LHG60G use the same Electronics, the same PCB, all the same.

if we put PCBA from WAP60G to LHG60G

we will get a range more 6000m
WAP60G TX = 21.67dB+ LHG DISH 42dB = 63.67dB WOW !!!

Sure. But it's been said multiple times my mikrotik that these devices are calibrated. So will it work?

Its not a big secret, everything u need to know is on internet https://fccid.io/ There are pictures from internal parts.too.
Putting pcb from wap to lhg60 wil not work properly because there are different tx-sector patterns on lhg and on wap. LHG sectors are from 1.4 for each side. For up/down is the same. But wap uses patterns from 22 degres on each side so i think it will not perform properly. It may works only with fixed tx-sector in the center. Also this modification will exceed EIRP limit for 60GHz band, thats why LHG60G has tx power "only" about 12dBm.

Doesnt works, max 1521 meters on ros 6.42.1, we had this link on two waps and two alu dishes... LHG60 is much better. If we get beamforming calibration with tx-power settinga we do this after that...In this time, no way man to use it > 1500m :D

Theory is theory, practic is practic :P

beamforming during heavy snowfall on auto mode. after reboot once it is rssi -51, once it is -65, and yet there is -70

Is possible to get option static MCS and set tx-power with set static beamforming? So will be 3 options to set...

Hello Guys,
here is short distance link and have small problems like disconnection, distance is 200meters here is result;
AP Side;
connected: yes
frequency: 60480
remote-address: XX
tx-mcs: 6
tx-phy-rate: 1540.0Mbps
signal: 60
rssi: -48
tx-sector: 40
tx-sector-info: left 1.4 degrees, up 0.6 degrees
distance: 200.81m
tx-packet-error-rate: 13%

Client Side;
connected: yes
frequency: 60480
remote-address: XX
tx-mcs: 8
tx-phy-rate: 2.3Gbps
signal: 80
rssi: -49
tx-sector: 45
tx-sector-info: right 0.6 degrees, up 0.6 degrees
distance: 200.81m
tx-packet-error-rate: 0%

we try alignment many times but this is best, why rssi not below -49... whats your suggestions for this distance ?

Signal is fine. is this PtP or PtMP setup? Is latest version used on both sides? Are devices mounted on fixed / stable pole?

hello antonsb,
its ptp and yes using lastest version on both sides but beta, mounted with stable pole with solid mount.

for 200 meters signal is not good for me, I was waiting better signal before install them :)

I have another installed ptp link on 910meters and rssi: -51 and signal is -80

thnx djvolt, now I'm going to test it also, distance was not so far that's why I could not think change frequency :) I believe that for long distance high frequency needed on 60GHz

Re: LHG 60G experience

Fri Feb 08, 2019 9:37 pm

I planned to use a lot of 60GHz devices, in point to multipoint setting, in short range wireless surveillance.
For this implementation I always use 12V battery backup power supply, so the voltage is typically 13,6V (mains present, battery full), but it could drop until 10V, in case of complete battery discharge (the ups system disconnects battery when it reaches 10V).
Of course the ethernet cable is very short in this application, max 5m of lenght.
So, as Mikrotik states a 12-57 V supply range for those devices (instead of tipical 10-30V), It seems that you give no tollerance in a 12V environnement, right?
But I made some tests, and I noticed that an LHG 60G will start with a minimum of 10,5V and will remain running until 8V, and it can also be rebooted (via winbox) @ 9V with success.
So, can I simple accept that the tolerance I noticed is useful?
Can I go on with my application?
Thanks

In short, I realized that the stable version is not very stable and good either.
First, it is not convenient to adjust on it, since strong signal delay.
Secondly, according to my observations, the link falls more often than on the beta version.

Maybe my observations are wrong.

Re: LHG 60G experience

Thu Feb 14, 2019 11:44 am

In short, I realized that the stable version is not very stable and good either.

Stable version is stable for most (older) RB devices. It is also stable for LHG 60G, but unfortunately that means "poorly performing" ... due to the fact that 60G products are new and current stable ROS version is only initial version with support for these devices. Development of new features (and major improvement of existing features) is done in beta series and thus it's expected to see best performance using those ROS versions.

Stable has actually two meanings when it comes to ROS:
  1. Functionality in certain version series is stable: no new functions get introduced, obsolete functions don't get removed, ... only certain functions get bug-fixed or improved (some might argue that they also get "improved")
  2. devices are running stable ... without and service degradations and/or disruptions. This is mostly affected by lack of bugs and feature changes. Sometimes stable performance and maximum performance can not be achieved at the same time and some parameters have to be tuned for high performance without sacrificing stability. Which is often a try-and-fail process which clearly can not be done in stable release code path, only in testing/beta.
The point #2 obviously is not the case when it comes to new product where development of features is still very much active. And performance of certain functions still needs to be fine-tuned and bugs eradicated.

So.... whats the LHG60 PTP distance record so far? I just put one in today that is 1.6 miles! I won't know until springtime how much rain will fade it. It's for a small micropop site we have that will have a 5Ghz UBNT AC fail-over. If this works, I'd like to install several WAP60G AP's to get 1Gb services to the neighborhood, and deploy at other sites.

So far, 2.3Gb capacity and 80 signal, 2521m.

Also it is SNOWING here HEAVY right now, doesn't seem to effect signal by even the slightest.

Anyone have any OID's I can create probes in the dude so I can now graph the PHY rate, RSSI, etc.?

The question is why it has been renamed and why you will not allow - instead of renaming only - experienced users to set up TX power, MCS, etc manually. You do not like experienced users ?? But that would mean something serious ...

Thanks for sharing winbox data, show the other side of the link please. Finally, somebody understood that the LHG60 parabolic beam had a harsh beam pattern, and for longer distances it had to slash up to one degree from the axis. In this situation, no automation is able to set the link to a maximum of 1.5km or more, but the installer should know the correct TX-sector (not the center). Mikrotik, please finally post the LHG60 emission diagrams, please!

should know the correct TX-sector (not the center). Mikrotik, please finally post the LHG60 emission diagrams, please!

Re: LHG 60G experience

Fri Feb 15, 2019 5:23 pm

Hi,

I have 4 different links using wAP60 for one of them and three links with LHG60 devices. I am using 6.43.8 on all of them and all links are stable with good performance even during rain (we do not get very heavy rains) there was no noticeable performance degradation and neither did the status of the devices show anything different. I have not used the align mode because it is not available on the 6.43.8 and I have only "aligned" them by eye, although I did use SolidMounts. However, I have noticed a strange pattern. On all of the links the master side shows Signal: 95 and all the slaves sides show Signal: 80.

Is it possible to bring the slave side to Signal: 95 as well or should I just ignore it? Is there a point to try to align them even better by using the beta version and align mode or for theses distances my results are good enough?

Also, another strange thing with the wAP60. The two devices are 37m apart. Across the road basically. Perfect line of sight. The devices show tx-sector-info: center on both and RSSI -49 on the Master but -60 on the Slave. How is this possible for such close distance?

Any thoughts or advice highly appreciated

I am attaching the screenshots from the terminals below:

Reboot all devices and you will see another values.. strange but result of special auto mode built in...

Thank you komenski. You are right. It was confirmed by Mikrotik support. The reply I got was


"currently signal stats may not update due to previously fixed stability issues.
Stats will only update in case of beamforming event - we will fix this inupcoming versions."

Do you get the same on the beta version or is it fixed there?

Not fixed yet in beta. Statistics work as a roulette. After turning on the device, it will test all possible TX-sector variants, TX-power, MCS, etc., and stop in one of many possible variants. Criteria not known, known only by croupier ..

So practically speaking the stats screenshots that every single person posted in here during dry weather, rain and snow are not reflecting reality and are therefore meaningless?

Does the situation change when using the align mode available in the beta version?

If alignment by led lights is basically not working and stats do not really reflect reality how is someone supposed to properly install and evaluate the petformance of their links?

Sporadic iperf throughput tests is not a really practical way to align or evaluate how weather affects a link.

I am puzzled

If you make the alignment using the align command you will find the best signal, beamforming makes some tests in the first 2-3 mins so it's normal that values changes but after the monitor command shows the right valus from >6.44RCbeta61

Perused every entry here, and I would surmize that this would not be a good solution for an installation (2km) where only one site can have a fixed permanent antenna (not used in winter) and the other end will have to be a temporary setup approx 4-5 times per year. In other words, it would have to be aligned by not professionals and not take to long to provide support connectivity for sporting events.
(probably need a generator as well for power at the temp site). Assuming fixed pole of some sort or wooden structure and then attach mount (nice MT one) and antenna and align.
Thoughts, not sold on 60GHz but thought it would be best, but if other solutions are solid!!!
I'd rather manage rats than software. Follow my advice at your own risk! (Sob & mkx forced me to write that!)
