LHG 60G Low speed

Sat Nov 03, 2018 6:51 am

Hello friends, I have a problem with the new 60 Ghz antennas that mikrotik has taken, the LHG 60G model, which are 2 preconfigured antennas.

According to specifications, the maximum distance is 1km. I have 500m, it also says that the maximum synchronization is 2.5Ghz, I have them linked to 2.3Ghz.

Having said that, my problem is:

I can not pass more than tx = 410 Mbps and rx = 400 Mbps. If I do the test with tx and rx the speed it gives me is tx = 210 and rx = 180

attached alignment configuration (not to say that there is direct vision without problems)

Can you help me to know what the problem is?

PD- I have already tried the 3 frequencies that it brings.

Greetings and thanks (sorry for my English I'm very rusty))

How do you test the speed?

the last test I have done gives me separately tx = 598 and rx 587

If I do the test with both gives me tx = 199 / rx = 187

Do you know what it can be?

a greeting

test speed on different devices you are maxing out one core of the devices CPU and this is your bottleneck and not the wireless interface

If you want to make a decent measurement without using external devices you need to use the traffic generator instead of the speed test.

Example configuration in two w60g units:
[admin@w60-master] /tool traffic-generator> export 
# nov/05/2018 12:17:01 by RouterOS 6.44beta28
#
# model = RBwAPG-60ad
/tool traffic-generator port
add interface=wlan60-station-1 name=port0
/tool traffic-generator
set latency-distribution-max=10ms measure-out-of-order=yes
/tool traffic-generator packet-template
add interface=wlan60-station-1 ip-dst=192.168.1.152 ip-src=192.168.1.153 \
    name=pt0 udp-dst-port=100-300
/tool traffic-generator stream
add mbps=970 name=str0 packet-size=1500 tx-template=pt0


[admin@w60-slave] > tool traffic-generator export 
# nov/05/2018 12:17:28 by RouterOS 6.44beta28
#
# model = RBwAPG-60ad
/tool traffic-generator
set measure-out-of-order=yes
/tool traffic-generator packet-template
add ip-dst=192.168.1.153 ip-src=192.168.1.152 name=pt0 udp-dst-port=100-300
/tool traffic-generator stream
add mbps=970 name=str0 packet-size=1500 tx-template=pt0
(the master is 192.168.1.153 and the slave is 192.168.1.152).

Once ready, /tool traffic-generator start on both units. You can do a quick performance check using Webfig and looking at the throughput graph for the w60 interface (slave) and w60g station (master).

Running traffic generator like this on both units you will really be able to saturate the link properly. With speed test the CPUs in the units are the real limiting factor.
Of course you can also run iperf on two machines connected to the units.

Thank you very much, I did not know this method to measure the speed, but from now on I will do it that way.
I was much calmer when I saw the results of the test.
Tx = 994Mbs
Rx = 998Mbs

Attached screenshot of the dude where he measures the speed between the two links.


THANK YOU

Great :) These links are almost as good as a fiber.
