Mikrotik Netmetal 5SHP dual tuning

severinss · Thu Apr 24, 2025 4:05 pm

Hi, I'm using two Mikrotik Netmetal 5SHP dual in a sort of p2p connection, where the AP has a Mikrotik mANT15s antenna connected to it, and should serve a larger area with Wifi for a remote controlled machine, where the Wifi is being used for transmitting controls from the remote operator station, and real time video is being fed back to the operator. The machine has the same radio mounted to it, but with two Poynting Omni 705 antennas connected. Does anyone have any suggestions on how to tune this for better performance? The link works sort of great with plenty of throughput, however the CCQ are pretty bad, and I cannot simply figure out how to set the MCS correctly etc. I'm sure there are more parameters to tune than I'm aware of. The machine are working freely within the 90 degree horizontal azimuth of the sector antenna, and at distance from 50 to 500 meters and more. Adding both configs..

Goal: get least amount of packet loss with greatest coverage, signal strength and signal quality. Used for real time (<100ms glass to glass) video streaming for high performance operation. About 10mbps throughput required for video, so lets say 20mbit needed in Wifi link. Simple L2 setup, [Operator computer <-ETH-> Mikrotik Netmetal Access point <---WIFI---> Mikrotik Netmetal client <-ETH-> Remote machine computer]

Thanks

You have a few basic errors.
First, you are not using a (point-to-point) P2P system, but a point-to-machine P2M system. Their settings are slightly different. The main feature is that the signal level at (from) the mobile point is not stable, but fluctuates within large limits, the spread of at least 20 dB. Therefore, you can not disable modulation with low speeds and higher sensitivity.
Instead of changing the MSC you need to increase the buffer on the ports instead of the default 50 packets to 500 -1000.
Secondly, you tried to make a homemade MIMO antenna from 2 Poynting Omni 705, without qualification and special equipment to achieve an acceptable result will not be possible. You need to buy one MIMO antenna such as Poynting Omni 296.
Thirdly, enable 802.11 wireless transmission protocol, you do not need to use NV2.
Fourth, select the mode only AC
Fifth, disable protection from the hidden node you have only one hw-protection-mode=none.
Use the guard interval long.

Thanks for replying
1. Thanks for clearing up, since I'm a bit new to this and are only learning by doing.. or at least trying. What about going with a default setup for data rates and HT MCS? Where can I increase the buffer to 500-1000 packets?
2. I see. The reason I went for the dual omni 705 setup was to have some diversity in placement, since the machine we're speaking about is a CAT 325 excavator. The boom of the machine will sometimes get in the way of the antennas baseline - causing a glimpse of no Line of Sight from the single potential omni 296 antenna to the mANT sector antenna of the stationary AP. What will be ideal then? Is it possible to achieve some multi WAN bonding with e.g. a Mikrotik RB5009? I have this routerboard installed on the machine as a L2 switch for multiple devices, however I can assign another WAN port if this is feasible.
3. Alright
4. Alright
5. Alright
Any short explanation for the last three?

It is easier for me to connect via Anydesk than to teach you within the forum. Judging by your mistakes, your knowledge gaps are too big. For example, please explain why you set the output power to 40dBm. And what power can your device produce according to the specification?
On antennas in MIMO one antenna works in vertical polarization one in horizontal polarization. You connected two antennas in vertical polarization. Further the wavelength is within 5-6 cm so moving one antenna from the other by 1.5 cm radically changes the properties of the antennas. Therefore you need to replace the antenna.
For better performance you need to install 2-3 mANT15s around the working area.

You're correct - I'm only into the very first basics of setting up a simple connection etc.
Send me an email on severin@steer.no if you're willing to help me a little bit.
Thanks
