RUT955/956 2 mobile antennas ws 1 mobile antenna

[primokl]

Hello all,

We are using RUT955 and RUT956 devices with our system. We are using just 1 mobile LTE antenna (Buy %product-title% | Conrad Electronic) at the moment and we are connecting it to main mobile connector. I would like to know if this is not ok. Is it better option to use 2 antennas since there are 2 connectors in the device.
Thank you for ehlping us.

Regards,
Klemen

Hello,

It is recommended to have both mobile antennas attached to have the best performace and coverage. If, for some reason, you can only attach one mobile antenna, then the main mobile antenna connector should be used. You can find more information about the purpose of those antennas and SMA connectors here.

Kind Regards,

Ok, thank you for that info.
Is there any limitations about minimum distance between 2 antennas?

Hello again. I have situation in NL. We have 2 routers 150m apart, facing in same diraction. System with RUT955 is wokring ok (normal mobile speed) but system with RUT956 is wotking slow (very slow mobile data speed). Both routers have the same mobile provider. Only difference i noticed is LTE band that they are connected to at the same tower.
Do you think the issue could be in router version or anytheing else?

Thanks for info.

Hello,

First, I would suggest updating both devices to the latest firmware versions.

Secondly, it is possible that the devices chose different bands, and thus, one of the devices is slower than the other. After updating the devices, check what frequency bands are used. If you see that one of the devices provides better speeds, you can lock the other device to that band as well. This can be done in Network → Mobile → Band selection.

Also, ensure that software flow offloading is enabled in Network → Firewall.

Let me know how it goes.

Kind Regards,

Great, thank you for information. I will be on site in monday. We will change SIM cards for different provider, than we will see about performance. Is there any logs for which band was used or when system change LTE band?
