EM12-G LTE

Tue Oct 12, 2021 10:43 am

Hello dear Mikrotik support and others.

I'm using EM12-G module with RBM11G

Firmware version: EM12GPAR01A21M4G

So, the problem is when EM12-G is working on the carrier aggregation for the 3 bands(B1+B3+B20) it is dropping connection time after time.
If EM12-G module is working only at 2CA bands B1+B20 everything is fine and there is not dropping connection.

So here is the raw data at moment when module is dropping connection

I'm understand that this problem is not with RBM11G and Mikrotik.
I'm tried Mikrotik device Chateau from the carrier operator LMT (Latvia) with EG18 module and there is no such problem it is working in 3CA mode with no disconnection.
