EG91EFCR06A06M4G connection on BAND20 with a CMW290

Hi Team,

We please need your help to understand the following issue :

We are using the EG91EFCR06A06M4G to test communication with a CMW290 on BAND20.
We assume that the EG91E is a CatM1 device so it needs the eMTC bundle license on the CMW290. Our CMW290 only has the MTC license but NOT the eMTC one.
So we are suspecting that this could be the reason why the EG91E can not connect on BAND20. Is our understanding correct ?

Now what is more confusing is that the same module can connect correctly and communicate on BAND 3, in the same environment.
Please note that we are doing all of our measurements in conducted mode in a farady box.
The EG91E is factory reset and band selection is automatic.

Can you please help understanding such behaviour ?

BR
Renaud.

Hi @Renaud_Consulting
Please use AT+QMBNCFG=“LIST” command to check whether row_mbn is selected. If not, you can manually select row_mbn to test.
