Hello.
R11e-LTE6 - can I choose a mode of operation without frequency aggregation / BAND?
Is it possible to use only primary-band?
And turn off the use of ca-band?
Thx.

Simples ways is just setup only one band by

/interface lte set lte1 band=x ;
where x is your Band

Simples ways is just setup only one band

aggregation may be such:
primary-band: 7
ca-band: 7

or
primary-band: 3
ca-band: 3

IF your ISP accept that.
In EMEA\Poland I cannot connect that way even if ISP buy from gov two freq-width.

CA is receive automatically, you cannot disable it.

Write to support@mikrotik.com - maybe is some trik not mention in documentation, Luat AT Commands etc.

IF your ISP accept that.

I know all this.
Remember that in differ regions the assignating band to ISP is differ.
I not idea what is in your country.
If your ISP have in the same Band the two freq and allow to do 2CA to then in inside the same Band - then yes - you can connect to them and have the faster internet via agregate @Mhz in witdth upto @40Mhz max in Cat.6.

I wish you stability.
