Nighthawk M1. Only 3 Component Carriers (CC) supported and up to 4 in technical specs

Dear all.

We purchased a Nighthawk M1 (MR1100) a few months ago in Australia. We can see in the technical specifications of the product, that up to 4 Component Carriers are available. Also in below discussion said that a maximum of 5 component carriers can be aggregate:

But we have a Base Station Emulator (CMW500) and we realized that only can have up to 3 component carriers available for the M1. For example, following bands configuration is allowed: Band7 (4x4) + Band7 (4x4) + Band3 (2x2).

We have checked, in Downloads section, if there is a new firmware for the M1 but it is not any available (we get this message: Firmware/Software not available for this model)

We have two questions:

Q1. Could you confirm to us if 4 component carriers LTE-CarrierAggregation are available for the M1?

Q2. If answer to previous question is yes, could you tell us which bands configuration using 4 component carriers LTE-CA are allowed for the M1?

Thank you in advance,

Best Regards,
