RE: nRF9151 Cat-M and Cat-NB peak data rates

Thanks Priyanka,

It would be useful for this performance info to be in the chip datasheet rather than just in the academy training documents.

I have noticed that many IoT modems report different achievable data rates, and the LTE-CatM information I have seen suggests the standard supports higher data rates (e.g. Quectel BG95 and Quectel BG96 both support MTE-CatM, but with different possible data rates, and some summary documents support a maximum of 1mbps, presumably with higher power consumption and more air time).

Is the throughput on the nRF9151 a hardware limit? Or a limit of processing performance?

Regards,

Nathan Boyd.

Hi Nathan,

If you look at the DevAcademy: https://academy.nordicsemi.com/courses/cellular-iot-fundamentals/lessons/lesson-1-cellular-fundamentals/topic/lesson-1-lte-m-and-nb-iot/

You can see the following:

Is this what you were looking for?
