What is Cellular IoT - info page information

[jarmo000]

Hello


I've seen few different versions of tables when comparing between LTE-M and NB-IoT, and some sources claim, that max speed of LTE-M is 1/1 mbps

And in your info page claims that LTE-M has speeds of 300/375 kbps, is this max speed of nRF91 or results of your studies?

In row "Range", What does "4x" and "7x" mean? Is this comparison to normal LTE cellular network?

This is the page, that i am referring to:

Thanks

Hello,

Thank you for contacting DevZone at NordicSemi.

few different versions of tables when comparing between LTE-M and NB-IoT, and some sources claim, that max speed of LTE-M is 1/1 mbps

Which sources you are referring to? What is meaning of max-speed? Do you mean data-rate?

There could be difference in usage of terms like data-rate and throughput.

And in your info page claims that LTE-M has speeds of 300/375 kbps, is this max speed of nRF91 or results of your studies?

LTE-M and NB-IoT are 3GPP standards, and the table show the throughput numbers for those standards. Our devices (like 9160) do comply with standards and regulations. 

Regarding the range: I show this slide from the video from the same page:

Which show (typical) range for both technologies.

These for example:

Could you explain, what is difference between data-rate and throughput?
