Cat-NB1, and 3GPP LTE release 14 Cat-NB1 and Cat-NB2 standards

[con2021]

Hi, I have 3 questions about the NBIOT standards please

1- How do we set which NBIOT service shall be used by our FW (3 Cat-NB1, 14 Cat-NB1, or Cat-NB2 standards)? 

2- Is that selectable by our modem (when the network supports it) or fully controlled by the network?

3- How can we know which standard is used/supported by the network?

Great, thanks. I am waiting for that.
