We were evaluating nRF9160 for IoT project. Wanted to know more about NB IoT
1: Does NB IoT support both 4G and 5G?
2: I have the following understanding , please correct me if I am wrong:
A: nRF9160 works on LTE-M and NB-IoT, LTE-M is only 4G and NB IoT is only 5G network
B: Only change in the firmware is required to operate in LTE-M or NB IoT and no change in hardware is necessary
