A communication module is the part of an IoT device that enables the device to connect to a network.

Cellular communication modules are separated into categories according to supported parameters and performance.

The module categories for LTE are labelled as follows:

NB-IoT network: Cat-NB1 and Cat-NB2

LTE-M network: Cat-M1 and Cat-M2

LTE (4G) network: Cat-1,2,3…

 

For NB-IoT, Telenor Norway supports Cat-NB1 with Cat-NB2 support in pipeline.

For LTE-M, Telenor Norway supports Cat-M1 with Cat-M2 support in pipeline.

The terminals also have to support LTE band 20 (800 MHz).
