The training starts with an overview of new network elements, radio additions and features for LTE-M and NB-IoT operations. Then the significant part of the course describes some details of the radio interface layout, channels, procedures, changes to legacy LTE radio, etc. This is followed by mobility enhancements, power saving features and new core network procedures available for device communication.


General technical knowledge of the 3GPP-standardised mobile networks (and LTE in particular) is highly recommended. For required background knowledge, we strongly recommend Apis’ “LTE/EPC System Overview” course.
