The training starts with a broad overview of IoT-related architectures, applications, network technologies, access methods, connection models, and so on, followed by discussion of issues and challenges for the mobile network operators providing connectivity for IoT applications. The major part of the course is used for description of solutions for machine-type communication introduced in the 3GPP system up to Release 15 (changes in the existing radio access network technologies, description of the new ones, and new core network features, nodes, and interfaces) with an insight into 5G work.


General technical knowledge of the GSM/GPRS/UMTS/HSPA/LTE networks is recommended. For required background knowledge, we strongly recommend Apis’ “3GPP Mobile Systems Overview” course and suggest various Apis’ radio and core network signalling courses.

Note: FoldOuts are not used in this training.
