The course contains in-depth description of Cellular Internet of Things (CIoT) / Machine-Type Communications (MTC) features introduced gradually by 3GPP in LTE Releases 10-14.

Currently many MTC UE's are targeting low-end applications that can be handled adequately by GSM/GPRS. Owing to the low cost of these devices and good coverage of GSM/GPRS, there is very little motivation for MTC UE suppliers to use modules supporting the LTE radio interface. As more and more MTC UE's are deployed in the field, this naturally increases the reliance on GSM/GPRS networks. This will cost operators not only in terms of maintaining multiple RATs, but it will also prevent operators from reaping the maximum benefit out of their spectrum Given the likely high number of MTC UE's, the overall resource they will need for service provision may be correspondingly significant, and inefficiently assigned.

The LTE CIoT/MTC features aim at overcoming all of the problems outlined above by making LTE an attractive and effective network for handling IoT/MTC traffic for all interested parties, i.e.: operators, MTC UE suppliers and application owners.

Target audience:

The course is intended for experienced network engineers and E-UTRAN developers who are planning or have already worked on introducing LTE Cellular Internet of Things (CIoT).
