This 2-day course presents the overview of Machine-Type Communication (MTC) features for the Cellular Internet of Things (CIoT) as specified by 3GPP for 4G and 5G networks.

It describes enhancements for the radio and core network, new radio technologies like LTE-M and NB-IoT, and other related topics. The focus is on Massive IoT features, but other IoT deployment areas are also briefly described.

This course exists in a shorter version, IoT in 4G and 5G in an Hour.
