MMTC and 5G

Building on the material covered in 5G System Engineering, this course focuses on the use of 5G to support the growing IoT ecosystem and in particular, the support for MMTC within 5G. As such, the course focuses on the modifications which have introduced in Release 15 and Release 16 of the 3GPP technical specifications in order to support the billions of low power devices covering an eclectic range of use cases. In particular, the evolution of NB-IoT and LTE-M will be discussed in light of the 5G system along with the role of the NEF in efficiently transferring small data packets across the network. Finally, a number of MMTC enhancements will be addressed including eDRX, Power Save Mode and the introduction of Early Data Transmission.
