It accounts for the evolution from the voice centric GSM (2G) via the data traffic of GPRS and UMTS (3G) to the all-IP architecture in LTE (4G) and IMS as used for VoLTE. The course also introduces IoT and 5G. All topics are presented in a comprehensive – yet easily understandable – way. Essential principles, procedures, subsystems, nodes and protocols are described. Basic traffic cases are used to demonstrate the function and architecture of the different systems.

Prerequisites

Technical education and/or at least one year of technical telecom experience is recommended.
