In Rel. 15, 3GPP defined the 5G standard. But as technology is evolving, there are meanwhile 2 new releases, Rel. 16&17, both downward compatible. They add new features to 5G and enhance existing features.

This course describes the current state of the development, explains the most important features and shows use cases that become viable. The course structure is modular, so you can choose the modules – except introduction and outlook - and their depth according to your interests.

Target Group / Prerequisites

Technicians and engineers of mobile radio networks who want the latest updates on 5G evolution. The participants should already know 5G and LTE.
