Course Objectives

This training is an excellent choice for engineers who have already gained experience with previous generations of mobile technology and begun to work with the new 5G system. Training maintains an appropriate balance between the topics related to 5G CN, NG-RAN (radio part) and 5G based teleservices, giving the opportunity to understand the system as a whole. This training also provides required background knowledge needed to fully participate in more advanced training sessions focused on particular subsystem or network element issues.



The participants should have general technical telecommunications/computer science knowledge on a degree level. Knowledge about LTE is recommended.
