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 EPS/LTE™ system. Training maintains an appropriate balance between the topics related to E-UTRAN (radio part), EPC (CN part) and LTE 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.

Target audience:

The course is intended for EPS/LTE technical staff and their management.

Duration:

3 days.
