Who Should Attend?

This training is an ideal selection for engineers who have experience with previous generations of mobile technology and are beginning to work with the new 5G system. It maintains a proper balance among topics related to 5G CN, NG-RAN (the radio part), and 5G-based teleservices, offering participants the chance to understand the system comprehensively. Additionally, this training delivers the necessary background knowledge required to engage fully in more advanced training sessions that focus on specific subsystems or network element issues.

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.

Prerequisites

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

Training Structure

Four-day training divided into logical sessions.

Methodology

Instructor-led training.Lectures and multimedia presentations.
