This course provides an end-to-end overview of LTE RAN performance monitoring and optimization.

Network concepts and features are analysed against available network measurements and call traffic signalling flows, to infer the use of different counters and KPIs. Performance KPIs within this course are investigated on a vendor independent perspective, focusing on the concepts and applications. Alongside with the analysis of different KPIs classes and monitoring reports, this course also boosts a comprehensive approach to network troubleshooting and optimization tasks.

After attending this course, participants will understand how different KPIs are obtained, infer possible problems within the network and develop efficient approaches to solve them.

Who should attend?

  • 4G network planners
  • 4G optimizers
  • 4G quality control teams
