This workshop helps RAN and UE engineers analyze 5G SA and NSA based RAN operations using actual UE logs. Learners use the post processing tools to analyze 5G NR and LTE messages, parameters, and their impact to user experience. Instructor-led exercise sessions use signaling messages captured from live case studies (where available) to ensure the key learnings of this hands-on workshop are reinforced. Finally, learners present one of their log analysis to reinforce the learning of this workshop.

RAN and UE Performance engineers

After completing this course, the learner will be able to:
■ List the 5G RAN KPIs that impacts network performance
■ Identify the factors and events that impact 5G RAN KPIs
■ Analyze UE logs to derive performance issues related to Setup, Radio link, Throughput, Handover
■ Understand the failure signatures that result into poor performance
■ Analyze various scenarios of poor performance and present the findings
