Intended Audience
This workshop is primarily intended for RF and systems performance engineers involved in LTE design, performance, and optimization.
Objectives
After completing this course, the student will be able to:
■ Define the LTE RF KPIs and map them to RAN counters
■ Identify various LTE signaling events that map to success and failure operational counters
■ Identify the RF measurements that are key to coverage and interference
■ Analyze the measurements through post processing tools
■ Analyze UE logs for root cause analysis of successful and failure events
■ Map above events to operational counters and corresponding KPIs
■ Accessibility and RRC connection and bearer setup
■ Radio link failures and bearer drops
