[LTE_412] LTE RF Optimization Certification Workshop (UE Based)

Printer-friendly PDF version

This workshop provides insights into the symptoms and possible causes of field performance issues in LTE radio networks using UE logs. RF measurements related to coverage and interference are discussed to analyze coverage holes and overlapping regions. Students analyze LTE signaling messages through UE logs and map them to success and failure events along with performing root cause analysis and gain an in-depth understanding of these signaling events to network performance. LTE RF optimization areas such as RRC connection setup, bearer drops, Intra-LTE and IRAT handover operation, downlink and uplink throughput are addressed This knowledge transfer is obtained through hands-on experience using UE based diagnostic tools and scanner tools.
Note: This workshop uses UE logs and scanner data for analysis and concludes with a certification assessment.

Required Equipment: PC laptop

Special Note: This is an advanced level course. Please DO NOT register for this course if you are not very familiar with LTE RAN Signaling.

Learning Objectives

After completing this workshop, 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 and analyze them through post processing tools
• Analyze UE logs for root cause analysis of successful and failure events and map these events to operational counters and corresponding KPIs
­ - Accessibility and RRC connection and bearer setup
­ - Intra LTE handovers and
­ - Inter-RAT handovers
­ - Radio link failures and bearer drops
­ - Downlink and uplink throughput

Intended Audience

This workshop is primarily intended for RF and systems performance engineers involved in LTE design, performance, and optimization.
