LTE RF And RAN Optimization And Troubleshooting Part-2


LTE RF And RAN Optimization And Troubleshooting Part-2 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 analyse coverage holes and overlapping regions. Students analyse LTE signaling messages through UE logs and map them to success and failure events.

It describes how statistic values can be aggregated from the existing network and evaluated, and how the network can be optimized during the first stages of deployment, using dedicated examples to enhance the understanding. This course explains how to identify and troubleshoot abnormal network behavior and common failure causes.

LTE RF optimization areas such as downlink and uplink throughput analysis are also addressed in detail in this course. This knowledge is transferred to the students through hands-on experience using UE based diagnostic tools and scanner tools. Further, this course helps the students to develop a good understanding of the downlink and the uplink data traffic performance through various parameters such as CQI (Channel Quality Indicator) feedback, PMI closed loop feedback, scheduling algorithms in the UL and DL etc.
