LTE RF & RAN Optimization and Troubleshooting Part-II Training is an extensive course which explains how to identify and troubleshoot abnormal LTE Radio network behavior. Also, it deals with all the possible determinant factors for this abnormal behavior of the network.

This course provides insights into LTE RF Optimization areas such as Downlink and Uplink Data Traffic Performance. It describes how statistic values can be aggregated from the existing network and evaluated for optimizing the network.

This LTE Optimization & Troubleshooting course further addresses various important concepts such as connection drop scenarios, methods of resolving call drops, identifying associated counters, idle mode performance, tracking area planning, paging etc. in detail.

This is an instructor-led training with the instructors having a minimum experience of 8-15 years in the Telecom domain. Also, our team of Telecom experts guides the trainees throughout the training duration, by discussing practical troubleshooting use-case scenarios and best possible practices to find and solve them.

This transfer of knowledge further takes place by providing hands-on experience to the trainees using UE-based tools. This further helps them in the retention of this experience.

Who should attend?

This advance Telecom training is best suited for Telecom professionals/RF Engineers working on LTE Radio Networks (having a minimum experience of 6 months- 1 year).

Primarily, engineers involved in RAN part of LTE networks benefit the most from this training. This extensive course provides them the opportunity to upgrade their knowledge, technical skills, salary and position in the Telecom Industry.


This is an advance level LTE course. Basic knowledge of LTE EPS like LTE Architecture, LTE Interfaces, signaling process etc. is required.

Prior to this training, we would recommend you to go through the following trainings offered at Apeksha Telecom:

  1. LTE Technology Overview Training (if you are not well-versed with LTE basics).
  2. LTE RF & RAN Optimization and Troubleshooting Part-I Training

Previous experience of GSM/UMTS radio network optimization would be useful but not essential.

DURATION: 40 hrs.

FEE: 30k
