LTE RF & RAN Optimization And Troubleshooting Part-1

LTE RF & RAN Optimization and Troubleshooting Part-I Training is a comprehensive course dealing with the symptoms and causes of field performance issues in LTE Radio Networks.

This course provides insights into RF measurements related to coverage issues and interference to analyze the coverage holes and the overlapping regions in the LTE networks. It also addresses important topics related to LTE optimization like Key Performance Indicators (KPIs), Intra-frequency Handover analysis, review of I-RAT Handover and CSFB.

Initially, students analyze the Radio Network functionality and signaling message flows through UE logs. This then helps them to understand the use of various KPIs and performance reports, to optimize the LTE Radio Network.

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.

PRE-REQUISITES:

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

Prior to this training, we would recommend you to go through our LTE Technology Overview Training (if you are not well-versed with LTE basics).

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

DURATION: 40 hrs.

FEE: 30k
