LTE OPTIMIZATION FRAMEWORK ---BETA
Learn LTE Optimization Framework once. Use it for life in your career
OVERVIEW
This course reveals information and procedures associated
with LTE System Level Optimization and Performance Improvement. This course
takes a top to bottom approach in identifying Key Performance Indicators (KPIs)
for the LTE network. It will allow
you to become familiar with RAN side parameters and knowledge to create
KPI formulas to measure LTE Accessibility, Retainability, Integrity and Mobility
KPIs.

WHAT ARE THE REQUIREMENTS ?
Learners should have understanding of 4G LTE. The course is a mix of text format and video modules format to help you ace up and review concepts quickly. In order to get maximum benefit from this course. The pre-requisite for this course are that you need to be familiar with the following two courses.
- LTE Air Interface Foundations Explained
- LTE Configuration Parameters
You should be aware of how LTE air interface operates and how LTE RAN side is configured. What are the key configuration components in LTE? Having knowledge of this information will help you understand LTE Optimization framework better.
WHO IS THE TARGET AUDIENCE ?
The course is for ANYONE who is appearing for an interview in 4G LTE RF related role. This course is NOT for you if you do not have knowledge of LTE Air Interface operations and LTE configuration.
