Course Overview

Course in a Nutshell

This course undertakes an in-depth study of the LTE performance and optimization procedures. We begin with a review of the physical air interface and LTE eNodeB KPI’s. The LTE accessibility KPI’s, including a review of the 3GPP functionality procedures regarding accessibility, are studied next. This is followed by a discussion of the retainability KPI’s and handover overview. The course ends with an examination of the integrity KPI’s concerning throughput and delay, coordinated with appropriate cell planning tuning and optimization.

 

Customize It!

  • If some of your participants lack the necessary WCDMA/LTE background, we can teach an extended five-day course that includes WCDMA principles, LTE overview, and LTE air interface techniques.
  • Add a workshop day at the end of the course, for a total of five days, for a deeper dive into capacity planning optimization and cell coverage corrections/optimization
