Course Overview

Course in a Nutshell

This course will undertake an in-depth study of the LTE air interface.  It will begin with a discussion of the radio channel environment and the related RF propagation issues to help you understand the problems that OFDM/MIMO solve. This is followed by a discussion of the modulation principles along with a detailed look at the LTE physical layer structure as it complements the modulation and MIMO channels. We  conclude with a discussion of the LTE idle mode functionality and physical layer procedures with emphasis on the channel quality and random access techniques. Also connected mode — with emphasis on scheduler, power control and Link Adaptation — is further analyzed, and user mobility cases are explicitly presented with emphasis on parameter configuration 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 and coverage calculations.
Audience / Prerequisites

Aimed At

Technical personnel with a good understanding of UMTS/WCDMA and some prior LTE background who wish to study LTE operations in depth.

 

Prerequisites

The UMTS course, or equivalent knowledge/experience, is a required prerequisite for this course. LTE overview is recommended but not required.
