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. The transmitter and receiver parameters and techniques, based on the 3GPP specifications, are then presented.  We conclude with a discussion of the physical layer procedures with emphasis on the channel quality and random access techniques.


Customize It!

  • If you 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 audiences with a good understanding of WCDMA/UMTS and prior exposure to LTE who wish to study the LTE air interface in depth.



The UMTS course, or equivalent knowledge/experience, is required; the LTE Overview is recommended.
