Course Overview

Course in a Nutshell

This is the second in our series of courses on LTE aimed at technical audiences.  The first one, LTE/SAE: A Technology Overview, is a recommended prerequisite.

This course provides detailed information on the signaling layers in the LTE air interfaces including the channel structures and the mapping up to the physical layer.


Customize It!

  • For those with good wireless technologies background but without exposure to WCDMA/HSPA, we can cover the prerequisite material upfront by extending the course to five days.
  • We can tailor the course to focus on the technology aspects most pertinent to your audience, whether radio/core network engineers, application/device developers, or other.
  • Add a workshop day at the end of the course, for a total of four days, for a deep dive into the transmission network IP backbone issues.


Audience / Prerequisites

Aimed At

Technical audiences with prior knowledge of WCDMA, HSDPA/HSUPA, and an overview of LTE.



  • “Very good information. Very visual; easy to understand complex scenarios. Instructor really knew what he was talking about.” – Benjamin Magana Salazar, RF-OPS Coordinator, Nextel
  • “The instructor knows a lot about the technology, platform, and messages. The course is very interactive. Very easy to understand.” – Carlos Alberto Guadarrama Molina, NOC PS Core Back Office, Nextel
