Course Overview

Course in a Nutshell

The course begins with a review of the modulation schemes, RF propagation issues, performance enhancement techniques, and multipath mitigation methods.  This is followed by a discussion of the principle of OFDM, IEEE 802.16 physical layer, and WiMAX signalling.  The course concludes with a look at the network architecture and link budget calculations.


Customize It!

We can customize this course to suit the needs of audiences such as hardware designers, application developers, service designers, sales engineers, marketing/sales personnel, radio planners, and persons involved in defense and homeland security applications relating to WiMAX.


Audience / Prerequisites

Aimed At

This course is aimed at technical professionals who are familiar with 2G, 3G, and/or other 4G (such as LTE) wireless technologies and desire a quick overview of the WIMAX technology. For a more in-depth treatment of the topic, please consider WIMAX-C3DC, the three-day counterpart of this course.



Familiarity with 2G/3G technologies or LTE.


  • "Good basics and some in depth information on WIMAX technology. Gave me good foundation for WiMAX system design and better understanding of WIMAX performance, characteristics and vulnerabilities. It was specific to job, great materials. Great job! I liked the energy of the instructor." – US Navy
