Course Overview

Course in a Nutshell

As 3G and 3xxG systems get deployed worldwide, the development of competitive technologies that promise additional capabilities and services at more attractive costs is also underway.  WiMAX is a major contender in this arena.

This course will help you build a solid understanding of the capabilities, strengths, and limitations of WiMAX, including Mobile WiMAX, as an alternative solution for broadband wireless services.  Following a brief regulatory and historical perspective, we will focus on the two biggest challenges faced by the mobile communications channel and how they are addressed in representative technologies.  We’ll discuss the pros and cons of the various solution approaches to the issues presented by WiMAX.  We’ll also discuss the optional implementation of OFDMA in conjunction with CDMA and the benefits/challenges that it presents.  This will pave the way for an intensive study of how WiMAX works and the details of its physical as well as MAC layers.  We will conclude the course with a detailed comparison of WIMAX vis-à-vis WiFi and the evolving 3G/4G technologies as well as some of the business issues related to the WiMAX deployment.  In short, you will learn all important aspects of WiMAX in sufficient depth to allow you to make sound engineering judgments.


Customize It!

We can customize this course to your job requirements, whether network design or optimization, technology evaluation or strategy, equipment or application design, marketing or sales, or operations support.  While the standard presentation of this course assumes an engineering or other technical background, versions of this course aimed at less technical audiences are also available. We perform most course customization at no added cost.
