WiMax RF Planning

Course Duration

5-day instructor-led training


Course Objectives
The goal of this course is to present details and up-to-date information on both Fixed and Mobile WiMAX technology and the corresponding family of IEEE 802.16 standards. The focus is on the WiMAX radio planning and deployment. The participants will learn the features of the technology that are relevant for system performance, planning and deployment. Furthermore, the participants will learn about performance enhancement and optimization techniques.


Course Overview

This a 5-day course focusing on the WiMAX radio planning and deployment. We will address the following topics.

  • Differences between Fixed and Mobile WiMAX technology will be examined. The related layer 1 and 2 protocol functions are dealt with in great detail.
  • Relevant radio propagation and physical layer characteristics, in different deployment scenarios will be presented.
  • Radio planning case studies will be presented.
  • WiMAX deployment and roll out strategies will be examined.
  • Advanced techniques and their performance will be discussed (beamforming, space-time coding, MIMO, different handover schemes).
  • Practical numerical analysis will be followed by testing.


Key Benefits

The participants will gain a detailed end-to-end knowledge of the WiMAX technology, and the corresponding radio planning and deployment issues. Furthermore, they will be able to address real-world problems of the WiMAX deployment and future enhancements. Hands-on analysis and testing will be conducted.


Pre-Requisites for Participants

A strong knowledge of wireless communication systems is required. Preferential but not necessary experience with 2G or 3G radio planning and deployment.


Who Should Attend?
