5-day instructor-led training, 0900-1700

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 participants will learn the features of the technology and understand the differences between Fixed and Mobile WiMAX. Furthermore, the participants will learn about practical performance and deployment issues as well as about advanced techniques. Other alternative broadband wireless access (BWA) technologies will be examined (HSPA and LTE).

This is a 5-day course focusing on the WiMAX technology, its implications and distinguishing features versus the existing 2G and 3G systems. It will address the following topics:

The participants will gain a detailed end-to-end knowledge of the WiMAX Wireless Broadband Access technology, its benefits and potential pitfalls. Furthermore, they will be able to address real-world problems of the WiMAX deployment and future enhancements.

A basic knowledge of wireless communication systems will be required.

Technical managers that want to learn and understand the benefits and potential issues with Fixed and Mobile WiMAX. Infrastructure and terminal development and network deployment engineers that require a detailed knowledge of the WiMAX technology for its introduction or coexistence with 2G and 3G networks.
