Wimax for Broadband Access

Course Description
This course will provide the student with broad knowledge on current WiMAX and 802.16 standards, trends, issues and technologies. It compares BWA technologies to WiMAX and studies all issues regarding WiMAX as a Broadband Wireless Access Technology. Techno economics of WiMAX as a BWA solution is also included.

The session will include a demo project with WiMAX data and high-resolution GIS database.The database will allow the customers to experience planning, to do simple checks and to see the effect of factors (like the OFDM channel, diversity mechanism, clutter environment, propagation model etc.) on the resulted plan.

You will be using a product containing a comprehensive multi-technology and user-friendly radio planning and optimization tool that supports wireless operators during all stages of a network's lifetime - initial design, system deployment and operation. The product integrates sophisticated propagation models and cutting-edge optimization techniques to provide operators with planning recommendations for efficient network deployment, operation, and maintenance.

Duration: 4 days

Pre-requisite
Good knowledge of radio and network basics. Knowledge of IP protocol is required but not essential.

Key Benefits

Course Objectives
By the end of the course delegates will be able to:
- Explain what WiMAX is
- Describe the WiMAX principle of operation
- Describe the WiMAX architecture
- Be able to compare several BWA technologies over WiMAX for BWA service deployment.
