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
Delegates will be trained on state-of-the –art
knowledge regarding WiMAX BWA
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.
