 Course
Description:
This course is targeted at students who are planning a WiMAX
network, and who need the skills to design a network, balancing
the requirements of service quality (including coverage and
performance) with minimum capital and operations cost. The course
teaches all Radio-Frequency (RF) design steps that an RF engineer
would consider for a WiMAX deployment. Each RF design task is
illustrated with practical examples, hands-on exercises and
application of a software RF-design tool. This is one of three
courses in a series which prepare students to take the WiMAX
Network Designer certification exam.
The course RF Design for WiMAX Networks is structured as 50%
tutorial content and 50% hands-on exercises. The tutorial modules
are followed by a network-design case study. Through a special
arrangement with EDX Wireless, a demonstration copy of the EDX
SignalPro software tool, including the Network Design Module, is
provided to each student, and used for in-class exercises. Youll
have the experience of designing the RF network for a sample
WiMAX-served community. Bring your laptop, or arrange in advance
for DoceoTech to provide one for you.
