 Course
Description:
This course is targeted at students who will be completing the
WiMAX Network Designer™ certification program, and who require a
refresher course on RF design. The one-day course, or its
equivalent, is a pre-requisite for the two-day course “RF Design
for WiMAX Networks”. If you are planning to complete the WiMAX
Network Designer™ certification exam, but have no recent
experience with RF design, we strongly recommend that you take
this course.
The course provides deep background and hands-on experience with
the RF propagation models that are used in all RF planning tools,
like those used for WiMAX network design. You’ll learn the
differences between various propagation models, and where each
model should be applied in your RF design process. You’ll learn
how to model foliage, terrain, buildings, and other obstructions
in a network design. You’ll prepare yourself for WiMAX-specific
network design, and you’ll learn the fundamentals of RF design
which are tested in the WiMAX Network Designer™ certification
exam.
The course is structured as 50% tutorial content, and 50% hands-on
exercises. Four spreadsheet tools are provided to enhance hands-on
experience, and you’ll have the experience of building an
additional spreadsheet in class to model the loss budget for a
link. Bring your laptop, or arrange in advance for DoceoTech to
provide one for you.
