Training Course Outline
Course Duration:
3 days
Training Course Description:
This 3-day course is designed as an introduction to the planning,
trouble shooting and operation of a WiMAX network. The course will
introduce the concepts of network planning with the use of the Planet
EV for WiMAX planning tool, plus it will cover possible routes for
troubleshooting and operating typically networks. It will be assumed
that the delegate will already have knowledge of or does not need
specific knowledge of the technologies involved in WiMAX or WiFi
procedures and concentrates on the planning and operation of the
network itself.
Who should attend?
Engineers, network planners, and support staff, with a basic
understanding of cellular or RF mobile networks. Plus basic WiMAX and
WiFi technologies.
Prerequisites:
Delegates should have a basic understanding of RF mobile networks, and
also exposure to WiMAX and/or WiFi technology.
