Module Objectives:
Upon completion of this module, you should be able to:
1-Describe the E2E architecture of any WiMAX Network and its different
components
2 -List the different interfaces and distinguish between the legacy and
compliant one and the difference between them
3 -Explain the E2E scenarios for all the services provided by the WiMAX network
4 -Identify the QOS mechanisms used in the air interface and the Ip transport
network
5 -Identify the Security algorithms used in the whole network.
