WiMAX for Mobile Devices Training Course

WiMAX for Mobile Devices (2 days or 12 hours)

As mobile WiMAX continues to be developed, so too must the customer devices used to access the network. This course is designed to provide a thorough explanation of WiMAX networks from the perspective of the mobile device. As such, the mobile WiMAX network architecture will be highlighted, outlining the key processes and procedures which must take place in order to support mobility of the WiMAX terminal.
