Overview of Mobile Network and LTE / Transmission Technologies

Course Objectives:

This training aims to introduce the idea of LTE IP transport network solutions to transmission design engineers.

LTE Transport Network should accommodate the traffic created by cellular coverage. Thus, the correct dimensioning of the Transport Network is critical from the QoS and capacity point of view.

Several technologies could be implemented, such as IP over ATM or IP over Ethernet. Mobile Packet Backbone Network solutions are described in detail and is supported by case studies to help transport designers understand the diverse techniques that can be deployed. Mastering these techniques, participants will learn how to contribute in end-­to-­end user throughput optimization.

Course Duration:

5-day instructor-led training.
