This 2 day training session offers a profound introduction to LTE. Besides an overview of LTE basics - like the new air interface and network architecture - the main focus will be on principles and functional contexts in LTE. After the training the participant will have comprehensive knowledge of LTE basics and will be able to transfer this knowledge to his daily routine.

Target Group / Requirements

Employees working in technical departments with basic knowledge in GSM and/or UMTS who require an overview of LTE.
