VOICE OVER LTE TRAINING COURSE DESCRIPTION
This course provides a basic understanding of the 3G LTE Air Interface, SAE, as
well as Voice over LTE options and LTE Advanced features. Investigating the
standards for the EPS , formulated by the 3GPP standards body, the course will
set out to examine and explain the 4G environment from user equipment to border
gateway and beyond. This course will ensure the delegate has a grasp of all
aspects of the current global deployments, the next steps in upgrades and the
promise of things to come.
