LTE e System Architecture Evolution (LTESAE)

Technical staff and Engineers involved in developing and managing next generation Mobile Networks.

Good knowledge of UMTS architectures and protocols.

Acquiring the skills needed for understanding and managing the LTE Access and Evolved Packet Core (EPC) Network. The course analyzes the Long Term Evolution (LTE) technology, network architecture and performance with focus on LTE Evolved Packet Core (EPC) and its interworking with the LTE access network.
