LTE System EngineeringCourse Description

With LTE now the cornerstone of global 4G services, this course provides an end to end view of a typical LTE deployment. As such, the architecture required for LTE, including the air interface and all of the key interfaces and protocols, is examined. The course then takes a “day in the life” approach to the LTE handset, detailing all of the typical activity an LTE handset undertakes as it interacts with the network; procedures such as Initial Attach, Bearer Establishment, Mobility and Interworking are all considered. In conclusion, the course focuses on voice services, with emphasis on both CSFB and VoLTE.
