Course Details
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 5G Interworking are all considered. In conclusion, the course focuses on voice services, with emphasis on both CSFB and VoLTE.

Philip Nugent
Mpirical Trainer
Phil heads up Mpirical’s technical development, advising on the latest technologies and assisting the Mpirical team with his wealth of both historical and current knowledge. Phil’s specialist area is the mobile radio and RAN space, originally focussing on 2G and 3G technologies but more recently, heavily embedded with 5G New Radio for both Mpirical and customer specific projects.
