LTE - SAE Protocols and Procedures
(3 days or 18 hours)

SAE is a 3GPP initiative to ensure that the evolution of the mobile core network and supporting service architecture enables optimal access to services as well as features such as seamless mobility, roaming and interworking. This course provides a detailed end to end discussion of the protocols, architecture and procedures that are currently being defined by the SAE and associated organizations. Those attending should have a good understanding of LTE operation ie mpirical’s LTE System Engineering course.

Who Should Attend

This course is designed for Support Engineers, Research and Development Staff and Technical Managers who need a detailed knowledge of the operation and architecture of LTE SAE Operation.

Pre - Learning

Pre-Learning is provided to prime those attending the instructor led phase. Each lesson is based on an interactive online format and should take about 30 minutes to complete. The pre-Learning lessons are:

  • Test of Understanding - Try the online check to see how much you know.
  • LTE Network Architecture.
  • LTE Operation.
  • Basics of LTE Mobility
