4G Fundamentals
Description
LTE is the best technology adopted as a 4G implementation. It is used by almost all mobile operators in the world today, and it will continue to exist for the next decade. This course intended to give an insight into the 4G LTE by introducing its the basic concepts and give a clear explanation of the key technologies and functions that made the power of LTE.
Objectifs
- Identify the LTE nodes and network architecture.
- Understand the basics of the Air interface.
- Understand why and how the data rate change in time and space.
- Describe the LTE core network protocol stack
- Explain how LTE manage mobility
Understand the interworking between LTE and 2G/3G
Prérequis
the course didn’t rely on specific background, though some networking and telecom fundaments are recommended.
