Presentation
5G is arriving with new promises for connectivity, performance and geographical coverage. This course provides a broader understanding of the technical and practical prospects associated with the rollout of 5G compared with previous generations.
Objectives
The doors to 5G are about to open. This course aims to explain the limitations of previous 2G, 3G and 4G generations and the forthcoming 5G developments in services, architecture and the radio interface.
An overview of current 5G initiatives will be presented, together with the main technical developments likely to feature in the next generation.
Program
1) Introduction
