5G Introduction

5G (5th generation of mobile networks) represents the next step in the mobile telecommunication standards evolution, following its 4th generation (4G), reflecting IMT-Advanced requirement, and being represented by LTE/LTE-A and LTE-A pro releases. As in case of every previous generation of mobile network, 5G networks are expected to further extend and broaden the requirements, to make mobile services more attractive for end users, expanding the capabilities on top of the existing 4G networks. Depending on the use case, 5G networks are expected to offer peak speed of up to 1 Gbps, improved coverage, reduced latency, etc.

In terms of mobile services, 5G networks are expected to broaden the range of services, being collected in three main groups: Enhanced Mobile Broadband (eMBB), massive Machine Type Communication (mMTC) and Ultra-Reliable and Low Latency Communication (URLLC).

To achieve all the above requirements, network architecture, as well as radio access and spectrum availability have to be re-defined for 5G networks. This course presents motivation and path towards definition of key technologies for 5G.

Target audience

The course is intended for engineers and managers interested in mobile networks evolution towards 5G, with emphasis on the strategy planners and design engineers who need to understand 5G principles and basic design concepts, as well as challenges, which will be faced with the introduction of the 5G concepts in future networks.
