Course Contents
The 5G System Overview provides a solid technical understanding of the 5G System as defined and standardized by 3GPP.
The course accounts for the various aspects of the 5G System (Radio Access Network, 5G Core), nodes / functions, interfaces / reference points, basic procedures and main architectural ideas. The course explains the key 5G features, like network slicing and edge computing, and how these are used to make the 5G System more efficient and flexible than earlier generations of 3GPP networks. The ITU 5G Use Cases (eMBB, URLLC and mMTC) are outlined in terms of services and technical aspects.
This course also examines the public safety services specified by 3GPP as key applications within the Mission Critical use case for 5G networks.
It begins by detailing the stringent Quality of Service requirements of critical communication services, followed by an analysis of 5G Standalone (SA) network capabilities designed to meet these demands. The 3GPP Mission Critical system architecture is introduced, along with the specific 5G SA features — in both the access and core domains — that enable low-latency, high-priority communication for fast-response verticals.
Target Audience
This course is intended for technical professionals that need to understand the 5G System from a technical perspective.
This course is intended for technical professionals involved in the design, deployment, or operation of mission critical and public safety communication systems for the law enforcement agencies, police forces, defence organisations, and contingency or disaster response agencies.
