5G Essentials Training

This course features a mixture of lecture and hands-on training, making it possible to understand essential 5G concepts by allowing you to work directly with your own 5G network. You will follow a step-by-step approach to analyze the key components in a working 5G network. You will work directly with the UE, RAN, and core services. You will perform basic call flow analysis through demonstration and optional Wireshark downloads.

A hands-on approach to learning 5G is the best way to learn this new technology! When you successfully complete this course, you will possess a well-rounded, vendor-neutral, understanding of key components within the 5G network architecture and become fully empowered to take an active role in working with your 5G engineers. If you are an engineer and need a complete understanding of the 5G network, then strongly consider following up with an additional 2 days of Deploying 5G.

Understanding the RAN – You will learn about New Radio and study important differences between NR and LTE. You will extend the EN-DC core into the Radio Access network. You will diagram message flows within the 5G EN-DC network. You will learn practical applications for sub-gig to millimeter wave RF spectrum. You will study the core components of the 5G EN-DC network, also known as 5G Non-Stand Alone (5G NSA). Emphasis will be on the interoperability of architecture components and flow paths. Using network diagrams, you will plot the pathway of both user plane and control plane components.
