5G Essentials

5G Essentials Course Details:

5G is the next-generation of mobile networks beyond the 4G LTE mobile networks existing today. The vision of 5G is becoming clearer and most experts say 5G will feature network speeds that are blazingly fast at 20 Gbps or higher and have low latency at mere milliseconds.

The entire 5G approach takes advantage of containers, virtualization, SDN and NFV. This section covers the design motivation and underlying technology of 5G service based architecture as well as new vocabulary terms you must learn. We will cover enough about 5G radio to understand the differences between 4G and 5G. All concepts will be explained with intuitive graphics. Each of the radio access methods explained below directly impacts specific components in the 5G core, so it is important to have a fundamental understanding of 5G radio prior to learning the 5G core. The 5G core is designed to support a service-based network architecture, so it looks very different than the 4G core. Nevertheless, we will assume that students are familiar with the 4G core, so this section will be taught in a fashion that constantly compares 5G core functions with an analogous 4G function. Each component in the 5G core will be covered from the perspective of what it is for, why it is there, and what it permits 5G to do that 4G could not. The goal is to more clearly see how the 5G accomplishes its goals by observing how it actually works.

Students will cover the design motivation and underlying technology of 5G service-based architecture as well as new vocabulary terms. Students will learn enough about 5G radio to understand the differences between 4G and 5G, and finally, take a look at the 5G core in action. Sample message flows of typical 5G processes are covered message by message.
