Introduction to 5G

Introduction to 5G Course by Tonex

Introduction to 5G is a 2-day training course covering next-generation of mobile networks beyond the 4G LTE mobile networks. Gain a working knowledge of 5G networking and communications standard. In this course, discover all you need to know to effectively plan, develop or use 5G in your applications. Understand the important concepts and requirements set forth by the 5G.

5G brings three new aspects to the table: bigger channels (to speed up data), lower latency (to be more responsive), and the ability to connect a lot more devices at once (for sensors and smart devices).

This is the first overall concept that’s important to understand about 5G architecture.

Next, you should know that 5G has never made a clean break with its predecessor, 4G. Due to the cost and time needed to build out a brand-new 5G infrastructure, carriers have had to create a sort of hybrid version of 5G that leans on 4G. This is sometimes referred to as non-standalone 5G.

While 4G has been necessary, it isn’t capable of producing all the highly touted benefits associated with 5G technology.

But that’s coming. Standalone (SA) 5G is almost here and very likely will arrive in 2021.

The third most important thing to understand about 5G is that the major carriers offer slightly different versions of 5G based on the spectrum holdings they have been allotted.

The 5G that just about everyone wants but is not that widely available yet is called mmWave high-band 5G. This is about 10x faster than 4G LTE with extremely low latency, which means individual messages are transmitted almost instantaneously. But you need to be standing really close to a tower or transmitter to get those speeds because mmWaves have penetration issues.

Most carriers are rolling out millimeter wave 5G in an extremely limited area, and focusing on public spaces like stadiums and arenas. Cities are also rolling out this super-fast 5G in highly dense areas, like downtowns, and some carriers are selling transceivers for home use – similar to how Wi-Fi works today.

Then there’s mid-band 5G, which is about 6x faster than LTE, but with a smaller footprint than low-band.

Low-band 5G is about 20% faster than 4G LTE.

An important term bandied about in the 5G arena is something called network slicing, a mechanism for creating logical networks with tailored capabilities for specific needs over one common physical platform. Instead of rolling out separate networks designed for specific services, 5G combines them into one physical network and “slices” it to fulfil various user needs.

Capabilities such as data speed, latency, security and mobility is defined to meet the particular demands of each use case. Further, each slice is logically separate so that no slice can interfere with the traffic in another slice.

As a result they appear as separate networks to the users. This has several desirable outcomes, for example the ability to contain a cyber-attack in one slice or preventing extraordinary scenarios, such as preventing a misbehaving sensor in one slice from affecting a critical service running in another slice.

The GSMA estimates that in combination with other enablers and capabilities, Network Slicing will permit operators to address a revenue opportunity worth $300 billion by 2025.

What You Will Learn

Participants will learn about 5G technology defined by 3GPP. With coverage of use cases, architecture, interfaces, protocols including business cases for Enhanced Mobile broadband (eMBB), Ultra-reliable low latency Communications and Massive IoT.

The goal of this practical course is to give the participant a strong and intuitive understanding of what 5G including 5G NR, 5G Core (5GC), Cloud RAN, MEC, slicing, Service Based Architecture (SBA), HTTP2/JSON, REST API, security, QoS, charging and policy.

5G is the 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.
