Overview of this book

We are living in an era where ultra-fast internet speed is not a want, but a necessity. As applications continue to evolve, they demand a reliable network with low latency and high speed. With the widespread commercial adoption of driverless cars, robotic factory floors, and AR/VR-based immersive sporting events, speed and reliability are becoming more crucial than ever before. Fortunately, the power of 5G technology enables all this and much more. This book helps you understand the fundamental building blocks that enable 5G technology. You’ll explore the unique aspects that make 5G capable of meeting high-quality demands, including technologies that back 5G, enhancements in the air interface, and packet core, which come together to create a network with unparalleled performance. As you advance, you’ll discover how to design and implement both 5G macro and private networks, while also learning about the various design and deployment options available and which option is best suited for specific use cases. After that, you’ll check out the operational and maintenance aspects of such networks and how 5G works together with fixed wireline and satellite technologies. By the end of this book, you’ll understand the theoretical and practical aspects of 5G, enabling you to use it as a handbook to establish a 5G network.

High-level components

Multiple components come together to bring up a 5G network. In this section, we will learn about the high-level components that are a must in creating and operating a 5G network. 5G provides a lot of flexibility in the design of the network – we will also discuss the options as we go over each high-level component.

The access network

The access network comprises mobile base stations (gNB), which may be split up further functionally and physically into the following components – a Centralized Unit (CU), a Distributed Unit (DU), and a Radio Unit (RU). When there is a functional and physical split of various components of a base station, it is called a distributed architecture, simply because a single function of a gNB is now distributed among other smaller components.

This split is very useful to support lower-latency use cases and helps serve mobile edge computing use cases. Let us go over the components one by one:

  • In the CU, the...
