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.

4G to 5G migration strategies

The evolution from 4G to 5G can vary depending on an MNO’s existing network status and strategy. First, remember that the control plane and UE signaling are managed by the master node, the eNB in NSA architecture with Option 3, while it is managed by the gNB in SA mode with Option 2. Since 5G coverage is very limited in the initial stage of 5G rollouts, the control plane is managed by eNBs with nationwide 4G coverage, and as the 5G coverage expands, the control plane can then be managed by gNBs. So, this is the essential consideration behind the 4G to 5G transition and migration strategy from an MNO’s perspective:

Before introducing 5G, we assume that an MNO has an existing 4G network, covered by Option 1, which comprises an eNB and EPC. As discussed previously, Option 3 can be quickly deployed by upgrading the existing 4G nodes and deploying 5G gNBs, so the...
