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.

Types of NSA networks

The NSA options include options 3, 3a, and 3x in addition to option 4 and option 7. In the introduction, we took the example of a deployment option known as option 3x. Let us further discuss the main features of this deployment option in detail:

  • All control plane signaling is handled by the eNB.
  • The eNB is connected to a 4G core for data and signaling.
  • There is data plane connectivity between both the gNB and EPC and the eNB and EPC. In this case, both the master nodeB and the EPC are capable of splitting the data traffic between the eNB and gNB.

The other two options of the same flavor are options 3 and 3a, as shown in the following diagrams:

The features of option 3 are as follows:

  • All control plane signaling is handled by the master eNB.
  • The eNB is connected to the EPC for data and signaling. The signaling for gNB is sent from the master eNB via the X2...
