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.

Initial access and beam management

mmWave operation is noteworthy. It opens frequency bands that were not accessible before – for example, Frequency Range 2 (FR2), as described in the first chapter. It brings more room for bigger bandwidth, which enables higher capacity and throughput. However, the transmission of mmWave is complicated. The path loss of mmWave due to free space propagation is much bigger than the typical LTE frequency. This culminates in limited cell coverage and cell size. To partially overcome this issue, directional beams are used on downlink transmission and uplink reception so that the path loss due to the free space propagation is partially compensated.

Directional transmissions enable new methods of multiplexing different users in the spatial domain, such as transmitting simultaneously to different directions instead of spatial multiplexing based on precoders, as with LTE. However, such directional transmissions mean that when connecting to the network...
