5G Fixed Wireless Access

This book explores the transformative potential of 5G technology in delivering high-speed broadband services through wireless means, particularly targeting underserved and rural areas. It covers several key topics including high-frequency spectrum bands, advanced transmission schemes, multi-connectivity, adaptive numerology, and Integrated Access and Backhaul (IAB). These elements are critical for enhancing network performance, increasing capacity, and reducing latency. The chapters cover topics such as the challenges associated with high-frequency spectrum bands above 24 GHz and how advanced technical solutions can address these issues. The efficiency of massive beamforming and Multiple-Input Multiple-Output (MIMO) technologies is explored in detail to demonstrate how they enable multiple user terminals to be served simultaneously on the same frequency resources. Multi-connectivity allows user equipment to connect to multiple network nodes simultaneously, improving reliability and performance. Adaptive numerology supports a flexible range of subcarrier spacing to cater to different services' quality requirements. IAB leverages the same spectrum for both access and backhaul, simplifying deployment and reducing costs by eliminating extensive fiber installations. In addition to these technical insights, this book addresses the broader issue of bridging the digital divide by making high-speed internet more accessible to remote areas. The relevance of these solutions is underscored by the growing global demand for reliable internet access. By leveraging 5G FWA technology, this book aims to solve the problem of digital inequality. This book is intended for professionals in telecommunications engineering, researchers focusing on broadband technologies, policymakers involved in digital infrastructure planning, and anyone interested in understanding 5G FWA's impact on future connectivity. It serves as a definitive guide to overcoming deployment challenges while ensuring that advancements in internet technology benefit a broader audience.
