The COVID-19 pandemic has been a pivotal moment for technological progress and has underscored the critical importance of home-based services. It particularly highlighted the vital need for dependable, high-speed broadband connections to facilitate remote work, maintain social connections, and enable online learning, demonstrating that broadband access (BBA) is essential for socio-economic development. As a result, the demand for robust, dependable, adaptable, and secure home broadband increased exponentially. Furthermore, the worldwide need for residential broadband is expected to stay strong after the pandemic, with projections indicating it will surpass 58 million subscribers by 2026. In 2020, during the pandemic, the global residential broadband market expanded to more than 1.1 billion subscribers, marking a 4% increase from the year before. The increasing growth rate is also due to the substantial rise in mobile data traffic demand and higher access rates over the past decade, driven by innovative services and applications such as financial trading, autonomous vehicle systems, and Internet-of-Things (IoT) devices. These services necessitate not just higher bandwidth, but also ultra-low latency, exceptional reliability, minimal energy consumption, and massive connection capacity. Consequently, telecommunication operators should reassess their access infrastructure and improve their management practices to achieve better network performance and user experience, all while maintaining cost and energy efficiency. The Fifth Generation (5G) cellular technology stands as the most significant advancement of this decade. Introduced as a revolutionary broadband technology, 5G addresses network requirements and enhances the quality of service for both mobile and residential users. Its introduction is accelerating global radio access network (RAN) densification, fostering new network designs, and enabling innovative applications with rigorous performance standards, such as reduced latency, higher throughput, and increased reliability. Consequently, 5G offers enhanced capacity and connectivity, supporting advanced applications and services that demand ultra-high connection speeds, traffic handling, and mobility. This technology will influence various aspects of daily life, including knowledge sharing, connectivity, entertainment, and safety. It supports a wide range of use cases, including smart city integration, autonomous vehicles, augmented reality, medical advancements, new forms of social interaction, and improved fixed wireless connectivity. Optical access networks have been providing both residential and mobile services for the final kilometers via various fiber topologies. However, deploying wireline broadband networks entails significant capital investment and a commitment to mid to long-term funding. The deployment of the last few hundred meters, known as the last mile, has been particularly challenging for wireline broadband technologies. A time-efficient and cost-effective alternative for last-mile deployment is Fixed Wireless Access (FWA). This innovative approach facilitates the quick and easy rollout of broadband networks. With the advent of 5G, FWA is set to become the fastest-growing residential broadband access technology. 5G FWA enables carriers to address the growing demand for high-speed broadband services more efficiently and with faster time-to-market solutions. This book, Fixed Wireless Access: Revolutionizing Connectivity in the Digital Age, aims to comprehensively explore FWA, tracing its historical development, examining its current applications, and assessing its future potential. The book begins with a thorough examination of the foundational principles of FWA, providing readers with an in-depth understanding of its components, technologies, and deployment strategies. It then delves into the technical intricacies, market dynamics, and real world applications that underscore the versatility and significance of FWA. In this context, it explores the transformative potential of 5G technology in delivering highspeed broadband services. So, several key areas, including high-frequency spectrum bands, advanced transmission schemes, multiconnectivity, adaptive numerology, and Integrated Access and Backhaul (IAB), among other things, which are critical for enhancing network performance, increasing capacity, and reducing latency, are covered. Beyond offering technical insights, the book highlights the socio-economic impact of FWA. By enabling cost-effective connectivity in remote and underserved areas, FWA has the potential to narrow or bridge the digital divide, fostering inclusivity and providing access to education, healthcare, and economic opportunities for all. This makes the book a crucial resource for grasping the future of broadband connectivity and the strategic approaches required to tackle deployment challenges. This book is intended to be a definitive guide for professionals, researchers, policymakers, and anyone interested in understanding the nuances and implications of this transformative technology.
