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. The book 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. High-frequency spectrum bands, such as those above 24 GHz, are essential for providing the necessary bandwidth to support high data rates and capacity. The book explains how these bands, while offering unprecedented peak rates, present challenges such as limited coverage and penetration, which are addressed through advanced technical solutions. Advanced transmission schemes, including massive beamforming and Multiple-Input Multiple-Output, are explored in detail. These technologies enable the efficient use of the spectrum by allowing multiple user terminals to be served simultaneously on the same frequency resources, thereby increasing the overall network capacity and improving user experiences. Multi-connectivity and adaptive numerology are also key topics. Multi-connectivity allows user equipment to connect to multiple network nodes simultaneously, improving reliability and performance.
