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.
商品描述(中文翻譯)
本書探討了5G技術在透過無線方式提供高速寬頻服務的轉型潛力,特別針對服務不足的地區和農村地區。內容涵蓋幾個關鍵主題,包括高頻譜頻段、先進的傳輸方案、多連接性、自適應數字化以及整合接入與回傳(Integrated Access and Backhaul, IAB)。這些元素對於提升網絡性能、增加容量和降低延遲至關重要。
各章節探討了與24 GHz以上的高頻譜頻段相關的挑戰,以及先進技術解決方案如何應對這些問題。詳細探討了大規模波束成形(massive beamforming)和多輸入多輸出(Multiple-Input Multiple-Output, MIMO)技術的效率,以展示它們如何使多個用戶終端能夠在相同的頻率資源上同時服務。多連接性允許用戶設備同時連接到多個網絡節點,從而提高可靠性和性能。自適應數字化支持靈活的子載波間距,以滿足不同服務的質量要求。IAB利用相同的頻譜進行接入和回傳,簡化了部署並通過消除大量光纖安裝來降低成本。
除了這些技術見解外,本書還針對縮小數位鴻溝的更廣泛問題進行探討,旨在使高速互聯網在偏遠地區更具可及性。隨著全球對可靠互聯網接入需求的增長,這些解決方案的相關性愈加凸顯。通過利用5G FWA技術,本書旨在解決數位不平等的問題。
本書適合電信工程專業人士、專注於寬頻技術的研究人員、參與數位基礎設施規劃的政策制定者,以及任何對理解5G FWA對未來連接影響感興趣的人士。它作為克服部署挑戰的權威指南,確保互聯網技術的進步能惠及更廣泛的受眾。
