Produktbeschreibung

5G Non-Terrestrial Networks Provides a complete and detailed description of the non-terrestrial component in the 5G ecosystem 5G Non-Terrestrial Networks is the first multi-authored reference dedicated to the integration of non-terrestrial networks (NTN) into the 5G ecosystem. Written by leaders in the development of the 3GPP 5G NTN specification, this authoritative resource addresses all key aspects of non-terrestrial components of 5G systems, including standardization, architecture, protocols, and regulatory considerations. Drawing from their expertise in academic and industrial research and development, the authors introduce fundamental principles of non-terrestrial communications, define the NTN architecture and radio protocol stacks, describe applications to support mobility and radio resource management, and more. The book covers 5G New Radio-based technology for NTN as well as LTE NB-IoT/eMTC, providing a well-rounded understanding of the unique characteristics of 5G-NTN systems. Throughout the text, the authors offer insights on various design approaches, technical choices, and trade-off options. In addition, the book: * Addresses the integration of non-terrestrial networks into 5G systems at all levels * Describes the principles of non-terrestrial systems, including orbital parameters, link budget, propagation, and space/ground segments * Includes a detailed overview of 5G-NTN system architectures, deployment scenarios, and spectrum aspects * Covers NB-IoT and eMTC in NTN, NTN use cases, 5G QoS, and New Radio * Discusses the potential of non-terrestrial components of 5G in the future 6G ecosystem 5G Non-Terrestrial Networks is a must-have for communication engineers, satellite network operators, aerospace and electrical engineers, network engineers, academic researchers and industry professionals involved in 5G infrastructure development, as well as advanced students taking courses on 5G and satellite communication.
