Nextgen Network Synchronization

This book presents time synchronization and its essential role as a conduit of optimized networks and as one of the key imperatives of ubiquitous connectivity. The author discusses how, without proper time synchronization, many mission critical infrastructures such as 5G mobile networks, smart grids, data centres CATV, and industrial networks would render in serious performance issues and may be subject to catastrophic failure. The book provides a thorough understanding of time synchronization from fundamental concepts to the application of time synchronization in NextGen mission critical infrastructure. Readers will find information not only on designing the optimized products for mission critical infrastructure but also on building NextGen mission critical infrastructure. Presents time synchronization and its importance in modern smart network infrastructure; Addresses sync plane issues of 5G mobile network infrastructure and designing optimized edge cloud and telecom cloud infrastructure; Discusses building optimized transport systems for smart grid, data centres CATV, and industrial network infrastructure.

This book addresses the multiple technical aspects of the distribution of synchronization in new generation telecommunication networks, focusing in particular on synchronous Ethernet and IEEE1588 technologies. Many packet network engineers struggle with understanding the challenges that precise synchronization distribution can impose on networks. The usual “why”, “when” and particularly “how” can cause problems for many engineers. In parallel to this, some other markets have identical synchronization requirements, but with their own design requirements, generating further questions. This book attempts to respond to the different questions by providing background technical information. Invaluable information on state of-the-art packet network synchronization and timing architectures is provided, as well as an unbiased view on the synchronization technologies that have been internationally standardized over recent years, with the aim of providing the average reader (who is not skilled in the art) with a better understanding of this topic. The book focuses specifically on synchronous Ethernet and IEEE 1588 PTP-based technologies, both key developments in the world of synchronization over the last 10 years. The authors address the needs of engineers and technical managers who are struggling with the subject of synchronization and provide an engineering reference for those that need to consider synchronization in NGN. The market applications that are driving the development of packet network synchronization and timing architectures are also discussed. This book provides a wide audience with everything they need to know when researching, implementing, buying and deploying packet synchronization architectures in telecommunication networks.

There is a need to be aware of the challenges awaiting us in next generation (NextGen) networks in order to take the proper steps to either minimize or eliminate issues as they present themselves. Incorporating artificial intelligence in NextGen networks for privacy and security policies will serve this purpose. It is essential to stay current with these emerging technologies and applications in order to maintain safe and secure communications in the future. Challenges and Risks Involved in Deploying 6G and NextGen Networks explores strategies for the design and deployment of more secured and user-centered NextGen networks through artificial intelligence to enrich user experience. It further investigates the political, social, and geographical challenges involved in realizing these 6G networks and explores ways to improve the security of future potential applications as well as protect user data from illegal access. Covering topics such as deep learning algorithms, aerial network communication, and edge computing, this major reference work is an indispensable resource for regulatory and policy groups, associations and technology groups, government and international bodies, technology executives and technical institutions, management consulting and advisory firms, communication engineers, network engineers, students and educators of higher education, researchers, and academicians.

Advanced Sensor Technology: Biomedical, Environmental, and Construction Applications introduces readers to the past, present and future of sensor technology and its emerging applications in a wide variety of different fields. Organized in five parts, the book covers historical context and future outlook of sensor technology development and emerging applications, the use of sensors throughout many applications in healthcare, health and life science research, public health and safety, discusses chemical sensors used in environmental monitoring and remediation of contaminants, highlights the use of sensors in food, agriculture, fire prevention, automotive and robotics, and more. Final sections look forward at the challenges that must be overcome in the development and use of sensing technology as well as their commercial use, making this book appropriate for the interdisciplinary community of researchers and practitioners interested in the development of sensor technologies. Covers a range of environmental applications such as protection and improvement of water, air, soil, plants, and agriculture and food production; biomedical applications including detection of viruses, genes, hormones, proteins, bacteria, and cancer, and applications in construction such as fire protection, automotive, robotics, food packing and micro-machining Provides an outlook on opportunities and challenges for the fabrication and manufacturing of sensors in industry and their applicability for industrial uses Demonstrates how cutting-edge developments in sensing technology translate into real-world innovations in a range of industry sectors
