Book Description
What started with the sundial has, thus far, been refined to a level of precision based on atomic resonance: Time. Our obsession with time is evident in this continued scaling down to nanosecond resolution and beyond. But this obsession is not without warrant. Precision and time synchronization are critical in many applications, such as air traffic

Book Description
This book presents the latest research results in the area of secure localization for both wireless mobile ad hoc networks and wireless sensor networks. It is suitable as a text for computer science courses in wireless systems and security. It includes implementation studies with mica2 mote sensors. Due to the open spectrum nature of wireless communication, it is subject to attacks and intrusions. Hence the wireless network synchronization needs to be both robust and secure. Furthermore, issues such as energy constraints and mobility make the localization process even more challenging. The book will also interest developers of secure wireless systems.

Book Description
Network synchronization deals with the distribution of time and frequency across a network of clocks often spread over a wide geographical area. The goal is to align (i.e. synchronize) the time and frequency scales of all clocks, by using the communication capacity of their interconnecting links. Network synchronization plays a central role in digital telecommunications as it determines the quality of most services offered by the network operator. However, the importance of network synchronization is often underestimated and how to solve quality-of-service degradation caused by synchronization difficulties can become problematical to all but a synchronization engineer. * Systematically covers a wide spectrum of both theoretical and practical topics * Features a clear and profound description of synchronous and asynchronous digital multiplexing (PDH, SDH), jitter and timing aspects of SDH networks * Expounds synchronization network principles and implementation issues, clock modelling, time and frequency measurement * Presents recent advances in telecommunications clock characterization and measurement If you are a system engineer, researcher, designer or postgraduate student searching for both the basics and an insight into more advanced areas currently under discussion then you will find Synchronization of Digital Telecommunications Networks an enlightening read. It will also prove to be a valuable sourcebook for senior undergraduates and technical personnel in telecommunications companies.

Book Description
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.

Book Description
The complete guide to timing and synchronization in advanced service provider networks and enterprise applications As networks have advanced, so has the need for precise timing and synchronization--including highly accurate phase synchronization. Without it, networks become increasingly vulnerable to outages, data loss events, and inefficiencies that can be notoriously difficult to diagnose. 5G telecom networks have especially stringent requirements, but they also apply to a growing number of enterprise applications in finance, factory automation, IoT, media, and beyond. Synchronizing 5G Mobile Networks is the definitive, comprehensive guide to all aspects of timing and synchronization. Drawing on extensive experience developing and implementing timing and synchronization systems, three leading experts cover standards, protocols, clock design, architecture, solution design, deployment tradeoffs, day-to-day operations, troubleshooting, and more. This book will be valuable to professionals with diverse backgrounds, even those with no timing or synchronization experience. It will be especially useful to engineers and consultants designing or implementing mobile networks; test engineers validating equipment or production solutions; students seeking careers with service providers or in advanced private networks; and technology leaders seeking to understand the growing role of time synchronization. Understand timing and synchronization concepts, goals, sources, and transport Explore timing applications in telecommunications and beyond Build synchronous networks with clocks, timing reference sources, time distribution, and timing signal consumption Review the role of standards development organizations in defining standards for timing and synchronization Drill down into the details of clocks, clock signals, and clock components Review traditional TDM-based techniques for frequency synchronization Explore precision time protocol (PTP) characteristics, features, profiles, and security Master best practices for designing and deploying timing in physical and packet-based networks Thoroughly understand timing metrics and end-to-end time error budgeting Establish accurate timing and synchronization in advanced 5G and LTE networks, including 5G New Radio and RAN environments Manage tradeoffs in synchronizing diverse cell sites, topologies, radio types, and mobile generations Verify, operate, monitor, and troubleshoot timing systems
