This welcome new edition of 5G Technology is now expanded and updated to provide an insiders-view of the development work of 5G technology up to Release 17, planned for summer 2022. 5G brings new technology solutions to the 5G mobile networks including new spectrum options, new antenna structures, new physical layer and protocols designs and new network architectures. This book is an accessible, comprehensive resource that offers explanations of 5G specifications, performance evaluations, aspects of device design, practical deployment considerations and illustrative examples from field experiences. With contributions from a panel of international experts on the topic - industry insiders working at the forefront of development - the book presents the main new technology components in 5G and describes the physical layer, radio protocols and network performance. The authors review the deployment aspects such as site density and transport network and explore the 5G performance aspects including data rates and coverage and latency. Brand new chapters on O-RAN and Industrial IoT, amongst others, ensure that this book cements its reputation as the essential 5G reference for the tech community and students taking communications technology courses.

Die wichtigsten rundfunkpolitischen Problemstellungen bestimmen sich im Spannungsfeld zwischen Parteipolitisierung und Tendenzen zur Kommerzialisierung dieses Massenkommunikationsmittels. Der Rund funk ist nicht nur - mit den Worten des Bundesverfassungsgericht- ein Medium, sondern auch ein Faktor der offentlichen Meinungs bildung. Deshalb kann es nicht darum gehen, die Parteien aus den Kontrollgremien des Rundfunks herauszuhalten; denn die Parteien haben den grundgesetzlichen Auftrag, an der politischen Willensbil dung des Volkes mitzuwirken. Aber die Parteien sind nicht die ein zigen "gesellschaftlich relevanten Krafte," die mit ihren Ansichten und Interessen im Rundfunkprogramm reprasentiert sein wollen und dadurch die offentliche Meinungsbildung rundfunkpublizistisch zu beeinflussen suchen. Den zunehmenden Privatisierungsbestrebungen und den Kommerzialisierungstendenzen wird der offentlich-recht liche Rundfunk in der Bundesrepublik - zugunsten der publizisti schen Meinungsvielfalt - nur standhalten konnen, wenn die Pro grammverantwortlichen und -mitarbeiter nicht dem allfalligen Druck politischer Interessengruppen nachgeben; verpflichtend ist fur sie nicht dieser oder jener Parteistandpunkt oder sonstige Interessen standpunkt einer bestimmten gesellschaftlich relevanten Gruppe, sondern allein der demokratisch-pluralistische Programm auf trag. In diesem Sinne ist die folgende Aussage von Reinhard Appel uber zeugend und auch uber die angesprochenen politischen Parteien hinaus von allgemeiner Gultigkeit: "Gewiss vertreten die Parteien einen gros sen Teil der Interessen ihrer Wahler. Aber sie reprasentieren doch nicht automatisch das Gemeinwohl. Sie verfolgen haufig, auch durch den Machtkampf bedingt, Interessen, die nicht unbedingt mit denen ihrer Wahler identisch sind. Manches Wahlkampf thema wurde nur deshalb aufgegriffen, weil man meinte, damit besonders wirksam Wahlerstimmen gewinnen zu konnen."

Location-aware computing is a technology that uses the location (provides granular geographical information) of people and objects to derive contextual information. Today, one can obtain this location information free of cost through smartphones. Smartphones with location enabled applications have revolutionized the ways in which people perform their activities and get benefits from the automated services. It especially helps to get details of services in less time; wherever the user may be and whenever they want. The need for smartphones and location enabled applications has been growing year after year. Nowadays no one can leave without their phone; the phone seemingly becomes one of the parts of the human body. The individual can now be predicted by their phone and the identity of the phone becomes the person's identity. Though there is a tremendous need for location-enabled applications with smartphones, the debate on privacy and security related to location data has also been growing. Privacy and Security Challenges in Location Aware Computing provides the latest research on privacy enhanced location-based applications development and exposes the necessity of location privacy preservation, as well as issues and challenges related to protecting the location data. It also suggests solutions for enhancing the protection of location privacy and therefore users' privacy as well. The chapters highlight important topic areas such as video surveillance in human tracking/detection, geographical information system design, cyberspace attacks and warfare, and location aware security systems. The culmination of these topics creates a book that is ideal for security analysts, mobile application developers, practitioners, academicians, students, and researchers.

The aim of this book is to present the modern design and analysis principles of millimeter-wave communication system for wireless devices and to give postgraduates and system professionals the design insights and challenges when integrating millimeter wave personal communication system. Millimeter wave communication system are going to play key roles in modern gigabit wireless communication area as millimeter-wave industrial standards from IEEE, European Computer Manufacturing Association (ECMA) and Wireless High Definition (Wireless HD) Group, are on their way to the market. The book will review up-to-date research results and utilize numerous design and analysis for the whole system covering from Millimeter wave frontend to digital signal processing in order to address major topics in a high speed wireless system.

This book emphasizes the importance and the requirements of high-gain antennas, low power transceiver, adaptive equalizer/modulation, channeling coding and adaptive multi-user detection for gigabit wireless communications. In addition, the book will include the updated research literature and patents in the topics of transceivers, antennas, MIMO, channel capacity, coding, equalizer, Modem and multi-user detection. Finally the application of these antennas will be discussed in light of different forthcoming wireless standards at V-band and E-band.

Modern systems and means of aeronautical radio communication are continuously being improved, but without the development of new technical means, the aviation industry suffers. The development of more innovative plans of aviation technology are needed in order to respond to the ever-increasing standard of aviation technology. Recent Advances in Satellite Aeronautical Communications Modeling is devoted to the modeling of satellite communication channels for aircraft and RPAS/UAV using the Matlab Simulink and NetCracker software. Featuring research on topics such as channel coding, microwave emitters, and array modeling, this book is ideally designed for scientists, engineers, air traffic controllers, managers, researchers, and academicians.
