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."

With communications technologies rapidly expanding, the traditional separation of electronic circuits and antenna systems design is no longer feasible. This book covers various design approaches applicable to integrated circuit-antenna modules with the goal of placing the antenna, transmitter, and receiver all on a single chip. It emphasizes analysis and design involving the integration of circuit functions with radiating elements and addresses trends in systems miniaturization.

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.

Over the past two decades we have witnessed the increasing popularity of the internet of things. The vision of billions of connected objects, able to interact with their environment, is the key driver directing the development of future communication devices. Today, power consumption as well as the cost and size of radios remain some of the key obstacles towards fulfilling this vision. Ultra-Low Power FM-UWB Transceivers for IoT presents the latest developments in the field of low power wireless communication. It promotes the FM-UWB modulation scheme as a candidate for short range communication in different IoT scenarios. The FM-UWB has the potential to provide exactly what is missing today. This spread spectrum technique enables significant reduction in transceiver complexity, making it smaller, cheaper and more energy efficient than most alternative options. The book provides an overview of both circuit-level and architectural techniques used in low power radio design, with a comprehensive study of state-of-the-art examples. It summarizes key theoretical aspects of FM-UWB with a glimpse at potential future research directions. Finally, it gives an insight into a full FM-UWB transceiver design, from system level specifications down to transistor level design, demonstrating the modern power reduction circuit techniques. Ultra-Low Power FM-UWB Transceivers for IoT is a perfect text and reference for engineers working in RF IC design and wireless communication, as well as academic staff and graduate students engaged in low power communication systems research.
