Anyone wanting to set up a low cost web radio station will benefit from the advice and information provided by this book. Not only will you gain technical and practical know-how to enable your station to go live, but also an appreciation of the legal and copyright implications of making radio, potentially for international audiences and in the rapidly evolving environment of the web.
To succeed, your radio content will need to be carefully planned and your station properly promoted. Advice is given on taking advantage of the scalability web radio introduces for building audiences in line with your resources, for scheduled live output and for making programmes available on demand, including music, news, speech radio and audience participation. Case studies from around the world are provided to demonstrate how different radio organisations are applying the new flexibility web radio has to offer in a wide range of situations. Together with its associated website www.web-radio-book.com, the book also acts as a starting point for locating a range of sources for further advice and lines of research. Learn how to: - go live with your own low cost web radio station (either managing the server yourself or using a host service) - assess the right server set-up to handle the number of simultaneous listeners expected - get the best sound quality to your listeners - take account of the range of devices available for receiving web radio - plan your station, programming and associated website - identify and reach your audience - build audience feedback and data into your station's strategy - tackle the additional legal and ethical dimensions of radio on the web - source more detailed information

Описание: Television existed for a long time before it became commonplace in American homes. Even as cars, jazz, film, and radio heralded the modern age, television haunted the modern imagination. During the 1920s and 1930s, U.S. television was a topic of conversation and speculation. Was it technically feasible? Could it be commercially viable? What would it look like? How might it serve the public interest? And what was its place in the modern future? These questions were not just asked by the American public, but also posed by the people intimately involved in television’s creation. Their answers may have been self-serving, but they were also statements of aspiration. Idealistic imaginations of the medium and its impact on social relations became a de facto plan for moving beyond film and radio into a new era. In Television in the Age of Radio, Philip W. Sewell offers a unique account of how television came to be—not just from technical innovations or institutional struggles, but from cultural concerns that were central to the rise of industrial modernity. This book provides sustained investigations of the values of early television amateurs and enthusiasts, the fervors and worries about competing technologies, and the ambitions for programming that together helped mold the medium. Sewell presents a major revision of the history of television, telling us about the nature of new media and how hopes for the future pull together diverse perspectives that shape technologies, industries, and audiences.

Описание: Published in 2012 only in France, this English translation is the first book to discuss the specific antennas used in cellular and Private Mobile Radio (PMR) networks. These are the antennas located on pylons in rural areas and tubular masts on rooftops in more populated areas. The book presents essential information for engineers, managers, and technicians working for mobile phone equipment manufacturers, network integrators, and antenna installation companies.The book is divided into three sections: the first section describes the functioning of all types of antennas used in mobile phone networks and provides examples of each; the second part delves into the engineering of antenna sites, which is crucial to the quality of mobile networks; the third part of the book includes refresher information on the mathematics and physics necessary to understand the content of the book and put it to practical use in actual applications. Packed with clear explanations and recommendations for avoiding problems and making the best antenna and site decisions.

Описание: With the increasing market penetration of cellular telephones, the number of E-911 calls placed by cellular telephones has grown cons- erably. Phase II, to be completed by October 1, 2001, is much more stringent and requires that the location of an E-911 caller be determined and reported with an rms location accuracy of 125 m in 67% of the cases.

Описание: This brief examines current research on cooperative device-to-device (D2D) communication as an enhanced offloading technology to improve the performance of cognitive radio cellular networks.
This book deals with the field of identification and sensors, more precisely the possibility of collecting information remotely with RF waves (RFID). The book introduces the technology of chipless RFID starting from classical RFID and barcode, and explores the field of identification and sensors without wire, without batteries, without chip, and with tags that can even be printed on paper.
A technique for automatic design of UHF RFID tags is presented, aiming at making the tags as insensitive as possible to the environment (with the ability to increase the reading range reliability), or, conversely, making them sensitive in order to produce sensors, meanwhile keeping their unique ID. The RFID advantages are discussed, along with its numerous features, and comparisons with the barcode technology are presented. After that, the new chipless RFID technology is introduced on the basis of the previous conclusions. Original technological approaches are introduced and discussed in order to demonstrate the practical and economic potential of the chipless technology.

With nearly 7 billion mobile phone subscriptions worldwide, mobility and computing have become pervasive in our society and business. Moreover, new mobile multimedia communication services are challenging telecommunication operators. To support the significant increase in multimedia traffic--especially video--over wireless networks, new technological infrastructure must be created. Cognitive Radio Networks (CRNs) are widely regarded as one of the most promising technologies for future wireless communications. This book explains how to efficiently deliver video, audio, and other data over CRNs.
Covering advanced algorithms, protocols, and hardware-/software-based experiments, this book describes how to encode video in a prioritized way to send to dynamic radio links. It discusses different FEC codes for video reliability and explains how different machine learning algorithms can be used for video quality control. It also explains how to use readily available software tools to build a CRN simulation model.
This book explains both theoretical and experimental designs. It describes how universal software radio peripheral (USRP) boards can be used for real-time, high-resolution video transmission. It also discusses how a USRP board can sense the spectrum dynamics and how it can be controlled by GNU Radio software. A separate chapter discusses how the network simulator ns-2 can be used to build a simulated CRN platform.
