Wireless communication has become a ubiquitous part of modern life, from global cellular telephone systems to local and even personal-area networks. This 2004 book provides a tutorial introduction to ...digital mobile wireless networks, illustrating theoretical underpinnings with a wide range of real-world examples. The book begins with a review of propagation phenomena, and goes on to examine channel allocation, modulation techniques, multiple access schemes, and coding techniques. GSM and IS-95 systems are reviewed and 2.5G and 3G packet-switched systems are discussed in detail. Performance analysis and accessing and scheduling techniques are covered, and the book closes with a chapter on wireless LANs and personal-area networks. Many worked examples and homework exercises are provided and a solutions manual is available for instructors. The book is an ideal text for electrical engineering and computer science students taking courses in wireless communications. It will also be an invaluable reference for practising engineers.

This book examines the influence of mobile media technology on the lives of young people in East and North Asia, South East Asia and Australia. It discusses the impact information communication ...technologies have today on social identity, well-being, participation and exclusion. It explores current media practices and their innovative, transformative and disruptive uses at the local, the regional, the national, and the global level. In particular, it analyses mobile media not as a discrete object, but rather as part of a dynamic communication and information environment in which human-object relations are constantly reconfigured. It covers key theoretical and conceptual themes in youth mobile media research focusing on social, cultural and political aspects, including coverage of key themes such as regulation and technology, practices, pedagogies, aesthetics, social change, and representations of mobile youth. The book includes new accounts of recent research into the uses of mobile media by young people, and how these are situated in a broader socio-political context. Case studies include mobile panics in Australia (the notorious Kings of Wirrabee sexual assault case) and Japan (the scandals of high school girls as teenage prostitutes) in which mobile media use has had significant impact. This book offers an up-to-date examination of the influence of information communication technologies on young people’s lives in the region.

New high-data-rate multimedia services and applications are evolving continuously and exponentially increasing the demand for wireless capacity of fifth-generation (5G) and beyond. The existing radio ...frequency (RF) communication spectrum is insufficient to meet the demands of future high-data-rate 5G services. Optical wireless communication (OWC), which uses an ultra-wide range of unregulated spectrum, has emerged as a promising solution to overcome the RF spectrum crisis. It has attracted growing research interest worldwide in the last decade for indoor and outdoor applications. OWC offloads huge data traffic applications from RF networks. A 100 Gb/s data rate has already been demonstrated through OWC. It offers services indoors as well as outdoors, and communication distances range from several nm to more than 10 000 km. This paper provides a technology overview and a review on optical wireless technologies, such as visible light communication, light fidelity, optical camera communication, free space optical communication, and light detection and ranging. We survey the key technologies for understanding OWC and present state-of-the-art criteria in aspects, such as classification, spectrum use, architecture, and applications. The key contribution of this paper is to clarify the differences among different promising optical wireless technologies and between these technologies and their corresponding similar existing RF technologies.
With the radical changes in information production that the Internet has introduced, we stand at an important moment of transition, says Yochai Benkler in this thought-provoking book. The phenomenon ...he describes as social production is reshaping markets, while at the same time offering new opportunities to enhance individual freedom, cultural diversity, political discourse, and justice. But these results are by no means inevitable: a systematic campaign to protect the entrenched industrial information economy of the last century threatens the promise of today's emerging networked information environment.
In this comprehensive social theory of the Internet and the networked information economy, Benkler describes how patterns of information, knowledge, and cultural production are changing-and shows that the way information and knowledge are made available can either limit or enlarge the ways people can create and express themselves. He describes the range of legal and policy choices that confront us and maintains that there is much to be gained-or lost-by the decisions we make today.
The Work of Communication: Relational Perspectives on Working and Organizing in Contemporary Capitalism revolves around a two-part question: "What have work and organization become under contemporary ...capitalism—and how should organization studies approach them?" Changes in the texture of capitalism, heralded by social and organizational theorists alike, increasingly focus attention on communication as both vital to the conduct of work and as imperative to organizational performance. Yet most accounts of communication in organization studies fail to understand an alternate sense of the "work of communication" in the constitution of organizations, work practices, and economies. This book responds to that lack by portraying communicative practices—as opposed to individuals, interests, technologies, structures, organizations, or institutions—as the focal units of analysis in studies of the social and organizational problems occasioned by contemporary capitalism. Rather than suggesting that there exists a canonically "correct" route communicative analyses must follow, The Work of Communication: Relational Perspectives on Working and Organizing in Contemporary Capitalism explores the value of transcending longstanding divides between symbolic and material factors in studies of working and organizing. The recognition of dramatic shifts in technological, economic, and political forces, along with deep interconnections among the myriad of factors shaping working and organizing, sows doubts about whether organization studies is up to the vital task of addressing the social problems capitalism now creates. Kuhn, Ashcraft, and Cooren argue that novel insights into those social problems are possible if we tell different stories about working and organizing. To aid authors of those stories, they develop a set of conceptual resources that they capture under the mantle of communicative relationality. These resources allow analysts to profit from burgeoning interest in notions such as sociomateriality, posthumanism, performativity, and affect. It goes on to illustrate the benefits that investigations of work and organization can realize from communicative relationality by presenting case studies that analyze (a) the becoming of an idea, from its inception to solidification, (b) the emergence of what is taken to be the "the product" in high-tech startup entrepreneurship, and (c) the branding of work (in this case, academic writing and commercial aviation) through affective economies. Taken together, the book portrays "the work of communication" as simultaneously about how work in the "new economy" revolves around communicative practice and about how communication serves as a mode of explanation with the potential to cultivate novel stories about working and organizing. Aimed at academics, researchers, and policy makers, this book’s goal is to make tangible the contributions of communication for thinking about contemporary social and organizational problems.
