How wireless technology is redefining the relationship of communication, technology, and society around the world—in everyday work and life, in youth culture, in politics, and in the developing world. Wireless networks are the fastest growing communications technology in history. Are mobile phones expressions of identity, fashionable gadgets, tools for life—or all of the above? Mobile Communication and Society looks at how the possibility of multimodal communication from anywhere to anywhere at any time affects everyday life at home, at work, and at school, and raises broader concerns about politics and culture both global and local. Drawing on data gathered from around the world, the authors explore who has access to wireless technology, and why, and analyze the patterns of social differentiation seen in unequal access.They explore the social effects of wireless communication—what it means for family life, for example, when everyone is constantly in touch, or for the idea of an office when workers can work anywhere. Is the technological ability to multitask further compressing time in our already hurried existence? The authors consider the rise of a mobile youth culture based on peer-to-peer networks, with its own language of texting, and its own values. They examine the phenomenon of flash mobs, and the possible political implications. And they look at the relationship between communication and development and the possibility that developing countries could "leapfrog" directly to wireless and satellite technology. This sweeping book—moving easily in its analysis from the United States to China, from Europe to Latin America and Africa—answers the key questions about our transformation into a mobile network society.
In the few short decades since their commercial deployment, 5 billion people—about three-quarters of all humanity, including children—have become mobile phone users. No technology has even approached the mobile phone’s wildfire success. Effects of this success are apparent everywhere, ranging from accident scenes and earthquake rescue efforts to demeanor in the classroom and at dinner tables. No one interested in the next generation of issues provoked by the mobile communication revolution will want to miss this important new collection of essays. The mobile phone has given near-transcendent power to ordinary people. All aspects of social life have been touched by mobile technology. An ever-growing host of tracking, immersion, gaming, and commercial applications are becoming available. The community of mobile communication scholars has blossomed from a handful of pioneers a decade ago to a large and dynamic intellectual community that spans the globe. Area researchers have gained much insight into cultural, symbolic, and social interaction aspects of mobile communication as well as its relevance to commerce. To address the social policy dimension of the mobile communication revolution, this volume presents analyses by leading thinkers in the field. The volume offers novel and keen insights into the topic. Subjects include the role of mobiles in policy formation and evaluation in several areas including the mobile-digital divide and political campaigns. Also explored are processes and policy implications of mobiles in creating or alleviating social problems including social isolation and family dispersion. Other chapters analyze social policies for mobile devices, including attempts to regulate the use of the technology and to understand and moderate its potential harm to human health. The contributors’ scope ranges across five continents and they address concerns at local, national, and international levels.
A comprehensive discussion of multiple access protocols for cellular systems and the consideration of the specific constraints and capabilities of second and third generation systems regarding the multiple access protocols. Beginning by introducing the cellular concept and discussing second and third generation cellular communication systems, including the evolution from these systems to IP-based systems, the authors then identify the requirements for and problems related to multiple access. In accordance with ETSI and 3GPP standards, a split is made into basic multiple access schemes such as CDMA, TDMA and FDMA and multiple access protocols. The pros and cons of CDMA and TDMA for third generation systems are discussed as well as medium access in GSM, GPRS and UMTS, essentially based on R-ALOHA protocols in all these systems.

Mobile Communication covers a wide range of topics. These include the replacement of co-present interaction with mediated contact and analysis of mobile-based cohesion and gender. The authors also explore the role of media choice and its effect on the quality as well as quantity of social cohesion. Other topics include mobile communication and communities of interest; and mobile communication, cohesion, and youth. This volume brings together scholars from around the world to consider how mobile communication both builds and destroys our sense of social cohesion. There is no question that uses of technology can lead to increased cohesion within personal communities. For example, this volume includes research on caravan couples in Australia, factory workers in China, young couples in Germany, citizens in Slovenia, and sports clubs in Ireland. It also includes research on drunken calls between university students in the US, calls of international students in Switzerland and communications between immigrant women in Melbourne, Australia. However, the contributors also argue that as social networks become inundated with mobile communication users, these users may become increasingly isolated and social division can ensue.

This volume provides an original perspective on mobile communication, focusing on the emerging deployment of images in mobile phone usage: photography, video, mobile television, mobile internet, etc. Deeply embedded in our audiovisual culture, images possess the undeniable power to reshape the future of the mobile phone as an “individual mass medium”. In this collection, European researchers in media and communication studies, sociology, anthropology and political science present empirical and conceptual work on a wide range of issues, including cultural change, new forms of sociability on individual and societal levels, tactics and strategies of users and producers, and finally, representations and imaginaries of the mobile phone in other established media. This book is written for researchers and students of sociology, communication studies and cultural studies as well as for practitioners of interactive media and online communication.
This authoritative treatment of the fundamentals of mobile communications stresses the "fundamentals" of wireless and mobile communications engineering important for the design of "any" wireless system. The book differs from others in the field by stressing mathematical modelling and analysis.
This newly revised edition of an Artech House bestseller provides you with an up-to-date introduction to third generation (3G) mobile communication system principles, concepts, and applications.

It also features discussions on both 3GPP and 3GPP2 evolution paths, the specification process, and future 3G upgrades.
During the past decade there has been a dramatic change in the nature of mobile communications technology and its impact on the general communic ations environment. In the 1970s, mobile radio was a minority activity in communications, based on relatively unsophisticated technology. The 1980s, however, have seen the emergence of analogue cellular systems and the definition of future digital systems, and the predicted demand for these services is such that investigations into the use of higher frequency bands have already begun. It is predicted that, by the late 1990s, the 'personal communications' world will have resulted in the majority of adults in Europe and North America being dependent on radio-connected terminals of various kinds for more than 50% of their total telecommunications needs. The technology which will form the basis of this revolution has now been defined, at least in outline, and the fixed and mobile equipment that will be used in systems of the future will bear little resemblance to that available even ten years ago. It is impossible within the confines of a single, relatively short book to cover all the subject areas needed for a study of this exciting and expanding field of technology. We have, perforce, been selective and have chosen those topics which we believe to be of primary importance at the present time.
This edited volume is the first book-length study focusing entirely on mobile phone use in China. Drawing on examples from a wide range of contemporary situations in China and beyond, the contributors argue that the mobile phone is in fact an important means by which one can understand a rapidly changing China, and the developing culture of mobile phone usage reflects both the cultural norms and struggle of the people. Through a theoretical comparison of usage in the West and in China, the editors assert the uniqueness of China’s experience, highlighting that Chinese society is being exposed simultaneously to a rapid process of industrialization and cyberization. The contributors maintain that such density of experience under a compressed period combined with a thick cultural heritage and a country still under a dictating rule provides a unique situation and offers deep insights into Chinese culture in general. This work will be of great interest to all students and scholars of Asian communication studies, ICT and Chinese culture and society.
