An expert considers the effects of a more mobile Internet on socioeconomic development and digital inclusion, examining both potentialities and constraints. Almost anyone with a $40 mobile phone and a nearby cell tower can get online with an ease unimaginable just twenty years ago. An optimistic narrative has proclaimed the mobile phone as the device that will finally close the digital divide. Yet access and effective use are not the same thing, and the digital world does not run on mobile handsets alone. In After Access, Jonathan Donner examines the implications of the shift to a more mobile, more available Internet for the global South, particularly as it relates to efforts to promote socioeconomic development and broad-based inclusion in the global information society. Drawing on his own research in South Africa and India, as well as the burgeoning literature from the ICT4D (Internet and Communication Technologies for Development) and mobile communication communities, Donner introduces the “After Access Lens,” a conceptual framework for understanding effective use of the Internet by those whose “digital repertoires” contain exclusively mobile devices. Donner argues that both the potentialities and constraints of the shift to a more mobile Internet are important considerations for scholars and practitioners interested in Internet use in the global South.

A study of Internet blocking and filtering around the world: analyses by leading researchers and survey results that document filtering practices in dozens of countries. Many countries around the world block or filter Internet content, denying access to information that they deem too sensitive for ordinary citizens—most often about politics, but sometimes relating to sexuality, culture, or religion. Access Denied documents and analyzes Internet filtering practices in more than three dozen countries, offering the first rigorously conducted study of an accelerating trend. Internet filtering takes place in more than three dozen states worldwide, including many countries in Asia, the Middle East, and North Africa. Related Internet content-control mechanisms are also in place in Canada, the United States and a cluster of countries in Europe. Drawing on a just-completed survey of global Internet filtering undertaken by the OpenNet Initiative (a collaboration of the Berkman Center for Internet and Society at Harvard Law School, the Citizen Lab at the University of Toronto, the Oxford Internet Institute at Oxford University, and the University of Cambridge) and relying on work by regional experts and an extensive network of researchers, Access Denied examines the political, legal, social, and cultural contexts of Internet filtering in these states from a variety of perspectives. Chapters discuss the mechanisms and politics of Internet filtering, the strengths and limitations of the technology that powers it, the relevance of international law, ethical considerations for corporations that supply states with the tools for blocking and filtering, and the implications of Internet filtering for activist communities that increasingly rely on Internet technologies for communicating their missions. Reports on Internet content regulation in forty different countries follow, with each two-page country profile outlining the types of content blocked by category and documenting key findings.

Here's an authoritative, cutting-edge resource that gives you a thorough understanding of CDMA transmission and detection. It offers practical guidance in designing interference-reducing multi-user receivers for mobile radio systems and multi-user adaptive modems for accessing satellite earth stations. The book provides in-depth descriptions of CDMA principles, and of linear and non-linear multi-user detection, and covers the fine details of the realization of a linear multi-user receiver. Extensively supported with over 565 equations and more than 95 illustrations, the book enables you to devise accurate system models of both a cellular TD-CDMA radio interface and an asynchronous satellite radio interface. It allows you to choose among different architectural solutions for both linear multi-user receivers to be operated in TD-CDMA radio systems and adaptive linear CDMA receivers in satellite asynchronous CDMA systems.

Broadband Satellite Communications for Internet Access is a systems engineering methodology for satellite communication networks. It discusses the implementation of Internet applications that involve network design issues usually addressed in standard organizations. Various protocols for IP- and ATM-based networks are examined and a comparative performance evaluation of different alternatives is described. This methodology can be applied to similar evaluations over any other transport medium.

A study of the impact of Internet use on American society, based on a series of nationally representative surveys conducted from 1995 to 2000. Drawing on nationally representative telephone surveys conducted from 1995 to 2000, James Katz and Ronald Rice offer a rich and nuanced picture of Internet use in America. Using quantitative data, as well as case studies of Web sites, they explore the impact of the Internet on society from three perspectives: access to Internet technology (the digital divide), involvement with groups and communities through the Internet (social capital), and use of the Internet for social interaction and expression (identity). To provide a more comprehensive account of Internet use, the authors draw comparisons across media and include Internet nonusers and former users in their research. The authors call their research the Syntopia Project to convey the Internet's role as one among a host of communication technologies as well as the synergy between people's online activities and their real-world lives. Their major finding is that Americans use the Internet as an extension and enhancement of their daily routines. Contrary to media sensationalism, the Internet is neither a utopia, liberating people to form a global egalitarian community, nor a dystopia-producing armies of disembodied, lonely individuals. Like any form of communication, it is as helpful or harmful as those who use it.

High-speed Internet access: the definitive "how-to" guide! Covers cable, DSL, and next-generation wireless high-speed Internet connections, this handbook also Includes Windows, MacOS and Linux coverage.

A digital anthropologist examines the online lives of millions of people in China, India, Brazil, and across the Middle East—home to most of the world’s internet users—and discovers that what they are doing is not what we imagine. New-media pundits obsess over online privacy and security, cyberbullying, and revenge porn, but do these things really matter in most of the world? The Next Billion Users reveals that many assumptions about internet use in developing countries are wrong. After immersing herself in factory towns, slums, townships, and favelas, Payal Arora assesses real patterns of internet usage in India, China, South Africa, Brazil, and the Middle East. She finds Himalayan teens growing closer by sharing a single computer with common passwords and profiles. In China’s gaming factories, the line between work and leisure disappears. In Riyadh, a group of young women organizes a YouTube fashion show. Why do citizens of states with strict surveillance policies appear to care so little about their digital privacy? Why do Brazilians eschew geo-tagging on social media? What drives young Indians to friend “foreign” strangers on Facebook and give “missed calls” to people? The Next Billion Users answers these questions and many more. Through extensive fieldwork, Arora demonstrates that the global poor are far from virtuous utilitarians who mainly go online to study, find jobs, and obtain health information. She reveals habits of use bound to intrigue everyone from casual internet users to developers of global digital platforms to organizations seeking to reach the next billion internet users.
