Book Description
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.

Book Description
This book describes the technologies involved in all aspects of a large networking system and how the various devices can interact and communicate with each other. Using a bottom up approach the authors demonstrate how it is feasible, for instance, for a cellular device user to communicate, via the all-purpose TCP/IP protocols, with a wireless notebook computer user, traversing all the way through a base station in a cellular wireless network (e.g., GSM, CDMA), a public switched network (PSTN), the Internet, an intranet, a local area network (LAN), and a wireless LAN access point. The information bits, in travelling through this long path, are processed by numerous disparate communication technologies. The authors also describe the technologies involved in infrastructure less wireless networks.

Book Description
The mobile industry for wireless cellular services has grown at a rapid pace over the past decade. Similarly, Internet service technology has also made dramatic growth through the World Wide Web with a wire line infrastructure. Realization for complete wired/wireless mobile Internet technologies will become the future objectives for convergence of these technologies through multiple enhancements of both cellular mobile systems and Internet interoperability. Flawless integration between these two wired/wireless networks will enable subscribers to not only roam worldwide, but also to solve the ever increasing demand for data/Internet services. In order to keep up with this noteworthy growth in the demand for wireless broadband, new technologies and structural architectures are needed to greatly improve system performance and network scalability while significantly reducing the cost of equipment and deployment. Dr. Rhee covers the technological development of wired/wireless internet communications in compliance with each iterative generation up to 4G systems, with emphasis on wireless security aspects. By progressing in a systematic matter, presenting the theory and practice of wired/wireless mobile technologies along with various security problems, readers will gain an intimate sense of how mobile internet systems operate and how to address complex security issues. Features: Written by a top expert in information security Gives a clear understanding of wired/wireless mobile internet technologies Presents complete coverage of various cryptographic protocols and specifications needed for 3GPP: AES, KASUMI, Public-key and Elliptic curve cryptography Forecast new features and promising 4G packet-switched wireless internet technologies for voice and data communications Provides MIMO/OFDMA-based for 4G systems such as Long Term Evolution (LTE), Ultra Mobile Broadband (UMB), Mobile WiMax or Wireless Broadband (WiBro) Deals with Intrusion Detection System against worm/virus cyber attacks The book ideal for advanced undergraduate and postgraduate students enrolled in courses such as Wireless Access Networking, Mobile Internet Radio Communications. Practicing engineers in industry and research scientists can use the book as a reference to get reacquainted with mobile radio fundamentals or to gain deeper understanding of complex security issues.
