In these crisscrossing threads are woven the fabric of a community, a society, an economy, a nation. And beyond that, the world itself. But the technology isn't the dream. The dream is what you can do with it.' Three revolutions changed the face of South Africa, the economic powerhouse of the African continent, in 1994. The first was democracy, as millions of newly-enfranchised citizens went to the polls to elect a new government. The second was the internet, bringing information, learning and entertainment into millions of homes. But the real signal of change in the air was the arrival of an electronic device that would put undreamed-of power into the hands of the people. The cellular phone. In a country where less than four per cent of the population had access to a landline phone, mobile telephony opened the gateway to new ways and new worlds of communication. Today, more than 90 per cent of South Africans own at least one mobile phone, and they're not just using them to talk to each other. Mobiles have become tools of education, entrepreneurship, trade, empowerment, activism, media and upliftment. With the advent of the mobile internet, mobiles have also become the hubs of the most powerful force in modern communication. The social network, bringing people together in an interchange of ideas, opinions, chatter and commerce that is changing the way we understand and define communities. This is the story of the biggest and fastest-growing social network in Africa. A network that took shape in the townships of the Western Cape and has grown to be part of the lives of more than 50 million users in 120 countries, sending more than 23 billion messages a month. This is the story of Mxit. A cultural force, a community of millions, with its own economy, its own infrastructure, its own language and its own traditions. This is the story of Mobinomics, the new economy of mobile, and how it is connecting people and changing lives. Read it and learn. Read it and understand. Read it and be moved by the power of mobile.

Today, millions people use mobile devices like smartphones and tablet computers on a daily basis to communicate and obtain information. Further, due to recent technical advances in mobile technology, consumers can use these devices to carry out a broad range of activities that previously required a desktop or laptop computer including shopping, banking, and accessing government services. Given these trends, providing government information and services "anytime, anywhere, and on any device" has become increasingly important, particularly as some mobile users may not have any other means of online access. This book describes the demographics of mobile users and the factors that might be associated with the increased use of mobile devices; the devices individuals are using to access government services and the challenges people face; and the actions the federal government has taken to enhance access to government services via mobile devices. This book also examines a report on Congress Member adoption and use of two social networking services: Twitter and Facebook. The book analyses data on Member use of Twitter and Facebook collected by an academic institution in collaboration with the Congressional Research Service during a two-month period between August and October 2011 and the adoption of both platforms as of January 2012.

Near field communication (NFC) can appear to be a simple intuitive technology for exchanging data between close devices. In reality, these contactless structures that combine components and antennas must respect important and specific working constraints. Illustrated by a number of detailed technological examples, this book discusses the multiple normative (ISO, CEN, NFC Forum, EMVCo, etc.) and regulatory (ERC, FCC, ETSI, radiofrequency, private and ecological pollution, etc.) constraints, as well as the applied, typological, functional, structural, environmental or interoperability constraints that a NFC device might face. Design Constraints for NFC Devices also presents techniques that enable us to free ourselves from the technological constraints of current NFC operations encountered in banking, public transport, administration, automotive, industrial, communicating object and Internet of Things applications.

Smartphone adoption has surpassed 50% of the population in more than 15 countries, and there are now more than one million mobile applications people can download to their phones. Many of these applications take advantage of smartphones as locative media, which is what allows smartphones to be located in physical space. Applications that take advantage of people s location are called location-based services, and they are the focus of this book. Smartphones as locative media raise important questions about how we understand the complicated relationship between the Internet and physical space. This book addresses these questions through an interdisciplinary theoretical framework and a detailed analysis of how various popular mobile applications including Google Maps, Facebook, Instagram, Yelp, and Foursquare use people s location to provide information about their surrounding space. The topics explored in this book are essential reading for anyone interested in how smartphones and location-based services have begun to impact the ways we navigate and engage with the physical world.

This innovative book sets forth two promising wireless approaches that support high-quality, high-speed data and multimedia service-multiple antenna technologies and cross layer transmitter adaptation designs-while highlighting the relationships and interactions between them. The latest advanced technologies of channel adaptation techniques for wireless communication systems with multiple antennas are thoroughly investigated.
The book is divided into three parts, first giving readers a good foundation in underlying theory, then exploring applications as well as advanced topics:
* Part 1 examines theoretical aspects of channel adaptation in wireless communications for point-to-point and multi-user systems with multiple antennas
* Part 2 focuses on the applications of the channel-adaptive technologies in practical systems such as UMTS
* Part 3 delves into topics such as multi-user scheduling for wideband systems, combined queuing theory and information theory, and ad hoc routing
Using a hands-on, practical approach, Channel Adaptive Technologies and Cross Layer Designs for Wireless Systems with Multiple Antennas thoroughly covers detailed design considerations that help readers understand how to apply theory to real-world systems. Emphasis throughout the book is on joint optimization across different layers of a communications system based on an integrated approach. Examples of popular wireless systems, such as TDMA, wideband CDMA (UMTS), and HSDPA, are used throughout as practical illustrations. Each chapter ends with a summary that reviews key points and a set of problems that lets readers test their knowledge and continue to develop their skills as they progress to new topics. Figures and tables are also used extensively to help readers visualize complex theory and systems.
Combining theory, design, and application into one integrated approach, this is a superior reference for advanced communications theory courses.
