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.

R2,880 Discovery Miles 28 800 Ships in 10 - 15 working days

The area of analog integrated circuits is facing some serious challenges due to the ongoing trends towards low supply voltages, low power consumption and high-frequency operation. The situation is becoming even more complicated by the fact that many transfer functions have to be tunable or controllable. A promising approach to facing these challenges is given by the class of dynamic translinear circuits, which are, as a consequence, receiving increasing interest. Several different names are used in literature: log-domain, exponential state-space, current-mode companding, instantaneous companding, tanh-domain, sinh-domain, polynomial state-space, square-root domain and translinear filters. In fact, all these groups are (overlapping) subclasses of the overall class of dynamic translinear circuits. Research Perspectives on Dynamic Translinear and Log-Domain Circuits is a compilation of research findings in this growing field. It comprises ten contributions, coming from recognized `dynamic-translinear' researchers in Europe and North America. Research Perspectives on Dynamic Translinear and Log-Domain Circuits is an edited volume of original research.

Abid Yahya
R3,421 Discovery Miles 34 210 Ships in 12 - 19 working days

In this book, three different methods are presented to enhance the capacity and coverage area in LTE-A cellular networks. The scope involves the evaluation of the effect of the RN location in terms of capacity and the determination of the optimum location of the relay that provides maximum achievable data rate for users with limited interference at the cell boundaries. This book presents a new model to enhance both capacity and coverage area in LTE-A cellular network by determining the optimum location for the RN with limited interference. The new model is designed to enhance the capacity of the relay link by employing two antennas in RN. This design enables the relay link to absorb more users at cell edge regions. An algorithm called the Balance Power Algorithm (BPA) is developed to reduce MR power consumption. The book pertains to postgraduate students and researchers in wireless & mobile communications.

Transformation Optics-based Antennas is organized into two chapters that follow an introduction that presents the basic principles of the transformation optics concept. Two types of transformation are presented, coordinate transformation and space transformation. Implementations using metamaterials are also discussed. Chapter One focuses on coordinate transformation in the design of devices capable of modifying the electromagnetic appearance of a radiating source. Transformation of a directive radiation pattern into an isotropic one (and vice-versa) through space stretching and compression, respectively, and the possibility of creating multiple beams are also studied. Chapter Two deals with devices designed using space transformation concepts. Quasi-conformal transformation optics (QCTO) are applied for the design of lenses, either to compensate for the phase shift created by the conformation of an array of sources or to steer a beam to an off-normal direction.
