Village Phone replication manual : Creating Sustainable Access to Affordable Telecommunications for the Rural Poor

Few things are as central to life today, as the ability to make a phone call. It is something most of us take completely for granted—but something that millions of poor people in the villages of the developing world can rarely do. With no access to fixed-line telecommunications infrastructure, they cannot call a doctor when a child is sick, determine fair market prices for their crops, or easily contact family members in their capital city. The resulting isolation from today’s information-driven economy is a major factor contributing to their poverty and marginalization. The advent of affordable mobile communications has begun to change all this. In several low-income countries there are now more cell phones in use than installed lines. In the case of Grameen Village Phone, we see how the forces of innovation and the marketplace can widen the impact on this trend even further, improving living standards for large numbers of people by integrating entrepreneurship, microfinance, and mobile communications.

Commanding Communications. Navigating Emerging Trends in Telecommunications

A guide to the winning strategies of the most successful telecom firms and how to capitalize from themWith the dramatic increase in media deals, Web businesses, research, and investment, telecommunications has grown into an $850 billion industry. Drawing from his former position as director of KPMG's lucrative telecommunications practice, the author reveals the best strategies of today's top telecom firms. Readers will discover the steps they'll need to take in order to implement these strategies in their own businesses and capitalize on telecom's most advanced technologies.Joseph Bonocore (Corte Madera, CA) is the founder and CEO of Eclipse Networks. Prior to founding Eclipse, he was senior partner at KPMG where he held several positions including national director for the Telecommunications Industry, co-managing partner for KPMG's Information, Communication & Entertainment (ICE) Consulting Practice. He is a frequent speaker at industry events and is considered a highly regarded expert and strategist in the area of telecommunications.

Rethinking Rights and Regulations. Institutional Responses to New Communications Technologies

There is strong tendency, especially in the popular press, to think and write of new technologies as exogenous forces shaping society. The real-ity is that the interplay between society and technology is a complex improvisational dance in which each partner responds dynamically to the moves (or anticipated moves) of the other. New technologies are introduced in response to opportunities perceived in preexisting social, economic, and technological relationships. But these opportunities may be enhanced or diminished as affected interests respond; and the per-ceived opportunities themselves reflect institutional embodiments of soci-etal attitudes toward technology. Because technologies are embedded in social systems and are understood in this context,1 responses to new technologies may be as varied and complex as the social systems that incorporate (or reject) them. And just as social systems develop over long periods of time, so may societal responses to technologies evolve in stages over time as the long-term implications of new technologies become more evident, and as the social context of technology changes with society itself.

Modeling and Simulation Environment for Satellite and Terrestrial Communications Networks

Modeling and Simulation Environment for Satellite and Terrestrial Communications Networks: Proceedings of the European COSTTelecommunications Symposium will be of interest to network designers, developers, and operators. This book is a collection of papers given at the European Cost Telecommunications Symposium. The Symposium was broken down into four sessions: Modelling and Simulation. Teletraffic Modelling. Communications Networks Simulation. Problems in Simulation. Each session addressed a wide spectrum of subjects. The symposium covered nearly all of the important aspects of simulation modeling and tools for the design and performance evaluation of communication techniques and systems. Emerging techniques were emphasized.

Charging for Mobile All-IP Telecommunications

This book provides a complete and comprehensive overview of 3G UMTS charging servicesEvolving from offline billing of traditional telecommunications, charging for IP services in mobile networks is challenging; charging convergence is one of the major trends in the telecom industry. Advanced mobile telecommunications incorporates data applications with real-time control and management, and requires a convergent and flexible online charging system. Such convergence is essential to mitigate fraud and credit risks in order to provide more personalized information to users about charges and credit limit controls.Charging for Mobile All-IP Telecommunications provides comprehensive and practical coverage of online and offline charging based on mobile operator experiences, and the latest efforts undertaken by the UMTS specifications.

Digital Clocks for Synchronization and Communications

This handbook seeks to provide an in-depth and practical understanding of the digital clock technologies used in building today's telecommunications networks. Covering critical details on the PLL (phase-locked loop) technique for clock synchronization and generation, and the DDS (direct digital synthesizer) technique for clock generation, the work is designed to help the reader achieve synchronization in high-speed networks and frequency stabilization in portable equipment. Discussing both wired and wireless networks, the volume looks at the combination of circuits and systems to give you a more thorough understanding of important design requirements.
