As we enter the next millenium, the technological revolution is all set to speed up. Advances will be shaped by many factors: technological breakthroughs; market forces; politics; and economics. Yet more importantly, they will be shaped by human and social factors, and the success or failure of products and services will largely be driven by consumer demand. This study of the future of telecommunications sets out to distinguish between what will become reality and what will remain hypothetical, focusing on the most feasible developments. It covers a wide range of telecommunication services, from components to networks, from mobile to wideband services, from telephones to interactive television.
