The purpose of this book is to explore a range of ideas that have the potential to lead to future paradigm shifts. We know the technology is evolving at a rapid rate, but it is almost impossible to predict the exact direction from which the next paradigm will emerge. This book represents 18 ideas that could result in paradigm shifts. The only criterion for inclusion in this book is that the idea has to represent a significant departure from the norm in exploring a new technology or application. The next generation of paradigm shifts in communication technology is going to start as "blue sky" ideas, evolving dreams into reality.
