"In the last few years we have heard fantastic things about 3 generation systems and the incredible services they will provide. Unfortunately most of these were just that: fantastic and incredible. On the other hand most of us missed the point of what the next generation mobile can enable and what real new services are becoming possible. This book is a must read if you want to understand options, future services and dream about them from a rock solid standpoint" Roberto Saracco, Director, Future Centre, Telecom Italia Lab .
