 it will be their first camera, their first music player and, of course, their first Internet access. Mobile Revolution is a big word, you might say. Why not be more humble and call it a Mobile Evolution? Actually, the growth pattern of the cellular industry in the 1990s was very much evolutionary. However, in the last couple of years the momentum has attained a different quality. From making voice mobile we are moving to all aspects of our lives. Mobile music, mobile TV, mobile email and mobile office all allow us to liberate ourselves from a fixed location. People no longer need to rush back home in order not to miss the first minutes of a sports event on television and sales people update their sales catalogue and price lists over-the-air directly into the mobile device on the way to their clients. Mobile services with video capabilities have the capacity to transform the way production plants are being monitored and maintained. Complete value chains are just now being redefined. Sociologists have started academic studies on the effect of mobile communications on societies, for instance regarding community building among teenagers. Whereas tribal behaviour among teenagers used to be tied to a certain location, e.g. the local park, communities nowadays are formed through communications devices irrespective of location. This will have a significant effect on the way societies will develop. In April 1991, I saw the first commercial GSM Base Station in the field. Most probably the last pieces of this first generation equipment have long found their way into the technical museums of this world. Since then thousands of innovative and experienced engineers have worked together in order to take technology from GSM to GPRS, EDGE, WCDMA and HSPA; soft switching is replacing traditional switching concepts and IP technology enables true technology and service convergence. The true challenge of the future, however, does not lie in bringing even higher speeds into the networks or in connecting even more people faster. In my
