Predictions suggest that the customer base will exceed 1 billion within the next ten years and that the saturation level is around 80% of any population. Faced with such statistics any book such as this can proffer little more than a snapshot of the activities and developments that are at present taking place within the mobile world. It can, however, reflect on some of the underlying principles that support the industry. The opening chapter offers a vision for the future of mobile communications - that of more mobile than fixed connections to the world‘s telecommunica tions networks - one which, interestingly, pre-dates the emergence of the information superhighway.
