ABSTRACT

The mobile device originated as a cellular phone made to connect to a new cellular wireless network and through it to the existing copper wire voice network. As all the world knows, this portable device has evolved into a multimedia, multifunction digital platform now converging with the portable computer and television. Companies are innovating and jockeying to fi nd the business model to exploit the preferences of the public that uses cell phones and mobile media. By the time a fourth edition of this book might go to press, many uncertainties of the present moment will have become clear. But we can’t wait, because the rate of change in Internet and mobile media broadband is accelerating as we write.
