Technological advances in many areas can build devices that were not possible 20, 10 or even 5 years too. Been the rapid development of integrated circuits (IC) is a major factor and other important factors are the rapid development of the color screen and camera. Advances in IC led to the reduction of the size and weight of mobile devices as required could be faster with smaller equipment and lower costs. Color high resolution screens allow complex applications and services are presented visually to 10 years ago were in the films were science fiction. The pace will occur in which these technological advances is staggering and difficult to predict.
The Apple iPhone is an excellent example of a telephone, small, smooth and has some amazing applications that 5 years ago would have been difficult to sustain such a device. Apple have traditional mobile manufacturers like Nokia and Ericsson, the demand to provide equipment services to customers based show is much better than a high specification supports the latest mobile 3GPP specifications. The iPhone is an instrument of weakness in relation to RF functions, but the average citizen really does not matter if the phone works.
