Abstract

The mobile phone has evolved from a basic device that just makes calls to a multifunctional gadget like the iPhone, which can also retrieve e-mail, store and play music, surf the Web, and stream video files. This reflects the advance in mobile technology from the 1980s´ first-generation (1G) circuit-switched analog systems to today´s 3G and even 3.5G digital technologies. The International Telecommunication Union is working on a 4G cellular standard, which the ITU plans to release in a couple of years. The technology would enable IP-based voice, data, and streaming multimedia at higher speeds-theoretically up to 288 megabits per second for mobile users-than current cellular approaches.
