Adding New Functionality to Wireless Handsets

摘要

While The 3G wireless revolution has captured the attention of the industry and the general public, a quieter evolution in the functionality of 2.5G wireless handsets is also taking place. Increasingly, handsets are integrating multiple applications, such as digital still image capture, and sophisticated ring tones using methods such as MIDI synthesis and compressed audio playback. These features extend the device to new, personalized forms of consumer utility. These functions not only add value to the user, but they also increase revenue opportunities for service providers.
