3G Technology - Promises and Challenges
Introduction
Imagine a situation where you are about to make an important
Sales Presentation. You realize that you have brought the wrong
presentation slides and you call up your colleague. She
immediately emails the file to your 3G terminal and you transfer
it to your laptop. Another scenario is having video-conferencing
and sending character-based messages simultaneously with your
clients. With 3G, the possibilities for wireless applications
are numerous. For instance, imagine calling up a map in your
car, conducting a video conference over wireless phones,
checking e-mails, and browsing the web - wirelessly.
