3G White paper
The telecommunications world is changing as the trends of media convergence, industry consolidation, Internet and Internet Protocol (IP) technologies and mobile communications collide into one. Significant change will be bought about by this rapid evolution in technology, with Third Generation mobile Internet technology a radical departure from that that came before in the first and even the second generations of mobile technology. Some of the changes include:
• People will look at their mobile phone as much as they hold it to their ear. As such, 3G will be less safe than previous generations- because television and other multimedia services tend to attract attention to themselves- instead of hands-free kits, we will need eyes-free kits!
• Data (“non-voice”) uses of 3G will be as important as and very different from the traditional voice business
• Mobile communications will be similar in its capability to fixed communications, such that many people will only have a mobile phone
• The mobile phone will be used as an integral part of the majority of people’s lives- it will not be an added accessory but a core part of how they conduct their daily lives. The mobile phone will become akin to a remote control or magic wand that lets people do what they want when they want ....details

   
               
     

GPRS Traffic Model

A traffic model for GSM/GPRS, the hybrid radio resource allocation (HRRA) algorithm is evaluated. A dedicated number of GPRS channels plus idle periods between voice calls are used for GPRS data packet transfers. A simulator was developed in order to evaluate the HRRA algorithm, which provides a reas onable forecast on the voice blocking probability and on packet delay for a single cell system. Since the major issue is the correct resource allocation, results are shown for the influence of some choices and assumptions on the overall system performance. As expected, blocking probability can reach very high values if the number of dedicated channels increases too much. For the specific case of 4 carriers and traffic of 20 Erl, 4 channels dedicated to GPRS still enable an affordable blocking probability, leading to a mean packet delay of 15 s. The results can be used to illustrate the fundamental options that need to be taken by an operator, when implementing GPRS. ....details
