The Trend of GPRS DevelopmentThe Trend of GPRS DevelopmentThe Trend of GPRS DevelopmentThe Trend of GPRS Development
1. GPRS handsets supporting MMS have developed very fast (PDA, camera, Midi will emerge largely by the end of 2002 year).
2. Web browsing and e-mail are oriented towards wireless access.
3. Existing network will suffer bottlenecks as the need for data increases.
4. New services have increased the income for operators. The profit created by SMS has reached 33% of the total profit.
5. GPRS may accumulate experience for 3G operating and mobile data application.
6. GPRS network supports smooth evolution to 3G to protect the operators’ investment.

MMS may be the “Top Application”MMS may be the “Top Application”MMS may be the “Top Application”MMS may be the “Top Application”
1. SMS has become a very important source of income and profit.
2. The bottleneck of SMS application is the input method – keyboard input method is so inconvenient.
3. By adding voice and pictures to short message, MMS also simplifies the input method.
4. With the evolution of mobile phone and network equipment, it is time to develop with large steps.
These opinions have been strongly supported by experts all over the world during this year.
