Compare to 2G and 2.5G mobile communication

trend of 3G mobile communication technology complexity grows in the form of exponential. At the same time of sharply increasing technology complexity

the problems of technology diversity

and all kinds of new services must be considered when we construct 3G mobile communication network. In this text

we will start at smooth evolution

roaming switch

network programming and network optimization these hot topics

analyse the effect on present 2G mobile communication network operation caused by construction 3G network. Based on the remarks above. We will do our prospect on the future development and construction of 3G network.
