 GSM MOBILE DATA NETWORKS – GPRS/UMTS

 

The GSM mobile network is evolving from a pure telephony network to a combined voice and data network. GSM is and will be increasingly used to access the Internet and the Corporate Intranet.

To achieve that goal, the GSM network technology is changing with the introduction of  new data oriented technologies such as WAP (Wireless Application protocol)to provide the Internet connectivity to mobile terminal.
 The GSM core network technology is also evolving with the introduction of a new  packet switched core network : the  GPRS (General Packet Radio operator Services) specialized in the data routing inside the GSM network or to an outside data network as the Internet or Intranet. GPRS will be used also in the UMTS network and serves as the foundation for the multimedia services
