The supplement comes GPRS GSM, adding a system based on packet data transmission to the existing network. The process is made quite simple with respect to what one would expect, being only necessary to add some elements to the existing infrastructure and an "upgrade" from the "software" used in the network.
In an IP system, data is divided into packets that are sent separately. Information travels through the network until it reaches its destination, and is reconstituted there and presented in its original form. All the parts are related to one data with others, but the way they travel and are grouped varies. This enables more efficient use of radio spectrum available, because not be necessary for a radio channel is used exclusively for transmission from one point to another. The packages, when traveling, using the available frequencies, which allows large numbers of GPRS users can share the same bandwidth and the same cell.
The use of IP protocol enabling direct Internet access from mobile phones. Mobile networks will use the same data transmission system that the Internet, allowing all services currently available "online" can be accessed on a mobile terminal without the need for a simplified language as used in the WAP . Because of this, every GPRS mobile may have its own IP and straighten the network will be identified by that number.
The GPRS also allows more efficient use of GSM network and distributes it uses more efficiently the available radio frequencies, allowing the users have a permanent connection (despite not being engaged). At the same time ease the data transmission in GSM and SMS as part of the information used by these systems will be transmitted through the GPRS system.
