The main advantages of GPRS
GPRS - a system that implements and supports the protocol packet information within a cellular network. If packet data transmission channel is engaged in relevant only in the transmission of information, it allows to achieve greater efficiency in its use. The most tangible benefit is the transfer of data and the output of the global network Internet.
When using GPRS system information is collected in packets and transmitted in the air, they fill those "empty" (not used in the present channel traffic), which is always in the transmission of voice information. If during normal transmission of data connection is established first, and only then starts data transmission, then the packet transfer phase connection is practically absent. Herein lies the fundamental difference between the packet data. As a result, more efficiently use network resources and an opportunity to more profitable for a subscriber charging, based not on the duration of connection, and the amount received and transmitted information. In networks that support GPRS, provides for a phased way to increase data transfer speed, in the limit of GPRS can provide speeds up to 115 kbps. To date, the main limitations associated with the possibilities of user terminals. GPRS-terminals of the first generation will ensure the transfer of information at speeds up to 53.6 kbit / s and reception - at speeds up to 26.8 kbps.
