as a service for users that manage production, energy generation, distribution and similar systems in the process industry.
The implementation of this service allows the user to control, remote control and automation, central and peripheral parts of the complete supervisory control system.
The biggest advantage of this service is shown in process systems where the central and peripheral parts of the system separate larger geographic distances, a need exists for centralized management and control.
GPRS technology, as the technology of data transmission to fully meet this requirement, and provides a very smooth and efficient communication services based on the Internet and TCP / IP protocols are available through the local area network and a network of public mobile telephony.
GPRS (General Packet Radio Service) is an Internet / IP data service GSM technology and as such is closely related to the GSM service.
As a rule, the service is available in all geographic areas covered by GSM signal selected GSM network service provider.
Speed ??of data transfer via GPRS technology is far greater than the speed achieved by the GSM during transmission (data transfer).
Unlike GSM data transfer whose maximum speed is 9.6 kbps, GPRS can theoretically achieve speeds, data transfer.
The theoretical maximum is 53.6 kbps, but those are usually close to 40 kbps speed which is more than enough to be a relatively quick amount of data transfer required in supervisory control systems.
One of the very important difference GPRS technology in relation to other data transfer technology is that the GPRS technology for transmitting data using a constant Internet connection, which guarantees a short access time, whereas eg GSM data transfer using traditional modem dial up on demand access to data.
As GPRS technology, for normal operation, requires ongoing access to the Internet, the cost of data transfer are not accounted for by the time spent to access the Internet according to the amount of the uploaded data.
This fact greatly favors the selection of GPRS technology in relation to any data transmission technology based on dial-up access and billing for the duration of data transfer.
In addition to cost control data that can be effectively carried GPRS technology, the price of the transferred data is infinitely more convenient than the data transfer via GSM services or other fixed telephony services.
GPRS is based on packet data transfer, so that the IP connection between the GPRS network and external data networks realized unhindered access to other networks for packet data transmission, such as the Internet or LAN.
The application of Internet technology combined with GPRS technology provides ease of information exchange, management of individual parts of the system and more efficient use of the system in virtually all weather and geographical conditions.
It is important to note that the efficiency of the system explicitly depends on the GSM operator, so that the development of quality GPRS service providers offer, systems that rely on GPRS communication can expect better performance, lower pricing and availability of the GPRS service.
