GPRS - a set of packet radio data technology (General Packet Radio Service) in GSM networks. In GPRS mode, the information is divided into small packets and then transmitted simultaneously through multiple communication channels. When this channel is busy, it is only used during data transmission, but not always, like with other forms of network access. The main advantages of GPRS technology include: Subscriber continuously connected to the network and does not waste time establishing a connection. It is no longer necessary to dial the remote access server every time you need to exchange data; Connected to an IP network with the GPRS unit is always ready to send/receive information. High-speed data transmission. Nowadays, GPRS technology provides access speed four times higher than the standard rate on the GSM network. The connection speed depends on the GPRS class module, the quality of the cellular communication, and the load; Opportunity to pay only the total amount of transferred/received information regardless of the time spent in the compound; Ability to make and receive calls and SMS messages while in the compound. The only exceptions are periods of data exchange, as at this time the module is busy receiving/transmitting information. This restriction is imposed by modern phones supporting GPRS class.
