GPRS Technology
GPRS (General Packet Radio Service) is the technology of the speed package radio transmission in the GSM network.
GPRS Benefits:
- High average data transmission is 20-40 Kb per second;
- GPRS service rates do not depend on how lengthy the connection was;
- Speedy and stable GPRS connection;
- Option to talk over the phone and exchange SMS messages with no need to disconnect GPRS;
- Efficient use of the power of your phone during the GPRS connection.
Specifics of GPRS
When using GPRS data is formed into packets transformed in parallel by a group of radio channels; radio channels may be used consequently by a group of users;
Voice calls enjoy the higher priority than the GRPS connection, therefore the transmission of data packets may occur only when radio channels are free from voice calls;
GPRS is adjustable with all most common protocols of the packet data transfer (TCP/IP, X.25 etc);
The speed of transfer of packet data depends on:
- The channel encoding scheme implemented in GPRS network (the MTS network applies the CS2 encoding scheme that ensures the speed of up to 13.4 Kb per second per radio channel);
- The amount of radio channels on receipt and transfer of data that can be simultaneously support the phone;
- How the network is busy where the data is transmitted;
- Quality of network where the data is transmitted.
GPRS-Equipment
To start using the GPRS services, you are required to hold a mobile phone supporting GPRS.
Ìîbile phones with the GPRS support are grouped into three classes:
- À Class Phones – voice call and data transfer may be performed simultaneously;
- B Class Phones – voice call and data transfer may not be performed simultaneously (during a voice call or SMS message the transfer of data packets is suspended to continue as the call ends or SMS message is received);
- C Class phones – phones support the transfer of data packets only.
