what is gprs?

Question

how can I use it?

Answer 1

I'm not sure which GPRS you mean. Bittu's answer above is correct, if that is what you meant. But if you mean GPRS as a communication protocol, these might help:

"Short for General Packet Radio Service, a standard for wireless communications which runs at speeds up to 115 kilobits per second, compared with current GSM (Global System for Mobile Communications) systems' 9.6 kilobits.

"GPRS, which supports a wide range of bandwidths, is an efficient use of limited bandwidth and is particularly suited for sending and receiving small bursts of data, such as e-mail and Web browsing, as well as large volumes of data."

(From: http://www.webopedia.com/TERM/G/GPRS.html)

"The General Packet Radio Service (GPRS) network is an "always on", private network for data. It uses the existing GSM network to transmit and receive TCP/IP based data to and from GPRS mobile devices. Private IP addresses are typically dynamically assigned within the network to mobile devices. However, Access Point Names (APN's) provide a gateway route to other networks such as the Internet, WAP services or private corporate networks. Firewalls typically reside at the APN to isolate the public and private networks. IP addresses allocated to mobile GPRS devices are therefore not addressable from outside the GPRS network (e.g. from the Internet) without specialised services or infrastructure."

"The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS works on GPRS cellphones as well as laptops and portable devices that have GPRS modems. Users have typically experienced downstream data rates up to 80 Kbps. GPRS is not the same as GSM's short messaging service (GSM-SMS), which is limited to messages of 160 bytes in length. GPRS was superseded by EDGE."
