What is GPRS ?
GPRS extends the capabilities of existing GSM networks and enables higher data rates and longer messages. It is a packet based data service for TDMA and GSM networks which enables the transition towards 3G. GPRS was designed to make mobile data faster, cheaper, and user-friendlier than ever before. By introducing Internet Protocol (IP) and packet switching to mobile networks, it gives mobile users faster data rate and particularly suits bursts as in Internet and intranet traffic. For subscribers, GPRS enables voice and data calls simultaneously. Setting up a Connection is almost instantaneous, and users can be always connected to the mobile Internet, enjoying Web surfing, high-speed delivery of e-mails with large file attachments, and access to corporate LANs. GPRS was defined by the European Telecommunications Standards Institute (ETSI) as a mean of providing packet radio service on GSM radio networks. At the same time, carriers whose networks were based on North-American TDMA have de
The world of mobile phones is changing, daily it seems. All the rage these days is 3G, third-generation telephony, such as mobile Web browsing and other advanced functionalities. These 3G protocols are manufactured on the building blocks of 2G technologies, which were themselves revolutionary when they began to be used widely. In between these two technologies is General Packet Radio Service (GPRS). GPRS is a series of functionalities that allow mobile data streaming and transfer to users of Global System for Mobile Communications (GSM) mobile phones. GPRS is sometimes called 2.5G, since it predates 3G but is more advanced than 2G. GPRS also boasts communication speeds of up to 115 kilobits a second, a vast improvement over the GSM standard of 9.6 kilobits a second. GPRS allows multiple users to share a transmission channel by opening the transmission for transfer only when each individual user needs it. Very few users need always-on data transfer capability, so GPRS works for a vast m
