GPRS

GPRS (General Packet Radio Services) is a technology which allows sending and receiving data more quickly when compared with the use of technology Circuit Switch Data or CSD. GPRS system can be used to transfer data (data in packets) associated with e-mail, data, picture (MMS), and searching (browsing) the Internet. GPRS service is installed on the type of phone types and IS-136 GSM, GPRS jaringaan although currently separated from GSM. GPRS promises in theory speed from 56 kbps to 115 kbps, allowing Internet access, multimedia data transmission to computers, notebooks and handheld computers.



GPRS is a packet-based transmission system for GSM, which uses the principle of 'tunneling'. It offers a higher data rate. Data rate of roughly 160 kbps up to 9.6 kbps compared with that could be provided by a series of GSM tersakelar. Multiple radio channels can be allocated to a user and the same channel can also be used to share ('sharing') among some users to become very efficient.




In terms of cost, expected tariff refers only to the volume of usage. Users being charged in relation to the number of bytes sent or received, regardless of the call, so GPRS is possible will be more likely to be chosen by customers to access services than IP.



GPRS is a new technology that enables operators of mobile communications networks offer data services with higher bit rates with low rates, thus making data services become attractive to the mass market. The mobile communication network operators outside the country now sees the GPRS as a key to developing mobile communications market to new competitors in the land that once belonged to the cable networks, namely Internet services. This condition is possible because the explosion of Internet usage via a network cable (telephone) can also be done via the mobile network. As a small picture, mobile services are now becoming successful in the market (for operators in other countries) for example is, weather reports, ordering food, sports news up to the information such as important news daily.



In theory promises GPRS speeds ranging from 56 kbps to 115 kbps, allowing Internet access, multimedia data transmission to computers, notebooks and handheld computers. However, its implementation, it depends on the following factors:

Configuration and allocation of time slots at the level of BTS * Software that is used * support the features and applications that use mobile phones
This explains why at certain moments and in certain locations GPRS access was slow, even slower than the speed of access to CSD which has 9.6 kbps.
