GPRS Glance

GPRS is a packet-based transmission systems for GSM that uses the principle of 'tunneling'. He offers a data rate higher. Data rate of roughly 160 kbps up to 9.6 kbps compared with that provided by the circuit tersakelar GSM. Radio channels can be allocated to multiple users and a similar channel can also be used to share between users, so be very efficient. In terms of cost, the price refers to the volume of usage. Users being charged in relation to the number of bytes sent or received, regardless of the call, thus it is possible GPRS will be more likely to be chosen by customers to access services than IP.

GPRS is a new technology that enables network operators to offer mobile communication services with data bit rate higher with lower tariffs, thus making data services become attractive to the mass market. The mobile communications network operators overseas GPRS is now seen as 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 use of the Internet boom through cable network (telephone) can also be done through mobile networks. Mobile services are now successful in the marketplace is, weather reports, ordering food, sports news up to the important news daily. Of these developments, the impact can be felt in the emergence of HP berbeagai competing providers offer GPRS tariffs are increasingly affordable.

In theory promises GPRS speed from 56 kbps to 115 kbps, allowing Internet access, multimedia data transmission to a computer, [[the notebook]] and [[handheld computer]]. However, in implementation, it depends on the factors as follows:

* Configuration and allocation of time slots at the level of BTS
* Software used
* Supported 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 access speed of CSD, which has 9.6 kbps.

Differences GPRS and WAP

WAP stands for Wireless Application Protocol is a technology like the WWW and a protocol to access the Internet through cell phones, while the GPRS (General Packet Radio Service). is the connection technology used by HP is to the Internet. For example, we use broadband on a PC connected to Speedy.

Main components

The main components of the GPRS network is:

* GGSN (Gateway GPRS Support Node): gateway GPRS network link to the Internet network. The function of this component is as an interface to the PDN (Public Data Network), information routing, network screening, screening users, address mapping.
* SGSN (Serving GPRS Support Node): a network connecting gate BSS / BTS to the GPRS network. This component serves to deliver data packets to the MS, the HLR updates the customer, new customer registration.
* PCU: BSS-level component that connects the terminal to the GPRS network
