GPRS NetworksGPRS (General Packet Radio Service) is a technology that allows sending and receiving data more quickly compared with the use of technology Circuit Switch Data, or CSD. This uses GPRS technology, 2.5 G GPRS system can be used to transfer data in the form of packages associated with e-mail, data, pictures (MMS) and browsing the Internet.

GPRS service is installed on the type of mobile phone GSM and IS-136, although the current GPRS network separate from the GSM. GPRS is a packet-based transmission system for GSM, which uses principles of 'Tunneling'. It offers a data rate that is higher. Data rate up to 160 kbps. This chanel is used together with other users, so more efficient. In terms of cost, only to the volume of use.

Cost issued by the user depending on the number of bytes of data sent or received, without considering the many calls and user used this service. GPRS is a technology that allows the operator to offer mobile communication network and data service with bit rate higher with the low tariffs, making the data services become attractive to consumers.

The communications network operators now see the move GPRS as a key to developing mobile communications market into new competitors in the land that was once owned cable network, namely, internet services.

This condition is possible because the explosion of the Internet through the network cable (the phone) can also be done through the network move. As an illustration, a small, mobile services which has become successful in the market, for example weather reports, ordering food, sports, news and information to such important news daily.

In theory promises to GPRS speeds ranges from 56 kbps to 115 kbps, allowing Internet access, multimedia delivery data to the computer, notebook faster than dialup connection. This explains why in certain time and access to certain locations in GPRS very slow, even slower access from the CSD, which has 9.6 Kbps speed.

This may be because the channel is used simultaneously so that the bandwidth received a little more. The rapid growth of mobile communications to encourage the operators services to enrich the race in order to increase the range of services income for the company while still maintaining customer assets.

Mobile data communications, mainly for Internet access, it appears now become the main force. The introduction of WAP (Wireless Application Protocol) has shown potential as a wireless Internet service.

WAP is a global open protocol that allows users to access services on-line from the small screen on the mobile phone using built-in browser. WAP work on various mobile network technology, which Mass market allows for the creation of mobile data services.

Now that needed a technology that is able to provide faster access and The ability are always connected to the network (always' on '). Overview that this would attract the operators. Here is a GPRS offers solutions for demand technology as mentioned above, namely, can to give the operators the opportunity to provide more data services efficient and the data rate higher and introduce services new to compensate for the decline in communications costs per minute.

Obviously, GPRS allows customers to create the phase relationship faster, stay connected permanently, using the speed of data more high and only pay the cost of each bit is transferred only. Consider clearly, that the trend of the market would not lead to any technology which is precisely to increase the cost or subscription rates.

In addition, all technology related to new services that will be marketed able to be implemented in the tools high volume (many used so that it can be produced large-scale) that the price cheap, such as phone The move is very simple and two-way radio call.
