GPRS (English abbreviation: General Packet Radio Service, GPRS) is a technology that allows sending and receiving data faster than using Circuit Switch Data or CSD technology. The merging of cellular telephone services with GPRS (General Packet Radio Service) resulted in a new generation called 2.5G. The GPRS system can be used for data transfer (in the form of data packets) related to e-mail, image data (MMS), Wireless Application Protocol (WAP), and the World Wide Web (WWW). The emergence of GPRS was preceded by the invention of the 1G and 2G generation of mobile phones which then sparked the idea of the invention of GPRS. The discovery of GPRS continues to grow until the emergence of 3G, 3.5G, and 4G generations. The development of communication technology is caused by the desire to always improve the performance, capabilities and efficiency of the previous generation of technology. 1. Generation 1G: analog, low-speed (low-speed), enough for sound. Example: NMT (Nordic Mobile Telephone) and AMPS (Analog Mobile Phone System).
Personal Digital Cellular: The way it works is similar to TDMA, PDC is more widely used in Japan.
2. 2G generation: digital, low - medium speed. Time Division Multiple Access (TDMA): divides radio frequencies based on units of time. This technology makes it possible to serve several calls at once to make repetitions in certain time slices contained in one radio channel. Personal Digital Cellular: The way it works is similar to TDMA, PDC is more widely used in Japan. DEN: CDMA based technology with GSM architecture allows to open Private Mobile Radio and Push to Talk applications. Digital European Cordless Telephone: this technology based on TDMA is used for business purposes in the medium to large scale. Personal Mobile Service: this technology is not much different from DECT, the transmission speed is much faster and is used in a wider range of environments. IS-CDMA: This technology increases the capacity of the calling session by using a unique coding method for each frequency channel used. GSM: GSM technology uses a TDMA system with an allocation of approximately eight in one frequency channel of 200 kHz per unit time. The advantage of GSM is a high interface for providers and users.
3. 3G generation: digital, high-speed, for broadband. 4. 3.5G generation: enables faster internet access. 5. Generation 4G: is a Long Term Evolution (LTE), that is, the evolution of 3GPP and Ultra Mobile Broadband (UMB) technology comes from 3GPP2, so it is difficult to clearly distinguish between 3G and 4G technology. Example: Wimax Mobile Standard. GPRS is a packet-based transmission system for GSM that uses the principle of 'tunnelling'. It offers a higher data rate. Data rates are roughly up to 160 kbps compared to the 9.6 kbps that can be provided by GSM switched networks. Multiple radio channels can be allocated to a single user and the same channel can also be shared between users making it very efficient. In terms of cost, price refers to the volume of use. The user is charged in relation to the number of bytes sent or received, regardless of the call, thus it is possible that GPRS will be more likely to be chosen by the subscriber to access it over IP services. GPRS is a new technology that enables mobile communication network operators to offer data services at higher bit rates at lower rates, thus making data services attractive to the mass market. Overseas mobile communications network operators now see GPRS as the key to developing the mobile communications market into a new competitor in the land that was once owned by cable networks, namely internet services. This condition is possible because the explosion of internet use through cable networks (telephone) can also be done through mobile networks.
GGSN (Gateway GPRS Support Node): the gateway connecting the GPRS network to the internet network.
Mobile services that are now successful in the market are, weather reports, food ordering, sports news to daily important news. From these developments, the impact can be felt on the emergence of various competing HP providers offering increasingly affordable GPRS rates. In theory GPRS promises speeds ranging from 56 kbps to 115 kbps, thus enabling internet access, sending multimedia data to computers, ''notebooks'' and ''handheld computers''. This explains why at certain times and at certain locations GPRS access feels slow, even slower than CSD access which has a speed of 9.6 kbps. WAP is an abbreviation of Wireless Application Protocol which is a technology like WWW and is a protocol for accessing the internet through a cellphone, while GPRS (General Packet Radio Service) is a connection technology used by the cellphone to access the internet. For example, we use broadband on a PC that is connected to Speedy. GGSN (Gateway GPRS Support Node): the gateway connecting the GPRS network to the internet network. The function of this component is as an interface to PDN (Public Data Network), information routing, network screening, user screening, address mapping. SGSN (Serving GPRS Support Node): gateway connecting BSS/BTS network to GPRS network. This component serves to deliver data packets to MS, update subscribers to HLR, and register new subscribers. GGSN in charge of: 1. As an interface to external IP networks such as: public internet or mobile service provider 2. Updating routing information from PDU (Protocol Data Units) to SGSN. GPRS uses a packet switch communication system as a way to transmit its data. Packet switch is a system in which the data to be transmitted is divided into small parts (packets) and then transmitted and converted back into the original data. This system can transmit thousands or even millions of packets per second.
Transmission is done through PLMN (Public Land Mobile Network) using IP such as 08063464xxx. Because it is possible to use the transmission channel simultaneously by other users, the cost of GPRS access is, in theory, cheaper than the cost of CSD access. GPRS is designed to provide packet data transfer services on GSM networks at a speed that is better than GSM. This better speed is obtained by using a different coding scheme (CS) from GSM. To be able to use GPRS (especially on mobile phones that support it) you need to set it first. How to set GPRS contained in each operator. GPRS settings on HP can be done automatically and manually. GPRS settings can be done automatically by sending SMS to the provider you have, the rates vary between providers, and the format of the messages sent also varies depending on each provider. Meanwhile, for manual GPRS settings, it's enough to follow the instructions on the default settings found on the cellphone, without the need to change it again.
If you want to use your cellphone for Internet connection from a PC, you only need to set GPRS, without the need to set up WAP or MMS. Three things to know are the access point name, username, and password. Furthermore, to use GPRS on a computer, you can connect a mobile phone that has been set to GPRS with a computer that has been set up. Simply enter the dialing number for example 08096470 and click the dial button, then our request will be connected immediately. Currently, GPRS in Indonesia is unable to compete with 2.75G, 3G, 3.5G, and 4G technology which is a further development of GPRS. The 2.75G generation is known as the EDGE generation. EDGE was introduced by AT & T in the United States in 2003. Technically, EDGE has actually met the 3G standards set by the ITU. 3G technology is divided into GSM and CDMA. 3G technology is often referred to as mobile broadband because of its advantages as a modem for the internet that can be taken anywhere. The commercial development of 3G technology began in October, 2001, when NTTDoCoMo from Japan with W-CDMA technology sold its products for the first time on a limited basis. Then followed by SK Telecom, South Korea in 2002 with 1xEV-DO technology, followed by KTF from South Korea with EV-DO technology. The success of 3G services in these two countries is due to government support.
