GPRS

GPRS (acronym in English: General Packet Radio Service, GPRS) is a technology that enables the sending and receiving data faster than the use of technology Circuit Switch Data or CSD. Merging cellular phone service with GPRS (General Packet Radio Service) to produce a new generation of so-called 2.5G. GPRS system can be used to transfer data (in the form of data packets) are associated with e-mail, data, picture (MMS), Wireless Application Protocol (WAP), and the World Wide Web (WWW)....

The appearance was preceded by the discovery of GPRS mobile phone 1G and 2G generation which then sparked the idea of finding the GPRS. GPRS discovery continues to grow until the emergence of next generation 3G, 3.5 G, and 4G. The development of communication technology is caused by the desire to always improve performance, capability and efficiency of previous generation technology. 1. Generation 1G: analog, low speed (low-speed), enough to vote. Example: NMT (Nordic Mobile Telephone) and AMPS (Analog Mobile Phone System). 2. Generation 2G: digital, low speed - high. Example: GSM and CDMA2000 1xRTT. 2G is a cellular telecommunication network launched commercially in GSM in Finland by Radiolinja in tahum 1991.

* Time Division Multiple Access (TDMA) based radio frequency dividing unit time. This technology allows to serve multiple calls at once, doing repetitions in a given time slice contained in a single radio channel.
* Personal Digital Cellular: How it works is similar to TDMA, PDC is more widely used in Japan.
* IDEN: CDMA-based technology with GSM architecture allows for open applications and Private Mobile Radio Push to Talk.
* Digital European Cordless Telephone: TDMA-based technology is used for business purposes in the middle to upper scale.
* Personal Mobile Secvice: This technology is not much different from the DECT, the transmission speed is much faster and used in a wider environment.
* IS-CDMA: The technology is improving the capacity penelponan session using a unique coding method for each frequency channel is used.
* GSM: GSM technology using TDMA system with allocation of about eight in a single frequency channel for 200kHz per unit time. The advantages of this GSM is the high interface for the providers and users.

3. Generation 3G: digital, high speed (high-speed), for broadband (broadband). Example: W-CDMA (also known as UMTS) and CDMA2000 1xEV-DO.

4. 3.5 Generation G: allows access to the Internet faster. Example: HSDPA.

5. Generation 4G: a Long Term Evolution (LTE) ie, the evolution of the 3GPP technology and Ultra Mobile Broadband (UMB) derived from 3GPP2, making it difficult to distinguish clearly between the 3G and 4 G. Example: Wimax Mobile Standard.
