The terms surrounding the PHONE

Some of the terms or knowledge about the cell phone you need to know, to help you understand the specifications of the phone:

1G

1 G is the abbreviation of the first generation cellular phonetechnology, the analog technology. Currently Phone / Mobile The first generation was very outdated. Marked with a bad connectionconversation, lack of security and low capacity. However, the firstgeneration of mobile phones is still a large contribution becauseof where the embryo of more sophisticated mobile phonescontinues to grow! Example 1G technology is AMPS, TACS and NMT.

2G

2G (or 2-G) is short for second generation mobile phonetechnology that is renewing the first generation in the field ofdigital technology, which in theory is basically a renewal in thefield of data transfer. Cellular technology is present replace the first cellular technology, which uses 1G analog systems such asAMPS (Advanced Mobile Phone System). 2G is a cellulartelecommunication network was commercially launched on the GSM standard in Finland by Radiolinja in 1991. Unlike the 1G,2G uses digital system. 2G offers superior sound quality with high bit rate, and can serve text communication, namely SMS. Examples of 2G technology is GSM (using protocols CSD,HSCSD, GPRS and EDGE) and cdmaOne.

2.5G

2.5G Cell Phone / Mobile 2.5G generation of transition between 2Gand 3G technology, offering data transmission capacity than needed, thus improving data services such as GPRS. GPRSallows network providers to charge based on the amount of data sent rather than the length of connection time. Examples of 2.5G technology is the use of GPRS in GSM.

3G

Third generation mobile phone networks. evolution of the GSM standard which allows data transfer faster broadband. This term is generally used refers to the development of wireless telephonetechnology (wireless). Created and use of this specification basically only speed up the transfer of data on digital cellular technology. Examples of 3G technology is EDGE on GSM, UMTS andCDMA2000 1x.

4G

4G (4th Generation) is a fully integrated IP-based systems. This will be achieved after wired and wireless technologies can beconverted and able to generate speed 100Mb / s and 1Gb / seither inside or outside a lounge with premium quality and highsecurity. 4G will offer all kinds of services at an affordable price.Each 4G handset will automatically have an IP number v6 comes with the ability to interact with the internet telephony basedSession Initiation Protocol (SIP).
