Vol-10 | Difference between 2G and 3G

2G and 3 G is a family of standards for mobile telecommunications defined by the International Telecommunication Union, which includes GSM EDGE, UMTS, and CDMA2000 as well as DECT and WiMAX. Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment.

2G Stands for second generation mobile telephony standards, where 3G defined the third generation  mobile telephony standards to facilitate growth, increase bandwidth, and support more diverse applications. For example, GSM (the current most popular cellular phone standard) could deliver not only voice, but also circuit-switched data at download rates up to 14.4 kbps. But to support mobile multimedia applications, 3G had to deliver packet-switched data with better spectral efficiency, at far greater bandwidths.

History

·  Launched a decade apart, 2G and 3G technology were both utilized in divergent parts of the world first. 2G first launched in the nation of Finland in 1991, while 3G was first used in Japan in 2001, according to UMTSWorld.com, a website that follows 3G technology.

Function

·  While 2G networks primarily involve the transmission of voice information, 3G technology provides the additional advantage of data transfer. 3G can download information at 14 Megabits per second, while uploading 5.8 Megabits per second.

Significance

·  3G technology offers a higher level of security than 2G networks. According to Colin Blanchard of BTexaCT, a UK-based technology firm, 3G networks allow authentication procedures when communicating with other devices.

Considerations

·  Due to the advancements of 3G technology's data transfers, many additional features are available to those networks utilizing the system, unlike 2G. These features include mobile TV, video transfers and GPS systems.
