3rd Generation Technology
3G is a new mobile standards and technology that will eventually replace 2G communication in the future. It conform the International Telecommunication Union family standard which offer wider range of more advanced services such as video call. In October 1, 2001 NTT DoCoMo was the first company to launch commercial W-CDMA network followed by South Korea.
Transition from 2G network to 3G was not easy in fact most of the countries have not completed the transition of 2G to 3G. The main problem faced by them is the cost to build an entirely new system to support 3G with an exception in US where 3G and 2G can operate within the same frequency hence cost is greatly reduced.
With the high speed data transmission, data and files can be downloaded to a computer via 3G connection in a short period of time. This can be done by connecting a 3G phone or data card to a computer.
The world is expected to reach full migration to 3G network by 2020.
