How Does 3g Work?

3G is the short form used for third-generation technology. It is used in the reference to mobile phones standards. 3G gives the ability to transfer both voice as well as non-voice based Data at a much faster level. While marketing 3G services, video telephony is famously referred as a killer application.

3G networks have not been upgraded from 2G networks and do not function on the same frequency spectrum. For 3G services new networks need to be fitted and new frequencies are allocated to the mobile operators.

The first country to start 3G service on a great scale was Japan. Around 2005 nearly 40% of consumers used 3G network only. With 2G technology becoming outdated in Japan, it is expected that by 2006 the remaining percentage of 2G networks shall be shifted completely to 3G networks.
