What is 3G?

The latest buzzword in the Telecom industry in India is 3G. While we have been hearing and reading about 3G almost every day, I thought of just brushing up with what exactly 3G is.

3G refers to the third generation of developments in wireless technology. It is a collective term for the new communication procedures, standards and devices that will improve the speed and quality of services on mobiles. 3G-compatible handsets combine the functionality of a mobile phone with that of a PC and a personal organiser/PDA.

How does 3G work?

3G divides each call or transmission into little packets of data, marking each one with an individual code to show which connection it belongs to. This is a more efficient way of transmitting data, allowing 3G networks to deliver larger files, like pictures and video, at much faster speeds.

What are the benefits of 3G?

Besides phone calls, 3G allows fax transmissions, e-mails, including large attachments, while on the move. High-speed internet access allows web browsing and fast downloading of data files, software, and image or music files. 3G can be used for video conferencing and some 3G handsets can also function as personal organisers, with electronic diaries, contact lists, and automatic reminders. Most 3G networks offer global roaming.
