What will 3G mean for you
3G is short for third-generation mobile telephony services. 3G guidelines will revolutionise the country's cell phone services, clearing the way for high-speed mobile connectivity in India.
3G phones work in higher bandwidths of 15-20 MHz. Currently, mobile phones work on 2G or 2.5G, and use 30-200 KHz bandwidth. Bandwidth is a measure of the width of a range of frequencies used while transferring data from one point to another and is measured in hertz.
How do 3G services help us?
3G services enable video broadcast and data-intensive services such as stock transactions, e-learning and telemedicine through wireless communications
All telecom operators are waiting to launch 3G in India to cash in on revenues by providing high-end services to customers, which are voice data and video enabled. India lags behind many Asian countries in introducing 3G services.
Packet-based data provides several advantages over the existing circuit-switched techniques used for carrying mobile voice. It allows higher call volumes and support for multimedia data applications, such as video and photography.
Users will be charged on how much data they transmit, not on how much time they are connected to the network, because with 3G you are constantly online and only pay for the information you receive.
