What is a 3G phone?
A 3G phone is one that can use 3G networks. 3G is an abbreviation for ‘third generation cellular technology’, the ‘first generation’ having been analogue cellular, and the ‘second generation’ being today’s digital cellular networks. 3G supports very high-speed data services over a cellular network. In fact, multimedia 3G networks transmit wireless data up to 2 Mbps. 3G mobile phones offer high-speed Internet connectivity using Universal Mobile Telecommunications System—the technology of choice for third-generation wireless service delivery.

Why do we need 3G phones?
3G will support bandwidthhungry applications such as full-motion video, videoconferencing and full Internet access.

Where has 3G been deployed?

3G has been deployed in all the developed nations, as well as in Pakistan, Vietnam, Thailand, and several other countries. India is still awaiting the TRAI’s recommendations on 3G.

Who was responsible for the development of 3G?
3G is an initiative of the International Telecommunications Union (ITU). The World Administrative Conference (WAC) assigned 230 MHz of spectrum at 2 GHz for multimedia 3G networks.

When did 3G first appear on the scene?
3G network trials started in Japan in 2001.

How do 3G-enabled devices operate?
3G-enabled devices send and receive radio signals to and from base stations. The base stations are low-power radio transmitters—each providing coverage to a cell. Cells need to overlap to enable seamless coverage.
