The history of 3G network

The technology is evolving rapidly. The mobile phones technology, for example, recorded a sharp rise in prices. The emergence of 3G technology makes Internet fully available on any 3G phone and allows a variety of personal broadband and business functions is possible.

Identification
The 3G network is the next generation of mobile technologies, reaching the phones to connect the transfer speed comparable to a computer to a broadband network. It is, 3G enables data transfer speed 2.4Mbps, almost, that provides the experience of mobile data next to the computer via cable modem speed. In this way, users of mobile phones can play videos, you can enjoy the 3-D games and business users the ability to work in real-time videoconferencing to provide, where they can get a signal.

Calendar
A 3G network or a TD-CDMA (Time Division --- Code Division Multiple Access) or a W-CDMA (Wide --- Code Division Multiple Access) network. The TD-CDMA has come before, it was primarily designed to move data. TD-CDMA allows you to make phone calls, but includes an advanced W-CDMA voice / data capacity, which is why W-CDMA 3G service is preferable. Siemens made the first call from a 3G phone, March 29, 2000 compared to a TD-CDMA network. A Japanese company NTT DoCoMo is the first company to introduce a W-CDMA 3G network established, where they presented their study on the 3G network in June 28, 2001. On October 1, 2001, NTT DoCoMo has finally been the first commercially available 3G WCDMA network in the press in Japan. The international appeals of 3G was first made between Madrid, Spain, and Tokyo, Japan, December 19, 2001.

Geography
3G W-CDMA in the United States appear until early 2005 when Verizon Wireless finally has a W-CDMA 3G network, and began selling products to gain access to the network. AT & T and Sprint followed and began with the products of 3G network in the same year. However, 3G is really only in broad sectors of the population. For 3G, the mobile operators must offer all new radio equipment installed in turn, slows down to preserve the availability of 3G services in rural areas of the United States.

Importance
E 'was estimated that the number of active mobile phones in the world of 2000 was almost 800 million units) (see Resources. As this amount, the number of active mobiles grew up. The 3G network is required to provide bandwidth needed to require all broadband applications, users will be developed as a mobile technology and space moves forward.

Considerations
UMTS is the next stage of 3G technology, the transition between a 3G network, which enables a new generation 4G network. On March 1, 2004, Nortel Networks has broken the seal on the transition to 4G, when the first UMTS calls using satellite positioning equipment, Nortel and Qualcomm, Motorola and UMTS mobile phones.
