What is 4g Mobile Technology?
4G mobile technology is the name given to the next generation of mobile devices such as cell phones. It became available from at least one provider in several parts of the US in 2009. There is not yet an agreed industry standard for what constitutes 4G mobile, so for now it is merely a marketing term. The use of G, standing for generation, in mobile technology covers the major advances of the past 20-30 years. 1G technology involved the first widely available mobile phones. 2G technology, which began in the early 1990s, switched to a digital format and introduced text messaging. 3G technology improved the efficiency of how data is carried, making it possible to carry enhanced information services such as websites in their original format. The latest iPhone is the best known example of 3G technology. 4G mobile is not yet established as an agreed set of standards, so its features are currently simply goals rather than requirements. As well as drastically increasing data transfer speeds,
In the present mobile world, the most used technology is 2G (GSM) technology. However, it has a very low data transfer capability. And therefore, it limits users from using features such as video conferencing, music and video downloads. To increase the data transfer application capability — new technologies are being evolved. The first 2.5G (GPRS) came into picture and then the 3G mobile technology (WCDMA). In 3G technology, it allows the maximum data speed of 2Mbps. However, the most advanced technology, i.e., 4G is in its infancy is suppose to provide data transfer speed of 100Mbps in future. Many companies are working on this technology and we are hopeful that in the recent future, mobile technology will definitely reach a new height.
