What is 3G and how it works

Everyone understands that in this age of high technologies information and the speed of its transfer is one of the crucial factors defining our hectic life. Of course, not so long ago we could hardly imagine that staying at home alone we could easily communicate with friends, exchange information and even make money or manage our own business without leaving the house. Internet made it all possible. And now all this is becoming accessible from anywhere, not just from our home. As we all know the progress does not stand still, and not long ago a completely new invention came into the world – the mobile communication standard of the third generation. It is really the next generation of cellular communications with advanced possibilities of mobile services including high quality voice calls, video calls, broadcasting of television programs, transfer of fax messages and data to any subscriber, electronic mail, games, various information services, roaming and many other features.
Let's see what makes this new standard of communication different from its predecessors. The major distinction is that the third generation systems (that have already been introduced in many countries of the world) provide higher speeds of data transfer. Besides, such technology is mostly packet-oriented and represents a means of easy and relatively inexpensive Internet connection. According to surveys made by the system's developers, most probably 3G will become the major way of internet data transfer in the future.
Of course, the current state of development of the third generation mobile networks does not allow us to determine the time in the future when the technology will be accessible for every person from anywhere. We can say for sure only that for a pretty long time in the future the new technology will function in conjunction with the second generation systems, as the introduction of new technology will require a lot of time and money. Owing to the fact that the range of services offered by 2G and 3G is different we can be sure they will not become competing structures and, quite the contrary, will supplement each other.
Other experts believe that it's too early to speak of any possibility of mass usage of this type of communication. However trite it may sound, the reason of it is the cost of equipment. Besides, the cost of the services provided by 3G operators is somewhat higher than the ones provided by the existing 2G carriers. All this may lead to lower demand than it was expected before.
At present there are only two standards of the third generation mobile communications: UMTS which is very popular in Europe and CDMA2000 having supporters in Asia and USA. These systems are based on different approaches to the organization of communication.
One thing is clear: the Internet and high-tech mobile technologies are the things of the future. It is possible that in a few years the usual system of cellular communications will change drastically and transfer of large amounts of data will take mere seconds. Till then, let's enjoy the discovery of the new revolutionary services being introduced in newly created third generation networks.
