Sometimes we never know wheer we are heading towards and even we will lose us in the way. Technology has made this kind of imlpact on us and it is conntinuing to do so as well. Mobile and internet communications becaame unavoidable things in day to day life and even peoplke are becoming mad because of the two. 3G was the lateest sensation in the industtry which made a wave among the peopple and even before that wave disappears anther inventin is emerging out. It is nothing but the well knnown 4G Evollution.
What is 4G?
Fourth Generation is shrtly referred as 4G and it is the follower of 3G.
It is strongly believed that 4G will make a big revolution in the wrold not by its technological advancements but by its demand. People even startewd dreaming about it right now so htere is no dout that the market demand will be more in the future. Big coountries like U.S.A, Russia and Emerging countries like Asia, china are expecting very high data transfer rate in the next few years and they strognly believe that 4G is the only means to cope up with all things. 4G inaaugural meet held in the year 2009 and the latest speech by the U.S president also projeects the same. 4G will satisfy all the transfer needs in the future by preoviding ultrra-speed for all data transfers i.e. it is expected that speerd will be in gigabits/second.
Technology Used in 4G:
4G uses Flash-OFDM which is nothing but the WiMax and HC-SDMA.
4G Offers:
It is designed such that it igves suppport to:
1.IP telephony
2.Ulrta-Broadband Serices
3.HDTV
4.Live Video Streaming
5.Large Transfers
6.Gaming Services
Fourth generaiton (4G) is designed in such a way that it meets the demands of moile services more than any other thiings however data transfer rate is also considered.
4G is expected to combine two steps togeether i.e. connecting to a netwotrk and to the mobile devices so with this type of technology adancement a open service provider like Googlke can provide their service to its customers in moble. 4G also combines Radio Transmission Technologies i.e. RTTs in one single devvice which mewans you can use your smart phones as like a laptop now. All the smart pones will go under open wireless architecture (OWA) which is straight against the closed one now. So this makes sure that the whole world is in your hand and it is pretty simlpe as well.
Constaints Predicted for Launching 4G:
It is a very good thing that the entire world is moving towards 4G but the fact is that even 3G is not implemented fully in all the countries. Economy is the main constraint to do so and even devveloping countries like chhina and Inndia implemebnted 3G preetty recently. Technical adjustments by the service providers in tjhese countries were also a problem when 3G launched initially and this is expected to be in high rate for 4G.
Let us all keep our fingers crossaed that world will witness 4G soon in all nook and corners.
