It not only enables them to be used worldwide, but also provides with better bandwidth and increased speed. This technology is also comfortable to work with 2G technologies.
The main aim of this technology is to allow much better coverage and growth with minimum investment. Figure: Evolution of Mobile system from 2G to 3G. Difference between 2G and 3G Technology.
The network construction and maintenance of 3G is much costlier than 2G networks. Also from the customers point of view the expenditure for 3G network will be excessively high if they make use of the various applications of 3G.
By the early 90s, 2G 2nd Generation mobile networks were commercially launched. With further innovations in technology, 3G networks started rolling out back in , gradually overlaying but not replacing the 2G networks.
While the main function of 2G technology is the transmission of information through voice calls, 3G is all about transferring of information through data such as images and video. With so many different mobile technologies arriving one after another in rapid succession, it would be sometimes confusing to understand the negative and positive differences between them. Today one can make and receive calls from any part of the country.
However, when 3G mobile networks were deployed, they did not immediately offer the same coverage as 2G. This is because 3G technologies operate at a higher frequency than 2G and as such the coverage extended by a 2G tower can be upto 10km whilst a 3G tower can only extend up to 3km. As such a much larger number of 3G towers will be needed to achieve the same 2G coverage. It should be noted that 3G handsets are designed to also work on 2G network as well, to make and receive voice calls but not for high speed data applications.
Therefore, you will have instances that a 3G subscriber can make voice calls at a certain location but not be able to get an Internet connection, which can cause some confusion and disappointment. The same applies for in-building coverage where you may be able to make and receive calls inside a building but not be able to get an Internet connection as the subscriber is too far from the 3G tower. The primary difference between 2G and 3G networks for mobile subscribers is that they get to enjoy faster Internet browsing and data downloading on 3G.
On average, the speed of data transmission on a 2G network is only Kbps, while in 3G networks the downloading speed can go up to 42Mbps or 43, Kbps.
