Definition of 4G on Oppo A57 (2016)

It is the term used to describe the fourth generation of cellular communication technology. It was identified in 2008 by the International Telecommunication Union (ITU), an agency that specifies the specs of the 4G technology, and previous technologies such as 2G and 3G. 4G now is the main wireless technology used by most mobile phones in the world.

4G comes with speeds faster than its ancestor 3G, thus its release expanded the use of mobile phones. Presently, phone users can do almost the same activities that were only possible on computers before the emergence of 4G.

The most famous technology labeled 4G is LTE and the technologies developed from it (e.g. LTE-A). Usually, people confuse the two terms. For Oppo A57 (2016) 4G to be useful, it should be correspondent to the protocols used by the local wireless service providers.

Advantages of 4G on Oppo A57 (2016)

4G bypasses the former generation in terms of speed and latency. It offers 10 times higher downloading and uploading internet speeds. The average 3G speed is around 5 Mbit/s, and the average 4G speed is about 50 Mbit/s.

In terms of latency, 3G grants a 100 ms latency, while 4G has half of that, meaning 50 ms, which is better because latency is a time delay between the sender and the receiver. Although the difference is only 0.05 seconds, it presents an enormous advantage in live interactions, like gaming experiences and live broadcasting.

VoLTE is a protocol that gave 4G a boost. It allows users to make better voice calls and surf the internet while talking on phone. These advantages make Oppo A57 (2016) 4G technology a great tool in your pocket.
