Wireless telecommunications has recorded a lot of development in the last few years, changing the way we behave. One of the important developments is the emergence of 4G. So is Oppo A57 (2016) 4G compatible? And what is 4G? we are going to answer this and every question related to Oppo A57 (2016) 4G.
Does Oppo A57 (2016) have 4G?
Yes. The Oppo A57 (2016) supports 4G Network.
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.
How do you tell whether the Oppo A57 (2016) is 4G capable or not?
It is essential to check whether your device is 4G enabled before buying it. There are a variety of methods to do so, The easiest method is to check your phone specifications in your phone package, or in the manual. If you don’t have the package or lost the manual, you can check your phone specifications on the official website of the manufacturer or any other credible website.
The second method is verifying the signal bar. If the Oppo A57 (2016) 4G data is running, you will find a 4G (or LTE) icon at the top of the phone’s screen. Note that the absence of that icon doesn’t mean necessarily that your phone doesn’t support 4G.
Another way is to check the settings: Go to your settings and fetch network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone is 4G capable you will find 4G option or LTE. If you don’t see 4G or LTE, then your smartphone isn’t 4G capable.
How to switch to 4G on Oppo A57 (2016)?
If you intend to turn on your Oppo A57 (2016) 4G network, then follow the instructions (it might vary slightly from the settings on your own device):
1- From Home screen, tap Apps.
2- From the Apps tab, select Settings.
3- Choose Mobile Networks.
4- Select Network Mode.
5- Choose 4G or LTE option.
Note: If you intend to switch off 4G then choose a lower network type (e.g. 3G) or tap Only 5G if it’s possible.
What are 4G bands? and which bands are available in the Oppo A57 (2016)?
Before talking about 4G bands, you should know what is a frequency. Frequency is the repetition of an event, it is quantified in radio communication by hertz (Hz).
Since radio waves are exploited for several applications besides 4G (television broadcasting and satellite communication as examples), it is essential to identify which frequencies must be used for what reason. Otherwise, radio waves will contradict, and it would be a mess.
Governments and ITU allocated each range of frequencies (called bands) to certain uses.
What you should consider as a user of Oppo A57 (2016), is whether it supports the bands present in your area by your local mobile operator or not. The Oppo A57 (2016) 4G enabled bands are :
1, 3, 5, 7, 8, 20, 28, 38, 39, 40, 41;.
