Wireless mobile technologies have evolved enormously, One of the main developments is the emergence of 4G technology. It’s a term that you’ve certainly encountered in your daily life, but what is 4G? And is Oppo A31 (2015) 4G enabled? We are going to answer these and other questions related to Oppo A31 (2015) 4G technology in the following article.
is Oppo A31 (2015) 4g eligible?
Yes. 4G is one of the Oppo A31 (2015) embedded attributes.
How do you tell whether the Oppo A31 (2015) is 4G capable or not?
The safest option to check the existence of a 4G network in any phone is to check the official website or packaging.
Another reliable option is turning on mobile data, and checking whether the phone connects to a 4G network or not, you’ll find that out simply by the appearance of a 4G or LTE sign in the notification bar.
Another way is to check the settings: Go to your settings and look for network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone has 4G you will find 4G option or LTE. If you don’t see 4G or LTE, then your smartphone doesn’t have the technology.
How to switch to 4G on Oppo A31 (2015)?
If you need to turn on your Oppo A31 (2015) 4G network, then follow the instructions (it might differ a bit from the settings on your own device):
1- From Home screen, select Apps.
2- From the Apps tab, select Settings.
3- Tap Mobile Networks.
4- Tap Network Mode.
5- Select 4G or LTE option.
Note: If you need to switch off 4G then choose an inferior network type (e.g. 3G) or tap Only 5G if it’s possible.
Introduction to 4G technology on Oppo A31 (2015)
4G is the fourth generation of wireless technologies, it comes just after 3G and before 5G. Although 5G is considered the highest technology existing in the market, 4G is still the fastest most widespread technology.
4G has fast uploading and downloading speeds, exceeding the previous 3G standards, and it also came with lower latency, allowing users to try much more things using their phones, things such as live conferencing.
To be more accurate, 4G is a designation assigned by the International Telecommunication Union (ITU), and it is also a commercial term used by telecommunications companies to express a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for Oppo A31 (2015) 4G to be useful, it should be suitable with the protocols used by the local telecommunications companies.
What are the advantages of 4G on Oppo A31 (2015)?
4G outruns the former generation in terms of speed and latency. It offers 10 times better 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 preferable since latency is a time delay between the sender and the receiver. Although the difference is only 0.05 seconds, it presents a vast advantage in live interactions, like gaming experiences and live broadcasting.
VoLTE is a protocol that gave 4G a boost. It permits users to have better voice calls and browse the internet while speaking on phone. These advantages make Oppo A31 (2015) 4G technology a great tool in your hand.
Get to know 4G bands in the Oppo A31 (2015)
Before talking about 4G bands, you should know what the frequency is. Frequency is the repetition of an event, it is quantified in radio communication by hertz (Hz).
Since radio waves are used for different uses besides 4G (television broadcasting and satellite communication as examples), it is essential to determine which frequencies must be used for what purpose. Otherwise, radio waves will contradict, and it would be a mess.
Governments and ITU designated each range of frequencies (called bands) to certain uses.
What you should consider as a user of Oppo A31 (2015), is whether it supports the bands provided in your area by your local carrier or not. The Oppo A31 (2015) 4G enabled bands are :
38, 39, 40, 41;.
