Cellular technologies have upgraded enormously, One of the main developments is the emergence of 4G technology. It’s a term that you’ve certainly faced in your daily life, but what is 4G? And is Oppo A91 4G capable? We are going to answer these and other questions related to Oppo A91 4G technology in the following article.
Does Oppo A91 have 4G?
Yes. The Oppo A91 is 4G enabled
What is 4G on Oppo A91?
4G is the fourth generation of mobile telecommunication. It was first released in 2009 in South Korea, and it was deployed after that all around the world until it became the fastest most used network in mobiles.
The provider of 4G network specifications is the International Telecommunication Union (ITU), it has also identified 5G, and 3G specifications before that. The ITU specifies what internet speeds and what are latency limits acceptable to call a network protocol a 4G.
Many protocols passed the test and qualified as 4G, the most important are LTE, LTE+, and HSPA+.
Advantages of 4G on Oppo A91
4G bypasses the past generation in terms of speed and latency. It provides 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 provides a 100 ms latency, on the other hand, 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 translates to an enormous advantage in live interactions, such as gaming experiences and live broadcasting.
VoLTE is a standard that gave 4G a boost. It permits users to have improved voice calls and surf the internet while speaking on portable. These advantages make Oppo A91 4G technology a great tool in your hand.
How can I know whether the Oppo A91 is able to use 4G or not?
It is essential to check whether your device is 4G enabled before buying it. There are numerous methods to do so, The easiest method is to verify your phone specifications in your phone package, or in the manual. If you don’t have the package or lost the manual, you can see your phone specifications on the official website of the manufacturer or any other dependable website.
The second method is verifying the status bar. If the Oppo A91 4G data is running, you will notice a 4G (or LTE) symbol at the top of the phone’s screen. Note that the absence of that symbol doesn’t mean necessarily that your phone doesn’t support 4G.
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 supports 4G you will find 4G option or LTE. If you don’t see 4G or LTE, then your smartphone doesn’t have the standard.
How to switch to 4G on Oppo A91?
If you need to enable your Oppo A91 4G network, then follow the instructions (it might differ slightly from the settings on your own device):
1- From Home screen, tap Apps.
2- From the Apps tab, choose Settings.
3- Tap Mobile Networks.
4- Select Network Mode.
5- Choose 4G or LTE option.
Note: If you would like to switch off 4G then choose a lower network type (3G for example) or tap Only 5G if it’s possible.
What are 4G bands? and which bands are supported on your Oppo A91?
Before talking about 4G bands, you should find out what is a frequency. Frequency is the repetition of an event, it is measured in radio communication by hertz (Hz).
Since radio waves are used for several applications besides 4G (radio broadcasting and Aeronautics as examples), it is vital to identify which frequencies must be used for what use. Otherwise, radio waves will contradict, and it would be a mess.
Governments and ITU designated each range of frequencies (called bands) to specific uses.
What you should consider as a user of Oppo A91, is whether it supports the bands offered in your area by your local cellular provider or not. The Oppo A91 4G supported bands are :
1, 3, 5, 7, 8, 20, 28, 38, 40, 41 – International;1, 3, 5, 7, 8, 38, 40, 41;1, 3, 5, 8, 38, 40, 41 – Southeast Asia;1, 3, 4, 5, 8, 34, 38, 39, 40, 41 – China;.
