Internet on mobiles has witnessed a lot of changes, and different wireless technology generations, one of them is 4G technology. So what is 4G? Is Oppo R15x 4G enabled? Let’s have a deep dive into the subject, and know everything related to Oppo R15x 4G technology.
is Oppo R15x 4g eligible?
Yes. The Oppo R15x is one of the 4G supporting phones.
How do you tell whether the Oppo R15x is 4G capable or not?
It’s not a big deal to find out whether your mobile phone is 4G enabled, but it’s still essential to know how to do it. Because you don’t want to be left over with a device lacking an essential technology nowadays.
You can check the information directly by googling the phone name or model number, and checking on the official site of the manufacturer or any other credible website. If you are a classic person, you can check the user guide or the phone box.
Another easy method is checking the indication bar while the mobile data is on, if the Oppo R15x 4G data is on use, then you will see a 4G or LTE sign there. If it’s not mentioned then you should consider another method.
Another way is to check the settings: Go to your settings and search for network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone is 4G enabled you will find 4G option or LTE. If you don’t see 4G or LTE, then your smartphone doesn’t support the technology.
How to switch to 4G on Oppo R15x?
If you want to turn on your Oppo R15x 4G network, then follow the instructions (it might differ a bit from the settings on your own device):
1- From Home screen, choose Apps.
2- From the Apps tab, select Settings.
3- Select Mobile Networks.
4- Tap Network Mode.
5- Choose 4G or LTE option.
Note: If you would like to turn off 4G then choose a lower network type (e.g. 3G) or tap Only 5G if it’s possible.
Definition of 4G on Oppo R15x
The International Telecommunication Union (ITU) is the entity that defined 4G in the first place, 4G is the fourth generation of wireless technologies. It comes just after 3G and preceding 5G.
4G has very high internet uploading/downloading speeds, ten times more than 3G, Which is enormous. It also has 50ms latency, much less than 3G.
4G is not just one technology, but a set of technologies compatible with ITU specifications. It includes LTE, LTE+, and HSPA+.
What are the advantages of 4G on Oppo R15x?
4G was established to deliver a more reliable internet connection on mobiles, and that’s truly what it did. 4G technology presents much stronger downloading and uploading speeds than 3G.
The average 3G speed ranges from 1.5 to 9 Mbit/s, while the average 4G internet speed is between 15 to 90 Mbit/s, it can achieve as high as 900 Mbit/s.
Another significant criterion of 4G, is its low latency. We can present latency as the time needed to transmit data or the delay between the action and the actual execution. Low latency means a better user experience. 4G has 100% better latency than 3G. The average 4G latency is 50 ms.
With the aid of the VoLTE standard, 4G now allows better voice quality in phone calls and gives users the ability to surf the internet while making calls.
All of these advantages combined with the low cost of 4G extended the use of Oppo R15x 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
Get to know 4G bands in your Oppo R15x
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 used for different applications besides 4G (radio 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 specific uses.
What you should consider as a user of Oppo R15x, is whether it supports the bands provided in your area by your local cellular operator or not. The Oppo R15x 4G enabled bands are :
1, 3, 4, 5, 8, 34, 38, 39, 40, 41;.
