Wireless mobile technologies have evolved enormously, One of the main developments is the rise of 4G technology. It’s a word that you’ve certainly encountered in your daily life, but what is 4G? And is Xiaomi Redmi Note 9S 4G capable? We are going to answer these and other questions related to Xiaomi Redmi Note 9S 4G technology in the following article.
Does Xiaomi Redmi Note 9S have 4G?
Yes. The Xiaomi Redmi Note 9S has all the conditions to support 4G networks.
How can I know whether the Xiaomi Redmi Note 9S is able to use 4G or not?
Nowadays, it is unavoidable to get a 4G-enabled device, because most internet users require a good internet connection. To know whether the phone is 4G enabled you can use multiple methods.
An easy method when you have the device in your hand is just turning on the cellular data, if the Xiaomi Redmi Note 9S 4G data is on, then you will notice a sign at the top of the display, in the status bar. It might be 4G, 4G+, LTE, or LTE+ according to your carrier.
The absence of that sign means that you are not using 4G at that particular moment, and it doesn’t signify always that your device doesn’t support 4G. And that takes us to the second option.
Check your phone specifications on the manual, or in the device package. If you don’t have any of them you can still check that on the official site (or any other trustworthy website) using the device name or model number.
Another way is to check the settings: Go to your settings and find 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 either of them, then your smartphone doesn’t have the technology.
How to switch to 4G on Xiaomi Redmi Note 9S?
If you need to enable your Xiaomi Redmi Note 9S 4G network, then follow the instructions (it might change slightly from the settings on your own device):
1- From Home screen, select Apps.
2- From the Apps tab, choose Settings.
3- Select SIM cards & Mobile Networks.
4- Select the sim card you want to manage (the one used for data if your device is dual sim).
5- Tap Preferred network type.
6- Choose 4G or LTE.
Note: If you intend to switch off 4G then choose an inferior network type (such as 3G) or tap Only 5G if it’s possible.
Get to know what is 4G on Xiaomi Redmi Note 9S
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 and 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 latency limits are 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+.
Feature of 4G technology on Xiaomi Redmi Note 9S
4G was developed to offer a more reliable internet connection on mobiles, and that’s exactly what it did. 4G technology offers much enhanced downloading and uploading speeds than 3G.
The average 3G speed ranges from 1.5 to 9 Mbit/s, while the average 4G internet speed ranges between 15 to 90 Mbit/s, it can reach as high as 900 Mbit/s.
Another significant criterion of 4G, is its low latency. We can present latency as the time needed to send data or the delay between the action and the actual response. Lower latency means a better user experience. 4G has 100% better latency than 3G. The average 4G latency is 50 ms.
With the help of the VoLTE standard, 4G now presents 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 widened the use of Xiaomi Redmi Note 9S 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
Get to know 4G bands in the Xiaomi Redmi Note 9S
Before talking about 4G bands, you should know 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 different applications besides 4G (radio broadcasting and Aeronautics as examples), it is necessary 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 Xiaomi Redmi Note 9S, is whether it supports the bands provided in your area by your local mobile provider or not. The Xiaomi Redmi Note 9S 4G supported bands are :
1, 2, 3, 4, 5, 7, 8, 20, 28, 38, 40;.
