Introduction to 4G technology on Xiaomi Redmi 9i
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+.
Advantages of 4G on Xiaomi Redmi 9i
4G bypasses the old generation in terms of speed and latency. It has 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, on the other hand, 4G has half of that, meaning 50 ms, which is preferable because 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 standard that gave 4G a boost. It allows users to make improved voice calls and surf the internet while talking on portable. These advantages make Xiaomi Redmi 9i 4G technology a great tool in your pocket.
Get to know 4G bands in your Xiaomi Redmi 9i
4G and other mobile networks use radio waves to transfer data. These waves have different lengths and frequencies. To avoid interference between signals, governments and the ITU regulated which regions use which frequencies for 4G.
Each region has been designated certain frequency intervals termed bands. Band number 7 and band number 28 (as an example) are used at the international level.
What you should know as a consumer is that each carrier provides specific bands according to the area, and different phones support different bands. So you should make sure that your Xiaomi Redmi 9i supports the bands provided by your local cellular operator.
Here are the Xiaomi Redmi 9i 4G supported bands:
1, 3, 5, 8, 40, 41;.
