Introduction to 4G technology on Xiaomi Redmi 4 (China)
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 Xiaomi Redmi 4 (China)?
4G outpaces the former generation in terms of speed and latency. It provides 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 provides 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 an enormous 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 use the internet while talking on cellphone. These advantages make Xiaomi Redmi 4 (China) 4G technology a great tool in your pocket.
What are 4G bands? and which bands are available in your Xiaomi Redmi 4 (China)?
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 multiple applications besides 4G (radio broadcasting and Aeronautics as examples), it is vital to decide which frequencies must be used for what use. 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 4 (China), is whether it supports the bands present in your area by your local mobile operator or not. The Xiaomi Redmi 4 (China) 4G supported bands are :
