Learn about 4G technology on Xiaomi Redmi K40
4G is the fourth generation of wireless technologies, it comes just after 3G and before 5G. Although 5G is the fastest technology existing in the market, 4G is still the fastest most deployed technology.
4G has fast uploading and downloading speeds, overstepping the previous 3G standards, and it also comes lower latency, allowing users to try much more things using their mobiles, things such as live conferencing.
To be more accurate, 4G is a term named by the International Telecommunication Union (ITU), and it is also a commercial expression used by wireless service providers to exhibit a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for Xiaomi Redmi K40 4G to be useful, it should be correspondent with the protocols used by the local wireless carriers.
What distinguishes 4G on Xiaomi Redmi K40?
4G was implemented to provide a more reliable internet connection on phones, and that’s clearly what it did. 4G technology provides much improved downloading and uploading speeds than 3G.
The average 3G speed is around 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 prominent criterion of 4G, is its low latency. We can simplify latency and say it’s the time needed to transmit data or the delay between the action and the actual execution. Lesser latency means a better user experience. 4G Latency is better than 3G by double. The average 4G latency is 50 ms.
With the assistance of the VoLTE standard, 4G now allows better voice quality in phone calls and gives users the capability to surf the internet while making calls.
All of these advantages combined with the low cost of 4G expanded the use of Xiaomi Redmi K40 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
