Learn about 4G technology on Xiaomi Redmi Note 9
4G describes cellular network technology. It was determined by the ITU (International Telecommunication Union) and used by telecommunications companies. To name a system 4G it should meet some criteria.
The ‘G’ in 4G stands for generation, and 4 means the fourth one, following 3G and preceding 5G. 4G networks should deliver internet speeds much better than 3G, they also present low latency, which is principal for some uses such as gaming services.
The most common protocols specified by ITU as a 4G are HSPA+ and LTE. Xiaomi Redmi Note 9 4G and 4G in most devices today use one or both of them, which makes 4G the fastest most utilized cellular network.
