The International Telecommunication Union (ITU) has agreed on a preliminary definition for 5G standard. Recently a conference was held from June 10th to 18th where the speed more than 20Gbps more than was attributed to 5G.
so if a mobile network should provide a data speed at up to 20Gbps, it would be termed as 5G. The current 4G LTE mobile networks operate up to the speeds of 1Gbps which is about 20 times slower than the 4G networks.
With 5G, the next-gen 4K and 8K online video playback will be more viable and this could also be used to cater millions of IoT devices inside a large are together.
The ITU expects the commercial 5G to be used from the year 2020 after its international spectrum distribution in 2019 and it is expected to be showcased at the 2018 Pyeongchang Winter Olympic Games.
