The Japanese provider NTT Docomo expects its 5g network, the successor of 4g, by 2020, will be taken into use. The new network would be a hundred times as fast as 4g and a thousand times the capacity of the current network.
This keeps the Japanese provider on the things forward, because for the moment it is 5g, not even a standard. Now 4g worldwide is going to be used, look at companies in the industry to what 5g should look like, and what it should be able to; work on 4g began more than ten years ago. Moreover, it is still the question of how feasible the claims of the Japanese provider turn out to be; for 4g was previously reported that the direction of 1Gbit/s would go, but current subscriptions in the Netherlands have a maximum speed of 50Mbit/s.
The 5g network also has, according to NTT Docomo thousand times as much capacity as the current network, something carriers desperately need to have streaming services as Spotify and Netflix, more and more mobile are used.
