NASA has started a project called 2020 tipping points. The purpose is to develop various technologies on the moon. We get to hear a lot of interesting things about this.
So when experimenting like this they have to take the HD video call. They have to do HD video streaming. And they also have to control the rovers and other equipment on the lunar surface. So they need to use this 4g network for this.
In addition to this 4G network project, a large number of other projects have been funded in this manner.
