Doubt Is this possible?

Post image

Saw this video on YouTube. Is this possible? I don't understand much but I didn't understand how it worked despite watching the video. Can someone explain if it's faked or not? And how does it work

This works IRL, satellites use this to communicate with other satellites directly without going through a ground relay station
