NASA and Nokia are putting a 4G network on the moon - CNN

That could give us stuck on Earth a much better shot of astronauts bouncing around on the lunar surface: Buzz Aldrin was a great cameraman, but he didn't have an iPhone.

The 4G network on Earth is supported by giant cell towers with enormous power generators and radios.

But Bell Labs helped create small cell technology that's more limited in range but uses far less power than traditional cell towers and is significantly easier to pack into a rocket ship.

That small cell tech is currently being deployed for 5G networks across the world.
