"It's called Project Skybender, and it aims to deliver 5G internet from
solar drones. Mountain View has reportedly begun experimenting with
millimeter wave-based internet in Virgin Galactic's Gateway to Space
terminal at Spaceport America in New Mexico. Millimeter waves are
believed to be capable of transmitting data 40 times faster than LTE and
could become the technology behind 5G internet. DARPA began working on an internet connection based on it for remote military bases in 2012."
This could work, I suppose. But it sounds like there are a lot of wrinkles to smooth out first.
