I don't think that Satellites will factor much into the 5G situation. I am not even that sure that satellites do much really since 99% of all internet traffic is through under ocean cable.

I really think 5G will be extremely localized, the frequency is too short to be transmitted over large distances and since geo-sycronistic satellites tend to be at 22000 miles up in the sky, it may be impossible to transmit any form of internet considering the distances. I got to tell you the truth, I am suprised they work at all!
Have you considered the Bitcoin satellite network and our ability to put up working satellites that are smaller than the size of a fist? I am not sure how it would work, but everything seems to be pointing to a leap in technological application.
Wow! That sounds cool! A private network off grid. I like it!
