Tyche, wind your neck in for a second.
First, of course I'm aware of the AVN/EE contract. IMV that relationship is far more about providing network "resilience" - to use the EE quoted term - than primary 4G network extension. It's pro-tem and/or redundant failover connectivity.
Secondly, please for the love of God work it out. Say Tyche sends a ping over his VSAT rig aimed at a server in London. Up that ping goes to the satellite in orbit (36,000km). Down that ping goes from the satellite in orbit to the groundstation - let's say Goonhilly (another 36,000km, so 72,000km so far). From there that ping heads off over normal infrastructure off to the London-based server, which replies and sends the reply back to Goonhilly.
Off the ping reply goes up to the satellite in orbit (another 36,000km, so 108,000km so far)... and then (yes, you guessed it) back down from the satellite in orbit to Tyche's VSAT rig (yet another 36,000km, so total travelled = 144,000km).
That is exactly where the 500-600ms latency which you acknowledge comes from, FFS. Where pray tell is the fantasy?
But encouragingly where we do agree is that AVN and other sat operators do have a potential market in providing backhaul to 4G MNOs precisely like Millicom/Tigo in markets like Africa...
