Re: I'm sorry, where's the difference ?
I think the plane use case has the planes not needing to talk to each other with low latency whereas 5G devices do. The planes' data is mostly just telemetry that doesn't need constantly adapting real time networks to ride on. Most of it can be stored on board and exfiltrated in bulk later.
I suppose you could give the planes an autonomous 5G style networking capability, somehow have point to point comms between all the planes currently over, say, the Atlantic. But why? Also, how?
