Does it work at 45000'? Seems ideal to have one comm system for low and high altitudes, but at least there should be at most two and no gap in coverage.

I would think so because analog TV over the air was able to travel more then 9 miles, but I don't think that toy drones can go that high, but that will probably change...

Analog TV transmitters were using serious wattage, and it was only transmitting. Wifi will have a lot less transmission wattage and it has to have a lot or reception sensitivity and hundreds maybe thousands of clients. So it's an interesting problem.
