I believe there are problems with maintaining a High Altitude Platform in position above 25 km.
Current research is based on platforms between 17 and 22 km high. At that height they could provide coverage over a radius of up to 500 km.
In the UK we have the drawback that aeronautical amateur radio systems are not permitted by our regulator.
