Symphyl,will take a stab at it.Assuming the 30 miles on the hypotenuse is correct,then the Strat would have to be within the 30 mile range of one of the 4010s on the ground,not all of them.They would be able to backhaul the info to one another till the info is reached by one within the Strats range.
IMO the info being transmitted between strats must be sent at longer distances than the 4010s typical 35 mile wimax range.Also upon further review of your ealier post, think you were correct that the ground networks are not replaceable once the strat arrives.Personally still do not see how i'd communicate from the middle of a desert,or ocean with a strat 13 miles above me and 200 miles to the right,with no 4010s around.
