Mardy, terrestrial networks seem just fine for cities and once out of cities, the Globalstar system seems the best method. Admittedly I have costed them, but 21 km high means signals won't go from inside a house with a corrugated iron roof to the satellite. Horizontal signals seem better.
Maybe it makes sense, but not to me at present. Storms, crashes, capital cost, coverage to inside buildings, propagation distance disadvantage to terrestrial, control, technology upgrades.
Anyway, 37 GHz isn't aiming at mobile phones, but maybe at WLL residential Web connections. Also, from experience, rain interrupts satellite connections [at whatever my Starnet service frequency is]. That might be part of the game while the Web is in infancy, but when people are used to ADSL and better, they won't want to go offline when it rains.
