Friend of a friend works the satellite trucks for onsite broadcasting at sports events. He told me once that he phones the satellite operators and they coordinate to make sure the beams are aligned as tightly as possible to reduce the power loading on the satellite. I’m guessing there’s probably a similar constraint here — I don’t think (pure conjecture) it’s feasible to have a tonne of iPhones (and let’s be honest, they’re everywhere) hanging off satellites.
