On top of that you have the licensing which is going on, so if one of these systems get put into place they will most likely dominate the spectrum so that the others, if deployed, wouldn't even be allowed to transmit. Good answer by the way. I can second that what datenwolf said is pretty darn accurate, but doesn't account for a lot of the inteference that happens to reduce usability of the specturm. You also get into beam widths so and antenna. So if you have 700 satellites up in the air given full spectrum that means they'd have a fixed limit of 10TBit/s. That can be divided between their users (but it won't be anything close to 10TBit/s). So this will really be a factor of how big their beams are, how many people are within their beams, and how much frequency they can legally use. While this is really cool and possible, I doubt this will open up a whole new internet in it's first pass. There is also the issue with, how are they going to get the signal to it's destination? They can't beam it all the way around the world for you, and from what I understand at least OneWeb isn't going to communicate from satellite to satellite. So they'll have to have a ton of ground stations to receive your link and then send it over fiber, or transmit up to GEO, then down again. OR they'll have to hop up and down between nodes to it's destination, in a similar fashion to TOR. I don't know how they plan to solve this or if SpaceX has a better solution.
