This is good news for the USA, but it's GREAT news for countries where the government regularly cuts off and controls the Internet for political purposes. If receivers can be as small as a personal laptop, expect a thriving black market in them in places like Iran and Egypt.

Such receivers can also act as backhaul for mesh networks, providing access to un-censored information in times of turmoil and peace alike.

They'll probably just end up turning off service over certain geographic areas.

Why would they do this?

EDIT: Data customers would pay for access on an individual basis. Helicopter-parent countries might cry foul, but what leverage do they have? It's not like they were going to launch things with SpaceX and they can threaten to stop.

Lawsuits, or indirect pressure like limiting Tesla sales.

They could always keep operating anyway, but it's only a matter of time before these governments set up jammers.

Do we have space in orbit for this? This is a lot of satellites and I also don't get how the latency can be so much lower than current satellite ISPs?

Yes, until some of the thousands of small satellites about to be launched (not just by SpaceX) star breaking down and creating space junk that will become a serious problem to the launch of new satellites and spacecraft

It's a cool system. There's a slight disadvantage that the satellite-to-ground link is at 10-15 GHz for users, so it will go down in a heavy rainstorm, and some fraction of the time due to other atmospheric effects. Should be reasonably reliable but far from fiber, and it will be interesting to see what uptime they guarantee. Assuming this all ever actually happens.

This may help explain why Verizon is cutting FiOS prices and increasing speeds: https://arstechnica.com/information-technology/2017/04/veriz...

Gigabit fiber is being rolled out in my area. It is amazing how quickly it is progressing compared to the work of Verizon or Google Fiber. So at least from that one example, there seems to be new players entering cities

Comcast just released Gigabit (over copper, DOCSIS 3.1) for all of Utah. It's only 40Mbit up, but I'm pretty happy with it. I thought it would take a lot longer.

1) Space is huge. This is a little like asking if there's enough space left in earths oceans to float a few thousand pingpong balls.

2) Present internet satellites are all in mostly geostationary orbits that are much further away then the proposed leo's. Realistically the ones we have now introduce a whopping 650ms. This will be a huge improvement.

"SpaceX has also proposed an additional 7,500 satellites operating even closer to the ground, saying that this will boost capacity and reduce latency in heavily populated areas." This should be interesting, depending on how this is regulated on the legal side it could result in the major ISP's updating our infrastructure, of course nothing has stopped them from agreeing to update infrastructure then running off with…

> Not to mention they will probably use legal means to hamstring this if possible. I wonder how this could work. It's not like, e.g., Milwaukee has any legal oversight over LEO.

One possibility is passing laws/regulations about how many sats can be in a orbital plane or single launch, as they will want to launch dozens, if not the full 53 they want to put in a plane, with a single booster to reduce costs.

They could also get some silly RF regulations passed that make it not feasible economically.
