How can satellites have low latency? The current average ping times seem to be around 900ms. Isn't this almost unusable?
SpaceX satellites will have a very low orbit. That’s also why they need so many.
Here's one way I could see this killing Comcast, even in major cities: As a homeowner, you by a small box which lives under the eave of your roof. The box has high-bandwidth, low-latency satellite uplink to SpaceX which gives you your internet. The same box also has a terrestrial wireless repeater which serves the local neighborhood. Internet is available through your "tower" to neighbors and passers-by. You and Spac…
This is monumental - I claim every major advance in communication technology immediately precedes a major progress for society. This will make the 'Internet' truly global and ubiquitous. So excited for the developing world.
I'm from a third world country(Sri Lanka) and we already have really cheap LTE access, the connection I'm using right now(on my phone) gives me something like 1GB/1.5USD at average 4MBPS. What sucks is the speed and reliability, speed always fluctuate and even though most of the island is now covered by 3G, LTE is not a given. It has been improving a lot though because we have relatively good competition between mobi…
Sorry, needed to get that out. I'm a little frustrated here, because I have been in several poor countries (Africa, Thailand, Moldowa) and they've all had a way better internet coverage than Germany.

I'm from a third world country(Germany) and we don't have cheap LTE access. I pay more than 40€/month (about 50 USD) for 4GB of LTE and I got my contract for half of what it would normally cost. The reception is very poor and I barely ever see the LTE popping up on my phone, most times it's just 3G. And that's in the ex-capitol of Germany. If I visit my parents, which live barely a 45 minute drive outside of the city…
I lived in Germany for about 5 years. Half of that the last 300m of connection to my house were over the thinnest legally allowable copper wire. 3.2mbps max speed down on a very very good day (usually sub 2mbps), about a tenth or slightly more up.
My in-laws previous house was semi-detached and the neighbours house have fiber, but theirs didn't. Same actual building but KabelDeutschland wouldn't run an extension just 2 meters to the wall on my in-laws actual house.
And I mean 'won't' not "couldn't". They scoped the cost and agreed to pay for it to be done, even at the overinflated price, and KD actually said they didn't want to do it.

Recurring revenue - launch the satellite constellation once and generate monthly subscription revenue potentially running into billions of dollars a month. Manufacturing limitations & launch pad availability, once they are resolved (along with launcher reuse) will lead to a point where there is not enough demand to fill the launch roster. This internal demand will help them fill it up.
I always hoped ISS resupply and mars transport would work as reoccurring revenue. This is probably a great use if he has extra rockets and launch pad time, but it seems a bit of a side project compared to manned space travel.
I’m curious to what layer SpaceX will allow application developers access to. If there is to be any hope of having cryptographically secure communications using this network, it will be essential that the whole stack is open source. Putting blind faith in SpaceX seems foolish.

satellite (earth station) systems engineer here: I highly doubt that there will be access at anything other than layer 3. The CPE will have a 1000BaseT port on it, when you connect to it, it'll hand out a DHCP v4 and v6 IP address on it. Maybe if you pay an extra $15 per month you can get a single static v4 address. I am very doubtful that it will be possible for an individual end user with a rooftop terminal to get…

Only if wireless would actually work, instead of fading in half after one wall and 10m distance. Also, imagine how crowded the limited 2.4GHz spectrum will become with all additional networks and connections.
