Keep in mind, the entire Starlink array will only be able to handle like ~1% of global consumer internet traffic. They're only a handful of gbps downlink each. ~10gbps downlink.

But if you remove all streaming/porn/torrent traffic it would be able to handle a lot more of the global traffic.

What's the point of such internet? I can already buy low-cap 4G cheaply.

That's interesting that they say 100% of the components will burn up on reentry— is this an updated design? That wasn't true for the previous batch

Yes, this is apparently an upgraded version: https://spaceflightnow.com/2019/11/10/spacex-readies-upgrade... that has gone from 95% to 100% demisable, and also has Ka band antennas in addition to Ku.

Will this still be true when the versions with inter-satellite laser links are launched next year? I heard that, at least initially, the links may require hardware that will not fully burn up.

I do wonder if that fairing endeavor will come out net positive over the lifetime of Falcon. They paid for a specialized boat to catch the things, and iterated on the boat design several times. Starship is the real reusability project; Falcon is now just holding on to revenue while they get Starship ready to take over the entire launch market (including their own). The fairing is passive, I really wonder if it would…

I've been thinking about this, and it seems doubtful. The fairings are under a million dollars apparently, so they'd have to recover many dozens if not hundreds to pay back the investment into all the catching technologies. It's not clear that they'll ever use that many fairings before switching over entirely to BFR.

Wut? The fairings are $6 million. Highly unlikely they spent even that much to develop a little engine and a boat with a net.

20 Gbps per satellite, according to the FCC filings. Which isn't that great.

So theoretically the more remote a location the faster the starlink will be because it is shared by fewer people. Which is the exact inverse for wired infrastructure.

Except that the more remote your location the further you likely are from the nearest ground station, which means more hops through the satellite network before you get back down to the ground, higher latency, and reduced total throughput of the system.

The system Starlink is trying to beat is BGAN and regional Ku/Ka providers. If you're expecting them to beat the pants off of your terrestrial wired service you're probably going to be disappointed, unless you're on the edge of the range of some old neglected AT&T DSL line or still trapped on dialup. Even then it's almost certainly going to be much more expensive but at least it will have a sizeable speed advantage.

Can't wait to see every Tesla become a wifi hotspot hooked up to Starlink. Traditional ISPs are in trouble if the Starlink latency is really in the sub 100ms due to the LEO distance advantage. Global coverage with decent latency! I wonder if that's why google dipped out on rolling out fiber infrastructure. Physical infrastructure is about to become obsolete as more advancements in wireless tech and satellite internet…

> Can't wait to see every Tesla become a wifi hotspot hooked up to Starlink. The Starlink receiver is the size of a pizza box (and cannot get smaller, since that is the size of the necessary antenna) - and doesn't work while moving. So it's impractical to use on cars. What Tesla probably could do is put a receiver at every Supercharger and broadcast wifi there. It would be especially useful at the more rural location…

With the USAF, SpaceX has demonstrated 610mbps[0] to the cockpit of an aircraft in flight.

Curious about the 'doesn't work while moving' that seems to me to be one of the advantages of a phased array. Since it is software derived aiming I would guess it would excel at adjusting for movement. Do you have details on that I can read on?

People already covered why that's not possible with Starlink, but in-car WiFi is already incredibly cheap and works well.

My Volt included unlimited data for 20$ a month, and it was fast enough for streaming video and worked at times where my phone didn't (presumably because of the better positioned antenna)

If you remove all of that what's the point of even having Internet anymore?

I'd feel about the same as I do when Comcast wants to use my own cable modem as a public wifi hotspot. At this point I'd just like to have a built-in wifi hotspot for my own usage in my car. My Chevy can do this. My fancy high-tech Tesla cannot.

What if you were paid some/all of the profit via micropayments when people used your tesla/modem hotspot?
