Be careful buying what Elon says.

Hyperloop, robo taxis, hell Twitter.

How about that cybertruck.

He says a lot of bullshit, don't assume anything from him.

It’s easy to distinguish. But starlink is happening.

Okay. But you are acting like it's going to change everything...

It's not really... It can't compete with Fiber, Cable, or 5G

It's good for rural areas.

But again tesla almost bankrupt needed government bailout, space x is basically backed by the government, I don't see the government backing up this project... And it may not be profitable enough to survive long term let alone change the industry

I don’t think 5G will be as pervasive as advertised. If starlink continues to prove reliable I would possibly switch as my single broadband carrier where I leave is unreliable for years. Down for hours at least once a week. They don’t care, no other provider serves the neighborhood.

Rural areas will definitely make a difference, as would cell carriers starting to use the service now.

They had satellite internet for decades. It's not a new service.

5g and onward is coming.

This is true...Satellite Internet has been available for decades... ViaSat, Wild Blue Yonder, Hughes Net... All Geosynchronous, very, very slow... no support for VPN with extremely high latency (more than 22,000 miles up). Not suitable for voice calls, video services (movies, video conferences, etc.) or gaming.

Starlink (and Amazon's Project Kuiper, and OneWeb) is significantly different. LEO satellites have very low (almost fiber) latency. And the bandwidth is far greater (20 Gbps for v1 satellite with 80 Gbps for v2 satellites). Now, that bandwidth is shared by everyone in that same satellite spot beam, the more spot beams (and there are multiple per satellite), the smaller each beam is (each with 20 or 80 Gbps), the fewer people using that beam's bandwidth, the more bandwidth every person has... and the more satellites, the more spot beams. That's why the number of satellites matters. Via Sat and others have one or two satellites covering the entirety of North America... they have a few spot beams per satellite. And while they do have significant bandwidth (not as much as Starlink, I believe) it's shared among LOTS of people.

FULL DISCLOSURE... I bought my parents Starlink (so much better in every way compared to the local DSL available in their small Central Oregon town) and I have Starlink deployed at a farm in Hillsboro Oregon. Again, far better than any other option I had.

5G

As a Network Engineer, I was part of a small team looking at 5G vs. alternatives for connectivity to remote substations and communication sites (and as backup access for our generation fleet).

Two problems with 5G (I mean besides the hype). First, coverage isn't increasing... right now it will have, someday, the same foot print as 4G LTE. And right now its not even close to the 4G foot print. But there are SO MANY places where you can't get 4G or where the signal is so weak the service is spotty. Second... the hype was around speeds... up to 1 Gbps (sometimes faster). Sure... using millimeter wavelengths. But using that very high frequency spectrum means REALLY short distances (like you can't even cover a medium size stadium... Verizon tried, had to use multiple base stations to cover a stadium...https://www.5gworldpro.com/blog/2019/09/21/128-verizon-s-5g-network-can-t-cover-an-entire-nfl-stadium/ ). So carriers are scrambling to deploy mid-band frequencies... That's good but its only 2 to maybe 3 times the throughput (we're talking 60 Mbps to maybe 120 Mbps in the vast majority of cases). Nice improvement, no doubt, but hardly revolutionary.

And as a fixed wireless home Internet service... well, the reviews are very spotty. Maybe good if its the only thing you can get.

Another minor issue is the 5G standards aren't complete yet. One advantage 5G is supposed to have is support for NB-IoT (Narrow Band - Internet of Things). That standard is still in development.

And while they say they're friends.. WiFi and 5G are more like frienemies. Nokia, Ericsson, and other 5G providers are trying to convince industrial equipment manufacturers to add 5G transceivers to their equipment, saying its better than Wifi... and John Deere is deploying 5G in their factories. But upcoming WiFi 7 erases most of the advantages 5G has in an industrial setting (fast setup, support for hundreds or thousands of devices, multiple NB-IoT profiles, and the like). Not sure 5G will be very competitive in the industrial setting.

And what about 6G? Right now, the white papers and research papers make it sound like its a local only network... almost a desktop area network (DAN??). Very fast terahertz speeds but at a distance of only a few feet. Connecting monitors, MFPs, Webcams, etc. The protocols I've seen under development seem to focus on things like device connectivity. Though we're pretty early in the discussions.

It's basically worldwide accessible high speed internet.. look I dislike the guy as much as you, but the engineers he's hired have developed this and its a pretty good concept. Once he has enough satellites up he's going to probably become exponentially richer than he already is.

I get that, but again you can't trust this guy.

None of this is new tech, there is a reason other companies like Comcast hasn't already done it.

It isn't new tech, but he's the only one doing it on the scale he is.

Well most companies probably won't get the free money like he does. He is already asking the US gov to pay for starlink in Ukraine
