Don't buy them then? It's not like you can control most IoT today

Hopefully that remains an option. I look at it like Smart TVs today. It's pretty much impossible to buy a TV that is not smart. If IoT takes off this will become the case with many other things imho.

Faraday cage houses will become a thing.

In circumstances where there is such a thing as a "month's worth of data". Which is still a lot of places, but you can get truly unlimited contracts in some places now, for reasonable amounts.

> you can get truly unlimited contracts in some places now This makes it sound like this was not possible before. But e.g. my mobile provider Elisa never did have data caps in the first place, it's been unlimited since GPRS (and no weird tethering limits either).

Probably very country dependent! I've only had that sort of deal for the last 5ish years.

How do you avoid bad actors in these scenarios? Sounds ripe for general havoc, targeting specific people etc

Yeah, I could see someone have button to transmit hard braking on demand for tailgaters.

It’s not a legal right to endanger others so a tailgating protocol isn’t on the face bad. It’d definitely need to be carefully executed though.

Edit-I doubt anyone would be able to make a zero trust network like that incorporate control components. It’d probably be like “I’m going 100 mph with no governor active.” The receiver chooses what to do.

> A fifth of the US population lives outside of big cities. That's not a big fraction, but it's a small fraction of a very big number. Being able to capture that market even for a decade would basically bankroll SpaceX's Mars goal by itself. That's about 25 million households, or about $150 billion gross revenue (not profit) over a decade at the price assumptions you give. If SpaceX’s public estimate of total Mars pr…

Eh, don't underestimate the savings from reuse that's actually practical and not cost-plus. I think SpaceX have demonstrated the economic case for their approach with the F9. And once SpaceX demonstrate they can put cargo on Mars, NASA'll have to get in. Plus people may actually pay to migrate. If you think those numbers are unrealistic, look at SpaceX's posted total costs for their rocket development programs. I thi…

> Plus people may actually pay to migrate.

Sure, but “rich people's vanity may help finance the program” (and NASA will help finance the program, etc.) doesn’t anything to support “satellite internet will finance the program by itself”.

5G doesnt seem like its enabling anything fundamentally new. The talk of any ”killer app” based on having more throughput or on these optimizations always feels like demand generation and slightly inauthentic. Are there any technologies enabled by these techniques that are not possible today?

If you can find old publicity and propaganda from 4G, 3G amd even GSM deployment you will find the same tired set of new capabilities that will magically come true,

5G’s actual advantages will be more prosaic which Ironically will lead to them being more profound. It’s not really clear which they will be though.

Be careful with expectations of "possible" vs. "practical". 5G for IoT devices is a big deal in remote field and some industrial settings where wi-fi is not an option. Two examples for you: I worked on a pilot project with a state government group that wanted remote monitoring of water levels in wetlands and ponds spread across a few hundred square miles of mostly-rural area. wi-fi obviously wasn't an option and gett…

Seems to me the 'lots of vehicles' communication can be solved using a mesh network with the vehicles as nodes. The trend is in that direction already and can serve a pre-delivery function.

Last mile for fixed rural wireless broadband seems like the obvious one. Today, this is generally done with either LTE or various proprietary things (or if you’re particularly unlucky, satellite). 5G should allow for greater total bandwidth, reducing the impact of contention. And on the other side, it should be helpful for very dense urban usage. Try using LTE in a large city’s central train station at a busy time an…

There’s a huge push at the US federal level to get fiber to the home in rural areas. 10s of billions in funding. A lot of times it’s run by the electric companies (coops). They already have the right of way, pole access, and customer relationships. There are dozens of utilities pursuing this, haven’t heard of any working with 5g. There was a recent executive order restricting foreign equipment on the grid, and I susp…

Most coops aren't able to make use of the funding due to competing regulations getting in the way. My local coop has been sending us updates every few months on the situation and they're just getting ignored. Their recent emails have taken a more cynical tone that the government was doing more than playing lip service.

Woah, that's an enormous sweeping generalization. I have a friend whose parents live in rural Kansas who to this day can't get more than dialup or satellite, even though they've called up every single semi-local ISP (way more than once) and said they'd be willing to pay for installation. At this point, they have more than $20K saved for the chance that some company says maybe . It's simply way more complicated than y…

No, parent cited _business_ Gigabit. You're talking about retail consumer connectivity. Totally different things. Based on my deep knowledge of connectivity options here in rural Montana parent is correct: there's lit fiber all over the place (certainly to all cell towers) and various telcos will trench up to 5km from any of those pops, for a price. So a business looking to acquire Gigabit connectivity can readily ac…

I shall tell my friend about that. Thank you for the information!

Nope. Your vendors a lying to you. 5g in general will require a lot more power. That's one of the barriers.
