FWIW, in my country the historical ISP is pushing for a dedicated network for industrial and hobbyists connected devices. The pipes are already wired.

Can you give more information? From your description, it sounds like "Let's limit possible DDOS targets for hacked things to just factories." , which doesn't strike me as a solution.

I recently did a small talk to some fortune CTOs who have sizable physical operations and logistics. Their heads exploded when I asked what the plan was for the 150,000 little computers they just placed on their LAN DDoSing the operational systems.

Even 4G (LTE) is typically end to end encrypted. Unsure what you are trying to say or if you're just trolling.

Isn't it just mobile station to base station encryption, not true E2E encryption of calls (which would never be allowed)?

Here's a good paper that came out in 2015 about LTE security that's worth a read:

It was put out by NIST (National Institute of Standards and Technology)

Spectra efficiency and even faster data rates are nice but I wonder are carriers going going to upgrade backhaul link and IP core network to allow customers to take full advantage of 5G air interface? This a huge capex spending. I wonder if customers willing to pay even more exorbitant prices for 5G plans for their phone?

With those speeds 5G could be an alternative/replacement for cable/DSL for home internet access. I'm not sure the carriers would be on board with that tough as its its easier to oversubscribe mobile devices than home internet.

No end-to-end encryption though. Oh well, maybe for 6G?

Even 4G (LTE) is typically end to end encrypted. Unsure what you are trying to say or if you're just trolling.

As someone that has written code to pick up the encryption keys out of the Diameter protocol, and used those to decrypt the control plane NAS signaling on the S1 interface, correlated this info with the user plane data between a S-GW and P-GW - no - LTE is not end to end encrypted.

There's encryption between your mobile and a few nodes within the core network of your carrier - inside that network, you can easily break that encryption if you get hold of the keys - and those keys are communicated in plain-text between a couple of the network nodes (on the S6a interface). While those interfaces are supposed to be using IPSec, I've yet to see anyone doing that all the way.

The radio interface, between your device and the cell tower is decently protected though. Unless you're in a country that demands the use of the EEA0 and EIA0 encryption algorithms (a.k.a. no encryption at all).

Though 3/4G already is, it's what many people use instead of wired internet here (Finland) and it's often marketed as such. I rarely get under 25mbps in our clubroom that only has 4G internet access.

These days with 4G i do find that it is not the technology that is the bottleneck. It is the carierers trying to hold on to their business model. I would prefer if we aimed our research on increasing coverage.

The technology is still a bottleneck, but the business model just isn't tightly fitted to the limitations of the bottle neck.

4G cannot viably stream 1080p netflix into the number of homes in America that use it at any given time (unless you use an unrealistic number of cell sites).

Some sort of rationing has to occur otherwise cells would be overrun.

Carriers should bring back free nights and weekends.

5G is for more countries than just the US. Plenty of countries are very happy with the local carriers.

Wow so carriers have really built out their networks in Finland it sounds like. I think this is probably true of all the Nordics no? There are no caps on your 4G? I am curious are you using a mobile router? My experience with these has been that there were data caps attached to them and the plan, as opposed to a 4G unlimited plan on my phone.

I can't speak for Finland, but in Sweden I don't think there are any plans with unlimited data anymore, that weren't grandfathered. There used to be when 3G was the norm, but now that 4G is available pretty much everywhere you'll be capped most likely. My plan for instance is capped at 100gb I believe, for which I pay about 500-600 SEK / month. (This includes all domestic voice and texts too.)
