I've seriously considered getting a roll and building a cage.

There's also emf paint that one could use.

On a 70" 4K TV a pixel is about 0.4 mm x 0.4 mm. If the mesh were close to the screen I think about 30% of the pixels would have wire in front of them. Of those 30%, 1/6 would both a horizontal and a vertical wire in front (let's not go crazy and talk about orienting the mesh diagonally or anything like that), and 5/6 would only have one wire in front of them. So that's 70% of pixels not interfered with, 25% having one wire in front of them, and 5% having two wires.

The 25% with one wire crossing would have about 20% of the pixel occluded by the wire. The 5% with two wires crossing them would have about 36% occluded.

My guess is that the screen could be seen pretty well through that.

Works pretty well for MR at 3T (which is actually more like 2.89T) though - 125Mhz ish.

Then of course there’s a lack of 5G. I certainly don’t have any where I live. Just about have 1 bar of 4g near the window.

WiFi/Cellular convergence as a concept also doesn't seem like the most unlikely future.

I've seen others in this thread argue embedded cellular isnt worth the cost, but this misses the critical point - if it costs almost nothing (we are close to this point already) and is already built into every off the shelf SoC, of course manufacturers will use it. We are talking pennies per unit at scale here in future.

The auto industry has already done this - Ford for example have embedded cellular analytics you can't turn off (or at least its non-obvious to me as an owner) on every single new Ford and has done so for several years now, and you don't pay a penny as the end user, even on their most basic entry level cars.

Same goes for any other appliance that radiates RF signals (IoT, etc.).

If cell access is essential, what happens in a place without cell access, much of Alaska perhaps?

I hate to think of all the lawsuits resulting from drivers who drive into locations where cells are out of range and get stranded.

Similarly, what happens when the cell phone system breaks down? And does that mean I can't buy a car if I live in an area with intermittent, weak or no cell or internet service? Hate to think what the manufacturer's sales department would think of that.

On the matter of reverse engineering, it seems to me we're just on the cusp of that. Hackers as still getting organized and aftermarket manufacturers have still to tool up for complete computer replacement kits. Reckon we're only at the very beginning of whole new industry.

Oh, I nearly forgot, the Right to Repair movement has only just begun to get organized. If manufacturers try to stop us altering something we've paid goid money for then they'll be in for a long political fight.

So they'll add a $50 LTE/5G modem to the BOM just to save the trouble of entering a password using arrow keys, a process that takes maybe 2-3 minutes?

I do this on old smartphones that I have no intention of ever using as a phone again (say for testing APS etc.). It's dead easy, a razor blade through the circuit board tracks that connect to the antenna(s) and it's all over—no phone, with or without SIM (i.e.: no emergency service) and no WiFi or Bluetooth.

Very simple really.

This coffee machine is equipped with M2M (Machine to Machine) techology which may be activated in due time with your agreement. Thanks to a SIM card already integrated in the machine, such network connections will offer new services (subject to further terms and conditions) to its customers and improve the after sales process by automatically communicating machine troubleshooting / diagnostics to our Customer Relationship Centre (depending on country requirements and specificities).

And if coffee pods don't come with always-online DRM yet, I'm honestly surprised at Nespresso's lack of dedication to this dystopia.

If so, then there would be hell to pay the first time if happened. If it works sans connection, then do what I've said elsewwhere and that's to cut or short out the antenna lead.

Removing the SIM may be deemed provocative by the manufacturer, if there's no signal reception then that's a different matter (the user can't be blamed).

I wonder if I can use it for mobile data.

All over, done permanently. Never another internet connection.

There'd be hell to pay if they ever did that. Moreover, it'd be impossible to keep the fact quiet if deployed at any reasonable scale.

A much bigger looming threat is the possible closure of terrestrial Free-to-Air TV broadcasting (it was an early agenda item to be discussed at the 2028 WARC/WRC (World Administrative Radio Conference) but was dropped early on.

That it ever got there in the first instance is a very big worry, it shows that people in high places have been or are considering such a move).
