I’ve done this as a project to go from 3G to LTE for a network of a few hundred devices.
3G and LTE (4G) used almost identical AT commands. The motherboards were build so the modems were swappable. It wasn’t too bad. I’m told the field techs had to drive 5 hours across the Australian outback to access some of them.
After rolling out 3g router fail over for pokies, lotto, wagering in Oz I’m sure the money they saved from no longer having any downtime can pay for 4G, 5g, and starlink redundancy.
5 hours of driving across Oz? Wouldn’t even make Carnarvon Gorge much less Mount Isa.
I work on the national electrical grid and there are a bunch of remote sensors in all of the substations. Some of them are what essentially amount to remotely controlled circuit breakers. I think they trip automatically if they lose connection because they assume something bad has happened. So that’ll be fun.
I work on the software side of things I’m not an electrical engineer so I have no idea if they’re actually changing them over yet but they’re still thousands of them on the network at the moment.
I work for the grid too and we also have these. Usually only for bigger substations to transmit measurements and switching states, maybe a bit of telemetry like a tripped fuse.
I hope for dear god that you are remembering wrong and none of them trigger when loosing connection. Whoever thought of that should be immediately fired.
A loss of connection from a single device should never trip a circuit breaker (no idea how the bigger equivalent is called in english), especially if its connected wireless.
The software that controls them is absolutely terrible so I wouldn’t be surprised if that is how they work.
But thinking about it it does seem really stupid for no reason so maybe what it is is the concern that if they do trip after 2G is turned off there’s no way for us to know that.
I was wondering how this would affect car manufacturers and their TCU’s or what have you. Curious to know if cars will be bricked when this is obsolete and they turn off 2G and 3G.
My 2013 Focus Sync 2 software that does system checks shit down like 6 years ago and I periodically get a message that I need to do a diagnostic check and send it in to Ford, but then it errors out.
Is it one of the ones where you can update the software from a USB stick and software off the internet or does it have to do with looking for a software update then timing out because the network isn’t there?
I was wondering my previous question because I know Mozilla just put out a report on how if you own a newer car your automaker is tracking you via the modems built into the cars.
It wants to use my phone to make a call and transmit the data like an old school modem. There’s not built in modem in the car as far as I can tell. It’s a 2013 Focus Titanium.

Beautiful country to drive across tho.
One of those places was Mt. Isa. It was equipment for mining.

It’s annoying as fuck.

It is actually dumber than that.

And it can’t because
new phones don’t use 3G?cell providers shut down 3G services in 2022?No, because whatever back end service ford used, ford shut down.
