Ending 3G Service Sparks Fears of an 'Alarmaggedon' (axios.com) 132

AT&T's planned shutdown of its 3G network Tuesday has sparked fears that home security systems, medical alert monitors and a range of other devices will stop working. From a report: Carriers have previously retired networks, but this transition is proving more complicated because the pandemic hindered companies that rely on 3G services from making upgrades. Plus, there are just more devices to manage. AT&T, T-Mobile and Verizon are all planning to shut down their 3G networks this year to support new 5G services. AT&T, which first announced plans to sunset its 3G network in 2019, says less than 1% of its mobile data traffic runs on that network. The company has offered customers free and discounted 4G LTE phones to help them upgrade, totaling about 2 million replacements. What to watch: AT&T says phone coverage will not be affected, but it's not just phones that use the company's 3G network.

    This is exactly what they did for me. I was debating which non "smart" phone to get. During that process they contacted me. I told them what I wanted and they sent it to me, free of charge. Had it activated that weekend at the local store.

    Other than running on KaiOS and its idiosyncrasies, no problems. It's a phone and does what a phone does: make and receive calls.

      I'd have loved to have been offered a KaiOS phone. I had high hopes for FirefoxOS and was glad to see it get a new lease on life.

      The only thing they offered me was this absolutely abysmal AT&T Radiant Core running Android Go. It's unusable trash.

      A lot of these devices are not phones though. They are modems for things like fire alarm panels, security monitoring, even older connected vehicles like some Mercedes Benz models with MB connect. Some older computers have old modems that are embedded systems.

          Those devices are in general illegal to use since they cause interference with other services locally.

      • A lot of these devices are not phones though.

        Cell phone carriers have been pushing the Internet of Things for years. Now they suddenly don't want to support it. Be glad IoT wasn't more widely adopted.

        • Indeed. They even created a whole standard dedicated to supporting IoT. It's called 5G. 3G was always an arse stupid standard to try and deploy a sensor network.

          • And yet it was the state of the art for awhile. The telecoms pushed that standard, they wanted everyone to use it, cellular modems were designed around it. Then the telecoms said "Ha, just kidding! Funny joke, huh?"

            At the very least they could put up some cellular repeaters or such.

            • The telecoms pushed that standard

              Did they? Not sure about your crazy telecoms but while 3G was state of the art telecoms here pushed GPRS for IoT (which made far more sense) while in parallel rolling out, LPWAN, LTE-M, and eventually LoRaWAN and NB-IoT.

              It would be crazy for your local telecoms to "push" 3G as a standard when specifically the 3GPP identified it wasn't sufficient for its use to the point of specifically addressing its deficiency in Release 8, which is incidentally not part of what is being shut down.

            In the process they orphaned a huge number of existing applications, including a large number of cars and alarm systems. They have also convinced me there is no point in ever developing a device to support 5G since they will surely abandon it very soon (LoRa for the win).

            Meanwhile, if I grab the phone off of my kitchen wall and hop into my slightly modified DeLorean, it will work just fine in the 1950s (just slide the switch to pulse dial).

              You still have analog POTS service on copper pairs? In Australia they've shut that down - the only way you'd be using an analog phone is if you have a device that bridges it to an IP-based service (e.g. an AVM FritzBox). Analog POTS did last longer than any mobile phone standard has, though.

                Some parts of the U.S. have seen the old POTS lines de-comissioned, but in that case they typically get a converter box to bridge their house wiring over to digital.

                I know at least one of my neighbors switched to IP phone service with the broadband provider, mostly because his son comes over once every two weeks or so to call his dad and tell him their phone is out again.

          You're using an odd definition of "suddenly" that means "announced four years ago and delayed at least twice."

          Unlike wireline infrastructure where you can always run another cable, wireless spectrum is limited. With that same 20 MHz of spectrum you can for example serve a few tens of thousands of 10-year-old 3G devices with narrowband service or you can repurpose it to serve millions of 4G or 5G devices with broadband service. Which is a better use for people and the economy overall?

        Not sure if the 2G net still is around, some devices do have a fall-back to 2G if 3G isn't available. And 2G may still be available in some areas/countries just because it's a fall-back service.

        Might not work for all carriers and every device.

        And there are likely a large amount of embedded devices out there that suddenly stops to work when 3G is lost and if the 2G fallback is lost then even more devices will be dead.

        And it's as noted elsewhere that it's often alarm devices (like bedside alarms for elderly)

        As someone that had AT&T and an unlocked S8 when it came out, I know a bit about it. At that time AT&T didn't allow, don't know their current stance, non-branded phones to have wifi calling and voLTE. Not sure if/when AT&T may have changed that policy, but I see references to it still being in place in 2019. The S8 was released in 2017. If AT&T has changed the policy it was likely after Samsung stopped supporting the phone.

        Feel free to correct me if I'm wrong, but it sounds like it's AT&T fault your unlocked phone won't work.
        • Perhaps it is AT&T's fault. I've had a heck of a time just getting either entity to acknowledge the absurdity of the situation.

          At least I can take my unlocked Pixel 6 and phone number to a different carrier if I want. Unfortunately AT&T still has the best rural coverage in my area last I checked. But then that was when they had not turned off 3g.

            Yeah, it sucks either way. AT&T's stance on volte/wifi calling was a big part of why I left. That, and I switched to Mint and dropped my bill drastically. At least in my area, rural but near enough to the population centers, the coverage was similar. That, and hills/trees really cause problems regardless of carrier. I think the T-Mobile network has more dead zones, but those are further off the main roads.

        I have an unlocked Galaxy S8 with Telstra branding (works with any SIM card, but shows a Telstra logo on the boot screen), and it's worked with VoLTE since day one. The Australian 4G networks have all required VoLTE since launch. The kind of chaos you're experiencing seems to be a uniquely American problem.

I had a network of about 150 3G modems that I transitioned over to LTE almost 3 years ago when Verizon gave me a shutdown date of like Jan 2020 and that still hasnt happened.

      Eventually you just have to eat the cost and replace that gear.

Either way, AT&T wins.

        So broadly speaking 4G has only been available for a decade, with reasonable options for substantially less.

        This gives a service life for some hardware of maybe 5 years. That's beyond awful for permanently installed things like alarm systems.

        • And 3G has been around for about 20 years with the turnoff date announced with at least 4 years of warning (I got a notice from Verizon in 2018). If you are an alarm company you knew this was coming and your 3G modems are likely over 10 years old and more likely 15. If you were deploying 3G in the past 5 years you were short sighted to say the least and you should have mature 4G devices in your pipeline by now.

            Another thing that lasts 20 years is patents. Carriers shut down service on an air interface about when essential patents on the air interface are set to enter the public domain.

In any case the infratructure manufacturers are no longer interested in keeping production lines for 3G transmitters, the modem companies are also not interested in producting CDMA/GSM radios and the carriers would like to reclaim that spectrum for faster services. No matter how long you keep 3G service online you can't make it any faster.
