Mobile operators to shut down 3G networks in 2022

Wed Aug 12, 2020 7:34 am

It's deja-vu all over again: we will have the same problem we did with CarWings/EV Connect vis-a-vis 3G we did with 2G. A couple of things come to mind:
1) Does anyone know if the chip set on the (replacement/upgrade) TCU modems supports LTE (4G) as well as 3G?
2) Has anyone spoken to Nissan about the prospects of another modem upgrade cycle?

I didn't anticipate that a 3G network shut-down would so closely follow the 2G network shut-down, but spectrum is scarce and 5G is on the way. At least we've been through this once before (although it wasn't pretty), but I know I don't want to lose telematics capability in my Leaf. A key to the magnitude of the problem will be knowing whether the current 3G chip set also supports LTE, which allows for the possibility of a firmware as opposed to a hardware update.

Almost certainly not.

No offense...but that doesn't sound very definitive.
If you can identify the chip set (manufacturer/number), then I would believe you. The fact is, I am not aware of any (newer) 3G chip sets that don't support LTE...but that doesn't mean Nissan used one of those.

"Will the new TCU hardware work with the 4G network?
No. The new TCU hardware will be designed to connect to the current AT&T 3G cellular network." and

"Why is Nissan using 3G technology rather than 4G?
Nissan has studied how to integrate newer technology into your vehicle and developed solutions aimed at delivering a hardware update option with the least inconvenience to customers. The new TCU hardware will be designed to connect to AT&T's 3G cellular network. Nissan does not control availability of any cellular network and cellular network may not be available in all areas and/or available at all times."

Who knows if their chipset actually doesn't support it 4G or LTE or it's buggy or if they just aren't using the capability right now?

https://www.att.com/support/article/wireless/KM1324171/ says "One change we’re making is phasing out our 3G network by February 2022. Once we do, 3G devices and 4G wireless devices that don’t support HD Voice will no longer work on our network."

'19 Bolt Premier
'13 Leaf SV w/premium (former)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Well, that sucks; thanks for digging up the Nissan FAQ. I knew about the AT&T stuff...which is really what led me to create this thread.
Guess we will have to do the "TCU upgrade dance" again...and sooner than I thought.

New owner of a 2013 so what does this dance involve? What will be affected if I do nothing? Would I just be able to tether to my phone? thanks

If you use the app to preheat your car, check on charging or look at statistics that would no longer work.

What I don't know and should probably start looking into is if all LEAFs including the 2019 and 2020 only connect to 3g. Not sure how many of us will have to do the upgrade dance.

Maybe I'm cynical, but I highly doubt that Nissan will offer TCU upgrades again for $200 for older model years. It wouldn't surprise me if they offered TCU upgrades on 2018 MY and newer only.

That's why we need to get the facts (however/whoever may have them).
Telematics is a big part of this car (and really all EVs), and the only way to maintain the functionality is for Nissan to provide a 4G upgrade path for the TCU.

I'm probably in the minority, but I just don't care about it anymore. I tried getting the $200 co-pay TCU upgrade, on my US LEAF in Canada, and Nissan blocked that.

I found CarWings/NissanConnect to be buggy and more trouble than it's worth anyways.
