Re: Mobile operators to shut down 3G networks in 2022

Mon Apr 19, 2021 9:10 am

Did a little poking around and it appears that Subaru went to 4G LTE in ~2016 with Sirius XM Connected Vehicle Services and AT&T. Pretty disappointing that Nissan switched to 3G when other automakers were installing LTE. Especially because LTE was well-established by then and 3G was on the wane.

My car will be disconnected before it's 5 years old. I'm not hugely reliant on telematics, though it was one of the reasons we bought an SV over the S. I get that they can't support new cell technologies indefinitely, but leaving us with no upgrade path after a few years is lousy. I'd be willing to pay a few hundred bucks for an upgrade.

This is awesome! Thank you for taking the time to do this testing, and I'm envious of the equipment you have. :D

Thanks. I just bought a new 2020 and was wondering about that. I have been unsuccessful in determining what radio I have. I still haven't found anything 100% definitive. The Connect manual suggests 4G and your experiment reinforces that notion but no-one can say with absolute certainty.
Can't say I agree, I think knightmb's test is about as definitive an answer as you'll get, besides Nissan themselves confirming it.

It's a little fuzzy, but this photo of the TCU from a 2018 Nissan Leaf shows 4G at the bottom of the label, next to "Model Name"

So, that would seem to confirm that any 2018 or newer LEAF with a telematics system is 4G compatible

Using the photo and the FCC-ID, I was about to look it up in the FCC database.

V6V 3A4 N7NAR7552 Original Equipment 06/15/2015 824 849
V6V 3A4 N7NAR7552 Original Equipment 06/15/2015 1710 1755
V6V 3A4 N7NAR7552 Original Equipment 06/15/2015 1850 1910
V6V 3A4 N7NAR7552 Original Equipment 06/15/2015 2500 2570

824 MHz to 849 MHz - 3G Service
1710 MHz to 1755 MHz - 4G Service
1850 MHz to 1910 MHz - 3G Service
2500 MHz to 2570 MHz - 4G Service

These units support both 3G and 4G service. I actually never checked it for the 3G frequency since I was only interested in the 4G working service, so it would appear this radio can support both, neat!

I just can't believe Nissan was installing 3G modem upgrades (instead of 4G) for Gen1 Leafs while they were selling 4G modems in the Gen2 :evil: I'm starting to get worried that we can't get any info on (additional) modem upgrades for the Gen1.

Interesting stuff! It appears that a few part numbers were used from late 2017 – mid 2018 for the Gen2 cars. Unless they all have 4G capability, it may not be possible to make a blanket statement about MY18. It also looks like the 62 kWh Plus cars got a different part from the base 40 kWh car, and all of the earlier TCUs were superseded to a newer part number.

It will take a while, I can probably find the FCC ID for those also and relay back what they support via the FCC database. Unless someone has a nice picture of the FCC ID from all of those handy to post here.... ;)

It was pretty quick to do a Google image search for the part numbers. They all say 4G on the label, whereas the PN for my 2017 says 3G. So there might be a clean break between Gen1 and Gen2. Anyone know if there were significant infotainment changes between MY18 and 19?

I didn't look up the Plus PN because that was introduced later and didn't duplicate the photo above from @alozzy.

Looks like the same FCC ID is being used, so they would all use the same frequency allocation, thus should all be 4G compatible. Going by the pictures...

Thanks for showing that. You have met my criteria of "definitive". :D
