It looks like I have LTE enabled

[smorgasbord]

Previously, Model S used a Sierra Wireless 3G modem (AR8550 to be exact), based on a Qualcomm chipset, and for the AT&T network:

It's part of Sierra Wireless' AirPrime "AR" series, which of course has supported LTE since 2014:

So, there will not be a software upgrade to LTE - the best you can hope for is a module swap on the board, but that's assuming Tesla had previously chosen an LTE compatible antenna.

That's a very expensive solution for storage. A flash capsule on the board is much much cheaper...

If it is indeed used as cache/swap, it probably gets a lot of writes and the NAND will deteriorate rather quickly. Maybe they expect to replace it often so went with a MicroSD card instead of a fixed flash chip on the board?

 

[Ingineer]

If they were smart, they only cache tiles close to your normal driving area (i.e. Home) and leave them there for awhile, thus reducing the number of writes.

Actually, the very earliest Model Ses used the precursor to this chip which was not LTE capable. Sierra Wireless EoL-ed that chip and switched to the newer chip somewhere in the summer of 2013, so depending on how many of the older chips Tesla had on hand, they likely moved to the newer chip in the summer/fall of 2013.

With a bit of luck, many folks will simply need an antenna upgrade to get LTE, but for the earliest owners its probably going to be a bit more complicated.

My MS ended production on June 4. Got it on June 25. It has LTE.

Picked up my 85D on June 26th. It has LTE.

Anyone with LTE done any traveling to Canada? I have a 3G 85D and it has unlimited Canadian data roaming, which I wasn't expecting, but love. I'm curious to know if LTE models have the same roaming setup.

Picked mine today I have LTE too - And she is blootiful!

For those that are wondering, all that's changed in the Touchscreen is the modem/GPS module, so in theory, it would be possible to retrofit it, just a LOT of labor.

Here's what it looks like:

Perhaps the new part will also improve the wifi.

No, the wifi comes off a separate module made by Parrot. As far as I can tell, they have not updated it.

Any change to the antennas?

Thanks for sharing! Always cool to see internals of the car. Is that a SIM on the bottom left? Also, did you take this photo, or get it from somewhere else?

Still no word from Tesla on retrofitting?

Retrofitting cost and availability is currently scheduled for announcement in the fall according to several different sources

Fall of what year?

I think the Canadian roaming is pretty new

I just traded an early 85 for and 85D (built at the end of May - no LTE - booo). My old car shut down reception at the border. I was very pleasantly surprised to see if work when I went to Vancouver airport recently.

Exactly!

Pretty confidant in your prediction, aren't you?
