I haven't heard anything about that yet, but they should be moving to 4G soon given this announcement:
Verizon Is Killing Off 3G Networks (to Make More Room For LTE)
As I recall, Tesla uses AT&T, so they're fine for now, but if this is the trend of things to come, Tesla will also have to come up with a retrofit for older cars to be upgraded as well.
This is one of the things I am waiting for before I order.
If I plan to own the car for about 4-5 years and I assume 4G is only a few months away, plus I don't need a car yet, I'll wait.
I wouldn't bet on that. For all we know the LTE engineer is for the Model X.
I don't see why they need an LTE engineer. It isn't like they plan to develop their own LTE chip. I'm sure they buy it from Broadcom or whoever.
Maybe a redesign of the hardware (i.e.: board/module).
I also don't assume it will be upgradable. I bet current owners are stuck with 3G.
Thus I'll wait. If I needed a new car now, that would be different. I really want the MS as I have test-driven it at least 4 times.
Just sitting on the sideline waiting for the free upgrade threads when LTE is made available...
The after warranty concern is the real thing keeping me from purchasing now.
YMMV.every tesla customer right now is super-early adopter. this is part of the package of being early adopters: tech not set in stone, at premium price.
personally, i would never get a tesla before 4g LTE. Terrible idea for a internet-heavy car.

According to the IHS teardown, the cellular modem is a
This is usually a plug-in unit and could easily be replaced with a 4G wireless module. May have to change the antenna also but the cable between the two should be fine. This should be a simple upgrade for existing cars.

To be completely precise, it's Sierra Wireless AR8550 chip: http://www.teslamotorsclub.com/attachment.php?attachmentid=45312&d=1395148747
It's capable of all HSPA bands and can get 14.4Mb/5.76Mb up/down speeds: http://www.m2mconnectivity.com.au/s...e_AR_Series_Automotive_Wireless_Modules_0.pdf Not sure if this speed is enabled in MS, some reports indicate that it is not.
The modem is implemented on a separate card, that contains the modem, the amp and the SIM card. Theoretically it is replaceable, but I would not necessarily hold my breath: there might be reasons why direct swap is not practical. Also, the existing antennas should work with LTE, since it's the same frequency bands, but then again, reality is known for throwing curveballs.
