Ramifications of a 3G car

Ramifications of a 3G car

Isn't 3G vs 4G vs LTE about hardware? If so, would it be even possible to upgrade this in the future to 4G or LTE (in an easy and affordable manner)?

I've found the browser to be very slow which kinda kills the experience of browsing on this beautiful screen.

Some people have suggested the 4G hardware is already in there, but Tesla is just utilizing a cheap bulk-rate 3G plan until the official data plan gets deployed.

Delivery Specialist told me that it would require a hardware upgrade.

The browser being slow isn't so much about the network connectivity, but rather running KHTML on a relatively low-powered platform (I don't know why they didn't go with Chromium which is much faster and also open source).

LTE is different for each carrier, so that seems unlikely.

My delivery specialist also told me its 3G hardware.

A product specialist told me that it has HSPA+ which some carriers consider 4G. Plan is currently 3G. No LTE hardware.

Not sure, but when I asked the product specialist at the store, one could connect the Tesla S to a wifi hotspot (via LTE mobile or VZW LTE Jetpack) to get your 4G speeds?

Anyone try this yet?

@CQN tethering to your phone's Internet via WiFi is coming in a future firmware update. Nobody can do or try it today.

It has 4g already. I took delivery last night and they specifically said it has 4g once they figure out carrier plans etc.

Once again TM can't get its message act together. I don't think anyone there intentionally lies, but I was specifically told in no uncertain terms at delivery that there is no 4G hardware in the car and none coming. You were told otherwise. DS need to learn how to say "I don't know." For now, apparently no one really knows outside of TM engineering, especially us owners.

@Pungoteague_Dave, I think part of the problem is that the definition of "4G" is more marketing vaguery than an actual technical specification. As has been mentioned, some carriers/phones market HSPA+ as 4G when they used to call it 3G. It got magically promoted when competitors started offering faster speeds. Back in 2008, the ITU-R defined 4G as being 100 megabits per second for high-mobility communications like in cars (1 gigabit per second for pedestrians).

Marketers thought that "4G" sounded nifty, and redefined it as 1/100th to 1/10th the speed that the engineers were talking about. Some marketers were more aggressive than others.

So It's possible that both Tesla people were in fact telling the truth: There could be HSPA+ hardware in there which would make it 4G by some marketers' standards, but might not be LTE which would be needed to call it 4G under other marketers' standards. There is likely no 100 Mbps-capable hardware in there, so the guy who said "no such hardware" might be an engineer too.
