LTE service for Tesla S

I think that 3G issue with a bad signal, quality, performance, you name it, should be resolved ASAP. There are so many complains about 3G service quality. We all know that 3G is already "Yesterday". Today IPhone 5 works in many states on LTE and Internet is flying. TM should finalize their agreement with AT&T and we need to use at least 4G but better LTE service even if we should pay for it. Why should it be free? It's better to pay $ 50 and get what you want than wait for 3 minutes until next page opens

I DON't want to pay $50 per month. I'd rather tether my iphone 5 via wifi.

I still think that quality of service is more important than a few dollars a month for a service

Yeah, I get could 4G and LTE service around all the places I go, but the 3G service isn't great, and sometimes my car has lost a signal for several minutes.

we don't know who Tesla is using as provider, do we?

Most likely AT&T

If you think LTE is going to improve connectivity -- think again. In fact, coverage is much less, but you get faster speeds where you have it. So, if you are downloading huge files on the in-car browser, the extra speed will help.

@portia - AT&T. Personally, AT&T sucks worse than most cell companies around me, and I will be glad when I can put a T-Mobile SIM in once the free period is over.

We plan to tether an IPhone 5 typically.

The best case scenario would be if the system was unlocked like unlocked phones. People would be able to use their own providers and pay for them separately on their own.

@jat, in the Puget Sound area (Seattle), AT&T seems to have better 4G and LTE coverage than 3G coverage.

I noticed an improvement in continuous connectivity when I upgrade from a 3G phone to an LTE/4G phone.

Also in my last post, "could" should be "good".

Everybody knows that Verizon is the best service in USA but I don't think that Verizon is possible to use in Tesla S, so most likely it will be AT&T and as I said before 4G and particularly LTE makes internet 10 times faster than 3G. Those who like T-Mobile we can ask to wait until my request in MUST-HAVE thread of integration of IPhones, IPad, MacBook with Tesla S system comes to life.

Has Tesla published the frequency bands that the MS supports? Until recently, T-Mobile was using non-standard frequencies, forcing all iPhones to use 2G EDGE. When it comes to LTE, every carrier seems to be using different frequencies as well (you can't use AT&T LTE from a Verizon iPhone 5 for this reason, and yes the Verizon iPhone 5 has a SIM slot and can otherwise work on AT&T).

May want to think twice about "just swapping SIMs to carrier X" until we know about compatibility.

This is an uninformed and honest question. Why do we need the speed of 4G LTE? The browser does not support video/audio streaming or file downloads. Web pages might load a little faster, but is that really a problem? After a month with my S on 3G, I'm not having any problems with intermittent Internet radio or long delays with panes loading on Google maps. Do service providers use different cell towers for their 3G and 4G LTE networks such that 4G LTE is more reliable in signal coverage? Just curious.

@stevenmaifert I will skip the "is 3G good enough" part and answer the last half.

Because LTE is new, it has less coverage than 3G. In fact, it is so new that you cannot make a phone call over LTE yet, phones fall back to 3G (or sometimes called "4G" to hide this fact) to make calls. It will be a while before LTE "towers" outnumber 3G ones.

Technically, LTE uses different equipment than 3G (and 2G) but the antennas can share the same mast / pole / tower. But not every tower will have LTE overnight, carriers need to buy & upgrade the equipment one tower at a time.

In case you are wondering why voice calls don't use LTE, it is because older technologies had dedicated voice channels separate from data so it was easier to manage call quality over data. Now LTE is data only, using VoIP technology which is a huge switch. Carriers are hesitant to make this switch due to costs and until they have enough coverage to handle voice & data over LTE. Then they still need to convince 3G owners to buy new LTE only phones before they can retire 3G to make room for even more LTE.

Your digitized voice ... 8 bit version! :D


I'm happy enough with 3G. However, the extra large screen on the Model S does mean that the pages load quite slowly compared to my smartphone. It's a little like tethering my laptop to my phone, only worse because the screen is so big.

Okay guys. Thanks for the tutorial.

If you think LTE is going to improve connectivity -- think again. In fact, coverage is much less, but you get faster speeds where you have it. So, if you are downloading huge files on the in-car browser, the extra speed will help.

You got they right jat!,, go with Verizon if there's. choice

LTE would solve the issue of google maps loading slowly.

If you teather your phone, you lose the benefits of the smartphone app (unless the car can find a wifi connection where you park).

well, do you think we can add MS as a "tablet" on a family share plan for example? Then, it would only be $10/month more for those with family data share plan.

I would have hard time justifying $50/month for 3G connectivity at this time.

Somewhere in all this material (pages and pages) I read that the Tegra 3 cpu won't handle 4G and LTE and that Tesla should use the Tegra 4.

Anyone else know anything about this? Is it on the Tesla punch list? Who makes Tegra cpus?

maybe I am just totally off base and misinformed.

Where is the Tesla punch list - i can't find it and, as you know , there's no search on the blogs and forums.

@tobys1: Here is an example of a Tegra 3 using LTE:

So I don't think it is a limitation of the CPU. Just a matter of whether Tesla decided to use an LTE capable modem or not.

Put another way, WiFi is way faster than LTE and if the Model S can deal with WiFi, it should have no problems dealing with 4G or LTE.

Any other ideas, what would be the best for the internet service on Tesla S ?

@ jat-

When you say "you can put a T-mobile SIM in" do you mean the car or your phone? There is still that intriguing early review where the journalist referred to the car as having a swappable SIM. Anyone heard anymore about this?

This weekend, I drove a client's family around the Bay Area to help them find a neighborhood to move to (moving up from SoCal). We relied heavily on the map function but it was either way too slow or just a blank screen. This is someone who would potentially consider a model S. But after that experience, I doubt it. So frustrating. We had to use our tiny phones in front of this giant blank screen on the dash.

I called Tesla Ownership and they just point to the cell network as the culprit. But that's the point. If the car could have toggled over to 4G or LTE (as my iPhone does), there would have been no problem. And, if there's a hope for an upgrade, it will be a hardware solution (the car is not wired for it!). Our reality will be that us early adopters will be stuck with horrible 3G service. Basically, an iPhone 4 forever.

Once Wi-Fi is enabled, we don't need to use 3G anymore and can tether to any service we want. I'm waiting for it so I can switch over to my LTE-enabled smartphone or even my LTE hotspot.

You are not stuck forever.

Blaming a cell network for a terrible navigation system is the height of backwards.

At the risk of sounding ignorant, why do you need this 3G or 4G coverage? Is it for just software upgrades, browsing, and may be GPS?

~ Prash.

Software upgrades, browing, future remote services, and Google Maps on the large screen use the Internet. Today it is 3G, soon it will be WiFi which opens to door to other connectivity options.

@steven.addis - AT&T 3G sucks in the bay area. I visit once a month and my iPhone is almost unusable inside buildings and often drops calls outside. I feel for you.

The solution to the GPS issue is not network speed, as that is always going to be a variable. Google uses caching in Android and pre-pulls your route into cache. Google mapping also lets you pre-cache an entire area - only limited by your storage.

This would be an easy to implement solution and effectively end these kind of mapping issues.
