  • The final cut of the 9th episode of the Tesla Motors Club Podcast, featuring Chad Schwitters, the former president of Plug In America, is now available. You can watch it now on YouTube or listen to it on all major podcast networks.

Let’s talk about something other than ordering, which cell network Tesla uses?

From what I heard, the contract is with AT&T and normally roams to Rogers in Canada. I hadn't heard about a Canada-specific contract for the data connections.

Wifi might still come to Model 3 as a software update (supposedly the hardware is there), but as @seanxushen says, it's not currently available.

If it uses roaming kind of service, the cell chip will pick up the best signal available and try to register.

Generally yes, but not necessarily.

With roaming configurations, there are preferred roaming partners, and Rogers is a preferred carrier for AT&T roaming in Canada (and the inverse is also true the other way as well, with AT&T being the preferred roaming carrier for Rogers in the US). However, (and this depends on the phone and it's cell phone network selection criteria -- they are all a bit different as different vendors tweak the algorithms supplied by the radio firmware vendor, typically Qualcomm), they will roam to other networks as well based on signal strength, so long at the network technology is compatible. In Canada, our networks are now all generally aligned and compatible (in the US, Sprint and Verizon are still either quite different, or a bit different).

Also, in Canada we now have these "EXT" (extended) networks for roaming, where each carrier can roam on to other carriers networks. I'm not sure how that works if the based network contract is with a US carrier, but people may have seen their phone "roam" (it's not billed as roaming though, due to legislation) onto the EXT network (which is actually a network of another carrier).

Note I am ignoring cellular band support of devices and networks, as there are usually common frequency bands on the different networks to allow phones to roam/switch networks more easily (and most cellular terminals have support for a wide variety of bands in single chipsets these days).

As to how the mobile terminals inside the Tesla's work, I cannot tell you specifically -- the above info it just based on a number of years working in the cell phone business.

Looks like professional talking. I used to work for Newbridge if ppl still remember that 2nd largest telecoms device company. And you?

I was at a Newbridge affiliate (Crosskeys) for a bit about 20-25 years back (hard to remember these days). My wife worked in the cellular radio area at BlackBerry for a number of years, and I also worked at BlackBerry for just under 5 years as well. So, I've been around cellular a bit.

As I understand, Internet is only included in the car for a few of years. What happens when that ends? How do you get maps for GPS?
It seems like Tesla hasn't bothered to start charging anyone for data yet. I suspect at this point they don't care. The vast majority of their cars are only 1-3 years old and they will cross that bridge when it's justifiable to put the resources on it.

I think they're still at the point where it will cost more to set up a payment system than what it will earn. Plus the effort is better spent elsewhere.

In the long run the car can connect to wifi, so one solution would be to connect it to a cellphone hotspot. On my Rogers plan sharing your data with a second device costs $10 a month. So stick an old phone in the car and done.
