Future Retrofit - LTE —> 5G ?

edited November -1 in Model 3
So since the latest and greatest available today is LTE and 5G is on the horizon... Will tesla be selling an upgrade to the newer standard in the future?

On a related topic, why does the WiFi get disabled once you start driving, I would really like to enable my hotspot device to the WiFi (This could also be another work around to a 5G solution).

Intent of the question is, how upgradable is this car or is it meant to be e waste and just toss it in the trash and go buy a new one?


  • Seeing as how LTE 'does the job' of streaming your MUSIC, letting you browse the INTERNET and streams NETFLIX/HULU without having to constantly pause - I'd say there's pretty much a zero chance of retrofitting to 5G on these cars. Why spend the time and money when the job is getting done now.

    As far as not HOTSPOT service - that's again due to cost. If they gave it to you, people would most likely gobble it up, costing them more money. I suppose it could be offered as an added expense, but I would not hold my breath thinking it's going to be added for free.

    They are going to skip 5 and go straight to 42.

    They are charging for premium service now, they could charger for the hotspot. I was happy to give Onstar $20/month for a hotspot and I'd be happy to give $20/month to Tesla for the same service.

    As for 5G, it won't be very helpful in a car. You don't need 5G speeds for navigation or streaming music. You don't even need it to stream Netflix. The primary application for 5G will be to replace cable or FIOS on the last mile.
  • No one can see the future but I would expect that Tesla will be producing cars capable of 5G. That being said, you will likely need to trade in your existing LTE equipped Tesla if you want the latest and greatest 5G model.

    This will have a positive impact on new car sales but it will have a negative impact resale value of existing
    LTE equipped Teslas. All Tesla owners understood this when we bought our Tesla primarily for its leading edge technology.

    Back in the day I paid $500 to upgrade my 2014 Model S from 3G to LTE. The upgrades became available a few months after LTE became standard. Probably in 2015 or 2016. 3G "did the job" but I wanted the latest and fastest.

    Voice recognition would definitely benefit from 5G.

    It's not YOU that would necessarily benefit from 5G, it's Tesla. It would allow them to increase their driving data set collection dramatically.
    Just like it's worth it to Tesla to include FSD hardware even in cars with no FSD...for the data.

    If anyone would, it would be Tesla, unlike BMW who told people to pound sand when their 2G service went unsupported.

    Until "5G" really means the same across carriers and bands, 4G is a better bet.

    The Nissan LEAF of earlier vintages came with 2G. When disabled Nissan offered a $199 upgrade to 3G by replacing the telematics control unit. Nissan absorbed whatever cost was above that number including labor. That’s the good news. The bad news is the new TCU was very problematic causing some owners to have to reset the TCU very frequently by pulling the fuse. I was one of the lucky ones and had no issues with the new unit until it died a year later out of warranty. Since the vehicle can only go 30-35 miles, I opted to not do the repair.

    @fazman: Although WiFi disconnects when you shift into gear, you can touch the LTE icon to reconnect to WiFi if you want to use your phone as a hotspot while driving. Other people do this. Just make sure your phone's data plan is up to the task.

    Was FAZMAN misunderstood? Was the real question, "why can't I use my own hotspot to continue premium connectivity on the road, and not just while stationary?" Doing so has zero impact on Tesla's data costs.

    Just saw response from EVRider. Will need to try that.

    @Magic 42 is not the answer. I think Tesla is going to go to 11.

    But is all seriousness. The killer app for G5 will be better communications between cars. How much smart will FSD be if it knows what the Tesla that is 3 to 10 car lengths ahead sees and is doing ?

    Only thing I see in the OP is:

    " it meant to be e waste and just toss it in the trash and go buy a new one?"

    A carefully crafted dig at Tesla is all I get from it.

    I dont see how a vehicle would ever need more than 4G upload/download speeds.
  • A Tesla M3 is analogous to a frosty mug of beer. The foamy head is all the cool high tech features and the liquid beer is the safe and reliable transportation it provides.

    So even when the cool high tech stuff gets old and dated, the M3 will still have value if it provides safe and reliable transportation. Personally I wouldn’t feel the need to upgrade to the latest and greatest model if my trusty SR+ gets me to work every day and doesn’t become a money pit.

    @Magic: You are a troll, you add no value to any discussions.

    @plugzin: Yup you understood my intent

    @Andy: I have no idea why any computer would need more than 640k of ram

    @mrburke: Agreed, thats why i am hopeful they thought about it and its hopefully a simple plug and play swap, if not than piggy backing on the wifi of an external hotspot should do the trick for a 5G work around.

    @EVRider: thanks for the tip, i will try that!

    @ibowroom / @SalsburySam: Yup, had the same issue with my 2G BMW Assist on the e90 (I still have that car with 190k on the clock).

    @RXLawDude: Thats fair, but i’m just stirring the pot in hopes that if no one has thought about it yet... maybe it will be looked into before it is needed. I give it a hand full of years before LTE is shut down.

    @ majassow: Very true indeed

    Intent was clearly stated.

    [email protected] You are right that vehicle to vehicle communication would benefit from 5G, the short range of highband 5G would be ideal for that application. However by the time V2V is implemented we will probably be in the 6G generation. V2V requires a single worldwide standard to work, it does no good for Tesla's to only be able to communicate with Tesla's and Chevy's with Chevy's. V2V will offer some huge benefits. V2V could make a big difference in road congestion, if self driving cars could talk to each other you could have virtual trains on highways which pack cars much closer together then is possible with human drivers that are limited by human reaction times. Virtual trains would be more energy efficient then cars running at today's spacing, they wouldn't be subject to the same traffic jam effects that we experience today, as a result the same road could carry many more cars at higher speeds. But that can't happen until there is a standard, which is probably years away, there are enough cars that implement the standard, and that laws change to create virtual train lanes that are restricted to self driving V2V vehicles.

    not sure how computer RAM has anything to do with internet bandwidth. No, i dont think Tesla vehicles should use 5G, not only because 5G has a very short usable distance, but because the car will never literally ever require that kind of bandwidth demand. Even when FSD gets to level 5 - kick your feet up in the back seat and watch netflix, Netflix can stream 1080p no issues using 4G capacity. But ultimately, whatever the Tesla vehicles use for internet, will more than likely be coming from starlink. So my opinion is relatively invalid.

    5G spreads CV-19. /s

    Backstory: people are burning down 5G towers in the UK.
  • edited April 6
    wtf? i would be burning them down because they're being deployed without making sure the 5G radiation band wont have health consequences. People really do dumb things.
