Sure, if it's off. But most phones already have a fix most of the time, so unless you're coming out of a tunnel or something, it really shouldn't be noticeable. At least, I haven't noticed it.
And you can still get a pretty good fix from a cell tower. I'd rather that connection be more private, but at least it's between me and the service provider (and the cops I guess) and not some random person on the street. An attack on that would be far more sophisticated than a Bluetooth attack.
Ah, I'm rarely downtown, so that's probably why I haven't run into it. But wouldn't 5G triangulation largely solve this?
As for indoors, what exactly do you need the fix for? Surely you know where you are, so you can enter that into your maps provider if the fix isn't accurate. Seems like a big trade-off for a small inconvenience.
And for airports, I just look at the map. They're usually at every junction, so it only takes a few seconds to find where I need to go. Those maps are in the backs of airplane seats, so I just look it over while waiting to get off.
This seems pretty legitimate, but surely we can solve it with local AI (e.g. Google Pixel 8) instead of calling home. If I walk into a store and want a price for something, it should recognize the store I'm in and be able to recognize the product or whatever.
Doesn't it already? I get that even without Bluetooth enabled, so it's only working off GPS and cell towers. And this is with a super crappy phone (2020 base Moto phone). I've never had a problem with a bad fix for driving directions.
Yeah, that annoys me to no end. I don't care about losing the SD card slot, but I really like wearing corded headphones around the house since they sound so much better.
I'm not some tech Luddite or anything, and I have my fair share of Bluetooth stuff (shokz headphones, keyboard, mouse, phone, 2 laptops, desktop, etc). I just don't want my Bluetooth stuff tracked by anyone, especially not Google or Apple. In fact, the only reason I have an Android phone is because there's no viable third option, and Android helps me feel more in-control (I have a firewall and have disabled most of the default apps). I'm getting a Pixel next to (ironically) get rid of most Google crap with a custom ROM (they're really compatible with ROMs).
All I want is my things to securely connect with my other things when in range, and that's it.
I can't speak as to what everyone does, but normally on my phone, with Location Services off, normally that's not the case. The GPS circuitry only gets powered up when I open an app that uses the location.
Ehh...I don't know.
I haven't tried experimenting, but the range is pretty hefty on those. If you can see a given Bluetooth device at all, you have a pretty small area that you can be in. If you get a cell tower, maybe the signal is weak because you're a long way away, or maybe it's because there's a reflection, and only part of the energy is coming back.
A cell signal will put you in the right part of the world, but...
As far as I know, cell phones have no information about the direction of cell towers that they can talk to. 5G towers might use beamforming, but as far as I know, any location information that they may derive about the phone from that are not available to the phone. The phone provider might log it themselves.
I do recall watching a video of someone using a GNU Radio-based system, tracking down a radio station in a "fox hunt" using an antenna array on the top of their car. Basically, same thing in reverse. And based on the (limited) accuracy they got, I'm a little suspicious that the cell tower, even with beamforming data, isn't gonna have anything like the kind of accuracy that GPS does, even outside.

This might have been it.

I personally generally deny access, but a number of websites now request one's location to do things like provide nearby stores (e.g. look up an item, walmart.com will provide a list of nearby stores and the stock status of a given item). Being able to provide at least a general location is useful, which you can't do without a GPS fix; the accuracy doesn't have to be great for that, but you do have to be able to get it, and that's not necessarily the case indoors.
Like, use the camera to identify the location? I mean, maybe. That's a lot more passive processing that one is gonna have to do, if so. We aren't there today. And the reduction in data would have to be pretty dramatic. If you want to do something like that locally, for just walking down a street, you're talking about the Google Street View dataset. Are users gonna be expected to walk around with the camera recording and seed this thing?
I use OsmAnd, and it certainly tends to be sticky (I assume operating on the assumption that there may be error, and assumes that one is on the road that one previously was).
Yeah. I mean, I'm with you on that.
That's true of any radio, including Bluetooth, which is why triangulation is needed. It looks like 10 meters accurate should be feasible with 5G alone, which should be plenty for navigation purposes. Add GPS, and the article claims 1/10 meter precision. Maybe that's a little worse in a city with large buildings, but it'll probably be pretty close.
Yeah, I just type in a nearby zip code or city, and it works fine.
It could know what store you're in, but not which particular branch of that store. As in, it would know you're in a Bath and Body Works or whatever, but not the downtown mall outlet. That should cover most use cases, and the others could request temporary location access or present a list of possibilities. That way users know when they're potentially being tracked.
I don't know why it would ever need to know your precise location, it should be able to be very helpful by just parsing the environment and data (e.g. email) you've granted it access to.
Nah, just download it and cache it, and update it when home. Storage is cheap, I can get 1TB of NVMe storage in a tiny (M.2 2230) form factor for <$100. All OSM data is 100GB, so I highly doubt local storage would be an issue. The only limitations here are artificial (e.g. huge markups for phone storage now that SD storage is dead).
So from my perspective, we can solve the limitations here fairly easily, it's just Apple and Google trying to lock in customers. Maybe I'm missing something though, but avoiding most of that has gotten me pretty far.
