Edit: It seems I'm wrong. Channel sounding requires an encrypted connection. It's not something that can be done between a passive device and your phone.

It will allow things like secure entry (walk up to a door and it opens, be near your car and you can open it), finding your devices (lost keys, headphones, remotes, etc.), auto-unlocking for your laptop, and more.

--------------

This is a really cool technology that is going to allow essentially indoor GPS. Imagine going to a mall, and you open a map on your phone, and it immediately knows where you are to under 1m error.

halapro•2mo ago
Do you still need "satellites" installed indoors to work? Because then you'd have to convince every business that this cost has a direct positive effect on their sales.

A lot of brick and mortar stores are based on the assumption that a lost customer will buy more things, so I don't see this happening.

rtutz•2mo ago
Think about how this information could be used. As a store owner you can precisely track movement of customers and optimize the shop layout.

BT hardware is also rather affordable.

AlotOfReading•2mo ago
You're already tracked like that. I was building solutions to do it well over a decade ago. One customer was well known for their mouse themed hats. A famous hotel brand in a well known casino city used it to track employees instead. I no longer do that for obvious ethical reasons.

There may be a rare few legitimate uses for improving the accuracy, but it also makes those privacy nightmares worse.

kenhwang•2mo ago
My previous employer already had a product offering that could do this for a better part of a decade by triangulating with WiFi/BLE and cross referencing with surveillance footage. It was deployed in malls and retail chains.

It generated interesting information, but not interesting enough to be profitable.

We weren't the only ones with this capability either, most major retailers had this level of analytics through surveillance footage that previously existed for loss prevention purposes. Then simply link the data to a rewards number or credit card and you got a stable tracking identity.

> loss prevention

So preventing theft?

meindnoch•2mo ago
No, loss prevention. :)

"Theft" is such a value-loaded, moralizing term. It collapses a wide spectrum of socioeconomic realities into a single criminalized label, ignoring the structural inequities that often shape people's choices. When we say "loss prevention", we're deliberately reframing the conversation away from individual blame and toward systems, environments, and institutional responsibility. Loss prevention isn't about vilifying people - it's about acknowledging that harm occurs within a broader context. It centers the idea that organizations can design safer, more equitable spaces that minimize material loss without resorting to punitive narratives rooted in classism, racism, and centuries-old assumptions about who is "dangerous". Calling something "theft" externalizes accountability onto the most vulnerable actors; calling it "loss" recognizes that institutions have agency, too. And preventing that loss focuses on proactive, compassionate strategies rather than reactive punishment.

luma•2mo ago
The industry tends to use the even harder-to-understand term "shrink". Not always theft, just any loss of product versus what the books say they should have.
kenhwang•2mo ago
Theft is only one cause of loss. Stocking/admin/counting mistakes, accidental damage, spoilage, or simply people moving stuff around or misplacing items so they're not where it's expected all fall under loss.
luma•2mo ago
I've worked with a major retailer on similar backend systems and can echo the post above - all of them are running these systems and they almost never discuss the specifics (until someone like Walmart sues Everseen and we get a glimpse behind the curtain from the court documents).

If you go to an org's website offering these tools (eg, Everseen mentioned above, RetailNext, etc), they don't directly advertise the full breadth of their capabilities until you have them in a room for a sales pitch. They can combine multiple data streams such that an individual can be traced throughout the store via cameras, wifi, and bluetooth, which gives the retailer an opportunity to sell that information. Did a customer pause in front of the corn chips but then decide not to buy? Print them out a Frito-Lay coupon at checkout and see if you can't get them next time, and Frito-Lay will pay you to do that.

porridgeraisin•2mo ago
That's so cursed. I suppose since the source of the money here is the manufacturer, this only happens in major retailers with large shops?

Do you know if smaller shops in india/asia also make use of this?

luma•2mo ago
I have no first hand experience outside of North America so I won’t speculate. There is a cost of entry so you need to be moving enough volume in a market already working on razor thin margins. I’d expect that this means it’s only for the regional/national players here.
porridgeraisin•2mo ago
Ah ok so just to confirm the providers charge the store per user entry? That gives me a good idea of who would go for it. Thanks
luma•2mo ago
Sorry, "cost of entry" meaning that the software and the supporting hardware platforms makes it cost prohibitive for a small org that isn't moving a lot of volume from their shelves. Grocer margins are razor thin already.
jacquesm•2mo ago
And guess what, that shop layout is not going to be optimized for the customer's convenience, but for the shop's profits. These kind of solutions tend to converge on the 'Hotel California' model: you can enter, but you can no longer leave.
op00to•2mo ago
I work with retail stores who do exactly this in a number of different ways! Many chains are already populated with all kinds of BT sniffing(?) equipment. At least one pings RFID tags in everything every 5 seconds. It’s wild.
jacquesm•2mo ago
Indeed, screw IKEA.
atoav•2mo ago
Maybe US IKEA is different from European ones, but there are literally arrows on the floor that guide you through the whole thing? Follow the arrows and you're out.
jacquesm•2mo ago
No, they don't guide you to the exit, they guide you past the collection.

The whole point is that the thing is set up like a very long serpentine track so that you 'see everything' rather than that you can go to the one thing you want and then to the cash register. This is because they - rightly - figure that if they can keep you in the store longer and expose you to more stuff you might buy more.

MSFT_Edging•2mo ago
You can enter the warehouse directly through the register area. No one is stopping you.
jacquesm•2mo ago
Oh, that's a neat hack. I will definitely try that next time. I have a bad leg (bike accident) and the extra walking really pisses me off. I don't need a stick or other help but I do economize on unnecessary walking on hard surfaces. Thank you. Ikea has killed all viable competition here so you can't really get around them.
MSFT_Edging•2mo ago
Another tip, there's usually an "offramp" in the later part of the showroom grand tour that goes to the cafeteria section. You can also jump straight to the cafeteria from the entrance at most ikeas I've been to and enter the showroom there to get a shortcut to the lamps and things.
op00to•2mo ago
The IKEA near me also has shortcuts, but if you go in through the “loading dock” you should be golden. We also have an even closer IKEA mini location where you can order from a tablet and have orders brought from other stores.
atoav•2mo ago
> No, they don't guide you to the exit, they guide you past the collection.

I did not claim they guide you to the exit. What I said is that you don't get lost if you stay on the path. A scenic route to the exit is still a route to the exit.

Also: if you want to get to an actual exit it is mandatory (at least over here) to have clearly visible, emergency exit signs so people can get out in case of fire.

jacquesm•2mo ago
I am not afraid of getting lost. I'm annoyed at having to walk more than strictly necessary on account of a less-than-perfect leg.
atoav•2mo ago
I mean IKEA offers a service where you can pick stuff online and collect a d does even do home deliveries. Meaning if you have to avoid walking it is certainly possible with them.
spockz•2mo ago
Every IKEA around here also has various shortcuts that you can take at any time. Even from entrance almost directly to the warehouse. These are also indicated. So it is a choice whether you want follow the whole route for inspiration or not.
jesperwe•2mo ago
I can imageine that. Although not using Channel Sounding, as it has a accuracy of +/- 200mm according to TFA. Which is still very good, though.
flowerthoughts•2mo ago
I don't follow your reasoning. (+-)200 mm is better accuracy than 1000 mm.
jesperwe•2mo ago
1m? 1mm? Apparently I was seeing double
vardump•2mo ago
In case you're not familiar with the metric system: 1m is 1000mm. In other words, one millimeter is one thousandth of a meter.
srcmax•2mo ago
New devices, such as Pixel 10 already support channel sounding. Basically it's alternative to UWB. One phone sends signals on multiple frequencies, another receives them. Obviously devices should be connected via BT. Also tracking people already works with BT/WiFi RSSI (signal strength). Channel Sounding works better because it works even when the signal line of sight is obstructed, for ex. headphones lost under pillow.
styanax•2mo ago
How do they compare in actual use? I have a Pixel 6a connected to $40USD bone conducting headphones and the range and punch-through are incredible; the phone is sitting in the living room playing music and I can almost make it to my mailbox at the end of the block (about 3 houses away) before it starts to degrade or cut out.

Do these alternatives compare with just how well UWB serves regular, normal daily activity like this? Because to me, what I have is absolutely excellent in use with daily routine.

olirex99•2mo ago
I am pursuing a PhD in indoor localization, and UWB is still far superior. That is the reason why major phone companies still include a UWB chip and are not switching to BLE 6.0.

I have compared them, and because BLE is a narrowband signal, it is highly susceptible to Non-Line-of-Sight (NLOS) conditions compared to UWB.

I also attended a prototype presentation by a large European silicon company. I noticed that even in their demo, BLE did not achieve 30 cm accuracy, but rather hovered around 1 m.

I have only tested PBR and RTT ranging with a simple Kalman Filter, so maybe someone has found a clever combination of these data sources (I hope).

pwarner•2mo ago
Is there a good list of cars that support UWB? Seems like a requirement for my next car...
olirex99•2mo ago
All the new car have the keyless option and use UWB to open and close.
skzv•2mo ago
Cool, I worked on indoor localization, particularly with RTT, at Google for many years :)
olirex99•2mo ago
Maybe we can get in touch, I am curious to have a more senior perspective on the indoor localization!
