1. For the most part, approximate location of devices was performed
by measuring the received signal strength (RSS) from multiple Wi-Fi
access points (APs) which offered 10-15 meter accuracy at best.
2. Android added support for Wi-Fi RTT with the release of Android 9
in 2018, and many mobile devices today have Wi-Fi chips that support
the positioning technology.
3. The IEEE Standards Association created the 802.11mc, or Wi-Fi Round
Trip Time (RTT) standard to allow for more precise Wi-Fi-based
positioning. This standard uses Fine Timing Measurement (FTM)
to enable location tracking with 1-2 meter accuracy.
4. Instead of relying on signal strength measurements, Wi-Fi RTT
with FTM measures the time-of-flight (ToF) between an RF packet
sent from your phone to several nearby APs. While Wi-Fi RTT with
FTM worked over both the standard 2.4 & 5GHz bands, it was never
widely deployed in the field, so youâ–”e probably never used it
5. While Wi-Fi RTT with FTM is already fairly accurate, the IEEE SA
was able to improve upon it even further with the 802.11az standard,
also known as Wi-Fi Ranging. Wi-Fi Ranging with FTM allows for
<1 meter accuracy (down to 0.4 meter), so it┬ even more accurate
than Wi-Fi RTT with FTM. Not only that, but it uses double the
bandwidth (160Mhz vs. 80MHz), supports the 6GHz band, is scalable
to a large number of clients, is more secure and protected,
and supports dynamic measurement rates.
6. 802.11az Wi-Fi Ranging can only work on Android 15 devices with
Wi-Fi chips (such as Qualcomm┬ FastConnect 7900 connectivity chip)
that support Wi-Fi Ranging but Wi-Fi Ranging is slightly less
accurate than Ultra wideband (UWB) and Bluetooth Channel Sounding,
but 802.11az Wi-Fi Ranging has better range than UWB & BT has.
7. To take advantage of 802.11az Wi-Fi Ranging, any Wi-Fi access
points (APs) that support Wi-Fi 6 or later will likely need to
burn in a firmware update to support 802.11az location tracking.

Similar to the privacy implication of Satellite GPS (Garmin and others),
and the current cellphone with the tracking app that allows you to
locate the exact position of another phone, and similar systems.

This may be a silly question but why would a phone be sending
anything to APs that it doesn't know and therefore cannot use?

To rephrase the above, any device that emits a signal can be tracked and located with the proper equipment.
This has been going on since the first electromagnetic signals were sent into the air.
The only what that you can avoid tracking to find your location, is to
turn off, or get rid of all devices that emit a signal, cell phone,
pace makers, etc.

The only what that you can avoid tracking to find your location, is to turn off,Â
or get rid of all devices that emit a signal, cell phone, pace makers, etc.
If the reading
never leaves the disk drive housing, then there would not be any
privacy implications.
When a cellphone has an accelerometer,
or it is measuring the electrostatic charge in the air, hardly anybody seems to be interested in "why did they put this crap in my phone?".

We have successfully eliminated being tracked in the Wi-Fi AP databases,
so why can't we just as successfully avoid 802.11az Wi-Fi Ranging tracking?
You need to keep the question in perspective since we're NOT talking about being tracked when you're out in the open, sleeping, driving, or hiking.
We're talking about being tracked to the half-meter level *indoors*. Specifically inside of business establishments (who have a motive).
All the morons on earth exclaim "We're doomed to be tracked" simply because
a cell phone, by its very nature, gives out emissions which can be tracked.
We are not those morons. We are intelligent. We understand technology.
Which is why this question was being asked *specifically* to better understand the privacy implications of the specific 802.11az Wi-Fi Ranging.
This is *new* technology - never before seen in cellphones.
We are not morons.
We're intelligent people.
I'm not sure yet what the privacy implications are of this new technology. But I am sure that giving up and surrendering to it is not my intent.
Yours shouldn't be either.
We're not slaves. Slaves give up and accept everything done to them.
We are not slaves to technology.
We control it. Not the other way around.
This question is the first step in controlling this new technology, particularly when used by businesses for half-meter tracking of us.
