I've just used it for the point cloud data which can be streamed via USB. If you want to stream the raw data I think you'll need https://www.ti.com/tool/DCA1000EVM. it has a 1Gbps ethernet port on it.

quite possibly. i didn't dive down that rabbit hole so just said 'too early' ¯\_(ツ)_/¯

would be interested if you have any links about it

My original intro was about Snow Crash. Still waiting for mmWave on my skateboard http://pages.erau.edu/~andrewsa/Project%203/Thompson_David/S...

I agree that if all of a sudden our routers started mapping out the world like in the Batman movie that would be a bad thing.

I have a lot of experience with TI's IWR6843AOP chip and dev kit. It has 3 transmitters and 4 receivers and it'd be impossible to create a facial reconstruction with it.

My main point is the data is anonymous at source. I think having control over how that data is correlated back to an individual is important

Power consumption for radar can get down to around 0.5mW (edit)

But I imagine for 60GHz WiFi it's probably pretty power hungry.

At this point there's not much noise in the mmWave spectrum (it won't be competing with 2.4GHz and 5GHz anyways). And mmWave doesn't travel that far which is one of the main reasons the FCC unlicensed it in the first place.

Might be worth keeping an eye on UWB for AR/VR headsets https://www.embedded.com/wireless-transceivers-use-uwb-for-l...

technology is a political/legal problem. the printing press, gunpowder, the internet. technology has always been in the middle of political/legal problems.

There has been research done on gait recognition https://techxplore.com/news/2018-08-artificial-neural-networ...

mmWave can be used to identify unique traits http://www.cs.ox.ac.uk/files/10889/%5BDCOSS19%5DmID.pdf
