Trying to pronounce this is the hardest thing I’ve ever done

lol, thanks. fixed it

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

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 an

technology is a political/legal problem. the printing press, gunpowder, the internet. technology has always been in the middle of political/legal problems. can't be evil > don't be evil.

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&#x2F

all sensors/technology are invasive to a degree, but I would argue radar fairs well in usefulness and anonymity in comparison to other sensors. if the data were leaked, would you rather have some of your vitals and point cloud data exp

most hall effect sensor applications i've seen use a schmitt trigger and output a digital (on/off) signal

thats a good point about the hall sensors. i'll update that. PIR sensors also output an analog signal, but in practice they are binary.

there is a risk of being jammed or spoofed which is why there has been a bunch of research done in the automotive industry. https://www.caee.utexas.edu/prof/bhat/ABSTRACTS/SecurityOver... But I don't thi

I've been following and building mmWave radar stuff for a little over a year now and I wanted to write an intro to help anyone get up to speed on how it works, why it's special, and what's been happening in the space.
