"One of mmWave's major advantages is its privacy-preserving nature. Because mmWave radar doesn’t process visual light, what it sees is not personally identifiable." Bullshit!
Perhaps they mean it skirts current privacy rules through legislative technicality.
Do any of you see avenues for a conventional radar company to contribute to this emerging trend? We produce high-end FMCW radars ( http://dopplerradars.com ) and I have been looking for ways to align us more with Tech and less with Defense.
As a guy that works on old cars (and drives them fast) that will never have OEM support for e.g. ADAS, I'd love to have access to a small, discreet (i.e. not visually excessive, but "hideable"), modular set of sensors that could be used to build e.g. ADAS/parking sensors/(pipe dream) automated driving. I'm sure the OEMs would be interested, but I'm looking for something I can retrofit.

Right on. The whole "mm wave radar is detail rich but gives privacy" line is a contradiction. Any data that is detailed enough to be useful is detailed enough to be a privacy concern. While it might not be the same as leaking nude photos from someone's camera, radar data is something that needs to be carefully thought out. Radar data from a car can provide information about people's driving behavior even without loca…
> leaking nude photos from someone's camera whatever happened to that meme about common ccd cameras picking up uv images that make out details through eg swimsuits, but hopefully filtered and removed in software before making it to the images?
If it’s IR… I have a PVS-14, I’ll have to dig one of my wife’s swimsuits out of the closet and see if it’s transparent. I’m curious.

You could argue that today's circumstance is why you DON'T need explicit laws prohibiting workplace monitoring. Anyone with the desire could set up such systems today. But they don't. Because they're expensive, inaccurate, and ultimately not all that useful in the social context. There are places that do employ such monitoring, but they're a corner case. Trust is a core commodity in the workplace. It's usually more p…
> There are places that do employ such monitoring, but they're a corner case. Don't amazon warehouses already monitor workers in this much detail? Just yesterday I read someone talking about how managers get reports containing, amongst other things, how often a person was standing still. Lots of companies squeeze their employees like this, especially low paid employees.

Or just add a near infrared filter to cameras. Much easier and can even be mandated by law if necessary.
No. I can rip off infrared filters from any camera I own. I already do that, because I image nebulae and galaxies and sometimes landscapes in infrared.

You do realise that you have to add this to every swimsuit on the planet, right? And all other clothes that may exhibit it this behaviour? It is not the material that’s buggy, it’s new technology which can look under clothes and damage privacy that’s the problem.
No. That's like saying thieves are the problem so tie up the hands of every would-be thief and don't bother lock doors. It's much simpler to lock doors, and that prevents thieves 99.9% of the time.

I opt into carrying a cell phone and it’s when I want. I don’t opt in to my neighbor’s Alexa tracking my comings and goings by scanning through my walls.
You can do that by sniffing wifi packets even if you can't decrypt them, I think? Could be a good opportunity for home Faraday cages.
Very dumb question: If mmWave is operating at 60GHz, how would it be possible for processors (which are operating at less than 1/10th of that clock rate) to process that sampling rate?
In summary, 60 GHz is the CARRIER frequency (the central frequency) around which a modulated signal is centred or otherwise aligned. The modulated signal BANDWIDTH (channel width) is where the signal information is encoded and is going to be measured in Mega-Hertz (MHz). E.g. for 802.11a/n/c the CARRIER is in the 5.x GHz band but the modulated signal BANDWIDTH will be one of 20, 40, 80, 160 MHz around a central frequ…

I don’t emit WiFi packets nor do I carry a device that does.
