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.
This is going to be in every home in 10 years embedded in phones, TVs, smart speakers. All public venues. Trams, buses, subways. Everywhere. But most importantly homes. Every. Single. Person. 24/7. Breathing rate. Abnormal motions. Current location. Current activity.
Maybe, just maybe if we raise a some awareness we can curb the proliferation a bit.
Surely I can't be the only one who sees this as a nightmare.
Is it sensitive to noise or interference?
The VR headset application appeals to me. If headsets could be dumb terminals they would be a lot lighter and untethered wouldn't suffer from performance loss.
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...
