Kinda crazy the arc that 60GHz has taken over the years.
Like ages ago it was going to be Intels docking station standard (WiGig). It died, companies like IgniteNet bought up all the Dell wigig chips, and used them to prototype P2P wireless radios, ultimately building out a new class of metro p2p wireless used by every major vendor. Then it became a component of 5G, mostly used for backhaul but still capable in a lot of Massive MIMO handsets. Some handsets trialling it for in home wifi. And now the chips are probably going back into your laptops/Homes to detect your biometrics.

Not even 60GHz. We're talking 2.4/5 here
Oh thats cool. I just saw a reference to ESP32 and I know they do a 60GHz heart rate unit. Some HA guys have been using it
The 60GHz heart rate sensor you're talking about (this one maybe https://wiki.seeedstudio.com/ha_with_mr60bha2) can be used with any microcontroller. It's got nothing to do specifically with ESP32, which is just one kind of microcontroller you can use it with.
