Wait, so in a building full of wifi signals, you could theoretically detect a body with no heartbeat or breathing and alert someone automatically?

- homero 10y agoPossibly, better get a startup going
- EGreg 10y agoSeriously, you can do this
- cannonpr 10y agoA more interesting question is who might be already doing this, and could you write a passive receiver for this to utilise ambient signals versus on purpose emitted ones. Considering it's utility in several scenarios, I can see why some money might be invested in developing this capacity without commercialising it.
