It's not a random noise if you can trigger it. Better to have the signal and the controlled noise if possible. You can't see the RF waves in the same way as sight. It is possible that the RF is ducting or has some other propagation phenomenon. And that's assuming you are even able to connect to the device and not just viewing it's location through the network, which could have precise location issues. Two sources are better than one.
Isn’t a signal that is within a few feet of the door you want to enter good enough? It’s more authenticate than some random noise - you know it’s your device and not some random device emitting find my data.
Sounds like policing or judicial approach is outdated. If a police officer sees the stolen goods inside via a window, they can enter right? How are RF waves that they can see coming inside the property, and uniquely identify the property, any different?
