Some one turns on a motor, a TV, Microwave, etc There is a simulation of what it looks like, when a Wifi antenna is moved about within a household. https://www.engadget.com/2014-09-01-wifi-physics-signal-reception.html This is not a "perfect" simulation, but the intention of the grad student sharing that with us, is to point out how there are gaps. Radios work best when line-of-sight. And I've seen that with Bluetooth transceivers. I had one of those short plugin ones, and it worked a lot better when I put it on the end of an extension cord. And it also had line-of-sight with the other transceiver that was also using an extension cord. But Bluetooth is so slow, it's really hard to tell when a path is exceptionally good. It only delivers 75KB/sec or so. The Bluetooth signal should propagate in the room, just like the grad student simulation. Paul
