it all comes down to part 15 of the fcc rules. the cell phone is a transmitter and when a device, say a pair of amplified computer speakers is near, it will act as a receiver and sometimes you'll hear the phones handshake to the tower. when i have my phone next to my laptop and my headphones are plugged in i can hear the handshake and know when a call or text message is coming in before the phone even alerts me.
What does Part 15 have to do with this other than stating a P15 device cannot cause interference, and has to be able to accept or reject outside interference?
"Morse Code" interference on speakers?
