It doesn't transmit anything resembling a wifi frame (packet?), it's just noise as far as the wifi interface knows.. and not something that shows up on a wifi analyzer like linssid. You need a spectrum analyzer to see wifi noise/interference. I just took a quick look again for an affordable spectrum analyzer & didn't see anything. Then again, my definition of "affordable" is under $50 so I suppose that's not to surprising. Regards Lee
