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.
