I think that you are refering to binaural beats : http://gnaural.sourceforge.net/

You need a stereo headset to listen to this. There is a frequency in one ear and another one slightly off in the second ear. Your brain then merge the two sine waves and intepret both as a single, low frequency "beat" of the difference.

No, i'm saying that PWM-encoding data in microwaves produces low frequency beats in the final transmitted wave, similar to the frequency of binaural beats (~10-30hz alpha and beta brain wave range). I was joking that i could iDose with wifi in the same way as binaural beats. I'll try and find one of the papers.
