Every time I read one of these pieces I seem to have the same question. I can't seem to tell if this is much ado about nothing, or if there's actually something to this. It's like they've observed something but in order to understand what they've observed you have to divide one dbm above the noise floor into 10,000 tiny pieces, and what they're trying to find is in the very first segment of those 10,000 divisions.
It's kind of ironic actually; the phrase..."I can't tell if this is real, or if it's just 'noise' (floor)."...really seems to apply here.
I've spent many hours staring into a spectrum analyzer trying to chase 'ghosts' down around the noise floor, but most of those ghosts were 9,999x larger in magnitude than what they're talking about here (and yet these anomalies were still so small it was impossible to tell whether they were a product of normal background noise or something real). But again, maybe I'm not understanding.
And then there is what F2d5thCav talking about too..."Where in the spectrum are we talking about here? They never seem to say. Are we somewhere in the normal RF spectrum (i.e. ~ 3kHz to 275 GHz), or are we talking about some exotic frequency so far above or below the normal RF spectrum that there isn't even test equipment to measure it?"
Once again...is this just "noise" or is there something to this?
