However, there should be an increase in broadband, if you were focused in the general area of the source.

Publicity hungry Snowden, maybe he just realised that he's borderline unemployable now and is desperate for attention.

He's confusing Snowden with the Brit what's his name. a reply to: chr0naut

This is perfectly logical. Remember the old day when tv signals were analog any you could turn your tuner to a station filled with snow (noise) on the screen. There were a few UHF transmitters in operation that would actually use a very small amplitude signal right before the video blanking signal of unused or undocumented stations to carry some data, a short pulse train then dead video information or hide it in the chroma channel of the signal. In any case anyone flipping through the channels would just see snow but if you had a decoder and knew which channel to look at, you could receive the bits, assemble the data stream over time and then unscramble/decrypt the payload.
Snowden, was just saying that we may not be able to find intelligent life once they move from simplistic communication methods to something capable of masking the activity which we can not easily discern, encryption offers a randomization of the data that can seem like just noise to anyone who does not know the methods employed.
He really had nothing to say that we wouldn't be able to surmise already.
As Professor Garrett explains: “The original research at Penn State has already told us that such systems are very rare, but the new analysis suggests that this is probably an understatement, and that advanced Kardashev Type III civilizations basically don’t exist in the local universe. In my view, it means we can all sleep safely in our beds tonight — an alien invasion doesn’t seem at all likely!”
Joking aside, Professor Garrett is still looking at a few candidate galaxies that lie off of the astrophysical correlation: “Some of these systems definitely demand further investigation, but those already studied in detail turn out to have a natural astrophysical explanation too. It’s very likely that the remaining systems also fall into this category, but of course it’s worth checking just in case!”
The technique applied by Professor Garrett can also be used to help identify less advanced (Kardashev Type II) alien civilizations that command more limited resources on sub-galactic scales. Such civilizations are still considerably more advanced than our own (Earth is not yet on the Kardashev Type I scale) but they might be more common as a result.
Professor Garrett has plans to look for these less advanced civilizations: “It’s a bit worrying that Type III civilizations don’t seem to exist. It’s not what we would predict from the physical laws that explain so well the rest of the physical universe. We’re missing an important part of the jigsaw puzzle here. Perhaps advanced civilizations are so energy efficient that they produce very low waste heat emission products — our current understanding of physics makes that a difficult thing to do. What’s important is to keep on searching for the signatures of extraterrestrial intelligence until we fully understand just what is going on.”

I wasn't aware snowden had said the gov were working with ET.
Perhaps im reading it wrong?
NSA leaked slide showing SENTRY EAGLE program where different DHS, DOD, and NSA clasified programs are hidden within less classified national programs. (NSA)
On October 10, Peter Maass and Laura Poitras writing for The Intercept, released more powerpoint slides from leaked NSA documents concerning highly classified programs that are hidden from public scrutiny. The documents, originally leaked by Edward Snowden, reveal that “Sentry Eagle” is used as an umbrella term for hiding the NSA’s most sensitive programs that are classified “Exceptionally Controlled Information” (ECI). Several powerpoint slides show how ECI programs are hidden beneath less classified programs as a cover. The leaked documents support claims made 16 years earlier by Dan Sherman, another NSA whistleblower, who revealed that he worked in a secret communications program with alien (extraterrestrial) entities that was hidden beneath less classified NSA programs as a cover.
