SETI Disrupted By Cell Phones in Airplanes?
Iphtashu Fitz writes "If, as recently mentioned, the FCC does allow wireless access on airplanes, could it effectively mean the end of the search for ET? NewScientist has a new article that explains how radio interference from airborne cellphones could drown out faint radio signals from space. Among other concerns astronomers have is that the second harmonic of many cell phones falls in a frequency band that reveals the molecular signature of newborn and dying stars, which is among the 2% of frequencies in this part of the electromagnetic spectrum reserved for use by radio astronomers. Michael Davis, director of projects at California's SETI Institute, stated that a single cellphone on an airplane 100 miles from a radiotelescope could exceed recommended radio noise levels by 10 times. A potential solution that astronomers have suggested is to install a miniture cell transceiver on each airplane, called a picocell, that would act as a relay using a frequency that wouldn't interfere with their work."
that's you buggered then !!

A mini cell on each plane that could play back a message saying something like "We told you not to use your cell phone, so turn it off!"

To get message, take amount of carrier pigeons at each stage mod 2. Then decode binary.
Still no intelligent life eh?
crazy dynamite monkey
this is why the aliens gave us cell phone technology.
always mosh clockwise
Well, there's the fact that you can't spell "extreme" even with an example right in front of you? Or wait, maybe that was intelligently designed?
It's not like they're going to find anything anyway... I do care about the interference with other astronomical work, though. And as if there aren't cell phones in enough places, damn, the last thing I want is to be on a plane with 50 people talking on their cell phones.
Too bad those little personal cell phone jammers are illegal in the States. Otherwise I'd carry one around with me. I'm sick of people too busy talking on the phone to drive, or walking down the aisle of the supermarket asking some poor nitwit on the other end of the phone, "Should I buy the ice cream? It's only got 9 million calories. Oooh, trash bags are on sale."
Maybe it's just me, but I don't want to hear people talking on their cell phone anywhere, but especially not in a crowded airplane.
I thought this article was about SETI?
Proud member of the American Non Sequitur Society. We might not make much sense, but boy do we love pizza!
ET: "Can you hear me now?"
SETI Scientist: "Damn cell phone interference."
this is one more reason not to have cell phones on airplanes during flight. I worry about the public's lack of concern for science especially given the extreme right wing movements going on
That's complete and total BS. Cell phone use on aircraft has never been proven to cause uncommanded wing or rudder movements -- on either side of the aircraft.
That sounds like some right-wing consipiracy theory.

I was quoted out of context in my autobiography...

We had better secure that then. It's difficult to stay in the air without wings.
