DARPA's Latest Grand Challenge Takes On The Radio Spectrum (gizmag.com)
An anonymous reader quotes a report from Gizmag: One of the most hotly contested bits of real estate today is one you can't see. As we move into an increasingly wireless-connected world, staking out a piece of the crowded electromagnetic spectrum becomes more important. DARPA is hoping to help solve this issue with its latest Grand Challenge, which calls for the use of machine-learning technologies to enable devices to share bandwidth.
The Spectrum Collaboration Challenge (SC2) is based on the idea that wireless devices would work better if they cooperated with one another rather than fought for bandwidth. Since not all devices are active at all times, the agency says, it should be possible through the use of artificial intelligence machine-learning algorithms to allow them to figure out how to share the spectrum with a minimum of conflict. DARPA announced the competition in front of 8000 engineers on Wednesday at the International Wireless Communications Expo (IWCE) in Las Vegas. SC2 will run from 2017 through 2020 with teams competing to create radios that can collaborate most effectively with other radios. The competition will end with a live event and the prize is $2 million.
Perhaps the Tay-based devices can give preference to the wireless devices with blue LEDs.

Hmm divine massage. Would probably fix my back..
They give like a 1000%th percent of the spectrum which can be reasonably processed and sent across a reasonably long enough distance today away.
The other 999%th percent they steal from the public.
We're out of spectrum. It's all being taken up by AM, FM, Sirius/XM, SETI, wifi, and CT scanners. There's no spectrum left.
Hopefully they have a team of scientists working on ways to create, clone, or grow more spectrum.
Someone call Jesus!
Maybe you could combine this with their other project they recently announced and create a weaponized AI that does its best to subvert their desired outcome.
Our country is doomed if the socialism continues to befall this great nation UNITED UNDER GOD.
GOD will punish you if you vote for sanders or hillary. He has cursed both of them.
Fire will rain on american soil if the democrats continue to rule.
wasn't that the Evil on Man from UNCLE?
You will be absolved if you vote for trump. He will save this nation, and voting for him will save your soul. GOD is a GOD OF LOVE. He is loving and forgiving.
May Trump's greatness be praised.
He build a tremendous company, very low debt. He could do it because GOD was merciful with him.
Trump is like the mustard seed, his supporters are like the ever growing mustard.
802.11 already does this a little bit with it's "listen before talk" mode of operation. It works, but there is only so much it can do with so many competing devices. Maybe someone can make it more efficient, but any gains in efficiency will surely be lost when even more devices try to use the same finite spectrum.
Some radios use GPS timing to make sure they all take turns, but that only works if all radios are pre-programmed to cooperate with each other in this manner. Even GPS timing across different manufacturers isn't compatible. I doubt we could ever get all radio manufacturers to agree upon and implement one common standard, so that idea is out.
Wireless is a classic case of cramming 10 pounds of shit into a 5 pound bag. Improvements can be made on the margins, but eventually you're going to need a bigger bag to make any real progress.
The key technology we need to unlock massive amounts of radio spectrum is directional radio links. Then you can have thousands of devices talking on the same frequency at the same time in the same area, without any interference. It's like how you can have dozens of billboards along the highway, without drowning each other out. You just look at the signal source you want to hear and ignore the rest.

Use doppler shift of signals, the ones that have have a measurable shift are the ones moving away, so use their slot since they'll probably leave the area soon.
without having to pay for the research. I am getting the feeling lately that the government is slowly getting left out in the cold.

Your mauther's a slot.
Not a machine learning issue. Software defined radios would probably open up most bandwidth all the time, if a central traffic control could coordinate the interactions. Another SINCGARS reference.
They moved to directed energy so each device can share the same spectrum at the same time. DARPA invented the technology that allows it called phased arrays.

SPECTRUM? SPECTRE? THRUSH?
Pthhhhh. Amateurs.
We don't share bandwidth in KAOS (a Delaware Corporation).
We don't share any-ting!
So give me my lunch back, Starker!!

Many areas use whoever had the first claim to the local water supply for a given area as the basis for who gets that water. Not what does the greatest good, not what makes the most economic sense, but merely the first to file. Then this right is locked in. The radio spectrum is similar however unlike water which is a local problem this causes problems for much of the globe. Think of the convenience of having most of the globe use 2.4GHz. Make a device once, use it anywhere. How grand. However things could be *much* better if more bandwidth was available globally. That's why I liken it to water rights - another archaic system but one that people more often understand. Here's a chart that shows how spectrum is allocated in the US for those who are curious: https://www.ntia.doc.gov/files...
Right now they just jam everything with their radio beams.
Are they intending to politely ask devices to get out of the way when they remote hack??
But the rest of the world and considering illegal frequencies being used around the US will make this problem harder than one thinks.
So you come up with a great solution for 900Mhz, problem is you can't use it in the EU or Asia. Or how about 433? nope, more conflicts outside the US.
Then there's the 1W vs 25mW (rest of the world) requirement....
Not only is this a tech and regulation problem, it's a frequency management and standards nightmare.
At least you can drive a DARPA challenge car or a biped robot in pretty much any country without conflicting tech (but conflicting regs).
I can't wait to watch this competition unfold live on YouTube!
I think your computer was "hacked" by weev...

Nothing new here. George Gilder was writing on this topic back in the mid-1990s. Bandwidth, he said, would become plentiful.

I already have this technology but I'm not going to provide it for 2 million. It's worth at least a thousand times that amount.

I've never seen that figure-of-speech before, so on my first read I expected it to end with "..but eventually you'll still have nothing but a load of shit."
