WHY DON'T HIGH SCHOOLS TEACH, OWN, AND RUN HAM RADIOS !!!
DARPA's latest grand challenge takes on the radio spectrum
By David Szondy Mar 27 2016
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 aimed at alleviating an ongoing technological headache. Ever since the invention of radio, it's been recognized that there is only so much of the electromagnetic spectrum to go around, so government regulations were imposed to allocate bandwidth.
Early broadcast technology was fairly crude and radio and television services, for example, were given whole regions of the spectrum that today seem like allocating the entire Missouri river basin to run a toothpick factory. In recent decades, the rise of digital technology has pushed a reshuffle of these allocations that has also sparked a lot of bickering in military and civilian circles over who gets what and how much.
The 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 US$2 million.
To host the event and act as a venue for further research, DARPA is building the largest-of-its-kind wireless testbed called the "Colosseum" after the famous arena in Rome. This will allow researchers to carry out large scale tests in a controlled environment that can be configured to simulate real-world problems.
"DARPA Challenges have traditionally rewarded teams that dominate their competitors, but when it comes to making the most of the electromagnetic spectrum, the team that shares most intelligently is going to win," says SC2 program manager Paul Tilghman of DARPA's Microsystems Technology Office (MTO). "We want to radically accelerate the development of machine-learning technologies and strategies that will allow on-the-fly sharing of spectrum at machine timescales."
DARPA will release a Broad Agency Announcement for SC2 in the near future. In addition, there is
a website for the latest information on the challenge.
Spectrum Radio Community Networking
Our Hero Dave Hughes
Founder of Old Colorado City Communications
Read About The Electronic Public Interest Versus the Private Good - Spread - Spectrum Radio
Dave Hughes is probably the premier technical and policy facilitator in grass-roots community networking. In 1981, he started what may be the first bulletin board system (BBS) whose goal was to empower the local public politically. Since then, Hughes has traveled around the world in an effort to bring some of the most disenfranchised and isolated communities into the electronic age.
In Hughes's home town, Colorado Springs, Colorado, all residents can get online, including truck drivers logging in from Rogers Bar. On more than one occasion, Colorado Springs citizens organized by Hughes online won a changes in the procurement policy by local government. His local private bulletin board has evolved into a city-run "City Link" on which the city council communicates openly with the entire community online. Hughes is targeting the state legislature next.
Hughes Delivers Universal Net Access
"I told my sons to bury me in a grave with space enough for an Internet connection so I can come back and keep giving 'em hell."
Dave Hughes has definite tastes. What he likes: Stetson hats, Justin Boots, turquoise-studded bolo ties, and universal Internet access. What he hates: fools, bureaucrats, and phone companies. And the way the trailblazing activist figures it, Washington, DC, is where the fools and the bureaucrats conspire to make things easier for the phone companies to prevent truly universal Net service. "Fifty percent of Washington is full of conspiracists," he says. "The other 50 percent runs on the great American tradition of pure incompetence."

FCC'S HATFIELD TELLS HAMS TO "WALK THE WALK"
From: Gary Johnston <email@example.com>
To: Dave Farber
The FCC's Dale Hatfield, W0IFO, predicts a bright future for Amateur Radio. But the Office of
and Technology chief says that amateurs "will be under a certain amount of pressure" to justify
their free use of the radio spectrum. As a result, he said, it will be more important than ever that hams
actually fulfill their service, good will and educational roles--not just talk about them.
Hatfield offered his observations as keynote speaker for AMRAD's 25th anniversary dinner June 17 in Virginia. Hatfield told the gathering, "the key issue for the amateur service is maintaining access to an adequate amount of spectrum." While emphasizing that he was not suggesting any immediate threat, Hatfield said hams will have to do a better job of justifying their current allocations.
Hatfield said hams should actually engage in experimentation to advance the state-of-the-art, provide communication and train operators for emergencies, encourage international cooperation and good will, and offer an important technical educational outlet. "Or, to use a bit of slang, it seems to me that it will be even more important for all segments of the amateur community to 'walk the walk' not just 'talk the talk'," he said.
Hatfield encouraged his audience to explore advanced techniques that conserve spectrum, especially digital techniques. As the rest of the telecommunications world transitions to digital techniques, Hatfield said, "the amateur service will look antiquated if it is not making progress in that direction as well."
Hatfield also said software defined radios could facilitate "a new era of amateur experimentation" and, in many ways, represent "a final merger" of radio communications and computers.
