DARPA High Speed Wireless Program Aims For The Sky

By

The Defense Advanced Research Projects Agency (DARPA) is beginning work to develop a wireless communications system capable of transmitting data at speeds of 100 gigabits per second, rivaling high-speed fiber optic systems.

The technology is also intended to get around one of the biggest hurdles facing tactical military communications: the effects of weather degrading high-bandwidth transmissions between aircraft and ground stations and vehicles. Cloud cover is one of the big challenges facing high-bandwidth air-to-ground data communications, DARPA officials said. Keep reading →

The Case Of Shredded Documents: DARPA Draws Big Crowd To Solve A Puzzle

By

The Defense Advanced Research Projects Agency’s “Shredder Challenge” could be called the world’s ultimate jigsaw puzzle contest. But it was serious business for the nearly 9,000 teams of problem solvers from all over the world who entered the competition after DARPA officials launched it in late October.

In the Shredder Challenge competitors attempted to reconstruct machine-shredded documents in increasingly difficult stages to claim DARPA’s $50,000 prize. The challenge comprised five separate puzzles in which the number of documents, the content of the documents and the technique employed to shred the documents varied to make the challenge progressively more difficult.
