For 17 years, I've been writing about the possibilities of "cognitive radio", in which radios sense which spectrum is available from moment to moment and collaborate to frequency-hop (and perform other tricks) to maximize the efficiency of wireless communications.

TRAQ is a senior project from a group of Northeastern University engineering students; it's a quadcopter that seeks out and homes in on radio signals. As they write, "The quadcopter's potential applications include disaster relief, surveillance, search-and-rescue, and stolen goods recovery."
I'm interested in the technology as a way to get cameras automatically directed to hotspots in places like Gezi Park -- the drones could automatically focus on police based on their emergency radios, ensuring that the cops were always in shot.

Elliot Noss sez,
I thought you'd be interested in something we are helping with at SXSW this weekend. a group of folks are taking advantage of unlicensed radio spectrum to provide high-speed backhaul to local WiFi access points all over SXSW. In Austin, there are 14 of these open channels using whitespace that are available. we are leveraging this. on Tuesday, the FCC will close comments on its plan to auction off many of these "whitespaces. the 'We Heart Wifi' initiative is collecting signatures on the following petition. Even if folks aren't at SXSW, they can sign on:
To all FCC Commissioners:
Please follow through on your proposal to open up a large slice of high-quality spectrum for open networks. Doing so would help create the competition necessary to extend more high-speed broadband—including 'super WiFi' and other future innovations—to more people."
