A new cognitive radio demonstrates innovations that enable smarter use of wireless spectrum. This cognitive radio can sense and rapidly switch between the widest-ever range of frequencies, at record speeds, while sending the equivalent of 20 HD movies at once. With a rising tide of smart-phone data threatening to drown the airwaves, a White House advisory panel is poised to suggest that wireless carriers and research labs ramp up efforts to use computing to far more efficiently tap spectrum. This will require, among other things, so-called “cognitive” radios, which sense unused radio bands and can intelligently switch heavy data loads between different frequencies without any interruption.
