Amazing new wireless tech: Breaking Shannon's Law

Working in sensor networks we could really use one of these breakthrough technologies and in the past year or two I've heard at least three vendors give the exact same pitch but as of today there's no technical detail that gives me much hope.

Please tell me more about your magical energy-free signal propagation!

In all seriousness, Shannon's entropy limit only applies to a single variable, modulated at a certain frequency. The only reason we apply this limit to radio is because we treat each radio frequency in a given zone as a single variable. In fact, you're perfectly free to use directed antennas or interferometry to establish multiple communication variables on the same frequency.

Ah, and indeed, at 1:19, Perlman mentions each cell phone on a separate spatial domain.

Since they say it's a single cell phone antenna, I'm guessing we're looking at multiple towers and interferometry between them, possibly taking advantage of the intensity dropoff with distance and timing data for spatial discrimination.
