    If only radio wave bandwidth couold be used for wifi for consumers, instead of law enforcement, etc.
    I don't understand why they need it, their system works pretty well as it as, as far as I can tell.

    Leave it to the Italians to achieve a wireless breakthrough modeled after a noodle :) In all seriousness, I've been hearing about this kind of research for well over a year and figured it wouldn't be too long before it was engineered into reality. I expect we'll be seeing rollouts of this tech inside of two years - the cell carriers will be racing to develop their own versions of it. A shame they'll probably only use it to create 6G radios instead of actually expanding their network capacity.

    This is fascinating! Nice find. Also "lulz" @ psycros' first sentence.

    I wonder if it takes completely different equipment or if current WiFi equipment can do it with a software update....
