Tech Review reports an "impossible" development, https://www.technologyreview.com/lists/innovators-under-35/2016/inventor/dinesh-bharadia/

Because the signal from broadcasting a radio transmission can be 100 billion times louder than the receiving one, it was always assumed that outgoing signals would invariably drown out incoming ones. That's why radios typically send and receive on different frequencies or rapidly alternate between transmitting and receiving. "Even textbooks kind of assumed it was impossible," Bharadia says.

Bharadia developed hardware and software that selectively cancel the far louder outgoing transmission so that a radio can decipher the incoming message. The creation of the first full-duplex radio, which eventually could be incorporated into cell phones, should effectively double available wireless bandwidth by simply using it twice.

Any bets on when this will make it to production, maybe as part of 7G(eneration) wireless? Or will the technology go black, used first by military?

And, does a person's name ever influence their career? "Bharadia" sounds awfully close to "bi-radio"...

    I realize a bunch of 9s doesn't necessarily mean much to a lot of people, so let me give a more concrete example:
    The moon is 238,900 miles away. Being able to eliminate that much noise is akin to being able to map, from here, the height of the moons surface with 1/8" accuracy

    Or alternately, to be able to stand in LA, and measure the thickness of a single strand of hair in New York

    And for those MBAs you could just say it's 12σ, that's 2 times more 9's than with [wikipedia.org]!

        I was referring to the amount of nines.
