Simultaneous Radio Xmit/Receive, on the SAME Frequency

from the stop-interrupting-me dept.

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"...

    So this could be a solution for people who are "transmit only" ?
