MS Researchers Develop Acoustic Data Transfer System For Phones

Posted by timothy on from the just-do-it-quietly-ok dept.

angry tapir writes "Smartphones that support NFC have been making their way onto the market, but many handsets still don't support the wireless technology. As an alternative, Microsoft researchers have prototyped a system that instead uses a phone's microphone and speaker to transmit and receive data. The P2P data transfer system uses a novel technique of 'self-jamming' to stop nefarious third parties from monitoring transfers, and the researchers believe it's more secure than standard NFC communications. No word on whether it sounds like the squeal of a 56k modem."

      When I hear acoustic couplers I pound on the wall so they know to keep it down.

    You can already transfer music between phones like this, but it's quite lossy depending on the quality of your speaker.

    It's almost like they're modulating a signal and then demodulating it. I wonder if there's a name for this sort of thing.

      Well, clearly you'd want to come up with a name that combines the traits of modulating the signal and then demodulating it on the receiving end. I'll suggest... oh... the sigulator.
