MS Researchers Develop Acoustic Data Transfer System For Phones
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."
GREETINGS PROFESSOR FALKEN.
You can already transfer music between phones like this, but it's quite lossy depending on the quality of your speaker.
It's a keming problem.
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.
I think you mean: That's a wooshing problern.
