Just when you thought it was safe to go back in the water, of modem technology, Microsoft has developed a software modem that will have your mobile phone squealing like a 56k modem from decades past.
Developed by Microsoft Research Indian the Dhwani acoustic modem technology allows secure data transmission between all types of mobile phones. Requiring no new chipset or radio hardware the system sidesteps all current NFC (Near Field Communication) standards by simply using the microphone and speaker of the connecting phones. Allowing any phone with a speaker and a microphone to use the technology. Unfortunately the technology won’t talk with current NFC standards and isn’t a direct competitor at all as its only able to transmit small files at the moment.
To use the technology simply load the Dhwani software onto two phones and hold them in close proximity to initiate a file transfer. A modern take of the squealing modem noise will begin, ending once the file transfer is complete. Speeds are still limited with the technology capable of 2.4kbs, 20 times slower than a trusty old 56k modem.
