MWC: Sound waves to connect devices

A new communication protocol allows any machines with speakers to connect to each other using sound

Ultrasonic communication company Sonarax has unveiled a new standard in machine-to-machine (m2m) connectivity, allowing devices to communicate with one another using sound waves. The protocol operates on any device that has a built-in speaker or microphone. It works even when the internet, GPS, and cellular networks are unavailable.

The protocol performs pairing between devices and transfer of data on both encrypted and open channels using sound waves. It provides significantly easier and faster deployments of m2m applications such as sonic QR codes, mobile payments, and ID authentication.

Sonarax’s protocol requires no special hardware and is easy to deploy and use. This protocol can be integrated with any application across various operating systems, including Windows, Android, and iOS, and is already embedded in leading sonic processors. Sonarax utilises frequencies beyond the threshold of human hearing and can be intertwined with any audio channel carried by media, including, TV, and others to introduce additional communication data, such as advertising information and more.

Sonarax’s ultrasonic technology was designed to provide initial solutions in three main important areas:

  • Ultrasonic Payments: Facilitating secure pairing for mobile payments and contactless ATM interaction – already in pilot with major global banks and financial institutions.
  • Ultrasonic Authentication: Providing a seamless and secure identification solution –  a fully developed and off-the-shelf SDK that can be easily integrated and used by any third party application
  • Ultrasonic Indoor Positioning: Allowing indoor positioning in buildings such as shopping malls and hospitals where GPS stops working. Sonarax is working to implement its technology for novel indoor navigation functionality to be launched at a later date.

Benny Saban, CEO of Sonarax, said: “We’re utilising the existing element of sound to modernise machine-to-machine connectivity so that it enhances payment authentication and for the first time can also be used for indoor positioning. Sound cannot fail or be compromised and we’re excited to finally reveal our product at MWC and get consumers onboard to the next generation of device communication.”
