Our Technology

Thanks to our patent-pending technology, audio-based beacons have finally become a reality.

The key to our SonBeacon technology is the audio signal that was developed together with the Fraunhofer Institute for Secure Information Technology.

  • The SonoBeacon technology uses audio frequencies (20 to 22 kHz) in which the information is modulated. The audio signal is inaudible for the human ear.
  • The audio signal is transmitted by a conventional speaker.
  • A microphone receives the audio signal and detects the audio signal.
  • The detection of the signal is executed within a single device i.e. a smartphone. An internet connection is only necessary for requesting the content that needs to be displayed.
  • Based on the configuration, further actions can be triggered (i.e. the transmission of a shopping cart, context-sensitive content, coupons etc.)

Step 1: Create signal

The SonoBeacon technology generates a high-frequency signal ...


... which is transmitted by a new or existing speaker or audio source.

Step 2: Detect signal and trigger action

A SonoBeacon enabled app or website ...


... detects the high-frequency signal and triggers a configured action.

Based on our SonoBeacon technology, we are able to offer two different products that are best suited for all industries.
