DSP Concepts and delResearch Deliver Data over Sound
In a collaboration between DSP Concepts and delResearch, the new AirModem data-over-sound technology is available on the Audio Weaver platform. AirModem functions much like a sound-based QR code, enabling IoT device provisioning, proximity detection, two-way acoustic near-field communication (NFC) and telemetry. This technology boasts reliable communication performance in RF-restricted environments, using low-power microcontroller units and Arm Cortex processors.
