Derivint’s Broadcast Audio Coexistence System
Derivint’s Broadcast Audio Coexistence System provides one device to share music across multiple headsets
Next-generation devices increasingly require high-quality audio streaming without the constraints of traditional Bluetooth pairing. Broadcast audio allows a device to transmit audio streams that multiple receivers can tune into-ideal for AR/VR systems, smart glasses, and public audio sharing. However, the clients face three critical challenges:
No retransmissions
Broadcast audio is extremely sensitive to packet loss because no retransmissions are allowed.
No default antenna sharing
Maintaining stable, glitch-free broadcast audio required precise scheduling, prioritization, and antenna-sharing mechanisms not supported by default.
This made it difficult for the client to deliver a reliable broadcast audio experience in environments with heavy Wi-Fi activity. We implemented a complete Bluetooth Broadcast Audio system optimized to operate seamlessly even when WLAN is active, ensuring stable and high-quality streaming.
