IEEE recommendations for Wi-Fi coexistence

The IEEE 802.15.2 standard recommends Packet Traffic Arbitration (PTA)-based architecture for coexistence between Wi-Fi® and Bluetooth® technologies.

The IEEE standard recommends a centralized coexistence logic that accepts prioritized transmit and receive requests from Wi-Fi and Bluetooth devices. The logic then determines whose request is granted to ensure fair allocation amongst the two. The Nordic coexistence design follows this approach and is enhanced with proprietary algorithms and software that mitigate different coexistence scenarios.
