Coexistence Overview for AW611/IW611
Overview of Wi-Fi and Bluetooth coexistence for NXP AW611/IW611, detailing real-time arbitration via the Packet Traffic Arbiter (PTA) and interference avoidance mechanisms.
Overview
This application note provides a technical overview of the coexistence architecture between Wi-Fi and Bluetooth/BLE radios in NXP AW611 and IW611 combo wireless devices. The solution utilizes three primary components: a central hardware Packet Traffic Arbiter (PTA) for per-packet arbitration, a local hardware arbiter for BT/BLE traffic, and coexistence software for configuration. The document explains interference avoidance through coordination of the Adaptive Frequency Hopping (AFH) map and describes the request/grant mechanism used to manage radio access. It also details traffic prioritization based on packet type and profile, as well as antenna configurations for both shared antenna (via RF switch) and dedicated antenna applications.
Use Cases
- Designing wireless combo devices with simultaneous Wi-Fi and Bluetooth connectivity
- Implementing interference mitigation in IoT devices using NXP AW611/IW611
- Configuring RF front-end antenna sharing between Wi-Fi and Bluetooth radios
- Optimizing wireless traffic priority and latency in multi-radio systems
