Hi,
Kindly provide you some info from the datasheet first.
5.7 Advanced Bluetooth/WLAN Coexistence
The CYW4356 includes advanced coexistence technologies that are only possible with a Bluetooth/WLAN integrated die solution.
These coexistence technologies are targeted at small form-factor platforms, such as cell phones and media players, including applications such as VoWLAN + SCO and Video-over-WLAN + High Fidelity BT Stereo.
Support is provided for platforms that share a single antenna between Bluetooth and WLAN. Dual-antenna applications are also supported. The CYW4356 radio architecture allows for lossless simultaneous Bluetooth and WLAN reception for shared antenna applications. This is possible only via an integrated solution (shared LNA and joint AGC algorithm). It has superior performance versus implementations that need to arbitrate between Bluetooth and WLAN reception.
The CYW4356 integrated solution enables MAC-layer signaling (firmware) and a greater degree of sharing via an enhanced coexistence interface. Information is exchanged between the Bluetooth and WLAN cores without host processor involvement.
The CYW4356 also supports Transmit Power Control on the STA together with standard Bluetooth TPC to limit mutual interference
and receiver desensitization. Preemption mechanisms are utilized to prevent AP transmissions from colliding with Bluetooth frames.
Improved channel classification techniques have been implemented in Bluetooth for faster and more accurate detection and elimination of interferers (including non-WLAN 2.4 GHz interference).
The Bluetooth AFH classification is also enhanced by the WLAN core’s channel information.
