PAN9026 Wi-Fi/BT Module
2 Overview
2.7.5 Bluetooth Coexistence Arbiter
Type
Capability
Arbitration
AFH
Features
Programmable coexistence interface timing, interface modes, and signal
polarity to support a variety of external Bluetooth devices
Programmable decision policies and transaction lock behavior for
various use cases
Interface with external or on-chip Bluetooth device
Support Bluetooth 1.1 or Bluetooth 1.2 AFH
WLAN-/Bluetooth-coordinated low-power design
Enhanced information sharing between WLAN and Bluetooth for combo
systems
WLAN/Bluetooth/MWS (LTE/ZigBee) coexistence support
Contention resolved by a customizable decision matrix that allows
independent grant decision for each device
Vectors for the decision matrix:
WLAN priority (2-bit)
WLAN direction
Bluetooth priority (1- or 2-bit)
Bluetooth direction
Bluetooth frequency in/out band
MWS priority (2-bit)
MWS direction
If AFH is enabled in the Bluetooth device, and there is a sufficient guard-
band outside the WLAN operating frequency, the Bluetooth device uses the
Out-Of-Band (OOB) channel with respect to the WLAN device. Otherwise,
the Bluetooth device uses the In-Band (IB) and OOB channels with respect
to the WLAN device.
The IB and OOB information is either provided by the Bluetooth device
through the coexistence interface, or it can be provided through firmware
controls in a shared-host system. IB/OOB is a vector in the decision matrix.
