2 Product Overview
Wi-Fi and Bluetooth Radio Module
The PAN9026 is a dual band 2.4/5 GHz 802.11 a/b/g/n Wi-Fi radio module with integrated
Bluetooth BDR/EDR/LE, specifically designed for highly integrated and cost-effective
applications. The simultaneous and independent operation of the two standards enables high
data rates (802.11n) and low-power operation (Bluetooth Low Energy). Integrated power
management, a fast dual-core CPU, 802.11i security standard support, and high-speed data
interfaces deliver the performance for the speed, reliability, and quality requirements of next
generation products. TX power calibration data and Wi-Fi/Bluetooth system parameters are pre-
stored on the one-time-programmable memory of the PAN9026 during production at Panasonic.
This simplifies passing the certification process for PAN9026 customers. Furthermore, the
module reduces design, test, and calibration effort resulting in reduced time-to-market
compared to discrete solutions.
Integrating Wi-Fi and Bluetooth wireless connectivity allows applications such as Smart Energy
and home gateways to manage multiple devices and appliances. The combination of Wi-Fi and
Bluetooth provides the highest flexibility for connectivity.

2.7 Coexistence
The implemented coexistence framework is based on the IEEE 802.15.2 recommended practice
Packet Traffic Arbitration (PTA) scheme and the Bluetooth Special Interest Group (BTSIG) Core
Specification Volume 7 (Wireless Coexistence Volume).
2.7.1 WLAN/Bluetooth Channel Information Exchange
Since Bluetooth and IEEE 802.11b/g/n WLAN use the same 2.4 GHz frequency band, each can
cause interference with another. The level of interference depends on the respective frequency
channel used by Bluetooth and WLAN (other factors can impact interference, like Tx power and
Rx sensitivity of the device).
In a system with both Bluetooth and WLAN, the common host receives information about WLAN
channel usage and passes the information to the Bluetooth device. For Bluetooth 1.2 devices
with Adaptive Frequency Hopping (AFH) enabled, the Bluetooth device can block channel
usage that overlaps the WLAN channel in use.
When the Bluetooth device avoids all channels used by the WLAN, the impact of interference is
reduced, but not completely eliminated. For Bluetooth 1.1 devices, the Bluetooth device cannot
block WLAN channel usage. In this case, a Bluetooth Coexistence Arbiter (BCA) scheme at
MAC level is required. The BCA scheme can also be used with Bluetooth 1.2 devices to further
reduce the impact of interference to a minimum.
2.7.2 External Mobile Wireless System (LTE/ZigBee) and BCA Exchange
Based on the BTSIG Wireless Coexistence Volume, the device supports a Wireless
Coexistence Interface 2 (WCI-2) protocol for WLAN/Bluetooth coexistence with an external
Mobile Wireless System (MWS), such as a Long Term Evolution (LTE) or ZigBee device.
WCI-2 is a 2-wire transport interface. An internal coexistence is used to exchange request/grant
with the BCA.

2.7.4 WCI-2 Interface
The coexistence interface includes a Mobile Wireless System (MWS) transport controller to
accommodate a 2-wire, UART-based serial transport interface. This interface is a standard full-
duplex UART (TXD and RXD) carrying logical signals framed as UART characters. In addition, it
allows support of multiple logical channels.

RESEND_REAL_TIME
This bit is set if a device wants to get a status update of the real-time signals.
The signal is usually used after wake-up from sleep of the transport interface
to get an update of the real-time signals.
If the receiving device’s transport interface is awake it shall send a real-time
message with the current status of the real-time signals within 4 UART
character period. If the signal is not transmitted within 4 UART character
periods, the device is considered asleep.
If the receiving device’s transport interface is not awake it shall not send a
real-time message.
Bluetooth initiated:
If the MWS is currently scanning or has an ongoing inactivity duration, the
MWS shall send a frequency scan message or an inactivity duration message
after transmitting the real-time message.
If the receiving device’s transport interface is not awake it shall not send a
frequency scan or inactivity duration message.
