Introduction
The WiBear11n industrial universal module is targeted
for integration into different OEM products. The module
is designed for both simultaneous and independent
operation of the following:
IEEE 802.11a/b/g/n payload data rates for Wireless
Local Area Network (WLAN), Bluetooth 3.0+High
Speed (HS) and Bluetooth 2.1+EDR.
It provides a complete end-to-end solution for lowpower applications. It includes an integrated
MAC/Baseband processor and RF front-end
components and can connect to a host processor
through an SDIO interface.
The WiBear11n modules are offered in four versions
(see ordering information and block diagram).
Host drivers for common operating systems such as
Linux and Windows 7 are available.
The modules are radio type approved for Europe (CE),
US (FCC) and Industry Canada (IC) (pending).

Model Description
WiBear11n-SF1 Single band WLAN (802.11 b/g/n, 2.4 GHz only) and Bluetooth module. Module has one
joint antenna connector for WLAN and Bluetooth operation (see block diagram).
WiBear11n-SF1/-DF1 is recommended for cost effective AP solution, AP without or rare
Bluetooth traffic or cost effective station with one system antenna.
WiBear11n-SF2 Single band WLAN (802.11 b/g/n, 2.5 GHz only) and Bluetooth module. Module has
separated antenna connectors for WLAN and Bluetooth operation (see block diagram).
Overall performance (throughput) is maximized for AP mode with simultaneous Bluetooth
traffic. Two system antennas are required (one for WLAN and one for Bluetooth) with 30
dB or better isolation between antennas (orthogonal oriented antennas with more than
50…60 mm. distance between). May be recommended for higher performance of AP.
WiBear11n-DF1 Dual band WLAN (802.11 a/b/g/n, 2.5 and 5 GHz) and Bluetooth module with one joint
antenna connector for WLAN and Bluetooth. Similar to WiBear11n-SF1.
WiBear11n-DF2 Dual band WLAN (802.11 a/b/g/n, 2.5 and 5 GHz) and Bluetooth module which has
separated antenna connectors for WLAN and Bluetooth. Similar to WiBear11n-SF2.
Note: For maximum throughput during simultaneous WLAN (AP) and Bluetooth operation, the Bluetooth
Coexistence Arbiter (BCA) settings should be optimized by the host system software.
