WiBear - Industrial universal WLAN front end modules

Subject to technical modifications!

April 2010

(IEEE 802.11a/b/g)

The lesswire industrial universal WiBear WLAN module is a reliable, automotive grade WLAN front end
module. The module is developed for use in industrial temperature range from -40°C to +85°C.

The WiBear WLAN modules feature two key benefits:

• Two WiBear-versions are available for the communication in the 2.4GHz (WiBear/2.4GHz) and in
both 2.4 + 5 GHz (WiBear/5GHz) frequ ency bands. The WiBear/5GHz module allows to use addi­tional 19 channels in the 5 GHz band outside the 2.4 GHz band, w hich often is cr owded by other 2. 4
GHz devices.

• Offers the simultaneous use of two different leadin g wireless standard s, the IEEE 802.11a/ b,g WLAN
and a full featured Bluetooth IEEE802.15.1 Class 2 tr ansceiver.

The WiBear WLAN module may be integrated in two ways into customer solutions:

• Deploy the processor of the existing desig n as host contr oller: The WLA N module is conn ected to the
customer processor by SDIO or G-SPI interfaces. The WLAN stack will run on processor of t he exist­ing design.

• Add the WiBear WLAN module together with a host contr oller to an existing design. As an example,
the host controller may be a based on ARM9 core.

The host controller selection can consider a dditional needed interfaces like Ethernet, USB, CAN, or UART.
The WiBear WLAN module is desi gned amongst others for industrial so lutions in order to connect with already existing WLAN

networks on shop floor. Furthermore, an embedded Linux-based Web Server reference application is available to easily
implement user-interfaces for WLAN module configuration.

The universal WLAN module saves time and reduces costs. OEM customers can concentrate on their core competence while
adopting this easy to use WLAN module that can ena ble many w irel ess applicati ons. For larg er quantity orders les swir e can als o
provide module design-ins. Driver porting to other operating systems can be offer ed by lesswire.
