Universal embedded WLAN solution for OEM customers

WiBear-SF - Industrial universal WLAN front end module (IEEE 802.11b/g)

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

The WiBear-SF WLAN module features the following key b en efits:

• Extremely small and efficient footprint which covers 20 x 2 0 mm of size

• Simultaneous use of two different leading wir eless standards, the IEEE 802.11b, g WLAN and a full

featured Bluetooth IEEE802.15.1 class 2 transceiver.

• Micro Access Point feature for building WLAN n etworks with the maximum number of 8 clients

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

• Deploy the processor of the existi ng design as host controller: The WLAN- SF module is conne cted to the customer processor
by SDIO or G-SPI interfaces. The WLAN stack will run on processor of the existing design.

• Add the WiBear-SF WLAN module together with a host controller to an existing d esign. As an example, the host controller may
be a based on ARM9 core. A correspondin g reference design is available on request.

The host controller selection can consider additional needed interfaces like Ethernet, USB, CAN, or UART. The WiBear-SF
WLAN module is designed for industrial solutions in order to connect with already existing WLAN networks on shop floor.
Furthermore, an embedded Linux-based We b Server reference application is available to easily imp lement user-interfaces for
WLAN module configuration. The Bluetooth interface supports Bluetooth 2.1 and Enhanced Data Rate (EDR) operation. The
WiBear-SF complies with Bluetooth stacks that support SDIO or UART HCI protocol.

The WiBear-SF module is a compact one-side assemble d design and can be soldered (SMD) onto a customer boards. The
availability of the module is guaranteed for min imum of 6 years

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.
