Universal embedded WLAN solution for OEM customers
WiBear - Industrial universal WLAN front end modules
(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) frequency bands. The WiBear/5GHz module allows to use addi-
tional 19 channels in the 5 GHz band outside the 2.4 GHz band, which often is crowded by other 2.4
GHz devices.
• Offers the simultaneous use of two different leading wireless standards, the IEEE 802.11a/b,g WLAN
and a full featured Bluetooth IEEE802.15.1 Class 2 transceiver.
The WiBear WLAN module may be integrated in two ways into customer solutions:
• Deploy the processor of the existing design as host controller: The WLAN module is connected to the
customer processor by SDIO or G-SPI interfaces. The WLAN stack will run on processor of the exist-
ing design.
• Add the WiBear WLAN module together with a host controller to an existing design. As an example,
the host controller may be a based on ARM9 core.
The host controller selection can consider additional needed interfaces like Ethernet, USB, CAN, or UART.
The WiBear WLAN module is designed amongst others for industrial solutions 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 enable many wireless applications. For larger quantity orders lesswire can also
provide module design-ins. Driver porting to other operating systems can be offered by lesswire.
