The SX-SDWAG is the world's first 802.11a/b/g WLAN module in an SDIO card form factor. With a minimum sleep mode power consumption of just 3mA, the SX-SDWAG is ideal for battery-operated portable devices in wireless local area network (WLAN) applications in the medical, weights and measures, transportation and other industries.
Unlike WLAN SDIO cards that are intended for use in PDAs, the SX-SDWAG
is specifically aimed at OEM applications. It includes diversity
antenna connectors for improved radio reception and flexibility in
antenna selection, and it supports an extended temperature range of -40
to +70 degrees C. The SX-SDWAG’s 802.11a 5GHz capabilities allow it to
be used in enterprise environments such as hospitals, where
interference from 2.4GHz devices like microwave ovens must be
minimized. Silex also offers driver porting and consulting services for
Linux, Windows CE, and other operating systems, as well as custom
hardware design capabilities.
Measuring just 0.94 x 1.68 x 0.08 inches (24 x 42.7 x 2.1mm), the
SX-SDWAG is slightly longer than a standard SD memory card. Because it
has a standard SDIO form factor, OEMs can use off-the-shelf SDIO
mounting hardware and test equipment to expedite the development
process.
The SX-SDWAG implements half-duplex OFDM, CCK and DSSS base-band processing supporting all IEEE 802.11a/b/g data rates. The MAC supports the IEEE 802.11 wireless MAC protocol as well as 802.11i security, receive and transmit filtering, error recovery, and quality of service (QoS).

Custom Driver Development
Because of the many hardware and software variables (for example, processor type, I/O controller, operating system version, etc.) there is no "one size fits all" driver for the SX-SDWAG. As a result, SIlex offers custom programming services to port our drivers to your hardware platform. We have significant experience with Linux, Windows CE, VxWorks, pSOS, ITRON, and other real-time operating systems, so we can get the job done quickly and efficiently.
