The WLn-LINK-OEM embedded module is a 2.4 / 5 / 5.4 GHz IEEE 802.11n a/b/g/ solution designed to quickly and easily add wireless LAN to a wide range of wired Ethernet OEM products.

More than just a radio adaptor, the WLn-LINK-OEM features a fully integrated IEEE 802.11n a/b/g radio and a powerful Power PC processor that provides a complete wireless connection in a single small footprint. 

The WLn-LINK-OEM reduces the design time and eliminates the risk associated in wireless chipset based designs by providing all of the WiFi network protocols and processing needed to quickly implement embedded wireless solutions;  its industrial-grade performance makes it ideally suited for harsh environments.

Integrators and manufacturers (rugged computers & instruments, intrinsically safe wireless devices, remotely operated vehicles UAV/UGV/UUV, automotive, COTS-based data communication units for military applications...) can rely on this new technology to add wireless network features to their existing equipments.
