Dual-Band N ExpressCard with Antenna Connector

The EC15N has reached end of production and is available on a limited basis only. 

The EC15N ExpressCard radio card from Laird combines a high-performance, dual band 802.11n radio with software, both designed for business-critical mobile devices that operate in harsh environments. No other Wi-Fi radio card can match the range, robust security, seamless mobility, and manageability of the EC15N card.
