The SDC-EC25N ExpressCard radio card from Laird Technologies 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 EC25N card. This dual-band radio module operates in both the 2.4 and 5 GHz frequency bands supporting IEEE 802.11n as well as 802.11a, 802.11b, and 802.11g. As a result, the SDC-EC25N module is ideal for integration into a vehicle-mounted mobile computer or any other business-critical mobile device that runs Windows XP or Windows 7.
The latest EN 300 328 standard (v.1.8.1) takes effect January 2015. Please see Laird's official statement on how to achieve compliance with this new standard.
