Superior Performance with Longer Range

SparkLAN WPEA-121N WiFi PCI express card, embedded with Atheros AR9382 chipset, is incorporated with Atheros XSPAN with Signal Sustain Technology (SST). The 11n Daul-Band PCIe supports 2T2R (2-stream) MIMO technology, which delivers superior throughput up to 300Mbps and improves the overall WiFi coverage area. 

Ideal for High-End Notebook
The module adopts the latest 802.11n Dual-Band technology (2.4GHz and 5GHz). It targets enterprise and high-end consumer notebooks. The solution enables up to 6 times the throughput of 802.11a/g solutions. 

Industry-Leading Power Efficiency
WPEA-121N, featuring Atheros’ highest level of 802.11n WLAN throughput, enables a high performance, cost effective, low power, and compact solution for developers to easily integrate with embedded computing platforms.
