Reliable High-Speed Industrial Embedded Application
SparkLAN WPEA-127NI is a high-speed 802.11n pcie module based on Atheros XB114 Reference Design (AR9390-AL1B chipset), which delivers up to 450Mbps data rate. The PCI express module supports the high transmission data rate and reliable performance of 3x3 radios which are ideal for streaming multimedia applications. It provides 3-stream MIMO configurations, which is a suitable choice for wifi applications, such as high-end Wi-Fi applications (mesh network, wireless monitor, and high-end notebook and PC) or digital home networking equipment (access point, router, set-top box, and gateway), and video-over-wireless applications.

Industrial-Grade Temperature Range
WPEA-127NI is able to function under sever weather condition (-40 ~ 80°C), which is ideal for manufacturers to integrate with their devices that are designed for extended temperature range.
