DNXA-93: 802.11n b/g wifi 2x2 PCIe half-size mini card, HB93/AR9283

DNXA-93 is a 802.11n b/g 2T2R in the smallest PCIe half-size form factor using AR9283 single-chip solution which leverages the 802.11n 2–stream specification to provide the optimal balance of performance and price from legacy 802.11 solutions. The two-stream feature enables a new class of WiFi devices that deliver performance enhancements over one-stream technology at comparable price point.
Setting new standards in throughput, range, reliability, and power consumption, DNXA-93 is capable to deliver the ultimate wireless triple play experience for video, voice, and data transmission in the home, for the business, and on the road.
Additionally, DNXA-93 features Atheros’ innovative system-level power-savings protocols, algorithms, circuit design techniques, and Wake-on-Wireless LAN to provide the highest level of 802.11n WLAN throughput and allows devices to remain lowest power consumption to extend battery life.
