DNXA-95: 802.11n b/g wifi 1x1 PCIe half-size mini card, HB95/AR9285

DNXA-95 is a 802.11n b/g 1T1R in the smallest PCIe half-size form factor using AR9285 single-chip solution features Atheros Align™ technology which leverages the 802.11n 1–stream specification to provide the optimal upgrade path from legacy 802.11 solutions. The single-stream feature enables a new class of WiFi devices that deliver performance enhancements over the existing 802.11g technology at comparable price points. DNXA-95 is forward compatible to higher-performance, multi-stream and MIMO–based 802.11n to serve the networking, PC and consumer electronics markets with optimal balance of performance and price. The enhanced throughput of DNXA-95 1–stream solution improves network efficiency by occupying the wireless channel for shorter periods than slower 802.11g devices – reducing congestion and increasing capacity for additional wireless devices. DNXA-95 employs all the mandatory and select optional features of the 11n specification, and Unex’s advanced radio design techniques to effectively double the wireless coverage over legacy WLAN.
