DNXA-92: 802.11n a/b/g wifi PCIe half-mini card, HB92/AR9280

DNXA-92 is a 802.11n a/b/g in the smallest PCIe half-mini card form factor providing notebook or application specific device (ASD) manufacturers enhanced design flexibility to develop ultra-compact devices with optimal balance of performance and power consumption through Dynamic MIMO Power Save which conserves total system power by seamlessly downshifting from 2x2 MIMO to 1x1 MIMO operation when small amounts of data need to be transmitted or received.

 

With DNXA-92 dual-band design, consumers can enjoy universal connectivity to any 802.11 network. The 2.4GHz band readily performs less demanding data applications, and the virtually interference-free 5GHz band supports high-bandwidth, latency-sensitive applications like HD-quality video streams and wireless VoIP. Setting new standards in throughput, range, reliability, and power consumption, DNXA-92 delivers the ultimate wireless triple play experience for video, voice, and data transmission in the home, for the business, and on the road.

 

Key Features
