DNXA-92: 802.11n a/b/g wifi 2x2 PCIe half-size mini card, HB92/AR9280

DNXA-92 is a 802.11n a/b/g in the smallest PCIe half-size 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. 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.

Additionally, DNXA-92 features Atheros’ innovative system-level power-savings protocols, algorithms and circuit design techniques which include Dynamic MIMO Power Save (DMPS), Unscheduled Automatic Power Save Delivery (UAPSD), and Atheros Wake-on-Wireless to provide the highest level of 802.11n WLAN throughput and allows devices to remain lowest power consumption to extend battery life.

 

Key Features

  • The smallest PCIe form factor in 2Tx/2Rx design is ideal for embedding into ultra-compact devices or embed additional mini cards with complimentary technologies.
  • Windows 2000/XP/Vista/7 and ath9k drivers enable manufacturers to quickly and easily bring new bandwidth intensive applications to market with trouble-free WiFi integration.
  • 802.11n compliance effectively interoperates with other chipsets.
  • Seamless roaming cross 802.11n, 802.11a, 802.11b, and 802.11g in Access Point covered distance.
  • Enables bandwidth of up to 300Mbps link rate, six times the throughput of 802.11a and 802.11g.
  • Supports IEEE 802.11a/802.11b/802.11g backward compatibility allowing inter-operability among multiple wifi networks.
  • Dynamic MIMO Power Save (DMPS) conserves total system power by seamlessly downshifting to 1x1 MIMO operation when small amounts of data need to be transmitted or received.
  • Unscheduled Automatic Power Save Delivery (UAPSD) increases a device sleep time while transmitting real-time, moderate bandwidth traffic.
  • Atheros Wake-on-Wireless allows the host system to go into very low-power standby mode, but be awakened at any time by the network, or a remote device.
  • XSPAN™ with Signal-Sustain Technology (SST) 2Tx/2Rx design architecture optimizes for higher and greater reliable throughputs over range.
  • Supports 802.11x authentication, WPA, WEP-64, WEP-128, WEP-152 and 128-bit AES/TKIP encryption.
  • Two Hirose U.FL antenna connectors enable transmit and receive diversity for flexible 2x2 RF design.
  • RoHS 2002/95/EC compliance meets environment-friendly requirement.
