DNUA-93F is an 802.11n b/g wifi one-stream USB adapter designed specifically to provide enhanced WiFi performance and value for home gateways, set-top boxes, gaming consoles, printers, IP cameras, and variety of other products that host processors not originally intended to support WiFi functions. DNUA-93F's AR9271 single-chip features a new architecture that integrates both a CPU and memory to run more of the WiFi function on-chip. The integrated CPU offloads the wireless processing overhead from the host appliance and enables consumer electronic devices to support WiFi functions seamlessly without change of original host processors.

  • Integrated CPU and memory to run more of WiFi function on-chip to offload wireless processing overhead from the host appliance.

DUT & Driver Downlink Uplink
Utilization Throughput Utilization Throughput
AR9271 (v7.7.0.77) 36% 105.21Mbps 30% 105.95Mbps
Competitor (v1.4.7.0) 52% 83.24Mbps 30% 97.41Mb
  • Innovative embedded antenna design with perfect 3D radiation pattern enhances at least 15% better Tx power and Rx sensitivity performance than competitors.

3D Radiation Pattern at 2.4GHz

 

  • 30(L) x 17(W) x 8.5(H) mm small dimension with standard USB connector is ideal for new ergonomic home gateways, set-top boxes, gaming consoles, printers, IP cameras, and variety of other WiFi products that host processors not originally intended to support WiFi functions..
  • Windows XP/Vista/7, and Linux drivers enable manufacturers to quickly and easily bring new bandwidth intensive applications to market with trouble-free WiFi integration.
  • Supported by ath9k providing Linux kernel AP/Station/IBSS/Monitor-mode drivers for industrial, academic, or personal projects at highest flexibility and lowest cost.
  • 802.11n compliance effectively interoperates with other chipsets. 
  • Enables bandwidth of up to 150Mbps link rate, three times the throughput of 802.11g.
  • Supports IEEE 802.11b/802.11g backward compatibility allowing inter-operability among multiple wifi networks. 
  • Embedded antennas support one-stream 802.11n with Rx diversity. 
  • The only one-stream 802.11n solution with two embedded antennas supports WiFi diversity to better throughput over range.
  • RoHS compliance meets environment-friendly requirement.
