-A +A

DNUR-S2 is an 802.11n a/b/g wifi 2x2 MIMO USB module designed specifically for USB-equipped wireless embedded systems and consumer electronics that demand robust link quality and maximum throughput at range. Optimized RF architecture and production calibration, DNUR-S2 sets new standards in superior throughput performance at low power consumption to deliver the ultimate wireless triple play experience for video, voice, and data transmission in the home, for the business, and on the road.

Integrating the market-proof wifi design experiences and well-known production calibration system enable Unex’s customers to quickly and easily bring quality-consistency wifi-embedded systems to market.

  • 4.2cm x 2.5cm small dimension with 4-Pin USB 2.0 header is ideal for new ergonomic USB-equipped wireless embedded systems and consumer electronics.
  • 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.
  • SoftAP (Software enabled Access Point) support on Windows XP/Vista/7 provides peer-to-peer capability.
  • Optional SoftAP support on Linux valid by project request.
  • Wi-Fi Direct support on Windows XP/Vista/7 and Linux allows WiFi devices to connect to each other with no need for a wireless access point.
  • Optimized RF architecture and baseband algorithms provide superior performance with low power consumption. 
  • Intelligent MAC design deploys a highly efficient DMA engine and hardware data processing accelerators without overloading the host processor. 
  • 2.4/5 GHz dual band 2T2R supports a 300 Mbps PHY data rate and fully complies with 802.11a/b/g/n specifications.
  • Supports 64/128-bit WEP, WPA, and WPA2 advanced security.
  • Two Hirose U.FL antenna connectors support MIMO functionality. 
  • RoHS compliance meets environment-friendly requirement.
