OEM USB WiFi Modules - WiFiHU
- 802.11 b/g/n compliant






The Radicom Research WiFiHU series is a secure WiFi module that easily adds WiFi connectivity to virtually any processor-based device.  The module is IEEE802.11 b/g/n compatible with a USB2.0 interface.  With reliable transmissions, this USB wireless device can achieve over-the-air data throughput of up to 150Mbps downstream PHY rates. 

The WiFiHU protects the host with WEP/WPA/WPA2 compliant security protocols.  The module is power efficient.

There are two models available, WiFiHU-a and WiFiHU-c. The WiFiHU-a has Dual Chip Antenna built-in eliminating the need for costly and time-consuming RF development and shortens time to market. The WiFiHU-c has two U.FL connectors for attaching antenna cables and antennas allowing flexibility to place antennas at desired locations.


  • Designed to meet IEEE802.11 b/g/n Ethernet standards
  • USB 2.0 hot swappable interface
  • Compatible with USB1.1 and USB2.0 host controllers
  • Small size: 1.0 x 1.1 x 0.25(H)
  • Operates in 2.4GHz frequency bands
  • Fast receiver Automatic Gain Control (AGC)
  • 300Mbps receive rate and 150Mbps transmit rate using 40MHz bandwidth
  • 150Mbps receive rate and 75Mbps transmit rate using 20MHz bandwidth
  • Wi-Fi security using WEP, WPA and WPA2
  • LED driver output for visual monitoring of link and activity 
  • Windows 2K, XP, Vista, Win7 support
  • Linux 2.4/2.6 support
  • RoHS compliant
  • Agency approvals:

    • FCC,IC & CE certified
