providing quality service and technical support in order to expedite the product 
development process. The WiFiHU2 Module requires only a USB (Universal Serial Bus) 
interface to add state of the art data WiFi wireless operation to any system. It is designed 
to fully support IEEE802.11n™ Draft 2.0, IEEE802.11e™ and IEEE802.11i™ 
standards. If further information is required, please contact us and we will provide any 
additional help needed. The WiFiHU2 series offers Soft AP support.  It can turn your 
Internet connected PC or Laptop into a WiFi Wireless Access Point.  So any WiFi devi
such as iPhone, iPod, PDA, within range can connect to Internet by sharing your 
WiFiHU2 Access Point.
