RAW USB data over IP even through WiFi
protocol based on USB with is own device driver both on windows and linux and with a medium transfer rate (about 50% of USB2 specification ~200Mbit/s).


That would be very hard to acieve on a wifi link. Most WiFi equipment ships with a 100MBps Ethernet port, even 300MBit Wifi cannot saturate it. 


  My idea is to build something like a "repeater" using two Arduino as Source and destination


Arduino only supports 12 MBit/s USB Full speed. If your original data rate estimate is correct, you need beefier equipment that actually supports USB2.0 High Speed.
