We used the iperf utility to measure wireless network performance.
Note that this speed tests have 2~3 times of over head due to the double-layer network as below picture.
So the real speed should be 2~3 times faster in the general usage case.

Test envierenmant

  • Server - x86 HOST PC
  • Client - ODROID Boards
  • Test utility - iperf
  • Wireless router(AP) - ipTIME N804
