====== WIFI Module #3, #4 ======

===== WIFI Modules Test with ODROID Series =====
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
