Preset if identical or both the difference of wireless performance value at wireless performance value and flex point that the test result obtains is less than
Threshold value, then using candidate's test benchmark point as test benchmark point；
If the wireless performance value difference at wireless performance value and flex point that the test result obtains is larger, constantly fine setting is wireless
The position of client, makes the wireless performance of wireless client current location and the wireless performance at flex point identical or very close,
The point using location point finally identical or very close with the wireless performance at flex point as test benchmark.
A kind of 10. antenna directivity test system as claimed in claim 7, it is characterised in that：The test output unit will
The wireless device to be measured increases angle according to fixed angle step-length and is rotated between 0-360 °, the test wireless device rotation to be measured
The wireless performance of each angle is gone to, after the wireless device to be measured completes the rotary test of 360 ° of omnidirectional, exports its antenna side
Tropism test result.
