The most used smart set-top box in home driven by the Android OS and based on Wi-Fi technology has to ensure nothing wrong with the Wi-Fi service regardless of the various user's installation environment. The direction test method about the nondirectional of the Wi-Fi doesn't be determined as the standard and each manufacturers devise the their own test methods and conduct the tests. In this paper, we created the 720 test cases considering 2 components of upload & download, the 10 elements of the vertical angle and the 36 elements of the horizontal angle looking at the wireless router in order to verify omni-directional Wi-Fi capability. In reality, from viewpoint in terms of cost and time constraint, it is difficult to test all the test cases. Therefore, we decided to reduce test cases by applying Pair-wise testing technique which is one of combinational testing techniques based on ISO / IEC 29119-4. And we obtained the test cases in which the Pair-wise technique was applied by Allpairs tool which output test cases automatically and conducted the test. It could be confirmed that the proposed technique shortened 48.61% of the time to be spent in progressing the existing test cases and that the trace about the part in which the problem was generated with the result of the simplified test case was possible enough.
