The following detailed description of the invention refers to the accompanying drawings, which illustrate, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. For example, certain features, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the invention in connection with an embodiment. It is also to be understood that the position or arrangement of the individual components within each disclosed embodiment may be varied without departing from the spirit and scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is to be limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly explained. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

In 2007, Google unveiled the Android OS, and several electronic devices based on the Android OS were introduced. In 2011, Android 2.3 (Gingerbread) OS will be released and smart set-top box with Android OS installed in set-top box market. The set-top box equipped with Android OS can serve users by receiving various applications provided by Android Market and developer besides broadcasting reception function using the original digital tuner. For example, a set-top box equipped with an Android OS can provide services such as social network service (SNS), game, video call, media sharing, direct broadcast reception from an Internet broadcasting company, Can be provided to the user.

Most of these features utilize the Internet. As a result, set-top boxes have begun to embed Internet functionality. In recent years, the speed of Wi-Fi (hereinafter referred to as "WLAN") has increased, the wireless LAN has been widely used, and the WLAN Smart set-top boxes with technology have been released.

The smart set-top box can be installed similar to a video cassette recorder (VCR) or a digital versatile disc (DVD) player in the vicinity of the device in order to be connected to a TV in a living room or various display devices. In recent years, however, smart set-top boxes have been developed and released in a much wider variety of configurations, and a set-top box in the form of a high definition multimedia interface (HDMI) dongle, slightly larger than a fist-sized small lightweight set-top box and a universal serial bus . As the shape of the set-top box is diversified, the installation type is also diversified. In this diversified setup, wired LAN cables for the Internet are becoming obstacles to free installation, and smart set-top boxes that can operate based on wireless LAN-based networks are gaining popularity.

Depending on the location of the digital subscriber line (DSL) line, the fiber to the home (FTTH) line, etc. within the user's home, or depending on the structure of the home, proximity to the power supply, They can be installed according to their own judgment. The setup angle varies depending on the user's environment and situation, so that the angle between the smart set-top box and the wireless router also varies.

Smart set-top boxes should be able to provide stable performance in a non-directional manner in order to receive Internet and wireless LAN-based services such as broadcasting without restriction on the angle between the smart set-top box and the wireless router. Therefore, to ensure that the smart set-top box can achieve a non-directional and stable speed, the horizontal rotation angle between the smart set-top box and the wireless router is changed from 0 to 360 degrees and the vertical angle between the smart set-top box and the wireless router is changed from 0 to 90 degrees. The throughput between the wireless router and the smart set-top box can be measured when the wireless LAN-based data is transmitted on the uplink or downlink basis.

Testing for throughput between a wireless router and a smart set-top box during wireless LAN-based data transmission can be performed for various angles facing the wireless router and smart set-top box in 3D space. The bottom of the smart set-top box is horizontal and the floor of the wireless router is horizontal to the ground. The vertical angle of the wireless router is set at 0 degree, and the angle between the front of the smart set- It can be set to 0 and used as a reference.

For example, the vertical angle and the horizontal rotation angle of the wireless router and the smart set-top box for measuring the throughput when transmitting the uplink data based on the wireless LAN can be set as follows. When the vertical angle is 0 degree, the horizontal rotation angle is 0, 10, 20, 30, ... , 350 degrees, and so on. Vertical angles are 10, 20, 30, ... , 90, and the horizontal angle of rotation for each vertical angle is 0, 10, 20, 30, ... , 350 degrees, and the throughput can be measured in transmission of the uplink data based on the WLAN. When such a throughput measurement method is applied to both the uplink and the downlink, throughput measurement for a total of 720 cases can be performed as shown in Table 1 below.

<Table 1>

It may not be practically possible to carry out the entire test case in a situation where the WLAN directionality test is carried out with limited resources such as a small number of persons and a short test period. Therefore, it may be accompanied by the risk of not proceeding with a test or omitting some combinations. Therefore, the wireless LAN directionality test method using the pair-wise technique according to the embodiment of the present invention can measure the throughput during data transmission based on the WLAN using a small directional test case.

1 is a conceptual diagram illustrating a method for measuring uplink throughput and downlink throughput in accordance with an embodiment of the present invention.

1, when the uplink throughput is measured, the PC 100 can perform operations as a client, a server, and a measurement sample (smart set-top box 140). The throughput of the packets that the smart set top box 140 transmits to the PC 100 via the wireless router 120 can be measured in terms of uplink throughput.

1, when the downlink throughput is measured, the PC 100 can perform operations as a client and a measurement sample (smart set-top box 140) as a server. The throughput of the packet that the PC 100 transmits to the smart set top box 140 via the wireless router 120 can be measured by the downlink throughput.

According to the embodiment of the present invention, it is possible to measure the throughput per case corresponding to a specific vertical angle and a specific horizontal rotation angle in order to check the throughput according to the vertical angle and the horizontal rotation angle between the smart set top box and the wireless router have. That is, directionality testing of the wireless LAN can be performed based on checking the vertical angle between the smart set-top box and the wireless router and the throughput per horizontal rotation angle (case). The directional testing of the WLAN can provide users with throughput per case using a graphical interface.

The WLAN directionality test method based on the Fair-Wise method according to the embodiment of the present invention is based on a study result that most defects are caused by interaction of two elements, The wireless LAN directionality measurement for the corresponding case can be performed.

A wireless LAN directional test method based on the Fair-Wise technique can only be performed on a case of one of the two cases of the pair. In order to save time for the combination of test cases, various experts developed and published a tool that can automatically calculate test cases by pair-wise method by listing parameters and various values of each parameter. Allpairs is available at http://www.satisfice.com/testmethod.shtml and is a tool that many testers use because it is easy to use. In the wireless LAN directionality test method based on the Fair-Wise technique according to the embodiment of the present invention, a total of 360 test cases are automatically generated using Allpairs.

Thus, the number of cases tested for wireless LAN directionality testing can be reduced by half. However, when the test of the WLAN directionality is performed selectively, an initial value for providing the result of the WLAN directionality measurement to the graphical interface is not calculated. In other words, if a total of 360 test cases are automatically generated using Allpairs, and the collected result data are plotted in a radial graph using Excel, the shape of the graph is not completed because there is no value of the first case of the vertical angle change. Therefore, there is a possibility that chaos may occur in a region where the problem of the weak region does not occur.

Therefore, according to the embodiment of the present invention, in the case of configuring the radial graph of the current Excel to be used for graphic processing, when the throughput for the downlink is measured, the vertical rotation angle of 0 degrees, 50 °, 70 °, and 90 °, and when measuring the throughput for the uplink, the horizontal rotation angle is 0 ° and the vertical angle is 0 °, 20 °, 40 °, 60 ° and 80 °. can do. The above case is not tested in the WLAN directionality test method based on the existing pair-wise technique. When the WLAN directionality test is performed on the above additional case, an initial start value for a visual expression using a format such as Excel can be obtained.

That is, the form of the radial graph can be completed by adding 5 cases for measuring the throughput on the uplink, 5 cases for measuring the throughput on the downlink, and 10 cases in total.

Table 2 below shows the time required for the test when using the conventional WLAN directionality measurement method and the WLAN directionality measurement method according to the embodiment of the present invention.

<Table 2>

That is, if it takes 30 seconds for each test case and 30 seconds for throughput measurement, one minute of time for each test case can be used for wireless LAN directional test. When the wireless LAN directionality measurement method according to the embodiment of the present invention is used, 6.17 hours can be saved and 48.6% percent of the time can be reduced compared with the conventional method.

Specifically, in terms of shortening the test cases and shortening the time required, it took 720 minutes to complete 720 test cases. However, when the test was performed using the fair-wise technique, the test was carried out with 360 test cases It takes 360 minutes to test all the test elements, but the time required for testing can be shortened by 50% compared to the whole test case. In addition, the addition of 10 minutes for 10 additional test cases to complete the Excel radial graph will save 48.61% compared to the existing test method in 370 minutes. That is, when the wireless LAN directionality measurement method based on the Fairweis technique according to the embodiment of the present invention is used, the test that took 720 minutes except for the test preparation time can be shortened to 370 minutes.

2 is a graph showing the results of the entire test case.

In FIG. 2, the result of performing the wireless LAN directionality measurement on 720 total test cases is shown in a graph.

Referring to FIG. 2, it can be seen that performance degradation of uplink throughput and downlink throughput occurs at vertical angles of 70, 80, 90 degrees and horizontal rotation angles of 10 degrees and 130 degrees.

3 is a graph illustrating a result of performing a simplified test case according to an embodiment of the present invention.

In FIG. 3, the results of WLAN directionality measurement for 370 test cases are shown in a graph.

Referring to FIG. 3, it can be seen that the performance degradation of uplink throughput and downlink throughput occurs at vertical angles of 70, 80, 90 degrees and horizontal rotation angles of 10 degrees and 130 degrees.

When the WLAN directionality test case according to the embodiment of the present invention is performed, the time required for the test is reduced by 48.61% as compared with the case where the entire test case is performed, You can have a result value.

When the wireless LAN directionality test method according to the embodiment of the present invention is used, it is possible to grasp a problematic part, and thus it can be confirmed that there is a problem detection capability.

The WLAN directionality test method according to an embodiment of the present invention can be used in a development step or when testing a prototype product to be delivered to a customer. In various cases that affect the throughput of the wireless LAN such as various obstacles required by the user environment, conditions of simultaneous use with other band (eg 5GHz) wireless LAN, 2.4GHz Bluetooth function and simultaneous use conditions A test can be performed. When the WLAN directionality test method according to the embodiment of the present invention is used for such an exponentially growing test case, problems can be detected in a short time.

4 is a conceptual diagram illustrating a wireless LAN directionality test method according to an embodiment of the present invention.

In Fig. 4, a wireless LAN directionality test based on a plurality of modes is started.

Referring to FIG. 4, the WLAN directionality testing apparatus may operate in one of a plurality of test modes to perform a test for WLAN directionality.

In the first mode 410, when the first mode 410 is selected as the entire test mode, all of the 720 cases described above can be tested.

When the second mode 420 is selected as the simplified test mode, the second mode 420 is a wireless LAN directional test (test for 370 cases) based on the Fair-Wise technique according to the embodiment of the present invention .

When the third mode 430 is selected as the development stage test mode, the third mode 430 may perform only a test on a case included in a certain range selected by the measurer.

For example, if the measurer wishes to test for a range of horizontal rotation angles 0 to 180 degrees at a vertical angle of 70, the measurer can enter the vertical angle and horizontal rotation angle desired to be tested with the WLAN directionality test device, In the directional test apparatus, a test can be performed on the case corresponding to the entered vertical angle and horizontal rotation angle.

In the WLAN directionality test apparatus, the entire test mode or the partial test mode may be selected as the lower mode of the third mode 430. [ When the entire test mode is selected in the lower mode of the third mode 430, a test can be performed on the entire case corresponding to the input vertical angle and the horizontal rotation angle, and the lower mode of the third mode 430 When the partial test mode is selected, only a test of some of the entire cases corresponding to the inputted vertical angle and horizontal rotation angle may be performed.

5 is a conceptual diagram illustrating a wireless LAN directionality test method according to an embodiment of the present invention.

FIG. 5 shows a wireless LAN directionality test procedure of the wireless LAN directionality test apparatus.

Referring to FIG. 5, the WLAN directionality test apparatus may perform a first test (step S500).

The primary test was performed with four horizontal rotation angles (0 degrees, 90 degrees, 180 degrees) for each of the vertical angles (e.g. 0 degrees, 10 degrees, 20 degrees, ..., , &Lt; / RTI &gt; 270 degrees). The case to be subjected to the primary test may be expressed by the term primary test case.

The wireless LAN directionality test apparatus can determine the secondary test target case based on the primary test result (step S510).

The WLAN directionality test apparatus can determine a case where the result value is below the threshold value based on the first test result value. According to the embodiment of the present invention, a priority test can be performed on a case in which the result value is not good.

For example, it can be assumed that the test result value in the case of the primary test object (vertical angle 0 degrees, horizontal rotation angle 90 degrees), (vertical angle 30 degrees, horizontal rotation angle 70 degrees) is below the threshold value. In this case, (vertical angle 0 degrees, horizontal rotation angle 90 degrees), (vertical angle 30 degrees, horizontal rotation angle 70 degrees) may be the secondary test target case. Hereinafter, (X, Y) represents a vertical angle and a horizontal rotation angle, X may be a vertical angle, and Y may be a horizontal rotation angle.

The wireless LAN directionality testing apparatus may perform a second test on a case spatially adjacent to the second test object case (step S520).

The WLAN directionality test apparatus can perform a second test on the case spatially adjacent to the second test object case. The case spatially adjacent to the secondary test object case may be a case adjacent to the secondary test object case in the three-dimensional space. For example, spatially contiguous cases for (0, 90) are (0,70), (0,80), (0,100), (0,110), (10,70), ), (10, 90), (10, 100), (10, 110) These cases spatially adjacent to the secondary test object case are examples. The case spatially adjacent to the secondary test target case may be set to a unit smaller than 10 degrees.

The WLAN directionality test apparatus performs a second test on a plurality of spatially adjacent cases with the second test target case and determines whether the degradation of the uplink throughput and the downlink throughput actually occurs based on the result of the second test Can be determined. If the result of a case that is spatially adjacent to the secondary test case is not good, it can be predicted that the performance of the smart set-top box will deteriorate at the corresponding position.

The test method as shown in Fig. 5 may also be defined as one test mode and selected by the measurer.

Further, the wireless LAN directionality test apparatus according to the embodiment of the present invention can store the result of the previous test and determine the test sequence by considering the result of the previous test. The WLAN directionality test apparatus may also provide information comparing the results of the current test with those of the previous test. For example, the results of previous tests (0, 90) and (0, 90) are spatially contiguous cases (0, 70) ), (10,70), (10,80), (10,90), (10,100), (10,110). When the WLAN directionality test device performs the performance tests on the same smart set-top box and wireless router, it can prioritize the case where the test result is not good considering the previous test result. In addition, the WLAN directionality test apparatus can provide information on changed test results.
