[0054] Example 1

[0055] The embodiment of the present application provides a WiFi throughput test system based on an anechoic chamber.

[0056] See also Figure 1 , Figure 1 A schematic diagram of a WiFi throughput test system based on an anechoic chamber provided in an embodiment of the present application is shown, including: an antenna lifting tower 200, an electromagnetic compatibility test antenna 400, a WiFi throughput test antenna 500, an auxiliary test device 300, a WiFi throughput test equipment test stand 100 and a control device.

[0057] The electromagnetic compatibility test antenna 400 and the WiFi throughput test antenna 500 are installed on the antenna lifting tower 200, wherein the WiFi throughput test antenna 500 is below the electromagnetic compatibility test antenna 400; the auxiliary test equipment 300 is arranged on the back side of the WiFi throughput test antenna 500, and the auxiliary test equipment is separated from the WiFi throughput test antenna by a first preset distance; the WiFi throughput test equipment test stand is arranged on the direction facing the WiFi throughput test antenna; the WiFi throughput test equipment test stand is separated from the WiFi throughput test antenna by a second preset distance; the control device is arranged to be electrically connected to the auxiliary test equipment 300 and the WiFi throughput test equipment test stand 100 respectively; the antenna lifting tower, the electromagnetic compatibility test antenna, the WiFi throughput test antenna, the auxiliary test equipment and the WiFi throughput test equipment test stand are respectively arranged in an anechoic chamber.

[0058] It should be noted that the auxiliary test equipment 300 is set at a position close to the wall on the back of the WiFi throughput test antenna 500 on the antenna lifting tower 200. The first preset distance needs to be set according to actual needs. The farther the distance, the better the effect. In this embodiment, the auxiliary test equipment 300 is set at a position 2 meters away from the back of the WiFi throughput test antenna 500 on the antenna lifting tower 200 for testing.

[0059] The WiFi throughput test equipment test stand 100 is set at a second preset distance of more than 20 cm in the direction of the WiFi throughput test antenna 500 of the antenna lifting tower 200. The specific setting can be based on actual needs. In this embodiment, the test distance is set to 30 cm.

[0060] Specifically, the control device is electrically connected to the auxiliary test device 300 and the WiFi throughput test device test frame 100 respectively, the device to be tested is placed above the WiFi throughput test device test frame 100, the test distance is electrically controlled on the control device according to demand, and the WiFi throughput test is performed remotely on the device to be tested through the auxiliary test device 300.

[0061] In one embodiment, the auxiliary test equipment 300 includes: an adjustable attenuator 301, a first photoelectric converter 302, a radio frequency switch 303, a test auxiliary equipment network card 304 and a test auxiliary equipment router 305; the first photoelectric converter 302 is respectively connected to the adjustable attenuator 301, the test auxiliary equipment router 305, the test auxiliary equipment network card 304 and the radio frequency switch 303 through a communication network cable 308; the first photoelectric converter 302 is electrically connected to the control device through a first optical fiber line 307.

[0062] In this embodiment, if Figure 2 As shown, the WiFi throughput test is completed by the following steps: Step 1, place the device under test on the turntable and turn on the WiFi of the device under test. Step 2, determine the type of the device under test. If the device under test is an AP (Access Point, wireless access point) device, such as a router, turn on the test auxiliary device network card 304, switch to the auxiliary device network card through the RF switch 303, connect the network card to the sample, and establish a WiFi connection between the two; if the sample is a STA (Station, station )Device, such as a mobile phone, then turn on the test auxiliary device router 305, switch to the auxiliary device router through the RF switch 303, the router connects to the sample, and the two establish a WiFi connection. Step 3, the test software controls the adjustable attenuator 301 and the turntable to return to their positions through the photoelectric converter, the adjustable attenuator 301 is set to 0db attenuation, and the turntable is turned to 0 degrees. Step 4, set the test duration, start the WiFi throughput test between the auxiliary device and the device under test, after the test is completed, increase the attenuator value according to the set calculation method until the WiFi throughput test cannot be performed, then reset the attenuator value to 0db. Step 5, rotate the turntable to the next angle, repeat step 4, until the turntable rotates to 360 degrees, then the test is completed, and the test data is saved.

[0063] In one embodiment, the RF switch 303 is electrically connected to the adjustable attenuator 301 , the test auxiliary equipment router 305 and the test auxiliary equipment network card 304 via a RF line 306 ; the adjustable attenuator 301 is electrically connected to the WiFi throughput test antenna 500 via the RF line 306 .

[0064] In one embodiment, the WiFi throughput test equipment test frame 100 includes: a controllable slide rail 103, a horizontal rotating turntable 101, a test frame base 104, a turntable mast 102 and a control module 105; the horizontal rotating turntable 101 is arranged above the controllable slide rail 103 through the turntable mast 102; the controllable slide rail 103 and the control module 105 are arranged above the test frame base 104; the control module 105 is electrically connected to the control device through a second optical fiber line 107.

[0065] like Figure 3 As shown, when the existing darkroom turntable 600 does not meet the test winding requirements and the distance between the antenna and the sample cannot be adjusted, this test stand can be selected. The WiFi throughput test equipment test stand 100 includes a controllable slide rail 103 and a 360-degree horizontal rotation turntable 101. The controllable slide rail 103 is used to adjust the horizontal distance between the WiFi throughput test antenna 500 and the device under test, and the 360-degree horizontal rotation turntable 101 is used to replace the darkroom turntable 600 to complete the angle rotation test.

[0066] In one embodiment, the control module 105 includes: a control motor and a second photoelectric converter; the control motor is electrically connected to the second photoelectric converter; and the second photoelectric converter is electrically connected to the control device via the second optical fiber line 107 .

[0067] In one embodiment, the system further includes: a third photoelectric converter; the third photoelectric converter is communicatively connected to the first photoelectric converter 302 via the first optical fiber line 307; the third photoelectric converter is communicatively connected to the second photoelectric converter via the second optical fiber line 107; and the control device is electrically connected to the third photoelectric converter.

[0068] It should be noted that the third photoelectric converter and the control device control the progress of the WiFi throughput test outside the radio wave darkroom. The antenna lifting tower 200, the electromagnetic compatibility test antenna 400, the WiFi throughput test antenna 500, the auxiliary test equipment 300 and the WiFi throughput test equipment test stand 100 are all inside the radio wave darkroom. The inner wall of the radio wave darkroom is attached with absorbing foam. The absorbing foam can absorb and scatter electromagnetic waves to reduce the interference and influence of electromagnetic waves, thereby improving the electromagnetic purity of the test environment, effectively absorbing and scattering electromagnetic waves, reducing the propagation intensity of electromagnetic waves in space, helping to reduce the interference of external electromagnetic waves on the test, and improving the accuracy and reliability of the test.

[0069] In one implementation, the WiFi throughput test equipment test stand 100 further includes: a communication interface 106 ; the communication interface 106 is disposed on the side of the horizontal rotating turntable 101 .

[0070] Specifically, the communication interface 106 may be a reserved USB interface, HDMI (High Definition Multimedia Interface, a fully digital audio and video interface) interface or infrared interface. By reserving the communication interface 106, the tangling problem caused by too many communication wires can be avoided.

[0071] In one embodiment, the system further includes: a device under test; the device under test is arranged above the horizontal rotating turntable 101 ; and the auxiliary test device 300 is communicatively connected with the device under test via the communication interface 106 .

[0072] It should be noted that after the device under test is powered on through the communication interface 106 , WiFi is turned on, a communication connection is established with the auxiliary test device 300 through WiFi, and the WiFi throughput of the device under test is tested using the auxiliary test device 300 .

[0073] In one implementation, the electromagnetic compatibility test antenna 400 is a Vivaldi antenna or a log-periodic antenna.

[0074] It should be noted that the log-periodic antenna is a wide-band antenna, also known as a non-frequency-variant antenna. Its characteristics are that the antenna's electrical characteristics such as impedance, radiation pattern, gain, and standing wave ratio change periodically with the logarithm of the frequency and remain basically unchanged within a very wide frequency band. The Vivaldi antenna is a common plane broadband antenna. The Vivaldi antenna has broadband performance and takes into account multiple frequency ranges, enabling it to work in multiple frequency bands simultaneously.

[0075] It is further explained that the WiFi protocol supports up to 16 antennas. In this embodiment, four Vivaldi antennas or log-periodic antennas are used as transmission tools.

[0076] In one embodiment, the system further includes: a darkroom turntable 600; the darkroom turntable 600 includes: a test table and a turntable base; the test table is placed above the turntable base.

[0077] It should be noted that if Figure 4 As shown, the darkroom turntable 600 can rotate 360°, and the test process is used to switch the transmission / reception angle of the test sample. According to the complexity, automation and winding problems of the actual test setup, one of the WiFi throughput test equipment test stand 100 and the darkroom turntable 600 can be selected to place the device to be tested.

[0078] The utility model provides a WiFi throughput test system based on an anechoic chamber, comprising: an antenna lifting tower 200, an electromagnetic compatibility test antenna 400, a WiFi throughput test antenna 500, an auxiliary test device 300, a WiFi throughput test device test stand 100 and a control device; the electromagnetic compatibility test antenna 400 and the WiFi throughput test antenna 500 are both installed on the antenna lifting tower 200, wherein the WiFi throughput test antenna 500 is located below the electromagnetic compatibility test antenna 400; the auxiliary test device 300 is arranged on the back side of the WiFi throughput test antenna 500; the auxiliary test device 300 and the WiFi throughput test device are connected to each other. The WiFi throughput test antenna 500 is spaced apart by a first preset distance; the WiFi throughput test equipment test stand 100 is arranged in the direction of the WiFi throughput test antenna 500; the WiFi throughput test equipment test stand 100 and the WiFi throughput test antenna 500 are spaced apart by a second preset distance; the control device is electrically connected to the auxiliary test equipment 300 and the WiFi throughput test equipment test stand 100 respectively; the antenna lifting tower 200, the electromagnetic compatibility test antenna 400, the WiFi throughput test antenna 500, the auxiliary test equipment 300 and the WiFi throughput test equipment test stand 100 are arranged in an anechoic chamber. The utility model proposes a WiFi throughput test system based on an anechoic chamber, which tests WiFi throughput on the basis of the original anechoic chamber, and the test distance and test angle can be automatically adjusted according to the demand through the WiFi throughput test equipment test stand 100, which saves the cost of the anechoic chamber construction and the site space required for the construction.
