[0038] The technical solution of the present application can be applied to various wireless local area network equipment testing scenarios.

[0039] In the performance test method based on wifi7 wireless LAN equipment, the terminal equipment used in the test system is used. Figure 1 , Figure 1 A schematic diagram of a test system provided for an embodiment of the present application, wherein the test system 10 includes a terminal device 20, a radio frequency controller 30, an analog signal source device 40, a spectrum analyzer 50, and a networking device 60, wherein when performing a performance test based on a wifi7 wireless local area network device, a performance test is performed on the device to be tested 70.

[0040] Among them, the terminal device 20 is the core control unit of the test system 10, which is equipped with test software designed specifically for performance evaluation. This software is responsible for coordinating and controlling the test process to ensure the automation and intelligent execution of the test. The main function is to send instructions to other test components through automated scripts or user interfaces to configure the test process, start and stop the test, and collect and analyze the test results. That is, the test software can send instructions to the measuring equipment, including the RF controller 30, the analog signal source device 40, the spectrum analyzer 50, etc., to execute the predetermined test script.

[0041] Specifically, the terminal device 20 can collect test data, perform analysis and processing, and generate a test report to provide a quantitative evaluation of device performance.

[0042] The RF controller 30 includes a power module, a control module, an IO interface module, a channel switch, a power divider, an adjustable attenuator, etc., which are used to switch the test channel and provide a test environment.

[0043] Specifically, the power module provides a stable power supply for the test system to ensure the continuity and reliability of the test; the control module is responsible for receiving instructions from the terminal device 20, controlling the switching of the RF path, and realizing fast switching of different test items; the IO interface module is used for data communication and instruction transmission with other test equipment; the channel switch, power divider and adjustable attenuator work together to build different RF test environments and simulate the signal transmission conditions in actual use.

[0044] The analog signal source device 40 is used for testing the link loss calibration of the system. Specifically, the analog signal source device can generate a signal with a specific frequency, power and modulation mode to simulate the signal characteristics in a real wireless LAN environment, and by comparing the signal sent by the analog signal source with the received signal, the link loss can be accurately measured, thereby calibrating the test system.

[0045] The spectrum analyzer 50 is used for signal acquisition and measurement, including spectrum template, vector amplitude error, frequency range, out-of-band transmission power and other indicators.

[0046] Specifically, the spectrum analyzer 50 can provide high-precision spectrum analysis to help evaluate the performance of the device under test 70 in terms of radio frequency performance, and can also detect signal stability, interference level, and coexistence capabilities with other wireless devices.

[0047] The networking device 60 is a networking device for multi-link operation (MLO) characteristic measurement. The device can simulate a multi-path transmission environment and test the switching capability and performance of the device under test 70 between multiple access points. The networking device 60 usually includes multiple wireless access points and related network configuration tools to build a complex network topology.

[0048] Among them, the device to be tested 70 is a wireless LAN device that supports 802.11be (wifi7). Including but not limited to access points, routers, wireless network cards, etc. During the test process, the performance of the device will be fully tested to confirm whether it meets the model approval technical requirements stipulated in the document [Guo Wu Ban

[2023] No. 9]. The test results of the device to be tested 70 will directly affect whether it can obtain market access qualifications.

[0049] In view of this, this application proposes a performance test method based on wifi7 wireless local area network equipment to solve the above problems. The following is a detailed introduction.

[0050] See also Figure 2 , Figure 2 A flow chart of a performance test method based on a wifi7 wireless local area network device provided in an embodiment of the present invention, the method comprising the following steps:

[0051] S10, obtaining a calibration coefficient, wherein the calibration coefficient is obtained by calibrating each different test item in the test system respectively.

[0052] The calibration coefficient may be a parameter used to correct the measurement error of the test system, which is not limited here.

[0053] The calibration coefficient can be obtained according to different test items.

[0054] The purpose of calibration is to ensure that the test system can provide accurate measurement results and eliminate or minimize system errors. These errors may come from inherent deviations of the test equipment, environmental factors, or performance changes caused by long-term use.

[0055] Among them, the test items may include but are not limited to three test items: multi-link operation (MLO) characteristics, multi-resource unit (MRU) spectrum template, vector magnitude error (EVM), etc.

[0056] In a specific implementation, when each test item in the test system is calibrated separately, when the test item is a multi-link operation (MLO) feature, the calibration coefficient is used to adjust the signal parameters during the MLO test; when the test item is a multiple resource unit (MRU) spectrum template, the spectrum analyzer 50 is pre-calibrated to ensure that it can accurately measure the usage of the MRU spectrum, and a signal containing a specific spectrum pattern is emitted by the simulated signal source device 40, and the calibration coefficient is adjusted according to the measurement result of the spectrum analyzer 50 to ensure that the test system can accurately evaluate the spectrum efficiency and compliance of the device under test when using MRU; when the test item is a vector magnitude error (EVM), this calibration coefficient is used to adjust the EVM measurement in subsequent tests to ensure that the performance of the device under test in signal quality can be accurately evaluated.

[0057] It can be seen that in this embodiment, by calibrating each test item separately and obtaining their respective calibration coefficients, the test system can provide more accurate and reliable performance evaluation results, which provides a basis for the next step of determining whether the performance of the device to be tested meets the standards of WiFi 7 wireless LAN devices.

[0058] S20: Obtain rule parameters corresponding to the device to be tested, and configure test case parameters corresponding to each different test item in the test system according to the rule parameters.

[0059] The above-mentioned rule parameters refer to the technical specifications and performance standards that the device to be tested needs to comply with. The rule parameters are usually provided by the device manufacturer or defined according to international standards such as IEEE 802.11be (wifi 7). The rule parameters include but are not limited to the device's operating frequency band, maximum transmission power, supported modulation and coding schemes, supported bandwidth, and implementation standards of the MLO feature.

[0060] Among them, obtaining rule parameters usually involves reading technical documents, product manuals or even using specific query tools to obtain them from the device itself, which is not limited here.

[0061] Optionally, in the process of configuring the test case parameters corresponding to each different test item in the test system according to the rule parameters: first, to understand the test items, it is necessary to clarify the purpose and test content of each test item, such as signal strength, data transmission rate, connection stability; secondly, set the test conditions: set the test conditions according to the rule parameters, such as signal frequency, bandwidth, modulation method, coding scheme, etc.; then, adjust the test scope, adjust the test scope according to the rule parameters, and ensure that the test covers all performance requirements that the equipment should meet.

[0062] In specific implementation: for RF power testing, it may be necessary to set the power level, measurement bandwidth and measurement time; for data transmission rate testing, it is necessary to set different data packet sizes, transmission modes and signal strength conditions; for the device under test that supports multi-link operation (MLO), it is necessary to configure the corresponding networking equipment and test process to evaluate its performance under multi-link concurrent operation; for EVM testing, it is necessary to determine the parameters of the test signal based on the highest modulation scheme supported by the device under test to ensure that the test signal can effectively evaluate the receiving performance of the device.

[0063] Among them, the test case parameters define the specific conditions of the test, such as signal frequency, power level, data rate, modulation scheme, etc. They ensure the consistency and standardization of the test and are not limited here.

[0064] It can be seen that in this embodiment, by accurately acquiring and configuring the rule parameters of the device to be tested, the test system can provide a test environment that conforms to the actual application scenario, thereby ensuring that the test results can truly reflect the performance of the device in actual use.

[0065] S30. Send a control instruction to the radio frequency controller, where the control instruction is used to instruct the radio frequency controller to select a test item in the test system to determine a target test item.

[0066] The RF controller acts as the signal management and dispatch center in the test system. It is responsible for generating, receiving, and processing signals, thereby controlling various parameters in the test process, such as frequency, power, channel, etc. By sending specific control instructions to the RF controller, the test system can accurately adjust these variables to perform predetermined test items on the device under test.

[0067] Among them, the control instruction instructs the RF controller to select and execute specific test items in the test system. Control instructions usually include but are not limited to: Test item selection: The instruction will clearly inform the RF controller of the test items that need to be executed, such as data throughput test, signal strength test, etc. Parameter setting: Each test item has its corresponding parameter setting according to the test requirements, and the instruction will contain the setting information of these parameters, such as transmission frequency, signal power, test duration, etc. Execution command: In addition to selection and parameter setting, the control instruction also includes a command to start the selected test item, that is, to let the RF controller start executing the preset test process.

[0068] The control command may be generated by the test software or input manually, and there is no limitation here.

[0069] In the specific implementation, the terminal device generates corresponding control instructions according to the test plan and test case parameters, and sends the control instructions to the RF controller through an appropriate interface (such as USB, Ethernet, serial port, etc.). After receiving the instructions, the RF controller adjusts the internal settings according to the instruction content, and selects and configures the corresponding test items.

[0070] It can be seen that in this embodiment, the flexibility of the test process is increased by using control instructions, and the test items and parameters can be quickly adjusted as needed to adapt to different test requirements. Furthermore, through automated control instructions, the test process can be highly automated, significantly improving test efficiency and reducing human errors.

[0071] S40. Test the target test item according to the test case parameters and the calibration coefficient to obtain a test result, and the test result is used to evaluate whether the device to be tested meets the wifi7 wireless LAN device performance standard on the target test item.

[0072] Among them, the above-mentioned test process may include: the first preparation stage, setting up the test environment and test equipment according to the test case parameters, including configuring the signal source, adjusting the RF controller, setting up the networking equipment, etc.; the second calibration stage, using the calibration coefficients obtained in advance to make appropriate adjustments to the test equipment to ensure accuracy during the test; the third test execution, sending test signals to the device to be tested or performing specific operations in the prepared test environment, while monitoring and recording the device's response and output; the fourth data collection and analysis, collecting the data generated during the test, analyzing it using software tools, and evaluating the test results according to preset performance standards.

[0073] The terminal device tests the target test items of the device under test according to the preset test case parameters. For example, if the target is to test the RF power of the device, the terminal device will send a signal at the set power level and measure the response of the device.

[0074] The test results may include but are not limited to the measured values ​​of various performance indicators, such as data transmission rate, signal-to-noise ratio, bit error rate, etc. By comparing these measured values ​​with the performance standards of WiFi 7, the performance of the device to be tested on each target test item can be evaluated.

[0075] Specifically, if the measurement results meet or exceed the performance standards, it means that the device under test meets the standards for the corresponding test items; otherwise, it means that the device may have defects or insufficient performance in some aspects.

[0076] Among them, the test results can be used to generate a performance test report.

[0077] It can be seen that the test process is fully automated in this embodiment, which greatly improves the test efficiency and test accuracy. That is, it can accurately detect whether the device to be tested reaches or exceeds the standards of WiFi 7 wireless LAN devices in terms of key performance indicators, thereby ensuring the performance of the entire wireless network and user experience.

[0078] S50: Obtain a performance test report of the device to be tested according to the test result.

[0079] The content of the performance test report may include but is not limited to a report overview, a description of the test environment, test items and test case parameters, test results, performance evaluation, or questions and suggestions, which are not limited here.

[0080] For example, the report overview is a brief introduction to the purpose of the test, basic information about the test equipment, test standards, and the scope of the test. The test environment description can be a detailed record of the configuration information of the hardware, software, and other related facilities used in the test. This part ensures the repeatability of the test results. Test items and test case parameters can be a list of all test items and corresponding test case parameters, including but not limited to test conditions, tools and methods used, etc. Test results can be a detailed record of the test data and results of each test item, usually presented in the form of tables, charts, or graphs for easy analysis and understanding. Performance evaluation can be a comprehensive evaluation of the performance of the equipment to be tested based on the test results, which may include comparison with expected performance indicators, comparison with industry standards or previous versions of products, etc. Problems and suggestions point out problems found during the test process, including insufficient equipment performance, potential failure points, and suggestions for improving equipment performance.

[0081] The performance test report may be in paper form, electronic form or other forms, and is not limited here.

[0082] It can be seen that in this embodiment, the performance of the device to be tested is quantitatively evaluated through the performance test report.

[0083] This method is to test whether the device to be tested meets the requirements of the WiFi 7 standard. First, by obtaining the calibration coefficient obtained by calibrating each different test item in the test system, the accuracy of the test result can be ensured. The introduction of the calibration coefficient reduces the system error and improves the credibility of the measurement data. Further, by configuring the test case parameters of each different test item in the test system through the rule parameters of the device to be tested, the test conditions can be ensured to match the device specifications and standard requirements, thereby improving the effectiveness of the test; then based on the test case parameters and the calibration coefficient, the target test item is tested and the test results are obtained, so that it is possible to comprehensively evaluate whether the device to be tested meets the WiFi 7 standard in terms of key performance indicators. Finally, the performance test report formed according to the test results provides a clear performance certificate for device manufacturers, developers and end users. That is, this method can efficiently, accurately and comprehensively evaluate the performance of WiFi 7 devices to ensure that they meet the requirements of the WiFi 7 wireless communication standard.

[0084] In one embodiment, the target test item is a first test item, and the test system also includes a networking device and a spectrum analyzer. The target test item is tested according to the test case parameters and the calibration coefficient to obtain a test result, including: determining, according to the test case parameters, the multi-link operating frequency band supported by the device to be tested in the first test item; obtaining the first calibration coefficient corresponding to the first test item; compensating the spectrum analyzer according to the first calibration coefficient to obtain the compensated first spectrum analyzer; according to the first spectrum analyzer, real-time detection of the first working parameter when the device to be tested and the networking device perform data transmission, the networking device establishes a wifi7 wireless local area network communication connection with the device to be tested, and the device to be tested is in the supported multi-link operating frequency band concurrent state; according to the first working parameter, determining whether the device to be tested passes the first test item.

[0085] Among them, the first test item is the multi-link operation (MLO) feature test. Multi-link operation (MLO) is an advanced wireless technology that allows devices to transmit data on multiple frequency bands simultaneously, improving the efficiency and reliability of data transmission.

[0086] Among them, the multi-link operation frequency band is usually pre-defined according to equipment specifications and standard requirements and is not limited here.

[0087] The spectrum analyzer is compensated according to the first calibration coefficient, which involves adjusting the parameters of the spectrum analyzer to ensure that its measurement results can accurately reflect the actual performance of the device to be tested.

[0088] Among them, the above-mentioned first operating parameters include an operating frequency range and an out-of-band transmission power, and the first operating parameters are key indicators for judging device performance.

[0089] In the specific implementation, the terminal device controls the RF controller to switch to the multi-link operation (MLO) feature test item, and the terminal device controls the device to be tested to automatically set the frequency band supporting MLO according to the test case parameter configuration, and sets the test bandwidth, test channel, test rate, etc., and then turns on the MLO working mode. The terminal device controls the networking device to establish an 802.11be (wifi7) communication connection with the device to be tested. The terminal device calls the data source (such as iperf) to transmit data from the device to be tested to the networking device. At this time, the device to be tested is in a multi-band concurrent state. The terminal device controls the spectrum analyzer to enter the real-time spectrum analysis function to set relevant parameters, which may include but are not limited to RBW, WBW, APT, and set the calibration coefficient compensation to the spectrum analyzer according to this test item, and measure and confirm that the device to be tested is transmitting on the declared working frequency band. If the confirmation is passed, continue the test; otherwise, the confirmation failure message is prompted and the current test case is exited.

[0090] For example, in the multi-band concurrent state, the operating frequency range and out-of-band transmission power of the relevant wireless LAN equipment should comply with the relevant requirements of Document No. 129. 1. Operating frequency range: 2400-2483.5MHz, 5150-5350MHz and 57255850MHz. 2. Out-of-band transmission power: the maximum equivalent isotropic radiated power at the upper and lower limits of the use frequency is not greater than -80dBm / Hz. Therefore, we can configure the device to be tested to work in multi-link operation mode, establish a data link between the device to be tested and the networking device, use a spectrum analyzer with real-time spectrum analysis capability to ensure that the device to be tested transmits on the declared working frequency band, use a spectrum analyzer with spectrum analysis function to measure the frequency range and out-of-band transmission power of the device to be tested, and measure and confirm that the device to be tested transmits on the declared working frequency band. If confirmed to be passed, continue the test; otherwise, a confirmation failure message is prompted and the current test case is exited.

[0091] It can be seen that the terminal device in this embodiment can comprehensively detect the performance of the device to be tested in the frequency band that supports multi-link operation, confirm whether it meets the performance standards of WiFi 7 wireless LAN devices, improve test efficiency and accuracy, and reduce manpower investment costs.

[0092] In one embodiment, the first operating parameter includes an operating frequency range and an out-of-band transmission power, and determining whether the device to be tested passes the first test item based on the first operating parameter includes: judging whether the operating frequency range is within a preset frequency range, and judging whether the out-of-band transmission power satisfies a preset transmission power rule; when the operating frequency range is within the preset frequency range, and the out-of-band transmission power satisfies the preset transmission power rule, determining that the device to be tested passes the first test item.

[0093] The preset frequency range is a preset operating frequency range set according to the standard requirements of Wi-Fi 7 wireless LAN equipment. The preset frequency is usually a combination of multiple frequency bands, 2400-2483.5MHz, 5150-5350MHz, 5725-5850MHz, etc.

[0094] Among them, only when the operating frequency of the device to be tested completely covers the preset frequency range can it be ensured that it is compatible with the expected wireless environment and can operate normally.

[0095] The above-mentioned preset transmit power rule refers to the maximum allowable transmit power level of the device in areas outside the specified frequency (out-of-band). This is usually used to limit the potential interference of the device to other wireless services. The preset transmit power rule usually requires that the maximum equivalent isotropic radiated power at the upper and lower limits of the frequency is no more than -80dBm / Hz.

[0096] Specifically, the terminal device needs to comprehensively determine whether the operating frequency range and the out-band transmission power meet the preset requirements at the same time. Only when the operating frequency range is within the preset frequency range and the out-band transmission power meets the preset transmission power rules, will it be determined that the device to be tested has passed the first test item.

[0097] It can be seen that the terminal device in this embodiment can comprehensively evaluate the performance of the device to be tested in the multi-link operation (MLO) characteristic test to ensure that it meets the performance standards of WiFi 7 wireless LAN devices.

[0098] In one embodiment, the test system also includes a spectrum analyzer, the target test item is a second test item, and the target test item is tested according to the test case parameters and the calibration coefficient to obtain a test result, including: determining the preamble code puncturing channel number value corresponding to the second test item according to the test case parameters; obtaining the second calibration coefficient corresponding to the second test item; compensating the spectrum analyzer according to the second calibration coefficient to obtain a compensated second spectrum analyzer; detecting the second working parameters of the device to be tested in a signal transmission state in real time according to the second spectrum analyzer, preset test requirements and the preamble code puncturing channel number value; and judging whether the device to be tested passes the second test item according to the second working parameters.

[0099] The second test item is the multiple resource unit (MRU) spectrum mask. The multiple resource unit (MRU) spectrum mask test is mainly aimed at evaluating the performance of the device under test in a specific spectrum environment and checking whether the device can comply with specific spectrum usage requirements when transmitting signals, especially the radiation limits at different frequency offsets.

[0100] The above-mentioned preamble code puncturing channel number value is predefined based on equipment specifications and standard requirements, especially for the 20 MHz bandwidth preamble code puncturing at non-edge positions.

[0101] The above-mentioned preset test requirements may be center frequency, resolution bandwidth, video bandwidth, detection mode, measurement frequency and limit value, etc. If the preset test requirements are measurement frequency and limit value, they may be as shown in the following table:

[0102] Measurement frequency (frequency offset Δf from the edge of the occupied subchannel) Limits 0MHz≤Δf<0.5MHz 0-20dBr2 0.5MHz≤Δf<10MHz 20-23dBr2 10MHz≤Δf<19.5MHz 20-23dBr2 19.5MHz<Δf≤20MHz 0-20dBr2

[0103] The second working parameter is a measurement result read by the spectrum analyzer.

[0104] In a specific implementation, the terminal device controls the RF controller to switch to the multiple resource unit (MRU) spectrum mask test item. After the terminal device controls the device to be tested to automatically set the test bandwidth, test channel, test rate, preamble puncturing channel number value (only required for non-edge position 20MHz bandwidth preamble puncturing) and other parameters according to the test case parameter configuration, the terminal device controls the device to be tested to be in a signal transmission state. The terminal device controls the spectrum analyzer to enter the spectrum analysis mode and sets the relevant parameters according to the preset requirements, and sets the calibration coefficient compensation to the spectrum analyzer according to this test item. The terminal device calculates the measurement frequency and limit value according to the preamble puncturing channel number value and test requirements set above, and then sets them to the spectrum analyzer, controls the spectrum analyzer to start scanning until the measurement is completed, and the terminal device reads the measurement results of the spectrum analyzer.

[0105] Among them, the preset requirements can be as shown in the following table:

[0106] Center frequency The center frequency of the device under test Resolution bandwidth 100kHz Video Bandwidth 7.5kHz Detection method Effective value (RMS)

[0107] The above table means that the device under test is connected to a spectrum analyzer with demodulation function through an RF line, the center frequency of the spectrum analyzer is adjusted to the center frequency of the device under test, the resolution bandwidth (RBW) is set to 100kHz, the video bandwidth (VBW) is set to 7.5kHz, the detection mode is set to the effective value (RMS), and the spectrum envelope of the signal emitted by the device under test should meet the above-mentioned spectrum template requirements.

[0108] It can be seen that the terminal device in this embodiment can comprehensively evaluate the performance of the device to be tested on the multi-resource unit (MRU) spectrum mask test item to ensure that it can meet the performance standards of WiFi 7 wireless LAN devices.

[0109] In one embodiment, the test system also includes a spectrum analyzer, the target test item is a third test item, and the target test item is tested according to the test case parameters and the calibration coefficient to obtain a test result, including: determining the modulation working mode corresponding to the third test item according to the test case parameters; setting the spectrum analyzer to a demodulation measurement mode based on the wifi7 wireless local area network to obtain a spectrum analyzer in the demodulation measurement mode; obtaining a third calibration coefficient corresponding to the third test item; compensating the spectrum analyzer in the demodulation measurement mode according to the third calibration coefficient to obtain a compensated third spectrum analyzer; according to the third spectrum analyzer, real-time detection of the third working parameter of the device to be tested during data transmission; detecting whether the third working parameter is less than a preset vector amplitude error threshold, and if so, determining that the device to be tested passes the third test item.

[0110] Among them, the third test item is the vector magnitude error (EVM) test item. Vector magnitude error (EVM) is an important indicator to measure the amplitude and phase error of the modulated signal. For wireless communication equipment, the lower the EVM value, the higher the signal quality and the better the modulation performance. In high-performance wireless communication standards (such as WiFi 7), the device is required to have a lower EVM value to ensure that high-speed data can be effectively transmitted and the signal quality can be maintained.

[0111] The preset vector amplitude error threshold may be -38 dB.

[0112] Among them, the above modulation working modes are pre-defined based on equipment specifications and standard requirements, such as QAM, OFDM, etc.

[0113] Among them, the spectrum analyzer is set to the demodulation measurement mode based on the WiFi 7 wireless LAN. In this mode, the spectrum analyzer can demodulate the received wireless signal in real time and perform a detailed analysis on it.

[0114] The third operating parameter is the vector magnitude error EVM.

[0115] It is checked whether the measured vector magnitude error (EVM) is less than a preset vector magnitude error threshold. If so, it means that the modulation quality of the device to be tested meets the standard, thereby determining that the device has passed the third test item.

[0116] In the specific implementation, the terminal device controls the RF controller to switch to the vector amplitude error (EVM) test item. The terminal device controls the device to be tested to automatically set the test bandwidth, test channel, and modulation to 4096QAM working mode according to the test case parameter configuration, and controls the device to be tested to be in the signal transmission state. The terminal device controls the spectrum analyzer to enter the demodulation measurement mode of 802.11be (wifi7), and sets the calibration coefficient compensation of this measurement channel to the spectrum analyzer. The terminal device controls the spectrum analyzer to start scanning until the measurement is completed. The terminal device reads the EVM Avg test result measured by the spectrum analyzer, and the test result should be less than -38dB.

[0117] For example, connect the device to be tested to a spectrum analyzer with demodulation function through an RF cable, set the device to be tested to send a 4096QAM modulated signal, and measure the EVM Avg test result (the third working parameter mentioned above) through the spectrum analyzer. The measurement result should meet the above-mentioned technical requirements (such as the test result should be less than -38dB).

[0118] It can be seen that the terminal device in this embodiment is sufficient to comprehensively evaluate the performance of the device to be tested on the vector amplitude error (EVM) test item to ensure that it can meet the performance standards of wifi 7 wireless LAN devices. In one embodiment, the test system also includes an analog signal source device and a spectrum analyzer, and the analog signal source device is connected to the spectrum analyzer through a calibration reference line, and the acquisition of the calibration coefficient includes: sending a first instruction to the analog signal source device, the first instruction is used to indicate the multiple signals sent by the analog signal source device at different frequencies; receiving multiple signal coefficients sent by the spectrum analyzer, the signal coefficients are the signal coefficients of the analog signal source device after sending signals at different frequencies collected by the spectrum analyzer; according to the multiple signal coefficients, determine the reference coefficient; according to the reference coefficient, calibrate each different test item in the test system to obtain the calibration coefficient corresponding to each different test item.

[0119] Among them, the analog signal source device is responsible for generating controllable and precise signals. By sending instructions to this device, signals can be generated under different frequencies, power levels, etc. to simulate various signal environments that the device may encounter under actual operating conditions.

[0120] Among them, the spectrum analyzer is responsible for accurately measuring and analyzing the spectrum of the signal. When connected to an analog signal source device, it can accurately capture and analyze the signal emitted by the signal source to evaluate the signal's quality, power, frequency and other characteristics.

[0121] Among them, the calibration reference line is the physical connection line connecting the analog signal source device and the spectrum analyzer. It ensures that the signal is not attenuated or distorted during the transmission process, thereby ensuring the accuracy of the calibration.

[0122] The first instruction is used to instruct the analog signal source device to send multiple signals at different frequencies, and the signals simulate signal conditions that may be encountered in actual testing.

[0123] The above signal coefficients are parameters such as power, frequency, phase, etc. of the signal collected by the spectrum analyzer.

[0124] Optionally, the reference coefficient required at each frequency is calculated based on the signal coefficient collected by the spectrum analyzer.

[0125] Among them, reference coefficients are quantitative indicators of the difference between actual measured values ​​and ideal values, and they are used to adjust measurement errors in subsequent tests.

[0126] The calibration coefficient will be used to correct the measurement data in the actual test.

[0127] It can be seen that in this embodiment, by calculating the calibration coefficient, errors in the test results during the calibration process due to the measurement deviation of the equipment itself are further avoided, the accuracy of the test results is guaranteed, and it is ensured that even if the test is performed at different times and in different environments, the results obtained are highly repeatable.

[0128] In one embodiment, determining a reference coefficient based on the multiple signal coefficients includes: obtaining the difference between the multiple signal coefficients; if there is a difference greater than a preset threshold, determining that there is an abnormality in the two signal coefficients corresponding to the difference; and calculating the mean of other signal coefficients except the two signal coefficients corresponding to the difference to obtain a reference coefficient.

[0129] The difference is a quantitative index used to represent the difference between signal coefficients. Calculating the difference usually involves comparing the difference between each signal coefficient and other signal coefficients.

[0130] The preset threshold is used to determine whether the difference between the signal coefficients is within an acceptable range. The preset threshold is determined according to specific test requirements and standards, and is not limited here.

[0131] If the calculated difference is greater than a preset threshold, this indicates that the difference between the two signal coefficients exceeds a normal range, which may be caused by system error, equipment failure or other factors.

[0132] Once it is determined that there are abnormal signal coefficients (ie, their difference exceeds a preset threshold), the abnormal signal coefficients will be excluded from subsequent calculations in order to avoid the influence of abnormal data on the final result.

[0133] Among them, the mean is the average value of all remaining signal coefficient values ​​after excluding abnormal signal coefficients, which represents the average performance of the system in the absence of abnormalities.

[0134] The reference coefficient is obtained by calculating the average of other signal coefficients except the abnormal signal coefficient. The reference coefficient provides a benchmark for evaluating and calibrating the measurement performance of the test system.

[0135] It can be seen that the reference coefficient process in this embodiment is achieved by identifying and excluding abnormal signal coefficients and calculating the mean of the remaining signal coefficients. This process ensures the accuracy and reliability of the reference coefficients, provides a solid foundation for subsequent test item calibration, and thus enhances the accuracy and repeatability of the test results. Through such a calibration process, the overall performance and credibility of the test system can be significantly improved.

[0136] In one embodiment, calibrating each different test item in the test system according to the reference coefficient to obtain the calibration coefficient corresponding to each different test item includes: sending a second instruction to the analog signal source device, the second instruction is used to instruct the analog signal source device to send a signal to the RF controller, the analog signal source device is connected to the RF controller through the calibration reference line; controlling the RF controller to test each different test item in the test system to obtain the total channel coefficient corresponding to each different test item; and calibrating the total channel coefficient corresponding to each different test item according to the reference coefficient to obtain the calibration coefficient corresponding to each different test item.

[0137] The second instruction is used to instruct the analog signal source device to send a signal to the radio frequency controller.

[0138] Among them, the analog signal source device is connected to the RF controller through a calibration reference line to ensure that the signal remains stable and accurate during transmission.

[0139] During the test, the RF controller measures the total channel coefficient for each test item. The total channel coefficient includes the total gain, total loss and other factors that affect signal performance when the signal passes through the RF path.

[0140] In the process of calibrating the total channel coefficient corresponding to each different test item according to the reference coefficient, the following formula can be used: calibration coefficient of test item=total channel coefficient-reference coefficient.

[0141] For example, the analog signal source device is connected to the RF controller through the calibration reference line, and the terminal device controls the RF controller to switch to the multi-link operation (MLO) characteristic test item. After the terminal device is calibrated, the data is saved. The calibration coefficient of this test item = channel total coefficient - reference coefficient. Similarly, the calibration coefficients of the multi-resource unit (MRU) spectrum mask test item and the vector magnitude error (EVM) test item are calibrated respectively.

[0142] It can be seen that in this embodiment, by sending test signals, collecting test data, and using reference coefficients for calibration, an exact calibration coefficient is assigned to each test item of the test system, further ensuring that the test system can provide accurate and reliable test results in product development, quality control and other occasions.

[0143] It should be noted that, in each of the above-mentioned embodiments, there is not necessarily a certain order between the above-mentioned steps. A person skilled in the art can understand, based on the description of the embodiments of the present application, that in different embodiments, the above-mentioned steps may have different execution orders, that is, they may be executed in parallel, may be executed interchangeably, and so on.

[0144] As another aspect of the embodiment of the present application, the embodiment of the present application provides a performance testing device based on a wifi7 wireless LAN device. Among them, the performance testing device based on a wifi7 wireless LAN device can be a software module, and the software module includes a number of instructions, which are stored in a memory, and the processor can access the memory and call the instructions for execution to complete the performance testing method based on the wifi7 wireless LAN device described in the above-mentioned various embodiments.

[0145] See also Figure 3 , Figure 3 Schematic diagram of a performance test device based on a wifi7 wireless local area network device provided in an embodiment of the present application.

[0150] The determination unit 304 is used to obtain a performance test report of the device to be tested according to the test result.

[0151] This method is to test whether the device to be tested meets the requirements of the WiFi 7 standard. First, by obtaining the calibration coefficient obtained by calibrating each different test item in the test system, the accuracy of the test result can be ensured. The introduction of the calibration coefficient reduces the system error and improves the credibility of the measurement data. Further, by configuring the test case parameters of each different test item in the test system through the rule parameters of the device to be tested, the test conditions can be ensured to match the device specifications and standard requirements, thereby improving the effectiveness of the test; then based on the test case parameters and the calibration coefficient, the target test item is tested and the test results are obtained, so that it is possible to comprehensively evaluate whether the device to be tested meets the WiFi 7 standard in terms of key performance indicators.
