[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Example 1

[0061] Please refer to Figures 1-2 Embodiment 1 of the present invention provides a WIFI performance testing device, the device including a signal transmission module 1, a support base 2, a lifting mechanism 3, a cover 4 and a control module 5;

[0062] Specifically, the signal transmitting module 1 and the lifting mechanism 3 are respectively connected to the control module 5. This communication connection ensures that the control module 5 can effectively transmit commands and receive status feedback from the signal transmitting module 1 and the lifting mechanism 3, thereby achieving precise control operations.

[0063] The support base 2 serves as the load-bearing component in the entire device, primarily used to place the terminal 10, which is to be tested for WIFI performance. By stably supporting the terminal 10, it provides a solid foundation for subsequent testing operations.

[0064] The cover 4 is designed with specific functionality in mind. It can cooperate with the support base 2 to close, thereby forming a relatively sealed space. The formation of this sealed space is of great significance for simulating specific test environments and reducing the influence of external interference factors on test results.

[0065] The lifting mechanism 3 is cleverly positioned above the support base 2 and connected to the cover 4. Under the control of the control module 5, the lifting mechanism 3 can drive the cover 4 to descend, gradually approaching the support base 2. Different test conditions correspond to the dynamic process of the cover 4 gradually approaching the support base 2, and to the point where the cover 4 finally completely closes with the support base 2 to form a sealed space. These different test conditions will have varying degrees of impact on the terminal 10's reception of the WIFI test signal. Changes in signal strength, signal stability, and fluctuations in other related performance indicators may all vary depending on the test conditions. Therefore, in order to comprehensively and accurately evaluate the WIFI performance of the terminal 10 under different test conditions, corresponding WIFI performance tests need to be conducted for both of these different test scenarios.

[0066] The primary responsibility of the signal transmitting module 1 is to output WiFi test signals according to predetermined parameters and requirements under the control of the control module 5. These test signals serve as a key basis for evaluating the WiFi performance of the terminal 10, and their accuracy, stability, and consistency play a crucial role in the reliability of the test results.

[0067] The control module 5 plays a core role in the entire device, handling both control and data processing. It is responsible not only for accurately controlling the signal transmission module 1 and the lifting mechanism 3, ensuring they operate precisely according to preset programs and requirements, but also for receiving test data from the terminal 10. Upon receiving the test data from the terminal 10, the control module 5 uses its built-in data processing algorithms and logic to perform in-depth analysis and processing of this data, ultimately generating accurate WiFi test results.

[0068] The WIFI performance testing device designed in this embodiment of the invention, through the ingenious setting of the control module 5, which centrally controls the signal transmission module 1 and the lifting mechanism 3, and the reasonable arrangement of the cooperation between the support base 2 and the cover 4, successfully achieves fully automated operation of the testing process. This fully automated operation mode has significant advantages; it eliminates the need for manual adjustment of test conditions, greatly reducing labor and time costs. In traditional manual testing methods, manually adjusting test conditions is not only inefficient but also prone to errors, while the automated design of this embodiment of the invention effectively avoids these problems.

[0069] Meanwhile, since the entire testing process is automated by control module 5, interference from human factors is reduced, thus avoiding human error and greatly improving the accuracy and reliability of the test. Regarding test result feedback, control module 5 can receive test data sent from the terminal in real time and quickly generate test results, achieving real-time feedback. This real-time feedback mechanism enables testers to promptly identify problems and take corresponding measures for adjustment and improvement, improving testing efficiency and the timeliness of problem resolution.

[0070] Furthermore, this device possesses the capability for long-term stable operation, enabling it to complete continuous testing tasks. Through continuous testing of terminal 10 under different test conditions, its WIFI performance can be comprehensively and thoroughly evaluated, providing an efficient and accurate testing method for terminal production and quality control. This testing method not only helps manufacturers promptly identify problems in product WIFI performance for targeted improvements and optimizations, but also provides strong data support for product quality control, ensuring that product quality meets relevant standards and requirements. Therefore, the WIFI performance testing device provided in this embodiment of the invention has significant application value and broad application prospects in the field of terminal production and quality control.

[0071] Please refer to this again. Figure 1 In one embodiment of this example, the cover 4 includes two half-covers 41 and a driver 42;

[0072] From a structural connection perspective, the two half-covers 41 are connected in a closable manner. This closable connection design allows the two half-covers 41 to flexibly open and close according to actual testing needs. They can be closed together to form a complete cover structure when needed, or separated when necessary, providing convenient space for the placement, removal, and other related operations of the terminal. This design fully considers the actual operational needs during the testing process, improving the ease of use and flexibility of the device.

[0073] The actuator 42 is used to precisely drive the two half-covers 41 to open and close. After the test begins, when the lifting mechanism 3 lowers the cover 4 to its position, the actuator 42 drives the two half-covers 41 to move towards the center, so as to completely cover the support base 2 and form a sealed space. After the test is completed, the actuator 42 will drive the two half-covers 41 to separate to the sides, so as to unlock the cover from the support base 2, so that the lifting mechanism 3 can drive the cover 4 to rise and reset, thereby smoothly removing the terminal 10 from the support base 2.

[0074] This cover structure 4, consisting of two half-covers 41 and a driver 42, not only meets the functional requirements of WIFI performance testing, but also demonstrates a high degree of rationality and innovation in its design. Through precise drive control and flexible opening and closing actions, it provides strong support for the automated operation of the entire testing device, further improving the efficiency and convenience of the testing process.

[0075] Please refer to this again. Figures 1-2 In one embodiment of this invention, the device is further equipped with a monitoring module 6 on the basis of the original structure. This design greatly improves the automation control level and testing accuracy of the device.

[0076] From the perspective of connection and functional positioning, the monitoring module 6 is communicatively connected to the control module 5. This communication connection ensures that the monitoring module 6 can transmit the acquired data to the control module 5 in real time and accurately, providing a reliable basis for subsequent control decisions. The core function of the monitoring module 6 is to monitor the descent height of the lifting mechanism 3. During the descent of the cover 4 driven by the lifting mechanism 3, the monitoring module 6 continuously and uninterruptedly collects the real-time height position information of the lifting mechanism 3. This information covers the height node data of the entire process from the start of descent to approaching the support base 2, until finally closing with the support base 2. Through the accurate collection of this height position data, the monitoring module 6 can grasp the movement status and position changes of the lifting mechanism 3 in real time.

[0077] After data acquisition is complete, the monitoring module 6 quickly and accurately transmits this monitoring data to the control module 5. Upon receiving the data from the monitoring module 6, the control module 5 immediately analyzes it. Based on the analysis results, the control module 5 can accurately determine whether the current descent height of the lifting mechanism 3 meets the preset test requirements. If a deviation is found in the descent height of the lifting mechanism 3, whether too high or too low, the control module 5 will promptly issue corresponding control commands to the lifting mechanism 3 according to the preset control strategy to precisely adjust its descent height.

[0078] This collaborative working mechanism between the monitoring module 6 and the control module 5 enables closed-loop control of the descent height of the lifting mechanism 3. Compared to traditional open-loop control, closed-loop control can adjust the control strategy promptly based on real-time monitoring data, greatly improving the accuracy and reliability of the control. In the WIFI performance testing device of this embodiment, this precise height control is crucial. Different descent heights correspond to different test conditions, and the accuracy of these test conditions directly affects the effectiveness of the terminal 10 in receiving the WIFI test signal, thus determining the accuracy and reliability of the test results. By ensuring that the lifting mechanism 3 can accurately descend to the preset height, the device of this embodiment can create a more stable and consistent testing environment for the terminal 10, thereby obtaining more accurate and reliable WIFI performance test results.

[0079] Furthermore, the addition of monitoring module 6 facilitates fault diagnosis and maintenance of the device. Through long-term recording and analysis of monitoring data, operators can promptly identify any abnormalities that may occur during the operation of the lifting mechanism 3, such as unstable movement or excessive positional deviation, and perform targeted maintenance and repair accordingly, thereby extending the service life of the device and reducing maintenance costs.

[0080] In summary, the addition of a monitoring module 6 in one embodiment of this invention, which works in conjunction with the control module 5, is of vital importance for improving the overall performance, testing accuracy, and reliability of the device.

[0081] Please refer to this again. Figure 1 In one embodiment of this invention, the device innovatively adds a rotating platform 7 to the original structural system. This ingenious design provides richer testing methods for comprehensively and deeply evaluating the WIFI performance of the terminal 10.

[0082] From a structural layout perspective, the support base 2 is securely mounted on the rotary table 7. This structural design makes the support base 2 and the rotary table 7 form an organic whole, closely connected, and together provide a stable foundation platform for the placement and testing of the terminal 10.

[0083] The rotating platform 7 possesses a rotation function, which is its core feature. During the WIFI performance test, the rotating platform 7 can perform precise rotational movements according to a preset program or according to the instructions issued by the control module 5. When the rotating platform 7 starts to rotate, it will drive the support base 2 mounted on it to rotate together, and the terminal 10 on the support base 2 will also change its angle synchronously. Through this rotational action, the terminal 10 can adjust its angle during the test, thereby simulating the actual scenario of receiving WIFI signals in different directions and angles.

[0084] In practical testing applications, this angle adjustment function is of paramount importance. In real-world environments, the direction and angle at which the terminal 10 receives Wi-Fi signals vary greatly, and performance indicators such as signal strength, stability, and transmission rate may differ significantly under different directions and angles. For example, when the terminal 10 is directly facing the Wi-Fi signal source, the received signal strength may be strong and the transmission rate fast; however, when the terminal 10 deviates from a certain angle or faces away from the signal source, the signal strength may weaken, and the transmission rate may be affected. By using the rotating platform 7 to adjust the angle of the terminal 10, the device in this embodiment can comprehensively and systematically test the Wi-Fi performance of the terminal 10 under different directions and angles.

[0085] Specifically, during the test, the control module 5 can issue precise rotation commands to the rotary table 7 according to a preset test plan, controlling the rotary table 7 to rotate at specific angular intervals and speeds. For example, the rotary table 7 can be set to pause at certain angles (such as 10°, 15°, etc.). At each pause, the signal transmitting module 1 outputs a WiFi test signal according to the command of the control module 5. The terminal 10 receives the signal and performs corresponding data transmission. The monitoring module 6 and other related modules monitor and record various parameters during the test in real time. In this way, the device can acquire a series of WiFi performance data of the terminal 10 at different angles, such as signal strength, signal-to-noise ratio, and transmission rate.

[0086] This wealth of test data provides a solid foundation for a comprehensive evaluation of the Wi-Fi performance of Terminal 10. In-depth analysis and processing of this data allows for a precise understanding of the characteristics, strengths, and weaknesses of Terminal 10's Wi-Fi performance under different directions and angles, identifying potential performance bottlenecks and problems. For example, if a significant drop in signal reception performance is observed within a specific angle range, the cause can be further analyzed—whether it's due to an unreasonable antenna design, a flawed signal processing algorithm, or other factors. Based on these analytical results, manufacturers can make targeted improvements and optimizations to Terminal 10, enhancing the stability and reliability of its Wi-Fi performance, thereby improving the product's market competitiveness.

[0087] Furthermore, the design of the rotary table 7 embodies the high degree of automation and intelligence of the device in this embodiment. It can work collaboratively with other modules such as the control module 5, signal transmission module 1, and monitoring module 6 to achieve automated control and data acquisition during the testing process. Operators only need to set the corresponding test parameters and programs in the control module 5, and the device can automatically complete a series of test operations, including angle adjustment of the terminal 10, signal transmission, data reception, and monitoring, greatly improving testing efficiency and accuracy and reducing the interference of human factors on the test results.

[0088] In summary, in one embodiment of this invention, a rotating platform 7 is added, which drives the support base 2 and the terminal 10 to adjust their angles in order to test the WIFI performance of the terminal in different directions and angles.

[0089] Please refer to this again. Figure 1 and in conjunction with references Figure 3 In one embodiment of this invention, the signal transmitting module 1 includes a signal output unit 11, an attenuator 12, and an antenna 13.

[0090] The signal output unit 11 is used to generate a WiFi test signal;

[0091] From a functional and operational perspective, the signal output unit 11, as the source of the entire signal transmission module 1, is used to generate WiFi test signals. These initially generated WiFi test signals typically have relatively fixed strength and characteristics, providing the basic material for subsequent processing and testing.

[0092] Next, the generated WiFi test signal flows into the attenuator 12, which is electrically connected to it. The attenuator 12 attenuates the input WiFi test signal by adjusting its attenuation parameters to reduce the signal strength by a predetermined amount. This attenuation is not simply signal reduction, but rather highly precise and controllable. For example, in actual testing, the signal strength can be attenuated to a specific decibel value according to different testing requirements, thereby simulating weak signal environments that may be encountered in various real-world usage scenarios. Through the adjustment of the attenuator 12, the originally relatively fixed WiFi test signal is transformed into a series of signals with different strength levels, providing a rich sample of signals for subsequent comprehensive testing of the terminal's performance under different signal strengths.

[0093] Finally, the WiFi test signal processed by attenuator 12 is transmitted to antenna 13. Antenna 13, as the "transmitting terminal" of signal transmission module 1, is responsible for radiating the attenuated WiFi test signal into the surrounding space in the form of radio electromagnetic waves, so that terminal 10 placed on support base 2 can receive WiFi test signals of different strength levels.

[0094] In summary, the signal transmission module 1 adopts a combined structure of signal output unit 11, attenuator 12 and antenna 13. Through the coordinated work of each part, it realizes the generation, attenuation and radiation output of WiFi test signal, providing a reliable solution for comprehensively and accurately testing the WiFi performance of the terminal under different signal strengths.

[0095] Please refer to this again. Figure 1 In one embodiment of this invention, the device further includes a shielding box 8;

[0096] The signal transmitting module 1, the support base 2, the lifting mechanism 3, and the cover 4 are all located inside the shielding box 8.

[0097] It should be noted that in today's era of highly dense electronic devices and complex and ever-changing electromagnetic environments, various sources of electromagnetic interference exist, such as other wireless communication devices (mobile phones, Bluetooth devices, etc.), electronic and electrical equipment (computers, etc.), and natural electromagnetic phenomena (lightning, sunspot activity, etc.). These interference sources generate electromagnetic waves of different frequencies and intensities. If these electromagnetic waves enter the WIFI performance testing environment, they will severely interfere with the test signal, leading to deviations or even errors in the test results. The shielding box 8, through its special material and structural design, can effectively block the entry of external electromagnetic waves, providing a relatively independent electromagnetic space for the internal test equipment and terminal 10, isolating external interference, and ensuring that the testing process is not affected by the external electromagnetic environment.

[0098] Meanwhile, the shielding box 8 can also regulate and stabilize internal environmental parameters such as temperature and humidity. In some test scenarios with high environmental requirements, changes in temperature and humidity may affect the WIFI performance and signal transmission quality of the terminal 10. The shielding box 8 can, to a certain extent, block the influence of external environmental factors on the internal test environment, maintain the relative stability of the internal environment, and ensure that the test process is carried out under suitable environmental conditions, thereby improving the accuracy and repeatability of the test results.

[0099] In summary, by adding a shielding box 8 and housing the signal transmission module 1, support base 2, lifting mechanism 3, and cover 4 inside it, the shielding box provides a highly stable, clean, safe, and easily manageable testing environment for WIFI performance testing through its isolation, protection, and environmental stabilization functions. This is of great significance for improving the accuracy and reliability of test results and promoting the development of terminal WIFI technology.

[0100] Please refer to this again. Figure 1 In one embodiment of this invention, the device is additionally equipped with a temperature and humidity regulator 9.

[0101] The shielding box 8, as the core isolation and protection structure of the entire test environment, creates a relatively independent space for the various test components and terminal equipment inside, free from external electromagnetic interference. However, electromagnetic shielding alone is far from sufficient for some test scenarios with extremely stringent environmental requirements. As mentioned earlier, the WIFI performance of the terminal 10 is often significantly affected by environmental factors such as temperature and humidity. Under different temperature and humidity conditions, the electrical characteristics of the electronic components inside the terminal 10, the signal transmission quality, and the overall stability of the equipment will change to varying degrees. For example, in a high-temperature environment, electronic components may overheat, leading to performance degradation or even malfunction; while in a high-humidity environment, moisture may penetrate the equipment, causing serious problems such as short circuits, thereby affecting the accuracy and reliability of the test results.

[0102] The addition of the temperature and humidity regulator 9 is precisely to effectively solve the above-mentioned problems. It has temperature and humidity regulation capabilities, and can adjust the temperature and humidity inside the shielding box 8 in real time and precisely according to preset parameters. Through its advanced internal sensor system, the temperature and humidity regulator 9 can sense the temperature and humidity changes inside the shielding box 8 in real time and quickly issue corresponding adjustment commands, driving the internal heating, cooling, humidification, or dehumidification devices to operate, thereby ensuring that the inside of the shielding box 8 always maintains a stable state of constant temperature and humidity.

[0103] In summary, by adding a temperature and humidity regulator 9 and placing it on the shielded box 8, the temperature and humidity inside the shielded box 8 can be precisely adjusted to maintain a constant temperature and humidity state. This provides a highly stable and reliable environment for WIFI performance testing, which plays an important role in improving the accuracy and reliability of the test results.

[0104] Although this invention frequently uses terms such as transmitting module, support base, and lifting mechanism, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.

[0105] Example 2

[0106] Please refer to Figure 4 This is a flowchart illustrating a WIFI performance testing method according to Embodiment 2 of the present invention. This method is applicable to scenarios where the WIFI performance of a terminal is tested, and it is implemented using the WIFI performance testing device provided in Embodiment 1 above. The method specifically includes the following steps:

[0107] S101. The signal transmitting module is used to output a WiFi test signal.

[0108] It should be noted that at the beginning of the WiFi performance test, the signal transmission module can accurately output WiFi test signals according to pre-set parameters and standards. These test signals cover a variety of key indicators, including but not limited to different signal frequencies, signal strengths, and modulation methods.

[0109] The WiFi test signal output by the signal transmission module provides the fundamental data source for subsequent testing, serving as the starting point and crucial step in the entire WiFi performance testing process. Only by ensuring the accuracy and diversity of the test signals can a reliable basis be provided for a comprehensive evaluation of the terminal's WiFi performance.

[0110] S102. The lifting mechanism is used to lower the cover to get closer to the support base.

[0111] It should be noted that after outputting the WiFi test signal, the next step is to build the test environment. The lifting mechanism then comes into play, precisely controlling the raising and lowering of the cover. In this step, the lifting mechanism slowly lowers the cover, gradually bringing it closer to the support base.

[0112] The support base in the testing device serves to support and position the terminal, ensuring its stable position and posture during testing. The descent of the cover, however, has multiple important implications. The descent process dynamically adjusts the testing environment. By controlling the speed and final position of the cover's descent, different testing scenarios can be simulated. For example, when the cover descends to close with the support base, it simulates communication within a relatively small, enclosed space, such as placing the terminal inside a metal chassis or a closed room. When the cover descends to a certain height, leaving a gap with the support base, it simulates communication in open or semi-open spaces. This ability to dynamically adjust the testing environment allows this testing method to more comprehensively evaluate the terminal's Wi-Fi performance in different real-world scenarios.

[0113] S103. During the process of the cover approaching the support base, the control module receives test data sent by the terminal to be tested and generates WiFi test results.

[0114] It should be noted that after receiving the WiFi test signal output by the signal transmitting module, the terminal under test will receive, demodulate, and process the signal according to its own WiFi performance and processing capabilities. During this process, the terminal will collect a series of WiFi performance-related data, such as RSSI (Signal Strength Indicator), data transmission rate, packet loss rate, and bit error rate. These data are key indicators for evaluating the terminal's WiFi performance.

[0115] The control module receives test data sent by the terminal in real time through a communication connection. During the data reception process, the control module performs preliminary screening and organization to ensure the integrity and accuracy of the data. For example, the control module checks whether the received data is complete, whether there is any data loss or error, and marks incomplete or erroneous data or requests the terminal to resend it.

[0116] After receiving complete and accurate test data, the control module uses pre-set algorithms and models to perform in-depth analysis and processing of this data. These algorithms and models are based on a large amount of experimental data and theoretical research results, and can provide a comprehensive and objective evaluation of the terminal's WIFI performance.

[0117] Finally, the control module generates a detailed WiFi test results report based on the data analysis. This report presents the terminal's WiFi performance in an intuitive and easy-to-understand way, using a combination of charts, graphs, and text descriptions to clearly demonstrate the terminal's performance across various performance indicators. Simultaneously, the report provides a comprehensive evaluation of the terminal's WiFi performance, giving a corresponding score or rating, offering users a comprehensive reference for understanding the terminal's WiFi performance.

[0118] In summary, the WIFI performance testing method provided in Embodiment 1 of this invention forms a complete and rigorous testing process through a series of steps, including the signal transmitting module outputting a WIFI test signal, the lifting mechanism lowering the cover to create a test environment, and the control module receiving test data and generating test results. This method can comprehensively and accurately evaluate the WIFI performance of a terminal, providing strong technical support for the research and development, production, and quality testing of terminals.

[0119] Please refer to Figure 5 In one embodiment of this example, in Figure 4 Based on this, S101 can be further refined into the following steps:

[0120] S1011. The signal transmitting module is used to output the attenuated WiFi test signal.

[0121] It's important to note that the attenuation processing is primarily designed to simulate various complex signal environments that a terminal might encounter during actual use. In real-world scenarios, the WiFi signal strength received by a terminal is not always ideal; it is affected by multiple factors and attenuates. For example, as the distance between the terminal and the signal source (such as a router) increases, the signal gradually weakens during propagation—a typical example of distance attenuation. When obstacles (such as walls or furniture) exist between the terminal and the signal source, the signal experiences additional attenuation due to obstruction and absorption. The degree of attenuation varies depending on the material and thickness of the obstacle. Furthermore, in complex electromagnetic environments with multiple wireless signal sources, different signals may interfere with each other, leading to a decrease in signal quality—another form of indirect signal attenuation.

[0122] To more realistically simulate these actual signal environments, the signal transmission module attenuates the output WiFi test signal. This is achieved by introducing an attenuator into the signal transmission path or utilizing the signal transmission module's own attenuation control function to precisely adjust the signal strength according to pre-set attenuation parameters. These attenuation parameters can be flexibly set according to actual testing needs; for example, different attenuation levels (in dB) can be set to simulate varying degrees of signal attenuation, thereby generating a series of attenuated WiFi test signals with different strength levels.

[0123] In summary, by simulating actual signal attenuation, a more realistic and comprehensive signal environment is provided for WIFI performance testing, which helps to gain a deeper understanding of the terminal's performance under different signal strength conditions.

[0124] Please refer to Figure 6 In one embodiment of this example, step S103 can be further refined into the following steps:

[0125] S1031. The control module receives test data sent by the terminal to be tested during the process of the cover approaching the support base.

[0126] S1032. Calculate the deviation value based on the test data and the following formula:

[0127] ;

[0128] ;

[0129] in, for Ideal carrier frequency at all times for The original carrier frequency at any given time. for The frequency of electromagnetic interference at any given time. Carrier ratio, for Deviation value at time, for The transmission frequency at any given moment.

[0130] It should be noted that after receiving complete and accurate test data, the control module will use the specific formula mentioned above to perform in-depth calculations on this data to derive the deviation value. This step is the core calculation in the entire testing process and plays a crucial role in accurately evaluating the terminal's Wi-Fi performance.

[0131] The magnitude of the deviation value directly reflects the degree to which the terminal is affected by various factors (such as interference, signal attenuation, etc.) during the reception and processing of WiFi signals. For example, a large deviation value indicates that the terminal may encounter serious signal instability problems in actual use, leading to an increased probability of data transmission errors or interruptions; while a small deviation value indicates that the terminal's WiFi signal stability is good, and it can maintain relatively accurate data transmission in complex environments.

[0132] S1033. Generate WiFi test results based on the deviation value.

[0133] It should be noted that after calculating the deviation values, the control module will generate detailed WiFi test results based on these deviation values. This step is a data summary and comprehensive evaluation of the entire testing process, providing users with comprehensive and intuitive information on the terminal's WiFi performance.

[0134] Specifically, the control module analyzes the calculated deviation value. It compares the deviation value with a pre-set threshold range to determine whether the terminal's Wi-Fi performance is within the normal range. If the deviation value exceeds the threshold range, it indicates that the terminal may have a performance problem and requires further in-depth analysis. For example, if the deviation value is consistently large and fluctuates frequently, it may indicate that the terminal has weak anti-interference capabilities and is easily affected by external electromagnetic interference; if the deviation value shows abnormal changes within a specific time period, it may be related to hardware failure or software algorithm defects in the terminal.

[0135] In summary, step S103 is broken down into three steps: S1031 receiving test data, S1032 calculating deviation values, and S1033 generating test results. Through data reception and scientific calculation and analysis, accurate and detailed WiFi test results can be generated, providing strong technical support for terminal research and development, production, and quality testing.
