[0002] With the rapid development of technology, wireless network technologies have been widely applied and are an indispensable part of people's production and life.

[0003] Currently, with the increasing upgrade of usage requirements, a Mesh function for WiFi (Wireless Fidelity) products has received wide attention. The Mesh function connects multiple routers or nodes in a mesh structure to form a dynamic network architecture, where any two devices can maintain wireless interconnection. In the existing open environment, it is impossible to achieve networking and performance testing between MESH nodes, and it is also impossible to implement a roaming function test for client devices based on the strength of wireless signals. However, for MESH routers, it is particularly important to ensure the forward and return transmission performance between various networking methods and nodes.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0045] The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings, specific embodiments, and their application scenarios.

[0046] Embodiment 1

[0047] Figure 1 It is a schematic diagram of the structure of a wireless AP Mesh networking function and performance testing system provided by Embodiment 1 of the present application. As Figure 1 shown, it specifically includes:

[0048] At least four wireless access points 110, one client device 120, and a shielding box; the wireless access points 110 and the client device 120 are respectively placed in the shielding box;

[0049] The shielding boxes are connected by RF cables, which respectively include a transmitting line and a return line, so that the shielding boxes where each wireless access point is located are respectively connected to the shielding box where the client device is located; a wireless signal separation and controller 130 is provided between the mutually connected shielding boxes;

[0050] The wireless signal separation and controller 130 is used to separate and adjust the signal strength between each wireless access point 110 and the signal strength transmitted to the client device 120, and adjust the signal strength returned by the client device 120 to each wireless access point 110;

[0051] The client device 120 is used to record the signal strength of each wireless access point 110 and the roaming data between each wireless access point 110.

[0052] The wireless access point 110 and the client 120 are connected to the external measurement PCs 1-PC5 through network cables via filters provided on the shielding box

[0053] Among them, the wireless access point 110 is a Mesh node. The Mesh function connects multiple routers or nodes in a mesh structure to form a dynamic network architecture, where any two devices can maintain wireless interconnection. This technology solves the problems of traditional wireless networks in terms of coverage and stability. Especially in a home environment, when the signal of a single router cannot cover all corners, the Mesh network can provide an effective solution. By adding additional Mesh nodes, an optimal network environment can be automatically constructed according to the house type and placement location, ensuring that devices in the network can obtain excellent signal coverage anywhere. In addition, the Mesh network also has the ability of self-healing. Even if one of the nodes fails, the network can automatically re-establish the optimal network environment, ensuring the reliability and stability of the network.

[0054] In this solution, the number of wireless access points 110 can be two or more, Figure 1 and four are taken as an example for introduction. In addition, the wireless access point 110 can include a master node and slave nodes. For example, one of them can be the master node and the other can be the slave node. In addition, in the case of more wireless access points 110, one master node and multiple slave nodes can be set. At the same time, in the case of multiple nodes, the nodes can be networked in different topological structures, such as Figures 6 to 9 .

[0055] The wireless signal separation and controller 130 can be adjusted by a control signal or manually. For example, in the control unit of the wireless AP Mesh networking function and performance test system, a control signal can be sent to the wireless signal separation and controller 130. For example, if the signal strength of the original wireless access point 110 is 100%, its signal strength can be adjusted to 50% or 30% etc. by the wireless signal separation and controller 130. The signal strength returned by the client device 120 to each wireless access point 110 can also be adjusted. For example, if the signal strengths originally returned to each wireless access point 110 are 50% and 40% respectively, they can be adjusted to 40% and 20% by the controller 130.

[0056] The embodiment of the present application provides a wireless AP Mesh networking function and performance test system,

[0057] In one embodiment, optionally, a wireless signal separation and controller is further provided between the interconnected shielding boxes;

[0058] The wireless signal separation and controller is used to perform frequency band separation when the signal transmitted by the wireless access point is a combined signal;

[0059] The wireless signal separation and controller is used to adjust the signal strength of the signal in the frequency band where the received signal of the client device is located.

[0060] The combined signal can refer to signals with at least two frequency bands. For example, any two signals between 2G, 5G, and 6G put together can be called a combined signal. It can be understood that putting all three signals together, or adding signals with more frequency bands, can also be used as a combined signal.

[0061] With this setting in this embodiment, the wireless signal separation and controller can be used to distinguish signals in each frequency band, so as to realize independent control of the backhaul and access signals, and can realize independent testing of the backhaul and access channels.

[0062] In one embodiment, optionally, a coupling antenna is provided inside the shielding box;

[0063] The RF cable is connected to the coupling antennas of the two shielding boxes. A coupling antenna is a type of antenna that realizes signal transmission and reception through electromagnetic coupling. The coupling antenna utilizes the near-field coupling effect to couple the energy of one antenna to another antenna. It usually consists of two or more antenna elements, where one antenna acts as the transmitting antenna and the other as the receiving antenna. When the transmitting antenna emits electromagnetic waves, the generated electromagnetic field will induce a current in the nearby receiving antenna, thus realizing signal transmission. The coupling antenna has the characteristics of high isolation. Due to the use of the coupling method, a relatively high isolation degree can be achieved between the transmitting and receiving antennas, reducing mutual interference. Miniaturization: It can be designed to be relatively compact and is suitable for application scenarios with limited space. The coupling antenna has the characteristic of high flexibility. By adjusting the structure and parameters of the antenna, different frequency responses and radiation characteristics can be achieved. The application scenarios of coupling antennas are relatively wide. For example, in wireless communication, in fields such as mobile communication, Bluetooth, and wireless local area networks, coupling antennas can improve the signal transmission quality and coverage. Radio frequency identification (RFID), used for communication between tags and readers to realize automatic identification and tracking of items. Sensor networks, as the antennas of sensor nodes to realize wireless data transmission. Satellite communication, in satellite communication systems, coupling antennas can improve the signal reception sensitivity and anti-interference ability.

[0064] In this embodiment, by using the coupling antenna, signals can be provided to the client device, so that the client device can receive the signals emitted by each wireless access point through the receiving antenna, simulating a real usage scenario, making the wireless AP Mesh networking function and performance testing more in line with the real usage scenario.

[0065] In one embodiment, optionally, the wireless signal separation and controller is used for separating and controlling 2G, 5G, and 6G signals.

[0066] The wireless signal separator and controller separates the input mixed signal by using technical means such as filters, taking advantage of the characteristic differences of signals with different frequencies. For 2G, 5G, and 6G signals, since they each have specific frequency ranges, the filters in the separator can perform selective filtering based on frequency, allowing signals within a specific frequency range to pass through while blocking signals of other frequencies, thus achieving signal separation.

[0067] Specifically, hardware design can be adopted, using high-performance electronic components such as filters and amplifiers to construct a reliable signal separation circuit. When designing, the characteristics of signals in different frequency bands need to be considered to ensure that the selectivity, passband, and stopband characteristics of the filter meet the requirements. Software control, combined with digital signal processing technology, further processes and controls the separated signals through software algorithms. For example, operations such as signal enhancement and noise reduction can be performed on the signals to improve signal quality. And in ways such as adaptive adjustment, as the communication environment changes, the characteristics of the signals may also change. Therefore, the wireless signal separator and controller can adopt adaptive technology to automatically adjust the separation parameters according to the real-time signal conditions to ensure the stability and reliability of the separation effect.

[0068] The separation and control of 2G, 5G, and 6G signals by the wireless signal separator and controller is a key link in achieving efficient communication and optimizing system performance. Through reasonable design and control, the advantages of signals in different frequency bands can be fully utilized to provide better communication services for various applications.

[0069] In one embodiment, optionally, the system further includes: a switching switch:

[0070] The switching switch is used to connect the signal to the wireless signal separator and controller when the signal transmitted by the wireless access point is a combined signal; and connect the signal to the short-circuit route of the wireless signal separator and controller when the signal transmitted by the wireless access point is a single-band signal.

[0071] Among them, the switching switch can be used to perform gating control on the signals sent by the wireless access point. For example, if the signal sent by the wireless access point is a single-band signal, it can be directly connected to the short-circuit route of the wireless signal separator and controller without the need to connect to the wireless signal separator and controller. If it is a combined signal, it needs to be connected to the wireless signal separator and controller for signal separation processing.

[0072] In this embodiment, by setting the switching switch, the access circuit of the signal can be better and reasonably controlled, improving the controllability of signal data during the wireless AP Mesh networking function and performance testing process.

[0073] This facility records the data throughput performance between each AP under test and the accompanying test client by running traffic with iperf installed in the test PC.

[0074] By adjusting the wireless signal separation and controller, the data throughput performance at different frequency bands and simulating different distances can be independently tested.

[0075] In Figures 6 to 9 different networking modes, the data throughput performance of different frequency bands between different nodes in different modes is tested respectively.

[0076] The attenuation value of the access frequency band can be independently adjusted, and the distances between each AP and between the accompanying test clients can be simulated to achieve the purpose of topological transformation of MESH networking and client roaming.

[0077] Since the access and backhaul frequency bands can be independently controlled, adjusting the access attenuation does not affect the backhaul data performance, thus enabling independent testing of access and backhaul.

[0078] Among them, the wireless access point is a Mesh node. The Mesh function connects multiple routers or nodes in a mesh structure to form a dynamic network architecture, where any two devices can maintain wireless interconnection. This technology solves the problems of traditional wireless networks in terms of coverage and stability. Especially in a home environment, when the signal of a single router cannot cover all corners, the Mesh network can provide an effective solution. By adding additional Mesh nodes, the optimal network environment can be automatically constructed according to the house type and placement location, ensuring that devices in the network can obtain excellent signal coverage at any location. In addition, the Mesh network also has the ability of self-healing. Even if one of the nodes fails, the network can automatically re-establish the optimal network environment, ensuring the reliability and stability of the network.

[0079] In this solution, the number of wireless access points can be two or more, and four are taken as an example for introduction. In addition, the wireless access point can include a master node and slave nodes. For example, one of them can be the master node and the other can be the slave node. In addition, in the case of more wireless access points, one master node and multiple slave nodes can be set. At the same time, in the case of multiple nodes, the nodes can be networked in different topological structures.

[0080] The configuration process of the Mesh network is also relatively simple. Adding new Mesh nodes and modifying network settings are very convenient. Modifying the master node information will automatically synchronize other routers in the entire Mesh network. For newly added nodes, there is no need to set information such as SSID, password, and upstream router. After being powered on, it will automatically synchronize and automatically form a network. This technology is not only suitable for novice users but also suitable for professional environments that require large-area coverage and high stability.

[0081] The Mesh function improves the coverage and stability of wireless networks by constructing a dynamic and scalable network architecture, and simplifies the network configuration process at the same time. It is an ideal solution to solve the wireless network coverage problem.

[0082] The shielding box can be an electromagnetic shielding box that can shield electromagnetic signals. The client device 120 can be a device capable of connecting to a wireless network, such as a smartphone, a tablet computer, etc. The RF cable can be used to transmit the network signal emitted by the wireless access point.

[0083] The wireless signal separator and controller can be adjusted by a control signal or manually adjusted. For example, in the control unit of the wireless AP Mesh networking function and performance test system, a control signal can be sent to the wireless signal separator and controller. For example, if the original signal strength of the wireless access point is 100%, its signal strength can be adjusted to 50% or 30% etc. by the wireless signal separator and controller. The signal strength returned by the client device to each wireless access point can also be adjusted. For example, if the signal strengths originally returned to each wireless access point are 50% and 40% respectively, they can be adjusted to 40% and 20% by the wireless signal separator and controller.

[0084] The client device can receive wireless signals inside the shielding box, record the signal strengths of each wireless access point, and record the roaming data between each wireless access point.

[0085] For example, the signal strength of wireless access point A is 20%, the signal strength of wireless access point B is 30%, the signal strength of wireless access point C is 50%, and the initial signal strengths of each wireless access point are the same. Then the client device connects to wireless access point C. If later, the signal strength of wireless access point A is adjusted from 20% to 80%, the client device will roam to wireless access point A. If no roaming occurs at this time, it is determined that the wireless AP Mesh networking function and performance test fails.

[0086] The embodiment of the present application provides a wireless AP Mesh networking function and performance test system.

[0087] In one embodiment, optionally, a wireless signal separator and controller is also provided between the interconnected shielding boxes;

[0088] The wireless signal separator and controller is used to perform frequency band separation when the signal emitted by the wireless access point is a combined signal;

[0089] The wireless signal separator and controller is used to adjust the signal strength of the frequency band where the received signal of the client device is located.

[0090] The combined signal can refer to signals with at least two frequency bands. For example, any two signals among 2G, 5G, and 6G put together can be called a combined signal. It can be understood that putting all three signals together, or adding signals with more frequency bands, can also be regarded as a combined signal.

[0091] With this setting in this embodiment, the wireless signal separation and the controller can be used to distinguish signals of each frequency band, thereby realizing independent control of the backhaul and access signals, and enabling independent testing of the backhaul and access channels.

[0092] In one embodiment, optionally, a coupling antenna is provided inside the shielding box;

[0093] The RF cable is connected to the coupling antennas of the two shielding boxes. A coupling antenna is a type of antenna that realizes signal transmission and reception through electromagnetic coupling. The coupling antenna utilizes the near-field coupling effect to couple the energy of one antenna to another antenna. It usually consists of two or more antenna elements, where one antenna serves as the transmitting antenna and the other as the receiving antenna.

The coupling antenna has the characteristics of high isolation. Due to the use of the coupling method, a relatively high isolation degree can be achieved between the transmitting and receiving antennas, reducing mutual interference. Miniaturization: It can be designed to be relatively compact and is suitable for application scenarios with limited space. The coupling antenna has the characteristic of high flexibility.

[0094] In this embodiment, by using the coupling antenna, the signal can be provided to the client device, enabling the client device to receive the signals transmitted by each wireless access point through the receiving antenna, simulating a real usage scenario, and making the wireless AP Mesh networking function and performance testing more in line with the real usage scenario.

[0095] In one embodiment, optionally, the wireless signal separation and controller are used to separate and control 2G, 5G, and 6G signals.

[0096] The wireless signal separator and controller separates the input mixed signal by using technical means such as filters, taking advantage of the characteristic differences of signals with different frequencies. For 2G, 5G, and 6G signals, since they each have specific frequency ranges, the filters in the separator can perform selective filtering according to the frequency, allowing signals within a specific frequency range to pass through while blocking signals of other frequencies, thereby achieving signal separation.

And through adaptive adjustment, etc., as the communication environment changes, the characteristics of the signal may also change. Therefore, the wireless signal separator and controller can adopt adaptive technology to automatically adjust the separation parameters according to the real-time signal conditions to ensure the stability and reliability of the separation effect.

Through reasonable design and control, the advantages of signals in different frequency bands can be fully utilized to provide better communication services for various applications.

[0099] In one embodiment, optionally, the system further includes: a switching switch:

[0100] The switching switch is used to connect the signal to the wireless signal separator and controller when the signal transmitted by the wireless access point is a combined signal; and connect the signal to the short-circuit line of the wireless signal separator and controller when the signal transmitted by the wireless access point is a single-band signal.

For example, if the signal sent by the wireless access point is a single-band signal, it can be directly connected to the short-circuit line of the wireless signal separator and controller without the need to access the wireless signal separator and controller. If it is a combined signal, it needs to be connected to the wireless signal separator and controller for signal separation processing.

[0102] In this embodiment, by setting the switching switch, the access circuit of the signal can be better and reasonably controlled, improving the controllability of the signal data during the wireless AP Mesh networking function and performance testing process.

[0103] In one embodiment, optionally, the system further includes:

[0104] A test device for receiving the signal strength and roaming data of each recorded wireless access point sent by the client device;

[0105] The test device is further configured to generate a test report based on the signal strength of each wireless access point and the roaming data.

[0106] In this solution, based on the signal strength and roaming data of each recorded wireless access point, it can be determined whether the occurrence time of roaming and the target wireless access point actually roamed to are reasonable. If it is reasonable, it is determined that the test passes; if it is not reasonable, it is determined that the wireless AP Mesh networking function and performance test fails.

[0107] Figure 2 It is a schematic diagram of the wireless AP Mesh networking function and performance test provided in the first embodiment of this application. As Figure 2 shown, AP-DUT represents the main node under test, EXT-DUT represents the branch node under test, and STA (Station) represents the client device.

[0108] This solution provides a test method for the Mesh function and performance of WiFi products. In the existing open environment, it is impossible to implement the roaming function test between different APs by controlling the strength of the controllable wireless signal of the client device. The main reason is that it is impossible to control the signal strength of each AP received by the STA and the interference of other wireless signals. This method places the test AP and STA in a shielding box, and externally uses a radio frequency cable to connect through a wireless signal separator and a controller. Inside the shielding box, signal transmission between shielding boxes is achieved through antenna coupling. By adjusting the attenuation, the wireless signal strength of each AP reaching the STA is controlled, simulating different distances between the STA and each AP, so as to realize the function of the STA roaming between different APs.

[0109] Figure 3 It is a schematic diagram of the radio frequency signal separation control provided in the first embodiment of this application. As Figure 3 shown, this method first uses an electromagnetic shielding box to check the interference of external wireless signals on the test process. The shielding boxes are connected in series through a radio frequency cable with a wireless signal separator and a controller. This not only ensures the anti-interference performance against external signals but also enables mutual visibility between the boxes. By adjusting the attenuator, the strength of the signal is controlled to achieve the effect of simulating the distance between devices. In dual-band or even tri-band WiFi Mesh networking, usually different frequency bands are used for backhaul and access. However, the antennas of AP products are usually used in a combined way. Therefore, in the connection network between shielding boxes, a radio frequency wireless signal separator and a controller are required to achieve the separation control of 2G, 5G, and 6G signals. Then, the strength of different frequency band signals is independently controlled through the attenuator, so as to achieve the independent control of backhaul and access signals and realize the independent test of backhaul and access channels.

[0110] The embodiments of the present application provide a wireless AP Mesh networking function and performance testing solution, which can make the backhaul access channel independently controllable, enable the testing of complex multi-hop Mesh environments, and the test results are repeatable.

[0114] Step S402: Adjust the signal strength between each wireless access point and the signal strength transmitted to the client device through a wireless signal separator and controller, and adjust the signal strength returned by the client device to each wireless access point;

[0115] Step S403: Record the signal strength of each wireless access point through the client device, and record the roaming data between each wireless access point.

[0116] Further, after recording the signal strength of each wireless access point through the client device and recording the roaming data between each wireless access point, the method further includes:

[0117] Receive the signal strength and roaming data of each wireless access point recorded and sent by the client device through a test device, and generate a test report based on the signal strength of each wireless access point and the roaming data.

[0118] This solution transmits signals through a wireless access point; adjusts the signal strength between each wireless access point and the signal strength transmitted to the client device through a wireless signal separator and controller, and adjusts the signal strength returned by the client device to each wireless access point; records the signal strength of each wireless access point through the client device, and records the roaming data between each wireless access point. With the function of the shielding box, this technical solution removes the mutual interference between multiple signals. Under the condition of adjustment through a wireless signal separator and controller, it can simulate the change in the distance between the client device and the wireless access point, so that the client device can receive signals with different signal strengths, and thus realize roaming between multiple wireless access points. In this way, this solution realizes the testing of the wireless AP Mesh networking function and performance. The test data is accurate and scientific, providing a good evaluation basis for roaming rationality.
