Description

Technical Field

[0001] This invention relates to the field of wireless network technology, and in particular to a method and system for recreating a Wi-Fi scene in a laboratory setting. Background Technology

[0002] With the development of wireless network technology, people's lives have become deeply intertwined with Wi-Fi. In response to the growing demand, industries such as the Internet of Things (IoT), artificial intelligence (AI), smart homes, big data, and edge computing have sprung up rapidly, advancing towards the concept of the Internet of Everything. This has spurred a surge in the number of devices requiring internet connectivity. Wi-Fi, due to its superior transmission capabilities and convenient deployment, has quickly captured the top spot in the market. Consequently, the complexity of the internet has also increased dramatically, making thorough testing of Wi-Fi devices and apps utilizing them particularly crucial. Currently, the testing conducted by major manufacturers in the laboratory stage can only be done in simple and clean laboratory environments consisting of one or a few access points (APs), making it difficult to discover and expose problems in the relatively complex internet environment.

[0003] Furthermore, if scenario data captured during comprehensive testing is not processed before being played back to the shielded room, inconsistent results will be found each time, failing to effectively reproduce the scenario. Typically, testing of devices or apps under complex network conditions is conducted during the overall testing phase before mass production or even after release, reviewed and resolved through customer service issues. This approach has two drawbacks: firstly, it consumes excessive human resources, testing time, and development costs; secondly, customers may encounter problems during use, inadvertently leading to comparisons with competitors, potentially reducing customer satisfaction and brand reputation. Summary of the Invention

[0004] This invention provides a laboratory-based Wi-Fi scene reconstruction method to overcome the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A method for recreating a Wi-Fi scenario in a laboratory setting includes the following steps:

[0007] Step S1: Establish the real Wi-Fi scenario environment to be collected using several AP devices; each AP device is equipped with several working channels that provide signaling.

[0008] Step S2: The data acquisition unit acquires signaling for the specified working channel, obtains and saves the signaling dataset; and the data acquisition unit sends the signaling in the signaling dataset to the simulation restoration processing unit.

[0009] Step S3: The simulation restoration processing unit filters the acquired signaling;

[0010] The filtered signaling is then transmitted to the shielded room; and the shielded room is equipped with a data transmission unit, a signal strength management unit, and an antenna unit that are connected in sequence.

[0011] Step S4: The data transmission unit groups and sorts the filtered signaling into different signal strength classification pools according to different signal strengths;

[0012] Furthermore, each of the aforementioned signal strength classification pools is equipped with a signaling transmission device;

[0013] The signaling transmission device sends the signaling from the signal strength classification pool to the signal strength management unit;

[0014] Step S5: The signal strength management unit transmits the signaling in the signal strength classification pool through their respective unique communication channels according to the frame information of the signaling; the frame information of the signaling includes timestamp, frame type and data length;

[0015] The signal strength of the signaling in each of the communication channels is adjusted to a preset strength and then sent to the antenna unit connected to the communication channel.

[0016] Step S6: The antenna unit sends the signal strength adjusted signal to the shielded room according to the timing of receiving the communication channel signal, so as to obtain the wireless network environment of the Wi-Fi scene reconstruction.

[0017] Furthermore, the step S2, which involves acquiring signaling for a specified working channel via a data acquisition unit, specifically involves...

[0018] Using packet capture tools, the AP devices in the real Wi-Fi scenario environment to be collected are scanned for a specified working channel to obtain IEEE 802.11 protocol layer signaling;

[0019] The packet capture tool can collect data from all specified working channels within the scope of the IEEE 802.11 protocol, and supports only one working channel at a time.

[0020] The packet capture tools include, but are not limited to, Wireshark, Fiddler, and Sniffer.

[0021] Furthermore, the simulation restoration processing unit in step S3 filters the acquired signaling, specifically by:

[0022] Step S3.1: Read the signaling dataset acquired by the data acquisition unit;

[0023] The signaling dataset is type data collected within the scope specified by the IEEE 802.11 protocol; the type data includes, but is not limited to, Wi-Fi network parameters, signal strength, packet size, data latency, and data packets;

[0025] Furthermore, the data frame includes the data packet rate, signal strength, and transmission power;

[0026] The filtered signaling frames include Beacon frames, Probe Request frames, Probe Response frames, Authentication frames, and Disassociation frames.

[0028] The signaling data to be simulated includes the AP device identification keyword in the signaling, as well as the signaling length, timestamp, and signal strength;

[0029] Step S3.4: Send the signaling data to be simulated to the data transmission unit.

[0030] Furthermore, in step S4, the filtered signaling is grouped and organized according to different signal strengths.

[0031] The grouping method involves sorting the signal strength values ​​in descending order and dividing the signaling of different signal strengths into strong, medium, weak, and extremely weak categories based on a set strength signal division threshold.

[0032] The formula for calculating the signal strength is as follows:

[0033] Signal Strength(dBm)=10log10(Pout / Pin)+Gtx+Grx-PL

[0034] In the formula: Signal Strength represents signal strength; Pout represents signal transmit power; Pin represents signal receive power; Gtx represents the gain of the transmit antenna; Grx represents the gain of the receive antenna; PL represents the path loss of signal transmission.

[0036] The AP device is used to establish a Wi-Fi network environment at a preset location;

[0037] The data acquisition unit is used to scan the surrounding Wi-Fi network environment, collect the signaling of the designated working channel of the AP device, and transmit it to the simulation restoration processing unit;

[0038] The simulation restoration processing unit communicates with the data acquisition unit and the data transmission unit, respectively.

[0039] Furthermore, the simulation restoration processing unit is used to filter the signaling acquired by the data acquisition unit and transmit the filtered signaling to the data transmission unit.

[0040] The data transmission unit is used to organize signaling groups of different signal strengths into different signal strength classification pools, and send the organized signaling groups to the signal strength management unit through the signaling transmission device.

[0041] The signaling strength management unit is used to provide several communication channels for signaling signal strength adjustment, and the signaling strength management unit is connected to the antenna unit through the communication channels;

[0042] The antenna unit is used to transmit signaling with adjusted signal strength to the shielded room.

[0043] Furthermore, the data transmission unit includes one or more electronic devices capable of transmitting Wi-Fi communication signaling data;

[0044] The electronic device includes a communication antenna, a processor, and a memory; and the memory stores a programming program for execution by the processor.

[0045] Furthermore, the signal strength management unit includes an attenuator with several communication channels;

[0046] Furthermore, each pair of any two adjacent communication channels is matched with a signal strength classification pool, and the signal strength adjustment is the same for communication channels that are matched with any signal strength classification pool.

[0047] Beneficial Effects: This invention provides a method and system for recreating a Wi-Fi scenario in a laboratory setting. A data acquisition unit collects signaling from a specified working channel, and a simulation restoration processing unit filters the collected signaling. A data transmission unit groups and organizes the filtered signaling according to different signal strengths. A signal strength management unit uses its communication channel to acquire signaling simulating different signal strengths, extracting the timestamp, frame type, and data length of the Wi-Fi scenario signaling. An antenna unit then transmits the signaling of different signal strengths to the shielded room to obtain the wireless network environment.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0053] This embodiment provides a method for recreating a Wi-Fi scenario in a laboratory setting, such as... Figure 1 As shown, it includes the following steps:

[0054] Step S1: Establish the real Wi-Fi scene environment to be collected using several AP devices; the real Wi-Fi scene environment to be collected is, for example, a real scene of a 120㎡ three-bedroom apartment, and the coverage area of ​​the Wi-Fi currently in use in the living room; the AP devices are equipped with several working channels that provide signaling;

[0055] Step S2: The data acquisition unit collects signaling for the specified working channel, obtains and saves the signaling dataset; and the data acquisition unit sends the signaling in the signaling dataset to the simulation and restoration processing unit; and the working channel of Wi-Fi can be set on the router management page. The number and naming of channels vary from router to router model.

[0056] Step S3: The simulation restoration processing unit filters the acquired signaling;

[0057] The filtered signaling is then transmitted to the shielded room; and the shielded room is equipped with a data transmission unit, a signal strength management unit, and an antenna unit that are connected in sequence.

[0058] Step S4: The data transmission unit groups and sorts the filtered signaling into different signal strength classification pools according to different signal strengths;

[0059] Furthermore, each of the aforementioned signal strength classification pools is equipped with a signaling transmission device;

[0060] The signaling transmission device sends the signaling from the signal strength classification pool to the signal strength management unit;

[0061] Step S5: The signal strength management unit transmits the signaling in the signal strength classification pool through their respective unique communication channels according to the frame information of the signaling; the frame information of the signaling includes timestamp, frame type and data length;

[0062] The signal strength of the signaling in each of the communication channels is adjusted to a preset strength and then sent to the antenna unit connected to the communication channel.

[0063] Step S6: The antenna unit sends the signal strength adjusted signal to the shielded room in the laboratory according to the timing of receiving the communication channel signal, so as to obtain the wireless network environment of the Wi-Fi scenario.

[0064] The signaling of a designated working channel is acquired by a data acquisition unit, and filtered by a simulation restoration processing unit. The filtered signaling is then grouped and organized by a data transmission unit according to different signal strengths. The signal strength management unit uses its communication channel to acquire signaling simulating different signal strengths, extracting the timestamp, frame type, and data length of the Wi-Fi scenario signaling. This signaling is then transmitted to the shielded room via an antenna unit to obtain the wireless network environment. This allows for accurate and effective restoration of the wireless network environment within the shielded room compared to the real Wi-Fi scenario, ultimately achieving a high degree of simulation of complex environments in the laboratory. This enables testing of Wi-Fi devices or game apps under different network environments in the laboratory, effectively improving the efficiency of Wi-Fi-related testing, shortening testing time, reducing costs, and making test results more accurate. The specific testing under different network environments includes:

[0065] Extreme network environment: This involves collecting signaling data between the device and the Wi-Fi network at the edge of the Wi-Fi coverage area in an environment with very weak Wi-Fi signal. After reconstructing the data in a shielded room in the laboratory, the device's various indicators can be tested under extreme network conditions.

[0066] Congested network environment: This involves adding several network-using devices to a Wi-Fi network, collecting the signaling of the working channels between the Wi-Fi network and each network-using device, and then restoring the data in a shielded room in the laboratory to test the device's various indicators under a congested network environment.

[0067] Severe packet loss environment: This involves moving the device between obstacles while transmitting data, resulting in significant packet loss. In this scenario, signaling data is collected from the working channel between the Wi-Fi network and the obstacles, and then recreated in a shielded laboratory environment. This allows testing the device's performance in such an environment. By using typical scenario data collected from real-world Wi-Fi environments and recreating it in a shielded laboratory setting, the goal of highly replicating real-world scenarios is achieved, migrating uncontrollable live network testing to a controlled laboratory environment.

[0068] In a specific embodiment, step S2, which involves acquiring signaling of a designated working channel through a data acquisition unit, specifically includes...

[0069] Using packet capture tools, the AP devices in the real Wi-Fi scenario environment to be collected are scanned for a specified working channel to obtain IEEE 802.11 protocol layer signaling;

[0070] The packet capture tool can collect data from all specified working channels within the scope of the IEEE 802.11 protocol, and supports only one working channel at a time.

[0071] The packet capture tools include, but are not limited to, Wireshark, Fiddler, and Sniffer.

[0072] In a specific embodiment, the simulation restoration processing unit in step S3 filters the acquired signaling, specifically by:

[0073] Step S3.1: Read the signaling dataset acquired by the data acquisition unit;

[0074] The signaling dataset is type data collected within the scope specified by the IEEE 802.11 protocol; the type data includes, but is not limited to, Wi-Fi network parameters, signal strength, packet size, data latency, and data packets;

[0075] Step S3.2: Filter out the signaling frames of the IEEE 802.11 protocol MAC layer and extract the signaling data frames, control frames and management frames;

[0076] Furthermore, the data frame includes the data packet rate, signal strength, and transmission power;

[0077] The filtered signaling frames include Beacon frames, Probe Request frames, Probe Response frames, Authentication frames, and Disassociation frames.

[0078] Step S3.3: Obtain the signaling data to be simulated based on the data frame, control frame, and management frame of the signaling;

[0079] The signaling data to be simulated includes the AP device identification keyword in the signaling, as well as the signaling length, timestamp, and signal strength;

[0080] Step S3.4: Send the signaling data to be simulated to the data transmission unit. The simulation restoration processing unit is a tool or software capable of analyzing the signaling data acquired by the data acquisition unit to extract attributes including, but not limited to, transmission timestamps, data packet size, data delay time, and signal strength.

[0081] In a specific embodiment, step S4 involves grouping and organizing the filtered signaling according to different signal strengths. The grouping method is to sort the signal strength values ​​in descending order and divide them into four threshold ranges according to the set strength signal. Signaling with different signal strengths is then divided into four different signal strength groups: strong, medium, weak, and extremely weak, according to the four threshold ranges.

[0082] Due to the different locations and antenna radio frequency capabilities of various AP devices (Wi-Fi or routers) in the current network environment, the signaling is classified and organized according to the data packet rate and signal strength values ​​obtained in the signaling data frame. The data packet rate, signal strength, transmission power and other information can be viewed in the Radiotap Header field of the signaling.

[0083] The formula for calculating the signal strength is as follows:

[0084] Signal Strength(dBm)=10log10(Pout / Pin)+Gtx+Grx-PL

[0085] In the formula: Signal Strength represents signal strength; Pout represents signal transmit power; Pin represents signal receive power; Gtx represents the gain of the transmit antenna; Grx represents the gain of the receive antenna; PL represents the path loss of signal transmission.

[0086] A laboratory-based Wi-Fi scene recreation system, such as Figure 2 As shown, it includes several AP devices, a data acquisition unit, a simulation and restoration processing unit, and a shielded room; and the shielded room is equipped with a data transmission unit, a signaling strength management unit, and several antenna units;

[0087] The AP device is used to establish a Wi-Fi network environment at a preset location;

[0088] The data acquisition unit is used to scan the surrounding Wi-Fi network environment, collect the signaling of the designated working channel of the AP device, and transmit it to the simulation restoration processing unit;

[0089] The simulation restoration processing unit communicates with the data acquisition unit and the data transmission unit, respectively.

[0090] Furthermore, the simulation restoration processing unit is used to filter the signaling acquired by the data acquisition unit and transmit the filtered signaling to the data transmission unit.

[0091] The data transmission unit is used to organize signaling groups of different signal strengths into different signal strength classification pools, and send the organized signaling groups to the signal strength management unit through the signaling transmission device.

[0092] When the data sending unit groups signaling packets of different signal strengths into different signal strength classification pools, each signal strength pool, after receiving the transmitted signaling, will send feedback to the data sending unit indicating that it has received the signal. Upon receiving the feedback signal, the data sending unit will match a signaling sending device for that signal strength pool to send the signaling to the signal strength management unit. The signaling sending device can be any electronic device capable of transmitting Wi-Fi communication data, used to send the collected and processed signaling set in a sequence set manner. Figure 3 As shown, signaling transmission devices, which are typically half the number of attenuator tubes, are placed in the shielded room. Based on the number of signal strength pools in the classified signaling and the number of signal strength pools classified during the current scene restoration, the same number of signaling transmission devices are automatically requested to participate in the current scene restoration process. Each signaling transmission device needs to be connected to the two channels of the attenuator using a feeder.

[0093] The signaling strength management unit is used to provide several communication channels for signaling signal strength adjustment, and the signaling strength management unit is connected to the antenna unit through the communication channels;

[0094] The antenna unit is used to transmit the signaling from the channel of the signal strength management unit to the shielded room in a timely manner, ultimately achieving the purpose of recreating a complex environment within the shielded room. The antenna unit can be any component capable of transmitting or receiving electromagnetic waves, used to transmit the signaling after signal strength adjustment into the shielded room to achieve the effect of recreating a complex scene. The number of antenna units should be consistent with the number of channels of the attenuator, and each channel needs to be connected to an antenna via a feed line.

[0095] A shielded room, also known in the industry as an anechoic chamber or shielded room, is used to isolate a Wi-Fi environment from external signals, preventing the restored Wi-Fi environment from being affected by random, unknown signals. Because the space inside the shielded room is large enough to house attenuators and all transmitting equipment, it is essential to ensure proper shielding.

[0096] In a specific embodiment, the data sending unit includes one or more electronic devices capable of sending Wi-Fi communication signaling data;

[0097] The electronic device includes a communication antenna, a processor, and a memory; and the memory stores a programming program for execution by the processor.

[0098] In a specific embodiment, the signal strength management unit includes an attenuator with several communication channels or a device capable of adjusting the Wi-Fi signal strength;

[0099] Furthermore, each pair of adjacent communication channels is matched with a signal strength classification pool, and the signal strength adjustment within the communication channel matched with any signal strength classification pool is the same. Signaling data of different signal strengths and rates are grouped and organized. In the laboratory, a signal strength management unit was added to achieve realistic scenario reproduction. However, the attenuator device used as the signal strength management unit has a control attenuation interface response time on the order of seconds, which is far from meeting the requirements of the signaling sequence in the playback channel. Therefore, the signal strength management unit is designed to operate with an attenuator with 32 channels. Each pair of channels is matched with one of the signal strength classification pools in the current network environment. All signaling within this signal strength range is transmitted through a data transmission unit via the attenuator channel matched with that signal strength classification pool. This method supports the transmission of up to 16 groups of signaling from different signal strength ranges.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
