Description

Technical Field

[0001] The present application belongs to the field of communication technology, and in particular, relates to a radiation sensitivity test system, test method and computer equipment for WiFi7 equipment. Background Art

[0002] Wi-Fi7 is a protocol standard that has become popular in recent years. Most of the latest mainstream routers already support Wi-Fi7 technology. Wi-Fi 7 is an upgraded version of Wi-Fi6. It mainly introduces the 6GHz band and 4096 high-order modulation based on Wi-Fi6, which can avoid the interference caused by many devices using the 5GHz band and greatly improve the communication rate. Compared with Wi-Fi6, Wi-Fi 7 brings a new 6GHz band, accommodating 14, 80MHz channels and 7, 160MHz channels, and 3 320M bands. It can also support 4096QAM high-order modulation, and the MCS13 rate sensitivity of 320M is increased to -34dbm. In this case, the traditional method of testing radiation sensitivity faces a big problem, that is, when the position of the wifi7 device to be tested is often not adjusted properly, the total attenuation of the link from the wireless integrated test instrument to the receiving antenna of the wifi7 device to be tested is often prone to attenuation of more than tens of db, and the maximum transmission power of the wireless integrated test instrument is generally 0dbm. At this time, the power reaching the receiving antenna of the wifi7 device to be tested may be less than the receiver sensitivity. Then at this time, the receiver cannot receive the packet and cannot measure the true radiation sensitivity value. Even if the direction of a certain channel is adjusted, due to the large span of the 6G frequency band, the air attenuation at the same position also varies greatly. In addition, due to design reasons, the product 2.4G / 5G / 6G may have up to ten antennas placed. Once an antenna is adjusted in direction, the sensitivity of other antennas often cannot be measured due to attenuation problems, and the placement of the wifi7 device to be tested needs to be adjusted continuously. In order to improve efficiency, the present invention uses multi-channel antennas to test the receiver at multiple different angles, which can greatly reduce the manual adjustment of the position of the wifi7 device to be tested, and maximize the efficiency of the automated test level.

[0045] Embodiment 1

[0046] refer to Figure 1 , Figure 1 A schematic diagram of an embodiment of a test system provided by the present application is shown. As an example but not a limitation, the test system of the present embodiment is deployed in a shielding room to test the radiation sensitivity of a WiFi7 device to be tested in a shielding box in the shielding room. The WiFi7 device to be tested in the present embodiment may be a WiFi7 router. The test system includes a test device 1, a wireless integrated tester 2, and a radio frequency matrix switch 3.

[0047] The test device 1 is connected to the wireless integrated tester 2, the radio frequency matrix switch 3 and the WiFi 7 device 4 to be tested through network cables respectively;

[0048] The wireless integrated tester 2 is connected to the main circuit of the RF matrix switch 3 through a RF cable, and the n branches of the RF matrix switch 3 are connected to the n receiving antennas inside the shielding box 5 through RF cables; based on the above Figure 1On the basis of the test system shown, the embodiment of the present application proposes a method for testing the radiation sensitivity of a WiFi7 device, which mainly includes steps S11 to S31; since the WiFi7 device to be tested often has multiple frequency bands and multiple groups of antennas, such as the coexistence of 2G, 5G, and 6G frequency bands, and 5G and 6G antennas can generally reach as many as 4, the steps S11 to S31 of the method for testing the radiation sensitivity of the WiFi7 device of the embodiment of the present application can detect the radiation sensitivity of any channel ("any channel" or "mth channel") of any frequency band of the WiFi7 device to be tested; it can be understood that the WiFi7 device to be tested in this embodiment has multiple frequency bands, including 2G, 5G, and 6G frequency bands. Frequency refers to the frequency range of wireless signals. Multiple channels can be divided in each frequency band (for example, the WiFi7 device in this embodiment has a total of the 1st channel, the 2nd channel, the 3rd channel... the mth channel), and these channels are isolated from each other in frequency to avoid mutual interference. By supporting multiple frequency bands (2G, 5G, and 6G frequency bands), WIFI7 devices can divide more channels on different frequency bands, thereby providing more communication channels and improving network throughput and capacity. The corresponding relationship between the corresponding frequency band and an antenna to be tested of the WIFI7 device can be one-to-one (one frequency band corresponds to one antenna to be tested, for example, the 2G frequency band corresponds to antenna 1 to be tested of the WiFi7 device to be tested, the 5G frequency band corresponds to antenna 2 to be tested of the WiFi7 device to be tested, and the 6G frequency band corresponds to antenna 3 to be tested of the WiFi7 device to be tested), or one-to-many (one frequency band corresponds to multiple antennas to be tested, for example, the 2G frequency band corresponds to antenna 1 to be tested of the WiFi7 device to be tested, the 2G frequency band corresponds to antenna 2 to be tested of the WiFi7 device to be tested, and the 2G frequency band corresponds to antenna 3 to be tested of the WiFi7 device to be tested).

[0049] This embodiment first takes the radiation sensitivity of the initial channel 1 of the 2G frequency band of the WiFi7 device to be tested as an example, referring to Figure 2 , the test method comprises:

[0050] In the first stage, step S11: the test device sends a first instruction to the WiFi7 device 4 to be tested, so that the signal transmission module of the WiFi7 device 4 to be tested continuously transmits a fixed power signal through the mth channel, so that the fixed power signal is transmitted to the n receiving antennas inside the shielding box respectively, wherein m and n are both integers;

[0051] Step S12: the test device controls the matrix switch to test the power received by the n receiving antennas respectively to obtain n power receiving results, and selects the receiving antenna with the maximum received power from the n receiving function results as the target receiving antenna;

[0052] In the specific implementation, refer to Figure 1In this embodiment, four receiving antennas (ie, n=4) are arranged inside the shielding box 5. Figure 1 Point A, point B, point C, and point D in the figure correspond to four different receiving antennas respectively; accordingly, the system configures four branches for the RF matrix switch 3, and each branch is connected to the corresponding receiving antenna inside the shielding box through an RF cable; at the same time, the wireless integrated tester 2 can only send and receive RF signals with one branch of the RF matrix switch.

[0053] The test device sends the first command to let the WiFi7 device to be tested continuously send a known fixed power signal (such as a fixed power of 20dbm), and then controls the RF matrix switch to check in four branches in turn, so that the receiving antenna A, receiving antenna B, receiving antenna C, and receiving antenna D can be connected to the wireless integrated tester in turn. Under the same fixed power of 20dbm environmental conditions, the receiving antenna A, receiving antenna B, receiving antenna C, and receiving antenna D are measured in turn. The test device selects the receiving antenna with the largest receiving power as the target receiving antenna for radiation sensitivity test. For example, if the power received by the four receiving antennas A, B, C, and D is -15dbm, -20dbm, -30dbm, and -35dbm respectively, then select receiving antenna A as the target receiving antenna, re-control the RF matrix switch to connect the target receiving antenna A, and use the total attenuation = 20-(-15) = 35db as the test attenuation of the wireless integrated tester.

[0054] In the second stage, step S21: the test device collects the actual received power signal received by the target receiving antenna at the kth moment;

[0055] Step S22: the testing device calculates the total attenuation of the receiving link of the receiving module of the WiFi7 device 4 to be tested based on the fixed power signal and the actual receiving power signal;

[0056] It can be understood that the kth moment represents the current moment. The test device in the second stage calculates the total attenuation between the transmission of the WiFi7 device to be tested to the wireless integrated test instrument. The calculation method is to subtract the power currently received by the wireless integrated tester from the known fixed power signal (the power currently received by the wireless integrated tester is the actual receiving power signal received by the target receiving antenna at the kth moment), which is the total attenuation of the transmission link of the signal transmission module of the WiFi7 device to be tested. Since the design of the WiFi7 device to be tested is that the transmitting module and the receiving module are implemented using the same antenna, it can be obtained through reciprocity that the total attenuation of the receiving link of the WiFi7 device to be tested is also equal to the above-mentioned calculated value;

[0057] In the third stage, step S31: the wireless integrated tester 2 tests the sensitivity of the mth channel of the WiFi7 device 4 to be tested according to the total link attenuation.

[0058] Specifically, after the wireless integrated tester obtains the total attenuation of the receiving link, it can perform an automated test of the radiation sensitivity of the initial channel 1 of the antenna under test corresponding to the 2G frequency band of the WiFi7 device under test. The test includes traversing the mode, rate, bandwidth, etc. as required, that is, the test system needs to systematically and comprehensively test the radiation sensitivity of the WiFi7 device under test under different communication modes, data transmission rates, channel bandwidths, etc. according to specific test requirements or standards, so as to ensure that the WiFi7 device under test can maintain stable performance under various conditions.

[0059] The beneficial effect of the first embodiment of the present invention is that due to the large attenuation of the 6G frequency band unique to WIFI7 devices, the traditional method of testing radiation sensitivity requires manual and continuous adjustment of the position of the WIFI7 device to be tested to meet the requirement that the receiving link attenuation is less than the sensitivity. Otherwise, the link attenuation is too large. Since the transmission power of the wireless integrated test instrument is limited, the maximum power transmitted by the instrument will be lower than the sensitivity value after the link attenuation. At this time, the sensitivity value cannot be measured. The first embodiment of the present application automatically selects the link with the smallest attenuation to test the receiving sensitivity by placing four receiving antennas in different directions, thereby achieving work that could not be automated, changing the inefficient practice of manually and continuously adjusting the position of the WIFI7 device to be tested, and maximizing efficiency improvement.

[0060] Embodiment 2

[0061] Embodiment 2 of the present application is based on the above-mentioned embodiment 1, that is, an extension of the testing method of embodiment 1, and the testing method further includes:

[0062] The fourth stage, step S41, in the third stage, if the wireless integrated tester cannot measure the radiation sensitivity of a channel of the Lth antenna to be tested in the specified frequency band, then re-execute the steps of the first stage to the third stage to select a new target receiving antenna until the radiation sensitivity test is successful.

[0063] It is understandable that, since the WiFi7 device has multiple frequency bands, and each frequency band may correspond to multiple different antennas to be tested of the WiFi7 device itself, and each antenna to be tested corresponds to multiple channels, the test method of the embodiment of the present application needs to repeatedly execute the methods of the first stage to the third stage in the first embodiment multiple times to measure the radiation sensitivity of a channel of a certain antenna to be tested in a certain specified frequency band of the WiFi7 device as needed, that is, the first instruction in the first embodiment is used to determine the radiation sensitivity of the mth channel of the Lth antenna to be tested of the WiFi7 device to be tested in the specified frequency band;

[0064] Then, after completing the radiation sensitivity test of the initial channel 1 of the first antenna to be tested in the 2G frequency band of the WiFi7 device to be tested as exemplified in Example 1, the radiation sensitivity of each channel of each antenna to be tested in the 2G frequency band of the WiFi7 device to be tested will also be measured; if a channel is subsequently attenuated too much and the wireless integrated tester fails to perform radiation sensitivity measurement, the aforementioned steps from the first stage to the third stage are repeated to select a new target receiving antenna until the radiation sensitivity test is successful.

[0065] Furthermore, in conventional technology, since WIFI7 devices often have multiple frequency bands and multiple groups of antennas, such as the coexistence of 2G, 5G, and 6G frequency bands, 5G and 6G antennas can generally reach as many as 4 (for example, one frequency band can correspond). If the design is a built-in antenna, it is often impossible to ensure that the polarization directions of the antennas are the same. The attenuation difference from each antenna to be tested of the WIFI7 device to the same receiving antenna is very large. Therefore, when testing the receiving sensitivity of different antennas to be tested of the WIFI7 device, it is often necessary to adjust the position of the WIFI7 device to reduce the attenuation before the receiving antenna, which is extremely inefficient. Therefore, after the fourth stage of the above-mentioned test method, the test method of the embodiment of the present application also includes:

[0066] The fifth stage, step S51, after completing the test of the radiation sensitivity of each channel of the Lth antenna to be tested in the specified frequency band of the WiFi7 device to be tested, the radiation sensitivity of each channel of other antennas to be tested in the specified frequency band of the WiFi7 device to be tested is tested according to the steps of the first stage to the third stage.

[0067] It is understandable that after completing the radiation sensitivity test of each channel of the first antenna to be tested in the 2G frequency band (specified frequency band) of the WiFi7 device to be tested in the above-mentioned fourth stage, the radiation sensitivity test of each channel of other antennas to be tested in the 2G frequency band (specified frequency band) will be carried out according to the steps of the first stage to the third stage.

[0068] Step S52, after completing the test of the radiation sensitivity of all antennas to be tested in the specified frequency band of the WiFi7 device to be tested, the radiation sensitivity of other frequency bands of the WiFi7 device to be tested is tested according to the steps of the first stage to the third stage.

[0069] It is understandable that after completing the radiation sensitivity test of each channel of each antenna under test in the 2G frequency band (specified frequency band) of the WiFi7 device under test in the above step S51, the radiation sensitivity of each channel of other frequency bands (5G frequency band, 6G frequency band) of the WiFi7 device under test will be tested according to the steps of the first stage to the third stage.

[0070] In this way, all frequency bands and antennas of the WiFi7 device to be tested are traversed. Save the data and output the test report, and give a pass or fail conclusion according to the test specification. Save the receiving antenna number used in each test for the WiFi7 device to be tested. It can be used as a reference for the second test or multiple repeated tests, reducing the process of selecting antennas and further improving test efficiency.
