Description

[0002] In related technologies, when testing the wireless interference of network communication devices, it is usually necessary to measure the receiving sensitivity under wired communication and the receiving sensitivity under wireless communication, and the difference between the two is the degree of interference suffered by the device under wireless communication. In traditional interference test methods, if an accurate test of the degree of interference is required, it is necessary to accurately measure the attenuation under wired communication and the attenuation under wireless communication. However, there are errors in the line loss measured by the measuring device, and when electromagnetic waves are transmitted in a medium, the attenuation degree of electromagnetic waves at different frequency points in the same medium is different. During the test process, the attenuation values at only a few discrete points are usually used to simulate the attenuation within the entire frequency band, and the method of using the attenuation at discrete points to replace the attenuation within the entire frequency band further introduces fitting errors. Therefore, traditional interference test methods always introduce the sum of measurement errors and fitting errors; in the interference test methods in the prior art, the accuracy and precision of the degree of interference suffered by the device under wireless communication determined are relatively low, and moreover, the test process of traditional interference test methods is relatively complex and the test efficiency is relatively low.

[0028] The following will describe in detail the embodiments of the present application. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, but should not be construed as a limitation to the present application.

[0029] The terms "first" and "second" in the description, claims and drawings of the embodiments of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0030] First, some terms in the embodiments of the present application will be explained below to facilitate the understanding of those skilled in the art.

[0031] MCS: Modulation and Coding Scheme, modulation and coding strategy; the configuration of the 802.11n radio frequency rate is achieved through the MCS index value. The MCS modulation and coding table is a representation form proposed by 802.11n to characterize the communication rate of the WLAN. MCS takes the factors affecting the communication rate as the columns of the table and the MCS index as the rows to form a rate table. Therefore, each MCS index actually corresponds to the physical transmission rate under a set of parameters.

[0032] Aiming at the defects of low test efficiency and poor accuracy in the interference test method in the related technology, this application proposes an optimization method, which eliminates the error caused by test line loss in the traditional test method, and proposes a method that can accurately measure the magnitude of wireless interference without testing the line loss under wired communication and wireless communication.

[0033] The inventor found through research that for the same network communication device, for the same modulation method and even different modulation methods, when the device under test transmits data to the comprehensive tester side, if the communication setting information on the device under test side remains unchanged, and when testing the receiving sensitivity of the device under test, the test data transmission rate, test bandwidth, and test frequency band information in the test setting information remain unchanged. For the power (TX) obtained by the comprehensive tester when the device under test transmits data to the comprehensive tester side, and the transmission power (RX) of the comprehensive tester side corresponding to the receiving sensitivity of the device under test, that is, the sum of the relative sensitivities is a fixed value, that is, TX + RX = fixed value.

[0034] Specifically, the foregoing communication setting information may include: communication data transmission power, communication data transmission rate, communication bandwidth, and communication frequency band information. Among them, the communication data transmission rate may include the wireless mode type (such as 11n mode) and MCS index information (such as MCS0).

[0035] The test setting information includes: test data transmission power, test data transmission rate, test bandwidth, and test frequency band information.

[0036] Specifically, let: the actual transmission power of the network communication device be P D , the power received by the comprehensive tester be P W (i.e., the measured TX), the actual loss of the link be L 实 , the line loss table compensates for the line loss L 补 , the actual transmission power of the comprehensive tester be S W (i.e., the measured RX), the minimum power received by the network communication device (i.e., the receiving sensitivity) be S D , under wired communication conditions, the power P received by the comprehensive tester w1 , the actual transmission power P of the network communication device D , the actual loss of the link be L 实, the line loss meter compensates for the line loss L 补 The relationship with satisfies the following formula (1), and the minimum power (i.e., the receiving sensitivity) S received by the network communication device D , the power S actually emitted by the comprehensive tester w1 (i.e., the measured RX) satisfies the following formula (2);

[0037] P W1 =P D -L 实 +L 补1 (1)

[0038] S D =S W1 -L 实 +L 补1 (2)

[0039] Transposing (2) gives

[0040] S W1 =S D +L 实 -L 补1 (3)

[0041] (1)+(3) formula, the formula (4) can be determined as:

[0042] S W1 +P W1 =S D +P D (4)

[0043] Furthermore, under the condition that the network communication device and the comprehensive tester are wired-connected, that is, when wired communication is carried out, the antenna of the network communication device is not connected and it is considered not to be interfered. When the test data transmission rate, test bandwidth, and test frequency band information in the communication setting information and test setting information remain unchanged, the S W1 +P W1 measured by the comprehensive tester is equal to the S D +P D of the network communication device. For the same network communication device, when the communication setting information remains unchanged, the receiving sensitivity S D is fixed, and the transmit power P D is also fixed.

[0044] Furthermore, under the condition that the network communication device and the comprehensive tester are wirelessly connected, that is, when wireless communication is carried out,

[0045] The network communication device will introduce interference signals due to the operation of different internal hardware or software modules, or be affected by other external electromagnetic waves, thus deteriorating the receiving sensitivity of the network communication device. At this time, the power S actually emitted by the comprehensive tester w2 is greater than or equal to Sw1 value. Furthermore, S is determined W2 +P W2 ≥S D +P D , therefore, it is only necessary to compare the two test values S W1 +P W1 and S W2 +P W2 under wired communication and wireless communication, and the difference between them can be used to determine the degree of interference on the network communication device under wireless communication conditions. Among them, P w2 is the power received on the synthesizer when the network communication device communicates with the synthesizer wirelessly for P D the synthesizer.

[0046] Optionally, the wireless modulation method involved in this application may be the DSSS-CCK (Direct Sequence Spread Spectrum-Complement Code Keying) mode, or the OFDM (Orthogonal Frequency Division Multiplexing) mode. In this regard, this application does not make any limitations.

If so, it determines the first transmission power information according to the first test setting information corresponding to the first test instruction. If not, it reduces the first test data transmission power according to a preset adjustment rule and sends the first test instruction to the comprehensive tester again (the first test data transmission power included in the first test setting information corresponding to this first test instruction is the reduced test data transmission power), so that the comprehensive tester sends the first test data packet to the device under test again based on the first test setting information corresponding to the first test instruction, that is, loops through S1 - S3 until the control device determines that the ratio of the number of packets of the first received packet to the number of packets of the first test data packet is less than the first preset threshold, and then determines the first transmission power information according to the first test setting information corresponding to the current first test instruction.

[0083] Further, when the ratio of the number of packets of the second received packet to the number of packets of the second test data packet is less than the second preset threshold, the corresponding second packet loss rate is greater than the second preset packet loss rate, and the second preset threshold corresponds to the second preset packet loss rate.

[0084] Optionally, the foregoing first preset threshold is the same as the second preset threshold, and the first preset packet loss rate is the same as the second preset packet loss rate.

[0085] Further, when performing the first reception sensitivity test on the device under test under the condition that the device under test is wired to the comprehensive tester, the first test data transmission power included in the first test setting information corresponding to the initial first test instruction may be the same as or different from the second test data transmission power included in the second test setting information corresponding to the initial second test instruction when performing the second reception sensitivity test on the device under test under the condition that the device under test is wirelessly connected to the comprehensive tester.

When the comprehensive tester determines the first received power information according to the line loss information, it specifically includes: the comprehensive tester determines the first received power information based on the sum of the first initial power information received from the device under test and the line loss information. Accordingly, when the comprehensive tester determines the second received power information according to the line loss information, it specifically includes: the comprehensive tester determines the second received power information based on the sum of the second initial power information received from the device under test and the line loss information.

[0098] Wherein, the first initial power information is the communication data transmission power corresponding to the first communication data, and the second initial power information is the communication data transmission power corresponding to the second communication data.
