Fig. 2 shows a schematic implementation flow diagram of a method for testing wireless connection performance according to an embodiment of the present disclosure.
Referring to fig. 2, a method for testing wireless connection performance in an embodiment of the present disclosure at least includes: operation 201, receiving a channel simulation attenuation value of a test channel for performing a wireless connection test on a device to be tested; operation 202, determining an uplink channel back-off power and a downlink channel back-off power for channel transmission between the device to be tested and the wireless access device according to the channel simulation attenuation value of the test channel; operation 203, detecting a signal of successful wireless connection sent by the device to be tested; operation 204, sending a wireless connection performance test instruction to the device to be tested and the wireless access device, where the connection performance test instruction carries an uplink channel backoff power and a downlink channel backoff power for channel transmission between the device to be tested and the wireless access device; operation 205, receiving channel transmission data information of a test channel sent by the wireless access device in response to the wireless connection performance test instruction; and operation 206, determining a wireless connection performance test result of the device under test according to the channel transmission data information.
In operation 201, a channel simulation attenuation value of a test channel for performing a wireless connection test on a device under test is received.
Specifically, the channel simulation attenuation value of the current test may be received first, and the channel simulation attenuation value may be configured in advance through software, or may be set according to a specific actual requirement before the test starts.
For example, taking the device to be tested as a notebook computer as an example, the channel analog attenuation value is a spatial attenuation value corresponding to the notebook computer and the wireless access device at different distances. Therefore, the channel simulation attenuation value can be set according to the actual requirement of a conventional user on the distance between the notebook computer and the wireless access equipment.
Specifically, the channel simulation attenuation value may be determined according to a distance between the notebook computer and the wireless access device through a wireless space electromagnetic wave attenuation formula, which is as follows:
Figure BDA0003769166050000061
wherein PathLoss represents a channel analog attenuation value, f represents a frequency of a wireless frequency band, d represents a distance between the wireless access device and the device to be tested, and c represents a light speed.
Through the wireless space electromagnetic wave attenuation formula, the corresponding channel simulation attenuation value can be calculated according to the distance between the notebook computer and the wireless access equipment. Therefore, when the wireless connection performance of the equipment to be tested at different distances from the wireless access equipment needs to be tested, the channel simulation attenuation value can be set directly according to the distance.
For example, taking the frequency of the wireless frequency band of the test as 2.4Ghz as an example, the distance for performing the wireless connection performance test on the device to be tested may be 2 meters, 5 meters, 10 meters, 20 meters, 30 meters, 50 meters, 100 meters, 200 meters, and 618 meters, and the channel simulated attenuation values corresponding to the distances obtained according to the wireless space electromagnetic wave attenuation formula are 46.0dB, 54.0dB, 60.0dB, 66.0dB, 69.5dB, 74.0dB, 80.0dB, 86.0dB, and 95.8dB. At the beginning of the test, the obtained channel simulation attenuation values are configured, so that the wireless connection performance of the equipment to be tested under different channel simulation attenuation values can be further tested.
It should be noted that, the above descriptions of the channel simulation attenuation value determination process are all for better describing the embodiments of the present disclosure, and the specific process of determining the channel simulation attenuation value in the practical application process may be determined by using other applicable manners and ways, which are not limited in this disclosure.
In operation 202, according to the channel simulation attenuation value of the test channel, an uplink channel back-off power and a downlink channel back-off power for channel transmission between the device under test and the wireless access device are determined.
Specifically, the process of channel transmission between the device to be tested and the wireless access device is divided into uplink channel transmission and downlink channel transmission. The uplink channel transmission represents that the equipment to be tested sends the transmitting power to the wireless access equipment, and the downlink channel transmission represents that the wireless access equipment sends the transmitting power to the equipment to be tested.
The distance exists between the device to be tested and the wireless access device, after the device to be tested and the wireless access device send the transmitting power, the transmitting power can be attenuated due to the distance, and the simulated channel attenuation value is used for representing the corresponding space attenuation value between the device to be tested and the wireless access device under different distances. Therefore, under the condition of receiving the channel simulation attenuation value, the transmitting power which is transmitted by the equipment to be tested and is to be transmitted after being attenuated and the transmitting power which is transmitted by the wireless access equipment and is to be transmitted after being attenuated can be directly determined according to the channel simulation attenuation value. Therefore, the scheme that the adjustable attenuator is used for respectively attenuating the transmitting power of the equipment to be tested and the transmitting power of the wireless access equipment according to the channel simulation attenuation value in the existing scheme is effectively avoided, and the influence on the test caused by the conditions that the adjustable attenuator breaks down and the like in the test process is effectively avoided.
Hereinafter, the uplink channel back-off power represents the transmission power that should be sent after the transmission power sent by the device under test is attenuated, and the downlink channel back-off power represents the transmission power that should be sent after the transmission power sent by the wireless access device is attenuated.
In operation 203, a signal of successful wireless connection sent by the device under test is detected.
Specifically, since the wireless connection performance test of the device to be tested needs to be performed on the basis that the device to be tested and the wireless access device are in wireless connection, the wireless connection condition of the device to be tested and the wireless access device needs to be detected all the time in the test process.
Further, the wireless access device sends a signal of successful wireless connection under the condition that the wireless connection with the device to be tested is successful, and the wireless connection between the wireless access device and the device to be tested is proved to be successful under the condition that the signal of successful wireless connection is detected.
In operation 204, a wireless connection performance test instruction is sent to the device to be tested and the wireless access device, where the connection performance test instruction carries an uplink channel backoff power and a downlink channel backoff power for channel transmission between the device to be tested and the wireless access device.
Specifically, a connection performance test instruction can be sent to the wireless access device and the device to be tested when it is determined that the wireless access device and the device to be tested are successfully wirelessly connected, where the connection performance test instruction carries the determined uplink channel back-off power and downlink channel back-off power. In this way, the uplink power in the channel transmission process between the device to be tested and the wireless access device can be configured to be the uplink channel backoff power determined by the attenuation value of the current test through the connection performance test instruction, and the downlink power in the channel transmission can be configured to be the downlink channel backoff attenuation value determined by the channel simulation attenuation value of the current test.
In operation 205, channel transmission data information of a test channel transmitted by the wireless access device in response to the wireless connection performance test instruction is received.
Specifically, after sending the throughput rate test instruction to the device to be tested and the wireless access device, the channel transmission data information generated in the process of channel transmission of the device to be tested and the wireless access device, which is sent by the wireless access device, can be received in real time.
At operation 206, a wireless throughput rate test result of the device under test is determined according to the channel transmission data information.
Specifically, the channel transmission information includes a throughput rate, and the wireless connection performance may be determined according to the throughput rate, so that a wireless throughput rate test result of the device under test can be obtained according to the throughput rate shown by the channel transmission information.
Fig. 3 illustrates a flowchart of an implementation of determining a back-off power according to an embodiment of the present disclosure.
In an embodiment of the present disclosure, in the above operation 201, determining an uplink channel back-off power and a downlink channel back-off power for channel transmission according to the channel attenuation value of the current test includes:
in operation 301, a power backoff value is determined according to the attenuation value of the channel under test and a preset standard attenuation value.
Specifically, in the process of testing the wireless connection performance of the device to be tested, the transmission power of the wireless access device needs to be sent to the device to be tested through the test antenna, a fixed distance exists between the test antenna and the device to be tested, and a channel simulation attenuation value corresponding to the fixed distance is a preset standard attenuation value. Further, the power back-off value is a difference value between a preset standard attenuation value and the channel attenuation value of the current test.
For example, a fixed distance between the test antenna and the device under test is 2 meters, and a frequency of a wireless channel is 2.4GHz, that is, a predetermined standard attenuation value is 46 dB. The channel simulation attenuation values of the test can be 48dB, 76dB, 86dB, 96dB and the like, and then the corresponding power back-off values of the test can be obtained to be-2, -30, -40 and-50.
It should be noted that, the preset standard attenuation value is not specifically limited in the present disclosure, and the preset standard attenuation value needs to be specifically set according to the distance between the test antenna and the device to be tested and the test frequency in the actual test process.
Operation 302, determining an uplink channel back-off power of the device under test according to the maximum transmission power of the device under test and the power back-off value.
Specifically, when the device to be tested performs wireless performance, after the device to be tested is wirelessly connected to the wireless access device, the device to be tested can send the maximum unattenuated transmission power supported by the device to be tested to the wireless access device.
Further, the maximum transmission power supported by the device to be tested is added to the power back-off value to obtain the transmission power that the device to be tested should send in the test process, that is, the uplink channel back-off power.
Operation 303, determining a downlink channel back-off power of the wireless access device according to the maximum transmission power of the device to be wirelessly accessed and the power back-off value.
Specifically, the determining process of the downlink channel back-off power may adopt a determining process the same as or similar to the uplink channel back-off power, that is, the calculation is performed through the maximum transmission power supported by the wireless access device, which is not described herein again.
In a specific application example of this embodiment of the present disclosure, the uplink channel back-off power and the downlink channel back-off power for channel transmission may be determined according to the channel attenuation value of this test and a preset power table.
Specifically, a plurality of channel analog attenuation values that need to be tested for the device under test may be determined first. Further, a plurality of back-off values corresponding to the plurality of channel simulation attenuation values are calculated through the channel simulation attenuation values, and a plurality of uplink channel back-off powers of the corresponding device to be tested and a plurality of downlink channel back-off powers of the wireless access device are respectively calculated according to the back-off values. And finally, establishing a table of the channel simulation attenuation value, the calculated backoff value, the uplink channel backoff power of the equipment to be tested and the downlink channel backoff power of the wireless access equipment to obtain a preset power table for showing the corresponding relation between the channel simulation attenuation value and the uplink channel backoff power of the equipment to be tested and the downlink channel backoff power of the wireless access equipment.
Furthermore, a preset power table is configured in advance, and then after the channel analog attenuation value is received, the uplink channel back-off power and the downlink channel back-off power transmitted by the channel can be directly determined according to the preset power table.
For example, assume that the device to be tested is a notebook computer, the wireless access device is a wireless router, the fixed distance from the test antenna of the wireless access device to the device to be tested is 2 meters, and the frequency of the wireless frequency band of the test is 2.4GHz. Under the condition that the frequency of a wireless frequency band is 2.4GHz and the fixed distance between a test antenna and the device to be tested is 2 meters, the preset standard attenuation value is 46dB, the corresponding power back-off values of the test are respectively-2, -30, -40 and-50 under the assumption that the channel simulation attenuation values of the test are respectively 48dB, 76dB, 86dB, 96dB and the like. The maximum transmitting power of the notebook computer under 2.4GHz is generally 17dB, the maximum transmitting power of the wireless router under 2.4GHz is generally 20dB, therefore, the backspacing values are further used for obtaining the upstream channel backspacing powers of the corresponding notebook computer respectively as 18dB, -10dB, -20dB, -30dB, and the downstream channel backspacing powers of the corresponding wireless router respectively as 15dB, -13dB, -23dB and-33 dB.
Further, the calculated channel analog attenuation value, backoff value, uplink channel backoff power of the device under test, and downlink channel backoff power of the radio access device may be represented by a preset power table as shown in the following table.
Watch 1
Channel analog attenuation value Back off value Downlink channel back-off power Uplink channel back-off power
48dB -2 20–2＝18dBm 17-2＝15dBm
76dB -30 20–30＝-10dBm 17-30＝-13dBm
86dB -40 20–40＝-20dBm 17-40＝-23dBm
96dB -50 20–50＝-30dBm 17–50＝-33dBm
In one embodiment of the present disclosure, the channel transmission data information includes downlink channel transmission data information and uplink channel transmission data information; the downlink channel transmission data information is generated in the process that the wireless access equipment responds to the wireless throughput rate test instruction to send downlink channel back-off power to the equipment to be tested, and the uplink channel transmission data information is generated in the process that the equipment to be tested responds to the wireless throughput rate test instruction to send uplink channel back-off power to the wireless access equipment.
Specifically, in the process of channel transmission between the device to be tested and the wireless access device, the channel transmission process includes uplink channel transmission and downlink channel transmission, where the uplink channel transmission indicates that the device to be tested sends uplink channel back-off power to the wireless access device, and the downlink channel transmission indicates that the wireless access device sends downlink channel back-off power to the device to be tested.
Further, channel transmission data information for channel transmission can be generated in the process of channel transmission between the device to be tested and the wireless access device, and the channel transmission data information includes uplink channel transmission data information generated in the process of uplink channel transmission and downlink channel transmission data information generated in the process of downlink channel transmission.
In an embodiment of the present disclosure, when receiving a wireless throughput test instruction, a wireless access device may determine, according to a downlink channel backoff power carried in the wireless throughput test instruction, a downlink control word in its configuration for triggering sending of the downlink channel backoff power, so as to send the downlink channel backoff power to a device under test through triggering of the downlink control word.
In an embodiment of the present disclosure, when receiving a wireless throughput test instruction, a device under test can determine, according to uplink channel backoff power carried in the wireless throughput test instruction, an uplink control word in its configuration for triggering sending of the uplink channel backoff power, so as to send the uplink channel backoff power to a wireless access device through triggering of the uplink control word.
Specifically, before the equipment to be tested leaves a factory, a control word corresponding to each power transmitted by the equipment to be tested can be obtained through radio frequency calibration, so that a power control word table of the equipment to be tested can be generated, the power control word table is configured in the equipment to be tested before leaving the factory, when the equipment to be tested needs to transmit a certain power, the control word corresponding to the power can be determined and transmitted according to the power control word table, and then the equipment to be tested is triggered by the control word to transmit the corresponding power. It should be noted that, the process of obtaining the control word from the power is performed before factory shipment, and all schemes for determining the control word corresponding to the power from the power, which are commonly used in the art, can implement the scheme for obtaining the control word in the present disclosure, and therefore, no further description is given here.
Further, the process of the wireless access device is the same as that of the device to be tested, which is not described herein again.
In an embodiment of the present disclosure, the operation 206 specifically includes: and judging whether the wireless throughput rate shown by the channel transmission data information meets the throughput rate standard, judging that the wireless connection performance test result of the equipment to be tested is qualified under the condition that the wireless throughput rate meets the throughput rate standard, and judging that the wireless connection performance test result of the equipment to be tested is unqualified under the condition that the wireless throughput rate does not meet the throughput rate standard.
Specifically, different throughput rate standards are defined for different channel attenuation values, and in the process of channel transmission between the device to be tested and the wireless access device, the wireless access device records channel transmission data information generated in the channel transmission process and provides the channel data information to the control machine in real time.
Further, the channel transmission data information includes a wireless throughput rate, specifically including an uplink throughput rate in an uplink channel transmission process and a downlink throughput rate in a downlink channel transmission process. Corresponding throughput rate standards exist in the industry aiming at the uplink throughput rate and the downlink throughput rate under different channel simulation attenuation values.

and operation 01, sending a connection instruction to the device to be tested and the wireless access device, so that the wireless access device configures the wireless channel into the wireless channel shown by the wireless channel identifier of the current test according to the connection instruction and the wireless channel identifier of the current test carried by the wireless access device.
Specifically, the wireless connection performance testing process according to the embodiment of the present disclosure needs to be established on the basis that the device to be tested and the wireless access device are already in wireless connection, and therefore, here, the wireless connection between the device to be tested and the wireless access device needs to be established first.
Further, the wireless access device may include a plurality of wireless frequency channels, each wireless frequency channel being a channel, and the device under test may be capable of wirelessly connecting with the wireless access device on any wireless frequency channel. In the process of testing the wireless connection performance of the device to be tested, the embodiment of the disclosure can simulate the attenuation value for the channel after receiving the channel simulation attenuation value, and test the wireless connection performance of the device to be tested in a plurality of channels, that is, a plurality of wireless channels.
Therefore, when the device to be tested and the wireless access device are wirelessly connected, the wireless channel identifier of the current test can be added into the sent connection instruction, so that the wireless access device can configure the wireless channel as the wireless channel shown by the wireless channel identifier of the current test.
And operation 402, controlling the device to be tested to perform wireless connection with the wireless access device according to the identifier of the wireless channel tested this time when the wireless access device completes configuration of the wireless channel.
Specifically, after the wireless access device configures the wireless channel, when the device to be tested is wirelessly connected with the wireless access device, the device to be tested can be connected to the corresponding wireless channel, so that the wireless connection performance of the device to be tested under the wireless channel can be tested in the subsequent testing process.
In an embodiment of the present disclosure, the wireless throughput test result includes a wireless throughput test result of the device under test on a plurality of wireless channels corresponding to the plurality of wireless channels.
Specifically, in the process of testing the wireless connection performance of the device to be tested, the embodiment of the present disclosure needs to test the wireless connection performance of the device to be tested in a plurality of wireless channels included in the wireless access device. Therefore, the wireless throughput rate test result comprises a plurality of wireless throughput rate test results of the device to be tested under a plurality of wireless channels.
For example, the wireless channel that can be tested is described by taking the device to be tested as a notebook computer and the wireless access device as a wireless router again. The wireless router includes 13 wireless channels corresponding to 13 wireless channels, specifically, wireless channel 1, wireless channel 2, wireless channel 3, wireless channel 4, wireless channel 5, wireless channel 6, wireless channel 7, wireless channel 8, wireless channel 9, wireless channel 10, wireless channel 11, wireless channel 12, and wireless channel 13, when the frequency of the wireless frequency band is 2.4GHz. During the process of testing the wireless connection of the device to be tested, the wireless connection performance of the device to be tested under the wireless channels 1, 6 and 11 can be tested for the device to be tested.
Fig. 5 is a schematic diagram illustrating an implementation flow of a wireless connection performance test performed on a notebook computer according to an embodiment of the present disclosure.
Referring to fig. 5, in this specific application example of the embodiment of the present disclosure, the device to be tested is a notebook DUT, the wireless access device is a wireless router AP, and further, the step of performing a wireless connection performance test on the notebook includes:
501, the program starts.
Specifically, a program configured in advance for performing the test exists in a control machine for performing the test on the device to be tested, and the control machine may be a terminal device, such as a computer.
The program initializes the AP and DUT via wired communication, setting the WLAN channels and attenuation values to be tested 502.
Specifically, the control machine is connected with the AP and the DUT through wired communication, and after the initialization of both the AP and the DUT is completed, the channel analog attenuation value and the WLAN channel of the current test are configured first.
For example, the channel analog attenuation values to be tested in the test may be 48dB, 76dB, 86dB, and 96dB, the wireless channels in the test may be 1, 3, and 11, the channel analog attenuation values and the wireless channels are set at the beginning of the test, and then the wireless connection performance of the device to be tested is automatically tested directly according to the set channel analog attenuation values and the wireless channels.
The program controls the AP to send a connect command to establish a WLAN radio connection with the DUT 503.
Specifically, after the program controls the AP to configure the wireless channel, the DUT connects to the wireless channel corresponding to the AP according to the identifier of the wireless channel, for example, the IP address of the wireless channel.
The program sends back-off power values corresponding to the channel analog attenuation values to the AP and DUT 504.
Specifically, a corresponding relation table is configured in advance for the channel simulation attenuation value and the back-off power, and specifically, referring to the description of fig. 4, after determining the downlink channel back-off power corresponding to the AP and the uplink channel back-off power of the DUT, the program sends the downlink channel back-off power to the AP and sends the uplink channel back-off power to the DUT.
505, AP and DUT respectively read the calibrated power VS control word table in their respective memories, and transmit the back-off power.
Specifically, when the AP and the DUT are produced, the memories of the AP and the DUT have a power VS control word table, after the AP and the DUT receive power to be transmitted, the AP transmits downlink channel back-off power to the DUT according to a control word corresponding to the downlink channel back-off power in the power VS control word table, and the DUT transmits uplink channel back-off power to the AP according to a control word corresponding to the uplink channel back-off power in the power VS control word table.
WLAN throughput testing under this spatial attenuation is performed 506.
Specifically, according to the throughput rate of channel transmission performed by the AP and the DUT in the set channel analog attenuation value and the WLAN radio channel, a radio connection performance test is performed to determine whether the throughput rate during channel transmission meets the standard.
The program sends instructions to switch WLAN channels between AP and DUT and perform other channel tests 507.
Specifically, the wireless connection performance of the device to be tested under multiple wireless channels can be tested for one channel analog attenuation value, so that after one WLAN wireless channel is tested, the program sends an instruction to switch the WLAN wireless channel to the next WLAN wireless channel to be tested.
A WLAN throughput rate prediction of the spatial attenuation value is generated 508.
Specifically, for one channel simulation attenuation value, a throughput rate report under the channel simulation attenuation value is generated after the throughput rates of the devices to be tested under the corresponding multiple WLAN wireless channels are tested.
For example, the channel analog attenuation values to be tested are 48dB, 76dB and 86dB, the wireless channels to be tested are 1, 3 and 11, the throughput rates of the device under test under the wireless channels 1, 3 and 11 are respectively tested under the channel analog attenuation value of 48dB, and then the throughput rate report of the device under test under the channel analog attenuation value of 48dB is generated.
509, judging whether the reported value is reasonable, if not, stopping the test, and if so, continuing the test.
Specifically, after a round of testing is completed, whether the wireless connection between the AP and the DUT is disconnected or not is determined by transmitting data information through a channel in a channel process. If the data information is transmitted through the offline channel, an error condition occurs, for example, the numerical values are all 0, and the test needs to be stopped; if the channel transmits data information normally, the test is continued.
510, judging whether the test is finished or not, and if the test is not finished, continuing to test the next simulation space attenuation value; and generating a final test report after the test is finished, and finishing the test.
Specifically, whether the throughput rates of the devices to be tested under the multiple channel simulation attenuation values are all tested is determined according to the multiple channel simulation attenuation values set before the test, if yes, the test is finished, and a final test report is generated, and if not, the test is continued.
Therefore, the method for testing the wireless connection performance of the embodiment of the disclosure directly determines the uplink back-off power and the downlink channel back-off power of channel transmission according to the channel simulation attenuation value of the channel transmission between the wireless access device and the device to be tested, and can dynamically adjust the uplink channel back-off power and the downlink channel back-off power according to the channel simulation attenuation value to perform simulation of the function of an adjustable attenuator, so as to test the wireless connection performance under different channel simulation attenuation values, thereby realizing automatic test of the wireless connection performance, effectively simplifying the test process, and saving the cost.
