Detailed Description

The principles and spirit of the present disclosure will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable one skilled in the art to better understand and practice the present disclosure and are not intended to limit the scope of the present disclosure in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The technical scheme of the present disclosure is further elaborated below with reference to the drawings and specific embodiments.

Fig. 1 is a schematic diagram showing the composition and structure of a wireless connection performance test system according to an embodiment of the present disclosure.

The wireless connection performance testing method of the embodiment of the disclosure can be implemented based on the wireless connection performance testing system shown in fig. 1. Referring to fig. 1, fig. 1 shows a schematic diagram of the composition structure of a wireless connection performance test system according to an embodiment of the present disclosure.

Fig. 2 is a schematic diagram illustrating an implementation flow of a wireless connection performance testing method according to an embodiment of the disclosure.

Referring to fig. 2, a wireless connection performance testing method according to an embodiment of the present disclosure at least includes: operation 201, receiving a channel simulation attenuation value of a test channel for performing wireless connection test on a device to be tested; operation 202, determining uplink channel back-off power and downlink channel back-off power for channel transmission between a device to be tested and a wireless access device according to a channel analog attenuation value of a test channel; operation 203, detecting a signal that wireless connection is successful, which is sent by the device to be detected; 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 uplink channel back-off power and downlink channel back-off 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 a wireless access device in response to a wireless connection performance test instruction; operation 206, determining the wireless connection performance test result of the device to be tested according to the channel transmission data information.

In operation 201, channel analog attenuation values of a test channel for wireless connection testing of a device under test are received.

Specifically, the channel simulation attenuation value of the current test can be received first, and the channel simulation attenuation value can be preconfigured through software or set according to specific actual requirements before the test starts.

For example, taking a device to be tested as a notebook computer, the channel simulation attenuation values are corresponding spatial attenuation values under different distances between the notebook computer and the wireless access device. 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 device.

Specifically, the channel simulation attenuation value can be determined according to the distance between the notebook computer and the wireless access device through a wireless space electromagnetic wave attenuation formula, and the specific formula is as follows:

wherein PathLoss represents a channel analog attenuation value, f represents a frequency of a radio frequency band, d represents a distance between a wireless access device and a device to be tested, and c represents a speed of light.

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 device to be tested under different distances with the wireless access device needs to be tested, the channel simulation attenuation value can be set directly according to the distances.

For example, taking the frequency of the wireless frequency band of the present test as 2.4Ghz as an example, the distances 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, 618 meters, and then the channel analog attenuation values corresponding to the distances obtained according to the above-mentioned wireless space electromagnetic wave attenuation formula are 46.0dB, 54.0dB, 60.0dB, 66.0dB, 69.5dB, 74.0dB, 80.0dB, 86.0dB, 95.8dB. And at the beginning of the test, configuring the obtained channel simulation attenuation values, 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 foregoing descriptions of the channel simulation attenuation value determining 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 in other applicable manners and manners, which are not specifically limited in this disclosure.

In operation 202, an uplink channel back-off power and a downlink channel back-off power for channel transmission between a device under test and a wireless access device are determined according to a channel analog attenuation value of a test channel.

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 the transmitting power of the device to be tested to the wireless access device, and the downlink channel transmission represents the transmitting power of the wireless access device to be tested to the wireless access device.

The device to be tested and the wireless access device have a certain distance, after the device to be tested and the wireless access device send the transmitting power, the transmitting power can be attenuated due to the existence of the distance, and the embodiment of the disclosure uses the analog channel attenuation value to represent the corresponding space attenuation value between the device to be tested and the wireless access device under different distances. Therefore, under the condition that the channel simulation attenuation value is received, the transmission power which is required to be transmitted after the transmission power transmitted by the device to be tested is attenuated and the transmission power which is required to be transmitted after the transmission power transmitted by the wireless access device is 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 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 fact that the adjustable attenuator breaks down and the like in the test process is effectively avoided.

The uplink channel back-off power is used to represent the transmission power which is required to be transmitted after the transmission power transmitted by the device to be tested is attenuated, and the downlink channel back-off power is used to represent the transmission power which is required to be transmitted after the transmission power transmitted by the wireless access device is attenuated.

In operation 203, a signal sent by the device under test that the wireless connection is successful is detected.

Specifically, since the performance test of the wireless connection 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 already 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 out a signal of successful wireless connection when the wireless access device is successfully connected with the device to be tested, and the wireless access device is proved to be successfully connected with the device to be tested when the signal of successful wireless connection is detected.

In operation 204, a wireless connection performance test instruction is sent to the device under test and the wireless access device, where the connection performance test instruction carries uplink channel back-off power and downlink channel back-off power for channel transmission between the device under test and the wireless access device.

Specifically, under the condition that the wireless access equipment and the equipment to be tested are successfully connected in a wireless mode, a connection performance test instruction can be sent to the wireless access equipment and the equipment to be tested, wherein the wireless connection performance test instruction carries the determined uplink channel back-off power and the determined 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 back-off power determined by the attenuation value of the test, and the downlink power in the channel transmission can be configured to be the downlink channel back-off attenuation value determined by the channel analog attenuation value of the test.

In operation 205, channel transmission data information of a test channel transmitted by a wireless access device in response to a wireless connection performance test instruction is received.

Specifically, after the throughput rate test instruction is sent to the device to be tested and the wireless access device, channel transmission data information generated in the process of channel transmission between the device to be tested and the wireless access device, which is sent by the wireless access device, can be received in real time.

In operation 206, a wireless throughput test result of the device under test is determined according to the channel transmission data information.

Specifically, the channel transmission information includes throughput rate, and the wireless connection performance can be determined according to the throughput rate, so that a wireless throughput rate test result of the device to be tested can be obtained according to the throughput rate shown by the channel transmission information.

Fig. 3 is a schematic diagram of an implementation flow of determining a back-off power according to an embodiment of the disclosure.

In an embodiment of the present disclosure, in operation 201, determining uplink channel back-off power and downlink channel back-off power of channel transmission according to the channel attenuation value of the present test includes:

in operation 301, a power backoff value is determined according to the attenuation value of the current test channel and a preset standard attenuation value.

Specifically, in the process of testing the wireless connection performance of the device to be tested, the transmitting 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 the difference between the preset standard attenuation value and the channel attenuation value tested at this time.

For example, the fixed distance between the test antenna and the device under test is 2 meters, and the frequency of the wireless channel is 2.4GHz, that is, the preset standard attenuation value is 46 dB. The analog attenuation values of the channels tested at this time can be 48dB, 76dB, 86dB, 96dB and the like, and the corresponding power back-off values tested at this time 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 frequency of the test in the actual test process.

And 302, determining the uplink channel back-off power of the device to be tested according to the maximum transmitting power of the device to be tested and the power back-off value.

Specifically, when the device to be tested performs wireless performance, after the device to be tested is in wireless connection with the wireless access device, the device to be tested can send unattenuated maximum transmitting power supported by the device to the wireless access device.

Further, the maximum transmitting power supported by the device to be tested and the power back-off value are added to obtain the transmitting power which the device to be tested should transmit in the test process, namely the back-off power of the uplink channel.

And operation 303, determining the downlink channel back-off power of the wireless access device according to the maximum transmitting power of the wireless access device to be accessed and the power back-off value.

Specifically, the determining process of the downlink channel back-off power may be the same as or similar to the determining process of the uplink channel back-off power, that is, the calculation performed by the maximum transmission power supported by the wireless access device is not described herein.

In a specific application example of this embodiment of the disclosure, the uplink channel back-off power and the downlink channel back-off power of the channel transmission may be determined according to the channel attenuation value and the preset power table of the current test.

Specifically, a plurality of channel simulation attenuation values may be determined that require testing of the device under test. Further, a plurality of rollback values corresponding to the channel simulation attenuation values are calculated through the channel simulation attenuation values, and a plurality of uplink channel rollback powers of the corresponding equipment to be tested and a plurality of downlink channel rollback powers of the wireless access equipment are calculated according to the rollback values. And finally, establishing a table of the channel simulation attenuation value, the calculated back-off value, the uplink channel back-off power of the equipment to be tested and the downlink channel back-off power of the wireless access equipment, and obtaining a preset power table for showing the corresponding relation between the channel simulation attenuation value, the uplink channel back-off power of the equipment to be tested and the downlink channel back-off power of the wireless access equipment.

Further, a preset power meter is configured in advance, and further after receiving the channel analog attenuation value, the uplink channel back-off power and the downlink channel back-off power of the channel transmission can be determined directly according to the preset power meter.

For example, assume that the device to be tested is a notebook computer, the wireless access device is a wireless router, the fixed distance between the test antenna of the wireless access device and 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 the wireless frequency band is 2.4GHz and the fixed distance between the test antenna and the equipment to be tested is 2 meters, the preset standard attenuation value is 46dB, and the corresponding power back-off values of the test can be obtained to be-2, -30, -40 and-50 under the assumption that the channel simulation attenuation values of the test are 48dB, 76dB, 86dB, 96dB and the like respectively. The maximum transmitting power of the notebook computer at 2.4GHz is generally 17dB, the maximum transmitting power of the wireless router at 2.4GHz is generally 20dB, so that the uplink channel back-off power of the corresponding notebook computer can be obtained through the back-off values to be 18dB, -10dB, -20dB and-30 dB respectively, and the downlink channel back-off power of the corresponding wireless router is 15dB, -13dB, -23dB and-33 dB respectively.

Further, the calculated channel analog attenuation value, the calculated back-off value, the calculated uplink channel back-off power of the device to be tested, and the calculated downlink channel back-off power of the wireless access device may be represented by a preset power table as shown in the following table one.

List one

Channel simulation attenuation values	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 an 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 device responds to the wireless throughput rate test instruction to send downlink channel back-off power to the device to be tested, and the uplink channel transmission data information is generated in the process that the device to be tested responds to the wireless throughput rate test instruction to send uplink channel back-off power to the wireless access device.

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 a process of transmitting uplink channel back-off power to the wireless access device by the device to be tested, and the downlink channel transmission indicates a process of transmitting downlink channel back-off power to the device to be tested by the wireless access device.

Further, channel transmission data information of channel transmission can be generated in the channel transmission process of the device to be tested and the wireless access device, and the channel transmission data information comprises uplink channel transmission data information generated in the uplink channel transmission process and downlink channel transmission data information generated in the downlink channel transmission process.

In an embodiment of the present disclosure, when receiving a radio throughput rate test instruction, a radio access device may determine, according to downlink channel back-off power carried in the radio throughput rate test instruction, a downlink control word configured by the radio access device and used for triggering transmission of the downlink channel back-off power, so as to transmit the downlink channel back-off power to a device to be tested through triggering of the downlink control word.

In an embodiment of the disclosure, when receiving the radio throughput rate test instruction, the device to be tested can determine an uplink control word used for triggering and sending the uplink channel back-off power in its configuration according to the uplink channel back-off power carried in the radio throughput rate test instruction, so as to send the uplink channel back-off power to the radio access device through triggering of the uplink control word.

Specifically, the control word corresponding to each power transmitted by the device to be tested can be obtained through radio frequency calibration before the device to be tested leaves the factory, so that a power control word list of the device to be tested can be generated, the power control word list is configured in the device to be tested before leaving the factory, when the device to be tested is to transmit a certain power, the control word corresponding to the power can be determined to be transmitted according to the power control word list, and then the control word triggers the device to be tested to transmit the corresponding power. It should be noted that, the process of obtaining the control word from the power is performed before leaving the factory, and all the schemes of determining the control word corresponding to the power from the power, which are common in the art, can implement the scheme of obtaining the control word in the present disclosure, so that the description thereof is omitted here.

Further, the procedure of the wireless access device and the device to be tested is the same, and will not be described in detail here.

In an embodiment of the present disclosure, the operation 206 specifically includes: judging whether the wireless throughput rate shown by the channel transmission data information accords with 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 accords with 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 accord with 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. For the uplink throughput rate and the downlink throughput rate of different channel simulation attenuation values, corresponding throughput rate standards exist in the industry. And directly comparing the throughput rate shown by the channel transmission data information with the throughput rate standard, if the wireless throughput rate meets the throughput rate standard, judging that the wireless connection performance test result of the equipment to be tested is qualified, and if the wireless throughput rate does not meet the throughput rate standard, judging that the wireless connection performance test result is unqualified.

Referring to fig. 5, in a specific application example of the embodiment of the disclosure, the device to be tested is a notebook computer DUT, the wireless access device is a wireless router AP, and further, the step of performing a wireless connection performance test on the notebook computer includes:

501, the program is started.

Specifically, a program for performing a test configured in advance exists in a control board for performing a test on a device to be tested, and the control board may be a terminal device, for example, a computer.

The program initializes the AP and DUT via wired communication and sets the WLAN channel and attenuation values that need 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 simulation attenuation value and the WLAN channel of the test are firstly configured.

For example, the channel analog attenuation values to be tested in the test can be 48dB, 76dB, 86dB and 96dB, the radio frequency channels in the test can be 1, 3 and 11, the channel analog attenuation values and the radio frequency channels are set at the beginning of the test, and then the radio connection performance of the device to be tested is automatically tested directly according to the set channel analog attenuation values and the radio frequency channels.

503, the program controls the AP to make the AP send a connection command to establish a WLAN radio connection with the DUT.

Specifically, after the program controls the AP to configure the radio channel, the DUT connects with the radio channel corresponding to the AP according to the identification of the radio channel, for example, the IP address of the radio channel.

At 504, the program sends back-off power values corresponding to the channel analog attenuation values to the AP and DUT.

Specifically, a corresponding relation table is configured in advance for the channel simulation attenuation value and the back-off power, 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, the ap and the DUT respectively read the calibrated power VS control word table in their respective memories and send back-off power.

Specifically, when the AP and the DUT are produced, a power VS control word table is arranged in a storage of the AP and the DUT, 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 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 uplink channel back-off power in the power VS control word table.

At 506, WLAN throughput testing under this spatial attenuation is performed.

Specifically, according to the set channel simulation attenuation value of the AP and the DUT and the throughput rate of the WLAN wireless channel for channel transmission, the wireless connection performance test is carried out, and whether the throughput rate in the channel transmission process meets the standard is judged.

507, program sends instructions to switch WLAN channels of AP and DUT, and test other channels.

Specifically, the wireless connection performance of the device to be tested under a plurality of wireless channels can be tested according to the analog attenuation value of one channel, so that after testing one WLAN wireless channel, the program sends an instruction to switch the WLAN wireless channel to the next WLAN wireless channel to be tested.

508, generating WLAN throughput rate observations of the spatial attenuation values.

Specifically, for a channel simulation attenuation value, after testing the throughput rates of the devices to be tested under the corresponding multiple WLAN radio channels, throughput rate measurement report under the channel simulation attenuation value is generated.

For example, the analog attenuation values of the channels 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 tested under the analog attenuation values of the channels of 48dB, and then the throughput rate test report of the device under test under the analog attenuation values of the channels of 48dB is generated.

509, judging whether the report value is reasonable or not, if not, stopping the test, and if so, continuing the test.

Specifically, after a round of testing is completed, data information is transmitted through a channel in the channel process to judge whether the wireless connection between the AP and the DUT is disconnected. If the data information is transmitted by the dropped channel, error conditions occur, for example, the values are all 0, and the test is required to be stopped; and if the channel transmission data information is normal, continuing the test.

510, judging whether the test is completed or not, and continuing to test the next simulated space attenuation value if the test is not completed; and generating a final test report after completion, and completing the test.

Specifically, determining whether the throughput rates of the device to be tested under the multiple channel simulation attenuation values are all tested according to the multiple channel simulation attenuation values set before the test, ending the test to generate a final test report if the test is all finished, and continuing the test if the test is not finished.
