The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Fig. 1 is a schematic structural diagram of a testing system for a WIFI function provided in a first embodiment of the present invention, and as shown in fig. 1, the testing system for a WIFI function provided in the embodiment of the present invention includes a control device 1, a wireless testing device 2, a flow simulation device 3, and a device under test 4, where:

the control device 1 is respectively in communication connection with the wireless testing device 2, the flow simulation device 3 and the tested device 4, the flow simulation device 3 is respectively in wired communication connection with the tested device 4 and the wireless testing device 2, and the tested device 4 is in wireless communication connection with the wireless testing device 2.

The WIFI function of the device under test 4 is tested by testing each frequency band of each antenna of the device under test 4, and when the test result of each frequency band of each antenna of the device under test 4 is passed, the device under test 4 passes the WIFI function test. The working process of the test system for the WIFI function provided in the embodiment of the present invention is described below by taking an example of setting that the device under test 4 operates in an access point mode (AP mode for short) and testing one frequency band of one antenna of the device under test 4. When the plurality of antennas of the device under test 4 correspond to the same frequency band, only one frequency band of one currently tested antenna is enabled, and the other antennas of the same frequency band are turned off.

The control apparatus 1 sends a first control instruction to the device under test 4, so that the device under test 4 operates in the AP mode and configures a unique corresponding Service Set Identifier (SSID) for the device under test 4. Isolation of the device under test 4 in the open air domain is achieved by configuring the device under test 4 with a unique SSID such that the SSID of each device under test 4 in the open air domain is unique. The first control instruction is set according to actual needs, and the embodiment of the present invention is not limited.

The control device 1 sends a second control command to the wireless testing device 2 to enable the wireless testing device 2 to operate in a station mode (STA mode for short), and enable the wireless testing device 2 to access the set frequency band of the set antenna of the device under test. The second control instruction is set according to actual needs, and the embodiment of the present invention is not limited.

The wireless test device 2 checks whether to establish a WIFI wireless communication connection with the set frequency band of the set antenna of the device under test 4, and if the WIFI wireless communication connection is successfully established, returns information of successful connection to the control device 1, and if the WIFI wireless communication connection cannot be established within a specified time, returns information of failed connection to the control device 1.

If the control device 1 receives the information of successful connection, a third control instruction is sent to the flow simulation device 3, so that the flow simulation device 3 sends a simulation message to the tested device 4 in a wired communication mode, and sends message simulation configuration information to the wireless test device 2, wherein the message simulation configuration information corresponds to the simulation message, and the message structure and the message sending configuration parameters of the simulation message are specified. The control apparatus 1 may determine that the test for setting the antenna and setting the frequency band fails if the information of the connection failure is received. The simulation message is preset and can include fingerprint data, so that the receiving end can analyze and count the received data packet conveniently. The fingerprint data is a section of specially coded byte stream (usually 16 to 20 bytes), which contains stream number, message sequence number, timestamp, magic number identifier, CRC check code, etc., when the receiving end receives the message, the receiving end can compare the magic number identifier with the CRC check code, and after confirming that the message is the message sent by the flow simulation device 3, the parameters of the packet loss rate, the average delay of the message, etc. are counted through the stream number, the message sequence number and the timestamp. The third control instruction is set according to actual needs, and the embodiment of the present invention is not limited.

For example, the wireless testing device 2 compares the simulation message included in the first forwarding information with the message simulation configuration information, and obtains a packet loss rate through statistics, the wireless testing device 2 measures the received power of the first forwarding information and calculates an average value as a wireless power when receiving the first forwarding information, the wireless testing device 2 calculates and calculates the message average delay of the first forwarding information when receiving the first forwarding information, and the wireless testing device 2 calculates and obtains an Error Vector Magnitude (EVM) and a negotiation rate according to the first forwarding information. The test result for setting the frequency band of the antenna may include one or more first test parameters, where the first test parameters are packet loss rate, wireless power, packet average delay, error vector magnitude, or negotiation rate.

The control device 1 may determine whether the set antenna and the set frequency band pass the test according to the test result of the set frequency band of the set antenna reported by the wireless test device 2. For example, the test result of the set frequency band of the set antenna received by the control device 1 includes the packet loss rate, the wireless power, and the average packet delay, and if it is determined that the packet loss rate is within the corresponding set range, the wireless power is within the corresponding specified range, and the average packet delay is smaller than the delay threshold, it is determined that the set antenna and the set frequency band pass the test. The setting range corresponding to the packet loss rate, the designated range corresponding to the wireless power, and the delay threshold are set according to actual experience, which is not limited in the embodiments of the present invention.

When the plurality of antennas of the device under test 4 correspond to the same frequency band, only one frequency band of one currently tested antenna is enabled, and the other antennas of the same frequency band are turned off.

The control device 1 sends a fourth control instruction to the wireless testing device 2 to make the wireless testing device 2 work in the AP mode and configure the wireless testing device 2 with a unique corresponding SSID. Isolation of the wireless test device 2 in the open air domain is achieved by configuring the wireless test device 2 with a unique SSID such that the SSID of the wireless test device 2 in the open air domain is unique. The fourth control instruction is set according to actual needs, and the embodiment of the present invention is not limited.

If the control device 1 receives the information of successful connection, a sixth control instruction is sent to the flow simulation device 3, so that the flow simulation device 3 sends a simulation message to the tested device 4 in a wired communication mode, and sends message simulation configuration information to the wireless test device 2, wherein the message simulation configuration information corresponds to the simulation message, and the message structure and the message sending configuration parameters of the simulation message are specified. The control apparatus 1 may determine that the test for setting the antenna and setting the frequency band fails if the information of the connection failure is received. The simulation message is preset and can include fingerprint data, so that the receiving end can analyze and count the received data packet conveniently. The sixth control instruction is set according to actual needs, and the embodiment of the present invention is not limited.

After receiving the simulation message in the wired communication manner, the device under test 4 forwards the simulation message to the wireless testing apparatus 2 in the WIFI communication manner. The wireless testing device 2 may receive the first forwarding information sent by the device under test 4 and the message simulation configuration information sent by the control device 1, then obtain a test result of the set frequency band of the set antenna of the device under test 4 based on the first forwarding information and the message simulation configuration information, and then report the test result of the set frequency band of the set antenna to the control device 1.
