[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1

[0045] Please refer to Figure 1 , Figure 1 A flowchart of a wireless network card calibration method provided by an embodiment of the present invention includes steps 101 to 103, which are specifically as follows:

[0046] Step 101: Setting a cumulative flag, and counting consecutive and identical API instruction factors according to the cumulative flag; the instruction factors include channel value, bandwidth value, power value and antenna port value;

[0047] In this embodiment, the wireless network card is powered to enter the calibration mode, and a cumulative flag "API-SUM" is set in the calibration program. The cumulative flag is used to count consecutive identical API instruction factors, that is, to count the number of times the calibration software repeatedly inputs the same API instruction. The API instruction factors include: channel, bandwidth, power, and antenna port, which are recorded in the calibration program as (CHIdx: m, BandIdx: n, PowerIdx: x, AntIdx: y).

[0048] In this embodiment, when one API instruction is detected, API-SUM=1 is counted, and when API instructions with exactly the same factors are detected continuously, API-SUM=n is accumulated.

[0049] Please refer to Figure 2 , Figure 2 A schematic diagram of cumulative flag bit statistics of the wireless network card calibration method provided by an embodiment of the present invention.

[0050] In this embodiment, the calibration software inputs API instructions to the wireless network card through an interface such as telnet or a serial port. After receiving the API instructions, the wireless network card will feed back the corresponding echo information to the log of the main program, where the format of the echo information is: MtCmdSetTxPowerCtrl:chIdx:36,BandIdx:0,PowerIdx:42,AntIdx:1.

[0051] In this embodiment, the cumulative flag is used to detect the echo information of the API instruction. When any API instruction echo information is detected, the count is 1; when two identical echo information are detected consecutively, the count is 2; when two identical echo information are detected but there is other different echo information in between, the count is still 1.

[0052] Step 102: setting an initial value of the power factor according to the scheme of the wireless network card, and adjusting the hardware parameters of the wireless network card according to the calibration software and the API instruction;

[0053] In this embodiment, the initial value of the power factor is set according to the scheme of the wireless network card, and the hardware parameters of the wireless network card are adjusted according to the calibration software and the API instruction, including:

[0054] Set the initial values ​​of various hardware parameters according to the API instructions, and set the corresponding initial value of the power factor according to the wireless network card solution;

[0055] The calibration software adjusts the hardware parameters of the wireless network card one by one according to the API instruction and the initial values ​​of the hardware parameters and the initial value of the power factor, wherein the hardware parameters include channel, bandwidth, power and antenna port.

[0056] In this embodiment, the initial values ​​and power factors of various hardware parameters in the calibration software are set according to the API instructions, so that the wireless network card is calibrated according to the initial values ​​and the power factors.

[0057] In this embodiment, the power factor sets different initial values ​​according to different WIFI schemes. Specifically, the calibration software sets the initial values ​​of the calibration parameters through API instructions: AntIdx: A1, BandIdx: B1, chIdx: C1, PowerIdx: 42, where PowerIdx is the power factor.

[0058] In this embodiment, the initial value of the power factor is set according to the scheme of the wireless network card, and the hardware parameters of the wireless network card are adjusted according to the calibration software and the API instruction, and further includes:

[0059] Controlling the output power of the wireless network card according to the calibration software and the first API instruction, and obtaining the power of the wireless network card according to the detection instrument;

[0060] If the detection instrument fails to obtain the power of the wireless network card, the first API command is repeatedly input until the detection instrument successfully obtains the wireless network card or the number of command inputs reaches a preset threshold, and calibration continues.

[0061] In this embodiment, when the output power of the wireless network card is controlled by inputting an API instruction and the detection instrument cannot detect the power, the same API instruction is repeatedly input 10 times.

[0062] Step 103: Obtain the power value corresponding to the wireless network card after each hardware parameter is adjusted, and perform power calibration on the wireless network card according to the power value, power factor and cumulative flag value.

[0063] In this embodiment, the step of obtaining the power value corresponding to the wireless network card after each hardware parameter is adjusted, and performing power calibration on the wireless network card according to the power value, power factor and cumulative flag value includes:

[0064] After each adjustment of a first parameter of the wireless network card, a power value corresponding to the wireless network card is obtained; the first parameter is a currently adjusted hardware parameter;

[0065] If the power value is not within the power factor range, and continue to adjust the first parameter again according to the API instruction;

[0066] If the power value is within the power factor range, the adjustment of the first parameter is stopped and the next hardware parameter is calibrated.

[0067] In this embodiment, the calibration software adjusts the hardware parameters of the network card through API instructions, such as channel, bandwidth, power, antenna port, etc., so that the wireless network card outputs corresponding power. At the same time, the calibration software detects the corresponding power value by controlling the instrument, thereby performing power calibration according to the preset target power.

[0068] In this embodiment, the number of antenna ports of the wireless network card is A1-An, the number of bandwidths is B1-Bn, and the number of channels is C1-Cn.

[0069] Please refer to Figure 3 and Figure 4 , Figure 3 A schematic diagram of the distribution of hardware parameters of a wireless network card for the wireless network card calibration method provided by an embodiment of the present invention; Figure 4 A calibration flow diagram of a wireless network card calibration method provided by an embodiment of the present invention.

[0070] In this embodiment, the calibration software sets the initial values ​​of the calibration parameters through API instructions: AntIdx: A1, BandIdx: B1, chIdx: C1, power factor: PowerIdx: 42.

[0071] In this embodiment, after issuing the API instruction, the calibration software reads the power detection value of the test instrument, and when the detection power is within the target power range, the calibration of this parameter is ended and the calibration of the next channel is transferred. When the detection power is not within the target power range, for example, when the detection power is not within the target power range after inputting an API instruction, the power factor is: PowerIdx: 42, and then the power factor is adjusted to PowerIdx: 43, the parameters of the wireless network card are calibrated again to adjust the power factor so that the detection power is within the target power range.

[0072] The calibration is completed when the antenna ports, bandwidth quantity and channels of all wireless network cards are calibrated.

[0073] In this embodiment, after if the power value is not within the power factor range and continuing to adjust the first parameter again according to the API instruction, the method includes:

[0074] When the accumulated mark value reaches a preset threshold, the wireless network card is controlled to stop outputting power.

[0075] In this embodiment, when the main program detects the corresponding API instruction, the cumulative flag bit API-SUM starts to count, and when the cumulative flag bit API-SUM reaches a preset threshold, the wireless network card is controlled to stop outputting power.

[0076] In this embodiment, when API-SUM=5, the main program sends the following command to the wireless network card:

[0077] [166.426476]SetATE:Arg=TXSTOP

[0078] [166.438345]SetATE:Arg=APSTOP

[0079] In this embodiment, the functions of the instruction SetATE:Arg=TXSTOP and the instruction SetATE:Arg=APSTOP are to stop the wireless network card from outputting power, and then the calibration software starts the next calibration.

[0080] In this embodiment, a cumulative mark bit API-SUM is introduced into the wireless network card main program, and cooperates with the calibration software program to implement the input of SetATE:Arg=TXSTOP, SetATE:Arg=APSTOP instructions when the network card driver is stuck, so that the wireless network card can output the corresponding power and continue calibration.

[0089] Controlling the output power of the wireless network card according to the calibration software and the first API instruction, and obtaining the power of the wireless network card according to the detection instrument;

[0090] If the detection instrument fails to obtain the power of the wireless network card, the first API command is repeatedly input until the detection instrument successfully obtains the wireless network card or the number of command inputs reaches a preset threshold, and calibration continues.
