2, 3, and 4 illustrate an embodiment of the present invention by taking a real application scenario as an example:

FIG. 2 illustrates an example of determining, by using an access device at a location L1, a method for determining a signal strength coefficient of an access device at a location, as shown in FIG. 2, including the following steps:

Step 201: Record the number of STAs deployed in the resident place of the room;

Here, for an access device, a plurality of STA devices located at different locations that can access the access device are recorded, and the STA device may include STA devices such as a smart phone, a notebook, a PAD, and a printer, and each STA device corresponds to a different one. Device identification, for example, the smartphone is STA1, the notebook is STA2, the PAD is STA3, and the printer is STA4. Different locations can include living rooms, study rooms, balconies, bedrooms, and other places where you can surf the Internet. For example, STA1 is in the living room and STA2 is in the position. The study room, the location of STA3 is the bedroom, and the location of STA4 is the balcony.

Step 202: Connect the access device located at the location 1 with each STA device.

The WIFI function of the access device and the STA device is enabled, and the STA device in the different location is connected to the access device in the L1 location, and the device identifier of the STA device connected to the access device is recorded. Here, the STA devices accessing the access device are STA1, STA2, STA3, and STA4; the current location of the access device is marked as L1, that is, the location 1.

Step 203: Detect and save the WIFI signal strength of each STA.

Specifically, the access device in the L1 position sends a signal strength detection command to the STA1, the STA2, the STA3, and the STA4, and detects the signal strength of each device. Here, the access devices in the L1 position can be respectively received from STA1, STA2, STA3, and STA4. The received signal strengths are R11, R12, R13, and R14; and the signal strength of the STA device is detected, where the distances of STA1, STA2, STA3, and STA4 are different from each other, and the sizes of R11, R12, R13, and R14 are different. Can be different. Here, the access device defines the received signal strength of STAj accessing the access device located at location i as Rij.

Step 204, calculating and outputting a signal strength coefficient of position 1;

Here, before calculating the signal strength coefficient of the position 1, the weighting coefficient for calculating the signal strength coefficient is first obtained, wherein a weighting coefficient is set for each STA connected to the access device, and the weighting coefficient corresponding to STA1 is X1. The weighting coefficient corresponding to STA2 is X2, the weighting coefficient corresponding to STA3 is X3, and the weighting coefficient corresponding to STA4 is X4.

Here, the weighting coefficient may be set for each STA according to the frequency of use of each STA. Specifically, for the STAs with high frequency of use, the set weighting coefficient has a larger value; for STAs with low frequency of use, the weighting of the setting is set. The coefficient has a small value. For example, STA1 in the living room has a high frequency of use, and the weighting coefficient X1 is 5; the frequency of use in the study STA2 is second highest, and the weighting coefficient X2 is 4; the frequency of use of the STA3 in the bedroom is lower, and the weighting coefficient X3 is 3, located on the balcony. STA4 is used at a low frequency, and the weighting coefficient X4 is 2.

After obtaining the weighting coefficient, the access device calculates the signal strength coefficient of the location according to the obtained weighting coefficient and the signal strength of the corresponding STA device. At this time, the position of the access device is L1, and the intensity coefficient of the L1 position is defined as Y1. Where Y1=R11*X1+R12*X2+R13*X3+R14*X4.

It should be noted that the value of the weighting coefficient may be set according to a preset rule, wherein the preset rule may be set by the user according to the experience value.

3 is a schematic diagram of a flow of a method for selecting an optimal location of an access point, as shown in FIG. 3, including the following steps:

Step 301: Record a location where the access device can be placed;

Here, the labeling coordinates of the location where the access device can be placed in the room are identified, and the total number of positions of the recordable access device is n, wherein the i-th position where the access device is placed is recorded as Li.

Step 302, calculating a signal strength coefficient Yi of the access device placed at the Li position;

Specifically, starting with i=1, calculating the signal strength coefficient Y1 of the access device at the L1 to Ln position respectively: placing the access device at the L1 position, setting i=1, and adopting the method shown in FIG. Calculating the signal strength coefficient Y1 of the L1 position for a position determining the signal strength coefficient of the access device at the position, and calculating the signal corresponding to the L1 and L1 positions after calculating the signal strength coefficient Y1 of the access device at the L1 position The intensity coefficient Y1 is saved, and the value of i is increased by 1, and i=2. When the intensity coefficient of the i-th position Li is calculated, the intensity coefficient corresponding to Li is defined as Yi.

Step 303, determining whether i is less than or equal to n;

At this time, the value of i is compared with n to determine whether i is less than or equal to n. When i is less than or equal to n, step 304 is performed. Otherwise, step 302 is performed to calculate the signal strength of the access device placed at the Li position. The coefficient Yi, where i is greater than one.

It should be noted that, for an access device at each location, when the signal strength coefficient is calculated, the STA devices that are accessed by the access device are consistent, and for different access devices, a STA device The weighting coefficients are consistent.

Step 304: Generate a histogram of the signal strength coefficients at each position, output a histogram generated by the display, and select a position corresponding to the maximum value of the signal strength coefficient as the optimal position of the router;

Specifically, according to each position indication coordinate and its corresponding signal strength coefficient, a two-dimensional column chart is drawn and displayed, so that the user clearly recognizes the signal intensity coefficient of each position. And select the position corresponding to the maximum value of the signal strength coefficient as the optimal position for the access device, that is, the optimal position of the access point. At this time, the WIFI connection between the access device and each STA can reach an optimal state, so that each STA device in the room can access the Internet normally, and the WLAN network is further optimized.

In Figure 4, the uplink of the CPE is connected to the Internet through the SIM card dialing or Ethernet cable, and the downlink is connected to other STAs through the WIFI. Each STA performs network services through the CPE. The location of each STA is different, and the distance between the CPE and the CPE is different, which results in different WIFI signal strength between each STA and the CPE. For a STA with a weak WIFI signal, the STA has a weak WIFI signal, which seriously affects the speed and experience of the user using the STA to access the Internet. By adopting the method for selecting a mobile hotspot provided by the embodiment of the present invention, it is possible to find an optimal location for the access point device, and take into account the STAs used in the room, so that all STAs can smoothly perform network services.

In a practical application, the function and performance of the products of the access devices such as CPE and UFI are optimized by the method for selecting the optimal location of the access point provided by the embodiment of the present invention.

Place the CPE or UFI in a location in the room, enable its WIFI function, connect each STA to the CPE or UFI, and detect the WIFI signal strength of each STA. Then, according to the actual needs, a weighting coefficient is set for each STA, and finally the signal strength coefficient of the position is calculated, and so on, the signal strength coefficient at each position in the room is calculated, and a maximum value is selected from the CPE or UFI. The access device is placed in its corresponding location, so that the WIFI connection between each STA and the access device such as the CPE or UFI device is optimal, thereby ensuring that each STA can smoothly perform network services. Greatly improve the performance and user experience of access devices such as CPE and UFI products.
