FIG. 1 is a schematic illustrating a system according to an embodiment of the present disclosure. Referring to FIG. 1, the system includes a terminal 11, a control device 12, a first wireless router 13, and one or more second wireless routers 14. In particular, through an application installed in the terminal 11, the control device 12 may connect to a wireless network provided by the first wireless router 13 whose communication quality may be improved using the embodiments of the present disclosure.

In some embodiments, the control device 12 may detect the wireless signal corresponding to each channel that the wireless router may be connected to, subsequently, the control device 12 may obtain the number of wireless access points on each channel and the wireless signal strengths of the wireless access points, where the wireless signal strength may be the signal strength of the wireless signal transmitted by the wireless access points at the control device 12 (e.g., measured/detected by the control device 12) , so the channel quality of each channel may be determined. Based on the channel quality of each channel, the control device 12 may determine the channel with the best channel quality as a target channel. If the current working channel of the first wireless router 13 is different from the target channel, an identifier identifying the target channel with the best channel quality may be sent to the first wireless router 13, so the first wireless router 13 may switch the current working channel to the target channel, thereby improving the communication quality of the first wireless router 13.

The control method of the wireless router will be described in detail below in the following embodiment.

FIG. 2 is a signal flowchart of a method for controlling a wireless router according to an embodiment of the present disclosure. As shown in FIG. 2, the control method of the present embodiment includes the following steps:

Step S101, obtaining the channel quality of each channel that the wireless router may be connected to using the control device based on the number of wireless access points on the channel and the wireless signal strength of each wireless access point, where the wireless signal strength may be the signal strength of the wireless signal transmitted by the wireless access points at the control device.

Step S102, determining the target channel from each channel based on the channel quality of each channel, where the target channel may be the channel with the best channel quality among the channels.

Step S103, sending the channel switching instruction from the control device to the target wireless router if the working channel of the target wireless router is different from the target channel, where the channel switching instruction may include the identifier of the target channel and the channel switching instruction may be used to instruct the target wireless router to switch the working channel to the target channel.

Step S104, switching the current working channel to the target channel based on the identifier of the target channel.

More specifically, the control device of the present embodiment may be the control device 12 of FIG. 1, and the target wireless router may be the first wireless router 13 of FIG. 1.

Further, the target wireless router in the present embodiment may be a wireless WiFi router. The wireless router may include an access point (AP) , which may be used to convert the wired network into a wireless network and transmit wireless signals. At this point, the identifier of the wireless router may also be the identifier of the wireless access point. Furthermore, the wireless access point may also work as an independent node, which may not have any routing function.

Prior to Step S101, the control device may connect to the wireless network provided by the target wireless router through the application installed in the terminal.

The specific process in which the control device accesses the wireless network provided by the target wireless router may include: the user provides the target wireless router’s management account and password to the terminal; the terminal sends the management account and password of the target wireless router to the control device after receiving the management account and password, so the control device may access the wireless network provided by the target wireless router; and the control device accesses the wireless network provided by the target wireless router based on the IEEE 802.11 b/g/n WiFi protocol. Further, the control device may need to store the management account and password of the target wireless router to control the target wireless router through the Hyper Text Transfer Protocol (HTTP) communication mode.

Step S101, obtaining the channel quality of each channel that the wireless router may be connected to using the control device based on the number of wireless access points on the channels and the wireless signal strength of each wireless access point, where the wireless signal strength is the signal strength of the wireless signal transmitted by the wireless access points at the control device.

More specifically, prior to Step S101, each wireless signal corresponding to each channel may need to be detected to obtain the number of wireless access points on each channel and the wireless signal strength of each wireless access point on each channel, where the wireless signal strength is the signal strength of the wireless signal transmitted by the wireless access point at the control device.

Further, channels may also be referred to as tunnels and frequency bands, which is the data signal transmission passage using wireless signals as the transmission carrier. Furthermore, a wireless router may correspond to a plurality of channels. For example, a wireless router may correspond to 13 channels, where each channel may correspond to a different center of frequency. For example, the 13 channels corresponding to the wireless router may be 13 channels obtained by dividing the 2.4GHz band into 13 frequency ranges, where Channel 1’s center of frequency may be 2412MHz, and the frequency range may be 2401～2423MHz; Channel 2’s center of frequency may be 2417MHz, and the frequency range may be 2406～2428MHz; Channel 3’s center of frequency may be 2422MHz, and the frequency range may be 2411～2433MHz; Channel 4’s center of frequency may be 2427MHz, and the frequency range may be 2416～2438MHz; Channel 5’s center of frequency may be 2432MHz, and the frequency range may be 2421～2443MHz; Channel 6’s center of frequency may be 2437MHz, and the frequency range may be 2426～2448MHz; Channel 7’s center of frequency may be 2442MHz, and the frequency range may be 2431～2453MHz; Channel 8’s center of frequency may be 2447MHz, and the frequency range may be 2436～2458MHz; Channel 9’s center of frequency may be 2452Hz, and the frequency range may be 2441～2463MHz; Channel 10’s center of frequency may be 2457MHz, and the frequency range may be 2446～2468MHz; Channel 11’s center of frequency may be 2462MHz, and the frequency range may be 2451～2473MHz; Channel 12’s center of frequency may be 2467MHz, and the frequency range may be 2456～2478MHz; and Channel 13’s center of frequency may be 2472MHz, and the frequency range may be 2461～2483MHz. As can be seen, there is no frequency overlap between Channel 1, Channel 6, and Channel 13, that is, if wireless router A’s working channel is Channel 1, and wireless router B’s working channel is channel 6, then the wireless router A and wireless router B will not interfere each other.

In particular, if a wireless router’s working channel is the abovementioned Channel 1, then the frequency of the wireless signal transmitted by the wireless router will be between 2041～2423MHz. In addition, if the working channel of the wireless router is the other abovementioned channel, then the frequency of the wireless signal transmitted by the wireless router will match the frequency band corresponding to the respective channel.

Correspondingly, detecting the wireless signal corresponding to each channel may be detecting the wireless signal whose frequency corresponds to a corresponding channel. Further, the information in the wireless signal may include: an identifier identifying the wireless access point that transmitted the wireless signals (if the wireless access point is located in the wireless router, then the identifier of the wireless access point is the identifier of the wireless router) ; a Media Access Control (MAC) address of the wireless access point that transmitted the wireless signals (if the wireless access point is located in the wireless router, then the MAC address of the wireless access point is the MAC address of the wireless router) ; and a Received Signal Strength Indication (RSSI) , where the RSSI may be used to indicate the wireless signal strength of the wireless access point, that is, the strength when the wireless signal transmitted by the wireless access point reaches the signal receiving device. For example, if the device receiving the signal is the control device, then the RSSI may indicate the wireless signal strength at the control device, in other words, the signal strength of the wireless signal received by the control device.

For example, when the control device detects a wireless signal corresponding to Channel 1, the control device may detect the wireless signal in the frequency range of 2401～2423MHz, and count the number of identifiers of the wireless access points carries in each wireless signal between 2401～2423MHz and the corresponding RSSI. Further, if the number of identifiers carried by the wireless access points in each wireless signal with the frequency in the range of 2401～2423MHz is two, then Channel 1 may include two wireless access points. Furthermore, if the two wireless access points are both wireless access points of the wireless router, then number of wireless routers whose working channel is Channel 1 equals two, such as wireless router C and wireless router D. In addition, RSSI _C may represent the wireless signal strength transmitted by the wireless router C (or the wireless access point C on wireless router C) at the control device, that is, the strength of the wireless signal transmitted by the wireless router C received by the control device, in other words, the wireless signal strength of the wireless router C or the wireless signal strength of the wireless access point C. Further, RSSI _D may represent the wireless signal strength transmitted by the wireless router D (or the wireless access point D on wireless router D) at the control device, that is, the strength of the wireless signal transmitted by the wireless router D received by the control device, in other words, the wireless signal strength of the wireless router D or the wireless signal strength of the wireless access point D.

For example, if the wireless signal with a frequency of 2418MHz is detected and the wireless signal carries the identifier of the wireless router C, then the RSSI carried in the wireless signal may be the wireless signal strength (RSSI _C) when the wireless signal transmitted by the wireless router C reaches the control device.

Through the method mentioned above, the number of wireless access points on Channel 1 and the wireless signal strength of each wireless access point on Channel 1 may be obtained (that is, the signal strength of the wireless signal transmitted by each wireless access point on Channel 1 at the control device may be obtained) .

Those skilled in the art will appreciate that the farther the control device is from the wireless router, the weaker the strength of the wireless signal transmitted by the wireless router and received by the control device will become, and the RSSI will be smaller.

Using the same method described above, the wireless signals corresponding to other channels may be detected, and the number of wireless access points on other channels and the signal strength of the wireless signals transmitted by the wireless access points on other channels at the control device may be obtained as well. Further, after obtaining the number of wireless access points on each channel and the signal strength of the wireless signals transmitted by the respective wireless access points on each channel at the control device, the channel quality of each channel may be determined.

More specifically, obtaining the channel quality of each channel that the wireless router may be connected to using the control device based on the number of wireless access points on the channels and the wireless signal strength of each wireless access point, where the wireless signal strength is the signal strength of the wireless signal transmitted by the wireless access points at the control device may include:

For each channel, the control device may obtain a channel quality indicator value that may be used to indicate the channel quality of the channel. In particular, the channel quality indicator value of a channel may be obtained based on the sum of the wireless signal strengths of all the wireless access points on the corresponding channel and the number of the wireless access points of the corresponding channel. Further, the channel quality indicator value Q may be obtained using the following equation:

Qi=RSSI ₁ +…+RSSI _c+ …+ RSSI _C

Where Q _i is the channel quality indicator value of the i ^th channel, RSSI _c is the signal strength of the wireless signal transmitted by the c ^th wireless access point on the i ^th channel at the control device, and C is the number of wireless access points on the i ^th channel.

More specifically, determining the target channel from each channel based on the channel quality of each channel, where the target channel may be the channel with the best channel quality among the channels may include: determining the target channel from each channel based on the channel quality indicator value of each channel, where the target channel may be the channel with the best channel quality among the channels.

In particular, the lower the channel quality indicator value Q, the better the channel quality, that is, the lowest channel quality indicator value Q may be selected from the obtained channel quality indicator values, and the channel corresponding to the lowest channel quality indicator value Q may be the channel with the best channel quality, that is, the target channel.

More specifically, the control device may determine whether the working channel of the target wireless router is the same as the target channel. If they are different, the channel switching instruction may be sent to the target wireless router, where the channel switching instruction may include the identifier of the target channel, and the channel switching instructor may be used to instruct the target wireless router to switch the working channel to the target channel.

In some embodiments, the channel switching instruction may be in the form of a wireless channel switching list, where the identifier of the target channel may be included in the wireless channel switching list.

Further, in the process of networking the control device with the target wireless router, that is, in the process of connecting the control device to the wireless network provided by the target wireless router, the control device may synchronize the working channel with the target wireless router to determine the working channel of the target wireless router.

Furthermore, the specific process of synchronizing the channels may refer to the procedure specified in the IEEE 802.11 b/g/n wireless protocol, which will not be described herein.

More specifically, after receiving the channel switching instruction, the target wireless router may switch the current working channel to the target channel based on the identifier of the target channel in the channel switching instruction.

Furthermore, the specific process of switching the channels may refer to the procedure specified in the IEEE 802.11 b/g/n wireless protocol, which will not be described herein.

The embodiments of the present disclosure provide a method that allows the wireless router to select the channel with the best quality out of all available channels. If the wireless router’s current working channel is not the channel with the best quality, a channel switching instruction may be sent to the wireless router to switch the working channel of the wireless router to the channel with best quality, thereby improving the communication quality of the wireless router.

Those skilled in the art will appreciate that the steps mentioned above may be performed in a cycle, for example, periodically at a predetermined time interval. More specifically, the process may be: at a predetermined time interval periodically detecting the wireless signal corresponding to each channel, and obtaining the number of wireless access points on each channel and the signal strength of the wireless signals transmitted by each wireless access point on each channel at the control device during the detection period (e.g., corresponding to the predetermined time interval) ; obtaining the channel quality indicator value for each channel based on the number of wireless access points on each channel in the corresponding detection period and the signal strength of the wireless signal transmitted by each wireless access point on each channel at the control device; and determining the target channel from each channel based on the channel quality indication value of each channel, where the target channel may be the channel with the best channel quality among the channels.

During each detection period, a target channel may be obtained, and after obtaining the target channel in the corresponding period, the process of determining whether the working channel of the target wireless router is the same as the target channel may be performed. If the channels are the same, determine whether the time lapse between the current time and the last time the wireless signal corresponding to each channel was detected equals to the predetermined time interval or not; if so, the steps in the next cycle may be performed; if not, the channel switching instruction may be sent to the target wireless router, so that the target wireless router may switch the working channel to the target channel. Further, after the channel switching instruction has been sent to the target wireless router, determine whether the time lapse between the current time and the last time the wireless signal corresponding to each channel was detected equals to the predetermined time interval or not; if so, the steps in the next cycle may be performed.

The wireless router control method provided in the present embodiment may include: for each channel that the wireless router may connect to, the control device may obtain the channel quality of the corresponding channel based on the number of wireless access points on the corresponding channel and the wireless signal strength of each wireless access point, where the wireless signal strength may be the signal strength of the wireless signal transmitted by the wireless access point at the control device; the control device may determine the target channel from each channel based on the channel quality of each channel, where the target channel may be the channel with the best channel quality among the channels; if the working channel of the target wireless router is different from the target channel, the control device may send a channel switching instruction to the target wireless router, where the channel switching instruction may include an identifier of the target channel, and the channel switching instruction may be used to instruct the target wireless router to switch the working channel to the target channel; and the target wireless router may switch the current working channel to the target channel based on the identifier of the target channel. The wireless router control method provided in the present embodiment allows the wireless router to work on the channel with the best channel quality, thereby improving the communication quality of the wireless router.

Referring to FIG. 3, the control device may include: a channel quality acquisition module 31; a target channel determination module 32; and a transmission module 33. In particular, for each channel that the wireless router may connect to, the channel quality acquisition module 31 may be used to obtain the channel quality of the corresponding channel based on the number of wireless access points on the corresponding channel and the wireless signal strength of each wireless access point, where the wireless signal strength may be the signal strength of the wireless signal transmitted by the wireless access point at the control device. Further, the target channel determination module 32 may be used to determine the target channel from each channel based on the channel quality of each channel, where the target channel may be a channel with the best channel quality among the channels. Furthermore, if the working channel of the wireless router is different from the target channel, the transmission module 33 may be used to send a channel switching instruction to the wireless router, where the channel switching instruction may include an identifier of the target channel, and the channel switching instruction may be used to instruct the wireless router to switch the working channel to the target channel.

More specifically, the channel quality acquisition module 31 may be used to obtain a channel quality indicator value of the corresponding channel based on the sum of the wireless signal strengths of all the wireless access points on the corresponding channel and the number of the wireless access points, where the channel quality indicator value may be used to indicate the channel quality of the channel.
