Description

Technical Field

[0001] The present invention relates to the field of wireless communications, and in particular to a method and system for adjusting the signal coverage of a router. Background Art

[0002] A router is a device that connects the local area networks and wide area networks in the Internet. It will automatically select and set routes according to the channel conditions, and send signals in the best path and in a forward and backward order. The router is the hub of the Internet, used to connect multiple logically separated networks. The so-called logical network represents a separate network or a subnet. When data is transmitted from one subnet to another, it can be completed through the routing function of the router, that is, the wireless router can be regarded as a repeater, which forwards the broadband network signal connected to the wall of the home to the nearby wireless terminals through the antenna, such as laptops, wifi-enabled mobile phones, iPads, etc.

[0003] With the rapid development of wireless communication technology, wireless routers have been widely used in various occasions, such as homes, companies, shopping malls, etc. At present, every household has a demand for WIFI and wireless routers, and routers have become a necessity. However, existing wireless routers are generally equipped with omnidirectional antennas (i.e., 360-degree uniform radiation in the horizontal directional diagram, which is usually called non-directional, and a beam with a certain width in the vertical directional diagram) for comprehensive signal radiation. However, in general, wireless routers are placed in corners, so that the omnidirectionally radiated signals will be wasted within a certain angle range, and in some scenarios, users do not need wireless routers to radiate comprehensively, but only need the signal radiation range to cover a certain area. Although it is now possible to improve the signal strength of wireless routers by combining directional antennas and omnidirectional antennas, the omnidirectional antenna is still not eliminated, and in certain scenarios, the radiated signal energy at certain angles will still be wasted.

[0004] The patent with the publication number CN 104917537A discloses a wireless router signal transmitting device, which belongs to the field of wireless router signal transmitting devices. Its structure mainly consists of: 1 modified wireless router and signal transmitting tower; the signal transmitting tower consists of: 2 fixed directional antenna, 3 rotating directional antenna, 4 omnidirectional antenna, 6 telecommunication pole, 5 direction rotation control device, 7 feeder; its main feature is that 1 modified wireless router is connected with 2 fixed directional antenna, 3 rotating directional antenna, 4 omnidirectional antenna of the transmitting tower through 7 feeder, and then the direction of 3 rotating directional antenna is adjusted through the direction rotation control device, so as to finally achieve the effect of improving signal coverage, concentrating signal and enhancing signal stability. This method can concentrate signal and enhance signal stability to a certain extent by combining directional antenna and omnidirectional antenna, but it still cannot avoid the waste of radiation signal energy at certain angles. Summary of the invention

[0005] The purpose of the present invention is to address the defects of the prior art and provide a method and system for adjusting the signal coverage range of a router based on a wide-beam antenna, which can flexibly and actively adjust the radiation range according to actual conditions, reduce the waste of radiation signal energy, reduce the interference effect on other surrounding wireless signals, and increase the strength of the radiation signal.

[0049] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0050] With the development of Internet technology, more and more terminal devices need to be connected to the network. Wireless networks are becoming more and more popular due to their greater flexibility. The purpose of the present invention is to address the defects of the prior art and provide a method and system for adjusting the signal coverage of a router based on a wide-beam antenna. The method can flexibly and actively adjust the radiation range according to actual conditions, reduce the waste of radiation signal energy, reduce the interference to other surrounding wireless signals, and increase the strength of the radiation signal.

[0051] Embodiment 1

[0052] This embodiment provides a method for adjusting the signal coverage of a router, comprising the steps of:

[0053] S11. Establish a wireless connection with the terminal device;

[0054] S12. Determine the location information of the terminal device according to the signal strength fed back by the terminal device and adjust the beam direction of the wide-beam antenna according to the location information of the terminal device.

[0055] Optionally, the terminal device is a smart device with wireless connection function, such as a mobile phone, a laptop computer, an iPad, etc.

[0056] The method for adjusting the signal coverage of a router in this embodiment is performed by a wireless router.

[0057] It should be noted that the antenna used with the wireless router in this embodiment is a wide-beam omnidirectional antenna that can rotate freely 360°.

[0058] Specifically, in the initial state, the wireless router is in omnidirectional radiation mode. After the terminal device scans the signal of the wireless router, it establishes a connection with the wireless router. Then the wireless router determines the location information of the terminal device based on the signal strength fed back by the terminal device. The wireless router adjusts the beam pointing of the wide-beam antenna according to the location information (that is, adjusts the signal coverage range of the wireless router).

[0059] Furthermore, the specific steps of determining the location information of the terminal device according to the signal strength fed back by the terminal device and adjusting the beam pointing of the wide beam antenna according to the location information of the terminal device are:

[0060] A1. Polling to detect the difference in signal strength between each pair of wide beam antennas pointing to opposite directions from the terminal device;

[0061] A2. Determine the wide beam antenna pair with the largest signal strength difference;

[0062] A3. Direct the beam of the wide-beam antenna with the largest signal strength difference that feedbacks the terminal device signal to the location of the terminal device.

[0063] Specifically, the original beams of the omnidirectional antennas in the wireless router of this embodiment are arranged in sequence, and the total radiation area is composed of an omnidirectional antenna combination, a control switch, and a power divider. The antenna combination in this embodiment is mainly composed of 2n antenna units with a certain beam width, such as Figure 2 As shown, it is a schematic diagram of the wide beam antenna unit of the wireless router of the present invention. Assuming that the beam coverage range of each antenna is Ap, the original coverage can reach 360° coverage.

[0064] like Figure 2 As shown, Ap and An+p have opposite coverage ranges, such as Figure 3 FIG. 1 is a schematic diagram of a switch combination of a wide beam antenna unit of a wireless router according to the present invention.

[0065] like Figure 3 As shown in the figure, the pair of antennas Ap and An+p with opposite coverage are controlled by a set of switch arrays. The 0 part indicates that there is a power divider here. When SW1 is connected to 0, the other two 0 ends can only be allocated half of the total input power. There is no power divider in the 1 part. When SW1 is connected to 1, the power of the 1 end is the full input power.

[0066] The switch status of SW1 / SW2 / SW3 is controlled by the chip. (SW1, SW2, SW3) represents the switch status of the corresponding switch at this time. For example, (0, 0, 0) means that each switch is connected to the 0 terminal.

[0067] First, the wireless router polls and detects the difference in signal strength fed back by the terminal device between each pair of wide beam antennas with opposite beam directions. The specific process is: first detect the signal strength fed back by the terminal device of the first antenna directly opposite to it. For example, the switch state of centimeter switch A1, An+1 is set to (0, 0, 1). At this time, A1 performs signal coverage, and the signal strength fed back by the user is RSSI (A1); then the switch state is changed to (0, 1, 0). At this time, An+1 performs signal coverage, and the signal strength fed back by the user is RSSI (An+1); then the difference between RSSI (A1) and RSSI (An+1) is calculated. Similarly, the difference in signal strength between each pair of antennas is polled and detected.

[0068] After obtaining the signal strength difference between each pair of antennas, the pair of wide-beam antennas with the largest difference pointing opposite to each other can be determined. Among this pair of wide-beam antennas pointing opposite to each other, the area covered by the wide-beam antenna signal with a high signal strength received from the terminal device is the area closest to the terminal device (i.e., the location of the terminal device). The beam of the wide-beam antenna is then directed to this area, and the wide-beam antenna with a high signal strength received from the terminal device is disconnected. In this way, the wide-beam antenna equipped with the wireless router can automatically adjust the beam direction so that it is concentrated in the user's activity range (i.e., the area described by the terminal device), and the non-user's activity area is not covered by the beam of the wide-beam antenna. For example: confirm that the signal difference between the wide-beam antenna and the terminal device feedback of Ap, An+p is the largest, and the signal strength fed back by the wide-beam antenna Ap to the terminal device is large, then the location of the terminal device exists in the coverage range of Ap, and the switch combination of Ap, An+p is adjusted to (1, 1, 0), that is, An+p is no longer connected to the radiation range, that is, An+p is no longer connected to the radiation range, only Ap is connected to the input, and the radiation energy of Ap is no longer half of the input power, but the full input power.

[0069] Furthermore, if the signal strength of the terminal device is less than a preset signal strength threshold, the beams of multiple wide beam antennas are directed to the location of the terminal device, thereby enhancing the signal strength of the location of the terminal device and ensuring the user's network experience.

[0070] Accordingly, this embodiment also provides a system for adjusting the signal coverage of a router, such as Figure 4 As shown, including:

[0071] A connection module 11 is used to establish a wireless connection with a terminal device;

[0072] The adjustment module 12 is used to determine the location information of the terminal device according to the signal strength fed back by the terminal device and adjust the beam pointing direction of the wide beam antenna according to the location information of the terminal device.

[0073] Furthermore, the specific steps of determining the location information of the terminal device according to the signal strength fed back by the terminal device and adjusting the beam pointing of the wide beam antenna according to the location information of the terminal device are:

[0074] A1. Polling to detect the difference in signal strength between each pair of wide beam antennas pointing to opposite directions from the terminal device;

[0075] A2. Determine the wide beam antenna pair with the largest signal strength difference;

[0076] A3. Direct the beam of the wide-beam antenna with the largest signal strength difference that feedbacks the terminal device signal to the location of the terminal device.

[0077] Furthermore, if the signal strength of the terminal device is less than a preset signal strength threshold, the beams of multiple wide-beam antennas are directed toward the location of the terminal device.

[0078] This embodiment determines the location information of the terminal device through the signal strength fed back by the terminal device and adjusts the beam pointing of the wide-beam antenna according to the location information of the terminal, so as to flexibly and actively adjust the radiation range of the wireless router according to actual conditions, reduce the waste of radiation signal energy, reduce mutual interference with other wireless signals, and ensure the user's network experience.

[0079] Embodiment 2

[0080] This embodiment provides a method for adjusting the signal coverage of a router. Figure 5 Said, comprising the steps of:

[0081] S21. Establish a wireless connection with the terminal device;

[0082] S22. Determine the location information of the terminal device according to the signal strength fed back by the terminal device and adjust the beam direction of the wide-beam antenna according to the location information of the terminal device.

[0083] S23. Record the position combination of the beam pointing of the wide beam antenna after each adjustment;

[0084] S24. Determine whether the frequency of occurrence of the position combination reaches the preset frequency and whether the duration reaches the preset duration. If so, jump to step S25.

[0085] S25. Setting the position combination as a common combination.

[0086] Optionally, the terminal device is a smart device with wireless connection function, such as a mobile phone, a laptop computer, an iPad, etc.

[0087] The method for adjusting the signal coverage of a router in this embodiment is performed by a wireless router.

[0088] It should be noted that the antenna used with the wireless router in this embodiment is a wide-beam omnidirectional antenna that can rotate freely 360°.

[0089] Specifically, in the initial state, the wireless router is in omnidirectional radiation mode. After the terminal device scans the signal of the wireless router, it establishes a connection with the wireless router. Then the wireless router determines the location information of the terminal device based on the signal strength fed back by the terminal device. The wireless router adjusts the beam pointing of the wide-beam antenna according to the location information (that is, adjusts the signal coverage range of the wireless router).

[0090] Furthermore, the specific steps of determining the location information of the terminal device according to the signal strength fed back by the terminal device and adjusting the beam pointing of the wide beam antenna according to the location information of the terminal device are:

[0091] A1. Polling to detect the difference in signal strength between each pair of wide beam antennas pointing to opposite directions from the terminal device;

[0092] A2. Determine the wide beam antenna pair with the largest signal strength difference;

[0093] A3. Direct the beam of the wide-beam antenna with the largest signal strength difference that feedbacks the terminal device signal to the location of the terminal device.

[0094] Specifically, the original beams of the omnidirectional antennas in the wireless router of this embodiment are arranged in sequence, and the total radiation area is composed of an omnidirectional antenna combination, a control switch, and a power divider. The antenna combination in this embodiment is mainly composed of 2n antenna units with a certain beam width, such as Figure 2 As shown, it is a schematic diagram of the wide beam antenna unit of the wireless router of the present invention. Assuming that the beam coverage range of each antenna is Ap, the original coverage can reach 360° coverage.

[0095] like Figure 2 As shown, Ap and An+p have opposite coverage ranges, such as Figure 3 FIG. 1 is a schematic diagram of a switch combination of a wide beam antenna unit of a wireless router according to the present invention.

[0096] like Figure 3As shown in the figure, the pair of antennas Ap and An+p with opposite coverage are controlled by a set of switch arrays. The 0 part indicates that there is a power divider here. When SW1 is connected to 0, the other two 0 ends can only be allocated half of the total input power. There is no power divider in the 1 part. When SW1 is connected to 1, the power of the 1 end is the full input power.

[0097] The switch status of SW1 / SW2 / SW3 is controlled by the chip. (SW1, SW2, SW3) represents the switch status of the corresponding switch at this time. For example, (0, 0, 0) means that each switch is connected to the 0 terminal.

[0098] First, the wireless router polls and detects the difference in signal strength fed back by the terminal device between each pair of wide beam antennas with opposite beam directions. The specific process is: first detect the signal strength fed back by the terminal device of the first antenna directly opposite to it. For example, the switch state of centimeter switch A1, An+1 is set to (0, 0, 1). At this time, A1 performs signal coverage, and the signal strength fed back by the user is RSSI (A1); then the switch state is changed to (0, 1, 0). At this time, An+1 performs signal coverage, and the signal strength fed back by the user is RSSI (An+1); then the difference between RSSI (A1) and RSSI (An+1) is calculated. Similarly, the difference in signal strength between each pair of antennas is polled and detected.

[0099] After obtaining the signal strength difference between each pair of antennas, the pair of wide-beam antennas with the largest difference pointing opposite to each other can be determined. Among this pair of wide-beam antennas pointing opposite to each other, the area covered by the wide-beam antenna signal with a high signal strength received from the terminal device is the area closest to the terminal device (i.e., the location of the terminal device). The beam of the wide-beam antenna is then directed to this area, and the wide-beam antenna with a high signal strength received from the terminal device is disconnected. In this way, the wide-beam antenna equipped with the wireless router can automatically adjust the beam direction so that it is concentrated in the user's activity range (i.e., the area described by the terminal device), and the non-user's activity area is not covered by the beam of the wide-beam antenna. For example: confirm that the signal difference between the wide-beam antenna and the terminal device feedback of Ap, An+p is the largest, and the signal strength fed back by the wide-beam antenna Ap to the terminal device is large, then the location of the terminal device exists in the coverage range of Ap, and the switch combination of Ap, An+p is adjusted to (1, 1, 0), that is, An+p is no longer connected to the radiation range, that is, An+p is no longer connected to the radiation range, only Ap is connected to the input, and the radiation energy of Ap is no longer half of the input power, but the full input power.

[0100] This embodiment determines the location information of the terminal device based on the signal strength fed back by the terminal device and adjusts the beam pointing of the wide-beam antenna based on the location information of the terminal. It also records the position combination of the beam pointing of the wide-beam antenna after each adjustment, that is, records the position of the beam pointing of all wide-beam antennas in the wireless router, and then determines whether the frequency of occurrence of the position combination reaches the preset frequency and whether the duration reaches the preset duration. If the frequency of occurrence and the duration of the position combination reach the preset threshold (that is, the position combination of the wide-beam antenna beam pointing is the area with more user activities), the position combination is set as a commonly used combination.

[0101] Furthermore, the method further comprises the steps of:

[0102] Determine whether the current time period is a time period with less user activity;

[0103] If yes, then checking whether the position combination of the beam pointing of the wide beam antenna is a default combination;

[0104] If not, the position combination of the beam pointing of the wide beam antenna is adjusted to a default combination.

[0105] Specifically, the wireless router will automatically switch the working mode. During time periods with more user activities, such as during the day, the wireless router will automatically switch the position combination of the wide-beam antenna's beam pointing to a commonly used combination mode. If the current time period is during a time period with less user activity, such as at night, the wireless router will adjust the position combination of the wide-beam antenna's beam pointing to the default combination.

[0106] Accordingly, this embodiment also provides a system for adjusting the signal coverage of a router, such as Figure 6 As shown, including:

[0107] A connection module 21, used to establish a wireless connection with a terminal device;

[0108] The adjustment module 22 is used to determine the location information of the terminal device according to the signal strength fed back by the terminal device and adjust the beam pointing direction of the wide beam antenna according to the location information of the terminal device.

[0110] The first judgment module 24 is used to judge whether the frequency of occurrence of the position combination reaches a preset frequency and whether the duration reaches a preset duration;

[0111] The setting module 25 is used to set the position combination as a common combination when the frequency of occurrence and the duration of the position combination reach preset values.

[0112] Furthermore, the specific steps of determining the location information of the terminal device according to the signal strength fed back by the terminal device and adjusting the beam pointing of the wide beam antenna according to the location information of the terminal device are:

[0113] A1. Polling to detect the difference in signal strength between each pair of wide beam antennas pointing to opposite directions from the terminal device;

[0114] A2. Determine the wide beam antenna pair with the largest signal strength difference;

[0115] A3. Direct the beam of the wide-beam antenna with the largest signal strength difference that feedbacks the terminal device signal to the location of the terminal device.

[0116] Furthermore, if the signal strength of the terminal device is less than a preset signal strength threshold, the beams of multiple wide-beam antennas are directed toward the location of the terminal device.

[0117] Furthermore, it also includes:

[0118] The second judgment module is used to judge whether the current time period is a time period with less user activities;

[0119] A detection module, used to detect whether the position combination of the beam pointing of the wide beam antenna is a default combination when the current time period is a time period with less user activity;

[0120] The adjustment module is used to adjust the position combination of the beam pointing of the wide beam antenna to the default combination when the current time period is a time period with less user activity and the position combination of the beam pointing of the wide beam antenna is not the default combination.

[0121] This embodiment determines the location information of the terminal device through the signal strength fed back by the terminal device and adjusts the beam pointing of the wide-beam antenna according to the location information of the terminal, so as to flexibly and actively adjust the radiation range of the wireless router according to actual conditions, reduce the waste of radiation signal energy, reduce mutual interference with other wireless signals, ensure the user's network experience, and improve the user experience.
