Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for controlling a coverage area of a wireless network.

Background

With the development of internet technology, networks have become an essential part of people's life. Many public places such as hotels, coffee houses, restaurants and exhibition halls, or private places such as families, are provided with wireless networks, which brings convenience for users to enjoy services provided by the wireless networks. Generally, an access control device (such as a wireless router) is placed in each of these places, an antenna is disposed in the access control device, and the access control device with the antenna has a wireless network coverage function, and can transmit a wireless network signal through the antenna, so that all access devices (such as smart phones) entering the wireless network coverage area can access the wireless network.

However, in practice, it has been found that sometimes a network administrator does not want all access devices entering such locations to access the wireless network, such as: in a home wireless network, a user does not want the room in which his or her children are located to cover the home wireless network, such as: in a public wireless network, a user may wish to overlay the public wireless network only in the area where the VIP user is located. Since these wireless networks already define the coverage area of the antenna for transmitting signals when installed, users cannot control certain specific areas within the coverage area, and thus cannot limit access devices in these specific areas to access the wireless network.

and controlling the motor to rotate towards the target direction by the target angle so as to drive the antenna to be controlled to rotate by the rotation angle of the antenna to be adjusted.

The antenna to be controlled is driven to rotate through the motor, the radiation direction of the antenna to be controlled can be controlled, and therefore the coverage area of the wireless network can be controlled in an individualized mode.

With reference to the first aspect of the embodiment of the present invention, in a fourth possible implementation manner of the first aspect of the embodiment of the present invention, the antenna to be controlled is a phased array antenna, and after the height of the access control device from a horizontal plane is obtained, the method further includes:

In a second aspect of the embodiments of the present invention, an apparatus for controlling a coverage area of a wireless network is disclosed, that is, a coverage area control apparatus of a wireless network is applied to an access control device, where the access control device includes an antenna to be controlled, and the coverage area control apparatus of the wireless network includes a functional unit configured to perform some or all of the steps of any of the methods in the first aspect of the embodiments of the present invention.

The third aspect of the embodiments of the present invention discloses a device for controlling a coverage area of a wireless network, that is, a coverage area control device of a wireless network, which is applied to an access control device, where the access control device includes an antenna to be controlled, and the coverage area control device of the wireless network includes: the apparatus may comprise a processor, an input device, and a memory configured to store instructions, the processor being configured to execute the instructions, the processor executing the instructions to perform some or all of the steps of any of the methods of the first aspect of the embodiments of the present invention.

In some possible implementations, the height of the access control device from the horizontal plane may be obtained by means of user input, or may be detected and obtained by a built-in sensor for measuring the height.

In some possible implementation manners, when the antenna to be controlled is driven to rotate by the motor, if the current output power of the antenna to be controlled cannot meet the requirement of the output power required by the coverage distance of the wireless network input by the user, the output power of the antenna to be controlled needs to be adjusted in a power control manner, that is, the motor control and the power control are combined, so that the personalized control of the coverage area of the wireless network is better realized.

In the embodiment of the invention, a coverage area control device of a wireless network is applied to access control equipment, the access control equipment comprises an antenna to be controlled, the coverage area control device of the wireless network receives the coverage distance of the wireless network input by a user and acquires the height of the access control equipment from a horizontal plane; furthermore, the coverage area control device of the wireless network determines the radiation radius required by the antenna to be controlled according to the coverage distance and the height, and inquires the target antenna output power corresponding to the radiation radius required by the antenna to be controlled from the preset corresponding relation between the radiation radius and the antenna output power, so that the coverage area control device of the wireless network can adjust the output power of the antenna to be controlled to the target antenna output power.

On one hand, in the process of controlling the coverage area of the wireless network, the coverage area controlling device of the wireless network may determine the target antenna output power that needs to be adjusted by the antenna to be controlled according to the coverage distance of the wireless network and the height of the access control device from the horizontal plane, which are input by the user. Because the coverage area of the wireless network is related to the output power of the antenna, controlling the output power is equivalent to controlling the coverage area of the wireless network, the coverage distances of the wireless network input by users are different, and the corresponding target antenna output powers required to be adjusted by the antenna to be controlled are different, so that the coverage areas of the wireless network to be controlled are different, and therefore, the individualized control of the coverage area of the wireless network can be realized through a power control mode;

on the other hand, in the process of controlling the coverage area of the wireless network, the output power of the target antenna to be adjusted is generally smaller than the current output power to be controlled (i.e., the maximum output power of the antenna when leaving the factory), so that the power consumption of the access control device can be reduced to a certain extent.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first," "second," "third," and "fourth," etc. in the description and claims of the invention and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The embodiment of the invention discloses a method and a device for controlling a coverage area of a wireless network, which can realize personalized control on the coverage area of the wireless network and reduce power consumption. The following are detailed below.

In order to better understand the coverage area control method and apparatus of the wireless network disclosed in the embodiments of the present invention, a network architecture suitable for the embodiments of the present invention is described below. Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture according to an embodiment of the present invention. As shown in fig. 1, the system architecture is composed of an access control device and a plurality of access devices, wherein the access control device is used for controlling the coverage area of a wireless network, the access control device may be a routing device, and the routing device may include a wireless router, a wired router, and any device capable of connecting to each local area network and wide area network in the internet, and automatically selecting and setting a route according to the channel condition, and sending signals in a front-back order with an optimal path, and the like. The access control device comprises an antenna, wherein the antenna can be any one of an omnidirectional antenna, a directional antenna and a phased array antenna.

The antenna in the access control equipment has a wireless network coverage function, and can transmit wireless network signals through the antenna, so that all access equipment entering the wireless network coverage area can be accessed to the wireless network. Usually, the maximum output power of an antenna is already specified by the antenna at the time of factory shipment, i.e., the maximum coverage area of the antenna is limited. As shown in fig. 1, the area included by the oval boundary line is the maximum coverage area of the antenna, all access devices (e.g., access device a, access device B, and access device C) in the maximum coverage area can access the wireless network, and an access device (e.g., access device D) outside the maximum coverage area cannot access the wireless network. The access Device may include, but is not limited to, various user devices such as a smart phone, a notebook Computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), and a smart wearable Device (e.g., a smart watch and a smart band).

It should be noted that the antenna in the access control device in fig. 1 is configured to perform omni-directional radiation by default at the maximum output power of the antenna, so that all the access devices in the maximum coverage area can access the wireless network. Fig. 2b, fig. 3b, and fig. 4b, which are disclosed later in the present invention, are schematic diagrams of coverage area examples that are presented after the coverage area control method of a wireless network disclosed in the embodiment of the present invention is adopted on the basis of the network architecture shown in fig. 1 and on the basis of the network architecture shown in fig. 1.

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for controlling a coverage area of a wireless network according to an embodiment of the present invention, where the method is applied to an access control device. As shown in fig. 2, the method may include the steps of:

201. a coverage area control device of a wireless network receives an input coverage distance of the wireless network.

In the embodiment of the invention, the coverage area control device of the wireless network is applied to the access control equipment. The access control device is used for controlling a coverage area of a wireless network, and includes an antenna, where the antenna may be any one of an omni-directional antenna, a directional antenna, and a phased array antenna.

Generally, there are two main factors affecting the coverage area of the antenna radiation signal: the output power of the antenna and the radiation direction of the antenna. Generally, an antenna has a maximum output power specified by the antenna at the time of factory shipment, that is, the maximum coverage area of the antenna is limited. To enable individualized control of the coverage area of the wireless network, a user may do so by at least one of changing the output power of the antenna and changing the radiation direction of the antenna.

In the embodiment of the present invention, when a user needs to control a coverage area of a wireless network, the user may input a coverage distance of the wireless network in a coverage area control device of the wireless network, for example: 5 meters, 10 meters, etc. Wherein the coverage distance is generally for a distance in a horizontal plane.

As an optional implementation manner, after the coverage area control device of the wireless network receives the coverage distance of the wireless network, the following steps can be further executed:

and judging whether the coverage distance is an effective distance, if so, executing 202, and if not, ending the process.

In this alternative embodiment, the effective distance is the maximum coverage distance specified when the antenna is shipped from the factory.

It should be noted that the current coverage distance of the antenna in the access control device is a default distance, that is, a maximum coverage distance corresponding to a maximum coverage area specified when the antenna is shipped from a factory.

202. A coverage area control device of a wireless network acquires the height of an access control device from a horizontal plane.

In the embodiment of the present invention, the coverage area control device of the wireless network may obtain the height of the access control device from the horizontal plane in a manner of user input, or the coverage area control device of the wireless network may detect and obtain the height of the access control device from the horizontal plane by using a built-in sensor for measuring the height. The height of the access control device from the horizontal plane may be understood as the height of the antenna plus the height of the support. It should be noted that, in practical applications, the coverage area control device of the wireless network generally needs to make a certain range of revisions on the height of the access control device from the horizontal plane.

203. And the coverage area control device of the wireless network determines the radiation radius required by the antenna to be controlled according to the coverage distance and the height.

In the embodiment of the invention, if the antenna in the access control equipment is an omnidirectional antenna, the antenna to be controlled is the omnidirectional antenna; if the antenna in the access control device is a directional antenna group, the antenna to be controlled can be at least one directional antenna in the directional antenna group, wherein the at least one directional antenna is an open directional antenna; if the antenna in the access control device is a phased array antenna, the antenna to be controlled is a phased array antenna.

In the embodiment of the present invention, the coverage area control device of the wireless network may determine a radiation radius required by the antenna to be controlled according to the coverage distance and the height, where the radiation radius is a distance from a circle center to an edge of an effective coverage area of the wireless network, the circle center is a center point of the antenna to be controlled, and the effective coverage area of the wireless network is a coverage area matched with the coverage distance.

Referring to fig. 2a, fig. 2a is a schematic diagram illustrating a relationship between a radiation radius and a corner of an antenna according to an embodiment of the present invention. As shown in fig. 2a, h is the height of the access control device from the horizontal plane, d is the coverage distance of the wireless network, and r is the radiation radius required by the antenna to be controlled, as can be seen from fig. 2a, h and d constitute two right-angle sides of a right-angled triangle, and r constitutes the hypotenuse of the right-angled triangle.

204. A coverage area control device of a wireless network inquires target antenna output power corresponding to the radiation radius required by an antenna to be controlled from the corresponding relation between the preset radiation radius and the antenna output power.

In the embodiment of the present invention, the correspondence between the radiation radius and the antenna output power may be obtained through a plurality of experiments performed in advance by a user, where the radiation radius and the antenna output power in the correspondence are in a one-to-one correspondence.

After the coverage area control device of the wireless network determines the radiation radius required by the antenna to be controlled, the coverage area control device of the wireless network can query the target antenna output power corresponding to the radiation radius required by the antenna to be controlled from the preset corresponding relationship between the radiation radius and the antenna output power. The target antenna output power is usually smaller than the default maximum output power of the antenna to be controlled when the antenna leaves the factory.

205. The coverage area control device of the wireless network adjusts the output power of the antenna to be controlled to the output power of the target antenna.

In the embodiment of the present invention, the output power of the antenna to be controlled is usually the default maximum output power when the antenna to be controlled leaves the factory, and when the output power of the antenna to be controlled needs to be changed through power control, the coverage area control device of the wireless network may adjust the output power of the antenna to be controlled to the target antenna output power. Obviously, the output power of the target antenna is smaller than the maximum output power, and the adjusted output power of the antenna to be controlled is reduced, so that the coverage area of the wireless network signal transmitted by the antenna to be controlled is smaller than the maximum coverage area of the antenna to be controlled when the antenna to be controlled leaves the factory. Therefore, only access devices entering the coverage area of the wireless network signal transmitted by the antenna to be controlled can access the wireless network.

Referring to fig. 2b, fig. 2b is a schematic diagram of an example of an antenna coverage area according to an embodiment of the present invention, where an antenna of the access control device shown in fig. 2b performs omnidirectional radiation. As shown in fig. 2b, the maximum coverage area of the antenna in the access control device is the area encompassed by the maximum circle in fig. 2b, wherein, the access device A, the access device B and the access device C are all positioned in the maximum coverage area, and the access device D is located outside the maximum coverage area, as can be seen from fig. 2b, the coverage area of the wireless network signal transmitted by the antenna to be controlled in the access control device is the effective coverage area in fig. 2b, i.e., the smaller circle shown in fig. 2B, where both access device a and access device B are located within the effective coverage area, and both access device C and access device D are outside the effective coverage area, only access device a and access device B within the effective coverage area can access the wireless network, and neither access device C nor access device D located outside the effective coverage area can access the wireless network.

It should be noted that the antenna in fig. 2b may be an omnidirectional antenna, a directional antenna group for omnidirectional coverage, or a phased array antenna for omnidirectional coverage.

It can be seen that implementing the method shown in fig. 2 can implement personalized control over the coverage area of the wireless network, and in addition, since the output power required by the effective coverage area is less than the maximum output power required by the maximum coverage area, the power consumption of the access control device can also be reduced.

In the method flow described in fig. 2, the coverage area control device of the wireless network is applied to the access control device, the access control device includes an antenna to be controlled, and the coverage area control device of the wireless network can receive the coverage distance of the wireless network and obtain the height of the access control device from the horizontal plane; further, the radiation radius required by the antenna to be controlled is determined according to the coverage distance and the height, and the target antenna output power corresponding to the radiation radius required by the antenna to be controlled is inquired from the preset corresponding relation between the radiation radius and the antenna output power, so that the coverage area control device of the wireless network can adjust the output power of the antenna to be controlled to the target antenna output power.

on the other hand, in the process of controlling the coverage area of the wireless network, the output power of the target antenna to be adjusted is generally smaller than the maximum output power of the antenna to be controlled when the antenna is shipped from a factory, so that the power consumption of the access control device can be reduced to a certain extent.

Referring to fig. 3, fig. 3 is a schematic flow chart illustrating another method for controlling a coverage area of a wireless network according to an embodiment of the present invention, where the method is applied to an access control device, and the access control device includes an antenna to be controlled. As shown in fig. 3, the method may include the steps of:

301. a coverage area control device of a wireless network receives an opening instruction input to at least one directional antenna in a directional antenna group included in an access control device.

In the embodiment of the present invention, the access control device includes a directional antenna group, and the directional antenna group implements 360 ° omni-directional coverage, for example: 3 directional antennas of 120 °, 4 directional antennas of 90 °, etc. The user can select which directional antennas in the directional antenna group to turn on as required, such as: in the 4 directional antennas of 90 °, a user can flexibly select one directional antenna, two directional antennas, three directional antennas, or four directional antennas. Wherein, only the opened directional antenna can transmit wireless network signals, and the unopened directional antenna does not work.

302. A coverage area control device of a wireless network turns on at least one directional antenna as an antenna to be controlled.

303. A coverage area control device of a wireless network receives an input coverage distance of the wireless network.

In this embodiment of the present invention, if the number of at least one directional antenna turned on by the user is greater than 1, the user may input, for each directional antenna, the coverage distance of the wireless network corresponding to the directional antenna, where the coverage distance of the wireless network corresponding to each directional antenna is different, for example: the coverage distance of the wireless network corresponding to the directional antenna 1 is d1, the coverage distance of the wireless network corresponding to the directional antenna 2 is d2, and the coverage distance of the wireless network corresponding to the directional antenna 3 is d3, wherein d1, d2 and d3 are all different; alternatively, the user may input the coverage distance of the same wireless network for all directional antennas that are turned on, such as: the coverage distance of the wireless network input for directional antenna 1 and directional antenna 2 that are turned on is d 4.

304. A coverage area control device of a wireless network acquires the height of an access control device from a horizontal plane.

305. And the coverage area control device of the wireless network determines the angular displacement of the antenna to be adjusted of the antenna to be controlled according to the coverage distance and the height.

In the embodiment of the present invention, the angular displacement of the antenna to be adjusted may include a rotation angle of the antenna to be adjusted and a rotation direction of the antenna to be adjusted. Generally, according to the magnitude relationship between the coverage distance of the wireless network and the current coverage distance of the wireless network, it can be determined in which direction the antenna to be controlled should be rotated.

Referring to fig. 3a, fig. 3a is a schematic diagram illustrating a rotation angle and a corner relationship of a directional antenna according to an embodiment of the present invention. As shown in fig. 3a, if the current coverage distance of the directional antenna is d, and the height of the access control device from the horizontal plane is h, the current angle of the directional antenna may be calculated as β according to the pythagorean theorem of the right triangle and the corner relationship, if the coverage distance of the wireless network input by the user is the target coverage distance d1, the angle of the directional antenna at d1 may be correspondingly calculated as β 1, the rotation angle of the antenna to be adjusted required by the directional antenna may be determined as α 1 according to β and β 1, and at the same time, the rotation direction of the antenna to be adjusted required by the directional antenna may be determined as rotating to the lower left, and similarly, if the coverage distance of the wireless network input by the user is the target coverage distance d2, the angle of the directional antenna at d2 may be correspondingly calculated as β 2, and the rotation angle of the antenna to be adjusted as α 2 according to β and β 2, meanwhile, the rotation direction of the antenna to be adjusted, which is required by the directional antenna, can be determined to be the rotation to the upper right.

306. The coverage area control device of the wireless network judges whether the rotation angle of the antenna to be adjusted exceeds a preset maximum rotation angle, if so, 307-309 is executed, and if not, 310-311 is executed.

In the embodiment of the present invention, the maximum rotation angle of the antenna is generally specified when the antenna is shipped, for example, 15 °. When the coverage area control device of the wireless network determines the rotation angle of the antenna to be adjusted of the antenna to be controlled, the coverage area control device of the wireless network can firstly judge whether the rotation angle of the antenna to be adjusted exceeds a preset maximum rotation angle, if so, the coverage area control device of the wireless network can only control the coverage area of the wireless network in a power control mode, but cannot control the radiation direction of the antenna to be controlled, and if not, the coverage area control device of the wireless network can control the antenna to be controlled to rotate so as to realize the control of the radiation direction.

402. A coverage area control device of a wireless network acquires the height of an access control device from a horizontal plane.

403. A coverage area control device of the wireless network receives an input offset angle of a coverage area of the phased array antenna.

In the embodiment of the invention, the offset angle is mainly used for controlling the coverage area of the phased array antenna. Generally, the default angle of the offset angle is 0 ° or 360 °, that is, omnidirectional radiation is performed, and when the offset angle is not the default angle, the coverage area control device of the wireless network may perform control of the coverage area of the phased array antenna according to the offset angle.

Referring to fig. 4a, fig. 4a is a schematic diagram illustrating an offset angle and a corner relationship of a phased array antenna according to an embodiment of the present invention. As shown in fig. 4a, the offset angle is an included angle between the first straight line and the second straight line in the clockwise direction, the point a is an orthographic projection area center point of the access control device, the central axis of the access control device passes through the point a, the point B is a mark angle 0 point of the access control device, a first plane can be determined by the point B and the central axis of the access control device, a perpendicular line is made from the point B to the central axis of the access control device in the first plane, the first straight line can be determined, a second straight line can be determined according to the offset angle input by the user and the first straight line, and the second straight line is an orthographic projection area arc bisector of the antenna radiation area. As can be seen from fig. 4a, the orthographic projection area of the antenna radiation area is the area encompassed by the arc in fig. 4 a. The coverage area control device of the wireless network can determine the coverage area of the wireless network desired by the user according to the orthographic projection area of the antenna radiation area.

404. The coverage area control device of the wireless network judges whether the offset angle is a preset minimum offset angle or a preset maximum offset angle, if so, 405-407 is executed, and if not, 408-411 is executed.

In an embodiment of the present invention, the preset minimum offset angle may be 0 °, and the preset maximum offset angle is 360 °. When the coverage area control device of the wireless network judges that the offset angle is the preset minimum offset angle or the preset maximum offset angle, the coverage area control device of the wireless network can determine that the omnidirectional radiation is required at the moment, and the control of the coverage area of the wireless network is realized by adopting a power control mode; when the coverage area control device of the wireless network judges that the offset angle is not the preset minimum offset angle or the preset maximum offset angle, a phase control (namely phase control) mode is needed to change the direction of the maximum value of an antenna directional pattern so as to achieve the purpose of controlling the beam forming coverage area.

405. And the coverage area control device of the wireless network determines the radiation radius required by the phased array antenna according to the coverage distance and the height.

406. A coverage area control device of a wireless network inquires target antenna output power corresponding to the radiation radius required by an antenna to be controlled from the corresponding relation between the preset radiation radius and the antenna output power.

407. The coverage area control device of the wireless network adjusts the output power of the antenna to be controlled to the output power of the target antenna and ends the process.

408. And the coverage area control device of the wireless network determines a target phase shift value and a target amplitude required by the phased array antenna according to the coverage distance, the offset angle and the height.

In the embodiment of the invention, the phased array antenna is composed of a first array antenna and a second array antenna which are perpendicular to each other, the first array antenna and the second array antenna are respectively composed of a plurality of antenna radiation units and a plurality of phase shifters, and each radiation unit is controlled through amplitude and phase shift. The phase shifter used by the access control equipment is a continuous phase shifter, and the phase shift value of the continuous phase shifter can be continuously changed within the range of 0-360 degrees. Generally, the array antennas in a phased array antenna are at an angle (0 °, 180 °) to each other, and when the angle is 90 °, interference when the first and second array antennas perpendicular to each other transmit signals is minimized.

In the embodiment of the invention, when the coverage area control device of the wireless network judges that the offset angle is not the preset minimum offset angle or the preset maximum offset angle, the coverage area control device of the wireless network can substitute the coverage distance, the offset angle and the height into a relevant theoretical formula according to the relevant theoretical formula, and the target phase shift value and the target amplitude required by the phased array antenna can be calculated through conversion. The following relationships exist: f (d, h, θ) → (r, { (a11, β 11) (a12, β 12) · (A1n, β 1n) }, { (a21, β 21) (a22, β 22) · (A2m, β 2m) }), wherein d is a coverage distance, h is a height, θ is an offset angle, r is a radiation radius, a is an amplitude, and β is a phase shift value, and specifically, (a11, β 11) (a12, β 12) · (A1n, β 1n) is a target amplitude and a target phase shift value required for the antenna of the first array, (a21, β 21) (a22, β 22. (A2m, β 2m) is a target amplitude and a target phase shift value required for the antenna of the second array. The related theoretical formula may include, but is not limited to, an electromagnetic field equation, a superposition theorem, an antenna pattern, a multiplication theorem, an euler formula, and the like.

409. A coverage area control device of a wireless network adjusts a current phase shift value of a phase shifter included in a phased array antenna to a target phase shift value.

In the embodiment of the invention, the coverage area control device of the wireless network adjusts the current phase shift value of the phase shifter included in the phased array antenna to the target phase shift value, so that the phase control of the phased array antenna is realized, and the purpose of controlling the beam forming coverage area can be achieved. Generally, the phase control is generally controlled by a processor, and the phase change speed is high, namely the maximum pointing direction of an antenna pattern or other parameters change rapidly.

Further, assuming that the polarization factor of the phased array antenna is α, controlling the beamformed coverage area may be achieved by the following logic:

a1 (1j α + β 1) and a2 (1j α + β 2)

Where a1 represents the amplitude of all sub-array antennas of the first array antenna, β 1 represents the phase shift value of all sub-array antennas of the first array antenna, a2 represents the amplitude of all sub-array antennas of the second array antenna, and β 2 represents the phase shift value of all sub-array antennas of the second array antenna.

410. The coverage area control device of the wireless network inquires the antenna output power corresponding to the target amplitude from the preset corresponding relation between the amplitude and the antenna output power.

In the embodiment of the present invention, when the coverage area control device of the wireless network determines that the offset angle is not the preset minimum offset angle or the preset maximum offset angle, the coverage area control device of the wireless network needs to perform power control on the output power of the phased array antenna in addition to performing phase control on the phased array antenna. The output power of the phased array antenna is related to the amplitude of the phased array antenna, and a user can obtain the corresponding relation between the amplitude of the phased array antenna and the output power of the phased array antenna through a plurality of experiments in advance, wherein the amplitude in the corresponding relation and the output power of the phased array antenna are in one-to-one corresponding relation.

411. A coverage area control device of a wireless network adjusts the output power of a phased array antenna to the inquired antenna output power.

Referring to fig. 4b, fig. 4b is a schematic diagram of an example coverage area of a phased array antenna according to an embodiment of the present invention. As shown in fig. 4b, the maximum coverage area of the phased array antenna in the access control device is the area encompassed by the maximum circle in fig. 4b, wherein, the access device A, the access device B and the access device C are all positioned in the maximum coverage area, while the access device D is located outside this maximum coverage area, it can also be seen from fig. 4b that the coverage area of the wireless network signals transmitted by the phased array antenna in the access control device is the effective coverage area in fig. 4b, i.e., the smaller ellipse shown in fig. 4B, where access device B, access device C and access device D are all located outside the effective coverage area, and only the access device a is located within the effective coverage area, only the access device a located within the effective coverage area can access the wireless network, and none of the access device B, the access device C, and the access device D located outside the effective coverage area can access the wireless network.

It can be seen that implementing the method shown in fig. 4 can implement personalized control over the coverage area of the wireless network, and in addition, since the output power required by the effective coverage area is less than the maximum output power required by the maximum coverage area, the power consumption of the access control device can also be reduced.
