[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] In wireless communication systems, signal attenuation and insufficient signal coverage have long been a problem that has plagued the industry. A single antenna layout and feeder line often make it difficult to achieve uniform and effective signal coverage in complex and changing indoor and outdoor environments. For example, in places such as large shopping malls and high-rise office buildings, signal blind spots or areas with weak signal coverage often appear due to the obstruction of building structures and the complexity of signal propagation paths. In addition, the impedance mismatch between the feeder and the antenna will further aggravate signal attenuation, affecting communication quality and user experience.

[0043] In one embodiment, see Figure 1 The present application provides an antenna matching optimization method, which may include the following steps: S10 to S40.

[0044] Step S10: Divide the area to be covered into multiple sub-areas.

[0045] As an example, the area to be covered can be divided according to the actual situation of the area to be covered, and the number of the divided sub-areas can also be set according to actual needs. In this embodiment, the area of ​​each sub-area should be controlled within a certain range, for example, the area of ​​each sub-area can be controlled within about 100 square meters.

[0046] As an example, the area to be covered may be divided into several grids, each grid being one of the sub-areas.

[0047] In one example, taking a shopping mall as an example, each floor of the shopping mall can be divided into several sub-areas with an area of ​​100 square meters. For example, if the area of ​​each floor of the shopping mall is 2000 square meters, each floor of the shopping mall can be divided into 20 sub-areas.

[0048] By dividing the area to be covered as described above, the uniformity of antenna arrangement can be ensured, each sub-area can be effectively covered, and the signal coverage in each sub-area can be ensured to be uniform and efficient.

[0049] As an example, after step S10, the following step may also be included: based on the building structure characteristics, environmental characteristics and coverage requirements in each of the sub-areas, the type of antenna to be set in each of the sub-areas is selected.

[0050] As an example, the appropriate antenna type for each sub-area can be selected based on the building structure characteristics, environmental characteristics and coverage requirements in each sub-area. Omnidirectional antennas can be used for uniform coverage of a large area, and directional antennas can be used for enhanced coverage in a specific direction; if the sub-area is an open area, an omnidirectional antenna can be selected, and if the sub-area includes corridors and corners, a directional antenna can be selected.

[0051] Step S20: installing an antenna in each of the sub-areas.

[0052] As an example, step S20 may include the following steps: S201 - S202 .

[0053] S201: Disposing an antenna at the center of each of the sub-areas.

[0054] S202: Setting the height of the antenna in each of the sub-areas based on the building structure characteristics, environmental characteristics and crowd distribution density in each of the sub-areas.

[0055] As an example, initially, the antennas may be arranged prior to the center positions of the sub-areas to ensure uniform spacing between the antennas and avoid signal overlap or blind spots.

[0056] As an example, the height of the antenna can be finely adjusted according to the building structure characteristics, environmental characteristics and crowd distribution density in each of the sub-areas; generally, the antenna can be installed at a height of 2 to 5 meters from the ground.

[0057] For example, if a sub-area is located in a high-rise building, the height of the antenna in the sub-area should be appropriately increased to avoid being blocked between floors. If the sub-area is an open area, the height of the antenna in the sub-area can be appropriately lowered; if the sub-area is in a complex environment, such as a multi-obstacle area, the height of the antenna in the area can be appropriately increased to ensure effective signal propagation.

[0058] Specifically, taking a shopping mall as an example, the height of the antenna can be adjusted according to the building structure of the shopping mall in the sub-area, such as the distribution of columns, partition structures, etc. In an open area, the height of the antenna can be set to 2 meters, and in an area with many obstacles, the height of the antenna can be increased to 4 to 5 meters.

[0059] By adjusting the height of the antenna in the sub-area in combination with the density of the flow of people in the sub-area (ie, the distribution of users in the sub-area), the antenna signal can better cover the user-dense area.

[0060] As an example, after step S202, the following steps may also be included: S203 to S204.

[0061] S203: Perform signal testing on each of the sub-areas.

[0062] S204: Adjust the position and height of the antenna in each of the sub-areas based on the test result of the signal test.

[0063] As an example, in step S203, professional testing equipment may be used to perform a signal test on each of the sub-areas, and the signal test may include but is not limited to a signal strength test, a signal coverage test, a signal stability test, and the like.

[0064] As an example, in step S204, the position and height of the antenna in the sub-area can be fine-tuned according to the test results in step S203 to ensure that the antenna in the sub-area can achieve the best coverage effect for the sub-area. Specifically, after the antenna is set at the center of the sub-area, if the test results show that the signal strength and signal coverage of part of the sub-area are weak, for example, the signal strength and signal coverage of the right area of ​​the antenna in the sub-area are weak, the antenna in the sub-area can be moved to the right side of the center of the sub-area; if the test results show that the signal strength and signal coverage of the edge area of ​​the sub-area are weak, the height of the antenna in the sub-area can be adjusted to increase.

[0065] As an example, after step S204, the position and height of the antenna in each sub-area may be confirmed, and the antenna in each sub-area may be installed and set according to the determined position and height.

[0066] Through the above steps, efficient antenna layout can be achieved under various environmental conditions, which can significantly improve signal coverage and user experience.

[0067] Step S30: connecting each of the antennas to a main signal source via a power divider.

[0068] As an example, each of the antennas and the power divider, and the power divider and the main signal source, can be connected via a single-mode optical fiber. Single-mode optical fiber has the characteristics of low loss and high bandwidth, and can effectively transmit signals to ensure signal quality.

[0069] As an example, the length of the single-mode optical fiber connecting each of the antennas should be controlled to be as short as possible to avoid signal attenuation caused by the single-mode optical fiber being too long. In order to ensure that the length of the single-mode optical fiber is as short as possible, the single-mode optical fiber should be laid in a straight line as much as possible to reduce bending or winding. The single-mode optical fiber can be connected to the antenna, the power divider and the main signal source by optical fiber fusion splicing technology to ensure the stability and low loss of the single-mode optical fiber connection point.

[0070] As an example, an optical signal converter may be installed at the connection between the single-mode optical fiber and the antenna. The function of the optical signal converter is to convert the optical signal transmitted by the single-mode optical fiber into an electrical signal so that the antenna can receive and transmit. Specifically, the selection of the optical signal converter needs to consider the conversion efficiency and working stability, and it needs to ensure that the signal does not suffer significant loss during the conversion process.

[0071] As an example, the power distributor is used to evenly distribute the power of the main signal source to each of the antennas, and the selection of the power distributor can be reasonably configured according to the number of antennas and the power required by each of the antennas. During the power distribution process, the power distributor needs to ensure that the power obtained by each antenna is consistent to avoid uneven signal coverage caused by uneven power of each antenna.

[0072] After the power divider is set up, a power monitoring device may be installed at each antenna to monitor the power status of each antenna in real time; and according to the monitoring result, the power divider may be dynamically adjusted to ensure the power balance of each antenna.

[0073] In one embodiment, the main signal source is placed in the center of the shopping mall and connected to the antennas on each floor using the single-mode optical fiber. An efficient optical signal converter is installed at the connection between each antenna and the single-mode optical fiber to ensure that the efficiency of converting optical signals into electrical signals reaches more than 95%; for example, an optical signal converter with a signal of XYZ can be selected, and its conversion efficiency is 98%. A 1-to-10 power divider can be used to evenly distribute the power of the main signal source to multiple (for example, 10) antennas; taking the distribution to 10 antennas as an example, if the power of the main signal source is 100W, the power allocated to each antenna is 10W. When laying out the single-mode optical fiber, try to choose a straight path to reduce bending; use optical fiber fusion technology to ensure that the loss of the single-mode optical fiber connection point is less than 0.1dB. A power monitoring device is installed at each antenna to monitor the power of each antenna in real time, and dynamically adjust the power divider according to the monitoring results to ensure that the power of each antenna is consistent.

[0074] Through the above steps, efficient and uniform signal source distribution can be achieved in complex scenarios (such as large shopping malls), significantly improving signal coverage and user experience.

[0075] Step S40: adjusting the direction of the antenna in each of the sub-areas based on the building structure characteristics, environmental characteristics and crowd distribution density of each of the sub-areas.

[0076] As an example, in order to ensure that each antenna can cover its sub-area to the maximum extent and effectively avoid signal interference and blind spots, the direction of the antenna in each sub-area can be adjusted in the following manner: record the building structure (i.e., building structure characteristics), obstacle distribution (i.e., environmental characteristics) and crowd distribution density around the antenna in each sub-area; use professional signal testing equipment to conduct a comprehensive test of the signal strength and coverage of each sub-area and obtain detailed test data; adjust the horizontal and vertical directions of each antenna according to the building structure characteristics, environmental characteristics, crowd distribution density and test data. The horizontal adjustment mainly considers the distribution of buildings and obstacles around the antenna to ensure that the signal can bypass the buildings and obstacles and cover more users; the vertical adjustment mainly considers the height of the building and the distribution of users to ensure that the signal is evenly covered at different heights.

[0077] Specifically, according to the building structure characteristics, environmental characteristics, crowd distribution density and test data, the specific method for adjusting the horizontal and vertical directions of each antenna can be: if there are buildings and obstacles around the antenna, the horizontal direction of the antenna can be adjusted in combination with the test data, so that the horizontal direction of the antenna is offset to one side of the building and obstacle (the side test data shows that the signal strength and coverage are weaker), so that the signal of the antenna can bypass the building and obstacle. If the building and obstacle are relatively large, and the horizontal direction of the antenna cannot bypass the building and obstacle, the vertical direction of the antenna can be adjusted to increase the radiation height of the antenna signal, so that the signal of the antenna can pass over the building and obstacle. In addition, if uniform signal coverage is required for areas at different heights of the building, the vertical direction of the antenna can be adjusted so that the signal of the antenna can reach the required height area (this area can be the area where the test data shows that the signal strength and coverage are weak) to ensure that the antenna signal has uniform coverage at different heights. For crowd density, if there is an area with a large crowd density in the sub-area where the antenna is located, and the test data shows that the signal strength or signal coverage in the area with a large crowd density is weak, the horizontal direction of the antenna can be adjusted toward the area with a large crowd density; if the area with a large crowd density is located in a building floor higher than the antenna, the vertical direction of the antenna can be adjusted according to the height of the area with a large crowd density to ensure that the antenna signal can enhance the coverage of the area with a large crowd density; it is necessary that the horizontal and vertical directions of the antenna can be adjusted at the same time.

[0078] It should be noted that the horizontal direction of the antenna mainly refers to the radiation direction of the antenna; the vertical direction of the antenna mainly refers to the radiation height of the antenna.

[0079] As an example, see Figure 2After step S40, the following steps may also be included: S50 to S60.

[0080] S50: Perform signal testing on each of the sub-areas.

[0081] S60: Based on the test result of the signal test, adjust the angle of the antenna in each of the sub-areas.

[0082] As an example, professional tools (such as a signal coverage monitoring device and real-time data analysis software) may be used to perform real-time monitoring of the adjusted antenna direction (ie, perform signal testing on each of the sub-areas).

[0083] As an example, based on the result of the signal test, the angle of the antenna is fine-tuned to ensure that the signal coverage and signal strength are optimal. During the fine-tuning process, at least one of the uniformity of signal coverage, the stability of signal strength, and the user experience, etc., needs to be considered.

[0084] As an example, the angle of the antenna refers to the angle between the antenna and the north direction and the angle between the antenna and the horizontal direction, respectively; wherein, the angle between the antenna and the north direction is the azimuth angle, and the angle between the antenna and the horizontal direction is the downtilt angle; in the process of adjusting the angle of the antenna in each of the sub-areas, at least one of the azimuth angle and the downtilt angle of the antenna can be adjusted.

[0085] As an example, in the process of fine-tuning the angle of the antenna based on the result of the signal test, if the result of the signal test shows that there is a weak coverage area or a blind coverage area with weak signal strength in the sub-area where the antenna is located, the angle of the antenna can be fine-tuned (for example, fine-tuning at least one of the azimuth angle and downtilt angle) so that the antenna signal can enhance the coverage of the weak coverage area or the blind coverage area.

[0086] As an example, after step S60, it may also include repeating step S50 and step S60 at least once; specifically, the number of times step S50 and step S60 need to be repeated may be selected according to actual needs. Through multiple repetitions, multiple rounds of optimization may be achieved to gradually refine the antenna direction. Through the above multiple rounds of optimization, the coverage effect and signal quality of the antenna may be significantly improved.

[0087] As an example, the uniformity of signal coverage can be obtained by the following formula:

[0088]

[0089] Among them, S i is the signal strength of the i-th test point; is the average signal strength of all test points; n is the total number of test points. The "uniformity index" in the formula is the uniformity index of signal strength. The smaller the value of the uniformity index, the more uniform the signal coverage. Through the above monitoring and fine-tuning, the uniformity index can be made as small as possible to achieve the best signal coverage effect.

[0090] In one example, a signal testing device is used to collect signal strength S at each test point. i ; Calculate the average signal strength S of all test points based on the signal strength of all test points; Calculate the uniformity index using the above formula; Fine-tune the antenna angle based on the uniformity index; Re-collect data and recalculate the uniformity index until the uniformity index reaches the preset threshold.

[0091] Through the above data processing logic, the adjustment effect of the antenna can be scientifically evaluated and optimized to ensure the uniformity and stability of signal coverage.

[0092] In one implementation, taking a high-rise office building as an example, the floor structure, office area distribution, and obstacle conditions of each floor can be recorded. Use signal testing equipment to test the signal strength at each location on each floor and record the test data. According to the floor structure, office area distribution, obstacle conditions, and test data of each floor, adjust the horizontal direction of the antenna to avoid obstacles such as pillars and walls. Adjust the vertical direction of the antenna to ensure that the signal can cover office areas at different heights. Based on the signal coverage monitoring system, monitor the signal coverage of the antenna after adjustment in real time. According to the monitored data, fine-tune the angle of the antenna to ensure uniform signal coverage and no blind spots. Perform multiple rounds of adjustment and monitoring, and re-perform signal testing and data analysis after each adjustment; for example, after the first round of adjustment, if it is found that the signal strength of a sub-area is insufficient, fine-tune the angle of the antenna in the sub-area, and then test again until the optimal coverage effect is achieved.

[0093] Through the above steps, fine antenna direction adjustment can be achieved in complex environments such as high-rise office buildings, which can significantly improve signal coverage and user experience.

[0094] As an example, each of the antennas is also connected to a feeder, that is, each of the antennas is connected to a feeder. In order to ensure impedance matching between the feeder and the antenna, reduce signal reflection and loss, and improve overall signal transmission efficiency, after the antenna is set in each of the sub-areas, the following steps may also be included: measuring the impedance value between the connected antenna and the feeder; selecting an impedance matcher based on the impedance value, and connecting the impedance matcher to the connection between the antenna and the feeder.

[0095] As an example, a high-precision network analyzer can be used to measure the actual impedance values ​​of the feeder and antenna respectively. The network analyzer can provide accurate impedance parameters, including resistance and reactance components; record the impedance values ​​of each feeder and antenna measured by the high-precision network analyzer to provide a data basis for subsequent impedance matching.

[0096] As an example, you can select a suitable impedance matcher based on the impedance values ​​of the connected feeder and antenna; the role of the impedance matcher is to compensate for the impedance difference between the feeder and antenna and reduce signal reflection. When installing the impedance matcher, make sure that it is firmly connected and has good contact to avoid signal loss due to connection problems.

[0097] As an example, when planning the path of the feeder, it is necessary to plan the optimal path of the feeder in combination with the actual layout of each sub-area; the optimal path should be as short and straight as possible, with fewer bends and windings to reduce signal loss. In the process of planning the path of the feeder, it is necessary to consider the obstacles and potential interference sources that the feeder passes through, and try to avoid obstacles and potential interference sources.

[0098] As an example, the length of the feeder can be accurately calculated based on the planned feeder path. The actual laying of the feeder needs to be considered to ensure the accuracy of the feeder length. In order to cope with possible path adjustments and future expansion needs, a 10% feeder length margin needs to be reserved, that is, the actual feeder length should be 10% longer than the planned feeder length.

[0099] In one embodiment, a network analyzer with a signal of XYZ can be used to measure the impedance values ​​of the feeder and the antenna, respectively. For example, the measured feeder impedance can be 50Ω, and the antenna impedance can be 75Ω. At this time, an impedance matcher suitable for impedance conversion from 50Ω to 75Ω can be selected and installed at the connection between the feeder and the antenna to ensure that the impedance matcher is firmly connected and not loose. In combination with the layout of the shopping mall, the optimal path of the feeder is planned, and a straight path is selected as much as possible to reduce bends; for example, the path from the main signal source to the antenna is planned as a straight line, avoiding elevator shafts and large equipment. According to the planned path, the length of the feeder is calculated to be 200 meters, and a 10% margin is reserved, that is, the feeder length is designed to be 220 meters; a feeder with a length of 220 meters is used for laying.

[0100] As an example, after setting the feeder, the following steps may also be included: performing a signal test on each of the sub-areas; and adjusting the path of each feeder based on the test result of the signal test in this step.

[0101] As an example, professional testing equipment may be used to perform signal testing on each of the sub-areas. The signal testing may include but is not limited to signal strength testing, signal coverage testing, signal stability testing, and the like.

[0102] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0103] Based on the same inventive concept, the embodiment of the present application also provides an antenna matching optimization system for implementing the antenna matching optimization method involved above. The implementation scheme for solving the problem provided by the antenna matching optimization system is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more antenna matching optimization system embodiments provided below can refer to the limitations of the antenna matching optimization method above, and will not be repeated here.

[0104] In another embodiment, see Figure 3 The present application also provides an antenna matching optimization system, which may include: a division module (not shown), multiple antennas 10, a main signal source 11, a power divider 12 and a first adjustment module 14; wherein the division module is used to divide the area to be covered into multiple sub-areas; multiple antennas 10 are arranged in each of the sub-areas; the power divider 12 is connected to the main signal source 11 and each of the antennas 10; the first adjustment module 14 is used to adjust the direction of the antenna 10 in each of the sub-areas based on the architectural structure characteristics, environmental characteristics and pedestrian distribution density of each of the sub-areas.

[0105] In the above-mentioned antenna matching optimization system, the power of the main signal source 11 is reasonably distributed to each of the antennas 10 through the power divider 12, and the direction of the antenna 10 in each of the sub-areas is adjusted according to the architectural structure characteristics, environmental characteristics and crowd distribution density of each of the sub-areas. It can adapt to complex indoor and outdoor environments, avoid the occurrence of signal blind spots or areas with weak signal coverage, solve the problem of insufficient signal coverage, improve signal coverage effects, improve communication quality and user experience, and has broad application prospects and important practical value.

[0106] As an example, the number of the antennas 10 may be the same as the number of the sub-areas, and the antennas 10 may be arranged in a one-to-one correspondence with the sub-areas. Figure 3 For ease of display, only one antenna 10 is shown.

[0107] As an example, the type of the antenna 10 in each sub-area can be selected based on the building structure characteristics, environmental characteristics and coverage requirements of each sub-area. Omnidirectional antennas can be suitable for uniform coverage of a large area, and directional antennas can be suitable for enhanced coverage in a specific direction; if the sub-area is an open area, an omnidirectional antenna can be selected, and if the sub-area includes corridors and corners, etc., a directional antenna can be selected.

[0108] As an example, in general, the antenna can be installed at a height of 2 to 5 meters above the ground. If the sub-area is located in a high-rise building, the height of the antenna in the sub-area should be appropriately increased to avoid obstruction between floors. If the sub-area is an open area, the antenna in the sub-area can be appropriately lowered; if the sub-area is in a complex environment, for example, a multi-obstacle area, the antenna in the area can be appropriately raised to ensure effective signal propagation.

[0109] As an example, the power distributor 12 is used to evenly distribute the power of the main signal source 11 to each of the antennas 10, and the selection of the power distributor 12 can be reasonably configured according to the number of the antennas 10 and the power required by each of the antennas 10. During the power distribution process, the power distributor 12 needs to ensure that the power obtained by each of the antennas 10 is consistent to avoid uneven signal coverage caused by uneven power of each of the antennas 10.

[0110] After setting up the power divider 12, a power monitoring device (not shown) can also be installed at each antenna 10 to monitor the power status of each antenna 10 in real time; and based on the monitoring results, the power divider 12 is dynamically adjusted to ensure power balance of each antenna 10.

[0111] As an example, the antenna matching optimization system may further include a single-mode optical fiber 13, each of the antennas may be connected to the power divider 12 via the single-mode optical fiber 13, and the power divider 12 may be connected to the main signal source 11 via the single-mode optical fiber 13. The single-mode optical fiber 13 has the characteristics of low loss and high bandwidth, and can effectively transmit signals to ensure signal quality.

[0112] As an example, the length of the single-mode optical fiber 13 connecting each of the antennas 10 should be controlled to be as short as possible to avoid signal attenuation caused by the single-mode optical fiber 13 being too long. In order to ensure that the length of the single-mode optical fiber 13 is as short as possible, the single-mode optical fiber 13 should be laid in a straight line as much as possible to reduce bending or winding. The single-mode optical fiber 13 can be connected to the antenna 10, the power divider 12 and the main signal source 11 by optical fiber fusion splicing technology to ensure the stability and low loss of the connection point of the single-mode optical fiber 13.

[0113] As an example, an optical signal converter (not shown) may also be installed at the connection between the single-mode optical fiber 13 and the antenna 10. The function of the optical signal converter is to convert the optical signal transmitted by the single-mode optical fiber 13 into an electrical signal so that the antenna 10 can receive and transmit. Specifically, the selection of the optical signal converter needs to consider the conversion efficiency and working stability, and it needs to ensure that the signal does not suffer significant loss during the conversion process.

[0114] As an example, the antenna matching optimization system may also include: a testing device 15; the testing device 15 is used to perform signal testing on each of the sub-areas; the first adjustment module 14 is also used to adjust the angle of the antenna 10 in each of the sub-areas based on the test results of the signal test.

[0115] As an example, the testing device 15 may include a signal coverage monitoring device and real-time data analysis software; the testing device 15 may test the uniformity of signal coverage of each sub-area, the stability of signal strength, etc.

[0116] The angle of the antenna refers to the angle between the antenna and the north direction and the angle between the antenna and the horizontal direction respectively; wherein, the angle between the antenna and the north direction is the azimuth angle, and the angle between the antenna and the horizontal direction is the downtilt angle; in the process of adjusting the angle of the antenna in each of the sub-areas, at least one of the azimuth angle and the downtilt angle of the antenna can be adjusted.

[0117] As an example, in addition to testing the signal coverage of each sub-area, the testing device 15 can also be used to test the signal strength and signal stability of each sub-area.

[0118] As an example, the antenna matching optimization system may further include: a second adjustment module 16, wherein the second adjustment module 16 is configured to adjust the position and height of the antenna 10 in each of the sub-areas based on the test result of the signal test.

[0119] As an example, the second adjustment module 16 may adjust the position and height of the antenna 10 when the antenna 10 is arranged in each sub-area.

[0120] As an example, the antenna matching optimization system may further include a feeder line (not shown), and each of the antennas 10 is connected to a different feeder line.

[0121] As an example, the antenna matching optimization system may also include an impedance matcher (not shown), which is connected to the connection between the antenna 10 and the feeder. The impedance matcher can ensure impedance matching between the feeder and the antenna, reduce signal reflection and loss, and improve the overall signal transmission efficiency. It should be noted that the impedance matcher is selected based on the impedance value of the connected antenna 10 and the feeder, and the impedance matcher can compensate for the impedance difference between the connected antenna 10 and the feeder. When installing the impedance matcher, ensure that it is firmly connected and in good contact to avoid signal loss due to connection problems.

[0122] As an example, when planning the path of the feeder, it is necessary to plan the optimal path of the feeder in combination with the actual layout of each sub-area; the optimal path should be as short and straight as possible, with fewer bends and windings to reduce signal loss. In the process of planning the path of the feeder, it is necessary to consider the obstacles and potential interference sources that the feeder passes through, and try to avoid obstacles and potential interference sources.

[0123] As an example, the length of the feeder can be accurately calculated based on the planned feeder path. The actual laying of the feeder needs to be considered to ensure the accuracy of the feeder length. In order to cope with possible path adjustments and future expansion needs, a 10% feeder length margin needs to be reserved, that is, the actual feeder length should be 10% longer than the planned feeder length.

[0124] Each module in the above antenna matching optimization system can be implemented in whole or in part by software, hardware, or a combination thereof. Each module can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute operations corresponding to each module.

[0125] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0126] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
