These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation
[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments made by those skilled in the art under the guidance of these embodiments are within the scope of protection of this application.
[0047] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0048] First, let me explain the terms used in this application:
[0049] Resource Block (RB) Reservation: In 5G systems, the basic scheduling unit for data channel resource allocation in the frequency domain is the RB, or resource block. RB resource reservation allows multiple slices to share the RB resources of the same cell.
[0050] Digital indoor distribution system (IDS) source: Indoor coverage of mobile broadband data. Through digital technologies in indoor coverage, digital transmission via fiber optic cables, twisted-pair cables, etc., reaches the terminal digital source, achieving active and controllable coverage. Leveraging the advantages of high bandwidth and ease of maintenance of digital transmission, it enables flexible networking and significantly improved performance for 5G terminal coverage. The advantages of digital IDS lie in significantly reducing the construction and maintenance costs of ordinary passive indoor coverage facilities, promoting continuous improvement in the mobile broadband experience.
[0051] Distributed Antenna System Locations: A Distributed Antenna System (DAS) is a successful solution for improving the mobile communication environment within buildings, targeting indoor user groups. It utilizes passive components such as feeders, couplers, and combiners to distribute the mobile communication base station signal evenly throughout the building, ensuring ideal signal coverage. Distributed antenna system locations are the installation positions of radio frequency antennas at the end of a traditional passive distributed system, used to cover a fixed area. These are typically omnidirectional fixed-point antennas or directional fixed-point panel antennas.
[0052] Macro base station source: A macro base station is part of the access network. It is a radio frequency (RF) device or antenna that converts baseband signals into RF signals and amplifies them to cover a wide area. It is mainly used to discover 5G RF signals and provide service to users in the corresponding area. Macro base station sources are high-performance, high-reliability 5G RF processing equipment and 5G RF antennas used at the end of the 5G network to cover large outdoor spaces. They mainly include active antenna units (AAUs) and radio remote units (RRUs).
[0053] In existing technologies, traditional or digital indoor distributed antenna systems (DAS) are used to implement wireless network coverage. Typical indoor DAS systems are implemented based on objective performance evaluations such as wireless network coverage requirements, edge field strength, and user perceived speed. Ordinary users and industry users share the wireless coverage network, competing for network resources. To address these issues, this application proposes a solution that satisfies both the high-density, heavy-load needs of ordinary users and effectively addresses the specialized, customized support services required by industry users, thereby achieving reliable and stable 5G network service guarantees across all scenarios in large stadiums.
[0054] The technical solution of this application will now be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0055] Figure 1 This is a schematic diagram of a network coverage quality processing system provided in this application, applied in a large stadium. Figure 1 As shown, the network coverage quality processing system 10 includes: a digital indoor distribution system source 11 or a DAS indoor distribution system point 12 located on the roof of the large stadium or at the top of the stands; a digital indoor distribution system source 11 located at the edge of the large stadium; a macro base station source 13 located at the front edge of the high-rise stands of the large stadium; and control equipment 14.
[0056] More specifically, control device 14 is used to obtain the network coverage requirements of a large stadium.
[0057] The control device 14 is also used to control the digital indoor distribution system signal source, the traditional indoor distribution system and / or the macro station signal source to perform corresponding network coverage processing according to the network coverage requirements of the large stadium.
[0058] Large stadiums typically consist of three tiers of stands, specifically, such as Figure 2 The grandstand scene diagram provided in this application shows that the large stadium includes a first-floor grandstand, a second-floor grandstand, and a third-floor grandstand, with the following structure: Figure 3The schematic diagram of the grandstand scene provided in this application shows that the grandstand's cross-section is a right-angled triangle. The base of the first-floor grandstand is 26.07 meters long, 15 meters high, and the hypotenuse is 30.08 meters long. The antenna is mounted at a height of 10.3 meters. The antenna reaches one end of the hypotenuse at 8 meters, the other end at 29 meters, and the midpoint of the hypotenuse at 16 meters. The angle between the antenna and the vertical normal to the ground is 89.9°. The base of the second-floor grandstand is 19.2 meters long, 16 meters high, and the hypotenuse is 25 meters long. The antenna is mounted at a height of 24 meters. The antenna is 0.4 meters long, 7 meters to one end of the hypotenuse, 24 meters to the other end, and 14 meters to the midpoint of the hypotenuse. The angle between the antenna and the vertical normal to the ground is 73.7°. The three-tiered grandstand is 34 meters long at the base, 13 meters high, and 36.4 meters long at the hypotenuse. The antenna is mounted at a height of 53.2 meters. The antenna is 10 meters to one end of the hypotenuse, 35 meters to the other end, and 21 meters to the midpoint of the hypotenuse. The angle between the antenna and the vertical normal to the ground is 89°. Figure 3 This is merely a typical or general scene in a large stadium. Figure 3 The median value is merely an illustrative example; this application does not necessarily reflect the intended meaning. Figure 3 The specific values are not specifically limited.
[0059] 5G network coverage in the grandstand area will be achieved using on-site facilities. Specifically, digital distributed antenna system (DAS) sources or DAS points will be installed on building rooftops and grandstand tops. In indoor venues such as the National Stadium, rooftop installation is recommended. Wireless network coverage in this area will be implemented strictly according to standard wireless network design requirements, effectively ensuring coverage and user experience. Wireless network coverage will be achieved using Distributed Massive MIMO (DMM) technology, ensuring capacity, reducing interference, and achieving a scale of 3000 seats per cell. Grandstand coverage will utilize maximum frequency resources, achieving 2-3 carrier frequency resource coverage. While ensuring capacity, this will effectively provide wireless resources for the full-scenario implementation of 2B and Business-to-Consumer (2C) business isolation.
[0060] Specifically, the installation of digital indoor distribution system (DAS) sources, DAS indoor distribution system locations, and macro base station sources within the sports stadium is as follows: Figure 4The large sports stadium competition area scene diagram provided in this application shows that the locations marked 1 and 2 in the diagram are the perimeter of the field. Digital indoor distributed antenna system (DAS) sources are installed at these perimeter locations to provide network coverage to the center of the field. The effective coverage distance of the digital DAS sources is approximately 60 meters. Coverage is provided sequentially along the perimeter, with one DAS source installed every 15 to 20 meters depending on the site conditions. There are at least two sources on each side, and at least eight sources are installed on all four sides. Specifically, two sources can effectively address the impact of obstruction, improve wireless network coverage, and achieve full-band coverage of the digital DAS. Alternatively, macro base station sources can also be installed at the perimeter, generally with at least two devices / frequency bands, installed symmetrically.
[0061] The locations marked with 3 in the diagram are ceiling locations. Due to their higher ceiling height, ceiling locations are suitable for installing macro base station equipment. Specifically, if the ceiling height in the stadium is greater than 30 meters, it is recommended to use macro base station equipment to cover the center of the arena. If the ceiling height is less than or equal to 30 meters, digital indoor distributed antenna systems (DAS) can be used to achieve network coverage in the center. When using digital DAS equipment to achieve network coverage in the center, use full-band or multi-band equipment. Depending on the actual space size and coverage requirements, the number of signal source points should be no less than two. When using macro base station equipment, it is recommended to use no less than two devices / frequency bands to achieve supplementary coverage and mutually ensure coverage of blind spots.
[0062] The location marked by 5 in the figure is the front edge of the high-rise grandstand. This location can be regarded as a backup location for the field edge and roof. Digital indoor distribution equipment cannot be installed at the front edge of the high-rise grandstand. For coverage and capacity supplementation at the field center location, macro base station signal sources such as millimeter wave equipment can be installed to achieve inter-frequency networking and improve capacity. It is recommended that there be no less than 2 millimeter wave devices / frequency bands at this location.
[0063] The location marked with 4 in the diagram is the site center enclosure. Equipment installation at this location depends on requirements and site conditions. If the floor or surface materials at the site center suffer significant wear (>30dB), no equipment should be installed there. If wear is manageable, dense networking can be implemented; however, this option is uncontrollable or has many limitations and is recommended as a secondary reference. If implementation is necessary, macro base stations and digital indoor distribution systems can be used for dense networking. If macro base stations and digital indoor distribution system signal sources are installed at the site center enclosure, it is recommended to use at least two devices / frequency bands. The digital indoor distribution system signal source or macro base station antenna at the enclosure will transmit radio frequency signals upwards, penetrating the floor coverage facilities to achieve bottom-up network coverage.
[0064] Specifically, the installation location, height, and related information of the digital indoor distribution system signal source, DAS indoor distribution system location, and macro station signal source are shown in Table 1.
[0065] Table 1 Installation Location and Related Information
[0066]
[0067]
[0068] The above installation locations can effectively achieve 5G coverage within the arena without affecting the stage design or the aesthetics of the venue. Furthermore, due to the different installation locations, there are different requirements for the installation process and hanging height at each location. Specifically, point 1 should be installed at a low height, with sturdy and compact mounting hardware. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion. Point 2 should also be installed at a low height, with sturdy and compact mounting hardware. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion, but the antenna itself should not be too large. Point 3 should be installed at a high position, as close as possible to the front edge of the ceiling. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion, requiring a relatively large tilt adjustment angle. Point 4 should be installed at a moderate position, with precise calculations required for the distance from the floor and the placement of the antenna. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion, and the equipment should be installed horizontally or facing the floor. For millimeter-wave antennas installed at point 5, they should be installed as close as possible to the front edge of the ceiling. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion, with a certain tilt adjustment angle, and the mounting hardware should be compact and aesthetically pleasing.
[0069] It applies the concept of distributed coverage networking using digital indoor distribution or traditional indoor distribution, and also involves the application of macro base stations in large sports stadium coverage scenarios. It not only meets the coverage and capacity requirements of high-density networking in large sports stadiums, but also enables continuous coverage in large spaces such as stadium stands and arenas, realizing multi-device networking and meeting the network needs of the media industry.
[0070] In various usable spaces such as stadium stands, building rooftops, arena perimeters, arena storage areas, and the front edge of stands, a wide range of multi-point coverage technologies are applied to meet the needs of different devices, locations, and requirements, as well as multiple backup 5G network solutions. This enables multi-dimensional application networking in large stadiums, achieving high, medium, and low-level three-dimensional coverage, and building a high-capacity, high-sensitivity, and multi-dimensional dense 5G network in relatively narrow spaces.
[0071] In this embodiment, by using digital distributed antenna system (DAS) sources or DAS points located on the roof and at the top of the stands of a large stadium, digital DAS sources positioned at the edge of the stadium, millimeter-wave equipment positioned at the front edge of the upper stands, and control equipment, the system controls the digital DAS sources, DAS points, and / or macro base station sources to perform corresponding network coverage processing according to the network coverage requirements of the stadium. Compared to existing technologies that use traditional or digital DAS systems for wireless network coverage, this embodiment implements typical network coverage processing based on objective performance evaluations such as wireless network coverage requirements, edge field strength, and user perceived speed. Indoor distributed antenna system (DAS) wireless network coverage is shared by both general users and industry users, leading to competition for network resources. This application addresses this by installing digital indoor DAS signal sources, DAS indoor DAS locations, macro base station signal sources, and control equipment within a large stadium. Based on the network coverage requirements of the large stadium, the application controls the digital indoor DAS signal sources, DAS indoor DAS locations, and / or macro base station signal sources, comprehensively utilizing multiple systems, frequency bands, and devices to improve 5G network coverage quality and effectively reduce 5G network interference. This not only meets the high-density, heavy-load needs of general users but also effectively addresses the specialized, customized support services required by industry users, achieving reliable and stable 5G network service guarantees across all scenarios in large stadiums.
[0072] This application provides a network coverage quality processing system for use in large stadiums, comprising: digital indoor distributed system (DAS) signal sources or DAS indoor distributed system points located on the roof or at the top of the stands of the large stadium; digital indoor distributed system signal sources located at the edge of the stadium; macro base station signal sources located at the front edge of the upper stands of the large stadium; and control equipment.
[0073] The control equipment is specifically used to: when the network coverage requirement is determined to be a single-band network, use slicing technology to isolate 2B2C service slices.
[0074] Specifically, when only single-band networking capability is available across the entire scenario, digital indoor distribution coverage is implemented throughout the entire scenario, employing slicing technology to ensure industry needs are met. For example... Figure 5 This diagram illustrates the network coverage of a large sports stadium under a single-band network. The square boxes represent the coverage area of the network. This single-band network uses slicing technology to cover the stands and competition area, with some wireless resources supporting 2B services and others supporting 2C services.
[0075] When it is determined that the network coverage requirement is not a single-band network, determine whether the 2B service requires stable and continuous coverage.
[0076] When it is determined that 2B services require stable and continuous coverage, macro base stations are used to implement stable coverage across all scenarios, and frequency yielding is performed on digital indoor distribution system sources or DAS indoor distribution system locations.
[0077] When it is determined that 2B services do not require stable and continuous coverage, determine whether dual-band networking is needed; when it is determined that dual-band networking is needed, adopt digital indoor distribution system source or DAS indoor distribution system point coverage to achieve refined coverage processing.
[0078] Specifically, when dual-band network coverage is available across all scenarios, a single carrier can be isolated to provide dedicated network protection to meet the needs of industry users. This independent carrier can be a discontinuous digital indoor distribution system or a macro base station coverage solution with continuous coverage but smaller capacity. The protection solution can be selected according to the actual needs of the industry. For example... Figure 6 The network coverage diagram for a large sports stadium implementing carrier isolation under dual-band networking to meet the needs of industry users is shown. The circular and square frames represent two different frequency band carriers. Carrier isolation separates the two carriers; the circular frame carrier guarantees the needs of industry users, while the square frame carrier meets the needs of general users. The two carriers can coexist in the same area, especially in the arena area. Using carrier isolation technology, general users and industry users on the two carriers can be strictly distinguished and isolated, ensuring that neither general users nor industry users occupy or use carriers that do not belong to them.
[0079] When it is determined that dual-band networking is not required, digital indoor distribution system sources or DAS indoor distribution system locations, as well as macro base stations, are used to achieve multi-point networking processing.
[0080] Specifically, when the entire scenario has dual-band or higher network coverage capabilities, a single carrier can guarantee the 2C needs of ordinary users on site. On two carriers, carrier isolation and discontinuous coverage with multiple handovers can be implemented, or RB resources can be reserved for flexible use. On the remaining three carriers, independent carriers can be enabled to implement continuous, high-quality network guarantees without handover.
[0081] Figure 7 A network coverage diagram for a large sports stadium implementing carrier isolation under a three-band network to meet the needs of industry users, as shown below. Figure 7 As shown, the circular, square, and pentagonal frames represent three frequency band carriers, respectively. The three carriers are separated by carrier isolation. The circular frame carrier ensures the needs of industry users, the square frame meets the needs of ordinary users, and the pentagonal frame is the remaining carrier among the three carriers. It can be used to enable independent carriers to implement continuous, high-quality network protection without handover, and meet other network needs of industry users and ordinary users. For example, it can meet the important live broadcast business needs of high-value industry users. Figure 7In this context, the square frame carriers used to ensure the needs of ordinary users should strive to cover the entire venue, while the circular frame carriers used to ensure the needs of industry users can cover the entire venue based on actual needs and costs.
[0082] Figure 8 A network coverage diagram for large sports stadiums, reserving resources for tri-band networking to meet the needs of industry users, is shown below. Figure 8 As shown, the circular, square, and pentagonal frames represent three frequency band carriers, respectively. Through carrier isolation, one carrier is dedicated to ordinary users in the stands (represented by a square frame in the diagram), meeting the 2C service requirements. Through RB resource reservation, a portion of the carrier within one band is separated for use by industry users and ordinary users, meeting the 2B2C service requirements. This involves separating the circular frame carrier into a left and right semi-circular frame. The left semi-circular frame carrier covers the stands and is used by ordinary users, while the right semi-circular frame carrier is used by industry users. Undivided circular frame carriers can also exist in the arena area. The remaining carriers from the three frequency bands are represented by pentagonal frames. These can be used to implement continuous, handover-free, high-quality network assurance, meeting other network requirements of industry users and ordinary users. For example, they can meet the important live streaming service requirements of high-value industry users.
[0083] In this embodiment, while ensuring high-quality 5G wireless network coverage, the high-density, heavy-load requirements of this scenario are met, the high interference problem in dense spaces is solved, and the needs of various 5G industries are taken into account, providing a guarantee solution for real-time data stream services such as live video streaming. It can ensure network perception for ordinary users with concentrated network access, and also meet the wireless network transmission needs of special industries in dense scenarios.
[0084] By using a multi-band networking scheme, without considering the load sharing of 4G networks, it is recommended that 5G networks use multiple frequency bands to achieve complex multi-band cross-networking within a limited space. In terms of services, through the combination of different frequency bands and carrier isolation, wireless isolation of 2C and 2B services of the wireless network is achieved, realizing reliable wireless transmission guarantee services, thereby achieving the purpose of multi-band networking.
[0085] In this embodiment, the high-density, heavy-load requirements of ordinary users are met, namely good coverage, controllable interference, and a good user experience. The business live streaming service needs of ordinary users in the 2C service are also met; specifically, this service requires a stable uplink speed of 2Mbps with minimal latency and jitter. Simultaneously, it can meet the video live streaming requirements of media, namely a stable uplink speed of over 50Mbps without handover, etc. Because the main services in large sports stadiums are concentrated in the uplink, uplink capacity requirements are a key reference design indicator for large sports stadiums. Therefore, in the 5G network design process, while ensuring controllable coverage and interference, the special applications of industry users need to be fully considered.
[0086] A detailed description of the system can be found in the previous embodiment, and will not be repeated here.
[0087] In this embodiment, by using digital indoor distributed system (DAS) signal sources or DAS signal sources located on the roof of the large stadium, at the top of the stands, at the edge of the stadium, at the macro base station signal source at the front edge of the high-rise stands, and with control equipment, carriers are separated throughout the entire scenario according to the network coverage requirements of the large stadium. This satisfies the 2B service needs of industry users and the 2C service needs of ordinary users. In addition, when the entire scenario has dual-band or higher network coverage capabilities, continuous, high-quality network assurance without handover can be achieved, meeting other network needs of industry users and ordinary users. Compared to existing technologies that use traditional indoor distributed antenna systems (DAS) or digital distributed antenna systems (DAS) for wireless network coverage, which rely on objective performance evaluations such as wireless network coverage requirements, edge field strength, and user perceived speed, typical indoor DAS systems share the wireless coverage network, competing for network resources. This application addresses this by installing digital DAS signal sources, DAS locations, macro base station signal sources, and control equipment within a large stadium. Based on the network coverage needs of the stadium, the application controls the digital DAS signal sources, DAS locations, and / or macro base station signal sources, comprehensively utilizing multiple systems, frequency bands, and devices to improve 5G network coverage quality and effectively reduce 5G network interference. This not only meets the high-density, heavy-load needs of ordinary users but also effectively addresses the specialized, customized support services of industry users, achieving reliable and stable 5G network service guarantees across all scenarios in large stadiums.
[0088] Figure 9 A flowchart illustrating an embodiment of a network coverage quality processing method provided in this application is shown below. Figure 9 As shown, this method is applied to large stadiums. Specifically, firstly, digital indoor distribution system (DAS) signal sources or DAS indoor distribution system points are installed at the building roof and the top of the stands of the large stadium; digital indoor distribution system signal sources are installed at the edge of the stadium; and macro base station signal sources are installed at the leading edge of the upper stands. The method includes the following steps:
[0089] Step S101: Control the device to obtain the network coverage requirements of the large stadium.
[0090] Step S102: The control equipment controls the digital indoor distribution system signal source, DAS indoor distribution system points and / or macro station signal source to perform corresponding network coverage processing according to the network coverage requirements of the large stadium.
[0091] 5G network coverage in the stands area will be achieved using on-site facilities. Specifically, digital distributed antenna system (DAS) sources or DAS points will be installed on building rooftops and the top of the stands. In indoor venues such as the National Stadium, it is recommended to use rooftop sources for coverage. Wireless network coverage in this area will be implemented in strict accordance with standard wireless network design requirements, effectively ensuring coverage and user experience. Wireless network coverage will be achieved with the support of DMM (Digital Multimedia Network) technology, ensuring capacity, reducing interference, and achieving a scale of 3000 seats per cell. The stands coverage will utilize maximum frequency resources to achieve 2-3 carrier frequency resource coverage, effectively providing wireless resources for the full-scenario implementation of 2B (Business to Consumer) and 2C (Business to Consumer) services while ensuring capacity.
[0092] Digital distributed antenna system (DAS) source units are installed at the perimeter of the site. These source units provide network coverage to the core area. The effective coverage distance of the digital DAS source units is approximately 60 meters. They are installed sequentially along the perimeter, with one source unit every 15 to 20 meters depending on site conditions. There are at least two source units on each side, totaling at least eight source units on all four sides. Specifically, two source units effectively mitigate the effects of obstruction, improve wireless network coverage, and achieve full-band coverage of the digital DAS system. Alternatively, macro base station source units can also be installed at the perimeter, generally with at least two units per frequency band, installed symmetrically.
[0093] Due to their higher ceiling height, macro base station equipment is suitable for installation in the ceiling area. Specifically, if the ceiling height of the stadium is greater than 30 meters, it is recommended to use macro base station equipment to cover the center of the arena. If the ceiling height is less than or equal to 30 meters, digital indoor distributed antenna systems (DAS) can be used to achieve network coverage in the center of the arena. When using digital DAS equipment to achieve network coverage in the center of the arena, use full-band or multi-band equipment, and the number of signal source points should be no less than two, depending on the actual space size and coverage requirements. When using macro base station equipment, it is recommended to use no less than two devices / frequency bands to achieve supplementary coverage and mutually ensure coverage of blind spots.
[0094] The front edge of the high-rise grandstand can be regarded as a backup location for the field edge and roof. Digital indoor distribution equipment cannot be installed at the front edge of the high-rise grandstand. For coverage and capacity supplementation at the center of the field, millimeter wave equipment can be installed to achieve inter-frequency networking and increase capacity. It is recommended that there be no less than 2 millimeter wave devices / frequency bands at this location.
[0095] The installation of equipment at the site's central enclosure location depends on requirements and site conditions. If the facility at this location suffers significant penetration damage (>30dB), no equipment should be installed there. If the penetration damage is manageable, a dense network can be implemented; however, this option is uncontrollable or has many limitations and is recommended as a secondary reference. If implementation is necessary, macro base stations and digital indoor distribution systems can be used for dense networking. If macro base stations and digital indoor distribution system signal sources are installed at the site's central enclosure, it is recommended to use at least two devices / frequency bands. The digital indoor distribution system signal source or macro base station antenna at the enclosure will transmit radio frequency signals upwards, penetrating the floor coverage facilities to achieve bottom-up network coverage.
[0096] The above installation locations can effectively achieve 5G coverage within the arena without affecting the stage design or the aesthetics of the venue. Furthermore, due to the different installation locations, there are different requirements for the installation process and hanging height at each location. Specifically, point 1 should be installed at a low height, with sturdy and compact mounting hardware. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion. Point 2 should also be installed at a low height, with sturdy and compact mounting hardware. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion, but the antenna itself should not be too large. Point 3 should be installed at a high position, as close as possible to the front edge of the ceiling. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion, requiring a relatively large tilt adjustment angle. Point 4 should be installed at a moderate position, with precise calculations required for the distance from the floor and the placement of the antenna. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion, and the equipment should be installed horizontally or facing the floor. For millimeter-wave antennas installed at point 5, they should be installed as close as possible to the front edge. The antenna should be able to rotate 360 degrees and be adjustable in both tilt and yaw motion, with a certain tilt adjustment angle, and the mounting hardware should be compact and aesthetically pleasing.
[0097] It applies the concept of distributed coverage networking using digital indoor distribution or traditional indoor distribution, and also involves the application of macro base stations in large sports stadium coverage scenarios. It not only meets the coverage and capacity requirements of high-density networking in large sports stadiums, but also enables continuous coverage in large spaces such as stadium stands and arenas, realizing multi-device networking and meeting the network needs of the media industry.
[0098] In various usable spaces such as stadium stands, building rooftops, arena perimeters, arena storage areas, and the front edge of stands, a wide range of multi-point coverage technologies are applied to meet the needs of different devices, locations, and requirements, as well as multiple backup 5G network solutions. This enables multi-dimensional application networking in large stadiums, achieving high, medium, and low-level three-dimensional coverage, and building a high-capacity, high-sensitivity, and multi-dimensional dense 5G network in relatively narrow spaces.
[0099] The application scenarios and specific descriptions of this method are described in the above embodiments, and will not be repeated here.
[0100] In this embodiment, the network coverage requirements of a large stadium are obtained through a control device. Based on these requirements, the control device controls the digital indoor distributed antenna system (DAS) source, DAS indoor distributed antenna system (DAS) locations, and / or macro base station sources to perform corresponding network coverage processing. Compared to existing technologies that use traditional indoor distributed antenna systems (DAS) or digital distributed antenna systems (DAS) for wireless network coverage, which rely on objective performance evaluations such as wireless network coverage requirements, edge field strength, and user perceived speed, resulting in competition for network resources between ordinary users and industry users, this application improves 5G network coverage quality and effectively reduces 5G network interference by installing digital indoor distributed antenna system (DAS) sources, DAS indoor distributed antenna system (DAS) locations, macro base station sources, and control devices within the large stadium. This allows for the comprehensive use of multiple systems, frequency bands, and devices to meet the high-density, heavy-load needs of ordinary users while effectively addressing the specialized support services required by industry users, thus achieving reliable and stable 5G network service guarantees across all scenarios in the large stadium.
[0101] Figure 10 This is a flowchart illustrating a second embodiment of a network coverage quality processing method provided in this application, applied to a large stadium. Specifically, firstly, digital indoor distribution system (DAS) signal sources or DAS indoor distribution system points are installed at the building roof and the top of the stands of the large stadium; digital indoor distribution system signal sources are installed at the edge of the stadium; and macro base station signal sources are installed at the leading edge of the upper stands of the large stadium. The method includes the following steps:
[0102] Step S201: Control the device to obtain the network coverage requirements of the large stadium.
[0103] Step S202: Determine whether the network coverage requirement is a single-frequency band network. If yes, proceed to step S203; otherwise, proceed to step S204.
[0104] Step S203: Use slicing technology to isolate 2B2C business slices.
[0105] In this embodiment, when only single-band networking capability is available across the entire scenario, digital indoor distribution coverage is implemented, and slicing technology is used to ensure industry needs are met. This single-band network, through slicing technology, completes network coverage for the grandstand and arena areas, with a portion of wireless resources supporting 2B services and a portion supporting 2C services.
[0106] Step S204: Determine whether the 2B service requires stable and continuous coverage. If yes, proceed to step S205; otherwise, proceed to step S206.
[0107] Step S205: Implement stable coverage across all scenarios using macro base stations, and perform frequency yielding processing on digital indoor distribution system signal sources or DAS indoor distribution system locations.
[0108] Step S206: Determine whether dual-band networking is required. If yes, proceed to step S207; otherwise, proceed to step S208.
[0109] Step S207: Use digital indoor distribution system sources or DAS indoor distribution system point coverage to achieve refined coverage processing.
[0110] In this embodiment, when the dual-band network coverage capability is available in the entire scenario, a single carrier can be isolated to implement private network protection in order to meet the needs of industry users. The independent carrier can be a digital indoor distribution system with discontinuous coverage or a macro base station coverage scheme with continuous coverage but small capacity. The protection scheme can be selected according to the actual needs of the industry.
[0111] Step S208: Use digital indoor distribution system sources or DAS indoor distribution system locations, as well as macro base stations to achieve multi-point networking processing, and realize the application of flexible networking technology with multi-carrier isolation and slicing.
[0112] In this embodiment, when the entire scenario has dual-band or higher network coverage capability, the 2C needs of ordinary users on site can be guaranteed with a single carrier. Carrier isolation and discontinuous coverage with multiple handover networks can be implemented on two carriers, or RB resources can be flexibly reserved and used. On the remaining three carriers, independent carriers can be enabled to implement continuous and handover-free high-quality network guarantee.
[0113] In this embodiment, while ensuring high-quality 5G wireless network coverage, the high-density, heavy-load requirements of this scenario are met, the high interference problem in dense spaces is solved, and the needs of various 5G industries are taken into account, providing a guarantee solution for real-time data stream services such as live video streaming. It can ensure network perception for ordinary users with concentrated network access, and also meet the wireless network transmission needs of special industries in dense scenarios.
[0114] By using a multi-band networking scheme, without considering the load sharing of 4G networks, it is recommended that 5G networks use multiple frequency bands to achieve complex multi-band cross-networking within a limited space. In terms of services, through the combination of different frequency bands and carrier isolation, wireless isolation of 2C and 2B services of the wireless network is achieved, realizing reliable wireless transmission guarantee services, thereby achieving the purpose of multi-band networking.
[0115] In this embodiment, the high-density, heavy-load requirements of ordinary users are met, namely good coverage, controllable interference, and a good user experience. The business live streaming service needs of ordinary users in the 2C service are also met; specifically, this service requires a stable uplink speed of 2Mbps with minimal latency and jitter. Simultaneously, it can meet the video live streaming requirements of media, namely a stable uplink speed of over 50Mbps without handover, etc. Because the main services in large sports stadiums are concentrated in the uplink, uplink capacity requirements are a key reference design indicator for large sports stadiums. Therefore, in the 5G network design process, while ensuring controllable coverage and interference, the special applications of industry users need to be fully considered.
[0116] The application scenarios and specific descriptions of this method are described in the above embodiments, and will not be repeated here.
[0117] In this embodiment, by using digital indoor distributed system (DAS) signal sources or DAS signal sources located on the roof of the large stadium, at the top of the stands, at the edge of the stadium, at the macro base station signal source at the front edge of the high-rise stands, and with control equipment, carriers are separated throughout the entire scenario according to the network coverage requirements of the large stadium. This satisfies the 2B service needs of industry users and the 2C service needs of ordinary users. In addition, when the entire scenario has dual-band or higher network coverage capabilities, continuous, high-quality network assurance without handover can be achieved, meeting other network needs of industry users and ordinary users. Compared to existing technologies that use traditional indoor distributed antenna systems (DAS) or digital distributed antenna systems (DAS) for wireless network coverage, which rely on objective performance evaluations such as wireless network coverage requirements, edge field strength, and user perceived speed, typical indoor DAS systems share the wireless coverage network, competing for network resources. This application addresses this by installing digital DAS signal sources, DAS locations, macro base station signal sources, and control equipment within a large stadium. Based on the network coverage needs of the stadium, the application controls the digital DAS signal sources, DAS locations, and / or macro base station signal sources, comprehensively utilizing multiple systems, frequency bands, and devices to improve 5G network coverage quality and effectively reduce 5G network interference. This not only meets the high-density, heavy-load needs of ordinary users but also effectively addresses the specialized, customized support services of industry users, achieving reliable and stable 5G network service guarantees across all scenarios in large stadiums.
