Technical Field

[0001] The utility model relates to the field of wireless technology, in particular to a closed-route indoor household construction system. Background Art

[0002] Perception issues are prominent in residential areas, with poor quality scenes and a high proportion of complaints, mainly due to local weak indoor coverage. Due to the towering and densely packed buildings in the city, local weak indoor coverage is caused, and sampling points are concentrated in high-rise buildings and local areas of large apartments. Existing operators have the following three main ways to solve indoor complaints in residential areas:

[0003] 1) PDAS (Personal Area Network Service) is a wireless network technology based on mobile communication networks. It further improves the data transmission rate and stability by providing split transmission based on the existing 2G / 4G / 5G networks. The advantages of PDAS include the ability to quickly solve the problem of weak coverage in the basement. PDAS supports optical fiber extension and can connect up to 8 remote units, and the remote units have high power. 2) Full Range Boost is a new type of wireless network technology that uses high-power amplifiers and dual-band technology to provide strong signal coverage over a larger range. The advantages of Full Range Boost include wide coverage, stable signal strength, and strong penetration. 3) Femto is a very small wireless network device that provides very weak wireless signals through home broadband network access to the network to ensure user privacy.

[0004] The disadvantages of the above three communication devices are: PDAS devices are connected through near-end, far-end and intermediate optical fibers, resulting in high equipment costs; Mangebao devices easily increase network noise by amplifying the 2 / 4 / 5G signals of existing base stations and are not aesthetically pleasing when deployed indoors; Femto devices rely on home broadband networks and occupy home bandwidth, which can easily cause a decline in QOS quality, especially since the activation of 5G signals requires support for network gigabit bandwidth.

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The following describes the closed-route indoor home construction system of an embodiment of the utility model with reference to the accompanying drawings.

[0038] Figure 2 A schematic diagram of the structure of a closed-route indoor household construction system provided in an embodiment of the utility model.

[0039] like Figure 2 As shown, a closed-route indoor distribution home construction system 10 includes a first RRU device 100, a first coupler 200, a first adapter 300, a first connector 400, a second adapter 500, and a first patch antenna 600; wherein,

[0040] The first RRU device 100 is used to connect one end of the first coupler 200 through a 1 / 2 feeder line;

[0041] One end of the first adapter 300 is connected to the other end of the first coupler 200 , and the other end of the first adapter 300 is connected to one end of the first connector 400 ;

[0042] The other end of the first connector 400 is used to connect to one end of the second adapter 500 , and the other end of the second adapter 500 is connected to one end of the first patch antenna 600 .

[0043] For example, the indoor distributed system of the present invention is an existing indoor distributed system mainly composed of BBU, RRU, DAS, DRA, optical fiber and feeder. BBU and RRU are connected by optical fiber, RRU is connected to DAS by 1 / 2 feeder, and DRA (power divider, coupler) and other passive devices are passed in between. Figure 1 shown.

[0044] The technical terms mentioned in this utility model are shown in Table 1:

[0045] Table 1

[0046]

[0047] It is understandable that the design of the indoor distribution system (indoor distribution system) is to solve the problem of mobile communication signal coverage in areas such as large buildings and underground spaces, ensuring that indoor users can obtain high-quality communication services.

[0048] It is understandable that BBU (Baseband Unit) is the core processing unit in the indoor distributed system, responsible for baseband signal processing, including signal encoding, decoding, modulation, demodulation and other operations. In modern communication systems, BBU is often located in a more centralized location, perhaps in a data center or communication room.

[0049] It is understandable that the RRU (Remote Radio Unit) is placed near or in the area where signal coverage needs to be enhanced. It is responsible for converting the baseband signal transmitted by the BBU into a radio frequency signal, amplifying it and transmitting it through the antenna, or receiving the radio frequency signal from the terminal and transmitting it back to the BBU for processing. The RRU and BBU are connected by optical fiber, using protocols such as CPRI or eCPRI, which reduces signal loss and interference in traditional copper wire transmission.

[0050] It is understood that DAS (Distributed Antenna System) is a network of multiple antenna nodes used to disperse wireless signals in indoor environments. RRU is connected to DAS via 1 / 2-inch feeder (coaxial cable) to ensure that the signal can be effectively transmitted to each antenna point.

[0051] It is understandable that DRA (Distributed Radio Amplifier) ​​is a RF amplification technology that is different from the traditional centralized amplifier design and is mainly used in RF and microwave systems that require high power output, wide bandwidth and low noise. The design of distributed amplifiers is based on transmission line theory, using multiple amplification units (usually called "stages") distributed along the transmission line, and each unit amplifies the signal to a certain extent. These amplification units can be transistors, field effect transistors (such as GaAs FETs) or other active devices, which are designed to work efficiently over a wide bandwidth while maintaining signal stability and low distortion.

[0052] It is understandable that the connection between BBU and RRU mainly relies on optical fiber and feeder. This is because optical fiber has the advantages of high bandwidth, low loss, and anti-electromagnetic interference, which is suitable for long-distance, high-speed data transmission. The connection from RRU to DAS usually uses coaxial cable (feeder), such as 1 / 2-inch feeder, which can effectively transmit RF signals to each antenna node. In summary, the indoor distributed system achieves efficient transmission and distribution of signals from the base station to the indoor through the collaborative work of these components, ensuring that indoor users can obtain a stable mobile communication experience.

[0053] It can be understood that a coupler is a device used in the field of electronics and communications to distribute or combine signal energy. It can transfer signals between different circuits or systems while allowing the signals to remain isolated to some extent. There are many types of couplers, including but not limited to optocouplers, RF couplers, power couplers, etc., which play an important role in their respective application scenarios. The following is a brief overview of several common types of couplers and their functions: Optocoupler: Optocouplers use light as a medium to transmit electrical signals to achieve electrical isolation. It consists of a light-emitting element (usually a light-emitting diode LED) and a photosensitive element (such as a photodiode or phototransistor), located in the same package but electrically isolated. Optocouplers are often used to prevent high voltage or noise from affecting the output side from the input side, and are widely used in circuit isolation, signal conversion and noise suppression. RF coupler: In RF and microwave communication systems, couplers are used to split one signal into multiple channels, or to combine multiple signals into one channel, while controlling the power distribution of each signal. They can be directional couplers, used to couple a small portion of the signal from the main transmission path for monitoring, or power dividers / combiners, used to distribute power evenly or unevenly. Power coupler: In power transmission and distribution systems, power couplers are used to transfer power from one circuit to another, and are often used for energy distribution or merging. In fiber-optic communications, couplers are also used to distribute and combine optical signals to achieve signal routing in optical networks. Important performance indicators of couplers include coupling (indicating the ratio of signal strength coupled from the main line to the branch line), insertion loss (power loss when the signal passes through the coupler), directivity (the ability of the coupler to distinguish between input and output signals), isolation (the degree of signal isolation between the two output ports), and operating frequency range. Selecting the right coupler type and parameters is crucial to ensuring system performance, improving stability, and isolating interference.

[0054] It is understandable that in the field of radio communications, cable TV systems, and some network cabling, different types of connectors are used to match cables and devices of different standards. The metric F female to N female converter refers to an adapter used to convert devices or cables using metric F-type interfaces (commonly used for coaxial cable connections for cable TV and some wireless devices) to devices or systems using N-type interfaces (commonly used in RF applications, microwave communications, and some high-performance wireless devices). Metric F female: commonly used to connect coaxial cables for satellite TV receivers, cable TV systems, and some home networks. The F-type interface is known for its threaded connection and common conical shell and is widely used in television signal transmission. N female: a connector with higher frequency performance, designed to withstand higher power and frequency ranges, commonly found in professional radio equipment, microwave communication systems, laboratory test equipment, etc. The N-type interface provides better shielding and lower signal loss than the F-type, and is suitable for high-frequency signal transmission. Therefore, the "metric F female to N female" adapter is designed to make these two different standard interfaces compatible, so that the device or cable can be connected to the system requiring an N-type interface through the conversion adapter while retaining the original F-type end connection, thereby improving the interoperability and flexibility of the device.

[0055] It is understandable that closed-circuit connectors usually refer to connectors used to connect coaxial cables, which are widely used in cable TV, satellite TV, closed-circuit television surveillance systems, and certain types of network cabling. There are several common types of closed-circuit connectors, including: F-type connector: It is the most common closed-circuit connector, divided into F male (usually connected to the device end) and F female (usually connected to the cable end). F-type connectors are used to connect devices such as TVs, modems, and cable boxes. BNC connector: Commonly used in video surveillance systems, professional audio, and some old-fashioned network equipment. BNC connectors provide a locking mechanism to ensure the stability of the connection. N-type connector: Mainly used for high-frequency transmission, microwave communication, and some high-performance wireless devices, with good shielding performance and low loss characteristics. SMA connector (SubMiniature version A): Suitable for high-frequency wireless devices, such as WiFi antennas, GPS receivers, etc., there are SMA male and SMA female connectors.

[0056] It can be understood that the SMA female to metric F female is an adapter or converter used to connect coaxial cables or devices with different interface types. Specifically: SMA (SubMiniature version A) is a small coaxial connector widely used in wireless communications, satellite communications, and some radio frequency devices. It is small in size and has good frequency performance. SMA interfaces are divided into male and female, where the female refers to a component with internal contact pins and external threaded interfaces. Metric F female is mainly used for coaxial cable connections in systems such as cable television (CATV), satellite TV reception, and closed-circuit television (CCTV). The metric F interface usually refers to an external thread connector used with coaxial cables. Here, "metric" means that its thread specifications follow the internationally accepted metric standard, while "female" means that the connector has internal threads and contact holes for receiving male plugs. Therefore, the role of the "SMA female to metric F female" adapter is to convert the SMA female interface on a device into an interface that accepts a metric F female connector, so that two different types of coaxial cables or devices that cannot be directly connected can be connected to each other. This type of adapter is very useful when you need to mix communication devices of different standards or during specific system upgrades and modifications, and can flexibly adapt to different connection requirements.

[0057] like Figure 3 As shown, the RRU located in the weak current well (corresponding to Figure 2 The first RRU device 100) is connected to the coupler (corresponding to Figure 2 The first coupler 200), metric F female to N female (corresponding Figure 2 The first adapter 300) is directly connected to the coupler at one end (corresponding to Figure 2 The first coupler 200 of the embodiment of the present invention is connected to the first closed-circuit connector (corresponding to the first closed-circuit connector of the embodiment of the present invention). Figure 2 The closed-circuit connector is connected to the weak-current box in the user's home through the closed-circuit pre-buried in the wall by the developer. Since the patch antenna supports N male and metric F female, the metric F female is connected to the N male or the SMA female to the metric F female at the node of the closed-circuit of the weak-current box (corresponding to Figure 2 The second adapter 500) is directly connected to the patch antenna (corresponding to Figure 2 first patch antenna 600).

[0058] The closed-route indoor home construction system of this embodiment is limited by the gain effect of the patch antenna, and the single patch antenna direct connection solution is only applicable to houses with local weak coverage or houses smaller than 75 square meters.

[0059] The closed-line-based indoor home construction system of this embodiment utilizes closed-line transmission of radio frequency signals to achieve wireless signal access to homes without damaging the indoor structure of the owner, thereby greatly saving construction costs and reducing the difficulty of indoor home access. In addition, in view of the problem that the existing network uses a large amount of optical fiber transmission, resulting in idle closed-line resources, closed-line transmission of wireless signals is used to recycle physical resources. Compared with existing solutions, this embodiment does not require the use of the owner's home power supply. It saves resources and is easy for users to accept.

[0060] Figure 4 A schematic structural diagram of another closed-route indoor household construction system provided in an embodiment of the utility model.

[0061] like Figure 4 As shown, the indoor distribution home construction system 20 based on the closed route includes: a second RRU device 30, a second coupler 40, a third adapter 50, a second connector 60, a fourth adapter 70, a fifth adapter 80 and a second patch antenna 90; wherein,

[0062] The second RRU device 30 is used to connect one end of the second coupler 40 through a 1 / 2 feeder line;

[0063] One end of the third adapter 40 is connected to the other end of the second coupler 40 , and the other end of the third adapter 50 is connected to one end of the second connector 60 ;

[0064] The other end of the second connector 60 is used to connect to one end of the fourth adapter 70, and the other end of the fourth adapter 70 is used to connect to one end of the fifth adapter 80;

[0065] The other end of the fifth adapter 80 is used to connect to one end of the second patch antenna 90 .

[0066] It is understandable that the second RRU device 30 is located in the existing indoor distributed system, which is consistent with the above description and will not be further explained in this embodiment.

[0067] It can be understood that the second coupler 40, the third adapter 50, the second connector 60, and the fifth adapter 80 of this embodiment are consistent with the descriptions of the first coupler 200, the first adapter 300, the first connector 400, and the second adapter 500 corresponding to the above-mentioned embodiment, so no unnecessary explanation is given in this embodiment.

[0068] Exemplarily, the third adapter 50 may include any type of metric F female to N female adapter.

[0069] Exemplarily, the fifth adapter 80 may include any type of a metric F female to N male and a SMA female to a metric F female.

[0070] Exemplarily, the fourth adapter 70 may include one of a one-to-two connector, a one-to-three connector, and a TV three-way direct female connector.

[0071] It is understandable that a 1-to-2 connector usually refers to an adapter or splitter that can split an input source to two output ends. This connector is more common in various electronic devices and signal transmission fields, especially in audio, video signal distribution, and network wiring. In different fields, the form and name of the 1-to-2 connector may be different: Coaxial cable 1-to-2 connector: In cable TV, satellite TV or closed-circuit television systems, a device called a 1-to-2 splitter may be used. It has an input port (usually an F-type interface) and two output ports for distributing a signal source to two different display devices or receivers. Audio 1-to-2 connector: In the audio field, this connector allows an audio output device (such as an MP3 player, computer sound card) to be connected to two audio input devices (such as two headphones or two speakers). This connector may use a 3.5mm headphone plug to two 3.5mm headphone sockets. HDMI 1-to-2 splitter: In high-definition video transmission, an HDMI 1-to-2 splitter can distribute an HDMI signal source (such as a Blu-ray player, game console) to two HDMI displays or TVs, realizing the synchronous transmission of video and audio signals. Network 1-to-2 cable: In Ethernet cabling, although direct "1-to-2" connectors are uncommon, network 1-to-2 splitters or hubs can be used to achieve the function of connecting two devices to one network port. When selecting and using a 1-to-2 connector, it is necessary to consider the attenuation and quality of the signal to ensure that the selected connector or splitter can meet the requirements of signal transmission and will not cause signal quality degradation or interference. In some high-frequency or high-bandwidth applications, it may also be necessary to consider a signal amplifier to ensure the complete transmission of the signal.

[0072] It is understandable that a 1-to-3-way connector usually refers to an adapter or splitter that can divide a single input source into three outputs. This type of connector is used in a variety of electronic devices and signal transmission fields, and its main purpose is to achieve signal distribution. Depending on different usage scenarios, a 1-to-3-way connector can have various forms and uses.

[0073] It can be understood that the TV three-way direct female connector is an accessory for signal distribution or connection extension. Specifically, the TV three-way is a connection device that is usually used to split a signal source to two different outputs, or to merge two signal sources into one output. The direct female connector may refer to one end of this three-way device directly connected to the female connector of the TV, set-top box or other signal source to ensure the transmission of the signal. In specific applications, the TV three-way generally has the following characteristics: Interface type: The standard F-type interface is usually adopted, because this is a common connection method in cable TV and some home audio-visual equipment. Function: It can be a one-female to two-male structure, that is, one female connector connects to the signal source, and two male connectors connect to two receiving devices respectively, or one male to two female connectors, which is used to merge two signal sources into one output. It should be noted that the direct female connector usually refers to the interface directly connected to the signal source device, ensuring that the output of the signal source can be seamlessly connected to the three-way device, and then distributed to other devices.

[0074] like Figure 5 As shown, the RRU equipment located in the weak current well (corresponding to Figure 4 The second RRU device 30 in the embodiment is connected to the coupler (corresponding to Figure 4 The second coupler 40 in the metric F female connector to N female connector (corresponding to Figure 4 The third adapter 50) is directly connected to the coupler at one end (corresponding to Figure 4 The second coupler 40 in the other end is directly connected to the closed-circuit joint, that is, the second closed-circuit joint (corresponding to Figure 4 The closed-circuit connector is connected to the weak-current box in the user's home through the closed-circuit pre-buried in the wall by the developer; for large-sized houses (>=75㎡), a one-to-two connector or a one-to-three connector or a TV three-way direct female connector (corresponding to the closed-circuit interface of the weak-current box) is connected. Figure 4 The other end is connected to the metric F female to N male or SMA female to metric F female (corresponding to Figure 4 One end of the fifth adapter 80 in the middle, the other end of the metric F female to N male or SMA female to metric F female is connected to multiple patch antennas (corresponding to Figure 4 The second patch antenna 90 in the embodiment.

[0075] It is understandable that the indoor home construction plan based on closed-line must meet three prerequisites: ① The building has deployed the operator's indoor distribution system and has flat-floor coverage; ② The user's home has idle closed-line resources; ③ The existing indoor terminal power margin is greater than 10db (the antenna power calculation formula is: Pr = Pt × Gt × Gr / Ld. Among them, Pr is the received power, Pt is the transmission power of the source point, Gt is the gain of the transmitting antenna, Gr is the gain of the receiving antenna, and Ld is the free space attenuation of the downlink).

[0076] Based on this, based on actual application life, users complained that the coverage level on site was extremely poor or disconnected, calls were obviously intermittent, and often fell back to 2G, which seriously affected data services. Located in Room 1302, Building 5 of the resettlement house. There are 6 buildings in the community, distributed in double rows. The complaint point is located on the top floor, and the flat coverage is achieved in the elevator hall, without entry, the surrounding sites are low and far away, the indoor living room coverage level is below -100, and the bedroom occupies the surrounding sites. The signal is extremely weak and disconnected. On-site investigation, the closed-circuit line at this point enters the house to the wall wire box in the living room, and no wiring is reserved to each room. The indoor wiring box is located on the left side of the entrance, under the wall. The indoor distribution system’s nearest terminal antenna can be connected to the coupler and the closed-circuit wire wiring relay are both located in the weak current well next to the elevator shaft on the 12th floor. This point belongs to the terminal antenna coverage of the original indoor distribution system, so the coupling connection considers the direct-through end to connect to the closed route through the N female connector to the F female connector, the entry connection patch antenna covers the indoor, and the coupling section connects to the original terminal antenna to ensure the coverage of the elevator hall.

[0077] The indoor home access construction system based on closed routes according to the present embodiment can improve the user's indoor signal coverage strength and solve the limitations of the existing technology. Without damaging the owner's indoor structure, wireless signals can be introduced into the home, which greatly saves construction costs and reduces the difficulty of indoor home access. At the same time, from the user's perspective, it is simple, convenient, easy to accept, and the equipment is beautiful; from the network perspective, it is convenient to construct, low in cost, easy to maintain, and has strong equipment expandability.

[0078] The beneficial effects of the utility model include:

[0079] 1) Convenient construction and on-demand deployment: The maintenance personnel are equipped with feeder construction and transformation technology. According to user complaints, they will conduct on-site inspections and start construction if conditions are met, without the need for a second on-site service.

[0080] 2) Self-contained power supply: powered by feeder, no need to use the owner's power supply;

[0081] 3) Beautiful entrance: The entrance device is only a patch antenna, which is small, flexible and can be hidden behind a TV cabinet; low cost: the overall construction cost and device cost does not exceed 150 yuan; only 1 / 10 of the cost of existing technical solutions.

[0082] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
