Description

A New Distributed Base Station

Technical Field

The present application relates to the field of communication technology, and in particular to a new type of distributed base station.

Background technique

In order to ensure good coverage of the fifth generation mobile communication technology (5G) network, a large number of 5G distributed base stations need to be deployed indoors. 5G distributed base stations usually include: omnidirectional antennas and log-periodic antennas. Omnidirectional antennas, as the name implies, radiate uniformly at 360° in the horizontal direction and are usually called non-directional antennas. Omnidirectional antennas have a shorter coverage distance due to their low gain, and large-scale deployment is very likely to result in a waste of investment.

Compared with omnidirectional antennas, log-periodic antennas have stronger gain effects and the strongest penetration, but the negative effects they bring are also obvious. In addition to the strong gain in the main lobe direction, the signal attenuation in the side lobes is obvious, which limits its use scenarios and cannot be applied on a large scale. It can only be used in limited scenarios such as elevators and underground parking lots.

Therefore, how to ensure the surface coverage of indoor base stations in multiple scenarios while taking into account targeted deep point coverage has become a technical problem that needs to be solved urgently.

Utility Model Content

The present application provides a new type of distributed base station, which is used to solve the problem that indoor base stations in related technologies cannot simultaneously achieve signal surface coverage and targeted deep point coverage.

The present application provides a new type of distributed base station, including: a shell, an omnidirectional coverage antenna device and multiple log-periodic antenna devices, wherein the new type of distributed base station includes a shell, an omnidirectional coverage antenna device and multiple log-periodic antenna devices, the omnidirectional coverage antenna device is arranged in a receiving cavity, and the omnidirectional coverage antenna device is used to form an omnidirectional signal in a horizontal azimuth plane; the multiple log-periodic antenna devices are all arranged in the receiving cavity and are located on the same side of the omnidirectional coverage antenna device; the multiple log-periodic antenna devices are arranged in a ring shape at intervals, and the polarization directions of the multiple log-periodic antenna devices are all set outward.

The new distributed antenna in the present application includes: a shell, an omnidirectional coverage antenna device and multiple log-periodic antenna devices. Among them, the new distributed base station includes: a shell, an omnidirectional coverage antenna device and multiple log-periodic antenna devices, wherein the omnidirectional coverage antenna device is arranged in a receiving cavity, and the omnidirectional coverage antenna device is used to form an omnidirectional signal in the horizontal azimuth plane. Multiple log-periodic antenna devices are all arranged in the receiving cavity and are located on the same side of the omnidirectional coverage antenna device; multiple log-periodic antenna devices are arranged in a ring shape, and the polarization directions of the multiple log-periodic antenna devices are all set outward. The new distributed base station of the present application is used to establish a communication connection.

In this way, the new distributed base station can form an omnidirectional signal in the horizontal azimuth plane through an omnidirectional coverage antenna device, and can cover the signal depth point through multiple logarithmic periodic antenna devices. In addition, the new distributed base station can also effectively reuse the deployment points of the existing fourth generation mobile communication technology (4G) indoor distribution system, thereby saving investment costs. The transmission and power supply equipment of the new distributed base station can realize the rapid opening of the base station, thereby saving construction time and improving efficiency.

In a possible implementation, multiple log-periodic antenna devices are evenly distributed in a ring shape. In this way, the polarization directions of the multiple log-periodic antenna devices are evenly distributed in a ring shape in different directions, thereby ensuring that the surrounding positions of the new distributed antenna can achieve deep point coverage of the signal. In addition, it can avoid a certain position being located in the gain direction of multiple log-periodic antennas, resulting in a waste of resources.

In a possible implementation, the number of the log-periodic antenna devices is 8. In this way, any two of the 8 log-periodic antennas are arranged at a 45-degree interval. When it is necessary to locate an electronic device within the signal range of the new distributed base station, the coordinate position of the electronic device can be constructed through the 8 log-periodic antennas, thereby facilitating the positioning of the electronic device.

In a possible implementation, the new distributed base station also includes: an optoelectronic composite cable, which is electrically connected to both the omnidirectional coverage antenna device and the log-periodic antenna device, and is used to establish power and communication connections with the omnidirectional coverage antenna device and the log-periodic antenna device.

Since the optical fiber composite cable integrates optical fiber and power transmission copper wire, it can solve the problems of broadband access, equipment power consumption, and signal transmission. The new distributed base station does not need to set up two lines (one for transmitting power and one for establishing communication connections), which is conducive to reducing the cost of base station construction.

In a possible implementation, the omnidirectional coverage antenna device includes: a first interface; the multiple log-periodic antenna devices each include: a second interface, and the first interface and the multiple second interfaces are all electrically connected to the optoelectronic composite cable.

In this way, the optoelectronic composite cable can be electrically connected to the log-periodic antenna device and the omnidirectional coverage antenna device respectively, thereby avoiding the setting of a single optoelectronic composite cable electrically connected to both the log-periodic antenna device and the omnidirectional coverage antenna device, which would cause network congestion.

In a possible implementation, the second interface is disposed in the housing, and the second interface is disposed on the side opposite to the polarization direction of the log-periodic antenna device. In this way, the second interface is disposed in the housing and is located on the side opposite to the polarization direction of the log-periodic antenna device, and the distance between the second interfaces of the multiple log-periodic antennas is relatively close, so that it is convenient to connect the optical composite cable to the multiple second interfaces.

In a possible implementation, the optoelectronic composite cable includes: a first optoelectronic composite cable and a second optoelectronic composite cable, wherein the first optoelectronic composite cable is electrically connected to the first interface and is used to establish a power and communication connection with the omnidirectional coverage antenna device; and the second optoelectronic composite cable is electrically connected to the second interface and is used to establish a power and communication connection with the log-periodic antenna device. Thus, it is avoided that a single optoelectronic composite cable is electrically connected to both the log-periodic antenna device and the omnidirectional coverage antenna device, which may cause network congestion.

In a possible implementation, the log-periodic antenna device further includes: a main interface, the second interfaces of the plurality of log-periodic antenna devices are all electrically connected to the main interface, and the main interface is electrically connected to the second optoelectronic composite cable. In this way, the second optoelectronic composite cable only needs to be connected to the main interface to achieve electrical connection with the second interfaces of the plurality of log-periodic antenna devices, which is convenient for installation and use.

In a possible implementation, the omnidirectional coverage antenna device and the logarithmic periodic antenna device both include: a radio frequency device, which can support 850M, 1800M, 2100M, 2600M or 4900M frequency bands. In this way, the new distributed base station can support multiple frequency bands.

With the rapid development of the information society and the improvement of people's living standards, 5G networks have been rapidly popularized. The most important features of 5G networks are larger network bandwidth, lower latency requirements and more network connections. 5G communications have brought about rapid growth in wireless traffic due to their high operating frequency band and large transmission bandwidth. However, the current deployment of 5G networks mainly adopts the traditional 4G network construction method. The 5G frequency band is generally higher, making it difficult for existing indoor distribution systems to meet the 5G frequency requirements.

The traditional 5G network construction idea solves the coverage blind spots by building new base stations. However, the current domestic 5G network generally operates in a higher frequency band (2.6GHz or 4.9GHz), so the indoor signal coverage requires a dedicated indoor base station. For traditional indoor scenarios, indoor distributed base stations are usually used for coverage. The current mainstream method is to use fiber-optic distributed indoor base stations. Each device of the fiber-optic distributed indoor base station is an antenna coverage point, so in order to achieve a better coverage effect, a large number of distributed base stations need to be deployed indoors. Since the price of 5G distributed base stations is more than several times higher than that of the original 4G ordinary antennas, and the power consumption is also higher, the construction investment and operating costs for operators and owners are greatly increased compared to the 4G indoor distribution solution, which has greatly hindered the scale and progress of 5G indoor construction.

The current distributed base stations mainly include: traditional omnidirectional antennas, traditional indoor directional antennas and log-periodic antennas.

The deployment of traditional omnidirectional antennas is still common in today's 5G network construction. Omnidirectional antennas, as the name suggests, radiate uniformly at 360° in the horizontal direction and are usually called non-directional antennas. Omnidirectional antennas have a low gain and a short coverage distance, and large-scale deployment can easily lead to a waste of investment.

Traditional indoor directional antennas are commonly known as small plate antennas, which are mainly distributed in areas that require deep coverage, such as classrooms and cinemas. The penetration effect of this indoor directional antenna is much better than that of traditional omnidirectional antennas, with a smaller lobe angle and high gain. However, there are still disadvantages of limited installation conditions, and the appearance is not concealed enough, without beautification effect, and the installation of base stations is quite difficult.

Compared with the above two antennas, the log-periodic antenna has a stronger gain effect and the strongest penetration, but the negative impact it brings is also obvious. In addition to the strong gain in the main lobe direction, the signal attenuation in the side lobe is obvious, which limits its use scenarios and cannot be applied on a large scale. It can only be used in limited scenarios such as elevators and underground parking lots.

Therefore, how to ensure the surface coverage of indoor base stations in multiple scenarios while taking into account targeted deep point coverage has become a technical problem that needs to be solved urgently.

The present application provides a new type of distributed base station, which is used to solve the problem in the related art that the indoor base station cannot simultaneously achieve signal surface coverage and targeted deep point coverage.

Figure 1 shows a top view of a new type of distributed base station provided in an embodiment of the present application with the shell removed. As shown in Figure 1, the new type of distributed base station 100 may include: a shell 10 (not shown in Figure 1), an omnidirectional coverage antenna device 20 and multiple log-periodic antenna devices 30.

FIG2 shows a schematic diagram of a three-dimensional structure of a housing provided in an embodiment of the present application, FIG3 shows one of the cross-sectional views of FIG2 along the A-A direction provided in an embodiment of the present application, and FIG4 shows a second cross-sectional view of FIG2 along the A-A direction provided in an embodiment of the present application, wherein FIG3 and FIG4 are cross-sectional views of FIG2 on opposite sides along the A-A direction, as shown in FIG2, FIG3 and FIG4, a housing cavity 11 is provided in the housing 10, and the housing cavity 11 may include: a first housing cavity 111 and a plurality of second housing cavities 112. The first housing cavity 111 may be connected to the plurality of second housing cavities 112.

In a possible structural design, the housing 10 may include: a base and a cover, the cover is covered on the base to form the housing 10, a plurality of second accommodating cavities 112 are provided on the side wall of the base facing the cover, and a first accommodating cavity 111 is provided on the side wall of the cover facing the base. The cover is covered on the base, and the second accommodating cavity 112 is communicated with the first accommodating cavity 111.

Exemplarily, the shape of the first accommodating cavity 111 may be a cylindrical structure, or the shape of the first accommodating cavity 111 may be a cube structure, which is not limited in the present application.

The shapes of the plurality of second accommodating chambers 112 may be the same or different and may be arranged as required. For example, the shape of the second accommodating chamber 112 may be a triangular prism or a rectangular parallelepiped structure, which is not limited in the present application.

In order to reduce the volume of the shell, in a possible implementation, the side wall of the shell that encloses the second accommodating cavity 112 can be arranged to be raised. In this way, the shell 10 occupies a smaller space, which is conducive to the miniaturization of the new distributed base station 100.

In another possible structural design, the housing 10 may also include: a housing portion 12 and a covering portion. FIG5 shows a top view of a housing portion 12 of a housing provided in an embodiment of the present application. As shown in FIG5 , a first housing groove 121 is provided on the housing portion 12, and a plurality of second housing grooves 122 are provided on the bottom wall of the first housing groove 121. The first housing groove 121 and the second housing groove 122 are connected to form a housing cavity 11. The covering portion is used to cover the housing portion 12 to seal the housing cavity 11 and prevent dust and lint from entering the housing cavity 11. Exemplarily, the covering portion may be a plate-like structure, which covers the housing portion to seal the housing cavity 11.

In addition, the omnidirectional coverage antenna device 20 is arranged in the accommodating cavity 11, and the omnidirectional coverage antenna device 20 is used to form an omnidirectional signal in the horizontal azimuth plane. The omnidirectional coverage antenna device 20 can be arranged in the first accommodating cavity 111 or the first accommodating groove 121 described above.

Among them, the omnidirectional coverage antenna device 20 can also be called an omnidirectional antenna, that is, it radiates uniformly in 360° in the horizontal direction diagram, which is usually called non-directivity, and it appears as a beam with a certain width in the vertical direction diagram. Generally, the smaller the lobe width, the greater the gain.

It can be understood that in order to prevent the omnidirectional coverage antenna device 20 from shaking in the first accommodating cavity 111 or the first accommodating groove 121 (in the accommodating cavity 11), in a possible structural design, the size of the first accommodating cavity 111 or the first accommodating groove 121 can be coordinated with the size of the omnidirectional coverage antenna device 20 to prevent the omnidirectional coverage antenna device 20 from shaking in the accommodating cavity 11.

In another possible structural design, the novel distributed base station 100 may further include: a first connector, which is used to fix the omnidirectional coverage antenna device 20 in the first accommodating cavity 11 or the first accommodating groove 121. Exemplarily, the first connector may be a screw, a hook, a buckle, a connecting glue, etc., which is not limited in the present application.

In addition, multiple log-periodic antenna devices 30 are all arranged in the accommodating cavity 11, wherein the multiple log-periodic antenna devices 30 can be arranged one-to-one in multiple second accommodating cavities 112, or the multiple log-periodic antenna devices 30 can also be arranged one-to-one in multiple second accommodating grooves 122.

The multiple log-periodic antenna devices 30 are all located on the same side of the omnidirectional coverage antenna device 20, the multiple log-periodic antenna devices 30 are arranged in a ring-shaped interval, and the polarization directions of the multiple log-periodic antenna devices 30 are all set outward, that is, the polarization directions of the multiple log-periodic antenna devices 30 are all set in a direction away from the first axis, and the first axis is the axis of the ring structure surrounded by the log-periodic antenna devices 30.

Similarly, in a possible structural design, the size of the second accommodating cavity 112 or the first accommodating cavity 121 may match the size of the log-periodic antenna device 30 to prevent the log-periodic antenna device 30 from shaking in the accommodating cavity 11 .

In another possible implementation, the novel distributed base station 100 may further include: a second connector, which is used to fix the log-periodic antenna device 30 in the second accommodating cavity 112 or the second accommodating groove 122. The second connector may also be a screw, a hook, a buckle, a connecting glue, etc., which is not limited in the present application.

The new distributed antenna in the present application includes: a housing 10, an omnidirectional coverage antenna device 20 and a plurality of log-periodic antenna devices 30. Among them, the new distributed base station 100 includes: a housing 10, an omnidirectional coverage antenna device 20 and a plurality of log-periodic antenna devices 30, wherein the omnidirectional coverage antenna device 20 is arranged in the accommodating cavity 11, and the omnidirectional coverage antenna device 20 is used to form an omnidirectional signal in the horizontal azimuth plane. Multiple log-periodic antenna devices 30 are all arranged in the accommodating cavity 11 and are located on the same side of the omnidirectional coverage antenna device 20; multiple log-periodic antenna devices 30 are arranged in a ring-shaped interval, and the polarization directions of the multiple log-periodic antenna devices 30 are all set outward. The new distributed base station 100 of the present application is used to establish a communication connection.

In this way, the new distributed base station 100 can form an omnidirectional signal in the horizontal azimuth plane through the omnidirectional coverage antenna device 20, and can cover the signal depth point through multiple logarithmic periodic antenna devices 30. In addition, the new distributed base station 100 can also use the deployment points of the original 4G indoor distribution system for effective reuse, thereby achieving the purpose of saving investment costs. The transmission and power supply equipment of the new distributed base station 100 can realize the rapid opening of the base station, thereby saving construction time and improving efficiency.

In some embodiments, multiple log-periodic antenna devices 30 are evenly distributed at annular intervals. In this way, the polarization directions of the multiple log-periodic antenna devices 30 are evenly distributed at annular intervals and face different directions, thereby ensuring that the surrounding positions of the new distributed base station 100 can achieve deep point coverage of the signal. In addition, it can avoid a certain position being located in the gain direction of multiple log-periodic antenna devices 30, resulting in a waste of resources.

In a possible implementation, the number of the log-periodic antenna devices 30 is 8, and any two log-periodic antenna devices 30 are arranged 45 degrees apart.

In this way, any two of the eight log-periodic antennas are arranged at a 45-degree interval. When it is necessary to locate an electronic device within the signal range of the new distributed base station 100, the coordinate position of the electronic device can be constructed through the eight log-periodic antennas, thereby facilitating the positioning of the electronic device.

In some other possible implementations, the number of the log-periodic antenna devices 30 may also be 12, 10, 6, 5, 4, or 3, etc., which is not limited in the present application.

In other embodiments, the multiple log-periodic antenna devices 30 can be selectively evenly distributed in the horizontal direction within a preset angle. In this way, if it is necessary to transmit the signal of the new distributed base station 100 in a direction toward a preset area, the multiple log-periodic antenna devices 30 can be selectively evenly distributed in the horizontal direction within a preset angle, and the polarization directions are all toward the preset area. In this way, it can be avoided that the signal of the new distributed base station 100 covers unnecessary areas (i.e., outside the preset area), resulting in a waste of resources.

In one possible implementation, the new distributed base station 100 also includes: an optoelectronic composite cable, which is electrically connected to both the omnidirectional coverage antenna device 20 and the log-periodic antenna device 30, and is used to establish power and communication connections with the omnidirectional coverage antenna device 20 and the log-periodic antenna device 30.

The optical-electric composite cable has optical fibers and copper conductors, wherein the optical fibers are used to transmit optical signals and the copper conductors are used to transmit power. The optical-electric composite cable has small outer diameter, light weight, and small space occupation (a series of problems that can usually be solved by multiple cables can be replaced by one composite cable here), and can provide multiple transmission technologies at the same time, has high adaptability to the same equipment, strong scalability, and wide product applicability.

Since the optical-electric composite cable integrates optical fiber and power transmission copper wire, it can solve the problems of broadband access, equipment power consumption and signal transmission. The new distributed base station 100 does not need to set up two lines (i.e., lines for transmitting power and establishing communication connections respectively), which is conducive to reducing the cost of base station construction.

In some embodiments, the omnidirectional coverage antenna device 20 includes: a first interface, which can be set on the side of the omnidirectional coverage antenna device 20 close to the log-periodic antenna device 30, and the first interface can also be set on the peripheral side of the forward coverage antenna device, which is not limited in the present application.

In addition, the plurality of log-periodic antenna devices 30 may each include a second interface 31, and the first interface and the plurality of second interfaces 31 are electrically connected to the optoelectronic composite cable. Thus, the signal received by the log-periodic antenna device 30 can be transmitted through the optoelectronic composite cable.

In this way, the optoelectronic composite cable can be electrically connected to the log-periodic antenna device 30 and the omnidirectional coverage antenna device 20 respectively, thereby avoiding the setting of a single optoelectronic composite cable electrically connected to both the log-periodic antenna device 30 and the omnidirectional coverage antenna device 20, which would cause network congestion.

In a possible implementation, the second interface 31 is disposed in the housing 10. As shown in Fig. 1, the second interface 31 is disposed on the side opposite to the polarization direction of the log-periodic antenna device 30. That is, the second interface 31 is located on the side wall of the log-periodic antenna device 30 facing the first axis direction.

Thus, the second interface 31 is disposed in the housing 10 and is located on the side opposite to the polarization direction of the log-periodic antenna device 30 . The second interfaces 31 of the plurality of log-periodic antenna devices 30 are close to each other, making it convenient to connect the optoelectronic composite cable to the plurality of second interfaces 31 .

In some embodiments, the optoelectronic composite cable may include: a first optoelectronic composite cable and a second optoelectronic composite cable, the first optoelectronic composite cable is electrically connected to the first interface, and is used to establish power and communication connections with the omnidirectional coverage antenna device; the second optoelectronic composite cable is electrically connected to the second interface 31, and is used to establish power and communication connections with the log-periodic antenna device 30.

Therefore, it is avoided that a single optoelectronic composite cable is provided to be electrically connected to both the periodic antenna device 30 and the omnidirectional coverage antenna device 20, which may lead to network congestion.

In a possible implementation, the log-periodic antenna device 30 further includes: a main interface, the second interfaces 31 of the plurality of log-periodic antenna devices 30 are all electrically connected to the main interface, and the main interface is electrically connected to the second optoelectronic composite cable.

In this way, the second optoelectronic composite cable only needs to be connected to the main interface to achieve electrical connection with the second interfaces 31 of the plurality of log-periodic antenna devices 30 , which is convenient for installation and use.

In a possible implementation, the omnidirectional coverage antenna device 20 and the log-periodic antenna device 30 both include: a radio frequency device 32,

The radio frequency device of the omnidirectional coverage antenna device 20 can support frequency bands such as 850M, 1800M, 2100M, 2600M or 4900M.

In a possible implementation, the log-periodic antenna device 30 may also support 850M, 1800M, 2100M, 2600M or 4900M frequency bands.

In another possible implementation, the log-periodic antenna device 30 can support other frequency bands supported by the radio frequency device of the omnidirectional coverage antenna device 20. In this way, the new distributed base station can support multiple frequency bands, thereby achieving coverage of more frequency bands for user convenience.

The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
