Description

Novel distributed base station

Technical Field

The application relates to the technical field of communication, in particular to a novel distributed base station.

Background

In order to ensure a better coverage effect of the fifth generation mobile communication technology (5th generation mobile communication technology,5G) network, a huge amount of 5G distributed base stations need to be deployed indoors. The 5G distributed base station generally comprises: omni-directional antennas, which as their name implies radiate uniformly in the horizontal direction at 360 °, are commonly referred to as non-directional antennas, and log periodic antennas. The omni-directional antenna has a short coverage distance due to a low gain, and the investment waste is easily caused by large-scale laying.

Compared with an omnidirectional antenna, the log-periodic antenna has stronger gain effect and strongest penetrability, but the negative effects are obvious, besides the strong gain in the main lobe direction, the signal attenuation of the side lobe is obvious, so that the use scene is limited, the log-periodic antenna cannot be applied in a large scale, and the log-periodic antenna is only suitable for limited scenes such as elevators, underground parking lots and the like.

Therefore, how to ensure the coverage of multiple scenes of an indoor base station and also achieve the depth point coverage in a targeted manner is a technical problem to be solved.

In this way, the novel distributed base station can form an omnidirectional signal in a horizontal azimuth through the omnidirectional coverage antenna device, and can also cover a signal depth point through a plurality of log-periodic antenna devices. And the novel distributed base station can also effectively multiplex deployment points of the indoor distribution system by using the original fourth-generation mobile communication technology (the 4th generation mobile communication technology,4G), thereby achieving the purpose of saving investment cost. The novel distributed base station transmission and power supply equipment can be utilized to realize quick switching on of the base station, so that the construction period is saved, and the efficiency is improved.

In one possible implementation, the plurality of log periodic antenna devices are uniformly distributed in a circular interval. In this way, the polarization directions of the plurality of log-periodic antenna devices are annularly and uniformly oriented in different directions, so that the depth point coverage of signals can be realized at all surrounding positions of the novel distributed antenna. And moreover, the resource waste caused by the fact that a certain position is positioned in the gain direction of a plurality of log-periodic antennas can be avoided.

In one possible implementation, the number of log periodic antenna devices is 8. In such a way, 45-degree intervals are arranged between any two of the 8 log-periodic antennas, and when the electronic equipment located in the novel distributed base station signal range needs to be positioned, the coordinate position of the electronic equipment can be constructed through the 8 log-periodic antennas, so that the electronic equipment can be positioned conveniently.

In one possible implementation, the second interface is disposed within the housing and the second interface is disposed on a side of the log periodic antenna device opposite the direction of polarization. Therefore, the second interfaces are arranged in the shell and are positioned on one side of the log-periodic antenna device, which is opposite to the polarization direction, and the distances between the second interfaces of the log-periodic antennas are relatively short, so that the photosynthetic composite cable can be conveniently connected with the second interfaces.

With the high-speed development of information society, the living standard of people is improved, a 5G network is rapidly popularized, the 5G network is mainly characterized by larger network bandwidth, lower delay requirement and more network connection, and the 5G communication brings rapid increase of wireless traffic due to the characteristics of high working frequency band and large transmission bandwidth, but the deployment of the 5G network mainly adopts a traditional 4G networking mode, and the 5G frequency band is generally higher, so that the existing indoor distribution system is difficult to meet the 5G frequency requirement.

The construction thought of the traditional 5G network solves the coverage blind area by newly constructing a base station. But at present, the domestic 5G network generally operates in a higher frequency band (2.6 GHz or 4.9 GHz), so that the coverage of indoor signals needs to be realized by a special indoor base station. For traditional indoor scenes, indoor distributed base stations are generally adopted for coverage, and the current mainstream mode is to adopt optical fiber distributed indoor distributed base stations. Each device of the optical fiber distributed indoor branch base station is an antenna coverage point, so that a large number of distributed base stations are required to be deployed indoors in order to achieve a good coverage effect. The price of the 5G distributed base station is more than multiple times higher than that of the common antenna of the original 4G, and the power consumption is higher, so that the construction investment and the operation cost are greatly improved for operators and owners compared with the indoor distribution scheme of the 4G, and the scale and the progress of 5G indoor distribution construction are greatly hindered.

The current distributed base station mainly comprises: conventional omni-directional antennas, conventional indoor directional antennas, and log periodic antennas.

The deployment of traditional omni-directional antennas is still common in today's 5G network construction. Omni-directional antennas, as their name implies, radiate uniformly in the horizontal direction at 360 °, commonly referred to as non-directional antennas. The omni-directional antenna has a short coverage distance due to a low gain, and the investment waste is easily caused by large-scale laying.

The traditional indoor directional antenna is commonly called as a small-sized plate-shaped antenna, is mainly distributed in some areas needing deep coverage such as classrooms, movie theatres and the like, has far better penetrating effect than the traditional omni-directional antenna, and has smaller lobe direction angle and high gain. However, the defect of limited installation conditions still exists, the appearance is not hidden enough, the beautifying effect is not achieved, and the installation of the base station is difficult.

Compared with the two antennas, the log-periodic antenna has stronger gain effect and strongest penetrability, but the negative effects are obvious, besides the stronger gain in the main lobe direction, the signal attenuation of the side lobes is obvious, so that the use scene is limited, the log-periodic antenna cannot be applied in a large scale, and the log-periodic antenna is only suitable for limited scenes such as elevators, underground parking lots and the like.

Therefore, how to ensure the coverage of multiple scenes of an indoor base station and also achieve the depth point coverage in a targeted manner is a technical problem to be solved.

The application provides a novel distributed base station which is used for solving the problem that an indoor base station in the related technology cannot realize the surface coverage of signals at the same time and pertinently considers the depth point coverage.

In order to reduce the volume of the housing, in one possible implementation, the side wall of the housing surrounding the second accommodating cavity 112 may be arranged in a protruding manner, so that the space occupied by the housing 10 is small, which is beneficial for miniaturization of the novel distributed base station 100.

The cover part is used for covering the accommodating part 12 to seal the accommodating cavity 11 and prevent external dust and flock from entering the accommodating cavity 11. The covering portion may be, for example, a plate-like structure that is covered on the accommodating portion to seal the accommodating chamber 11.

In addition, the omni-directional coverage antenna device 20 is provided in the accommodation chamber 11, and the omni-directional coverage antenna device 20 is used for forming an omni-directional signal in a horizontal azimuth.

It will be appreciated that in order to avoid rocking of the omni-directional coverage antenna arrangement 20 in the first receiving cavity 111 or the first receiving groove 121 (within the receiving cavity 11), in one possible structural design, the dimensions of the first receiving cavity 111 or the first receiving groove 121 may be matched to the dimensions of the omni-directional coverage antenna arrangement 20 to avoid rocking of the omni-directional coverage antenna arrangement 20 within the receiving cavity 11.

In yet another possible structural design, the novel distributed base station 100 may further include: a first connection for fixing the omni-directional coverage antenna arrangement 20 in the first receiving cavity 11 or the first receiving groove 121. The first connecting piece may be a screw, a hook buckle, a connecting adhesive, or the like, which is not limited in the present application.

In addition, a plurality of log-periodic antenna devices 30 are disposed in the accommodating chamber 11, wherein the plurality of log-periodic antenna devices 30 may be disposed in the plurality of second accommodating chambers 112 in a one-to-one correspondence, or the plurality of log-periodic antenna devices 30 may be disposed in the plurality of second accommodating grooves 122 in a one-to-one correspondence.

The plurality of log-periodic antenna devices 30 are all located on the same side of the omni-directional coverage antenna device 20, the plurality of log-periodic antenna devices 30 are annularly arranged at intervals, and the polarization directions of the plurality of log-periodic antenna devices 30 are all arranged outwards, that is, the polarization directions of the plurality of log-periodic antenna devices 30 are all arranged far away from the first axis direction, and the first axis is the axis of the annular structure enclosed by the log-periodic antenna devices 30.

Similarly, in one possible design, the dimensions of the second receiving cavity 112 or the first receiving groove 121 may be matched to the dimensions of the log periodic antenna device 30 to avoid wobble of the log periodic antenna device 30 within the receiving cavity 11.

In another possible implementation, the novel distributed base station 100 may further include: and a second connection for fixing the log periodic antenna device 30 in the second receiving chamber 112 or the second receiving groove 122. The second connecting piece may be a screw, a hook buckle, a connecting adhesive, etc., which is not limited in the present application.

The novel distributed antenna in the application comprises: a housing 10, an omni-directional coverage antenna arrangement 20, and a plurality of log periodic antenna arrangements 30. Wherein, this novel distributed base station 100 includes: the omnidirectional coverage antenna apparatus 20 is arranged in the accommodating cavity 11, and the omnidirectional coverage antenna apparatus 20 is used for forming omnidirectional signals in a horizontal azimuth plane. The plurality of log periodic antenna devices 30 are all arranged in the accommodating cavity 11 and are positioned on the same side of the omni-directional coverage antenna device 20; the plurality of log-periodic antenna devices 30 are annularly arranged at intervals, and the polarization directions of the plurality of log-periodic antenna devices 30 are all arranged outwards, so that the novel distributed base station 100 is used for establishing communication connection.

In this way, the novel distributed base station 100 can realize the formation of an omnidirectional signal in the horizontal azimuth by the omnidirectional coverage antenna device 20, and can also realize the coverage at the signal depth point by the plurality of log-periodic antenna devices 30. In addition, the novel distributed base station 100 can also utilize the deployment point positions of the original 4G indoor distribution system to carry out effective multiplexing, thereby achieving the purpose of saving investment cost. The transmission and power supply equipment of the novel distributed base station 100 can be utilized to realize the quick turn-on of the base station, thereby saving the construction period and improving the efficiency.

In some embodiments, the plurality of log periodic antenna devices 30 are evenly distributed in a circular interval. In this way, the polarization directions of the plurality of log periodic antenna devices 30 are uniformly oriented in different directions at annular intervals, so that it is possible to ensure that the depth point coverage of the signal can be achieved at all the surrounding positions of the novel distributed base station 100. In addition, it is possible to avoid resource waste caused by a certain position being located in the gain direction of the plurality of log-periodic antenna devices 30.

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

In this way, the interval between any two of the 8 log-periodic antennas is 45 degrees, and when the electronic equipment located in the signal range of the novel distributed base station 100 needs to be located, the coordinate position of the electronic equipment can be constructed through the 8 log-periodic antennas, so that the electronic equipment can be located conveniently.

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

In other embodiments, the plurality of log-periodic antenna devices 30 are selectively and uniformly distributed at intervals within a predetermined angle in the horizontal direction, so that if the signal directivity of the novel distributed base station 100 needs to be transmitted towards the predetermined area, the plurality of log-periodic antenna devices 30 are selectively and uniformly distributed at intervals within the predetermined angle in the horizontal direction, and the polarization directions are all towards the predetermined area, so that the signal coverage of the novel distributed base station 100 to an unnecessary area (i.e. outside the predetermined area) can be avoided, resulting in the waste of resources.

Because the photoelectric composite cable integrates optical fibers and power transmission copper wires, the problems of broadband access, equipment power utilization and signal transmission can be solved. The novel distributed base station 100 does not need to provide two lines (i.e., lines for transmitting power and establishing communication connection, respectively), which is beneficial to reducing the construction cost of the base station.

In one possible implementation, the second interface 31 is disposed within the housing 10. As shown in fig. 1, the second interface 31 is provided on the opposite side of the log periodic antenna device 30 to the polarization direction. I.e. the second interface 31 is located on a side wall of the log periodic antenna device 30 facing the first axis direction.

In this way, the second interfaces 31 are disposed in the housing 10 and located on the opposite sides of the log-periodic antenna device 30, and the distances between the second interfaces 31 of the log-periodic antenna devices 30 are relatively close, so as to facilitate connection of the photoelectric composite cable with the second interfaces 31.

In some embodiments, the optical-electrical composite cable may include: the first photoelectric composite cable is electrically connected with the first interface and is used for establishing power and communication connection with the omnidirectional coverage antenna device; the second electrical composite cable is electrically connected to the second interface 31 for establishing electrical and communication connection with the log periodic antenna device 30.
