Embodiment 1

[0038] Such as Figures 1 to 3 As shown, the present invention provides a closed-space distributed large-capacity wireless broadband networking system, including a control station, a switch, several base stations and leaky coaxial cables;

[0039] The console is connected to the switch through Ethernet, the switch is connected to several base stations through coaxial cables, and several base stations are connected to the leaky coaxial cables, and the leaky coaxial cables are connected along the The trajectories are laid around such that each of the base stations covers a set of moving nodes.

[0040] Specific as figure 2 As shown, the leaky coaxial cable includes an inner conductor 1, an insulating medium layer 2, an outer conductor 3 and an outer sheath layer 5 arranged sequentially from the inside to the outside, and the surface of the outer conductor is provided with a number of penetrating holes according to preset intervals. Slot 4.

[0041] In a specific application,...

Embodiment 2

[0043] Since the electromagnetic wave is transmitted longitudinally in the leaky cable, it radiates to the outside through the slot; the external electromagnetic field can also be induced into the inside of the leaky cable through the slot and transmitted to the receiving end. Leaky cables have dual functions of feeder transmission and receiving and transmitting antennas.

[0044] Therefore, the difference between this embodiment and Embodiment 1 is mainly that a receiving end is added to the system to realize two-way data transmission between the console and the receiving end.

[0045] Specifically, the closed-space space distributed large-capacity wireless broadband networking system of Embodiment 2 includes a control station, a switch, several base stations, leaky coaxial cables, and a receiving end arranged in a moving node area;

[0046] The console is connected to the switch through Ethernet, the switch is connected to several base stations through coaxial cables, and se...

Embodiment 3

[0049] Although, the advantage of the leaky coaxial cable system is that it can ensure continuous and uniform coverage of the signal, and a reasonable selection of leaky cable types can support broadband multi-system coverage. However, the main disadvantages of leaky coaxial cables are small coverage and high loss; the coverage is within 10 meters, and power amplifiers can be added to the base station when the loss problem needs to be considered.

[0050] Therefore, the difference between the present embodiment and the second embodiment is mainly that a power amplifier is provided on the base station or the leaky coaxial cable to obtain larger applicable scenarios.

[0051] Specifically, the closed-space space distributed large-capacity wireless broadband networking system of Embodiment 2 includes a control station, a switch, several base stations, leaky coaxial cables, and a receiving end arranged in a moving node area;

[0052] The console is connected to the switch through ...

Description

technical field [0001] The invention relates to the technical field of wireless communication transmission, in particular to a closed-space distributed large-capacity wireless broadband networking system and a networking method. Background technique [0002] When the working environment of traditional base station antennas is a metal-enclosed space and there are a large number of metal supports, it will cause signal occlusion, reflection, scattering and other phenomena, which will affect the transmission of wireless signals. Therefore, traditional base station antennas cannot form effective and reliable coverage. There are two main difficulties in confined space wireless networking technology: first, how to achieve good coverage of wireless signals in an environment with a large number of metal frames; second, how to achieve large-capacity, high-speed and reliable data transmission. Design the air interface based on leaky cable for the first problem; design the physical laye...
