Outdoor 5G micro-station system based on broadcasting and TV HFC networkTechnical Field
The invention relates to the technical field of broadcasting and television HFC (hybrid fiber coaxial) networks, in particular to an outdoor 5G micro-station system based on a broadcasting and television HFC network.
Background
The HFC network consists of an optical fiber trunk line, a coaxial cable branch line and a user wiring network, and a program signal from a cable television station is firstly changed into an optical signal to be transmitted on the trunk line; after arriving at the user area, the optical signals are converted into electrical signals, distributed by the distributor and sent to the user end through the coaxial cable.
The main advantages of HFC networks are: the network signal transmission capacity is large, bidirectional transmission is easy to realize, the existing and emerging all transmission technologies are supported, and the signal transmission capacity is strong, so that the broadcasting and television HFC network structure can be continuously developed to provide network service for users.
At present, the frequency used by 4G network signals is below 2.7GMHz, and the 4G network signals have long-distance transmission capability, so that the 4G network has wide coverage capability in the aspect of network coverage, and therefore, the 4G network does not need to deploy dense micro base stations for network point supplement on the basis of 4G base stations. In the existing outdoor 5G base station stationing mode, because the 5G signals adopt signals with high frequency, the network transmission distance is short, the network signal attenuation is serious, and the 5G signals cannot be comprehensively covered in a long distance. If the problem needs to be solved, base stations need to be densely deployed for 5G signal compensation, but in cells with dense population buildings and office areas, sufficient space is not provided for building the base stations. And the deployment of the base station is also influenced by factors such as optical fiber and circuit laying, and the like, so that the requirement of multi-point deployment of the base station for comprehensive coverage of 5G signals cannot be met.
