Outdoor 5G micro-station system based on radio and television HFC network

Abstract

The invention discloses an outdoor 5G micro-station system based on a radio and television HFC network. 5G light machine device, the system is used for transmitting an HFC network and transmitting anHFC network signal. The signal input end of the 5G optical machine device is in signal connection with an HFC network metropolitan area network, wherein a wireless signal output end of the 5G opticalmachine equipment is in signal connection with a 5G mobile user side, the 5G optical machine equipment comprises a signal processing module and a 5G module, an uplink frequency point and a downlink frequency point of the signal processing module are in signal connection with the 5G module, and the 5G module sends a 5G signal to the 5G mobile user side. According to the invention, the 5G optical machine equipment of each outdoor node in the HFC network structure transmits the 5G signal, so that the coverage of the broadcast and TV outdoor 5G network can be realized quickly.

Description

technical field [0001] The invention relates to the field of radio and television HFC network technology, in particular to an outdoor 5G micro-station system based on the radio and television HFC network. Background technique [0002] The HFC network consists of three parts: optical fiber trunk line, coaxial cable branch line and user distribution network. The program signal from the cable TV station is first converted into an optical signal and transmitted on the trunk line; after reaching the user area, the optical signal is converted into an electrical signal, and distributed After distribution by the device, it is sent to the user end through a coaxial cable. [0003] The main advantages of the HFC network are: large network signal transmission capacity, easy to achieve two-way transmission, support for all existing and emerging transmission technologies, and strong signal transmission capabilities. Therefore, the HFC network structure of radio and television will contin...

Problems solved by technology

However, in the existing outdoor 5G base station layout mode, because 5G signals use high-frequency signals, the network transmission distance is short, and the network signal attenuation is serious, so it is impossible to fully cover 5G signals over long distances.

If this problem needs to be solved, base stations need to be densely deployed for 5G signal replenishment. However, there is not enough space to build base stations in densely populated residential areas and office areas.

Moreover, the deployment of base stations is also affected by factors such as optical fiber and line laying, which cannot meet the needs of multi-point deployment of base stations for full coverage of 5G signals.
