Distributed underground pico base station system based on centralized power supply

Abstract

The invention discloses a distributed underground pico base station system based on centralized power supply. The system comprises a distributed 5G pico base station subsystem and a centralized DC far-end power supply subsystem. The distributed 5G pico base station subsystem is composed of a local side main equipment baseband unit module, a concentrator unit module and a radio frequency far-end unit module. And the centralized direct-current far-end power supply subsystem is a centralized direct-current far-end power supply module. And the main equipment baseband unit module is connected with the radio frequency far-end unit module through the concentrator unit module. A specified number of master device baseband unit modules are deployed in a 5G communication network area, one master device baseband unit module can be connected with a plurality of concentrator unit modules, and one concentrator unit module can be connected with a plurality of radio frequency far-end unit modules. And a communication task between the main equipment baseband unit module and the radio frequency far-end unit module is completed through the concentrator unit module. According to the invention, the signal coverage range of the remote underground pico base station is enlarged, and the cost of building a 5G communication network is reduced.

Description

technical field [0001] The invention belongs to the technical field of 5G micro base stations, and in particular relates to a distributed underground base station system based on centralized power supply. Background technique [0002] With the country's vigorous construction of 5G networks in recent years, the scale of base stations and the number of users have shown a trend of rapid growth. Due to the rapid development of the economy and the acceleration of urban construction, the buildings are getting taller and denser, and most of the buildings are made of reinforced concrete, plus the fully enclosed exterior decoration, so that the transmission of 5G signals is blocked. , causing some original good coverage areas to become weak coverage areas and blind areas. Especially for scenarios where coordination is difficult and implementation is difficult, such as underground tunnels and underground shopping malls, the construction of 5G signal base stations and the transmission...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the underground construction mode of communication facilities in the existing technology cannot be fully and effectively applied to the deployment of 5G communication networks in underground environments, and signal coverage must be provided through a distributed, small-antenna base station construction mode
