Mobile communication high-power distribution coverage system

Abstract

The invention discloses a mobile communication high-power distribution coverage system, which belongs to the technical field of mobile communication distribution coverage. The mobile communication high-power distribution coverage system comprises a core network transmitting end, a standard base station, a POI, a high-power distributor, a local side device, an optical line terminal and a service shunting device. The coverage effect is improved, passive devices with different coupling degrees are used to input appropriate power to the antenna to complete coverage, the overlay field intensity ismore uniform, the problems of excessive front-stage power waste and unavailable small rear-stage power when leakage cable coverage is adopted in the traditional scheme are avoided, therefore, the coverage range of a single POI system is expanded, POI point locations are greatly reduced, installation of installation point locations of active equipment and installation of power lines are reduced, the engineering construction difficulty is low, meanwhile, the property coordination difficulty is reduced, the engineering construction difficulty is reduced, and the system manufacturing cost and themaintenance difficulty are reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication distributed coverage, in particular to a mobile communication high-power distributed coverage system. Background technique [0002] The existing large-scale public building mobile communication distribution coverage project is generally jointly built and shared by multiple operators. After multiple base stations of different standards are combined through POI (multi-system combination platform), they are covered by power splitters and leaky cables. [0003] However, the traditional mobile communication distribution coverage scheme has the following problems: [0004] 1. In the traditional solution, due to the large POI loss, the coverage area is often limited; and when the leakage cable is used to cover the tunnel and other scenarios, due to the fixed loss of the leakage cable, the power of the front stage is large, resulting in a large waste of power. When the power is weak, the pow...

Problems solved by technology

However, in some indoor distributed coverage scenarios, the traffic density is not high, so it is hoped that the larger the coverage area of ​​a single base station, the better;

[0006] Therefore, how to solve the problems of high engineering cost, difficult engineering construction and difficult maintenance caused by the limited coverage distance of the base station in the above-mentioned traditional mobile communication distributed coverage scheme, and propose a more perfect large-scale mobile communication distributed coverage solution, has become top priority
