While 5G brings revolutionary service experiences and new business application models, it also puts forward diversified new requirements for bearer networks, especially indoor bearer networks. According to industry research reports, nearly 80% of services in 4G networks take place indoors. With the continuous increase of 5G service types and the continuous expansion of industry boundaries, the industry predicts that more mobile services will take place indoors in the future, but currently 50% of users are not satisfied with the 4G indoor mobile communication coverage experience. Therefore, the indoor coverage of 5G networks Overlay deployment becomes more important

[0003] At present, indoor coverage solutions are mainly divided into three categories. The first category is outdoor macro base station penetration coverage indoors. In the 2G / 3G / 4G era, outdoor macro base station penetration coverage is the main way to solve indoor signal coverage. However, with With the continuous improvement of the working frequency band of the 5G system, the outdoor macro base station signal can only provide shallow indoor coverage after penetrating obstacles such as brick walls, glass, and cement, and cannot guarantee the good experience required for deep indoor coverage.

[0004] The second type of solution is to use the traditional passive indoor distribution system to evenly distribute the signal of the mobile base station in every corner of the room through the indoor antenna distribution system, so as to ensure that the indoor area has ideal signal coverage. However, the supporting passive indoor distribution system The transmission capacity of the feeder is limited by traditional components, and the insertion loss and other indicators are difficult to meet 5G applications

[0005] The third type of solution is to build 5G indoor small base stations. 5G indoor small base stations are miniaturized, low-power base station equipment that are deployed indoors to solve the problem of indoor deep coverage. However, the bearer capacity of 5G indoor small base stations to outdoor aggregation nodes The transmission problem is a new challenge. It is technically feasible to use optical fiber to carry 5G indoor small base stations, but there are many problems in the actual deployment process. Families that implement fiber-optic access only deploy optical fiber to the weak current box, and each bedroom has no optical fiber interface. To solve the above problems, it is necessary to re-expand the expansion of the corridor pipeline and the construction of the home, which is very difficult and costly
