An indoor distribution system is a successful solution for improving the mobile communication environment in a building for indoor user groups. Because the wall-through loss of wireless communication signals is large, the base station signals cannot form effective full coverage indoors of the building body, and the phenomenon that indoor signals are poor or even partial positions have no signals is caused. The existing indoor distribution system is that antennas are distributed in floors, the antennas are connected with a base station through communication cables, and signals of a mobile communication base station are uniformly distributed at every indoor corner by using a related technical means, so that an indoor area is ensured to have ideal signal coverage.
Compared with 4G communication signals, the frequency of the 5G communication signals is higher, the signal bandwidth is larger, the space loss is larger, the penetration capability is poorer, and the effective coverage area of the outdoor base station is reduced. And the existing indoor distribution system can not meet the requirement of 5G, and the indoor distribution system is replaced or additionally arranged, so that the cost is high and the workload is large.
