Ask everyone, what types of base stations are distributed base stations and macrocell indoor stations respectively, and what is the indoor distribution? ...

Mobile macro station: it is a kind of equipment used for cellular mobile phone communication. In the early stage of cellular mobile phone network construction, the coverage radius of cellular cell is relatively large, generally around 1 ~ 5km. The antennas of base stations in Hong Fengwo area are made as high as possible, and the distance between base stations is also very large.

Hong Jizhan is a device for cellular mobile phone communication. Distributed base station: it is a new generation of modern products used to complete network coverage.

Deep coverage: coverage of urban traffic-intensive areas, indoor coverage (as the signal source of indoor distribution system). Micro-base station Micro-base station can be regarded as a miniaturized base station, which concentrates all the equipment in a relatively small chassis and can be installed conveniently. Meanwhile, the micro base station can provide capacity like Hong Jizhan.

As shown in figure 10-27, the indoor distribution system is mainly composed of donor sources and signal distribution systems. Donor information sources are divided into Hong Jizhan, microcell, distributed base station and relay access repeater.
