A base station, i.e., a common mobile communication base station, is a form of a radio station, which refers to a radio transceiver station for information transfer with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. The construction of mobile communication base stations is an important part of the investment of mobile communication operators in China, and the construction of the mobile communication base stations is generally carried out around the factors of coverage, call quality, investment benefit, difficult construction, convenient maintenance and the like. With the development of mobile communication network services toward datamation and packetization, the development trend of mobile communication base stations is also inevitably to make the mobile communication base stations broadband, large coverage area construction and IP.
The selection of a base station needs to be considered comprehensively from the aspects of performance, matching, compatibility, use requirements and the like, wherein especially, the base station equipment needs to be compatible or matched with a mobile switching center so as to obtain a better communication effect. The base station subsystem mainly comprises two types of equipment: a Base Transceiver Station (BTS) and a Base Station Controller (BSC).
Large homes often see high-rise antennas on the roof, which are part of the base transceiver station. A complete base transceiver station includes radio transmitting/receiving equipment, antennas and signal processing parts specific to all radio interfaces. The base transceiver station may be considered as a radio modem responsible for the reception and transmission of mobile signals. Generally, in a certain area, a plurality of sub-base stations and transceiver stations mutually form a cellular network, and the transmission of mobile communication signals is achieved by controlling the mutual transmission and reception of signals between the transceiver stations and transceiver stations, and the area in the area is the network coverage which we often say. If the transceiver station is not available, the transmission and the reception of the mobile phone signals cannot be completed. The area that the base transceiver station can not cover is also the blind area of the mobile phone signal. The range over which the base transceiver station transmits and receives signals is directly related to the quality of the network signals and whether the handset can be used normally in the area.
At present, the antenna of the communication base station is mostly fixed and immovable, the height of the antenna cannot be raised or lowered, the height of the fixed block cannot be changed along with the change of the wind speed, and the antenna is easy to bend when the wind speed is too large.
