A mobile communication base station refers to a radio transceiver station that transmits information between a mobile communication exchange center and a mobile phone terminal within a certain radio coverage area. The base station is applied for by the mobile communication operator to the radio management department for installation. It plays an important role in the GSM base station M network and directly affects the communication quality of the GSM network. GSM base station is a product with high technical requirements, and the initial base station equipment was mostly some foreign products. With the continuous deepening of some high-tech telecommunications companies in the field of mobile communication in China, some domestic telecommunications companies have also produced various models of base stations. The wireless networking characteristics endowed by GSM to base stations allow for a variety of implementation forms - macro cell, micro cell, micro cell, indoor and outdoor base stations. The limitations of wireless frequency resources also enable people to more fully develop different application forms of base stations to enhance coverage and receive traffic - remote TRX, distributed antenna system, fiber optic branching system, repeater
