Zusammenfassung:The invention provides a base station frequency shift system which comprises a baseband unit, a 5G + 4G extended frequency shift unit and a frequency shift radio frequency unit, one end of the 5G + 4G extended frequency shift unit is connected with the baseband unit, and the other end of the 5G + 4G extended frequency shift unit is connected with the frequency shift radio frequency unit; the 5G + 4G extended frequency shift unit is provided with a first analog optical module, and the frequency shift radio frequency unit is provided with a second analog optical module. In the downlink, the 5G + 4G expansion frequency shift unit is used for transmitting the optical signal converted by the first analog optical module to the frequency shift radio frequency unit; and in the uplink, the frequency shift radio frequency unit is used for transmitting the optical signal converted by the second analog optical module to the 5G + 4G extended frequency shift unit. According to the base station frequency shift system provid
