description The present invention discloses a method for calibrating intelligent antenna. When a baseband pool unit (BBU) receives a request for establishing a cell carrier on a remote radiofrequency unit (RRU), the following steps are executed: A. determining whether the RRU is executed with initialization calibration, if the RRU is not executed with the initialization calibration, continuing for executing the step B, otherwise continuing for executing step C; B. executing initialization calibration to the RRU; C. establishing a corresponding cell carrier on the RRU according to the request for establishing cell carrier; and D. after the cell carrier is successfully established, executing a first periodic calibration to the corresponding cell carrier channel, and executing periodic calibration to the cell carrier channel according to the collocated calibrating period. The application of the invention can trigger the initialization calibration and periodic calibration in time for guaranteeing theservice quality of wirele
