It discloses a method for obtaining and apparatus types received signal strength indication. According to analysis, the signal independent of the attenuation of the signal content antenna transmission to the analog receiver process, but rather to the reception frequency, thereby obtaining a first compensation value related to the attenuation from the received frequency, while, in the analog receiver process of signal amplification, the different automatic gain control coefficient corresponding to the gain errors, the error is independent of the signal content, but is associated with an automatic gain control factor, thereby obtaining automatic gain control coefficient associated with the error a second compensation value to compensate for the attenuator and the error by the second compensation value and the second compensation value, thereby improving the acquisition accuracy of the RSSI.
