In the traditional GSM network planning, the revised Hata model serves as the prototype, and the coefficient in the model formula is tuned according to the data obtained in the radio propagation feature test specific to local actual radio environment, so as to obtain the propagation model for practical prediction. A common digital map only contains the clutter information and the digital terrain model information. So the building designers cannot fully allow for the influence of radio propagation, and can only estimate the influence on the building roughly from a traditional perspective, e.g., consider the influence of different clutters through certain clutter offset.
