Wireless network propagation model is a prediction model of radio propagation characteristics.prediction of propagation characteristics is the fundament of wireless network planning

its accuracy affects the accurate and quality of network planning.this theses discusses the low efficiency and low accuracy of the CW test for propagation model calibration

put forward a kind of new propagation model calibration way by using drive test data

proof theory that drive test data can be used in propagation model calibration insteads of CW test data.The paper uses SPM model for propagation model calibration.
