In network planning, radio propagation and coverage forecasting are both conducted on the basis of propagation models, while the classical models can not reflect the propagation characteristics of a particular environment accurately. Using these propagation models without calibrating may introduce serious errors into the predicted value.

在网络规划中，无线传播预测和覆盖预测都是基于传播模型进行的，而经典模型无法正确反映某个特定环境的电波传播特性，如果直接应用这些模型，预测值的误差可能很大。
