The methods of forecasting of wireless electric wave propagation can divide into two parts: one is pluse and respond, that is establish the empirical model based on experimental and statistical data;
无线电波传播预测的方法分为两类:一是用冲激响应法,即根据实验、统计所得数据建立经验性传播预测模型;
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。
