Factors effecting the Accuracy of Prediction

The standard deviation is constant along a path loss curve. The path-loss slope is 40dB/dec in case of both line-of-sight path and out-of-sight path. However, the direct path and reflected path in case of line-ofsight path are strong and in out-of-sight path is weak. By media ting these two conditions, 1-mi intercept is obtained, which is strong in open area but weak in urban areas.

The standard deviation obtained from the predicted path-loss curve is almost equal to S dB and is constant throughout the radio path. But the received signals vary based on the type of path. i.e. for line-of-sight path the received signal is strong for partial line-of-sight path it is norm al and for out-of-sight path the received signal is weak. These are few factors, which affect the accuracy of the prediction.
