Approximation conditions

Frequency: 150MHz - 1500MHz

Communication range: 1Km - 20Km

Base station antenna height: 30m - 200m

Mobile station antenna height: 1m - 10m
 

Approximation

Here A and B are the same for each area.  a(hm) and C have different values for each area.
Furthermore, in large cities, the a(hm) value differs according to whether the working frequency is above or below 400 MHz.

Parameters
