Okumura - Hata curve



<Formula>

 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

<Common to all areas>



<Open land>



<Suburbs>



<Medium city>



<Large city>




*Please use the results of the calculation as a reference value.
