Abstract
Learning and teaching the course of Mobile Communications Systems for several semester caught the attention of the author of this article to one thing, namely the inconsistency between the given propagation equation (such as OkumuraHata) and the completely usage of all components in the equation, when doing the planning of cellular coverage or calculating the path loss.There is a component in the equation which is writtenbut sometimes does not used in the examples of problems solution. The component is the Mobile Station antenna height factor, symbolized by a (hm), where a as a function of hm and hm itself is a mobile station antenna height. Then the question is whether the effect of Mobile Station antenna height factor to the path loss could be ignored? or when it should be including the factor of a(hm) and when it should not be including. Here, this problems is then verified through a method of simulation using Matlab. The result shows the pathloss of 2 compared models, where the 2 models were differensiated by using or does not using Mobile Station antenna height factor. The conclusion is, the very least value of pathloss difference between 2 compared models occurs when the Mobile Station antenna height is 1.5 meters. It means that when the assumption of Mobile Station antenna height is 1.5 meters, then it is not important to include a(hm) factor because its effect to the pathloss is very insignificant, where the different mean value is0,0024%.
