Relative surface variation as a function of base station antenna heights at WiMAX Cell

This article gives calculation of the relative surface variation, for WiMAX cell, in percentage for covering particular modo of signal as a function of the WiMAX base station antenna heights. The first part of this paper gives a short description of WiMAX technology. Second part shows transmission modes in the WiMAX air interface, followed in the third part by mathematical approach for calculating the cell relative area covered with respective types of transmission modes. Fourth part of the paper presents simulations results that are obtained by using typical WiMAX system features. Emphasis of this paper is in revealing propagation properties that shape relative surfaces covered with certain mode of signal in a WiMAX cell.
