Relative surface of the WiMAX cell covered with modox of the signal

The first part of this paper gives a short introduction in WiMAX technology. Second part of the paper shows transmission modes in the WiMAX system 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 terrain and WiMAX system features, and is followed with conclusion at the end of this paper. Emphasis of this paper is in revealing propagation properties that shape relative surfaces covered with certain mode of signal in a WiMAX cell.
