Abstract

Radio covered area of a base station is called cell. These are served by at least one fixed-location transceiver, known as a cell site or base station. In a radio network, different set of frequencies are used by each cell from their neighboring cells to avoid clash and serve guaranteed bandwidth within each cell. Interference can be minimized by maintaining a certain distance between cells that uses the same frequencies. Hence, this distance can be shortened without disturbing the cell reuse pattern. As the sizes of the cells are reduced, the identical frequencies can be used in various cells, which in turn mean more subscribers can be accommodated on the system. In our proposed work we use the concept of sectoring. Using sectoring a cells area is decreased depending on the type of sectoring used. As area of the cell gets reduced the power needed to cover the area also gets reduced and with transmitter antenna’s power gets reduces so as the reuse distance of cell. So reuse distance is proportional to transmitter power of the Base station’s antenna.
