The cellular networks always endeavoring continuously to provide high quality data for user's .This serves need high rate data coverage. Therefore interest has focused on increasing the coverage area to enhance the performance of networks. The aim of this paper is to investigate the using of reflectors to increase the coverage ratio of cell in the uncovered area (dead areas) resulted from the presence of high building .Research has been conducted in two methods, mathematical calculating and practical measurements which conducted in the laboratory by using electronic circuit with transmitter and receiver. The results obtained shows that by using the metal reflectors the signal quality can be increased. So the authors can say that this method is useful for increasing the coverage area of the cell.
