Abstract: The cellular mobile communication industry has recently been one of the fastest growing industries. Need for high quality and high capacity networks, estimating coverage accurately has become extremely important. The generic RF propagation prediction algorithms based on empirical results give only approximate coverage, and are not suitable for detailed network design. Therefore for more accurate design coverage of modern cellular networks, signal strength measurements must be taken in the service area using a test transmitter. Measuring signal strength is an expensive and a time consuming task. It is known that the accuracy of coverage estimation increases with the distance of the signal strength measurement drive route. Propagation path loss model is the fundamental method of predicting the range of a mobile system. The accuracy of the path loss predictions is a crucial point to determine whether a particular system design will be viable. Therefore, this paper presents how a variety of possible methods exist that allow the engineer to predict the path loss with sufficient speed and accuracy and it is vital that a prediction method that engineers are confident in is adopted before the network designed. This paper also addresses the comparisons between the theoretical propagation model, empirical propagation model and the practical measurement.
