摘要：Indian Telecom Market is witnessing Data Boom. More and more people are shifting towards Wireless Communication.Due to this , service providers are concentrating on it to generate better revenue.Wireless broadband is going to be a force to reckon with. The cellular mobile technology will be big contributor for wireless broadband due to emergence of Third Generation (3G)and Fourth Generation(4G) mobile technology. It is the fundamental task to predict the coverage of the proposed mobile system. Coverage in a cell depends upon the area covered by the signal. Radio propagation characterstic determine the extent to which a signal can travel in given area. The signal strength estimation using propagation models is dealt in this paper . Radio propagation varies from region to region . A wide variety of approaches have been developed over the years to predict coverage using propagation models. Propagation models are useful for predicting signal attenuation or path loss which may be used as a controlling factor for system performance or coverage so as to achieve perfect reception. The various path loss models like Free Path Loss , Hata, Okumara , COST 231 Hata and ECC 33 models are analyzed and compared. The received signal strength is calculated with respect to distance to determine the model that can be adopted to minimize the number of hand offs .EDX Signal Software is used for simulation purpose. The received signal strength depends on the path loss and the parameters of the transmitter and receiver . Quality of call establishment is based on received signal strength. Signal strength varies based on the environment and the intermediate losses.
