In order to estimate the signal parameters accurately for mobile systems, it is necessary to find a system's propagation characteristics through a medium. The path loss is one of such parameter which is associated with the design of base stations, as it tells them how much a transmitter needs to radiate to service a given region. Hence estimation of path loss becomes very important in initial deployment of wireless network and cell planning. An attempt has been made to estimate and analyze the path loss for GSM system. This paper starts with the path loss characterization of mobile communication channel using empirical Hata, LEE and COST231 model. These models are then compared with the measured data in rural and Semiurban non LOS environments.
