In mobile communication, the transmission path from transmitter to receiver may be line of sight or may be obstructed by buildings, trees and mountains. The signal is received from multi path varies randomly with respect to time, frequency and distance from transmitter. Mobile video transceivers, which can transmit audio-visual messages, while on move, have got number of vital applications. To design a mobile transceiver, estimation of path loss is essential. There are number of propagation models to predict the path loss (Behera & Das, 2008). However, there is a large variation in the path loss predicted using these models. These models are basically based on the data collected in parts of the globe other than India. To find out the path loss slope applicable for Indian suburban areas, the received signal strength is measured at various distances from the transmitter. For this, radiations from existing cellular mobile communication transmitters (base Stations) are used. The received signal strengths are then analysed and path loss slope is worked out. This path loss slope can be used to design mobile transceivers to be used in India and countries with similar environmental conditions.
