I. Introduction
Today's context the wireless technology becomes more and more popular in cellular network. Broadband wireless system has potential success in LOS (line-of-sight) and non line-of-sight(NLOS) in different frequencies. In radio communication system the path loss is the important element in wireless network. The elements of the radio communication systems are transmitter power, antenna height and antenna gain. Also, we have to understand clearly the radio path loss is the relation between coverage area and level of signal loss in a particular environment. Thus the radio propagation model plays a important role in optimizing network performance. The analyses of radio propagation on different environments like urban, suburban terrains and rural considered in this paper [7]. The terrains are highly imperative on different obstructions like high buildings, towers, shadowing effect, hilly stations etc. These obstructions are completely beyond the control of site engineers. The optimized network planning can be done on the theories of physics and mathematics applied, so we focused on this area [8].
