Abstract: The exponential growth in energy utilization & consumption in cellular network by the user devices and by telecom equipment has imposed critical problemsbecause of adaptation of high range frequency in available spectrum (Ultra High Frequency-UHF) by government and technology.The other reason for more power consumption is extensive applications of mobile data services to video streaming, surveillance, internet surfing and healthcare monitoring.Other important causes of energy consumption which has been recognized are power-hungry processors, poor design of power amplifiers etc. Presence of different species of foliage in hilly area increases signal attenuation, consequently in order to maintain the threshold value of signal, the power is increased. The recent researches predict that the data traffic is being increased by several-fold every year. Under such predictions, energy expenditure at its control is a major challenging task for telecom companies and for research communities. This paper studies the actual signal intensity drop because of irregular nature of terrestrial pattern and foliage in Illuba Bore zone, from theoretical perspective as well as practical point of view.

I. INTRODUCTION
The presence of high densities of long trees with different species acts as reflectors and scatters for electromagnetic (EM) wave. Consequently, it increases the path loss in between transmitter and receiver. The exact estimation of the attenuation and degradation of ultra-high frequency signal(UHF) due to trees are rather complex because there are so many variables like height of tree, shape, density, season and humidity are involved in cause of attenuation. In urban or sub urban areas, where there is a small concentration of trees, the effect is negligible.
