Our environment is subjected to exposure to microwave and radio electromagnetic irradiations because of widespread use of wireless telecommunication services. The electromagnetic radiations like radio waves, microwaves and Infrared rays emitted from the multiple telecom sites also contributing large amounts of environment harming to natural eco systems and causing climate change. A potentially constant exposure has caused an alert in public and governments about the so-called environmental electromagnetic pollution. Assessment of the RF EMF impact on plants is of great importance because plants have an important role in the living world as main primary producers of organic compounds and oxygen. Plants are continuously exposed to various environmental stresses and display a wide spectrum of developmental and biochemical responses contributing to stress adaptation. Their physiological responses can be evoked by a great variety of external stimuli, including mobile phone radiation. The adverse effects of electromagnetic radiation from mobile phones and communication towers on health of human beings are well documented today. However, exact correlation between radiation of communication towers and eco-system, are not yet very well established. In this context, there is need to carry out the scientific investigations to understand the effects of RF radiation on plants. The main objective of this research is to measurement of signal strength and power emitted by the tower and to establish guidelines for limiting EMF exposure that will provide protection against blown adverse effects on ecosystems will be studied using Geo-Informatics techniques in Udupi District, Karnataka State. The advancement in the recent years in the field of Geo-Informatics has enabled us to get the required spatial information of the environment in a better way. [ABSTRACT FROM AUTHOR]
