Abstract :

The most advertised question these days is whether the use of a mobile causes cancer or not? As electromagnetic radiation intrigues the forms of ionizing and Non–ionizing in nature, many studies prove that exposure to ionizing radiation leads to increased risk of cancer. However, the studies resulted in no consistent evidence that non–ionizing radiation from radar, microwave ovens, and other sources causes no risk of cancer. The exposure to high levels of RF radiation can be harmful because Radio Frequency (RF) energy can heat the human body which is the principle followed by microwave ovens. Apart from cancer RF exposure has been a basis for many health threats like eye damage, skin burns, DNA changes due to thermal phenomenon of RF. If higher data rates need to be transmitted, the bandwidth required increases that obviously results in high RF exposure. As the modern mobile terminals that facilitate the applications like online gaming, web owsing, conference calling utilize much higher bandwidth for high data transactions, a communication system operating with reduced RF exposure is demanded. So, this paper aims to increase the system performance by restricting the RF exposure to its required limit without influencing the reception of desired high data rates using smart antenna deploying Constant Modulus Algorithm.
