Effects of Mobile Radiations and its Prevention

The number of mobile users is increasing as the time passes and the technology keeps on evolving to meet the requirement of higher data rates than the previous generation. This in turns leaves a huge harmful biological impact on the biodiversity. The microwave mobile communication systems include the TV, FM and AM broadcasting station which use large amount of power to transmit the signals at a greater amount of distance. WiFi and WiMAX are used in most of the developed parts of the world where there is a need of greater data rates. Both of these communication technologies have operating frequencies of some multiples of GHz which is the higher end of the microwave frequency band. The microwave frequencies used in the cellular communication causes the thermal and non-thermal effects. There is a lot of damages that is done by the non-thermal effects as compared to the thermal effects. The electromagnetic radiations are also recognized as the major cause of cancer. The EMR emitted by the mobile antennas used at the base stations effects the cell structure of the living beings. Also the mobile devices used by users have a rating of specific absorption rate (SAR), it is a measure of the power that a human body absorbs using the mobile device which should be safe radiation level absorbed by the human. All the above broadcasting and communication technologies have brought the revolutionary change in the wireless system and are also responsible for the most of the devastating effects on the living beings. This paper discusses various problems caused by the wireless communication technologies and expected methods to reduce the effects. There are international exposure limits and guidelines for radio frequency fields. There is need of an hour to understand health problems from radio frequency radiations and implementation of the guidelines.
