Effect of Radio Frequency from Cellular System on Human Body & Its Potential Remedy Li-Fi for Next Generation Wireless Network

Pragati Sharma, A. K. Gautam

Abstract

There is a huge body of evidence in the literature that exposure to radio frequency (RF) has been linked to a variety of adverse health outcomes that may have significant health problems for user of mobile phone. Credible scientific evidences are there that RF radiation from cellular system is responsible to create effect that may be either short term (sleep disruption, lack of concentration, behavioral changes etc) or  long term (DNA damage, altered immune function, miscarriage risks, etc.). Cellular region of frequency spectrum covers a vital range of frequency worldwide. It uses Base Transceiver Stations (BTS) and Mobile Station (MS) for its operation therefore the emission of energy from BTS and MS is quite dangerous and needs everyone attention. In second generation systems, BTS works on frequency reuse concept and after few kilometers, we found another BTS to serve the mobile phone. BTS power gets reduced as the distance from BTS to MS increases. At such condition, mobile starts to emit more power to maintain the link and sometimes switches to another nearby  BTS area. A new emerging technology, Light- Fidelity (Li-Fi) is in consideration for future use of communication because it is capable to work safe against health hazards. It can be understood as a carrier to transmit data wirelessly in spite of using radio waves. 

In this paper, we tried to check the effects of radio frequency at various conditions. These conditions are studied carefully and a comparative analysis is done (based on available literature) to aware mankind regarding harmful effects of radiation from cellular system on human body and also focus on its proposed remedy to overcome the hazardous effects of electromagnetic radiation.
