To protect ecological system from electromagnetic radiation of mobile communication

The ever-increasing use of mobile phones, IoT, and the related infrastructures like wireless access points and mobile base stations is becoming a prominent source of non-ionizing electromagnetic field (EMF) having some harmful effects on our ecology. In this work, the effect of the non-ionizing electromagnetic radiation of BTS (Base Transceiver Station) and the Wi-Fi access points on our ecological system has been investigated over frequency band 900 MHz to 2500 MHz. A testbed is designed utilizing sensors to measure the EMF strength over a given region, and a heat map is generated. Using the standard safe limit of specific absorption rate (SAR) this heat map may enable us to issue alerts whenever the measured EMF exceeds the SAR limit. The stream of data from these sensors may be uploaded on a cloud to implement an adaptive transmitter power control mechanism to reduce the signal strength dynamically to maintain the safe limit of SAR. A modular design is proposed to implement a cloud-based transmission power control mechanism that can be applied for BTS as well as Wi-Fi routers in cellular networks.
