摘要

移动电话、物联网以及无线接入点和移动基站等相关基础设施的使用日益增加，正成为非电离电磁场(EMF)的主要来源，对我们的生态产生了一些有害影响。在这项工作中，研究了900 MHz至2500 MHz频段上BTS (Base Transceiver Station)和Wi-Fi接入点的非电离电磁辐射对我们生态系统的影响。设计了一个试验台，利用传感器测量给定区域的电动势强度，并生成热图。使用特定吸收率(SAR)的标准安全限值，该热图可使我们在测量的EMF超过SAR限值时发出警报。这些传感器的数据流可以上传到云端，实现自适应的发射功率控制机制，动态降低信号强度，以保持SAR的安全极限。提出了一种模块化设计，实现基于云的发射功率控制机制，可应用于蜂窝网络中的BTS和Wi-Fi路由器。

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.
