Radiation Safety Hazards of Cellular IoT Devices

The application of Cellular Internet of Things (CIoT) devices is rapidly increasing in many use cases such as healthcare and smart cities. Governments, enterprises and even start-ups are heavily investing in implementing new solutions using cellular IoT technologies. However, there are many concerns associated with the deployment of these technologies that lead people to be hesitant in welcoming CIoT solutions. Security, privacy and safety issues are among these concerns. Consumers of IoT wearable devices are worried about the negative effects that the radiation of smart devices may have on their health. In this article, we address the safety concern by reviewing the standard limits of human exposure to radio frequency electromagnetic energy and analyzing the radiation levels of CIoT antennas.
