Technical solutions to reduce exposure in mobile communication networks

Nowadays, due to different applications of cell phones and global approaches in the implementation of 5G networks, the level of public exposure to electromagnetic radiation has increased significantly. This increases concerns about the health effects of these exposures. Various methods such as power control, beamforming and massive MIMO are proposed to reduce the level of electromagnetic radiation in mobile networks. Furthermore, network topology and duration of exposure can be effective in reducing the level of exposure. In this paper, first, the definition of electromagnetic radiation, its criteria, effects and rules are mentioned. Then, the architecture of mobile communication networks and its effect on electromagnetic radiation are investigated. Afterwards, some technical solutions that can be used by network operator to reduce the level of electromagnetic radiation in the network are examined. Finally, some technical solutions are presented that can be used in cell phones to reduce the level of electromagnetic radiation of these devices.
