EM Radiation Reduction in WCN: Towards Safe Generations

With the 5G wireless communication network (WCN) on its way of standardization, the 5G New Radio (NR) interface standard is also under development with new technologies and higher potentials. This has also initiated the exploration of mmWave frequencies to expand the range of the spectrum. As we are moving towards a high range of frequencies, it is also leading to increased levels of RF wave exposure in the environment. The high EM radiation exposure has become an area of concern for the future generation of networks to come. Electromagnetic radiation is measured in terms of metrics such as power density, temperature elevation, high Specific Absorption Rate (SAR) levels in the human body tissues causing an adverse effect on the health. In this article, the same issue has been addressed along with a discussion of some radiation reduction techniques and a proposal to minimize EM radiation in mobile communication systems in the form of “Radiation Reduction (RR)” mode. The radiation reduction effect can be further reduced by incorporating NOMA (Non-Orthogonal Multiple Access). It is the need of the hour to reformulate the regulations and guidelines to ensure safety and reliability for the future generation of networks.
