Description
Since the emergence of 5G technologies, questions remain regarding a possible increase of the electromagnetic fields - EMF, to some extent due to the use of reflections to reach out of sight users.
Thanks to numerical simulations, a comparison between 4G conventional and 5G adaptive antennas is performed. Realistic adaptive beams are first created by using Uniform Planar Array methodology. The resulting EMF are then obtained through ray-tracing calculations.
Our current results show that only one to three reflections must be taken into account when studying EMF, and this regardless of the building material properties and of the antenna types. Beyond four reflections, the contribution to the total EMF is likely to be neglected.
Furthermore, compared to conventional systems, adaptive antennas provide better quality of service and connectivity for out of sight users, while enabling lower EMF emissions in areas without data traffic.
