Radio Frequency Electromagnetic Background in 5G Hot Spots

The declared increase in area traffic capacity of mobile communications to 107 bit/s/m2 in 5G systems and to 109 bit/s/m2 in 6G systems may cause an unacceptable increase in the level of electromagnetic background, especially in indoor hot spots, where the intensity of wireless public information services is maximum. A methodology for analyzing and assessing the average electromagnetic background levels in various configurations of the typical 5G scenario Indoor Hotspot-eMBB at frequency ranges FR1 and FR2 is proposed, indicating a significant contribution of subscriber terminal radiations to the average levels of the generated radio frequency electromagnetic background. The possibilities of safe implementation of this scenario for the population are ana­ lyzed, associated with the use of MIMO technology and base station antennas that provide adaptive formation of narrow beams in the direction of the subscriber terminals being served.
