Декларируемое увеличение территориальной плотности трафика мобильной связи до 107 бит/с/м2 в сетях 5G и до 109 бит/с/м2 в сетях 6G может быть причиной недопустимого роста уровня электромагнитного фона, особенно в хот-спотах внутри помещений, где интенсивность беспроводного информационного обслуживания населения максимальна. Предложена методика анализа и выполнены оценки средних уровней электромагнитного фона в различных конфигурациях типового сценария Indoor Hotspot-eMBB 5G диапазонов частот FR1 и FR2, свидетельствующие о существенном вкладе излучений абонентских терминалов в средние уровни создаваемого радиочастотного электромагнитного фона. Проанализированы возможности безопасной для населения реализации этого сценария, связанные с использованием технологии MIMO и антенн базовых станций, обеспечивающих адаптивное формирование узких лучей в направлении на обслуживаемые абонентские терминалы.

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.
