Sobre o Impacto de Eventos Solares no Desempenho da RAN de Sistemas 5G

In this article, we analyze the effects of solar radiation on mmWave (25-60 GHz) radio links, both in isolation and when integrated into the 5G mobile network. We found that variations in solar flux deteriorate the signal-to-noise ratio and increase path loss - an impact that tends to worsen in Brazil due to the South Atlantic Magnetic Anomaly. Through data interpolation and simulations, we identified interference patterns that compromise the reliability of the links, and these experiments provided estimates of the degree of degradation within the operating band and the extent to which the 5G network is affected.
