This research work analyzes the non-incidence of solar flares on wireless communication systems operating in the microwave frequency band, specifically in the S band (2.4 GHz), such as WiFi networks. The study focuses on the influence of solar flares on the propagation of electromagnetic waves in the Very Low Frequency (VLF) band. A monitoring system was implemented that includes loop antennas, specialized VLF receivers, and microcontrollers to capture real-time data. This system allowed for the investigation of the relationship between solar events and the variability in VLF wave propagation, with relevant applications in submarine communications and navigation systems.The analysis covers the background of the problem, the research methodology, and the contribution to the knowledge of space weather. Additionally, the types of filters, reception systems, and antennas used are examined, highlighting their importance in accurately capturing data during solar events. The results of this research advance the understanding of the impacts of solar phenomena on electronic communications in the VLF band, providing valuable information to mitigate possible adverse effects.
