FSO links operate at a much higher frequency than RF links, generally at near-infrared bands (e.g., 1064 nm or 1550 nm). Visible light is often not used due to eye safety
Space weather impacts radio communication in a number of ways. At frequencies in the 1 to 30 mega Hertz range (known as "High Frequency" or HF radio), the changes in ionospheric

Ionospheric storms can affect High Frequency (HF) radio communication at all latitudes. Some radio frequencies are absorbed and others are reflected, leading to rapidly

When solar activity is high, both critical frequency and MUF rise, so you can use higher HF bands. If solar activity is low or there''s a disturbance, those numbers drop, and you

Solar conditions play a pivotal role in ham radio propagation, particularly for high-frequency (HF) communications. The Sun's activity, influenced by the solar cycle, impacts the ionosphere —the atmospheric region that refracts radio waves back to Earth, enabling long-distance communication.
However, Solar flares and coronal mass ejections (CMEs) can cause increased radio noise and potential disruptions. Conversely, during solar minimum, reduced solar activity results in lower ionization levels, which can limit HF propagation and reduce communication range.
The "sun-outage" effect can be significantly increased during periods of high solar radio burst activity. Satellite communications using lower frequencies (VHF through L-band) can experience significant short term signal losses (dropouts) due to ionospheric scintillations.
During periods of high solar activity, such as solar maximum, the increased number of sunspots enhances the ionosphere's ionization. This higher ionization significantly improves HF signal propagation, allowing ham radio operators to achieve greater distances.
