What are the main practical applications of the 4.2–4.6 GHz portion of the C-band?

I frequently encounter the 4.2–4.6 GHz band in antenna and RF design specifications.
While it is labeled as C-band, its exact applications seem to vary across domains.
I want to clarify which industries and systems predominantly rely on this frequency range and why it remains relevant.

From my experience, the 4.2–4.6 GHz range is most strongly associated with satellite downlink and radar applications. I have seen it widely used in C-band satellite earth stations because it offers a good balance between bandwidth availability and resistance to rain fade. I would also point out its importance in weather and maritime radar, where reliable propagation matters more than compact antennas. In recent years, I have seen growing interest in this band for fixed wireless and private networks, especially where lower microwave frequencies are congested.
