C-band is a specific frequency range used in satellite communication that spans from approximately 4 to 8 gigahertz (GHz) in the electromagnetic spectrum. The “C” in C-band denotes “compromise” as it is considered a middle ground between lower and higher frequency bands.

Satellites equipped with C-band communication systems offer several advantages, making it a popular choice for a wide range of applications, including television and radio broadcasting, telecommunications, data transmission, and internet services. Its moderate frequency allows for a good compromise between atmospheric attenuation and data transmission capabilities.

One of the key strengths of C-band is its ability to resist rain attenuation effectively. This makes it highly suitable for regions experiencing heavy rainfall, as the signals transmitted in C-band can penetrate rain droplets with minimal signal loss. As a result, C-band is commonly used for television and radio broadcasting services, ensuring reliable and uninterrupted reception even during adverse weather conditions.
