What is C-band radar used for?

C-band refers to the portion of the electromagnetic spectrum allotted for satellite transmissions in the 4GHz to 8GHz frequency range . C-band satellite antennas are used frequently in areas of the world where signals can become degraded due to heavy rain or other intense climate-related conditions.

C-band is all frequencies of the electromagnetic spectrum measured between 4 Ghz and 8 Ghz ; but the sweet spot of C-band that Verizon and AT&T are buying up is between 3.7 to 3.98GHz. That is used by satellite transmissions, wifi devices, and weather.

The C band is used for many satellite communications transmissions, some Wi-Fi devices, some cordless telephones as well as some surveillance and weather radar systems .

C band radars operate on a wavelength of 4-8 cm and a frequency of 4-8 GHz . Because of the wavelength and frequency, the dish size does not need to be very large. This makes C band radars affordable for TV stations.
