The document summarizes three common frequency bands used in satellite communication: C-band, Ku-band, and Ka-band. C-band uses frequencies between 3.7 to 6.425 GHz and is used by many commercial satellites. Ku-band uses frequencies between 11.7 to 14.5 GHz and is primarily used for satellite communications and television broadcasting from remote locations. Ka-band has the highest frequency range of 26.5 to 40 GHz and is used by communications satellites and military targeting radars.
