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.

3. SATELLITE FREQUENCY BANDS The three most commonly used satellite frequency bands are C-band Ku-band Ka-band.

4. C-BAND C band is a name given to certain portions of the electromagnetic spectrum , as well as a range of wavelengths of light , used for communications. Most commercial satellites use this Band. The bandwidth allocated is limited to 500 MHz. Known as 4 / 6 GHz band.

5. C-BAND (Cont…) Up / Down Links (W.R.T Satellite) 3.7 to 4.2 GHz forms the down-link (transmit) frequency 5.925 to 6.425 GHz the up-link (receive) frequency. It’s used for certain satellite television broadcasts, and by some WIFI devices, cordless phones , and weather radars .

6. KU-BAND Ku band is primarily used for satellite communications . The Ku band ( pronounced "kay-yoo" ) is a portion of the electromagnetic spectrum in the microwave range of frequencies. This symbol refers to "K-under" (in the original German, "Kurz-unten", with the same meaning)—in other words.

7. KU-BAND (Cont…) Future satellites are being designed for the Ku-Band. Known as 12 / 14 GHz. Up / Down Links (W.R.T. Satellite) Either 11.7 to 12.2 GHz or 10.95 to 11.2 or 11.45 to 11.7 GHz down Link. 14.0 to 14.5 GHz; up-link frequency. Ku band satellites are also used for backhauls and particularly for satellite from remote locations back to a television network's studio for editing and broadcasting .

8. Ka-BAND The Ka band (Pronounced: "Kay-A Band") covers the frequencies of 26.5-40GHz. The Ka band is part of the K band of the microwave band of the electromagnetic spectrum . The so-called 30/20 GHz band is used in communications satellites , uplink in either the 27.5 GHz and 31 GHz bands, and high-resolution, close-range targeting radars aboard military airplanes. Some frequencies in this radio band are used for vehicle speed detection by law enforcement.
