The three most commonly used The three most commonly used
satellite frequency bands aresatellite frequency bands are
C-bandC-band
Ku-bandKu-band
Ka-band.Ka-band.

4. C-BANDC-BAND

electromagnetic spectrumelectromagnetic spectrum, as well as a range of , as well as a range of
wavelengthswavelengths of of lightlight, used for communications. , used for communications.
Most commercial satellites use this Band.
The bandwidth allocated is limited to 500 MHz.
Known as 4 / 6 GHz band.

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 It’s used for certain satellite televisiontelevision
broadcasts, and by some WIFI devices, broadcasts, and by some WIFI devices,

The The Ku bandKu band ( (pronouncedpronounced "kay-yoo""kay-yoo") is a ) is a
portion of the portion of the electromagnetic spectrumelectromagnetic spectrum in in
the the microwavemicrowave range of frequencies. This range of frequencies. This
symbol refers to "K-under" (in the original symbol refers to "K-under" (in the original
German, "Kurz-unten", with the same German, "Kurz-unten", with the same
meaning)—in other words.meaning)—in other words.

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
broadcastingbroadcasting. .
