1. FREQUENCY BANDS IN SATELLITE COMMUNICATION PRESENTED BY:- M.ADEEL FAROOQUI

2. FREQUENCY BANDS AVAILABLE FOR SATELLITE COMMUNICATION

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.

• Its 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 30/20GHz band is used in communications satellites , uplink in either the 27.5GHz and 31GHz 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.
