  • 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.
    • 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.
