Satellite Communication - Part 3 (Frequency Allocation)

Frequency Spectrum Allocation

 

As you can see the picture above,  that the frequency spectrum that allocated in telecommunication. This post is focus only to frequency spectrum that used in satellite communication.

Intermediate Frequency (IF) Band

    Mainly used in Satellite modem equipment in modulator and demodulator side. 

    Range of spectrum is around 70 MHz (50 MHz to 90 MHz)

L-Band

    Also mainly used in Satellite modem equipment in modulator and demodulator side.

    Range of spectrum is 950 MHz to 2150 MHz

C-Band

Primary used in satellite communication for frequency used communication between ground segmen and the satelllite. For this range of spectrum, Uplink frequency (from ground segment to satellite) is around 6 GHz and Downlink frequency (from satellite to ground segment) is around 4 GHz.

Ku-Band

Used in satellite communication for frequency used communication between ground segmen and the satelllite too. For this range of spectrum, Uplink frequency (from ground segment to satellite) is around 14 GHz and Downlink frequency (from satellite to ground segment) is around 12GHz.

Ka-Band

New option in satellite communication spectrum frequency. In this Frequency, Uplink frequency is 30 GHz and Downlink frequency is 28 GHz.
