What is the bandwidth of C-band satellite frequency?

C band Satellite bandwidth C band satellite has uplink frequency in the range from 5925 to 6425 MHz and downlink in the range from 3700 to 4200 MHz . Different satellites have different number of transponders. Each of this transponder occupy part of the total satellite bandwidth (BW) i.e. 500 MHz.

Satellite Communication (satcom) is based on a specific range of frequencies. The useable radio spectrum ranges from 1Ghz to 300Ghz , where its use for communications ends as the signal becomes infrared, X-Ray and visible light. For maritime satcom, we use the frequencies from 1Ghz up to approx. 30Ghz.
