Channel Bandwidth

(Bandwidth) The channel bandwidth is the frequency range in which the energy of a communications signal is concentrated. The bandwidth is centered on the center frequency. For example, the bandwidth of a typical C-band transponder is 36 MHz, more than enough frequency space to transmit a high fidelity video signal via satellite. However, channel bandwidths as low as a half-transponder, 18 MHz, or less are also occasionally used. In addition, while many transponders have 54 and 72 MHz bandwidths, in particular on many Ku-band links, the bandwidth of each video signal may be centered on the upper or lower half of the transponder and occupy typically 27 to 36 MHz or less.
