C-band

C band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4 to 8 GHz.. It was the first frequency band allocated for commercial ground-to-satellite communications. A typical C-band satellite uses 3.7–4.2 GHz for downlink, and 5.925–6.425 Ghz for uplink.C band is primarily used for open satellite communications, whether for full-time satellite TV networks or raw satellite feeds, although subscription programming also exists. This use contrasts with direct broadcast satellite, which is a completely closed system used to deliver subscription programming to small satellite dishes connected to proprietary receiving equipment.
