NATO C band
IEEE C band
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.
C band is highly associated with TVRO satellite reception systems, commonly called "big dish" systems since small receiving antennas are not optimal for C-band systems. Typical antenna sizes on C-band capable systems ranges from 7.5 to 12 feet (2.5 to 3.5 meters) on consumer satellite dishes, although larger ones also can be used.
The 5.4GHz band (5.15–5.35/5.47–5.725/5.725–5.875 GHz) is used for IEEE 802.11a WIFI and cordless phone applications, leading to occasional interference with C band weather radars.
C band variants
Slight variations of C band frequencies are approved for use in various parts of the world.
