The C band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4.0 to 8.0 gigahertz (GHz). [ 1 ] However, the U.S. Federal Communications Commission C band proceeding and auction, designated 3.7–4.2 GHz as C band. [ 2 ]

Television receive-only (TVRO) is a term used chiefly in North America, South America to refer to the reception of satellite television from FSS -type satellites, generally on C-band analog; free-to-air and unconnected to a commercial DBS provider. TVRO was the main means of consumer satellite reception in the United States and Canada until the ...
The K u band (/ ˌ k eɪ ˈ j uː /) is the portion of the electromagnetic spectrum in the microwave range of frequencies from 12 to 18 gigahertz (GHz). The symbol is short for "K-under" (originally German: Kurz-unten), because it is the lower part of the original NATO K band, which was split into three bands (K u, K, and K a) because of the presence of the atmospheric water vapor resonance ...
The first satellite television dishes were built to receive signals on the C-band analog, and were very large. The front cover of the 1979 Neiman-Marcus Christmas catalog featured the first home satellite TV stations on sale. [2] The dishes were nearly 20 feet (6.1 m) in diameter. [3]
C band (infrared) In infrared optical communications, C-band (C for "conventional") refers to the wavelength range 1530–1565 nm, which corresponds to the amplification range of erbium doped fiber amplifiers (EDFAs). [1] The C-band is located around the absorption minimum in optical fiber, where the loss reaches values as good as 0.2 dB/km, as ...
Satellite description. Eutelsat 8 West B is a 5,782 kg (12,747 lb) satellite with a design life of 15 years. It is equipped with an S400-12 apogee motor which was used for initial orbit-raising manoeuvres and an S10-18 engine for station keeping burns. [1] The spacecraft has 10 C-band and 40 Ku-band transponders. [2]
24 J band. Eutelsat 113 West A, formerly Satmex-6, is a geostationary communications satellite which is operated by Eutelsat. Originally built for Mexico's Satmex, it was launched in 2006. The satellite was acquired by Eutelsat in its 2014 merger with Satmex, and renamed Eutelsat 113 West A in May. [2] It is used to provide communications ...
