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]

As an example, assume that the granularity for the search in code phase is 0.5 chips and in frequency is 500 Hz, then there are 1,023/0.5 = 2,046 code phases and 10,000 Hz/500 Hz = 20 frequencies to try for a total of 20×2,046 = 40,920 local replicas. Note that each frequency bin is centered on its interval and therefore covers 250 Hz in each ...
The allocation of radio frequencies is provided according to Article 5 of the ITU Radio Regulations (edition 2012). [2]In order to improve harmonisation in spectrum utilisation, the majority of service-allocations stipulated in this document were incorporated in national Tables of Frequency Allocations and Utilisations which is with-in the responsibility of the appropriate national frequency ...

The NATO C-band is the obsolete designation given to the radio frequencies from 500 to 1000 MHz (equivalent to wavelengths between 0.6 and 0.3 m) during the Cold War period. Since 1992, frequency allocations, allotment and assignments are in line with the NATO Joint Civil/Military Frequency Agreement (NJFA). [ 1 ]
INSAT-4A was the first one in the INSAT-4 Satellites series, providing services in the K u and C band frequency bands. At the time of launch, it was the heaviest satellite India had produced. The K u transponders cover the Indian main land and C-Band transponders cover an extended area. It has a dozen K u transponders and another dozen of C ...
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 . [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 well as an atmospheric ...
