PDFThe C-Band is a small portion of the microwave spectrum and is most commonly used by satellite and RADAR companies for long-distance communications. Its frequency range is defined by IEEE as 4 - 8GHz, with 3.7-4.2GHz commonly used for downlink and 5.925 - 6.425GHz for uplink.
There are different variations of the C-Band depending on which of the three International Telecommunications Union regions the system is located in. For more information on the C-Band variations around the world, refer to the additional resources below.
