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] The C band is used for many satellite communications transmissions, some cordless telephones, as well as some radar and weather radar systems. A very large use is the high frequency (5.2 GHz) band of Wi-Fi (IEEE 802.11a) wireless computer networks.
