The IEEE C band is a designation for a portion of the electromagnetic spectrum in the microwave range of frequencies. Specifically, it covers the frequency range from 4.0 to 8.0 GHz. This band is widely utilised for various applications, including satellite communications, radar systems, and some Wi-Fi devices. In satellite communications, the C band is favoured for its relatively low susceptibility to rain fade, which makes it ideal for regions with heavy rainfall. Radar systems often use this band for weather radar and long-range surveillance due to its ability to penetrate through atmospheric conditions. Additionally, some Wi-Fi devices operate in the C band to provide wireless internet services, particularly in areas where the more common 2.4 GHz and 5 GHz bands are congested. The IEEE C band is part of a broader classification system developed by the Institute of Electrical and Electronics Engineers (IEEE) to standardise frequency bands for various technological applications. This standardisation helps in ensuring compatibility and reducing interference between different systems and devices operating within the same frequency range.
