The 22 GHz ITU wireless band, as defined by the ITU Radio Regulations ITU-R F.637, is a specific frequency band within the radio spectrum used for microwave transmission. Sitting within the K-band, the band ranges from 21.2 GHz to 23.6 GHz. It is utilised for various applications, including satellite communication, radar systems, and data transmission. The ITU (International Telecommunication Union) is responsible for the global coordination of these bands to ensure interference-free operation of telecommunication systems.
