The 6 GHz band, as defined by the International Telecommunication Union (ITU) Radio Regulations, is a portion of the radio spectrum that falls within the frequency range of 5.925 to 6.425 GHz. The 6 GHz band is globally harmonised through the International Telecommunication Union's Recommendation ITU-R F.383 for microwave technology. However, the specific allocation and regulations can vary by region. In Australia, the Australian Communications and Media Authority (ACMA) manages the use of the 6 GHz band, and it is typically used for applications such as satellite communications, microwave links, and wireless data transmission systems. The 6 GHz band is becoming increasingly important due to its potential for use in next-generation wireless technologies, including WiFi-6E and 5G networks.

Each country develops its own specific operating conditions based on the global ITU-R recommendation, covering information such as antenna sizing, minimum distance requirements, and geographic coordination.
