Automatic Frequency Coordination (AFC) is a system that enables unlicensed Wi-Fi users to operate in the same frequency spectrum as licensed users, specifically in the 5.925–6.425 GHz (U-NII-5) and 6.525–6.875 GHz (U-NII-7) frequency spans.
Approved AFC service providers have access to a Regulator's database which stores geolocation coordinates and associated power levels of licensed users operating in the 6 GHz spectrum. For simplicity, in this User Guide, the database is referred to as the AFC server.
The AFC server responds to requests made by ExtremeCloud IQ Controller on behalf of eligible Extreme Networks APs for access to 6 GHz SP spectrum based on the geo-location coordinates of the APs. The AFC server responds by querying its database to verify whether there is an existing licensed 6 GHz service in that geo-location. If there is no conflict with licensed users in the AP's geo-location, the AFC server sends a response to ExtremeCloud IQ Controller specifying over which channels and at which power levels the AP can operate.
ExtremeCloud IQ Controller Smart-RF automatically selects the AP 6 GHz radio channel and power level after the AFC server allocates 6 GHz SP spectrum.
Here are some key points about AFC:
