6 GHz Extended Range & AFC in UniFi

What is AFC?

AFC (Automatic Frequency Coordination) is a feature in UniFi Network designed for 6 GHz WiFi that increases transmit power while complying with FCC Standard Power Limits. It ensures devices operate on available frequencies without interfering with licensed users, such as satellite and fixed wireless services. Outdoor APs require AFC, while indoor APs can use it for extended range on 6 GHz.

How does AFC work?

AFC-enabled APs connect to a geolocation service via the internet to identify licensed 6 GHz users in your area. Based on this information, the AP automatically selects a channel and adjusts transmit power to prevent interference while optimizing performance.

Why is AFC required?

The 6 GHz band is shared with licensed incumbents, including public safety, broadcasting, and utility operators. AFC is mandated by regulations to protect these critical services while enabling enhanced performance for WiFi devices. Note that AFC for indoor 6 GHz deployments is not required unless the extended range functionality is desired.

What regions utilize AFC?

Currently, only the United States supports AFC and 6 GHz for outdoor APs. Support for additional regions is pending regulatory approval. The current list of supported countries can be found here.

What data is shared during the AFC process?

AFC requires sharing specific device data—such as location and frequency—with Ubiquiti and its service providers to ensure compliance and functionality. For more information, please review our Privacy Policy.
