### AI overview

This article explains how Automated Frequency Coordination governs 6 GHz Standard Power Wi-Fi access points. It covers incumbent protection, location reporting, cloud-based channel and power grants, 24-hour re-authorization, and fallback behavior when an access point cannot contact the AFC service.

### Source excerpt

AFC protects fixed point-to-point microwave links. A Standard Power AP reports latitude, longitude, and height with a stated uncertainty, re-authorizes every 24 hours, and lives with an upside-down V of excluded spectrum. The hard part indoors is location: GNSS anchors near windows, derivation hops, and uncertainty the AFC treats as risk. With bench notes from a 9800-CL that reports exactly why it is blocked. Second of four posts on 6 GHz power modes.
