On September 28, 2021 the FCC released a Public Notice announcing the beginning of the process for authorizing 6 GHz Band Automated Frequency Coordination Systems (ET Docket No 21-352). The FCC’s earlier 6 GHz report and Order authorized two different types of unlicensed operations in the 6 GHz band, standard power operations and low power operations (WIFI 6e devices for example). Standard power access points and fixed client devices are required to communicate at least once a day with an automated frequency coordination (AFC) system prior to operating to avoid causing interference to incumbent licensed operations. This Public Notice summarizes the requirements for AFS systems, describes the information that must be provided with proposals to operate an AFC system, and describes the procedure for designating AFC system operators.
