AFC Support for 6 GHz Standard Power Mode

AFC support for 6 GHz standard power mode

The Automated Frequency Coordination (AFC) 6 GHz Standard Power mode enables Cisco Catalyst IW9167I access points to operate in designated frequency bands with regulated power, coordinated through an AFC service.

  • Standard power APs must obtain available frequencies and power levels from the AFC system before activation.

  • The AFC system determines allowable frequencies and maximum power based on regulatory information (FCC for the United States and ISED for Canada).

  • Transmission power is limited to a maximum of 36 dBm EIRP, and operation is permitted in specific UNII frequency bands.

Reference information for AFC 6 GHz standard power mode

The Cisco Catalyst IW9167I supports AFC 6 GHz Standard Power mode, requiring APs to coordinate with the AFC system for frequency and power assignments. The AFC system uses regulatory data and AP characteristics to model interference and assign channels.

  • Standard power APs coordinate through an AFC service using AP location and antenna data to avoid interference.

  • In the U.S., operation is allowed in the UNII-5 (5.925–6.425 GHz) and UNII-7 (6.525–6.875 GHz) bands.

  • From Release 17.18.1, the -A (Canada) domain supports standard power using AFC in the UNII-5, UNII-6, and UNII-7 bands (5.925–6.875 GHz).

Verify AFC status on an AP

This procedure describes how to verify the AFC request and response data, as well as the current operating power mode, on an AP using commands.

Procedure

Step 1

Use the show rrm afc command to verify the AFC request and response data on the AP.

Example:

Device# show rrm afc

Location Type: 1
Deployment Type: 2
Height: 129
Uncertainty: 5
Height Type: 0
Request Status: 5
Request Status Timestamp: 2023-08-31T06:20:17Z
Request Id Sent: 5546388983266789933
Ellipse 1: longitude: -121.935066 latitude: 37.512830 major axis: 43 minor axis:

AFC Response Request ID: 5546388983266789933
AFC Response Ruleset ID: US_47_CFR_PART_15_SUBPART_E

Step 2

Use the show controllers dot11Radio 2 | i Radio command to verify the current operating power mode.

Example:

Device# show controllers dot11Radio 2 | i Radio
