Anchor and Non-Anchor APs

All 6 GHz Standard Power AFC with Geo-Location Agent Support deployments require anchor and non-anchor APs.

Anchor APs

An integral GPS module supplies geo-location coordinates to anchor APs. The AP5050D/U is currently the only supported anchor AP.

The 6GHz SP APs with integral GPS module bring up SP spectrum based on geo coordinates derived from one of the following sources, according to the listed priority:
  1. Geo coordinates derived by the Geo-Location Agent.
  2. Geo coordinates provided by the integral AP GPS module.

If an anchor AP is unable to derive geo coordinates from the Geo-Location Agent, the AP uses coordinates from its integral GPS module. This ensures a high degree of certainty that the anchor AP does not have sufficient connectivity to complete a subgraph before it switches to using coordinates from its GPS module. This is optimal in cases where many APs in a subgraph lock on to the anchor AP GPS coordinates, and there is a subset of APs that must derive coordinates from the Geo-Location Agent.

Non-Anchor APs

The Geo-Location Agent running on ExtremeCloud IQ assigns geo-location coordinates to all APs under its control.

  • The AP4020, AP5020, AP5022, and AP5060U/D are non-anchor APs that support SP and require an anchor for AFC Geo-Location Agent support (because they do not include their own GPS module).

  • The AP5050 has an integral GPS module, supports SP, and can be used as an anchor or a non-anchor AP depending on your deployment needs.

  • The AP5010 and AP3000 can be configured to support FTM AP-to-AP ranging and participate as non-anchor APs in providing higher geo-location density for the construction and extension of AFC subgraphs. These APs do not support SP and are not required for AFC.
