AP Discovery is a crucial aspect of Wi-Fi 6E technology.

In the past, wireless devices used an active "hunt-and-seek" approach to scan for existing APs, but this is now discouraged in Wi-Fi 6E on the 6 GHz band.

This traditional approach involved sending probe request frames along the 2.4 GHz and 5 GHz frequency spectrum, which is no longer necessary or efficient.

The 6 GHz band uses in-band discovery, which comes in three methods: Fast Initial Link Setup (FILS), unsolicited probe response (UPR) frames, and Preferred Scanning Channels (PSC).

PSC is an active method of in-band discovery, where client devices are limited to sending probe requests on every fourth 20 MHz channel.

Out-of-band discovery is used for cross-communication on all 3 frequency bands, and is known as reduced neighbor reporting (RNR).

Dual-band or tri-band APs operating in the 6 GHz band as well as in a lower band (2.4 GHz or 5 GHz) will be discoverable by scanning the lower bands.

This makes it easier for client devices to roam between 6 GHz and 2.4 or 5 GHz networks, reducing the need for probe requests.
